title: Assessment of ventricular function in arterial hypertension with radionuclide ventriculography.
abstract: Diastolic function of the left ventricle was assessed in 29 untreated patients with mild to moderate hypertension and in 21 normotensive control subjects using gated radionuclide ventriculography. In hypertensive patients, the time to peak filling rate was significantly longer (p less than 0.01) than that in control subjects, and first-third filling fraction and peak filling rate were significantly reduced (p less than 0.001). The ejection fraction and peak ejection rate were also significantly reduced in hypertensive patients (p less than 0.001). No relation was observed between diastolic functional impairment and age, cardiac hypertrophy, or severity of hypertension. Thus, early impairment of ventricular filling is present in hypertension, even in young patients without evidence of cardiac hypertrophy.
