Association of Target Organ Damage With 24-Hour Systolic and Diastolic Blood Pressure Levels and Hypertension Subtypes in Untreated Chinese

The association of target organ damage with 24-hour systolic and diastolic blood pressure levels and ambulatory hypertension subtypes has not yet been examined in untreated Chinese patients. We measured left ventricular mass index by echocardiography (n=619), the urinary albumin: creatinine ratio (n=1047), and aortic pulse wave velocity by tonometry (n=1013) in 1047 untreated subjects (mean age, 50.6 years; 48.9% women). Normotension was a 24-hour systolic/diastolic blood pressure = 0.39), but higher urinary albumin: creatinine ratio (+1.24 mg/mmol; P=0.002). In younger participants (
