Over the past twenty years, it has been proven that a history of preeclampsia entails a 4-fold risk of hypertension, coronary heart disease, stroke, type 2 diabetes, metabolic syndrome in the affected women at the age of 50-55 years. Evaluation of intima-media thickness (IMT) has diagnostic value for the assessment of remodeling and atherosclerotic vascular lesions and practical importance as a predictor of vascular accidents in patients with hypertension and atherosclerosis. The aim. To evaluate the IMT as an integrative biomarker of the occurrence of cardiovascular pathology in women with hypertensive disorders of pregnancy in their advanced reproductive age and in perimenopausal age. Materials and methods. We studied 51 women at the age of 48-55 years with the history of severe preeclampsia. The women were asked to fill out a questionnaire in which they indicated the presence of a diagnosis of hypertension, angina pectoris at the time of filling the questionnaire. The diagnosis of hypertension and angina attacks as well as other descriptions of the disease were taken away from the results of the women’s questionnaire. The investigators were not given copies of medical records. The control group consisted of 20 women aged 48-55 who had no history of preeclampsia or any other hypertensive disorders of pregnancy. Ultrasound imaging of the carotid arteries was performed according to the recommendations of the American Society of Echocardiography 2020 in women of both groups using SonoAce-8000 Ex scanner (Medison, South Korea) with a linear sensor UST5524 with a frequency of 7 MHz. IMT less than 0.7 mm was taken as a normal value for women. Results. It was revealed that almost every fourth woman at the age of 48-55 with the history of preeclampsia had signs of early angina attacks, and 30% suffered from hypertension. A threatening fact is that almost 6% of women at the age of 48-55 had the history of vascular thrombosis which is a manifestation of early atherosclerotic vascular lesions in the group of women with gestational hypertensive disorders. It is noteworthy that 21 (41.2%) women with the history of severe preeclampsia felt healthy and did not have any complaints. Importantly, among the women surveyed who had no health complaints, 66.6% (14 of 21) had IMT 0.85±0.01 mm. This accounts for about one third (27.4%) among 51 patients. This category of women is at high risk of developing cardiovascular complications in the future and require further monitoring and detailed examination. Thrombotic complications (dynamic bowel obstruction, mesenteric vascular thrombosis) were observed in 3 (5.9 %) women at the age of 48-55 with the history of severe preeclampsia. Conclusions. Examinations of women with the history of preeclampsia revealed that women at the age of 48-55 had increased IMT. It should be noted that increased IMT was found both in women with cardiovascular pathology (hypertension, thrombosis, angina attacks) and in asymptomatic patient
在过去的二十年里,已经证明先兆子痫病史会使50-55岁的女性患高血压、冠心病、中风、2型糖尿病和代谢综合征的风险增加4倍。内膜-中层厚度(IMT)的评估对评估重塑和动脉粥样硬化性血管病变具有诊断价值,并作为高血压和动脉粥样硬化患者血管意外的预测指标具有实际意义。目标。评估IMT作为一种综合性生物标志物在育龄晚期和围绝经期妊娠期高血压疾病妇女心血管病理发生率中的作用。材料和方法。我们研究了51名年龄在48-55岁之间有严重先兆子痫病史的女性。这些女性被要求填写一份问卷,在问卷中表明她们在填写问卷时被诊断为高血压、心绞痛。高血压和心绞痛发作的诊断以及对该疾病的其他描述从女性问卷的结果中删除。调查人员没有得到医疗记录的复印件。对照组由20名年龄在48-55岁之间的女性组成,她们没有先兆子痫或任何其他妊娠期高血压疾病的病史。根据美国超声心动图学会2020的建议,使用SonoAce-8000 Ex扫描仪(Medison,韩国)和频率为7MHz的线性传感器UST5524对两组女性进行颈动脉超声成像。IMT小于0.7mm被视为女性的正常值。后果研究表明,在48-55岁有先兆子痫病史的女性中,几乎每四分之一都有早期心绞痛发作的迹象,30%患有高血压。一个威胁性的事实是,在48-55岁的女性中,近6%的人有血管血栓形成史,这是妊娠期高血压疾病女性早期动脉粥样硬化性血管病变的表现。值得注意的是,21名(41.2%)有严重先兆子痫病史的女性感觉健康,没有任何抱怨。重要的是,在没有健康问题的受访女性中,66.6%(21人中有14人)的IMT为0.85±0.01 mm。这在51名患者中约占三分之一(27.4%)。这类女性未来患心血管并发症的风险很高,需要进一步监测和详细检查。在3名(5.9%)48-55岁有严重先兆子痫病史的女性中观察到血栓并发症(动态肠梗阻、肠系膜血管血栓形成)。结论。对有先兆子痫病史的女性进行的检查显示,48-55岁的女性IMT增加。值得注意的是,在有心血管疾病(高血压、血栓形成、心绞痛发作)的女性和无症状患者中都发现IMT增加。考虑到IMT增加是高血压患者靶器官损伤的特征之一,也是无症状患者心血管事件的标志,在有严重先兆子痫病史的女性的随访中纳入这项检查很重要,以避免早期严重心血管疾病的发展。

The article presents the principles of providing care for injuries to the heart, aorta, pulmonary artery, or other main vessels. The described principles can be applied in the treatment of civil injuries. The aim. Consider a treatment tactic in the cases of heart and main vessels combat injuries using own experience. Materials and methods. Twelve cases of combat wounds of blood circulation organs in the chest were analyzed: 5 gunshot injuries of the subclavian vessels, 4 gunshot injuries of the heart, 1 gunshot injury of the ascending aorta, 1 gunshot injury of the pulmonary artery and 1 suspected gunshot injury of the left ventricle. Also we analyzed 78 cases of combat gunshot injuries of main vessels of