Correlations between left ventricular mass and systolic blood pressure at rest and during maximal exercise in moderately hypertensive men.
We examined 87 men with moderate hypertension (diastolic blood pressure, DPB, greater than or equal to 95 and less than 110 mmHg) (mean age 45, range 22-64, years) with echocardiography and maximal ergometer bicycle test. Left ventricular mass index (LVMI) was calculated according to the Penn convention. Mean LVMI was 126 (60-210) g/m2. The maximal systolic blood pressure (SBP) during exercise was on average 217 (155-260) mmHg. Linear regression analysis revealed a significant correlation between LVMI and SBP at rest (r = 0.48, P less than 0.001) and during exercise (r = 0.39, P less than 0.001). Multiple regression analysis correcting for differences in age, cumulative work and cholesterol level revealed a significant correlation between LVMI and SBP at rest (t = 4.07, P less than 0.0001) and during exercise (t = 3.25, P = 0.002). Thus in patients with established, moderate hypertension exercise SBP is not more predictable for LVMI than is SBP at rest.
