Abstract Background Coronary artery disease (CAD) is a universal public health challenge, more prominently so in the low- and middle-income countries. In this study, we aimed to determine prevalence and trends of CAD risk factors in patients with documented CAD and to determine their effects on the age of CAD diagnosis. Materials and methods We conducted a registry-based, serial cross-sectional study using the coronary angiography data bank of the Tehran Heart Center. Adult patients who had obstructive (> 50% stenosis) CAD were included in the study. The prevalence and 11-year trends of conventional CAD risk factors were analyzed by sex and age, and their adjusted effects on the age of CAD diagnosis were calculated. Results From January 2005 to December 2015, data for 90,094 patients were included in this analysis. A total of 61,684 (68.5%) were men and 28,410 (31.5%) were women. Men were younger at diagnosis than women, with a mean age of 60.1 in men and 63.2 in women (p < 0.001), and had fewer risk factors at the time of diagnosis. Mean age at diagnosis had an overall increasing trend during the study period. Increasing trend was seen in body-mass index, hypertension prevalence, diabetes mellitus. All lipid profile components (total cholesterol, low-density lipoprotein cholesterol, triglycerides, and high-density lipoprotein cholesterol) decreased over time. Of particular interest, opium consumption was associated with 2.2 year earlier age of CAD diagnosis. Conclusion The major results of this study (lower age of CAD diagnosis in men, lower age of diagnosis associated with most risk factors, and lower prevalence of serum lipids over time) were expected. A prominent finding of this study is confirming opium use was associated with a much younger age of CAD onset, even after adjusting for all other risk factors. In addition to recommendations for control of the traditional risk factors, spreading information about the potential adverse effect of opium use, which has only recently been associated with higher risk of CAD, may be necessary.

Background and Objectives: Patients with AF are at increased risk for Coronary Artery Disease (CAD) owing to their shared etiologies and risk factors. This study aimed to assess the prevalence, cardiovascular risk factors, and used medications of CAD in AF patients. Materials and Methods: This retrospective, case-control study utilized data from the Jordanian Atrial Fibrillation (Jo-Fib) registry. Investigators collected clinical features, history of co-existing comorbidities, CHA2DS2-VASc, and HAS BLED scores for all AF patients aged >18 visiting 19 hospitals and 30 outpatient cardiology clinics. A multivariable binary logistic regression was used to asses for factors associated with higher odds of having CAD. Results: Out of 2000 patients with AF, 227 (11.35%) had CAD. Compared to the rest of the sample, those with CAD had significantly higher prevalence of hypertension (82.38%; p < 0.01), hypercholesterolemia (66.52%, p < 0.01), diabetes (56.83%, p < 0.01), and smoking (18.06%, p = 0.04). Patients with AF and CAD had higher use of anticoagulants/antiplatelet agents combination (p < 0.01) compared to the rest of the sample. Females had lower CAD risk than males (OR = 0.35, 95% CI: 0.24–0.50). AF Patients with dyslipidemia (OR = 2.5, 95% CI: 1.8–3.4), smoking (OR = 1.7, 95% CI: 1.1–2.6), higher CHA2DS2-VASc score (OR = 1.5, 95% CI: 1.4–1.7), and asymptomatic AF (OR = 1.9, 95% CI: 1.3–2.6) had higher risk for CAD. Conclusions: Owing to the increased prevalence of CAD in patients with AF, better control of cardiac risk factors is recommended for this special group. Future studies should investigate such interesting relationships to stratify CAD risk in AF patients. We believe that this study adds valuable information regarding the prevalence, epidemiological characteristics, and pharmacotherapy of CAD in patients with AF.

An inverse correlation between stature and risk of coronary artery disease (CAD) has been observed in several epidemiologic studies, and recent Mendelian randomization (MR) experiments have suggested evidence that this association may be causal. However, the extent to which the effect estimated by MR can be explained by established cardiovascular risk factors is unclear, with a recent report suggesting that lung function traits could fully explain the height-CAD effect. To clarify this relationship, we utilized the largest set of genetic instruments for human stature to date, comprising >2,000 genetic variants for height and CAD. In univariable analysis, we confirmed that a one standard deviation decrease in height (~6.5 cm) was associated with a 12.0% increase in the risk of CAD, consistent with previous reports. In multivariable analysis accounting for effects from up to 12 established risk factors, we observed a >3-fold attenuation in the causal effect of height on CAD susceptibility (3.7%, p = 2.1x10-2). We observed minimal effects of lung function traits on CAD risk in our analyses, indicating that these traits are unlikely to explain the residual association between height and CAD risk. In sum, these results suggest that height does not add meaningful clinical impact on CAD risk prediction beyond established risk factors.

