Objectives: This study aimed to assess the association of left ventricular end-diastolic pressure (LVEDP) with the extent and severity of coronary artery diseases (CAD) in individuals undergoing primary percutaneous coronary intervention (PCI) at a tertiary care cardiac center in Karachi, Pakistan. Methodology: This descriptive cross-sectional study included consecutive patients undergoing primary PCI. LVEDP was assessed with the help of a multipurpose catheter. The Association of LVEDP with the extent and severity of CAD was assessed. Results: LVEDP was stratified as ≤15 mmHg, 15-25 mmHg, and >25 mmHg. Out of 498 patients included in this study, 76.3% (380) were male, and mean age was 53.7±11.7 years. Mean LVEDP was 19.35±6.17 mmHg. Burden of diseases was found to be significantly associated with LVEDP level (p<0.001) with mean LVEDP of 18.5±5.6 mmHg, 19.5±6 mmHg, and 21.4±7.2 mmHg among patients with single, two and three-vessel disease respectively. Proportion of three-vessel diseases was 15.5% (37/239), 22.5% (47/209), and 36% (18/50) at LVEDP ≤15 mmHg, 15-25 mmHg, and >25 mmHg, respectively. Conclusion: There was a strong inverse relationship between LVEDP and initial TIMI flow grade (p=0.013) and a positive relationship between LVEDP and total length of the lesion (p=0.002). In conclusion, increased LVEDP was found to be associated with increased burden and extent of coronary artery disease, poor initial TIMI flow grade, and longer length of lesion.
目的:本研究旨在评估在巴基斯坦卡拉奇一家三级保健心脏中心接受初级经皮冠状动脉介入治疗(PCI)的患者左室舒张末期压(LVEDP)与冠状动脉疾病(CAD)的程度和严重程度之间的关系。方法:这项描述性横断面研究纳入了连续接受首次PCI治疗的患者。在多用途导管的帮助下评估LVEDP。评估LVEDP与冠心病程度和严重程度的关系。结果:LVEDP分为≤15mmhg、15- 25mmhg和> 25mmhg。纳入研究的498例患者中,76.3%(380例)为男性,平均年龄53.7±11.7岁。平均LVEDP为19.35±6.17 mmHg。疾病负担与LVEDP水平显著相关(p<0.001),单支、双支和三支血管疾病患者的平均LVEDP分别为18.5±5.6 mmHg、19.5±6 mmHg和21.4±7.2 mmHg。LVEDP≤15 mmHg、15-25 mmHg和>25 mmHg时,三支血管病变的比例分别为15.5%(37/239)、22.5%(47/209)和36%(18/50)。结论:LVEDP与TIMI初始血流等级呈强负相关(p=0.013),与病变总长度呈正相关(p=0.002)。综上所述,LVEDP增加与冠状动脉疾病负担和范围增加、初始TIMI血流等级差和病变长度延长有关。

Systemic blood pressure, recorded by various parameters, always shows variation. This is known as ‘variability’, an entity not assessed routinely. Research has shown greater prognostic importance of it than routine parameters. Various intrinsic and extrinsic factors modulate it. Depending on the interval of successive readings, blood pressure variability is of five types, with different non-invasive methods utilized for recording. It is calculated by various statistical parameters, the most common being standard deviation, but average real variability is the most accurate and easily applied. Clinical evidence is increasing rapidly, indicating variability as a prognostic marker for stroke, ischemic heart disease, renal failure, cognitive dysfunction, heart failure, and mortality. Therapeutic measures for the control of variability have also been forwarded. The paucity of clinical application of blood pressure variability is the stimulus to narrate this review, especially for physicians managing hypertensive patients.
