RESUMO

The rapidly increasing burden of hypertension is responsible for premature deaths from cardiovascular disease (CVD), renal disease, and stroke, with a tremendous public health and financial burden. Hypertension detection, treatment, and control vary worldwide; it is still low, particularly in low- and middle-income countries (LMICs). High blood pressure (BP) and CVD risk have a strong, linear, and independent association. They contribute to alarming numbers of all-cause and CVD deaths. A major culprit for increased hypertension is sympathetic activity, and further complications of hypertension are heart failure, ischemic heart disease (IHD), stroke, and renal failure. Now, antihypertensive interventions have emerged as a global public health priority to reduce BP-related morbidity and mortality. Calcium channel blockers (CCB) are highly effective vasodilators. and the most common drugs used for managing hypertension and CVD. Cilnidipine, with both L- and N-type calcium channel blocking activity, is a promising 4th generation CCB. It causes vasodilation via L-type calcium channel blockade and inhibits the sympathetic nervous system (SNS) via N-type calcium channel blockade. Cilnidipine, which acts as a dual L/N-type CCB, is linked to a reduced occurrence of pedal edema compared to amlodipine, which solely blocks L-type calcium channels. The antihypertensive properties of cilnidipine are very substantial, with low BP variability and long-acting properties. It is beneficial for hypertensive patients to deal with morning hypertension and for patients with abnormal nocturnal BP due to exaggerated sympathetic nerve activation. Besides its BP-lowering effect, it also exhibits organ protection via sympathetic nerve inhibition and renin-angiotensin-aldosterone system inhibition; it controls heart rate and proteinuria. Reno-protective, neuroprotective, and cardioprotective effects of cilnidipine have been well-documented and demonstrated.

RESUMO

INTRODUCTION: Diagnosis of acute coronary syndrome (ACS) is often challenging especially in presence of initial normal troponins and non-specific electrocardiogram. The index study aimed at determining the diagnostic value of strain echocardiography in patients with suspected ACS but with non-diagnostic electrocardiogram and echocardiography findings. METHODS: The study was conducted on 42 patients with suspected ACS and non-diagnostic electrocardiograms, normal quantitative troponin-T levels, and left ventricular function. All patients underwent conventional and 2D-strain echocardiography followed by coronary angiography, within 24 h of admission. Patients with regional wall motion abnormalities (RWMA), valvular heart disease, suspected myocarditis, and past coronary artery disease (CAD) were excluded. RESULTS: Amongst the global strains, the global circumferential strain (GCS) was significantly reduced (p = .014) amongst those with significant CAD on angiography as opposed to global longitudinal strain (GLS) which was similar in the two groups (p = .33). The GCS/GLS ratio was also significantly reduced in patients with significant CAD compared to those with normal/mild disease on coronary angiography (p = .025). Both the parameters had good accuracy in predicting significant CAD. GCS displayed a sensitivity of 80% and a specificity of 86% at an optimal cut-off 31.5% (AUROC: .93, 95% CI: .601-1.000; p = .03), and likewise GCS/GLS ratio had a sensitivity of 80% and a specificity and 86% at a cut-off of 1.89% (AUROC: .86, 95% CI: .592-1.000; p = .049). GLS and peak atrial longitudinal strain (PALS) did not differ significantly in patients with/without significant CAD (p = .32 and .58, respectively). CONCLUSION: GCS and GCS/GLS ratio provides incremental value in comparison to GLS, PALS, and tissue Doppler indices (E/e') in patients with suspected ACS and non-diagnostic electrocardiogram and troponins. GCS at cut-off of >31.5% and GCS/GLS ratio >1.89 can reliably exclude patients with significant CAD in this setting.

