Objectives: Fetuin-A is a circulating calcification inhibitor that prevents coronary artery calcification (CAC) by increasing calcium phosphate solubility and inhibiting VSMC differentiation and apoptosis. In this study, we investigated the correlation between rs4918 and CAC in patients with coronary artery disease (CAD). Methods: Forty-two healthy individuals and eighty-one CAD patients were recruited in the present study. The CAC score (CACS) was measured by CT angiography and the genotype analysis of rs4918 single-nucleotide polymorphism SNP was performed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Results: The CACS was significantly higher in CAD patients compared to healthy individuals (p < 0.001); however, there was no significant difference between the mean CACS in the presence and absence of rs4918 (p = 0.792). The mean calcium score of the left main coronary artery (LMCA) was significantly lower in carriers of the rs4918 allele (p = 0.036). The frequency of rs4918 SNP was almost similar in the control group and CAD patients (p = 0.846). Conclusions: in patients with CAD, we found no significant association between rs4918 SNP and CACS, indicating that carriers of this allele are not at increased risk of developing cardiovascular diseases compared with those without.
目的:胎球蛋白-A是一种循环钙化抑制剂,通过增加磷酸钙溶解度和抑制VSMC分化和凋亡来预防冠状动脉钙化(CAC)。在本研究中,我们研究了冠状动脉疾病(CAD)患者中rs4918与CAC之间的相关性。方法:本研究招募了42名健康人和81名CAD患者。用CT血管造影术测定CAC评分(CACS),用聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)技术对rs4918单核苷酸多态性SNP进行基因型分析。结果:冠心病患者的CACS显著高于健康人(p<0.001);然而,在rs4918存在和不存在的情况下,平均CACS之间没有显著差异(p=0.792)。rs4918等位基因携带者的左主冠状动脉(LMCA)的平均钙评分显著较低(p=0.036)。对照组和CAD患者中rs4918 SNP的频率几乎相似(p=0.846)。结论:在CAD患者中,我们发现rs4918 SNP和CACS之间没有显著的相关性,这表明与没有rs4918等位基因的携带者相比,该等位基因携带者患心血管疾病的风险没有增加。

Anomalous Left Coronary Artery from the Pulmonary Artery (ALCAPA) is a rare coronary artery anomaly which accounts for 0.25–0.5% of all congenital cardiac diseases, where most die within the first year of life. We present a case report of a 50-year-old lady who presented to hospital with persistent palpitations. Her admission electrocardiogram found her to be in Atrial Fibrillation (AF). She was rate-controlled and subsequently discharged. Despite that, she represented with further episodes of AF and was referred for an outpatient transthoracic echocardiogram. This revealed a dilated right coronary artery, retrograde flow in the left coronary artery and collateral flow in the myocardium. To investigate, the patient had undergone further imaging which confirmed the diagnosis. As such, she was later shortlisted for surgical intervention. Conclusively, our case exemplifies the role of multimodal imaging to identify the features of ALCAPA and may be useful for the purposes of surgical intervention.
肺动脉左冠状动脉异常(ALCAPA)是一种罕见的冠状动脉异常,占所有先天性心脏病的0.25-0.5%,大多数在出生后的第一年内死亡。我们报告了一位50岁的女士,她因持续心悸入院。入院心电图显示她患有心房颤动。她接受了心率控制,随后出院。尽管如此,她还是出现了进一步的房颤发作,并被转诊到门诊进行经胸超声心动图检查。显示右冠状动脉扩张,左冠状动脉逆行,心肌侧支流动。为了调查,患者接受了进一步的影像学检查,证实了诊断结果。因此,她后来入围了手术干预的候选名单。总之,我们的病例证明了多模式成像在识别ALCAPA特征方面的作用,并可能对外科干预有用。

Sudden cardiac death in young athletes: Literature review of molecular basis 年轻运动员的心源性猝死:分子基础的文献综述

Intense athletic training and competition can rarely result in sudden cardiac death (SCD). Despite the introduction of pre-participation cardiovascular screening, especially among young competitive athletes, sport-related SCD remains a debated issue among medical personnel, sports communities and laypersons alike, and generates significant media attention. The most frequent cause of SCD is a hidden inherited cardiomyopathy, the athletes may not even be aware of. Predictive medicine, by searching the presence of pathogenic alterations in cardiac genes, may be an integrative tool, besides the conventional ones used in cardiology (mainly electro and echocardiogram), to reach a definitive diagnosis in athletes showing signs/symptoms, even borderline, of inherited cardiomyopathy/ channelopathy, and in athletes presenting family history of SCD and/or of hereditary cardiac disease. In this review, we revised the molecular basis of the major cardiac diseases associated to sudden cardiac death and the clinical molecular biology approach that can be used to perform risk assessment at DNA level of sudden cardiac death, contributing to the early implementation of adequate therapy. Alterations can occur in ion channel genes, in genes encoding desmosomal and junctional proteins, sarcomeric and Z-disc proteins, proteins for the cytoskeleton and the nuclear envelope. The advent of next generation sequencing (NGS) technology has provided the means to search for mutations in all these genes, at the same time. Therefore, this molecular approach should be the preferred methodology for the aforementioned purpose.
激烈的运动训练和比赛很少会导致心源性猝死(SCD)。尽管引入了参赛前心血管筛查,特别是在年轻竞技运动员中,但与运动相关的SCD仍然是医务人员、体育界和非专业人士争论的问题,并引起了媒体的极大关注。SCD最常见的病因是一种隐性遗传性心肌病,运动员甚至可能都不知道。除了心脏病学(主要是心电图和超声心动图)中使用的传统工具外,预测医学通过搜索心脏基因中是否存在致病性改变,可能是一种综合工具,可以对表现出遗传性心肌病/通道病体征/症状,甚至是临界症状的运动员做出明确诊断,以及存在SCD家族史和/或遗传性心脏病家族史的运动员。在这篇综述中,我们修订了与心源性猝死相关的主要心脏病的分子基础,以及可用于在DNA水平上进行心源性猝死风险评估的临床分子生物学方法,有助于早期实施适当的治疗。离子通道基因、桥粒和连接蛋白、肌粒和Z-盘蛋白、细胞骨架和核膜蛋白的编码基因可能发生改变。下一代测序技术的出现为同时寻找所有这些基因的突变提供了手段。因此,对于上述目的,这种分子方法应该是优选的方法。