通过各种参数记录的全身血压总是显示出变化。这就是所谓的“变异性”,一个没有常规评估的实体。研究表明,它比常规参数具有更大的预后重要性。各种内在和外在因素调节着它。根据连续读数的间隔,血压变异性分为五种类型,采用不同的非侵入性方法进行记录。它是由各种统计参数计算出来的,最常见的是标准偏差,但平均实际变异性是最准确和容易应用的。临床证据正在迅速增加,表明变异性是中风、缺血性心脏病、肾衰竭、认知功能障碍、心力衰竭和死亡率的预后标志。还提出了控制变异的治疗措施。缺乏临床应用的血压变异性是刺激叙述这篇综述,特别是对医生管理高血压患者。

Objectives: This study was aimed to explore the association of ABO gene variants with coronary artery disease. Methodology: This was a case-control study. Cases and controls were individuals with greater than 50% and less than 30% stenosis, respectively. One hundred thirty-eight samples were obtained, with 69 cases and 69 controls. The operator completed a proforma regarding demographics, medical history, and blood group. The bench work included blood typing, followed by blood genotyping by DNA extraction, PCR, and then Sanger's sequencing. The single nucleotide polymorphisms (SNPs) selected for the ABO gene were rs8176746 and rs8176719. Results: The results show that 68.1% of the participants were male cases, compared to 49.27% controls. The frequency of patients belonging to the old age group (60-75 years) was 65.21% in cases and 34.78% in controls. A+ was the most prevalent group in cases, with 33.33%, followed by 24.6% B+, 23.2% O+, and 4.3% AB+. Patients with Rh-ve groups were rare. On the contrary, 33.33% of patients were O+ in controls. A chi-square test showed that the A+ blood group was significantly associated with CAD, having a p-value of 0.01. Although blood genotypes did not show a significant p-value, the odds of having genotype AA was 1.35 times higher in cases compared to the controls. Conclusion: This study shows that the A+ group is significantly associated with CAD. The data obtained through Sanger’s sequencing determined the genetic variants of blood groups, but no statistically significant association was found between them and CAD.
目的:本研究旨在探讨ABO基因变异与冠心病的关系。方法学:本研究为病例对照研究。病例和对照组分别是狭窄大于50%和小于30%的个体。共获得138份样本,其中病例69例,对照69例。操作者完成了一份关于人口统计、病史和血型的形式报告。工作台工作包括血型,然后通过DNA提取、PCR进行血液基因分型,然后进行桑格测序。ABO基因的单核苷酸多态性为rs8176746和rs8176719。结果:男性病例占68.1%,对照组为49.27%。老年组(60 ~ 75岁)占65.21%,对照组占34.78%。以A+型为主,占33.33%,其次为B+型,占24.6%,O+型占23.2%,AB+型占4.3%。Rh-ve组患者少见。相反,对照组中33.33%的患者为0 +。卡方检验显示,A+血型与CAD有显著相关性,p值为0.01。虽然血液基因型没有显示出显著的p值,但与对照组相比,AA基因型的几率高1.35倍。结论:本研究显示A+组与冠心病有显著相关性。通过Sanger测序获得的数据确定了血型的遗传变异,但没有发现它们与CAD之间有统计学意义的关联。

Objectives: The study aimed at assessing the outcome of pulmonary vein isolation (PVI) using second-generation cryoballoon, Arctic Front Advance, Medtronic (CB-Adv) as a rhythm control strategy for drug-resistant paroxysmal atrial fibrillation (PAF) in a cardiac tertiary care center of Pakistan.Methodology: Fifty patients had PVI with CB-Adv for symptomatic drug-resistant PAF at the National Institute of Cardiovascular Diseases, Karachi, Pakistan, during 2017-2022. Patients were followed-up in the clinic on the 1st, 3rd, and 6th month after the ablation. Twenty-four hours of Holter monitoring of electrocardiogram was obtained on each visit. We conducted a retrospective chart review after approval from the ethical review committee. We collected all the patients' demographic and clinical data, procedural results, and reports of Holter monitoring. The primary outcome was successful PVI and freedom from atrial tachyarrhythmia (Ata) on a 6-month follow-up.Results: We enrolled all 50 patients (34 male, 68%; mean age 55.14 ± 7.94 years) treated with PVI using CB-Adv. The mean duration of symptoms was 30.28 ± 13.48 months. PVI with CB-Adv was found to be curative in 49 patients (98%). Following the procedure, pericardial effusion was found in one patient (2%), whereas one patient (2%) had a retroperitoneal hematoma. On a six-month follow-up, only one patient (2%) had a recurrence of Ata, which was PAF.Conclusion: Our experience of PVI with CB-Adv has shown a high success rate of the procedure for rhythm control in patients who have PAF, which is resistant to antiarrhythmic drugs (AADs).

