Background and Purpose: Coronary artery disease in moyamoya disease (MMD) have been described sporadically in several case reports. The purpose of this study is to determine the prevalence and characteristics of coronary artery disease in patients with MMD. Methods: From August 1991 to December 2012, 446 patients diagnosed with adult MMD at our hospital. Baseline characteristics and prevalence of coronary artery disease were reviewed based on medical records and laboratory findings. The findings of conventional coronary angiography and/or coronary computed tomography were also reviewed for the presence and appearance of coronary artery lesion. Results: - Of 446 patients with adult MMD, 21 patients were found to have coronary artery disease. Ten patients were treated with coronary artery bypass graft (n=4) or percutaneous coronary intervention (n=6) for unstable angina or myocardial infarction. Eleven were treated with medication for stable angina (n=6) and variant angina with mild degree of stenosis (n=5). Median age at diagnosed with coronary artery disease of these patients were 44 (range, 27-59). Two patients showed calcification on coronary artery lesion. Comorbid stroke risk factor rate were 19%, 38%, 9.5% and 19 % in diabetes, hypertension, dyslipidemia and smoking. Six of 21 patients had more than 2 risk factor. Conclusion: - Twenty one (4.7%) of our adult MMD registry patients showed coronary artery disease. And only 2 (9.5%) showed calcification which might means that atherosclerosis burden is low in coronary artery disease with MMD. Coronary artery disease might be a clinically relevant systemic manifestation in patients with MMD, considering early onset coronary diseaes and low prevalence of stroke risk factor.

Abstract Background Anemia is a frequent comorbidity in patients with coronary artery disease (CAD). Besides a complemental effect on myocardial oxygen undersupply of CAD and anemia, available data suggests that it may independently impact the prognosis in CAD patients. We aimed to determine the association of anemia with long-term survival in a longitudinal registry of patients undergoing conventional coronary angiography. Methods The present analysis is based on the ECAD registry of patients undergoing conventional coronary angiography at the Department of Cardiology and Vascular Medicine at the University Clinic Essen between 2004 and 2019. For this analysis, we excluded all patients with missing hemoglobin levels at baseline admission or missing follow-up information. Anemia was defined as a hemoglobin level of <13.0g/dl for male and <12.0g/dl for female patients according to the world health organization's definition. Cox regression analysis was used to determine the association of anemia with morality, stratifying by clinical presentation of patients. Hazard ratio and 95% confidence interval are depicted for presence vs. absence of anemia. Results Overall, data from 28,917 patient admissions (mean age: 65.3±13.2 years, 69% male) were included in our analysis (22,570 patients without and 6,347 patients with anemia). Prevalence of anemia increased by age group (age <50 years: 16.0%, age ≥80 years: 27.7%). During a mean follow-up of 3.2±3.4 years, 4,792 deaths of any cause occurred (16.6%). In patients with anemia, mortality was relevantly higher as compared to patients without anemia (13.4% vs. 28.0% for patients without and with anemia, respectively, p<0.0001, figure 1). In univariate regression analysis, anemia was associated with 2.4-fold increased mortality risk (2.27–2.55, p<0.0001). Effect sizes remained stable upon adjustment for traditional risk factors (2.38 [2.18–2.61], p<0.0001). Mortality risk accountable to anemia was significantly higher for patients receiving coronary interventions (2.62 [2.35–2.92], p<0.0001) as compared to purely diagnostic coronary angiography examinations (2.31 [2.15–2.47], p<0.0001). Likewise, survival probability was slightly worse for patients with anemia in acute coronary syndrome (2.70 [2.29–3.12], p<0.0001) compared to chronic coronary syndrome (2.60 [2.17–3.12], p<0.0001). Interestingly, within the ACS entity, association of anemia with mortality was relevantly lower in STEMI patients (1.64 [1.10–2.44], p=0.014) as compared to NSTEMI and IAP (NSTEMI: 2.68 [2.09–3.44], p<0.0001; IAP: 2.67 [2.06–3.47], p<0.0001). Conclusion In this large registry of patients undergoing conventional coronary angiography, anemia was a frequent comorbidity. Anemia relevantly influences log-term survival, especially in patients receiving percutaneous coronary interventions. Our results confirm the important role of anemia for prognosis in patients with coronary artery disease, demonstrating the need for specific treatment options. Figure 1.

Abstract There are well-known traditional risk factors for coronary artery disease (CAD). Among them, smoking is one of the most prominent and modifiable risk factors. This study aims to determine the magnitude of smoking as a risk factor for CAD in the Nepalese population. A hospital-based age- and sex-matched case–control study was carried out with a total of 612 respondents. Bivariate analysis showed that the risk of developing CAD in ex-smokers and current smokers was higher (odds ratio (OR): 1.81 (confidence interval (CI): 1.21–2.7) and OR: 5.2 (CI: 3.4–7.97)), with p-values less than 0.004 and <0.00001, respectively, compared to the risk in never smokers. From stratified socio-demographic, cardio-metabolic, behavioural and psychosocial risk factor analysis, smoking was found to be associated with CAD in almost all subgroups. In the subsequent multivariate analysis, adjustment for socio-demographic, cardio-metabolic and psychosocial risk factors showed a steady increase in risk. However, further adjustment for behavioural risk factors (alcohol use and physical activity) showed that the risk was attenuated by 59% in current smokers. After adjusting for the covariates, current smokers and ex-smokers had an increased risk of CAD (OR: 6.64, 95% CI: 3.64–12.12, p < 0.00001; OR: 1.89, 95% CI: 1.08–3.31, p < 0.012, respectively) compared with non-smokers. In conclusion, smoking was found to increase the risk of CAD in the Nepalese population.

SummaryRecently, we have demonstrated that human platelet antigen 1b (HPA-1b or PlA2) is a hereditary risk factor for platelet thrombogenicity leading to premature myocardial infarction in preexisting coronary artery disease. However, HPA-1b does not represent a risk factor for coronary artery disease itself. The aim of our present study was to evaluate the role of HPA-1b on the outcome in patients after coronaryartery bypass surgery. We prospectively determined the HPA-1 genotype in 261 consecutive patients prior to saphenous-vein coronaryartery bypass grafting. The patients were followed for one year. Among patients with bypass occlusion, myocardial infarction, or death more than 30 days after surgery, the prevalence of HPA-1b was significantly higher than among patients without postoperative complications (60 percent, 6/10, vs. 24 percent, 58/241, p <0.05, odds ratio 4.7). Using a stepwise logistic regression analysis with the variables HPA1b, age, sex, body mass index, smoking (pack-years), hypertension, diabetes, cholesterol and triglyceride concentration, only HPA-1b had a significant association with bypass occlusion, myocardial infarction, or death after bypass surgery (p = 0.019, odds ratio 4.7). This study shows that HPA-1b is a hereditary risk factor for bypass occlusion, myocardial infarction, or death in patients after coronary-artery bypass surgery.
