Electrocardiographic left ventricular hypertrophy is not associated with increased in-hospital adverse events in patients with first Non-ST segment elevation myocardial infarction: A single center study

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.