RESUMO

AIMS: The International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) trial prespecified an analysis to determine whether accounting for recurrent cardiovascular events in addition to first events modified understanding of the treatment effects. METHODS AND RESULTS: Patients with stable coronary artery disease (CAD) and moderate or severe ischaemia on stress testing were randomized to either initial invasive (INV) or initial conservative (CON) management. The primary outcome was a composite of cardiovascular death, myocardial infarction (MI), and hospitalization for unstable angina, heart failure, or cardiac arrest. The Ghosh-Lin method was used to estimate mean cumulative incidence of total events with death as a competing risk. The 5179 ISCHEMIA patients experienced 670 index events (318 INV, 352 CON) and 203 recurrent events (102 INV, 101 CON). A single primary event was observed in 9.8% of INV and 10.8% of CON patients while ≥2 primary events were observed in 2.5% and 2.8%, respectively. Patients with recurrent events were older; had more frequent hypertension, diabetes, prior MI, or cerebrovascular disease; and had more multivessel CAD. The average number of primary endpoint events per 100 patients over 4 years was 18.2 in INV [95% confidence interval (CI) 15.8-20.9] and 19.7 in CON (95% CI 17.5-22.2), difference -1.5 (95% CI -5.0 to 2.0, P = 0.398). Comparable results were obtained when all-cause death was substituted for cardiovascular death and when stroke was added as an event. CONCLUSIONS: In stable CAD patients with moderate or severe myocardial ischaemia enrolled in ISCHEMIA, an initial INV treatment strategy did not prevent either net recurrent events or net total events more effectively than an initial CON strategy.

RESUMO

BACKGROUND: The International Study of Comparative Health Effectiveness with Medical and Invasive Approaches trial demonstrated no overall difference in the composite primary endpoint and the secondary endpoints of cardiovascular (CV) death/myocardial infarction or all-cause mortality between an initial invasive or conservative strategy among participants with chronic coronary disease and moderate or severe myocardial ischemia. Detailed cause-specific death analyses have not been reported. METHODS: We compared overall and cause-specific death rates by treatment group using Cox models with adjustment for pre-specified baseline covariates. Cause of death was adjudicated by an independent Clinical Events Committee as CV, non-CV, and undetermined. We evaluated the association of risk factors and treatment strategy with cause of death. RESULTS: Four-year cumulative incidence rates for CV death were similar between invasive and conservative strategies (2.6% vs 3.0%; hazard ratio [HR] 0.98; 95% CI [0.70-1.38]), but non-CV death rates were higher in the invasive strategy (3.3% vs 2.1%; HR 1.45 [1.00-2.09]). Overall, 13% of deaths were attributed to undetermined causes (38/289). Fewer undetermined deaths (0.6% vs 1.3%; HR 0.48 [0.24-0.95]) and more malignancy deaths (2.0% vs 0.8%; HR 2.11 [1.23-3.60]) occurred in the invasive strategy than in the conservative strategy. CONCLUSIONS: In International Study of Comparative Health Effectiveness with Medical and Invasive Approaches, all-cause and CV death rates were similar between treatment strategies. The observation of fewer undetermined deaths and more malignancy deaths in the invasive strategy remains unexplained. These findings should be interpreted with caution in the context of prior studies and the overall trial results.

RESUMO

A 22-year male presented with complaints of dyspnea. Multimodality imaging revealed a polypoidal right atrial mass with submassive pulmonary embolism. The patient underwent urgent surgery. The pathological examination confirmed it as cardiac myxoma. Cardiac myxoma, a most common primary cardiac tumor, is commonly found in the left atrium. The right atrium is an uncommon site and the usual mode of presentation is the tumor or thrombus embolization to the pulmonary circulation.

RESUMO

BACKGROUND AND AIM: Coronary artery disease (CAD) is one of the predominant types of cardiovascular disease (CVD). The aim of present study was to study various factors that are causing difference in prevalence of coronary risk factors among siblings. MATERIALS AND METHODS: This cross-sectional study was conducted in Dayanand Medical College and Hospital, among the healthy individuals (not known CAD) attending regular health care outpatient department (OPD) and their siblings over a period of 1½ years. All individuals coming for regular health checkup (not known CAD) of age more than 30 years or above and their siblings (with or without known CAD). RESULTS: This was a cross-sectional study, conducted among 100 pairs of healthy siblings (not known cases of CAD) who came for health checkup at health center of Dayanand Medical College and Hospital, a tertiary care hospital in North India. Prevalence of obesity was more in siblings living in urban area than their counter siblings living in rural area, but it was statistically insignificant. Six had impaired fasting blood sugar (FBS) and two were diabetic. Among their siblings living in urban area, 21 were nondiabetic, 10 had impaired FBS, and seven were diabetic. This correlation was statistically significant with p-value of 0.02. Among the CAD negative, out of 23 subjects, two subjects (9.0%) had heavy stress level, while remaining four subjects (17.0%) and 17 subjects (74.0%) had light and moderate stress levels, respectively. Among the CAD negative, out of 23 subjects, 10 subjects (43.0%) had high stress level, while remaining zero subject (0%) and 13 subjects (57.0%) had light and moderate stress levels, respectively. Significant results were obtained while comparing the CAD findings of subjects divided on the basis of stress level. CONCLUSION: In our study, among siblings (CAD positive and CAD negative), significant results were obtained for residence, socioeconomic class, physical activity, stress levels, smoking, waist-to-hip ratio (WHR), and diabetes, that is, all these factors have correlation in increasing CAD among siblings.