Objectives: Acute kidney injury (AKI) is frequently present co-morbid condition in patients admitted with acute heart failure (AHF). This study aimed to determine the frequency of in-hospital mortality in AHF patients presenting with AKI.Methodology: This descriptive case series of AHF patients with AKI was conducted at a tertiary care cardiac hospital in Karachi, Pakistan. In accordance with the “Risk, Injury, Failure, Loss, and End‐Stage Renal Disease (RIFLE) scale," the AKI was defined as a 3.0‐fold increase in serum creatinine (sCr) or sCr > 4.0 mg/dL within 48 hours. All the patients were followed for seven days in order to assess the outcome variable, i.e., in-hospital mortality.Results: A total of 149 patients were included with a mean age of 59.7 ± 11.03 years, and 80 (53.7%) patients were male. Hypertensive patients were 59.1% (88) of the sample, and 38.9% (58) of the patients were diabetics. In-hospital mortality was found in 11 (7.4%) patients. The mortality rate was 14.1% vs. 2.4%; p=0.008 among patients >60 and 40 to 60 years, respectively. The mortality rate was 12.5% vs. 3.5%; p=0.038 among diabetic and non-diabetic patients. Similarly, the mortality rate was 11.4% vs. 1.6%, p=0.022, among hypertensive and non-hypertensive patients.Conclusion: It is to conclude that AKI in AHF patients carries a significant burden of in-hospital mortality. The mortality rate was significantly higher for patients with older age and co-morbid conditions such as hypertension and diabetes.
目的:急性肾损伤(AKI)是急性心力衰竭(AHF)患者常见的合并症。本研究旨在确定伴有AKI的AHF患者的住院死亡率。方法:在巴基斯坦卡拉奇的一家三级心脏病医院进行了这一AHF AKI患者的描述性病例系列。根据“风险、损伤、失败、损失和终末期肾病(RIFLE)量表”,AKI被定义为血清肌酐(sCr)增加3.0倍或48小时内sCr>4.0 mg/dL。对所有患者进行了7天的随访,以评估结果变量,即住院死亡率。结果:共纳入149例患者,平均年龄59.7±11.03岁,其中80例(53.7%)为男性。高血压患者占样本的59.1%(88),糖尿病患者占38.9%(58)。11名(7.4%)患者在医院内死亡。死亡率分别为14.1%和2.4%;60岁以上和40至60岁患者的p分别为0.008。死亡率分别为12.5%和3.5%;在糖尿病和非糖尿病患者中p=0.038。同样,高血压和非高血压患者的死亡率分别为11.4%和1.6%,p=0.022。结论:AHF患者的AKI对住院死亡率有显著影响。年龄较大且合并高血压和糖尿病等疾病的患者死亡率明显较高。

Syncope is a frequently encountered condition in the emergency room, with vagal syncope being the most prevalent form. However, overlapping symptoms can pose diagnostic challenges when distinguishing between vagal syncope and symptomatic sinus node dysfunction. A comprehensive history and careful evaluation of hemodynamics and electrocardiogram findings are crucial for accurate differentiation. Vagal syncope is typically associated with an upright posture, and supine syncope is considered atypical. In this case report, we describe an intriguing instance of supine vagal syncope, highlighting the importance of correct diagnosis to avoid unnecessary pacemaker implantation.
