Coronary artery ectasia in Egyptian patients with coronary artery disease.

RESUMO

We conducted a retrospective study of 45 Egyptian patients with coronary artery ectasia who underwent coronary bypass grafting at our institution between 1980 and 1995. We examined the anatomic distribution and type of coronary ectasia and its association with coronary risk factors in these patients, and evaluated the severity of their coronary artery disease. We compared these findings with those from a group of 230 Egyptian patients who did not have coronary ectasia. These patients also underwent coronary artery bypass grafting between 1980 and 1995 at our institution. Obesity was present in 60% of the patients who had coronary artery ectasia, compared with 42% of patients who did not have ectasia (P < 0.01). Coronary artery ectasia was not related to any coronary risk factors other than obesity. However, patients who had ectasia did have a higher rate of triple-vessel coronary artery disease than did patients without ectasia (82% vs 67%, P < 0.05). Of the coronary vessels affected by ectasia, 43% were left anterior descending arteries. Diffuse disease was noted in 84% of all ectatic segments. We conclude that in this patient population, 2 conditions had a positive correlation with coronary ectasia: obesity and the severity of coronary artery disease.