RESUMO

Background and Aims: N95 mask being an essential element of personal protective equipment to be worn by health-care workers (HCWs) may lead to adverse effects and physiological stress as HCWs have to wear it for prolonged hours. Therefore, we planned to conduct a study in our intensive care unit staff to look for the effects of N95 masks on their health as well as to plan recommendations to ease them. Material and Methods: We conducted this study on our intensive care unit nursing staff and HCWs. We noted their oxygen saturation and heart rate at baseline as well as after 1 h, 2 h, 3 h, and 6 h of duty along with their subjective sensations. Institutional ethical clearance for the same was taken. Collected data were entered in MS Excel database and analyzed using SPSS version 20.0. Fisher's Z test was applied for comparing proportion and analysis of variance for comparing two means. Results: One hundred and nine HCWs participated in this, out of which 93 (85.3%) were females and 16 (14.7%) were males. Eighty-four (77.1%) participants were below 40 years. Twenty-three participants (21.1%) were overweight and 37 (33.9%) were obese. There was no significant drop in saturation and rise in heart rate during these hours. Conclusions: On comparing subjective sensations of HCWs, our study found that feeling of uneasiness was found more in less than 40 years age group as compared to more than 40 years. N95 masks were found to have no impact on cardiovascular system and do not lead to hypoxia while working routinely even for prolonged hours.

RESUMO

CONTEXT: Multiple observational studies have reported an inverse relationship between 25-hydroxyvitamin D concentrations (25(OH)D) and type 2 diabetes (T2D). However, the results of short- and long-term interventional trials concerning the relationship between 25(OH)D and T2D risk have been inconsistent. OBJECTIVES AND METHODS: To evaluate the causal role of reduced blood 25(OH)D in T2D, here we have performed a bidirectional Mendelian randomization study using 59,890 individuals (5,862 T2D cases and 54,028 controls) from European and Asian Indian ancestries. We used six known SNPs, including three T2D SNPs and three vitamin D pathway SNPs, as a genetic instrument to evaluate the causality and direction of the association between T2D and circulating 25(OH)D concentration. RESULTS: Results of the combined meta-analysis of eight participating studies showed that a composite score of three T2D SNPs would significantly increase T2D risk by an odds ratio (OR) of 1.24, p = 1.82 × 10-32; Z score 11.86, which, however, had no significant association with 25(OH)D status (Beta -0.02nmol/L ± SE 0.01nmol/L; p = 0.83; Z score -0.21). Likewise, the genetically instrumented composite score of 25(OH)D lowering alleles significantly decreased 25(OH)D concentrations (-2.1nmol/L ± SE 0.1nmol/L, p = 7.92 × 10-78; Z score -18.68) but was not associated with increased risk for T2D (OR 1.00, p = 0.12; Z score 1.54). However, using 25(OH)D synthesis SNP (DHCR7; rs12785878) as an individual genetic instrument, a per allele reduction of 25(OH)D concentration (-4.2nmol/L ± SE 0.3nmol/L) was predicted to increase T2D risk by 5%, p = 0.004; Z score 2.84. This effect, however, was not seen in other 25(OH)D SNPs (GC rs2282679, CYP2R1 rs12794714) when used as an individual instrument. CONCLUSION: Our new data on this bidirectional Mendelian randomization study suggests that genetically instrumented T2D risk does not cause changes in 25(OH)D levels. However, genetically regulated 25(OH)D deficiency due to vitamin D synthesis gene (DHCR7) may influence the risk of T2D.