晕厥是急诊室常见的疾病,其中迷走神经性晕厥最为常见。然而,在区分迷走神经性晕厥和症状性窦房结功能障碍时,重叠的症状可能会给诊断带来挑战。全面的病史和仔细评估血液动力学和心电图表现对于准确鉴别至关重要。迷走神经性晕厥通常与直立姿势有关,仰卧性晕厥被认为是非典型的。在这个病例报告中,我们描述了一个有趣的仰卧迷走神经性晕厥的例子,强调了正确诊断以避免不必要的起搏器植入的重要性。

Vagal syncope is typically associated with an upright posture, and supine syncope is considered atypical. In this case report, we describe an intriguing instance of supine vagal syncope, highlighting the importance of correct diagnosis to avoid unnecessary pacemaker implantation.","PeriodicalId":42273,"journal":{"name":"Pakistan Heart Journal","volume":" ","pages":""},"PeriodicalIF":0.1,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46083304","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}

Hypertension poses a significant global burden due to low adherence to antihypertensive medications. Hypertension treatment aims to bring blood pressure within physiological ranges and reduce the risk of cardiovascular disease and organ damage associated with high blood pressure. It is estimated that around 1.13 billion people have hypertension, accounting for 13% of all fatalities worldwide. The World Health Organization aims to reduce this number by 25% by 2025 compared to the baseline year of 2010.1,2 Despite the availability of effective antihypertensive medications and decreased main risk factors, achieving optimal blood pressure control remains challenging for various reasons, including apparent drug resistance and poor compliance.3,4 One of the contributing factors to poor blood pressure control is the difficulty in predicting which antihypertensive medication will be most effective for a specific patient. An individualized approach to hypertension treatment, considering risk factors, pharmacokinetic properties, genetic phenotypes, and other patient-specific characteristics, holds promise.Pharmacogenomics and other 'omics' technologies can help identify genetic signals indicative of a favorable or unfavorable response to specific antihypertensive drugs. By conducting research in this field, we can better understand how to optimize blood pressure response using different classes of antihypertensive medications.4 Pharmacogenetics studies the genetic basis of medication response variability, particularly the influence of genetic factors on drug metabolism. In recent years, simple nucleotide polymorphisms (SNPs) have emerged as the primary genetic variation markers. High-throughput genotyping approaches can detect SNPs, which are widespread throughout the genome, often involve substitutions, and rarely result in mutations. SNPs in drug-metabolizing enzymes have been reliable indicators for dose-related treatment decisions.Genetic studies conducted over the past two decades have identified various genetic polymorphisms associated with hypertension, including changes in the number of tandem repeats, microsatellites, single nucleotide polymorphisms (SNPs), and insertions/deletions (I/D). These studies have also revealed significant inter-individual variability in responsiveness to antihypertensive medications, highlighting the importance of pharmacogenomic research and the potential for individualized pharmacological therapy. Genetic factors may contribute to a 30-50% increase in blood pressure.5 A comprehensive approach is required to advance personalized medicine, incorporating data and insights from genomic, genetic, and proteomic sciences. This applies to both approved medications and therapeutic candidates in various stages of clinical trials. Personalized medicine aims to administer the right drug to the right patient at the right time and dosage. By embracing this concept, we can significantly improve hypertension treatment outcomes.6Th
