LONG-TERM FOLLOW-UP AFTER ACUTE MYOCARDIA L-INFARCTION DUE TO NONATHEROSCLEROTIC SPONTANEOUS CORONARY-ARTERY DISSECTION

Spontaneous coronary artery dissection is a rare cause of acute myocar dial infarction, primarily in young women. The etiology of dissections is still under discussion. Possible factors are inflammation, changes of flow dynamics, and preexisting intima lesions. We report on two yo ung women, 49 and 30 years of age, who suffered and acute anterior wal l infarction. Coronary angiography confirmed diagnosis of spontaneous coronary artery dissection of the LAD in the acute an subacute phase o f acute myocardial infarction. The patients suffered no further cardia c events at longterm follow-up of up to 9 years.
