Objectives. We aim to evaluate long-term outcomes after left main coronary artery (LMCA) percutaneous coronary intervention (PCI) in patients presenting with acute coronary syndrome (ACS). Background. PCI of the LMCA has been an acceptable revascularization strategy in stable coronary artery disease. However, limited studies on long-term clinical outcomes of LMCA PCI in ACS patients are available. Methods. A total of 6429 consecutive patients with ACS undergoing PCI in Fuwai Hospital in 2013 were enrolled. Patients are divided into LMCA group and Non-LMCA group according to whether the target lesion was located in LMCA. Prognosis impact on 2-year major adverse cardiovascular and cerebrovascular events (MACCE) is analyzed. Results. 155 (2.4%) patients had target lesion in LMCA, while 6274 (97.6%) patients belong to the non-LMCA group. Compared with non-LMCA patients, LMCA patients have generally more comorbidities and worse baseline conditions. Two-year follow-up reveals that LMCA patients have significantly higher rate of cardiac death (2.6% vs. 0.7%, p=0.034), myocardial infarction (7.1% vs. 1.8%, p<0.001), in-stent thrombosis (4.5% vs. 0.8%, p<0.001), and stroke (7.1% vs. 6.4%, p=0.025). After adjusting for confounding factors, LMCA remains independently associated with higher 2-year myocardial infarction rate (HR = 2.585, 95% CI = 1.243–5.347, p=0.011). Conclusion. LMCA-targeted PCI is an independent risk factor for 2-year myocardial infarction in ACS patients.

The Mean

We aim to describe the in-hospital outcomes of the first reported Canadian cohort of patients with cardiogenic shock and acute myocardial infarction (MI) due to acute and total occlusion of the left main coronary artery, treated with initial percutaneous coronary intervention (PCI). Acute left main thromboses with cardiogenic shock were identified (N = 8) from a retrospective consecutive cohort of high risk left main PCI (N = 56) performed at our institution from 2004–2009. The mean age was 62.3 ± 13.2 years, with 6 (75%) male patients. Successful PCI was performed in all patients, with thrombectomy utilized in 4 patients (50%), stenting in 7 patients (88%), and intra-aortic balloon pump augmentation in 7 patients (88%). Two patients (25%) required extracorporeal membrane oxygenation (ECMO) and 2 other patients required ventricular assist devices. Post-PCI coronary artery bypass grafting (CABG) was performed for 2 patients (25%). The mean SYNTAX score was 26.6 ± 10.5. The mean logistic EuroSCORE was 30.4 ± 12.6%. In-hospital mortality occurred in 3 patients (38%). Acute left main occlusion is a rare but devastating presentation of myocardial infarction, invariably with cardiogenic shock. Emergent PCI may be an effective method to acutely revascularize this subset of patients; however, aggressive post-PCI care including ECMO, CABG, and ventricular support may be required to improve patient survival.