other locations: 3 injuries of vessels of the neck, 68 injuries of main vessels of limbs, 6 injuries of iliac arteries, 1 injury of abdominal aorta. Most of the operations, with the exception of those that required artificial blood circulation, were performed in advanced hospitals at the II level of military medical evacuation, which enabled to shorten the time from injury to the performance of the final surgical intervention and save life or limbs. Results and discussion. Two cases with penetrating wounds to the chest and damage to the subclavian vessels were fatal. Death was attributed to uncontrolled chest bleeding. Among the 78 cases of injury of main vessels of other locations, one case with damage to the iliac arteries was fatal, and death also occurred as a result of uncontrolled massive intra-abdominal bleeding. Conclusions. Wounded individuals with unstable hemodynamics against the background of ongoing massive bleeding and with suspicion of injury of the heart or main vessels in the chest should be operated on immediately. Due to the urgency of performing such operations and impossibility of an adequate additional examination, localization and degree of the damage to the organs of the circulatory system is determined during the operation. A thoracoscopic approach can be used in stable patients with non-penetrating gunshot wounds to the heart. In the relatively stable condition of patients with an established injury of the heart, aorta, or pulmonary artery, it is advisable to perform additional examinations. Patients with trauma to the main vessels of the extremities and ischemia thereof need rapid revascularization.
本文介绍了心脏、主动脉、肺动脉或其他主要血管损伤的护理原则。上述原则可适用于民事伤害的处理。的目标。考虑一种治疗策略,在心脏和主要血管战斗损伤的情况下,运用自己的经验。材料和方法。对12例胸部血液循环器官战斗伤进行分析,其中锁骨下血管枪伤5例,心脏枪伤4例,升主动脉枪伤1例,肺动脉枪伤1例,左心室疑似枪伤1例。同时对其他部位主要血管的战斗枪伤78例进行分析,其中颈部血管损伤3例,四肢主要血管损伤68例,髂动脉损伤6例,腹主动脉损伤1例。除需要人工血液循环的手术外,大多数手术都在二级军事医疗后送的先进医院进行,从而缩短了从受伤到进行最后手术干预的时间,挽救了生命或肢体。结果和讨论。两例胸部穿透伤和锁骨下血管损伤是致命的。死亡原因是无法控制的胸部出血。78例其他部位主要血管损伤中,1例因髂动脉损伤而死亡,也因腹内大量出血而无法控制而死亡。结论。在持续大出血的背景下,血流动力学不稳定且怀疑心脏或胸部主要血管受损的受伤人员应立即进行手术。由于进行此类手术的紧迫性和不可能进行适当的额外检查,因此在手术期间确定循环系统器官损伤的位置和程度。胸腔镜入路可用于稳定的心脏非穿透性枪伤患者。在病情相对稳定的心脏、主动脉或肺动脉损伤患者中,建议进行额外检查。四肢主血管损伤及局部缺血患者需要快速血运重建。

Cardiorenal interaction in acute heart failure (AHF) is becoming an increasingly recognized factor to consider in the management of cardiac surgical patients. Achieving adequate control of water balance and simultaneously preserving kidney function is the goal of the optimal management strategy for patients with AHF. The majority of preoperative hospitalizations to intensive care units in patients with infective endocarditis (IE) are associated with the development of AHF. The term “cardiorenal syndrome” (CRS) is used to define kidney dysfunction on the background of AHF. Due to the lack of clear clinical manifestations of CRS in IE, the diagnosis and treatment of this pathology may be delayed and contribute to the increase in the number of postoperative complications. Recent data, both in basic science and in clinical research, have changed our understanding of CRS. To date, several types of impaired interaction between the kidneys and the heart have been identified. The aim. To study the peculiarities of CRS in patients with IE complicated by AHF. Materials and methods. The basis of this study was the clinical data of 41 patients with active IE who were treated at the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine from 1/1/2020 to 8/31/2020. In order to study the features of clinical manifestation and the course of CRS, a comparative analysis was conducted based on the history and results of laboratory and instrumental research for the group of patients with IE complicated by preoperative AHF, and patients without clinical manifestations of AHF at the time of hospitalization. For an in-depth study of myocardial damage in heart failure, troponin, NT-proBNP, lactate levels were analyzed; dysfunction of the urinary system was assessed by the level of urea and serum creatinine, the volume of diuresis. Results. A reliable relationship between the levels of NT-proBNP and serum creatinine at the preoperative stage was revealed (p˂0.001), as an indicator of the presence of CRS in patients with IE. In the early postoperative period, signs of CRS persisted in patients with IE complicated by preoperative AHF (serum creatinine 157.0±8.5 μmol/l [p<0.001], NT-proBNP 8214.9±2390.0 pg/ml [p=0.010]). Normalization of kidney function indicators was reported on the day 14 after surgery. Conclusions. Cardiac surgical intervention in patients with IE contributes to reduction of CRS manifestations on the day 14 of the postoperative period.
