“…In addition, although there was no between-group differences in the presence of hyperlipidaemia, levels of both LDL and HDL were significantly higher in the GC group. Elevated HDL and hypercholesterolemia were previously shown to be associated with good collateral development [39,40]. Our findings are consistent with these data.…”

Background and objective: We aimed to investigate biochemical factors affecting coronary collateral circulation development in an elderly population aged 75 years and over. Material and methods: The study group consisted of patients with a prior coronary angiography for stable coronary artery disease (CAD). Patients with total occlusion of at least one vessel were included in the study. Enrolled patients were divided into two groups, good collateral (GC; n = 73) and bad collateral (BC; n = 55), in accordance with the Cohen-Rentop's classification system. Results: In comparison to the GC group, bilirubin levels were significantly lower (p < 0.001), and fasting plasma glucose (FPG) levels were significantly higher in the BC group (p = 0.026). Low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) levels were significantly lower in the BC group when compared to the GC group (p = 0.002 and p < 0.001, respectively). Backward elimination stepwise logistic regression analysis identified bilirubin and FPG as variables that strongly predicted the presence of a well-developed coronary collateral circulation and a poorly developed coronary collateral circulation, respectively. Conclusion: Bilirubin and FPG were seemed as the most important factors affecting coronary collateral circulation development in patients with stable CAD who were older than 75 years.

“…Some investigators have found that smoking was associated with well-developed coronary collateral circulation which might alleviate myocardial ischemia and necrosis when epicardial coronary arteries were occluded. [ 3 , 4 ] Well-developed coronary collateral circulation usually results in fewer infarct size, improved cardiac function, and fewer mortality. [ 5 – 7 ] Smoking improves coronary collateral circulation which may partial explain the so-called smokers’ paradox.…”

“…Except from smoking, other cardiovascular risk factors such as hypertension, diabetes mellites also have some impacts on coronary collateral circulation. [ 3 ] Yetkin et al [ 9 ] found that diabetes mellitus was an independent factor for rarefaction of coronary collateral circulation. However, the study by Niccoli et al [ 10 ] found that patients with diabetes mellitus had better collateral development compared with nondiabetic patients.…”

Background:Well-developed coronary collateral circulation usually results in fewer infarct size, improved cardiac function, and fewer mortality. Traditional coronary risk factors (diabetes, hypertension, and smoking) have some effects on coronary collateral circulation. However, the association between these risk factors and coronary collateral circulation are controversial. Given the confusing evidences regarding traditional cardiovascular risk factors on coronary collateral circulation, we performed this meta-analysis protocol to investigate the relationship between traditional risk factors of coronary artery disease and coronary collateral circulation.Methods:MEDINE, EMBASE, and Science Citation Index will be searched to identify relevant studies. The primary outcomes of this meta-analysis are well-developed coronary collateral circulation. Meta-analysis was performed to calculate the odds ratio (OR) and 95% confidence interval (CI) of traditional coronary risk factors (diabetes, smoking, hypertriton). Pooled ORs were computed as the Mantel–Haenszel-weighted average of the ORs for all included studies. Sensitivity analysis, quality assessment, publication bias analysis, and the Grading of Recommendations Assessment, Development and Evaluation approach (GRADE) will be performed to ensure the reliability of our results.Results:This study will provide a high-quality synthesis of current evidence of traditional risk factors on collateral circulation.Conclusion:This conclusion of our systematic review and meta-analysis will provide evidence to judge whether traditional risk factors affects coronary collateral circulation.Ethics and dissemination: Ethical approval is not required because our systematic review and meta-analysis will be based on published data without interventions on patients. The findings of this study will be published in a peer-reviewed journal.

“…15,16 Additionally, studies showed that hypertension, obesity, DM, dyslipidemia, and cigarette smoking are also associated with coronary collateral development. [17][18][19][20] Endogenous mediators, including apelin, NLR, mean corpuscular volume, monocyte count, high sensitive C reactive protein, adhesion molecules, and growth factors were shown to be related with coronary collateral development. [21][22][23][24] Additionally, Liu et al showed that CCC development is associated with race and sex.…”

Blood group types are associated with coronary artery disease. However, data are scarce about the impact of blood group types on coronary collateral circulation. In this study, we aimed to investigate the relationship between the blood group types and coronary collateral circulation. Two hundred and twelve patients who underwent coronary angiography in our department and had a stenosis of ≥ 90% in at least one major epicardial vessel were included in our study. Collateral degree was graded according to Rentrop-Cohen classification. After grading, patients were divided into poor coronary collateral circulation (Rentrop grade 0 and 1) and good coronary collateral circulation (Rentrop 2 and 3) groups. The ABO blood type of all participants was determined. The incidence rates of O blood group type were significantly higher in the good coronary collateral group compared to the poor collateral group (37.9% vs 17.1%, P < .001). The O type blood group was an independent predictor of good coronary collateral circulation (odds ratio = 1.83, 95% confidence interval = 1.56-6.18, P = .015). Coronary collateral circulation is associated with blood group types. The O blood group predicts good coronary collateral development among patients with coronary artery disease.