由于对抗高血压药物的依从性低,高血压在全球范围内造成了巨大负担。高血压治疗旨在将血压控制在生理范围内,降低与高血压相关的心血管疾病和器官损伤的风险。据估计,约有11.3亿人患有高血压,占全球死亡人数的13%。世界卫生组织的目标是到2025年,与2010年的基准年相比,将这一数字减少25%。1,2尽管有有效的降压药物,主要风险因素也有所减少,但由于各种原因,实现最佳血压控制仍然具有挑战性,包括明显的耐药性和依从性差。3,4导致血压控制不佳的因素之一是难以预测哪种降压药物对特定患者最有效。考虑到风险因素、药代动力学特性、遗传表型和其他患者特定特征,高血压治疗的个性化方法有望实现。药物基因组学和其他“组学”技术可以帮助识别指示对特定降压药物的有利或不利反应的遗传信号。通过在该领域进行研究,我们可以更好地了解如何使用不同类别的降压药物来优化血压反应。4药物遗传学研究药物反应变异的遗传基础,特别是遗传因素对药物代谢的影响。近年来,单核苷酸多态性(SNPs)已成为主要的遗传变异标记。高通量基因分型方法可以检测SNPs,SNPs在整个基因组中广泛存在,通常涉及替换,很少导致突变。药物代谢酶中的SNPs一直是剂量相关治疗决策的可靠指标。在过去二十年中进行的遗传学研究已经确定了与高血压相关的各种遗传多态性,包括串联重复序列、微卫星、单核苷酸多态性(SNPs)和插入/缺失(I/D)数量的变化。这些研究还揭示了抗高血压药物反应性的显著个体间差异,突出了药物基因组研究的重要性和个体化药物治疗的潜力。遗传因素可能导致血压升高30-50%。5需要一种综合的方法来推进个性化医学,结合基因组、遗传和蛋白质组科学的数据和见解。这适用于已批准的药物和临床试验各个阶段的候选治疗药物。个性化医疗旨在在正确的时间和剂量给正确的患者服用正确的药物。通过接受这一概念,我们可以显著改善高血压治疗结果。6高血压个性化治疗的目标是确定降低患者血压的最有效药物。相反,一种相反的观点认为,个体化治疗有助于消除药物不良反应和使用无效药物的风险。依从性问题进一步强调了改进高血压治疗的必要性。因此,根据个体患者特征定制医疗方法和治疗计划的个性化医学,7抗高血压药物基因组学研究旨在通过确定影响抗高血压反应变异性的遗传因素来改善接受治疗的高血压患者的心血管疾病(CVD)结果。尽管这些遗传变量约占人群血压变异的50%,但造成这种变异的很大一部分的特定基因尚未确定。这种情况的复杂性归因于不同基因座的等位基因通过各种途径的影响,以及环境因素对血压表型表现的影响。有证据支持这样一种假设,即遗传学可能会导致人们对降压药物反应的个体差异。通过整合遗传信息,药物基因组学可以为个性化治疗方法提供见解。然而,还需要进一步的研究来揭示所涉及的特定基因和途径。提高我们对降压反应变异性的遗传基础的理解,对于优化高血压治疗具有巨大潜力。在药物基因组学的推动下,个性化医学可以彻底改变高血压的管理并提高患者的预后。 2022年;55(2):200-1.Shahbaz SAZ,Nazar MS,Umar A,Tariq MA,ul Haq I,Junaid M.普通人群高血压意识评估

Objectives: Right ventricular infraction has prognostic significance in the setting of acute “inferior wall myocardial infarction (IWMI)”, this research is intended to determine the frequency of “right ventricular infarction (RVI)” in patients with acute IWMI.Methodology: This descriptive cross-sectional study took place at a tertiary care hospital in Peshawar, Pakistan. The study included consecutive patients who were diagnosed with acute IWMI. The presence of RVI was determined based on specific ECG findings showing >1.0mm ST segment elevation on right-sided chest leads.Results: In a sample of 150 patients, 87 (58%) were male. The average age of the patients was 61 ± 10.7 years. Among the patients, 111 (74%) had hypertension, 64 (42.7%) were diabetic, and 45 (30%) were smokers. A body mass index (BMI) exceeding 25 kg/m2 was observed in 83 (55.3%) patients. RVI was observed in 62 (41.3%) of the patients. The occurrence of RVI did not show statistically significant differences between males and females (41.4% vs. 41.3%; p=0.989), hypertensive and non-hypertensive individuals (41.4% vs. 41.0%; p=0.964), diabetics and non-diabetics (42.2% vs. 40.7%; p=0.855), smokers and non-smokers (42.2% vs. 41.0%; p=0.885), and patients with BMI ≤25 kg/m2 and >25 kg/m2 (41.8% vs. 41.0%; p=0.920), respectively.Conclusion: Based on the research findings, it can be concluded that RVI is a relatively common occurrence in patients with acute IWMI, as it was observed in more than 40% of the patients studied. However, no statistically significant association exists between RVI and various demographic and clinical factors.

