Background: There is conflicting data about prognostic implication of electrocardiographic (ECG) left ventricular hypertrophy (LVH) in patients with first non- ST-segment elevation myocardial infarction (NSTEMI). We aimed to examine the association of left ventricular hypertrophy (LVH) on admission electrocardiogram with adverse outcomes in patients with NSTEMI.
Methods: In the present study, 460 patients (77.5% males with mean age of 65.44±13.15 years) with first NSTEMI were evaluated. ECG left ventricular hypertrophy (LVH) was diagnosed based on Sokolow-Lyon voltage criteria. Baseline laboratory and clinical results, angiographic data, as well as in- hospital adverse events were compared between the patients with and without LVH.
Results: Electrocardiographic LVH was observed in 74 (16.1%) patients. Patients with LVH had higher admission systolic blood pressure (132.91±21.08 vs 125.80±21.78; P=0.01) and higher peak troponin (6.42±1.03 vs 4.41±0.28; P=0.004), but less likely to undergo coronary angiography (54.1% vs 66.8%; P=0.03) .Patients with electrocardiographic LVH had similar in-hospital mortality (5.4% vs 3.6%, P=0.5) and heart failure/ pulmonary edema (2.7% vs 2.07%, P=0.6) compared to patients without LVH.
Conclusion: The present study showed that among the patients with first NSTEMI, electrocardiographic LVH was not associated with increased in-hospital adverse events.
