Early and Mid‐Term Clinical Outcome of Emergency PCI in Patients with STEMI due to Unprotected Left Main Coronary Artery Disease

Early and Mid‐Term Clinical Outcome of Emergency PCI in Patients with STEMI due to Unprotected... Objectives: Evaluation of acute and mid‐term outcomes of patients with ST‐elevation myocardial infarction (STEMI) undergoing emergency PCI due to unprotected left main coronary artery (ULMCA) disease. Background: STEMI patients due to ULMCA disease represent a rare, high risk group. Percutaneous coronary intervention (PCI) may be the preferred strategy of myocardial revascularization but there are few data about this topic. Methods: We analyzed 30‐day and mid‐term mortality of 58 patients with STEMI and ULMCA disease as culprit lesion treated in our centre by emergency PCI between 2000 to 2010. Results: Mean age was 67.3 ± 11.5 years. Thirty (51.7%) patients had cardiogenic shock on admission. PCI success was achieved in 54 patients (93.1%). Mean follow‐up was 15.8 ± 10.9 months (median 14, range 6–45). Thirty‐day and mid‐term mortality rates were 39.7% and 44%. Backward binary logistic regression model identified cardiogenic shock at presentation (OR 12.6, 95% CI 2.97–53.6, P < 0.001), age ≥75 years (OR 5.9, 95% CI 1.3–26.5, P = 0.019) and post‐PCI TIMI flow grade <3 (OR 2.9, 95% CI 1.8–5.7 P = 0.02) as independent predictors of 30‐day mortality. Cox proportional hazard ratio (HR) identified shock at presentation (HR 5.2, 95% CI 1.8–14.3, P < 0.002), age ≥75 years (HR 3.9, 95% CI 1.8–8.7, P < 0.001), post‐PCI TIMI flow grade <3 (HR 4.9, 95% CI 1.6–14.6; P < 0.005) as independent predictors of mid‐term mortality. Conclusions: In patients with STEMI and ULMCA as culprit lesion, emergency PCI is a valuable therapeutic strategy. Early and mid‐term survival depends on cardiogenic shock, advanced age, and PCI failure. Patients surviving the first month have good mid‐term prognosis.

Abstract

Objectives: Evaluation of acute and mid‐term outcomes of patients with ST‐elevation myocardial infarction (STEMI) undergoing emergency PCI due to unprotected left main coronary artery (ULMCA) disease. Background: STEMI patients due to ULMCA disease represent a rare, high risk group. Percutaneous coronary intervention (PCI) may be the preferred strategy of myocardial revascularization but there are few data about this topic. Methods: We analyzed 30‐day and mid‐term mortality of 58 patients with STEMI and ULMCA disease as culprit lesion treated in our centre by emergency PCI between 2000 to 2010. Results: Mean age was 67.3 ± 11.5 years. Thirty (51.7%) patients had cardiogenic shock on admission. PCI success was achieved in 54 patients (93.1%).