RESUMO

BACKGROUND: Hypertriglyceridemia has emerged as a critical coronary artery disease (CAD) risk factor. Rare loss-of-function (LoF) variants in apolipoprotein C-III have been reported to reduce triglycerides (TG) and are cardioprotective in American Indians and Europeans. However, there is a lack of data in other Europeans and non-Europeans. Also, whether genetically increased plasma TG due to ApoC-III is causally associated with increased CAD risk is still unclear and inconsistent. The objectives of this study were to verify the cardioprotective role of earlier reported six LoF variants of APOC3 in South Asians and other multi-ethnic cohorts and to evaluate the causal association of TG raising common variants for increasing CAD risk. METHODS: We performed gene-centric and Mendelian randomization analyses and evaluated the role of genetic variation encompassing APOC3 for affecting circulating TG and the risk for developing CAD. RESULTS: One rare LoF variant (rs138326449) with a 37% reduction in TG was associated with lowered risk for CAD in Europeans (p = 0.007), but we could not confirm this association in Asian Indians (p = 0.641). Our data could not validate the cardioprotective role of other five LoF variants analysed. A common variant rs5128 in the APOC3 was strongly associated with elevated TG levels showing a p-value 2.8 × 10- 424. Measures of plasma ApoC-III in a small subset of Sikhs revealed a 37% increase in ApoC-III concentrations among homozygous mutant carriers than the wild-type carriers of rs5128. A genetically instrumented per 1SD increment of plasma TG level of 15 mg/dL would cause a mild increase (3%) in the risk for CAD (p = 0.042). CONCLUSIONS: Our results highlight the challenges of inclusion of rare variant information in clinical risk assessment and the generalizability of implementation of ApoC-III inhibition for treating atherosclerotic disease. More studies would be needed to confirm whether genetically raised TG and ApoC-III concentrations would increase CAD risk.

RESUMO

OBJECTIVE: Recent studies have shown that lower serum chloride is associated with diuretic resistance and increased mortality in heart failure. Impact of lower admission chloride on duration of stay in acute decompensated heart failure (ADHF) has not been studied previously. METHODS: In this retrospective analysis, we studied the effect of admission serum chloride on the duration of hospital stay in patients admitted with ADHF. A total of 167 patients were studied. Serum chloride levels were divided into tertiles - <96 meq/L (tertile 1), 96-101 meq/L (tertile 2), and >101 meq/L (tertile 3) based on the distribution of serum chloride levels in our patients. RESULTS: The median lengths of hospital stay in tertiles 1, 2, and 3 were 8(Interquartile range :6 -11), 7 (Interquartile range :5 -10.50), and 6 days(Interquartile range :4.25 - 8), respectively (p = 0.011). Admission serum chloride levels were inversely associated with duration of stay (R2 linear = 0.074, p = 0.001). On multiple linear regression analysis, serum chloride remained independent predictor of increased hospital stay (p=0.003) while association with serum sodium was not significant (p=0.07). 1 unit increase in chloride level was associated with 1.3% (p=0.003) decrease in hospital stay (95% CI: 2.2% to 0.5%). CONCLUSION: This retrospective analysis suggests that admission serum chloride levels are independently and inversely associated with increased duration of stay. This is independent of admission sodium levels. Thus serum chloride, rather than sodium, is an important poor prognostic marker in heart failure patients.