Objectives: Rheumatic heart disease remains a significant problem in developing countries, with mitral stenosis (MS) being a frequent manifestation. The objective of this study was to compare transthoracic echocardiographic (TTE) findings of mitral valve calcification with fluoroscopy.Methodology: This cross-sectional study was conducted at the department of adult cardiology, National Institute of Cardiovascular Diseases (NICVD) Karachi. All patients were candidates for percutaneous mitral balloon valvuloplasty (PMBV), aged between 15 to 65 years of either gender. Patients who underwent TTE were subjected to fluoroscopy before PMBV. The Kappa coefficient was calculated to assess the agreement between the two modalities. An appropriate t-test or Mann-Whitney U test was applied, and a p-value ≤ 0.05 was taken as the criterion for statistical significance.Results: A total of 160 patients were included in this study with a mean age of 34.01± 12.32 years, 119 (74.4%) were between 18 to 40 years of age, and 108 (67.5%) were female. Calcification was observed in 40.6% (65) on echocardiography and 50.6% (81) of the patients on fluoroscopy. A substantial agreement was observed between the two modalities with a Kappa coefficient of 0.75 for the detection of calcification.Conclusion: No significant difference was observed in the detection of calcification on echocardiography and fluoroscopy, along with a substantial agreement between the two modalities for the detection of calcification. Echocardiography can be a less invasive alternative to fluoroscopy for the detection of calcification before PMBV.

Non-alcoholic fatty liver disease (NAFLD) is a prevalent condition that affects a significant portion of the global population and imposes a heavy clinical and economic burden. Recent studies have provided substantial evidence linking NAFLD to cardiac electrical abnormalities, including atrial and ventricular arrhythmias, heart blocks, conduction delays, and ECG changes. These cardiac electrical disturbances play a significant role in cardiac diseases that are the leading cause of death in NAFLD patients. This paper aims to provide an update on the proposed mechanisms underlying arrhythmogenesis in NAFLD and summarize the latest research findings in this field. Managing NAFLD requires a comprehensive approach that includes treating the underlying liver condition and regular ECG monitoring to detect and address any potential cardiac complications. Meta-analyses are recommended for future research further to elucidate the association between NAFLD and cardiac arrhythmias. Understanding and effectively managing the cardiac implications of NAFLD will contribute to improved patient care and outcomes.
非酒精性脂肪肝(NAFLD)是一种普遍存在的疾病,影响着全球很大一部分人口,并带来了沉重的临床和经济负担。最近的研究提供了大量证据,将NAFLD与心电异常联系起来,包括心房和心室心律失常、心脏传导阻滞、传导延迟和心电图变化。这些心脏电紊乱在心脏疾病中起着重要作用,而心脏疾病是NAFLD患者死亡的主要原因。本文旨在提供NAFLD心律失常发生机制的最新进展,并总结该领域的最新研究结果。管理NAFLD需要一种全面的方法,包括治疗潜在的肝脏疾病和定期心电图监测,以检测和解决任何潜在的心脏并发症。建议对未来的研究进行荟萃分析,以进一步阐明NAFLD与心律失常之间的关系。了解并有效管理NAFLD的心脏影响将有助于改善患者护理和结果。
