Predictive Value of Risk Factors in Coronary Artery Disease in Hypertensive Versus Normotensive Patients

Many risk factors are important in genesis of coronary artery disease. Their effect and prevalence are different in hypertensive patients. The aim of this study was to evaluate the predictive value of cardiac risk factors in hypertensive patients and compare those in normotensive patients. With descriptive cross sectional study and random sampling, 976 of 3000 patients’ units who underwent coronary angiography (CAG) during year of 2004 were studied. Demographic and angiographic data were collected. Data entry and analysis were done by SPSS 11.5 and EPI 6 statistical software. Prevalence of patients who underwent CAG was 60.5%. Mean age of patients were 58.6 and 53.9 years and prevalence of CAD were 84 and 84.5 percent in hypertensive and non hypertensive patients respectively. Prevalence of two and three vessel disease was higher in hypertensive patients. Male gender, diabetes, hyperlipidemia and age were main predictors of CAD in hypertensive patients but in normotensive patients male gender, smoking, familial history and age were major predictors. Prevalence of HTN, RFs and CAD are high in patients who underwent CAG and pattern of CAD in our country follows western country patterns. Male gender, diabetes, hyperlipidemia and age were main predictors of CAD in hypertensive patients, respectively regarding to high prevalence of cardiac risk factors and their severe effect on genesis of CAD in hypertensive patients rapid health measures are needed for control of HTN in general population.
