Abstract
BACKGROUND Coronary heart disease (CHD) is the leading cause of death worldwide. Many single-nucleotide polymorphisms (SNPs) are found to be related to the risk of CHD in previous studies. This study investigated whether polymorphism of SMARCA4 gene is associated with CHD. MATERIALS AND METHODS Genotypes at five CHD-relevant SNPs were determined in 456 cases of incident CHD and 685 unaffected controls in Chinese Han population using χ2 test, genetic model analysis and haplotype analysis. We also analysis the differences in continuous variables among the subjects with three genotypes of related genes were assessed using the ANOVA. RESULTS We identified two susceptibility SNPs in the SMARCA4 gene that were potentially associated with a decreased risk of CHD. We identified rs11879293 (OR, 0.74; 95% CI, 0.59-0.96; P = 0.012) and rs12232780 (OR, 0.70; 95% CI, 0.54-0.90; P = 0.005) were associated with a decreased risk of CHD risk under the log-additive model adjusted by gender and age. Meanwhile, we also found that significant differences in glucose concentrations with rs11879293 and rs1122608 different genotype. Serum LDL-C and HDL-C were seen among the 3 genotypes of rs12232780 exist differences. CONCLUSION This study provides an evidence for polymorphism of SMARCA4 gene associated with CHD development in Chinese Han population.

Clinical profile and 30-day outcome of women with acute coronary syndrome as a first manifestation of ischemic heart disease: A single-center observational study. Indian Heart J 2016; 68:164-8. [PMID: 27133325 DOI: 10.1016/j.ihj.2015.08.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2015] [Revised: 07/22/2015] [Accepted: 08/04/2015] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Gender disparity, with respect to women receiving less medical therapy, undergoing fewer invasive procedures, and experiencing worse outcome than men, has been noted in various observational and randomized trials, though guidelines on acute coronary syndrome (ACS) are gender-neutral. Indian data with focus on women with ACS are lacking. AIM This study was undertaken to give us an insight on the clinical presentation, risk factors, and in-hospital outcome of ACS in women and at 30 days. MATERIALS AND METHODS 133 successive cases of women presenting with ACS, who met the inclusion criteria between 2012 and 2014, were included. Cases were grouped into ST elevation myocardial infarction (STEMI), non ST elevation myocardial infarction (NSTEMI), and unstable angina (UA). RESULTS AND CONCLUSION The mean age was 64.4±11 years. The mean BMI was 23.64±3.23kg/m(2). Diabetes was present in 58.3% in NSTEMI, 65.1% in STEMI, and 57.1% in UA group. Hypertension was found in 75% of NSTEMI, 60.2% of STEMI, and 71.4% of UA group. Severe MR was found in 11.1% of NSTEMI and 3.6% of STEMI patients. 8.3% of NSTEMI and 15.7% of STEMI patients presented in Killips class IV. Single vessel disease was most commonly found across the spectrum of ACS. 68.7% patients in STEMI group underwent primary angioplasty. 5.6% of NSTEMI and 7.2% in STEMI group had contrast-induced nephropathy (CIN). All deaths were noted in STEMI group with eight in-hospital deaths and three during 30-day follow-up period. Killips class III and IV and higher grace score (>150) were predictors of in-hospital mortality. Chronic kidney disease, ischemic mitral regurgitation, LV clot, and in-hospital cardiac arrest were associated with higher risk.

Abstract
Myocardial infarction (MI) leads to substantial morbidity and mortality around the world. Accurate assessment of myocardial viability is essential to assist therapies and improve patient outcomes. (131)I-hypericin dicarboxylic acid ((131)I-HDA) was synthesized and evaluated as a potential diagnostic agent for earlier assessment of myocardium viability compared to its preceding counterpart (131)I-hypericin ((131)I-Hyp) with strong hydrophobic property, long plasma half-life, and high uptake in mononuclear phagocyte system (MPS). Herein, HDA was synthesized and characterized, and self-aggregation constant Kα was analyzed by spectrophotometry. Plasma half-life was determined in healthy rats by γ-counting. (131)I-HDA and (131)I-Hyp were prepared with iodogen as oxidant. In vitro necrosis avidity of (131)I-HDA and (131)I-Hyp was evaluated in necrotic cells induced by hyperthermia. Biodistribution was determined in rat models of induced necrosis using γ-counting, autoradiography, and histopathology. Earlier imaging of necrotic myocardium to assess myocardial viability was performed in rat models of reperfused myocardium infarction using single photon emission computed tomography/computed tomography (SPECT/CT). As a result, the self-aggregation constant Kα of HDA was lower than that of Hyp (105602 vs 194644, p < 0.01). (131)I-HDA displayed a shorter blood half-life compared with (131)I-Hyp (9.21 vs 31.20 h, p < 0.01). The necrotic-viable ratio in cells was higher with (131)I-HDA relative to that with (131)I-Hyp (5.48 vs 4.63, p < 0.05). (131)I-HDA showed a higher necrotic-viable myocardium ratio (7.32 vs 3.20, p < 0.01), necrotic myocardium-blood ratio (3.34 vs 1.74, p < 0.05), and necrotic myocardium-lung ratio (3.09 vs 0.61, p < 0.01) compared with (131)I-Hyp. (131)I-HDA achieved imaging of necrotic myocardium at 6 h postinjection (p.i.) with SPECT/CT, earlier than what (131)I-Hyp did. Therefore, (131)I-HDA may serve as a promising necrosis-avid diagnostic agent for earlier imaging of necrotic myocardium compared with (131)I-Hyp. This may support further development of radiopharmaceuticals ((123)I and (99m)Tc) based on HDA for SPECT/CT of necrotic myocardium.

