Background A vegetarian diet (VD) may reduce future cardiovascular risk in patients with ischemic heart disease. Methods and Results A randomized crossover study was conducted in subjects with ischemic heart disease, assigned to 4‐week intervention periods of isocaloric VD and meat diet (MD) with individually designed diet plans, separated by a 4‐week washout period. The primary outcome was difference in oxidized low‐density lipoprotein cholesterol (LDL‐C) between diets. Secondary outcomes were differences in cardiometabolic risk factors, quality of life, gut microbiota, fecal short‐chain and branched‐chain fatty acids, and plasma metabolome. Of 150 eligible patients, 31 (21%) agreed to participate, and 27 (87%) participants completed the study. Mean oxidized LDL‐C (−2.73 U/L), total cholesterol (−5.03 mg/dL), LDL‐C (−3.87 mg/dL), and body weight (−0.67 kg) were significantly lower with the VD than with the MD. Differences between VD and MD were observed in the relative abundance of several microbe genera within the families Ruminococcaceae, Lachnospiraceae, and Akkermansiaceae. Plasma metabolites, including l ‐carnitine, acylcarnitine metabolites, and phospholipids, differed in subjects consuming VD and MD. The effect on oxidized LDL‐C in response to the VD was associated with a baseline gut microbiota composition dominated by several genera of Ruminococcaceae. Conclusions The VD in conjunction with optimal medical therapy reduced levels of oxidized LDL‐C, improved cardiometabolic risk factors, and altered the relative abundance of gut microbes and plasma metabolites in patients with ischemic heart disease. Our results suggest that composition of the gut microbiota at baseline may be related to the reduction of oxidized LDL‐C observed with the VD.

Background: Ischemic heart disease (IHD) is one of the leading causes of mortality in Pakistan. With advancement in research, multiple causes have contributed in development of web of causation of this public health issue. The objective of this study was to assess gender differences in risk factors associated with ischemic heart disease in patients presenting at the biggest cardiology hospital of Lahore. Patients and methods: A comparative cross-sectional study was carried out in Punjab Institute of Cardiology, Lahore from January to August, 2018 on a sample of 296 diagnosed patients of IHD, through non-probability consecutive sampling technique. Data was collected on pretested questionnaire. The data was analyzed using SPSS version 22. Chi-Square test of significance was applied and a p-value ≤0.05 was considered statistically significant. Results: The mean age of participants was 45±12 years with predominance of male patients (71.3%). Frequency of risk factors for IHD included increase body mass index (83.8%), hypertension (61%), insufficient physical activity (43%), diabetes (38.5%) and smoking (23%). Increase serum cholesterol was reported in 95% and triglycerides in 99% of the participants. Gender difference was significant with females residing in urban population (p=0.054) and exercise routine (p=0.034). Males showed high tendency of IHD with smoking pattern (p<0.001) contrary to presence of diabetes in females (p=0.05), hypertension (p=0.054), BMI (p=0.0379) and stressful event in life (p=0.002). Males showed regular intake of medicines (p =0.045) after diagnosis as compared to female population. Conclusion: There is more frequency of ischemic heart disease in males as compared to females. Significant association was observed with residence in urban area, presence of diabetes, hypertension, high BMI and stressful event in life in occurrence of ischemic heart disease in female population.

Left bundle branch block is not a benign pathology, and its presence requires the identification of a pathological substrate, such as ischemic heart disease. Left bundle branch block appears to be more commonly associated with normal coronary arteries, especially in women. The objectives of our study were to describe the particularities of left bundle branch block in women compared to men with ischemic heart disease. Result: We included seventy patients with left bundle branch block and ischemic heart disease, with a mean age of 67.01 ± 8.89 years. There were no differences in the profile of risk factors, except for smoking and uric acid. The ventricular depolarization (QRS) duration was longer in men than women (136.86 ± 8.32 vs. 132.57 ± 9.19 msec; p = 0.018) and also men were observed to have larger left ventricular diameters. Left bundle branch block duration was directly associated with ventricular diameters and indirectly associated with left ventricular ejection fraction value, especially in women (R = −0.52, p = 0.0012 vs. R = −0.50, p = 0.002). In angiography, 80% of women had normal epicardial arteries compared with 65.7% of men; all these patients presented with microvascular dysfunction. Conclusion: The differences between the sexes were not so obvious in terms of the presence of risk factors; instead, there were differences in electrocardiographic, echocardiographic, and angiographic aspects. Left bundle branch block appears to be a marker of microvascular angina and systolic dysfunction, especially in women.

