Key result
In patients with acute STEMI undergoing emergent revascularization for LMCA obstruction, renal insufficiency was independently predictive of in-hospital mortality (OR 5.642).
Cohort (n=38)
No
Odds Ratio: 5.642 (95% CI 1.197–26.575)
p-value: p=0.029
In patients with STEMI due to LMCA obstruction undergoing emergent revascularization, mortality remains extremely high (42.1% at 30 days), with renal insufficiency and a Parsonnet score > 20 serving as strong predictors of adverse outcomes.

Renal insufficiency identifies high-risk LMCA STEMI patients; hypothesis-generating for targeted interventions pending prospective validation.
Cheng et al. (2008) conducted a cohort in Acute ST-segment elevation myocardial infarction with left main coronary artery obstruction (n=38). Renal insufficiency vs. Normal renal function was evaluated on In-hospital mortality (OR 5.642, 95% CI 1.197-26.575, p=0.029). In patients with acute STEMI undergoing emergent revascularization for LMCA obstruction, renal insufficiency was independently predictive of in-hospital mortality (OR 5.642).
