A description of gender differences in angiographic findings in a single-center Iranian hospital

Coronary angiography is one of the most common hospital procedures, though there is limited information on the location and extent of coronary artery blockages other than for predominately White patients. This study examined the location and magnitude of coronary artery blockages in patients admitted to a leading tertiary heart hospital in Iran with symptoms of coronary artery disease (CAD). This retrospective descriptive study aimed to review angiography records of all patients with symptoms of CAD undergone diagnostic coronary angiography between February 2002 and September 2004. A total of 94 consecutive angiographic records were analyzed to determine the culprit coronary arteries and the severity of CAD. The findings of the study showed that double- vessel disease was the commonest type of CAD. The left anterior descending (LAD) artery was the most common culprit artery (84%), followed by RCA (64%), CX (37%), OM (13%) and LMS (3%). Our study showed a relatively high angiographic prevalence of LAD blockages. The results of this study provide additional support for the significance of ethnicity in the extent of coronary artery blockages.
