Thirty-five Yorkshire cross swine underwent percutaneous myocardial infarction with ethanol ablation of the circumflex or obtuse marginal (OM) arteries. Echocardiography was performed at various intervals to assess the development of ischemic mitral regurgitation (IMR) and cardiac function. Swine that developed significant IMR were scheduled for mitral valve operations, which were performed using cardiopulmonary bypass. Echocardiographic analysis was conducted to evaluate parameters such as ejection fraction, mitral regurgitation severity, and wall motion.
This dataset is the result of a randomized clinical trial to determine the effect of cognitive therapy and selective use of SSRIs on the morbidity and mortality of depressed myocardial infarction patients. Recruitment of participants took place between October 1996 and October 1999 with the trial terminating in 2001. Data were collected for 2481 study participants, 1243 of whom received usual care and 1238 underwent intervention treatment. The dataset includes demographic information, medical characteristics and history, physical examination, current medications, clinical values, and treatment data and outcomes. A total of 38 different files may be combined based on type of data needed.
