高血压与缺血性心脏病常同时存在,高血压可促成或使动脉硬化性心脏病恶化,但降低血压曾提示可促发冠心病之心绞痛。作者用随机交叉对照试验观察了心痛定及心得安,联台或分别应用时对缺血性心脏病血压与心率的效应。 Hypertension and ischemic heart disease often exist at the same time, high blood pressure can contribute to or make atherosclerotic heart disease worse, but lower blood pressure has been prompted to trigger angina pectoris. The authors used a randomized controlled cross-over trial to observe the effects of nifedipine and propranolol, co-administered or separately on blood pressure and heart rate in patients with ischemic heart disease.
