N2 - Background and Methods: Despite the significant progress in the care and outcome of patients with acute myocardial infarction (AMI), the impact of evolving therapies on the incidence and outcome of patients with cardiogenic shock complicating AMI has been questioned. We analyzed trends in the incidence, care and outcome of cardiogenic shock from four national surveys conducted during 1992-1998. Results: Of the 5,351 AMI patients admitted to all coronary care units in Israel, 254 (4.7%) developed cardiogenic shock. The incidence of cardiogenic shock decreased over time (5.8, 5.1, 4.3 and 4.4% for the years 1992, 1994, 1996 and 1998, respectively, p = 0.08). Concomitantly, there was an increase in utilization of coronary angiography, urgent angioplasty and intra-aortic balloon counterpulsation. In addition, there was an increase in hospital use of aspirin, nitrates, ACE inhibitors and β-blockers. Patients with shock were more likely to die within 7 days compared with AMI patients not having shock (65 vs. 4%; p < 0.001). During the study period, the mortality of patients with shock decreased: at 7 days (72% in 1992 to 60% in 1998; p = 0.09), at 30 days (87 to 70%, respectively; p = 0.01) and at 6 months (89 to 77%, respectively; p = 0.02). Both aspirin and angioplasty were independently associated with improved outcome after adjustment for baseline characteristics and study period. Conclusions: Although the mortality rate of cardiogenic shock complicating AMI remains high, the increased utilization of aspirin and angioplasty is associated with improved outcome.