急性心力衰竭(AHF)中的心肾相互作用正成为心脏外科患者管理中越来越需要考虑的因素。实现水平衡的充分控制并同时保持肾功能是AHF患者最佳管理策略的目标。大多数感染性心内膜炎(IE)患者术前入住重症监护室与AHF的发展有关。术语“心肾综合征”(CRS)用于定义AHF背景下的肾功能障碍。由于IE中CRS缺乏明确的临床表现,这种病理的诊断和治疗可能会延迟,并导致术后并发症的增加。基础科学和临床研究的最新数据改变了我们对CRS的理解。到目前为止,已经确定了几种类型的肾脏和心脏之间的相互作用受损。目标。研究慢性疲劳综合征合并AHF患者CRS的特点。材料和方法。本研究的基础是乌克兰国家医学科学院国家阿莫索夫心血管外科研究所2020年1月1日至2020年8月31日期间接受治疗的41名活动性IE患者的临床数据。为了研究CRS的临床表现特点和病程,在实验室和仪器研究的历史和结果的基础上,对IE合并术前AHF的患者组和住院时没有AHF临床表现的患者组进行了比较分析。为了深入研究心力衰竭患者的心肌损伤,分析了肌钙蛋白、NT-proBNP、乳酸水平;通过尿素和血清肌酐水平以及利尿量来评估泌尿系统功能障碍。后果术前NT-proBNP水平与血清肌酐水平之间存在可靠关系(p 0.001),作为IE患者CRS存在的指标。在术后早期,合并术前AHF的IE患者的CRS症状持续存在(血清肌酐157.0±8.5μmol/l[p<0.001],NT-proBNP 8214.9±2390.0 pg/ml[p=0.010])。术后第14天报告肾功能指标正常化。结论。IE患者的心脏手术干预有助于减少术后第14天CRS的表现。

Selective coronary angiography (CAG) is an invasive diagnostic method for the assessment of the internal lumen and anatomical features of the coronary artery. This is a routine procedure and the basis for choosing the tactics of management of patients with coronary artery disease (CAD). However, CAG is a two-dimensional imaging, and despite the use of the poly projection imaging, there may be difficulties in assessing of the degree of stenosis (even by experienced operators, especially in 50–70% lesions). Along with multivessel disease (stenostes of 2 or more main coronary arteries with a diameter of more than 2 mm), this may cause difficulties in interpreting the results of the study and choosing further volume of revascularization (the number of treated stenosis). In these cases, it is necessary to use a combination of CAG with additional functional methods for diagnosing the significance of each coronary stenosis and its role in the occurrence of myocardial ischemia. The aim. To analyze the clinical results of stenting with invasive measurement of fractional flow reserve when choosing the volume of revascularization of 50–70% coronary artery stenoses. Materials and methods. The results of interventions in 109 patients treated at the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine from 2017 to 2022 with CAD were studied; in these patients, CAG revealed >50–70% multivessel coronary artery disease. They were divided into two groups: fractional reserve group (main group) undergoing stenting of only symptomatic stenosis according to intracoronary physiological examination (n = 52; 47%), and control group (anatomical revascularization, n = 57; 53%) where stenting was determined according to angiography. Conclusion. Interventional treatment of multivessel CAD with fractional flow reserve assessment enables to avoid inappropriate stenting of hemodynamically insignificant stenoses, thus it is possible to optimize treatment tactics of this group of patients (reduce the number of implanted stents).
