Risk prediction tools cannot identify most individuals at high coronary artery disease (CAD) risk. Oxidized low-density lipoproteins (oxLDLs) and microRNAs are actively involved in atherosclerosis. Our aim was to examine the association of CAD and oxLDLs-induced microRNAs, and to assess the microRNAs predictive capacity of future CAD events. Human endothelial and vascular smooth muscle cells were treated with oxidized/native low-density lipoproteins, and microRNA expression was analyzed. Differentially expressed and CAD-related miRNAs were examined in serum samples from (1) a case-control study with 476 myocardial infarction (MI) patients and 487 controls, and (2) a case-cohort study with 105 incident CAD cases and 455 randomly-selected cohort participants. MicroRNA expression was analyzed with custom OpenArray plates, log rank tests and Cox regression models. Twenty-one microRNAs, two previously undescribed (hsa-miR-193b-5p and hsa-miR-1229-5p), were up- or down-regulated upon cell treatment with oxLDLs. One of the 21, hsa-miR-122-5p, was also upregulated in MI cases (fold change = 4.85). Of the 28 CAD-related microRNAs tested, 11 were upregulated in MI cases-1 previously undescribed (hsa-miR-16-5p)-, and 1/11 was also associated with CAD incidence (adjusted hazard ratio = 0.55 (0.35–0.88)) and improved CAD risk reclassification, hsa-miR-143-3p. We identified 2 novel microRNAs modulated by oxLDLs in endothelial cells, 1 novel microRNA upregulated in AMI cases compared to controls, and one circulating microRNA that improved CAD risk classification.

AbstractAimsCurrent risk prediction tools are not accurate enough to identify most individuals at high coronary risk. On the other hand, oxidized low-density lipoproteins (ox-LDLs) and miRNAs are actively involved in atherosclerosis. Our aim was to examine the association of ox-LDL-induced miRNAs with coronary artery disease (CAD), and to assess their predictive capacity of future CAD.Methods and resultsHuman endothelial and vascular smooth muscle cells were treated with oxidized or native LDLs (nLDL), and their miRNA expression was measured with the miRNA 4.0 array, and analyzed with moderated t-tests. Differently expressed miRNAs and others known to be associated with CAD, were examined in serum samples of 500 acute myocardial infarction (AMI) patients and 500 healthy controls, and baseline serum of 117 incident CAD cases and c 485 randomly-selected cohort participants (case-cohort). Both were developed within the REGICOR AMI Registry and population cohorts from Girona. miRNAs expression in serum was measured with custom OpenArray plates, and analyzed with fold change (age and sex-paired case-control) and survival models (case-cohort). Improvement in discrimination and reclassification by miRNAs was assessed. Twenty-one miRNAs were up- or down-regulated with ox-LDL in cell cultures. One of them, 1 (has-miR-122-5p, fold change=4.85) was upregulated in AMI cases. Of the 28 known CAD-associated miRNAs, 11 were upregulated in AMI cases, and 1 (hsa-miR-143-3p, hazard ratio=0.56 [0.38-0.82]) was associated with CAD incidence and improved reclassification.ConclusionWe identified 2 novel miRNAs associated with ox-LDLs (hsa-miR-193b-5p and hsa-miR-1229-5p), and 1 miRNA that improved reclassification of healthy individuals (hsa-miR-143-3p).

Background and Aims: The prevalence of cardiovascular diseases (CVD) are on the increase worldwide and more in the developing countries. Coronary artery disease (CAD) constitutes the major brunt of CVD. Despite the increasing morbidity and mortality, Bangladesh has a few published data on CAD in rural population. This study addressed the prevalence of CAD and its risk factors in rural population of Bangladesh.Study methods: Sixteen villages were purposively selected in a rural area. A population census was conducted in the selected area. The census yielded eligible participants, who reached at least eighteen years of age. Those who willingly consented to participate were enlisted. Each participant was interviewed regarding CAD risk (age, sex, social class, occupation, illness, family history). Anthropometry (height, weight, waist- and hip-girth) was recorded. Resting blood pressure (BP) was measured. Blood sample was collected for fasting blood glucose (FBG), total cholesterol (Chol), triglycerides (Tg), low density lipoproteins (LDL), very low density lipoproteins (VLDL) and high density (HDL). All participants having FBG>5.5mmol/l or systolic (SBP) ?135 or diastolic BP (DBP) ?85mmHg underwent electrocardiography (ECG). A team of cardiologists selected and accomplished exercise tolerance test (ETT) and echocardiography (Echo).Results: The prevalence of CAD was 4.5% (95% CI: 3.85 – 5.15). Compared with the female (3.5%, CI, 2.76 – 4.24) the male participants had significantly higher prevalence of CAD (6.0%, CI, 4.83 – 7.13). Comparison of characteristics between participants with and without CAD showed that age, SBP, DBP and FBG were significantly higher in CAD group. Bivariate analysis showed that age, sex, social class, glycemic status, metabolic syndrome (MetS) and smoking were significantly related to CAD. Stepwise logistic regression proved only male sex, rich social class, hypertension and diabetes had independent risk of CAD; whereas, age, obesity and dyslipidemia were proved not significant.Conclusions: The study concludes that the prevalence of CAD in a Bangladeshi rural population is comparable to other developed countries. The male sex, rich social class, hypertension and diabetes were proved to have excess risk of CAD. Neither obesity nor dyslipidemia were found significant for CAD. The younger people had similar risk as the aged ones, which necessitate primordial and primary prevention of CAD. Further study may be undertaken, which should include and consider physical activity and diet; and if possible, Creactive protein, Vitamin D and homocysteine level.IMC J Med Sci 2017; 11(2): 61-69
