Morning blood pressure surge varies with age and gender in hypertensive individuals

Many studies revealed that most cardio-cerebrovascular events were closely related to morning blood pressure surge (MBPS). The aim of our study was to investigate the relationship of MBPS with age and gender in hypertensive individuals, morning blood pressures of a total of 1100 cases with primary hypertension were analyzed. In our study, the morning systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and pulse pressure (PP) of hypertensives with MBPS were all higher (P<0.01). MBPS values were correlated with age (r = 0.061, P<0.05). In hypertensive individuals with MBPS, morning SBP and PP increased while morning DBP decreased (P<0.01) as patients aged. Morning DBP and MAP of female patients were lower while morning PP was higher (P<0.01). These results indicated that MBPS was associated with both age and gender in hypertensive individuals.
