          We investigated the incidence and determinants of early and late repeat hospitalization for cardiac causes in 378 patients following myocardial revascularization [199 coronary balloon angioplasty (PTCA), 179 coronary bypass surgery (CABG)] in a single cardiovascular center and followed for a median period of 13 years. Data were available for repeat rehospitalization in 91% and for mortality in all. Patients in the upper quartile for repeat hospitalization (≧4 rehospitalizations) were defined as having multiple repeat hospitalizations. In the PTCA cohort, the rehospitalization rate was high (48%) in the first year, partly due to restenosis and to a group of patients who underwent planned repeat angiography, and then 15–26% annually. In the surgical cohort, annual repeat hospitalization was 8–12% during the first 4 years, but increased to a level similar to that in PTCA patients (19–26%) in the second half of the follow-up period. Independent predictors of multiple (≧4) repeat hospitalizations included systemic hypertension (odds ratio 2.4, 95% CI 1.4–4.0), incomplete revascularization (odds ratio 2.0, 95% CI 1.1–3.4) and less extensive (<3 vessels) disease at the time of the index procedure (odds ratio 2.0, 95% CI 1.1–3.4). Predictors of repeat hospitalization were different from those of mortality (diabetes mellitus, 3-vessel disease). Late repeat hospitalizations after myocardial revascularization impose a considerable burden on the patient and the health care system, and represent an issue which should be better addressed.

          Predictors of Death and Other Cardiac Events within 2 Years after Coronary Artery Bypass Grafting

          Results: In 1,841 patients who underwent coronary artery bypass grafting (CABG) we evaluated risk indicators for death and other cardiac events during 2 years of follow-up. Independent predictors of death were: a history of congestive heart failure, diabetes mellitus and renal dysfunction prior to CABG. Independent predictors of death, acute myocardial infarction (AMI), CABG or percutaneous transluminal coronary angioplasty (PTCA) were: a small body surface area, a history of congestive heart failure, diabetes mellitus and smoking prior to CABG. Independent predictors of death, AMI, CABG, PTCA or rehospitalization for a cardiac reason were: angina functional class, previous AMI, a history of congestive heart failure and renal dysfunction prior to CABG. Conclusion: When using various definitions of a cardiac event after CABG, various risk indicators for death or such an event can be found. Our data suggest that anamnestic information prior to CABG indicating a depressed myocardial function or severe myocardial ischemia are more important predictors of outcome than the information gained from cardioangiography.