选择性冠状动脉造影(CAG)是一种评估冠状动脉内腔和解剖特征的侵入性诊断方法。这是一个常规程序,也是选择冠状动脉疾病(CAD)患者管理策略的基础。然而,CAG是一种二维成像,尽管使用了多投影成像,但在评估狭窄程度方面可能存在困难(即使是经验丰富的操作员,尤其是50-70%的病变)。与多血管疾病(2条或2条以上直径超过2毫米的主要冠状动脉狭窄)一起,这可能会导致解释研究结果和选择进一步的血运重建体积(治疗狭窄的数量)方面的困难。在这些情况下,有必要将CAG与其他功能方法相结合,以诊断每种冠状动脉狭窄的意义及其在心肌缺血发生中的作用。目标。在选择50-70%冠状动脉狭窄的血运重建体积时,分析支架置入术与血流储备分数的侵入性测量的临床结果。材料和方法。研究了2017年至2022年在乌克兰国家医学科学院国家阿莫索夫心血管外科研究所接受治疗的109名CAD患者的干预结果;在这些患者中,CAG显示>50-70%的多支冠状动脉疾病。他们被分为两组:部分储备组(主要组)根据冠状动脉内生理检查仅对症状性狭窄进行支架植入(n=52;47%),对照组(解剖血运重建,n=57;53%)根据血管造影术确定支架植入。结论通过血流储备分数评估对多血管CAD进行介入治疗,可以避免对血流动力学上不重要的狭窄进行不适当的支架植入,因此可以优化这组患者的治疗策略(减少植入支架的数量)。

Interventional treatment of multivessel CAD with fractional flow reserve assessment enables to avoid inappropriate stenting of hemodynamically insignificant stenoses, thus it is possible to optimize treatment tactics of this group of patients (reduce the number of implanted stents).","PeriodicalId":33680,"journal":{"name":"Ukrayins''kii zhurnal sertsevosudinnoyi khirurgiyi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42123454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 1992, Brugada brothers first described the clinical-electrocardiographic syndrome which was characterized by changes in the electrocardiogram (ECG), family history of syncopal states and sudden cardiac death (SCD) in the absence of structural heart disease. The standard therapy recommended by the European Society of Cardiology for the prevention of SCD in type I Brugada syndrome (BS) is implantation of a cardioverter-defibrillator. Radiofrequency ablation (RFA) of BS has been performed since the 2000s as an alternative therapy for BS with recurrent ventricular arrhythmias. To date, more than 300 such interventions have been performed by various centers around the world, and multicenter randomized trials are underway to study the long-term results of catheter destruction. We reviewed our experience of catheter ablation in a patient with BS. The patient suffered from ventricular arrhythmias and short-term loss of consciousness. ECG and 24-hour monitoring data recorded ventricular arrhythmias of more than 34% per day and type II BS. Electroanatomical mapping and RFA of the areas with low amplitude graphics were performed by endocardial access. This zone coincided with the earliest activation of the myocardium during ventricular arrhythmias. Extrasystoles were eliminated. In the remote period (10-12 weeks) the patient had no ventricular arrhythmias and there are also no ECG signs of BS. Most major arrhythmological centers perform RFA with epicardial access. Our patient chose the endocardial approach as safer. In her specific case, localization of arimogenic substrate allowed to limit this access, and RFA was successful.
1992年,Brugada兄弟首次描述了临床心电图综合征,其特征是在没有结构性心脏病的情况下,心电图(ECG)改变、晕厥状态家族史和心源性猝死(SCD)。欧洲心脏病学会推荐的预防I型Brugada综合征(BS) SCD的标准治疗是植入心律转复除颤器。自2000年代以来,射频消融(RFA)作为BS伴复发性室性心律失常的替代治疗已被实施。迄今为止,世界各地的不同中心已经进行了300多次这样的干预,多中心随机试验正在进行中,以研究导管破坏的长期结果。我们回顾了导管消融治疗一例BS患者的经验。患者患有室性心律失常和短期意识丧失。心电图和24小时监测数据记录了每天超过34%的室性心律失常和II型BS。通过心内膜通路对具有低振幅图形的区域进行电解剖作图和射频成像。此区与室性心律失常时心肌最早激活的时间一致。早搏消除。远期(10-12周)患者无室性心律失常,也无BS的心电图征象。大多数主要的心律失常中心在心外膜通路下进行射频消融。我们的病人选择心内膜入路更安全。在她的特殊病例中,致氨源性底物的定位限制了这种通路,RFA是成功的。

Background. The current state of interventional cardiology is aimed at reducing the number of probable complica-tions of procedures and increasing patient comfort. That is why there was a stage evolution of changing endovascular ap-proaches from transfemoral to transradial. But despite the significant benefits of transradial access, it leaves behind some important complications. One such complication is occlusion of the radial artery. The frequency of this situation ranges from 1 to 30%. That is why the world’s leading interventionists are increasingly using distal transradial access, which is associated with fewer cases of postoperative occlusion of the radial artery. The aim. Occlusion of the radial artery is not an obstacle to changing access to the contralateral artery or more dan-gerous transfemoral access. With distal transradial access it is possible to recanalize artery and provide target procedure. Materials and methods. The study included 318 patients who were scheduled for re-intervention. Among these patients, 12 had a radial artery occlusion, which is 3.7% of the total control group. Successful recanalizations with distal access were performed in 9 patients (75%), and in 3 patients (25%) the attempts were unsuccessful. The technique of recanalization of chronic occlusion included selection of hydrophilic, both non-coronary and coronary wires. At the end of the procedure, hemostasis was performed according to standard procedures using aseptic bandages. Complications of hemostasis were not detected in any patient in the control group. The postoperative period was unremarkable. Conclusions. The study showed the possibility of using distal transradial access to recanalize chronic occlusions of the radial artery, which allows not to waste time on replacement of the contralateral radial artery or life-threatening transfemoral access and perform the necessary amount of the intervention. Besides, this preserves the radial artery for further use in bypass surgery or hemodialysis arteriovenous fistula.
