Add-on effect of bedtime dosing of the alpha(1)-adrenergic receptor antagonist doxazosin on morning hypertension and left ventricular hypertrophy in patients undergoing long-term amlodipine monotherapy.

High morning blood pressure is related to target organ damage and future cardiovascular events. Chronobiologic therapies focusing on the early morning period may be an important strategy for antihypertensive therapy. The aim of this study was to clarify the add-on effects of bedtime dosing of the alpha(1)-adrenergic receptor antagonist doxazosin on morning blood pressure in patients with essential hypertension who were under long-acting calcium channel blocker amlodipine monotherapy.

Morning rise of blood pressure assessed by home blood pressure monitoring is associated with left ventricular hypertrophy in hypertensive patients receiving long-term antihypertensive medication.

To assess the influence of morning rise of systolic blood pressure (SBP) as assessed by home blood pressure monitoring on the left ventricular mass index (LVMI) in relation to the blood pressure control status, we evaluated M-mode cardiac echocardiography in 626 hypertensive subjects (412 men and 214 women; mean age, 61.3+/-10.1 years) who were receiving antihypertensive medication.

Morning rise in blood pressure is a predictor of left ventricular hypertrophy in treated hypertensive patients.

To assess the relationship between home blood pressure and left ventricular mass, we evaluated cardiac echocardiography in 297 hypertensive subjects (188 men and 109 women; mean age, 62.8+/-10.3 years) who were treated with amlodipine monotherapy over 1 year (mean dose, 5.