Kearns-Sayre Syndrome (KSS) is a rare, mitochondrial disease in which cardiac involvement has been associated with poor prognosis. Although the most common clinical manifestation is progressive conduction system impairment, patients can suffer from ventricular arrhythmias. Yet, they show a high prevalence of sudden cardiac death, whose etiopathological mechanism is not completely understood. Cardiac magnetic resonance (CMR) is a rising tool to detect subclinical heart involvement in many heart diseases and was recently able to detect non-ischemic scar in patients affected by KSS.   We present a case of a 44 years old patient affected by KSS with a long-standing history of ventricular arrhythmias. Despite electrocardiogram and echocardiogram were normal, CMR showed non-ischemic myocardial scar in the basal-mid lateral wall. Ventricular ectopic beats were assumed to origin from this site, according to their morphology. Our case highlights non-ischemic myocardial scar as a possible etiopathological mechanism of ventricular arrhythmias in patients with KSS. The added value of CMR to provide cardiac involvement identification and risk stratification of these patients is also shown.
Kearns-Sayre综合征(KSS)是一种罕见的线粒体疾病,心脏受累与预后不良有关。尽管最常见的临床表现是进行性传导系统损伤,但患者也可能出现室性心律失常。然而,他们显示心脏性猝死的发病率很高,其发病机制尚不完全清楚。心脏磁共振(CMR)是检测许多心脏病亚临床心脏受累的一种新兴工具,最近能够检测KSS患者的非缺血性瘢痕。我们报告了一例44岁的KSS患者,该患者长期有室性心律失常病史。尽管心电图和超声心动图正常,CMR显示基底中外侧壁有非缺血性心肌瘢痕。根据其形态,假定心室异位搏动起源于该部位。我们的病例强调非缺血性心肌瘢痕可能是KSS患者室性心律失常的病理机制。还显示了CMR对这些患者的心脏受累识别和风险分层的附加价值。

The majority of familial noncompaction cardiomyopathy (NCCM) is explained by pathogenic variants in the same sarcomeric genes that are associated with hypertrophic (HCM) and dilated (DCM) cardiomyopathy. Pathogenic variants in the filamin C gene (FLNC) have been linked to HCM and DCM. We expand the spectrum of FLNC related cardiomyopathies by presenting two families with likely pathogenic FLNC variants showing familial segregation of NCCM and concurrent coarctation of the aorta and/or mitral valve abnormalities.

Predominant causes for newly diagnosed postpartum heart failure are preeclampsia and peripartum cardiomyopathy. Being an anatomical variant of Takotsubo syndrome (TTS) reverse TTS in this period is rare. We present a 36 year old patient, who had delivered triplets by cesarean section. Because of postpartum bleeding she was administered sulprostone. Later she was transferred to the Intensive Care Unit with sudden development of dyspnea, tachypnea and tachycardia. Clinical symptoms, laboratory findings and chest radiograph showed signs of acute heart failure. Transthoracic echocardiography (TTE) revealed reverse TTS with moderately reduced left ventricular ejection fraction (LVEF 39%). The patient stabilized with loop diuretic, angiotensine-converting enzyme inhibitors and beta-blockade. Breast-feeding was discouraged and bromocriptine administered. Left ventricular function normalized (LVEF 60%) within four weeks. TTS should be considered in patients with early postpartum development of heart failure. Rapid cardiac recompensation after the start of adequate therapy and complete resolution of clinical symptoms and TTE findings are typical for postpartum TTS.
新诊断产后心力衰竭的主要原因是先兆子痫和围产期心肌病。作为Takotsubo综合征(TTS)的解剖变异,逆行TTS在这一时期是罕见的。我们提出一个36岁的病人,谁已经分娩三胞胎剖宫产。由于产后出血,她服用了磺胺前列酮。后因突然出现呼吸困难、呼吸急促及心动过速转至加护病房。临床症状、实验室检查和胸片显示急性心力衰竭的迹象。经胸超声心动图(TTE)显示逆行TTS伴左室射血分数中度降低(LVEF 39%)。患者使用利尿剂、血管紧张素转换酶抑制剂和β -阻滞剂稳定病情。不鼓励母乳喂养,并给予溴隐亭。左心室功能在四周内恢复正常(LVEF 60%)。产后早期心力衰竭患者应考虑TTS。在开始适当的治疗和临床症状和TTE症状的完全解决后,心脏快速再代偿是产后TTS的典型特征。
