Treatment strategies for acute myocardial infarction complicated by cardiogenic shock in a community hospital.

The risks and benefits of three treatment strategies were examined in 64 consecutive patients with acute myocardial infarction and cardiogenic shock. Thirteen patients received thrombolytic therapy (group 1), 29 patients received intra-aortic balloon pump counterpulsation support (group 2), and 22 patients were treated with combined thrombolytic therapy and intra-aortic balloon pump counterpulsation support (group 3). The groups were similar in regard to age, sex, medical history, hemodynamic data, and extent of coronary artery disease. Survival was improved in patients treated with combined thrombolytic therapy and intra-aortic balloon pump counterpulsation support (group 1, 23 percent; group 2, 28 percent; and group 3, 68 percent; p=0.0049). Seven percent of the patients who remained at the community hospital survived vs 69 percent who were transferred to a tertiary care center (p