BACKGROUND Routine screening of healthy individuals for the presence of cardiovascular risk factors is important for identification of high-risk coronary artery disease (CAD) patients at early stage and to provide preventive care. Considering the high burden of CAD, such investigations are of significant importance in Indian context. METHODS In this cross-sectional study, adult individuals (18 – 68 years) were evaluated for pre-existing diseases, lipid profile, blood glucose profile, thyroid profile, haemoglobin (Hb) and vitamins D3 and B12 levels after obtaining informed consent. These variables were compared between patients stratified based on their gender and age (< 40, 40 – 60, > 60 years). RESULTS A total of 1,508 participants (mean age: 49 ± 11 years; 49.9 % females) were investigated. Hypertension, diabetes, dyslipidaemia, anaemia, vitamin D3 and B12 deficiencies, hyperthyroidism, and hypothyroidism were observed in 31.2 %, 26.5 %, 32.0 %, 8.6 %, 35.3 %, 25.1 %, 21.0 % and 0.6 % of patients respectively. Prevalence of hypertension, diabetes, and dyslipidaemia increased with ageing, while deficiencies of Hb, vitamin D3, and vitamin B12 as well as hyperthyroidism and hypothyroidism were comparable across all age groups. Males were more prone to hypertension, diabetes, and dyslipidaemia, while females were more prone to have Hb deficiency, hyperthyroidism, and hypothyroidism. Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), fasting blood sugar (FBS), vitamin D3, and vitamin B12 were elevated with increase in age, while Hb levels decreased. Males exhibited higher levels of TG, low-density lipoprotein cholesterol (LDL-C), TC / HDL, LDL / HDL, FBS, and Hb, while females displayed higher levels of vitamin D3 and B12. CONCLUSIONS Our findings verify the role of age and gender on majority of cardiovascular risk factors. The high prevalence of cardiovascular risk factors is alarming and demands the need for appropriate health-care measures. KEYWORDS Age, Coronary Artery Disease, Gender, Risk Factor

Cad Risk

Although microalbuminuria is considered a strong risk factor of future cardiovascular disease (CVD), it remains unclear whether changes in urine albumin excretion (UAE) in response to a reduction of coronary risk factors may provide prognostic information in patients with coronary artery disease (CAD). Thus, this study assessed the hypothesis that changes in UAE in response to optimized therapy for reduction of CAD risk may predict future CVD events in patients with CAD. This study enrolled of 213 patients with newly diagnosed CAD who had microalbuminuria (30 mg/day ≤ UAE < 300 mg/day) at entry. Patients with late-stage chronic kidney disease (GFR < 60 ml/min/1.73 m 2 ) at entry were excluded. All patients had individualized, optimized therapies including medications and recommended life style changes to reduce risk factors for CAD according to AHA guidelines. All patients had a repeated test of UAE at 6 months (2 nd test) after the 1 st UAE test. Thereafter, all patients were prospectively followed up for 3 years or until the occurrence of 1 of the following events: CVD death, nonfatal myocardial infarction, unstable angina pectoris requiring revascularization, or ischemic stroke. Progression of UAE at the 2 nd test was defined as > 50% increase from the UAE at the 1 st test. UAE at 2 nd test was progressed in 62 (29%) patients, while it was not progressed in the remaining 151 (71%) patients. UAE at entry was comparable between patients with and without progression of UAE (52 ± 6.2 vs.61 ± 4.7 mg/day, respectively, p = ns). During follow-up period, events occurred in 15 (24%) of the 62 patients with progression of UAE and in 16 (10%) of the 151 patients without progression of UAE (p < 0.01 by chi-square test). Using a multivariate Cox hazards analysis, progression of UAE was a predictor of future CVD events that was independent of UAE at 1 st test, use of medications, age, and traditional CAD risk factors (HR 2.5, 95%CI 1.2 – 4.8, p = 0.01). Progression of urine albumin excretion despite individualized and optimized therapies to reduce CAD risk factors represents an adverse outcome in CAD patients. Periodic measurement of urine albumin excretion may be useful for risk stratification in CAD.

Abstract Background.—Coronary artery disease (CAD) is a major cause of morbidity and mortality in most Western countries and its origin involves a significant genetic component. Methods.—Genetic and epidemiologic studies have been performed to identify factors that influence the CAD risk in the population. Results.—The primary loci that have been demonstrated to be associated with increased CAD risk owing to genetic mutations include the low-density lipoprotein receptor, apolipoprotein B-100, and lipoprotein(a). Additional implicated loci include lipoprotein lipase, apolipoprotein CII, cholesteryl ester transfer protein, apolipoprotein AI, and lecithin–cholesterol acyl transferase. Conclusions.—Numerous mutations in known genes exert a major effect on CAD risk in some patients. However, in most patients with CAD, the genetic component is believed to be attributable to the aggregate effect of loci that, individually, exert only a minor influence on lipoprotein levels.