背景介入心脏病学的现状旨在减少可能的并发症数量,增加患者的舒适度。这就是为什么血管内方法从经股动脉到经桡动脉发生阶段性变化的原因。但是,尽管经桡动脉入路有显著的好处,但它也留下了一些重要的并发症。其中一种并发症是桡动脉闭塞。这种情况发生的频率在1%到30%之间。这就是为什么世界领先的干预学家越来越多地使用远端经桡动脉入路,这与术后桡动脉闭塞的病例减少有关。目标。桡动脉闭塞并不是改变对侧动脉通路或更大范围经股通路的障碍。通过远端经桡动脉入路,可以再通动脉并提供靶向手术。材料和方法。这项研究包括318名计划再次干预的患者。在这些患者中,12名患者患有桡动脉闭塞,占总对照组的3.7%。9名患者(75%)成功进行了远端再通,3名患者(25%)尝试未成功。慢性闭塞的再通技术包括选择亲水性、非冠状动脉和冠状动脉导线。手术结束时,根据标准程序使用无菌绷带进行止血。对照组中未发现任何患者出现止血并发症。术后时间并不明显。结论。该研究表明,使用远端经桡动脉通路重新通入桡动脉慢性闭塞的可能性,这样就不会浪费时间更换对侧桡动脉或危及生命的经股通路,并进行必要的干预。此外,这保留了桡动脉,以便在搭桥手术或血液透析动静脉瘘中进一步使用。

Introduction. Cardiac tumors (CT) occur in 0.3-0.7% of general population according to autopsies. The combination of CT with coronary artery disease (CAD) significantly complicates the clinical course of the disease. The aim. To study the frequency, features of the course and surgical treatment of patients with CT combined with CAD. Materials and methods. In the period from 01.01.1969 to 31.12.2020, surgical treatment of 976 patients with CT was performed at the National Amosov Institute of Cardiovascular Surgery of the NAMS of Ukraine, and 41 (4.2%) of these patients had lesions of the coronary arteries. In 39 patients (95.1%), CT were represented by benign tumors (myxomas), in 2 (2.4%) by malignant, poorly differentiated sarcoma and immature teratoma. For the correction of the pathology of coronary vessels, a whole range of surgical methods was used: stenting of left anterior descending artery (LAD), which was performed immediately before surgery to remove CT, in 3 patients (7.3%); coronary artery bypass grafting in 35 patients (85.4%); in cases of the presence of a muscular bridge that narrowed the LAD, dissection of this structure was performed in 2 patients (4.9%); left ventricular aneurysm repair surgery in 1 patient (2.4%). In 7 patients (17.1%), the operation was performed on urgent indications. Results. The average number of grafted arteries was 1.9 ± 0.3 (1 to 4) per patient. There were no mortality. Of the 41 patients with coronary artery lesions with CT, there were 2 cases of acute CAD as a result of their embolism by tumor fragments. Clinical manifestations in these patients differed significantly. Conclusions. Occurrence of coronary artery embolism in patients with CT according to our data is 0.2% of all patients with CT. CAD accompanies tumor lesions in 4.1% of cases and is diagnosed by angiography and computed tomography. To correct the lesion of the coronary arteries in CT, the full range of surgical techniques is used, including stenting of the coronary artery (spacecraft), coronary artery bypass grafting, removal of the myocardial bridge.
