ABSTRACT
BACKGROUND: Coronary Artery Disease (CAD) is one of the most common causes of death in Palestine. This study aimed to assess the nontraditional risk factors among CAD patients underwent invasive coronary angiography in Gaza-Palestine. METHODS: Unmatched one-to-one case-control study was conducted among 200 participants. Cases were recruited from newly discovered CAD patients after a confirmed diagnosis of CAD by interventional cardiologist post catheterization "coronary angiography" in Al-Shifa Cardiovascular Catheterization Center. Controls were enrolled from individuals with no history of CAD. An interview-based questionnaire was used to assess patient's characteristic data and medical history; anthropometric, and the Ankle Brachial Index(ABI) was measured and calculated. Furthermore, biochemical analysis of high sensitivity C-reactive protein (hs-CRP) level and Random blood glucose level (RBG) and Leukocyte count (WBCs)were investigated. All required ethical approvals were obtained. Data were managed and analyzed by STATA version 14. Correlation analysis by multivariate logistic regression was done. RESULTS: hs-CRP, RBG, and WBCs remained significant predictors for CAD adjusted for age, education level, employment status, and monthly income. As, the odds of CAD increased by 3% for each unit increased in hs-CRP (Odd Ratio (OR)=1.03; 95% confidence interval (CI):1.01, 1.06; P = 0.020); and the odds of CAD was augmented by 30% for each unit increased in WBCs (OR= 1.30; 95% CI: 1.07, 1.67; P = 0.010); While the odds of CAD was 5 times more for each unit increased in RBG (OR=5.04; 95% CI: 1.17, 14.88; P = 0.003). Still, age remained a significant risk factor as the odds of CAD was 19% more for each increased year in age (OR=1.19; 95%CI: 1.13, 1.26; P<0.001). CONCLUSION: Nontraditional factors (hs-CRP, RBG, and WBCs) are significant predictors of CAD, and should be considered in adult patients coming with attacks of angina pain.