Abstract We measured lipid and lipoprotein concentrations in blood samples from control subjects and patients with coronary artery disease (CAD) in Taiwan. We found significant differences (P &lt; 0.01) in the concentrations of high-density lipoprotein cholesterol (HDLC), apolipoprotein AI (ApoAI), apolipoprotein B (ApoB), and lipoprotein(a) [Lp(a)]. Concentrations of HDLC &lt; 350 mg/L, ApoAI &lt; 900 mg/L, ApoB &gt; 800 mg/L, and Lp(a) &gt; 200 mg/L occurred, respectively, 2.8, 5.2, 1.7, and 2.3 times more frequently in the patients than in the control group. If one considers HDLC at &lt; 350 mg/L, ApoAI at &lt; 900 mg/L, ApoB at &gt; 800 mg/L, and Lp(a) at &gt; 200 mg/L as separate risk factors for CAD, the ratio of individual patients to control subjects having 4, 3, 2, 1, or 0 risk factors was [symbol: see text] 9.4, 2.1, 0.2, 0.2, respectively. Individuals displaying three or more risk factors were found 15 times more frequently in the CAD group than in the control group. These risk factors may be used clinically for the prediction and prevention of CAD in the general population.

Abstract Background Primary prevention programs for coronary artery disease (CAD) may be effective in improving health-related behavioral outcomes. However, the implementation and especially the maintanance of these programs can be very challenging mainly due to staffing cost. Thus, the present study was designed to assess the feasibility and effectiveness of a longitudinally structured, enhanced education and follow-up program for CAD prevention in an area where the diverse population and economy are major problems. Methods SANKO Coronary Artery Disesae Prevention Project (SCAD-PPI) was designed as a longitudinal study and utilized medical school students to conduct the entire project under the supervision of professors. It started in 2014 and had 2 different education and training phases. In the first phase; every school year, 2nd year Medical students underwent a one-year, specially designed training program on primary prevention for CAD. In the second phase, which took place in the 2nd year of the study, a series of conferences on primary prevention for CAD were organized by the University and local municipalities for underserved populations. Participants were prospectively assigned to an intervention where pre and post conference knowledge were collected and assessed. Every intervention was conducted by specially trained 3rd year Medical students and an education booklet which was specifically designed for this study was given to the participants. Every other month thereafter, for 6 months, each participant was followed by phone. At the 6 month follow -up, data was collected to assess the impact of enhanced education and follow-up program on behavioral outcomes. Results A total of 135 participant were enrolled; 79% were women, mean age was 41±13 years, only 29% had a graduate school degree; 56% were not working. Mean BMI was 28.3±5.1kg/m2. Overall knowledge on CAD risk factors, primary prevention measures, diet and daily exercise habits were very poor. After the enhanced education and follow-up program there was a significant improvement on the knowledge of CAD risk factors and primary prevention measures (p&lt;0.001). More importantly, the follow-up program led participants to implement those positive changes into their lives and maintain a healthy life style. A separate cost analysis showed significant savings. Conclusion This is the first study which showed that a longitudinally structured training program of medical students could be utilized to implement an enhanced education and follow–up program for primary prevention of CAD in an economically challenged, underserved population with successful outcomes. This model program is not only cost-effective and beneficial for public interest but also enhances active interaction of medical students with patients at a very early stage of their career.

Background: The relationship between breast artery calcification (BAC) noted on mammography and both coronary artery disease and cardiovascular risk remains controversial. Few studies have examined the clinical significance of BAC in asymptomatic women. In the present study we evaluated the relationship between BAC and coronary artery calcium (CAC) as identified by multi-slice CT scanning (MSCT). Patients and methods: Consecutive women (n = 98) with BAC noted on routine mammography but without known coronary artery disease (CAD) were assessed for CAD risk factors and had assessment of coronary calcium by MSCT. A control cohort of consecutive women who were BAC(-) (n = 104) underwent an identical assessment. Results: Women who were BAC(+) were older than those who were BAC(-); otherwise, there were no differences between the 2 groups with regard to traditional cardiac risk factors. Significantly more BAC(+) vs. BAC(-) women were found to have “high risk” CAC scores, defined as CAC > 400 (11.2 % vs. 1.0 %, p = 0.006). However, the rates of CAC scores of 0 were not different between the two groups (50.0 % vs. 54.8 % for BAC(+) and BAC(-) , respectively, p = 0.586). When examined in a multivariate model including the traditional risk factors of diabetes, increasing age, smoking, hyperlipidemia, and family history of CAD, the presence of BAC remained significantly associated with CAC > 400 (OR = 22.6, 95 % CI = 2.1 - 237.1). Conclusions: The presence of breast artery calcium on screening mammography was a strong independent predictor (odds ratio > 22) of high risk coronary artery calcium scores (defined as CAC > 400). The presence of BAC in those with significant CAD risk factors may warrant further evaluation.
