Evidence for genetic polymophisms may contribute to the dependence on sex and age differences in biochemical phenotypes, clinical manifestation, severity and success in medical treatment of coronary artery disease (CAD) comes from a variety of studies. Two genetic polymorphisms, L55M and Q192R, in the human antioxidant system paraoxonase 1 gene (PON1) have been shown to be associated with increased risk of CAD. The aim of recent study was to investigate a possible association between polymorphic variants of PON1 and CAD in patients of different age and sex. The group of patients with CAD (323 men and 71 women) and the group of healthy (114 men and 84 women) randomly sampled from St Petersburg were investigated clinically, biochemically and genetically. We found out the genotype L55M and Q192R frequencies in the group of patients with CAD were different depending on sex and age (p = 0,057, p = 0,007). In women with CAD the frequency of 55MM genotype (ОR = 2,1311, 95 % CI 1,14-3,98) was significantly higher and the frequency of 192QR genotype (ОR = 0,59, 95 % CI 0,39-0,89) was significantly lower than in men with CAD who survived myocardial infarction (MI) under the age of 45. Our results suggest that both PON1 polymorphisms play the role in risk of CAD. Furthermore, PON1 polymorphisms act in various ways in patients of different age and sex.

Abstract Background Patients with diabetes without obstructive coronary artery disease (CAD) by coronary angiography (CAG) have a risk of myocardial infarction (MI) similar to that of non-diabetes patients without CAD. Their cardiovascular risk compared to the general population is unknown. Purpose We examined the 10-year risks of myocardial infarction (MI), ischemic stroke, and death in diabetes patients without CAD after CAG compared to the general population. Methods We included all diabetes patients without obstructive CAD examined by CAG from 2003–2016 in Western Denmark and an age and sex matched comparison group, sampled from the general population in Western Denmark without previous history of coronary heart disease. Outcomes were MI, ischemic stroke, and death. The 10-year cumulative incidences were estimated. Adjusted hazard ratios (HRs) were estimated by stratified Cox regression using the general population as the reference group. Results We identified 5,760 diabetes patients without obstructive CAD and 29,139 individuals from the general population. Median follow-up was 7 years with 25% of participants followed for up to 10 years. Diabetes patients without obstructive CAD had an almost similar 10-year risk of MI (3.2% vs 2.9%, adjusted HR 0.91, 95% CI 0.70–1.17, Figure) compared to the general population cohort. Diabetes patients had an increased risk of ischemic stroke (5.2% vs 2.2%, adjusted HR 1.88, 95% CI 1.48–2.39), and death (29.7% vs 17.9%, adjusted HR 1.41, 95% CI 1.29–1.54). The duration of diabetes was associated with increased cardiovascular risk. Conclusions Absence of obstructive CAD by CAG in patients with diabetes ensures a low MI risk similar to the general population, but diabetes patients still have an increased risk of ischemic stroke and all-cause death despite absence of CAD.

Background: Little is known about the association between coronary artery disease (CAD) and the risk of heart failure (HF) after myocardial infarction (MI), and whether it differs by reduced (HFrEF) or preserved (HFpEF) ejection fraction (EF) has yet to be determined. Subjects and Methods: Olmsted County, Minnesota residents (n=1,924; mean age, 64 years; 66% male) with first MI diagnosed in 1990-2010 and no prior HF were followed through 2013. Framingham Heart Study criteria were used to define HF, which was further classified according to EF (applying a 50% cutoff). The extent of angiographic CAD was defined at index MI according to the number of major epicardial coronary arteries with ≥50% lumen diameter obstruction. Fine & Gray and Cox proportional hazards regression models were used to assess the association of CAD categories with incidence of HF, and multiple imputation methodology was applied to account for the 19% with missing EF data. Results: During a mean (SD) follow-up of 6.7 (5.9) years, 594 patients developed HF. Adjusted for age and sex, with death considered a competing risk, the cumulative incidence rates of HF among patients with 1- (n=581), 2- (n=622), and 3-vessel disease (n=721) were 11.2%, 14.6% and 20.5% at 30 days; and 18.1%, 22.3% and 29.4% at 5 years after MI, respectively. The increased risk of HF with greater number of occluded vessels was only modestly attenuated after further adjustment for patient and MI characteristics, and did not differ materially by EF (Table). Conclusions: The extent of angiographic CAD expressed by the number of diseased vessels is independently associated with HF incidence after MI. The association is evident promptly after MI and applies to both HFrEF and HFpEF.

