title: Relation of electrocardiographic left ventricular hypertrophy with and without T-wave changes to systemic blood pressure, body mass, and serum lipids and blood glucose levels in Japanese men.
abstract: Left ventricular (LV) hypertrophy, especially combined with an abnormal ST-T, is considered 1 of many coronary risk factors. Seven hundred forty-nine Japanese men were selected according to their electrocardiographic findings, i.e., normal electrocardiogram, LV hypertrophy without an abnormal ST-T segment, LV hypertrophy with a flat T wave, and LV hypertrophy with a negative T wave. Coronary risk factors were compared among these 4 age-matched groups. Groups with LV hypertrophy with negative or flat T waves had larger body mass index (24.9 vs 22.9 kg/m2), higher mean systemic blood pressure (111 vs 95 mm Hg), larger LV mass (265 vs 157 g), higher blood glucose (110 vs 100 mg/dl), higher serum triglyceride (148 vs 122 mg/dl), higher total cholesterol (206 vs 198 mg/dl), and lower high-density lipoprotein cholesterol (47 vs 54 mg/dl) than the normal group or the group with LV hypertrophy without T-wave change. Among these risk factors, blood pressure and glucose remained higher even after the adjustment by body mass index or by body mass index and blood pressure. Electrocardiographic LV hypertrophy with a changed T wave signified higher risk of coronary artery disease in Japanese men.