RESUMO

BACKGROUND: Asians are predisposed to a lean heart failure (HF) phenotype. Data on the 'obesity paradox', reported in Western populations, are scarce in Asia and have only utilised the traditional classification of body mass index (BMI). We aimed to investigate the association between obesity (defined by BMI and abdominal measures) and HF outcomes in Asia. METHODS AND FINDINGS: Utilising the Asian Sudden Cardiac Death in Heart Failure (ASIAN-HF) registry (11 Asian regions including Taiwan, Hong Kong, China, India, Malaysia, Thailand, Singapore, Indonesia, Philippines, Japan, and Korea; 46 centres with enrolment between 1 October 2012 and 6 October 2016), we prospectively examined 5,964 patients with symptomatic HF (mean age 61.3 ± 13.3 years, 26% women, mean BMI 25.3 ± 5.3 kg/m2, 16% with HF with preserved ejection fraction [HFpEF; ejection fraction ≥ 50%]), among whom 2,051 also had waist-to-height ratio (WHtR) measurements (mean age 60.8 ± 12.9 years, 24% women, mean BMI 25.0 ± 5.2 kg/m2, 7% HFpEF). Patients were categorised by BMI quartiles or WHtR quartiles or 4 combined groups of BMI (low, <24.5 kg/m2 [lean], or high, ≥24.5 kg/m2 [obese]) and WHtR (low, <0.55 [thin], or high, ≥0.55 [fat]). Cox proportional hazards models were used to examine a 1-year composite outcome (HF hospitalisation or mortality). Across BMI quartiles, higher BMI was associated with lower risk of the composite outcome (ptrend < 0.001). Contrastingly, higher WHtR was associated with higher risk of the composite outcome. Individuals in the lean-fat group, with low BMI and high WHtR (13.9%), were more likely to be women (35.4%) and to be from low-income countries (47.7%) (predominantly in South/Southeast Asia), and had higher prevalence of diabetes (46%), worse quality of life scores (63.3 ± 24.2), and a higher rate of the composite outcome (51/232; 22%), compared to the other groups (p < 0.05 for all). Following multivariable adjustment, the lean-fat group had higher adjusted risk of the composite outcome (hazard ratio 1.93, 95% CI 1.17-3.18, p = 0.01), compared to the obese-thin group, with high BMI and low WHtR. Results were consistent across both HF subtypes (HFpEF and HF with reduced ejection fraction [HFrEF]; pinteraction = 0.355). Selection bias and residual confounding are potential limitations of such multinational observational registries. CONCLUSIONS: In this cohort of Asian patients with HF, the 'obesity paradox' is observed only when defined using BMI, with WHtR showing the opposite association with the composite outcome. Lean-fat patients, with high WHtR and low BMI, have the worst outcomes. A direct correlation between high WHtR and the composite outcome is apparent in both HFpEF and HFrEF.

RESUMO

The burden of atherosclerotic cardiovascular (CV) disease is alarmingly high and increasing in our country. Dyslipidemia is one of the major modifiable risk factors, and INTERHEART study showed that dyslipidemia had the highest population attributable risk for myocardial infarction. In the management of dyslipidemia, low-density lipoprotein cholesterol (LDL-C) is the primary therapeutic target. In addition to therapeutic lifestyle changes, statins and ezetimibe effectively lower LDL-C and consequently improve CV outcomes. However, there are situations where these drugs fall short of achieving the target or they may not be well tolerated.

RESUMO

Left atrial appendage aneurysm (LAA AN) is a rare disease entity, which can be congenital or acquired in nature. We report an adult patient with LAA AN presenting with anginal chest pain in whom live/real time three-dimensional transthoracic echocardiography (3DTTE) provided incremental value over the two-dimensional (2D) technique in providing a more comprehensive assessment of the lesion. A literature review of the salient features of LAA AN is also provided in a tabular form.

RESUMO

BACKGROUND: Informed consent is an integral part of clinical practice. Improper informed consent can lead to mistrust between doctors and patients as well as medico-legal issues. Awareness and knowledge of various aspects of consent is essential in present day medical practice. METHODS: A paper and web-based survey was undertaken to evaluate knowledge about informed consent among doctors. A law and a medical student generated a list of questions based upon available case laws and legislations which were further validated by experts. 500 doctors undertook the survey and of these 457 completed the survey of 18 questions. Both univariate and multivariate models were used to analyze responses. RESULTS: 413 complete questionnaires were included in the analysis. The proportion of respondents furnishing correct responses varied between 49.6% and 93.7%. There were 9 questions for which, over 25% respondents provided inappropriate responses. The questions included those enquiring whether initial consent for diagnostic or therapeutic procedures could apply to extended procedures or surgery and who was capable of giving consent for different procedures. There were significant differences of knowledge between residents and consultants for few questions. The physicians fared worse than surgeons and anesthetists although the difference was not statistically significant. CONCLUSION: Significant knowledge gaps were identified. There were deficiencies in providing correct response particularly in practical scenarios. There is a need to include knowledge about different aspects of informed consent in the medical curriculum.