Abstract Diabetes is known to be a major cardiovascular risk factor associated with significantly increased morbidity and mortality and particularly increased risk of major cardiac events especially myocardial infarction as a manifestation of highly incident coronary artery disease (CAD).This can lead to decreased life expectation and life quality. Major cause for myocardial infarction is plaque rupture. Prevalence of obstructive and non-obstructive plaques is increased in diabetic patients. Background and Objectives The prevalence of coronary heart disease in diabetic patients compared to non- diabetics and evaluating the composition of the plaque in diseased individuals in both groups by usage of multislice computed tomography (MSCT) angiography . Subjects and Methods A total of 80 consecutive MSCT angiography examinations were performed between August 2017 and June 2018. Of these, the patients were evaluated for the presence and type of atherosclerotic plaque and severity of luminal narrowing. Results Eighty (40 in the diabetic group and 40 in the non-diabetic group) patients underwent MSCT angiography with DM prevalence of 0.212 (95% Cl for AOR 0.056 -1.896). Among them, 20 patients (50 %) in the diabetic group and 14 patients (35 %) in the non-diabetic group had +ve coronary heart disease, 33.3 % had significant and moderately significant coronary narrowing on diabetic group and 31.3 % in non-diabetic group on MSCT angiography. Diabetic patients had more soft plaque compared with non-diabetic patients. Conclusion DM is not an independent factor for the disease occurrence in coronary artery disease but is a dependent factor in the association of other risk factors such as smoking ,hypertension and dyslipidemia.

Enzymes CYP4A11 and CYP4F2 are involved in biosynthesis of vasoactive 20-hydroxyeicosatetraenoic acid and may contribute to pathogenesis of coronary artery disease (CAD). We investigated whether polymorphisms of theCYP4A11andCYP4F2genes are associated with the risk of CAD in Russian population. DNA samples from 1323 unrelated subjects (637 angiographically confirmed CAD patients and 686 age- and sex-matched healthy individuals) were genotyped for polymorphisms rs3890011, rs9332978, and rs9333029 ofCYP4A11and rs3093098 and rs1558139 ofCYP4F2by using the Mass-ARRAY 4 system. SNPs rs3890011 and rs9332978 ofCYP4A11were associated with increased risk of CAD in women: OR = 1.26, 95% CI: 1.02–1.57,P=0.004, andQ=0.01and OR = 1.45, 95% CI: 1.13–1.87,P=0.004, andQ=0.01, respectively. Haplotype G-C-A ofCYP4A11was associated with increased risk of CAD (adjusted OR = 1.41, 95% CI: 1.12–1.78, andP=0.0036). Epistatic interactions were found between rs9332978 ofCYP4A11and rs1558139 ofCYP4F2(Pinteraction=0.025). In silico analysis allowed identifying that SNP rs9332978 is located at a binding site for multiple transcription factors; many of them are known to regulate the pathways involved in the pathogenesis of CAD. This is the first study in Europeans that reported association between polymorphism rs9332978 ofCYP4A11and susceptibility to coronary artery disease.

Background The initial presentation to coronary angiography and extent of coronary artery disease (CAD) vary greatly among patients, from ischemia with no obstructive CAD to myocardial infarction with 3‐vessel disease. Pain tolerance has been suggested as a potential mechanism for the variation in presentation of CAD. We aimed to investigate the association between pain tolerance, coronary angiography, CAD, and death. Methods and Results We identified 9576 participants in the Tromsø Study (2007–2008) who completed the cold‐pressor pain test, and had no prior history of CAD. The median follow‐up time was 10.4 years. We applied Cox‐regression models with age as time‐scale to calculate hazard ratios (HR). More women than men aborted the cold pressor test (39% versus 23%). Participants with low pain tolerance had 19% increased risk of coronary angiography (HR, 1.19 [95% CI, 1.03–1.38]) and 22% increased risk of obstructive CAD (HR, 1.22 [95% CI, 1.01–1.47]) adjusted by age as time‐scale and sex. Among women who underwent coronary angiography, low pain tolerance was associated with 54% increased risk of obstructive CAD (HR, 1.54 [95% CI, 1.09–2.18]) compared with high pain tolerance. There was no association between pain tolerance and nonobstructive CAD or clinical presentation to coronary angiography (ie, stable angina, unstable angina, and myocardial infarction). Participants with low pain tolerance had increased risk of mortality after adjustment for CAD and cardiovascular risk factors (HR, 1.40 [95% CI, 1.19–1.64]). Conclusions Low cold pressor pain tolerance is associated with a higher risk of coronary angiography and death.

