Diagnostic Value of Postexercise Systolic Blood Pressure Response for Detecting Coronary Artery Disease in Patients with Electrocardiographic Left Ventricular Hypertrophy / 中国医师杂志

Objective To investigate the diagnostic value of postexercise systolic blood pressure(SBP) response in detecting coronary artery disease(CAD) in patients with electrocardiographic left ventricular(LV) hypertrophy.Methods Acording to their results of selective coronary angiography,58 patients with electrocardiographic LV hypertrophy were divided into group 1(27 patients without significant coronary lesions) and group 2(31 patients with significant coronary lesions).Symptom-limited treadmill exercise testing was conducted in those patients.Results The SBP ratio(SBP at 3 minutes of recovery divided by SBP at peak exercise) was significantly higher in group 2 than in group 1(0 98?0 11 vs 0 84?0 11,P