介绍根据尸检,心脏肿瘤(CT)发生在0.3-0.7%的普通人群中。CT与冠状动脉疾病(CAD)的结合显著地使疾病的临床过程复杂化。目标。探讨CT合并CAD患者的发病率、病程特点及手术治疗。材料和方法。1969年1月1日至2020年12月31日期间,乌克兰国立阿莫索夫心血管外科研究所对976名CT患者进行了手术治疗,其中41名(4.2%)患者有冠状动脉病变。39例(95.1%)患者的CT表现为良性肿瘤(粘液瘤),2例(2.4%)为恶性、低分化肉瘤和未成熟畸胎瘤。为了纠正冠状血管的病理,使用了一系列的手术方法:3名患者(7.3%)在手术前立即进行左前降支(LAD)支架置入术,以去除CT;冠状动脉搭桥术35例(85.4%);在存在使LAD变窄的肌桥的情况下,2名患者(4.9%)进行了该结构的解剖;左室动脉瘤修补术1例(2.4%),7例(17.1%)在急诊指征下进行。后果平均每位患者移植动脉数为1.9±0.3(1-4)条。没有死亡。在41例CT冠状动脉病变患者中,有2例因肿瘤碎片栓塞而导致急性CAD。这些患者的临床表现有显著差异。结论。根据我们的数据,CT患者冠状动脉栓塞的发生率为所有CT患者的0.2%。4.1%的病例伴有肿瘤病变,并通过血管造影和计算机断层扫描进行诊断。为了在CT中纠正冠状动脉的病变,使用了全方位的手术技术,包括冠状动脉支架(航天器)、冠状动脉旁路移植术、心肌桥切除术。

Background. Hypertrophic cardiomyopathy (HCM) is an autosomal dominant disease with a prevalence of 1 case per 500 people and is the most common cause of sudden cardiac death in young patients. As clinical manifestations and electrocardiographic data are nonspecific and diverse, noninvasive imaging techniques play a key role in the detection of HCM and the understanding of its pathophysiology. The aim. To evaluate the possibilities of ECG-synchronized cardiac multislice computed tomography (MSCT) as a highly informative diagnostic tool for assessing the morpho-functional state of the heart in patients with HCM. Materials and methods. This was a retrospective analysis conducted at the National Amosov Institute of Cardiovascular Surgery from January 2020 to December 2021. We examined 221 cardiac MSCT scans of patients who underwent the examination to assess the spread of myocardial hypertrophy. Particular attention was paid to the presence of crypts at different levels of the left ventricle (LV), anatomical features of the mitral valve and subvalvular apparatus. The presence of systolic pulling of the anterior mitral valve to the interventricular septum, myocardial mass, LV end-diastolic, LV end-systolic volumes and the corresponding indices of body surface area, ejection fraction were determined and calculated during the functional analysis. Additionally, the anatomy and patency of the coronary arte­ ries were assessed. The studies were performed on a 640-slice Canon Aquilion One CT scanner with retrospective ECG gating and subsequent image processing. The studies were transferred to a workstation for review and evaluation by a team of radiologists. Results. The mean patient age was 46 ± 23 years, 48% were male. Mean maximal LV wall thickness was 19 mm (range 16–34). In 159 patients (71.9%), there was an asymmetric form of HCM with a predominant thickening of the anterior and anteroseptal segments of the left ventricle at the basal and midventricular levels. Fifty-four (24.4%) patients had symmetric form of HCM. The midventricular form of HCM was detected in 4 patients (1.8%). Apical form of HCM was detected in 3 patients (1.3%). One patient was diagnosed with a tumor-like variant of HCM (0.5%). In 198 patients (89.6%), systolic anterior motion of the mitral valve to the interventricular septum was found. In 95 cases (42.9%), morphological abnormality, abnormality of the number or attachment of the papillary muscles were detected. Forty-eight myocardial crypts were detected in 44 patients (21.7%). In 194 patients (87.7%), patent coronary arteries without signs of stenosis were found, 68 patients (30.7%) had 74 myocardial bridges (33.4%). Conclusions. HCM is a genetic heart disease with enormous phenotypic diversity. Due to its high spatial resolution, cardiac MSCT is an accurate diagnostic tool, which allows to assess the morphofunctional state of the LV, mitral valve, subvalvular apparatus, as well as to analyze the anatomy and narrowing of c
