Background and Objective: Coronary artery disease (CAD) is the major cause of deaths and injuries in the world, including Iran and higher percentage of deaths occur in young people. The purpose of this study was to evaluate the prevalence of coronary artery disease in the past decade among young people referring to the hospital.
Subjects and Methods: This cross-sectional epidemiological study was based on data collected from patients records admitted for elective angiography Ahvaz Golestan Hospital from 2001 to 2011. The patients were divided into 5 age groups. Each group wasallocated according to number and severity of CAD, into five groups; normal (without conflicts), minimal (conflicts below 50 %), one, two and three vessels stenosis. Severity of coronary artery disease in each age group were compared with ten years later.
Results: The overall CAD prevalence was 67.6% in 2001 and 65.3% in 2011 (P<0.54). In 2001, the prevalence of coronary artery disease in five groups (equal and younger than 45, 46-50, 51-55, 56-60, and elder than 60year-old) were 52.45, 68.1, 66.6, 71.1, 83.3 percent, respectively; and in 2011, 42.2, 56.25%, 60%, 69.5% and 79.4 percent, respectively. (P-values were respectively: 0.29, 0.19, 0.48, 0.85 and 0.57).
Conclusion: The overall prevalence of coronary artery disease among different age groups did not change significantly over time. It seems that there is no significant change in frequency of CAD between 2001 and 2011 years in this study
