近十年的临床实践证明,血管扩张药是治疗心力衰竭的有效方法。由于慢性严重的顽固性心力衰竭患者病理生理上突出表现为心脏容量负荷(前负荷)及后负荷明显增加,因此应用血管扩张药后可使心室前后负荷减轻,从而使心脏功能改善。即使那些传统强心及利尿剂无显效的“难治性(顽固性)心衰”患者,加用血管扩张药后往往可有显著改善心衰的效果。本文重点讨论药物选用的某些问题。治疗慢性心力衰竭常用的血管扩张药有多种,对心力衰竭患者可产生短期及长期的效果,但目前尚没有一种药物能完全代替另外的血管扩张药,故临床医
Nearly a decade of clinical practice has proved that vasodilators are effective methods of treating heart failure. Due to the pathophysiology of chronic severe intractable heart failure manifested as cardiac capacity load (preload) and afterload increased significantly, so the application of vasodilator drugs before and after the ventricle can reduce the load, so that heart function improved. Even in patients with “refractory (refractory) heart failure,” who have no traditional cardiomyopathy and diuretics, adding a vasodilator often results in a significant improvement in heart failure. This article focuses on some aspects of drug selection. Treatment of chronic heart failure commonly used in a variety of vasodilators, heart failure patients can produce short-term and long-term results, but there is no one drug can completely replace another vasodilator, so clinicians
