目的：观察米力农、多巴酚丁胺联用治疗重度慢性充血性心力衰竭（ＣＨＦ）的疗效。方法：将７０例随机分为治疗组和对照组，两组常规治疗相同（洋地黄、利尿剂、血管转换酶抑制剂）；前者联用米力农、多巴酚丁胺，后者单用多巴酚丁胺，５～７ｄ为一疗程。结果：两药联用治疗重度ＣＨＦ总有效率９４．３％，单用多巴酚丁胺总有效率７７．１％，两组疗效差异有显著性（Ｐ＜０．０５）。结论：米力农、多巴酚丁胺联用治疗重度ＣＨＦ有良好疗效。
Objective: To observe the efficacy of milrinone combined with dobutamine in the treatment of severe chronic congestive heart failure (CHF). Methods: Seventy patients were randomly divided into treatment group and control group. The two groups were given the same routine treatment (digitalis, diuretic and angiotensin converting enzyme inhibitor). The former was combined with milrinone and dobutamine, Dobutamine, 5 ~ 7d for a course of treatment. Results: The total effective rate of combined treatment of two drugs was 94.3%, and the total effective rate of dobutamine alone was 77.1%. The difference between the two groups was significant (P <0.05). Conclusion: Milrinone, dobutamine combined with severe CHF have a good effect.
