title: [Bolus nicardipine in the hemodynamic assessment for heart transplantation of patients with severe failure of ischemic origin and high pulmonary resistance].
abstract: Nicardipine i.v. bolus (5 mg/5 min) was administered in the pulmonary artery trunk in 13 patients (2 f, 11 m), mean age 48 +/- 8 yrs, affected by ischemia congestive heart failure, with pulmonary hypertension (pulmonary vascular resistances greater than 6 U.W. and/or systolic pulmonary artery blood pressure greater than or equal to 60 mmHg). The vasodilatation induced by nicardipine caused a rapid improvement of all hemodynamic parameters, with a significant reduction of systemic and pulmonary pressures and resistances; in addition, cardiac output increased significantly. Even if heart rate decreased and mean right atrial pressure fell, their variation did not reach statistical significance. These beneficial effects are attributable to the vasodilator action of nicardipine on the systemic and pulmonary vascular districts. Therefore, in the hemodynamic evaluation of patients with ischemic cardiomyopathy proposed for heart transplantation, we propose the employment of nicardipine in testing the vascular reactivity in cases with secondary pulmonary hypertension.
