Doppler echocardiographic assessment of filling and emptying parameters and ambulatory blood pressure measurements in normotensives and hypertensives.
To evaluate the relationship between office and ambulatory BP measurements and filling and emptying parameters, 15 hypertensive and 15 control subjects underwent both 24 hour ambulatory BP monitoring and Doppler echocardiography. No patient received antihypertensive medication for 3-4 weeks, had echocardiographic left ventricular hypertrophy (greater than or equal to 12 mm) or a diastolic BP greater than 100 mm Hg. The time from R wave on the electrocardiogram to onset of ejection was prolonged in hypertensives (P less than 0.05). There were no differences between the hypertensives and normotensives for diastolic filling abnormalities. Finally, neither office nor ambulatory BP correlated with either Doppler filling or emptying parameters.
