The prognosis in men and women with myocardial infarction due to left main coronary artery disease (LM) in relation to the presence of isolated LM disease or accompanying one-, two- or multivessel disease. A total of 643 consecutive patients (184 females, 459 males) with acute myocardial infarction due to LM stenosis or occlusion were enrolled. Data on clinical presentation, management and in-hospital mortality derived from the Polish Registry of Acute Coronary Syndromes PL-ACS, data on 12-month mortality derived from the Civil Registry. Patients with isolated LM disease were compared with patients in whom significant stenosis in artery another than LM was present. In-hospital, 30-day, 6- and 12-month mortality in both genders were analyzed. The disease severity was similar in men and women. No difference in mortality between all subgroups was observed. A non-significant trend towards higher mortality in patients with multivessel disease accompanying to LM disease when compared to patients with isolated LM disease (34.2% vs. 25.2%; p log rank = 0.06). There was no difference in in-hospital and long-term mortality between patients with isolated LM disease vs. patients with accompanying multivessel disease. No difference in mortality between genders was noticed. A longer follow-up is needed to confirm the significance of higher mortality in patients with multivessel disease.
