阻塞性冠状动脉疾病患者,可因低心排出量和肺充血而使活动受到限制,对于已用洋地黄、利尿剂和硝酸酯药物而仍有心力衰竭症状的患者,推荐应用降低后负荷的药物。肼苯哒嗪对严重心力衰竭患者可产生有益的血液动力学改变,特别是降低左室充盈压,增加每次心搏量及心排出量,本文旨在评价口服肼苯哒嗪对冠状动脉疾病并有左室功能失调患者的血液动力学作用。方法:12例心功能Ⅲ-Ⅳ级的冠状动脉疾病患
Patients with obstructive coronary artery disease may have limited activity due to low cardiac output and pulmonary congestion, and for patients with heart failure who have been treated with digitalis, diuretics, and nitrates, the recommendation is to use a drug that reduces postload . Hydralazine can produce beneficial hemodynamic changes in patients with severe heart failure, in particular, reduce left ventricular filling pressure and increase each stroke and cardiac output, the purpose of this paper is to evaluate the efficacy of oral hydralazine on coronary artery disease And left ventricular dysfunction in patients with hemodynamic effects. Methods: Twelve patients with coronary artery disease with grade Ⅲ-Ⅳ cardiac function were involved
