Radionuclide ventriculography in the evaluation of left-ventricular function in patients with arterial hypertension

Systemic and intracardiac hemodynamic parameters were examined in 29 patients with arterial hypertension by radionuclide ventriculography. No impairments were found in resting left ventricular pump function in the patients. Left ventricular diastolic function exhibited 24 and 34.5% reductions in lef...

Summary:Systemic and intracardiac hemodynamic parameters were examined in 29 patients with arterial hypertension by radionuclide ventriculography. No impairments were found in resting left ventricular pump function in the patients. Left ventricular diastolic function exhibited 24 and 34.5% reductions in left ventricular filling rate and its peak filling rate, respectively, as well as a 44.8% increase in peak filling rate time. To assess the potentialities of myocardial adaptation to a postoperative decrease in blood pressure, artificial hypotension test by using the antihypertensive agent naniprus was performed in 15 patients. This test identified a group of patients with pronounced left ventricular diastolic dysfunctions who required a goal-oriented preoperative preparation. It also defined the principles of this preparation.
