Comparison of frequency of left ventricular wall motion abnormalities in patients with a first acute myocardial infarction with versus without left ventricular hypertrophy

Abstract

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.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