背景。肥厚性心肌病(HCM)是一种常染色体显性遗传病,发病率为每500人中有1例,是年轻患者心源性猝死的最常见原因。由于临床表现和心电图资料的非特异性和多样性,无创成像技术在HCM的检测和病理生理学的认识中起着关键作用。的目标。评估心电图同步心脏多层计算机断层扫描(MSCT)作为评估HCM患者心脏形态功能状态的高信息诊断工具的可能性。材料和方法。这是2020年1月至2021年12月在国家阿莫索夫心血管外科研究所进行的回顾性分析。我们检查了221例心脏MSCT扫描的患者,这些患者接受了检查以评估心肌肥厚的扩散。特别注意的是在左心室(LV)的不同水平隐窝的存在,二尖瓣和瓣下装置的解剖特征。在功能分析中,测定并计算二尖瓣前瓣向室间隔的收缩牵拉、心肌质量、左室舒张末期、左室收缩末期容积以及相应的体表面积、射血分数等指标。此外,还评估了冠状动脉的解剖结构和通畅程度。研究是在640层Canon Aquilion One CT扫描仪上进行的,具有回顾性ECG门控和随后的图像处理。这些研究被转移到工作站,由一组放射科医生进行审查和评估。结果。患者平均年龄46±23岁,男性占48%。平均最大左室壁厚为19 mm(范围16-34)。在159例(71.9%)患者中,存在不对称形式的HCM,主要是左心室基底和中水平的前段和前间隔段增厚。对称型HCM 54例(24.4%)。在4例(1.8%)患者中检测到中脑室型HCM。3例(1.3%)患者出现根尖型HCM。1例患者被诊断为肿瘤样HCM变异(0.5%)。198例(89.6%)患者发现二尖瓣向室间隔收缩前移。95例(42.9%)出现形态异常、乳头肌数量异常或附着异常。44例(21.7%)发现48个心肌隐窝。194例(87.7%)无狭窄征象的冠状动脉未闭,68例(30.7%)有74个心肌桥(33.4%)。结论。HCM是一种具有巨大表型多样性的遗传性心脏病。由于其高空间分辨率,心脏MSCT是一种准确的诊断工具,可以评估左室、二尖瓣、瓣下装置的形态功能状态,并分析HCM患者的解剖结构和冠状动脉狭窄。

Carotid near-occlusion (CNO) is the type of severe atherosclerotic stenosis of the internal carotid artery (ICA) with or without collapse of the vessel distally to the narrow part. According to the North American Symptomatic Carotid Endarterectomy Trial (NASCET), severity of ICA stenosis highly correlates with the risk of stroke, except for cases of extremely critical stenosis > 94%, where the risk is lower, and, according to recent guidelines, conservative treatment is preferable. This consideration is questionable due to the recent data about early stroke recurrence and worldwide practice. Rapid improvement of endovascular technique during the last decade makes carotid angioplasty and stenting (CAS) a feasible option for the treatment of patients with CNO and is widely reported in the literature. However, in uncertain circumstances, more scientific data are necessary to fulfill the gap in indications, terms and risks of CAS for CNO. The aim. To evaluate the results of the treatment of patients with CNO after CAS. Materials and methods. Three hundred and fifteen patients were surgically treated at Scientific-Practical Center of Endovascular Neuroradiology of the National Academy of Medical Sciences of Ukraine due to ICA stenosis between 2010 and 2020. Among them, 39 (12.4%) patients (11 woman / 28 men (age 57.9±2.1 years) had CNO and underwent CAS at our Center. Patient population, clinical and radiological investigations, procedure compli-cations were investigated. Procedure complications (stroke, hemodynamic depression [HD] and hyperperfusion syndrome [HPS]) were meticulously studied. All the patients had routine ultrasound and clinical check 30 days after the procedure. Results. All the patients with CNO were successfully stented with the improvement of the site of stenosis after CAS, with only minimal residual stenosis in cases of severe HD. We observed two procedural vascular accidents, first patient had transient ischemic attack (TIA) and one had stroke due to middle cerebral artery occlusion after stent placement and further urgent mechanical thrombectomy. The patient had no neurologic decline and was discharged home. We didn’t observe any cases of myocardial infarction (MI) or death in our series during the hospital stay. HD was seen in 13 (33.3%) patients, and mostly resolved after the procedure except for 3 casesthat required prolonged intensive care unit stay. HPS was diagnosed in 2 (5.1%) patients and also didn’t have anyneurologic consequences after supportive care. During 30 days of follow-up, one (2.6%) patient had TIA because of anti-platelets cessation and 1 (2.6%) patient had MI after 1 week since discharge. All control images revealedstents patency without the evidence of critical residual stenosis. Conclusions. CNO remains important diagnostic and therapeutic challenge. Recent data showed high risk ofrecurrent stroke in case of CNO on best medical therapy, especially at an early stage, but it remains a preferred option ac
颈动脉近端闭塞(CNO)是一种严重的颈内动脉(ICA)动脉粥样硬化性狭窄,狭窄部分远端的血管有无塌陷。根据北美症状性颈动脉内膜切除试验(NASCET),ICA狭窄的严重程度与中风的风险高度相关,但极重度狭窄>94%的病例除外,这些病例的风险较低,根据最近的指南,保守治疗更可取。由于最近关于早期中风复发的数据和世界范围内的实践,这种考虑是值得怀疑的。血管内技术在过去十年中的快速改进使颈动脉血管成形术和支架术(CAS)成为治疗CNO患者的可行选择,并在文献中得到广泛报道。然而,在不确定的情况下,需要更多的科学数据来弥补CAS对CNO的适应症、术语和风险方面的差距。目标。评价CAS后CNO患者的治疗效果。材料和方法。2010年至2020年间,315名患者因颈内动脉狭窄在乌克兰国家医学科学院血管内神经放射学科学实践中心接受了手术治疗。其中39名(12.4%)患者(11名女性/28名男性(年龄57.9±2.1岁)患有CNO,并在我中心接受了CAS。对患者群体、临床和放射学调查、手术并发症进行了调查。仔细研究了手术并发症(中风、血液动力学抑制[HD]和高灌注综合征[HPS])。所有患者在手术后30天进行常规超声检查和临床检查。后果所有CNO患者在CAS术后均成功支架植入,狭窄部位得到改善,严重HD患者的残余狭窄仅为最小。我们观察到两例手术性血管意外,第一例患者发生短暂性脑缺血发作(TIA),一例患者在支架置入和进一步紧急机械血栓切除术后因大脑中动脉闭塞而中风。患者没有神经功能下降,出院回家。在住院期间,我们没有观察到任何心肌梗死(MI)或死亡病例。HD见于13例(33.3%)患者,除3例需要长期重症监护外,大多数患者在手术后得到解决。2名(5.1%)患者被诊断为HPS,在支持性护理后也没有任何神经系统后果。在30天的随访中,一名(2.6%)患者因抗血小板停止而出现短暂性脑缺血发作,一名患者(2.6%)出院1周后出现心肌梗死。所有对照图像显示通畅,无严重残余狭窄的证据。结论。CNO仍然是重要的诊断和治疗挑战。最近的数据显示,在最佳药物治疗的情况下,尤其是在早期阶段,CNO患者复发中风的风险很高,但根据指南,这仍然是首选。考虑到有症状的ICA狭窄患者在CAS后中风率在全球范围内的改善,有必要进行进一步的研究来评估其在CNO情况下的风险,尤其是在完全衰竭的情况下。我们的数据表明,CAS通过仔细的术前诊断和计划,对选定的CNO患者来说是一种有效的手术。

