Multivariate analysis of risk factors in coronary artery disease in Jordan

The blood of 440 patients with documented acute myocardial infarction, 355 men (mean ± SEM age, 54.97 ± 0.59 years) and 85 women (mean age, 60.96 ± 1.22 years), was tested for serum cholesterol, triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), fasting blood sugar, uric acid, and serum creatinine. Systolic and diastolic blood pressure and cigarette smoking were included in the analysis. Students t test distribution, standard method of correlation, and multiple regression analysis were used. There was a significant statistical correlation between HDL and both systolic and diastolic blood pressure as well as serum cholesterol level. A significant statistical correlation was found between serum LDL-cholesterol level and diastolic blood pressure, uric acid, and triglycerides. Women tended to have a significantly higher mean age (P < 0.001), systolic blood pressure (P < 0.03), and fasting blood sugar (P < 0.001). Cigarette smoking was significantly higher in males (P < 0.001).
