Comparison of frequency of left ventricular wall motion abnormalities in patients with a first acute myocardial infarction with versus without left ventricular hypertrophy.
One hundred fifty patients with their first acute myocardial infarctions (AMIs) were studied. AMIs were confirmed by troponin levels, ST-segment elevation, or angiographic coronary occlusion. In 36% of patients (16 of 45) with left ventricular (LV) hypertrophy, the wall motion score index was normal, whereas in patients with no LV hypertrophy, only 18% (19 of 105) had no segmental wall motion abnormalities (p = 0.03). When adjusting for troponin level, the odds ratio for normal wall motion of patients with LV hypertrophy was 2.86 (95% confidence interval 1.26 to 6.50) compared with those with normal wall thickness. Consequently, normal LV wall motion by echocardiography in the setting of LV hypertrophy does not exclude AMI.