Patients with coronary artery disease (CAD) form a large group among all patients with cardiovascular diseases. Atherosclerosis, as one of the main pathogenetic mechanisms in adverse cardiovascular events development, is one of the leading causes of disability and mortality. Echocardiography is one of the main imaging techniques in managing cardiovascular patients. In search of a new parameter that would reflect both the morphological and functional LV changes, more and more attention has recently been paid to integrated indicators such as the left ventricular global function index (LVGFI) and myocardial contraction fraction (MCF). These parameters are independent predictors of heart failure and cardiovascular diseases. The aim. To evaluate the prognostic value of left ventricular global index and myocardial contraction fraction based on 2D echocardiography results in patients with CAD. Materials and methods. Patients with CAD confirmed by coronary angiography were included in the prospective clinical study. Thirty patients without CAD were a control group, 35 patients had single vessel lesion, 66 had multivessel CAD. LVGFI and MCF were calculated using 2D echocardiography technique. Results. The groups were comparable with respect to age, body mass index (BMI) and comorbidities. The mean age of the patients in group I was 60.53±1.77 years. In group II, the mean age was the highest, 64.31±1.62 years, and in group III the participants were 63.0±1.14 years old. The data indicate the absence of a significant difference (p = 0.39) in the age structure of the patients. In the control group, women predominated (70%), compared to groups II and III, where the proportion of women was 31.2% and 21.2%, respectively (p = 0.0001). The highest BMI classified as obesity class 1 was observed in the first group: 31.74 ± 1.09 kg/m2. Group III had BMI of 30.71 ± 0.62 kg/m2, which also indicates obesity class 1. Group II had the lowest BMI: 29.76 ± 0.77 kg/m2, but the difference between the groups was insignificant (p = 0.432). LVGFI and MCF differed significantly among groups (р=0.003 and р=0.004, respectively). MCF was the highest in patients with multivessel disease – 35.0% (27.71; 42.0), and the lowest in the group with no vascular lesions – 42.29% (36.35; 52.21). LVGFI also was different among the groups. It was the lowest in group III (24.91% [19.22; 30.48]), and the highest in group I (30.85% [25.46; 37.13]). Conclusions. MCF and LVGFI are closely related to the degree of coronary artery involvement. These integral parameters may be used as non-invasive markers of more significant coronary arteries involvement.
在所有心血管疾病患者中,冠状动脉疾病(CAD)患者是一个很大的群体。动脉粥样硬化是心血管不良事件发生的主要发病机制之一,也是致残和死亡的主要原因之一。超声心动图是治疗心血管疾病的主要成像技术之一。为了寻找一个能同时反映左心室形态和功能变化的新参数,最近越来越多地关注左心室整体功能指数(LVGFI)和心肌收缩分数(MCF)等综合指标。这些参数是心力衰竭和心血管疾病的独立预测因素。目标。评价基于二维超声心动图结果的左心室整体指数和心肌收缩率对CAD患者的预后价值。材料和方法。经冠状动脉造影证实的CAD患者纳入前瞻性临床研究。30例无CAD患者为对照组,35例为单血管病变,66例为多血管CAD。采用二维超声心动图技术计算LVGFI和MCF。后果两组在年龄、体重指数(BMI)和合并症方面具有可比性。I组患者的平均年龄为60.53±1.77岁。第二组的平均年龄最高,为64.31±1.62岁,第三组的参与者年龄为63.0±1.14岁。数据表明,患者的年龄结构没有显著差异(p=0.39)。在对照组中,女性占主导地位(70%),而第二组和第三组的女性比例分别为31.2%和21.2%(p=0.0001)。第一组的BMI最高,为1级肥胖:31.74±1.09 kg/m2。III组的BMI为30.71±0.62 kg/m2,这也表明肥胖等级为1。第二组的BMI最低:29.76±0.77 kg/m2,但两组之间的差异不显著(p=0.432)。LVGFI和MCF在各组之间差异显著(分别为р=0.003和р=0.004)。MCF在多血管疾病患者中最高,为35.0%(27.71;42.0),在无血管病变的组中最低,为42.29%(36.35;52.21)。LVGFI在各组之间也有所不同。第三组最低(24.91%[19.22;30.48]),第一组最高(30.85%[25.46;37.13])。MCF和LVGFI与冠状动脉病变程度密切相关。这些积分参数可以用作更显著的冠状动脉受累的非侵入性标志物。
