A Study of Prevalence of Risk Factors for Coronary Artery Diseases in Asymptomatic Middle Aged and Elderly Subjects

ABSTRACT

This study was conducted to determine the prevalence of risk factors for coronary artery disease (CAD) in apparently healthy middle aged and elderly population and to find the different between urban and rural group.Atotal of 160 individuals (80 urban and 80 rural) were included in the study. All the subjects underwent detailed history and physical examination with special emphasis on cardiovascular system. The biochemical investigations were done in all the subjects which included blood sugar, serum LDL and serum triglyceride levels. The prevalence of 2 or more than 2 risk factors were observed in 95% subjects. The prevalence of smoking was 63%, which was more prevalent in the rural population. The sedentary lifestyle was seen in 80% subjects more in females and urban group. The prevalence of asymptomatic hypertensives and isolated systolic hypertension were seen in 34% and 10% individuals respectively. Other risk factors were-diabetes mellitus (4%), Increase LDL (38%), hypertriglyceridemia (23%) and central obesity (27.50%). The two most common risk factors for CADwere sedentary lifestyle and smoking. These risk factors are modifiable and their reduction during adulthood can lead to marked reduction in the burden of CAD in middle aged and elderly Indian population.