Abstract
AIMS Metabolic syndrome has been associated with increased risk of cardiovascular disease. We aimed to determine the effectiveness of a community-based screening program in identifying cardiovascular risk factors in healthy young South Asian population. MATERIALS AND METHODS Between 2006 and 2011, 3314 patients of all ages were recruited as a part of a prospective cohort study investigating cardiovascular risk in South Asians. We analyzed 1537 patients between the ages of 18 and 40. Demographic and baseline characteristics including baseline laboratory markers and blood pressures were obtained at initial visit. RESULTS The total cohort of 1537 patients was 66.5% male, and the mean age was 35±5 years. Among participants who denied a history of hypercholesterolemia, 62% had elevated LDL-C (>100 mg/dL), and 8% had markedly elevated LDL-C (>160 mg/dL). Overall, diabetes was present in 4%, hypertension was present in 12% and hyperlipidemia was present in 46%. Low HDL-C (50% of men, 52% of women) and elevated triglycerides (44% of men, 18% of women) were the most prevalent components of metabolic syndrome. Metabolic syndrome was present in 14% of men and 8% of women and one-third (30%) of men and one-fifth (19%) of women had at least two component risk factors. CONCLUSIONS This is the largest study to date assessing effectiveness of a community based screening program aiming to identify cardiovascular risk in young South Asians. We note significant modifiable risk at a young age. Such community based interventions can be effective at detecting and managing risk factors early in this vulnerable population.

Moderate intense physical activity depends on selected Metabolic Equivalent of Task (MET) cut-off and type of data analysis. PLoS One 2013; 8:e84365. [PMID: 24376804 PMCID: PMC3869841 DOI: 10.1371/journal.pone.0084365] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2013] [Accepted: 11/22/2013] [Indexed: 11/19/2022] Open
Abstract
Background Accelerometry data are frequently analyzed without considering whether moderate-to-vigorous physical activities (MVPA) were performed in bouts of >10 minutes as defined in most physical activity guidelines. We aimed i) to quantify MVPA by using different commonly-applied physical activity guidelines, ii) to investigate the effect of bouts versus non-bouts analysis, and iii) to propose and validate a MVPA non-bouts cut-point to classify (in-) active subjects. Methods Healthy subjects (n=110;62±6yrs) and patients with Chronic Obstructive Pulmonary Disease (COPD) (n=113;62±5yrs) wore an activity monitor for 7 days. Three Metabolic Equivalent of Task (MET) cut-offs and one individual target (50% VO2 reserve) were used to define MVPA. First, all minutes of MVPA were summed up (NON-BOUTS). Secondly, only minutes performed in bouts of >10 minutes continuous activity were counted (BOUTS). Receiver operating characteristic (ROC) curve analyses were used to propose and (cross-) validate new MVPA non-bout cut-points based on the criterion of 30 minutes MVPA per day (BOUTS). Likelihood ratios (sensitivity/[1-specificity]) were used to express the association between the proposed MVPA non-bout target and the MVPA bout target of 30 min*day-1. Results MVPA was variable across physical activity guidelines with lowest values for age-specific cut-offs. Selecting a METs cut-point corresponding to 50% VO2 reserve revealed no differences in MVPA between groups. MVPA’s analyzed in BOUTS in healthy subjects were 2 to 4 fold lower than NON-BOUTS analyses and this was even 3 to 12 fold lower in COPD. The MVPA non-bouts cut-point of 80 min*day-1 using a 3 METs MVPA threshold delivered positive likelihood ratios of 5.1[1.5-19.6] (healthy subjects) and 2.3[1.6-3.3] (COPD). Conclusion MVPA varies upon the selected physical activity guideline/targets and bouts versus non-bouts analysis. Accelerometry measured MVPA non-bouts target of 80 min*day-1, using a 3 METs MVPA threshold, is associated to the commonly-used MVPA bout target of 30 min*day-1.
