Positive Exercise Stress Test in Bus Drivers

Background:Drivers have a higher risk of cardiovascular disease and the frequencies of risk factors and IHD is prevalent among them. Methods: 176 bus drivers were participated in the study. Frequency of risk factors and Positive exercise stress test were evaluated. Findings: The average age of studied subjects was 47.47 years. The waist circumference in 23.19% of them was more than 102cm. The prevalence of obesity and overweight in drivers were 75.5% and 30.7% of them had hypertension and 60.2% were smoker. Exercise stress test was positive in 9.7% of drivers. Conclusion: Frequency of cardiovascular risk factors in drivers was considerably high. However, frequency of positive exercise stress test was not higher than other population in similar study. The reason of normal incidence of positive exercise stress test in drivers, despite the poorer risk profile, may be due to overall lower ischemic heart disease in Iranian population. key words: Exercise stress test, Risk factor, Driver.