Background: Myocardial bridging (MB) is frequently seen on coronary CT angiography (CCTA). However, there has been conflicting data on the prognostic value of MB. The aim of this analysis is to determine the prognostic value of MB in patients without obstructive coronary artery disease (CAD) (<50 diameter stenosis). Methods: We included patients with no known prior coronary artery disease (CAD) who underwent CCTA for various clincial reasons. Patients with obstructive CAD on CCTA were excluded. The study cohort was followed for all cause mortality or myocardial infarction (MI) (median follow-up 1.7 years). Group comparisons were made between patients with patients with or without MB. Results: A total of 715 patients were included in this analysis of which 68 patients had MB (10%). 73% of the bridges were in the mid LAD and 22% had bridging in the distal LAD. 48% of the study cohort had normal coronaries, while 52% had evidence of non obstructive CAD. There were no differences in the baseline characteristics, symptomatic status or prevalence of non obstructive CAD between the two groups (all p>0.5). After a median follow-up duration of 1.7 years, 23 patients died and 10 patients experienced myocardial infarction. There were no statistically significant differences in the rate of death/MI between the two groups (figure). Using multivariable Cox regression, the presence of MB was not associated with increased risk for death/MI (Adjusted HR 0.4, 95% confidence interval 0.1 -2.8, p=0.34) Conclusions: In patients with non-obstructive CAD, MB is not associated with increased risk for all cause death or MI.

Abstract Background: Growth differentiation factor 15 (GDF-15), a stress responsive cytokine, belongs to transforming growth factor β (TGF-β) cytokine superfamily. Some evidence support that it’s involved in inflammation, coagulation, oxidative stress, endothelial dysfunction, and hemostasis. However, it’s still controversial whether GDF-15 directly contributes to the morbidity and mortality of patients suffered with cardiovascular disease (CVD). Besides prospective cohort study and randomized controlled trial, Mendelian randomization (MR) is a genetic epidemiological method that exploits genetic variants as unbiased proxies for modifiable to determine the causal relationships between exposures and health outcomes. Herein, we introduced a two-sample MR approach to evaluate the causal relationships of circulating GDF-15 levels with major CVDs incidence.Methods: Genetic instruments and summary statistics for two-sample MR analysis were obtained from 5 independent large genome-wide association studies (GWAS) to investigate the causal correlation between circulating GDF-15 levels and 9 CVDs, respectively. Conventional inverse variance weighted (IVW) method was adopted to evaluate the causality of GDF-15 with different outcomes; weighted median and MR egger were used for sensitivity analyses.Results: Among 9 SNPs identified from 5 GWASs in 2.6 million individuals, 5 SNPs (rs1227731, rs3195944, rs17725099, rs888663, rs749451) coming from chromosome 19 and containing the PGPEP1 and GDF-15 genes were employed. Based on the instruments, circulating GDF-15 levels significantly linked to the increased risk of cardioembolic stroke, atrial fibrillation, coronary artery disease and myocardial infarction. However, no significant causal association was observed for circulating GDF-15 levels with the incidence of any ischemic stroke, large-artery atherosclerotic stroke, small vessel stroke, heart failure and nonischemic cardiomyopathy.Conclusions: The MR study provides with genetic evidence for the causal relationship of circulating GDF-15 levels with the increased risk of cardioembolic stroke, atrial fibrillation, coronary artery disease and myocardial infarction, but not any ischemic stroke, large-artery atherosclerotic stroke, small vessel stroke, heart failure and nonischemic cardiomyopathy. It indicates that GDF-15 might be a promising biomarker or potential therapeutic target for some CVDs.