Abstract Background In clinical setting, ischemic heart disease is a challenging problem in hemodialysis (HD) population. Coronary flow reserve (CFR) measured by 13 ammonia positron emitting tomography (13NH3PET) is an established and reliable modality for detecting coronary artery disease. Furthermore, some prior studies show CFR is an important and independent predictor for cardiovascular event and mortality. On the other hand, HD patients with malnutrition status have poor prognosis. We have reported about the relationship between cardiovascular events and geriatric nutrition risk index (GNRI). Now, we wonder the predictability of combination of CFR and GNRI. Methods and result We collected 438 consecutive HD patients who received 13NH3PET in our hospital suspected for ischemic heart disease. 29 patients were excluded due to undergoing coronary revascularization within 60 days, 103 patients were excluded due to incomplete database. In total, 306 HD patients were classified into 4 group according the median value of CFR (1.99) and GNRI (97.73); Low CFR Low GNRI group (n=77), High CFR and Low GNRI group (n=76), Low CFR High GNRI group (n=78) and High CFR High GNRI group (n=75). We collected their follow up data up to 1544 days (median 833 days) about all-cause mortality and cardiovascular (CV) mortality. Surprisingly, there is no mortality event in High CFR High GNRI group. We analyzed about all-cause mortality, CV mortality. Kaplan-Meyer analysis shows there are statistically intergroup differences in each (all-cause mortality; log rank p&lt;0.01, CV mortality; log rank p=0.02). Furthermore, we calculated area under the curve (AUC) analysis, net reclassification improvement (NRI) and integrated discrimination improvement (IDI)m adding GNRI and CFR on conventional risk factors. There are intergroup differences for all-cause mortality in AUC [conventional risk factors, +GNRI, +GNRI+CFR; 0.70, 0.72 (p=0.29), 0.79 (p&lt;0.01)], NRI [+GNRI; 0.32 (p=0.04), +GNRI+CFR 0.82 (p&lt;0.01)] and IDI [+GNRI; 0.01 (p=0.05), +GNRI+CFR 0.09 (p&lt;0.01)]. Conclusion HD patients with low CFR and malnutrition status has statistically significant poorer prognosis comparing HD patients with high CFR and without malnutrition status. Adding combination of GNRI and CFR on conventional risk factors improves the predictability of HD population's prognosis. Funding Acknowledgement Type of funding source: None

Background: Greater lactation duration has been associated with lower incidence of the metabolic syndrome, and self-reported type 2 diabetes and heart disease in women later in life. Two retrospective studies reported higher carotid artery intima-media thickness among parous women who never or inconsistently breastfed, but no clear association with duration. However, lactation history was recalled many years later and heart disease risk factors were not measured before pregnancy. We hypothesized that lactation duration has a graded inverse association with subclinical atherosclerosis in women during mid-life independent of pre-pregnancy cardiometabolic risk factors. Methods: We examined 846 women (46% Black), aged 18-30 years at enrollment in 1985-1986 (baseline) in the biracial Coronary Artery Risk Development in Young Adults (CARDIA) study. Women included delivered 1 or more live births from 1986-2005, had no history of heart disease or diabetes before pregnancies, and had maximum common carotid intima media thickness (ccIMT, mm) measured in 2005-2006 at ages 38-50 years. Lactation duration was recalled within 1 to 4 years of delivery. We categorized women into four lactation groups according to cumulative duration for all post-baseline births; 0-<1 month (n=262), 1-<6 months (n=210), 6-10 months (n=169) and >10 months (n=205). Multiple linear regression models estimated mean ccIMT (95% CI) among lactation categories adjusted for pre-pregnancy cardiometabolic risk factors [BMI, systolic blood pressure (SBP), HDL-C, HOMA-IR], parity, socio-demographics (age, race, education), and smoking. We also assessed weight gain and change in SBP as mediators of the lactation and ccIMT association. Results: Increasing lactation duration showed a graded inverse association with mean ccIMT; differences between >10 months vs. 0<1 month groups ranged from -0.062 from the unadjusted model (p<0.001) and -0.029 from adjusted models (p=0.046) that included pre-pregnancy risk factors and other covariates. Weight gain and SBP change during the 20-year follow up slightly attenuated (~10%) the ccIMT-association with increased lactation duration. Conclusions: Greater lactation duration is associated with lower mean ccIMT independent of cardiometabolic risk factors measured before pregnancy, parity, socio-demographics and smoking. Lactation may have lasting favorable effects on cardiometabolic risk factors for heart disease.