RESUMO

Cardiovascular (CV) diseases are a major cause of premature death and disability. Non-communicable diseases (NCD) are responsible for 52% of mortality amongst Indians, of these CV diseases are responsible for 66% of NCD mortality in India. We not only need widespread primary preventive strategy but also need effective secondary prevention protocols to reduce this. Secondary prevention in patients who already had myocardial infarction (MI) or revascularization is of utmost importance to reduce mortality, cardiac events and improve quality of life. Lifestyle changes and medical therapy have a very important role in secondary prevention of CVD. Optimal control of hypertension, diabetes mellitus and dyslipidemia plays a critical role in secondary prevention. Statins are one of the most commonly used drugs in secondary prevention as a part of medical therapy. Effective LDL reduction, more patients achieving LDL goals, reduction in intima thickness, improvement in endothelial dysfunction, reduction in inflammatory markers are considered to be surrogate markers of reduced risk with statins. Rosuvastatin is one of the two most commonly used statins. It is a potent, effective and safe HMG-COA reductase inhibitor. Data related to secondary prevention is limited with rosuvastatin. Most of the clinical evidences with rosuvastatin have shown more effective LDL reduction than other statins. More number of patients achieve LDL goals and reduction in intima thickness. This article attempts to explore data on role of rosuvastatin for secondary prevention.

RESUMO

Torsades de pointes with prolonged QTc interval is a form of ventricular tachycardia. Many predisposing factors have been identified and hypocalcemia is among the rare ones. Our case illustrates that though rare, hypocalcemia might manifest as torsades de pointes with prolongation of QTc interval. Early diagnosis and management of dyselectrolytemia can prevent these patients from catastrophic torsades de pointes.

RESUMO

BACKGROUND: Current international guidelines on dyslipidemia are not concordant on various aspects of management. Also, there are no uniformly accepted Indian guidelines. We, therefore, performed a physician survey to understand lipid management practices in India. METHODS: An anonymous survey questionnaire was administered to gauge physicians' self-reported behavior regarding lipid management aspects. Results were expressed in terms of percentages based on the number of responses obtained. RESULTS: A total of 404 physicians participated in the survey. Eighty-eight percent respondents ordered a lipid profile before starting statin therapy, and 80% preferred to set lipid targets, though the tools used for calculating cardiovascular risk varied. Atorvastatin was preferred over rosuvastatin in primary prevention (72.9 vs. 32.4%), secondary prevention (54.6 vs. 46.7%), diabetic patients (56.3 vs. 40.3%) and post-ACS (78.3 vs. 34%). High-intensity statins were preferred by 73.7% of respondents in post-ACS cases. Fifty percent doctors chose not to use a statin in diabetic patients, irrespective of their LDL-C levels. The most preferred drug option for managing atherogenic dyslipidemia and moderate hypertriglyceridemia was statin-fibrate combination (55.1%) and fibrates (35.4%), respectively. Sixty-three percent doctors preferred to prescribe statins in patients with moderately high LDL-C and normal triglycerides, without CHD or CHD risk equivalents. Around 28% of doctors preferred not to use pharmacotherapy for managing isolated low HDL. Of the participants, 73% used fibrates in ≤20% of their dyslipidemic patients, with fenofibrate being the most preferred (90.5%). Ezetimibe was mainly used in patients with uncontrolled LDL-C despite statin therapy (52.4% respondents). Most preferred approaches to manage statin intolerance included reducing statin dose (39%) and stopping and restarting statins at a lower dose (34.5%). Fifty-two percent of doctors chose not to alter pre-existing therapy in patients who had LDL-C levels at goal but elevated non-HDL-C levels. CONCLUSION: This is the first survey in India that provides useful insights into Indian physicians' self-reported perspectives on managing dyslipidemia in routine clinical practice. Despite concordance with the currently available guidelines in certain aspects, there is incongruence in managing specific dyslipidemia problems. Further continuing medical education and the development of evidence-based, India-specific lipid guidelines can help reduce some of these differences.
