We aimed to examine the association of left ventricular hypertrophy (LVH) on admission electrocardiogram with adverse outcomes in patients with NSTEMI.<br> <span style="color:#0000FF;"><strong><em>Methods</em></strong><em>:</em> </span>In the present study, 460 patients (77.5% males with mean age of 65.44&plusmn;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.<br> <span style="color:#0000FF;"><strong><em>Results</em></strong><em>:</em></span> Electrocardiographic LVH was observed in 74 (16.1%) patients. Patients with LVH had higher admission systolic blood pressure (132.91&plusmn;21.08 vs 125.80&plusmn;21.78; P=0.01) and higher peak troponin (6.42&plusmn;1.03 vs 4.41&plusmn;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.<br> <span style="color:#0000FF;"><strong><em>Conclusion</em></strong><em>:</em> </span>The present study showed that among the patients with first NSTEMI, electrocardiographic LVH was not associated with increased in-hospital adverse events.</span></span><br> <p style="margin: 0px 0px 10.66px;"></p> Non ST-segment elevation myocardial infarction (NSTEMI), Left ventricular hypertrophy (LVH), Electrocardiography (ECG), in-hospital mortality 289 294 http://caspjim.com/browse.php?a_code=A-10-1244-1&slc_lang=en&sid=1 Fatemeh Bakhtiari fatemehbakhtiarii@yahoo.com 100319475328460018063 100319475328460018063 No Cardiovascular Research Center, Cardiology Department, Tabriz University of Medical Science, Tabriz, Iran Ghiti Davarmoin ghitidavarmoin@gmail.com 100319475328460018064 100319475328460018064 No Cardiovascular Research Center, Cardiology Department, Tabriz University of Medical Science, Tabriz, Iran Samad Ghaffari ghafaris@gmail.com 100319475328460018065 100319475328460018065 No Cardiovascular Research Center, Cardiology Department, Tabriz University of Medical Science, Tabriz, Iran Naser Aslanabadi aslanabadin@gmail.com 100319475328460018066 100319475328460018066 No Cardiovascular Research Center, Cardiology Department, Tabriz University of Medical Science, Tabriz, Iran Ahmad Separham aseparham@gmail.com 100319475328460018067 100319475328460018067 Yes Cardiovascular Research Center, Cardiology Department, Tabriz University of Medical Science, Tabriz, Iran
