Survival of the myocardical revascularization implanted to the affiliated to the Obligatory Plan of Health (OPH) of Susalud EPS, Colombia, 1999-2004

Objective: to describe the survival of myocardical revascularization in patients affiliated to the obligatory plan of health (OPH) of Susalud company in five Colombian cities between 1999 and 2004. Materials and methods: 720 myocardical revascularizations were considered from which their characteristics were included in a database of Susalud. A life table and the survival function curve of the myocardical revascularization were built. The association of this information with variables of person by Kaplan Meier’s method and the log rank test was explored. Results and conclusions: from the moment of the surgery until six years later the durability of the myocardical revascularization reached 86.3%: 92,8% for men and 72.9% for women. The probability of fault of the myocardical revascularization presented a remarkable reduction during the first 9 months. Since this time on it had little variability until the sixth period (53.1 months). In the next period it had an important increase (62-70.9 months). A high probability of fault in the early postsurgery period as well as at the end of the study is pointed out. The durability of the myocardical revascularization was also associated with, and it was found that 50% of the implants that fail in women doubled durability of those implanted to men. The present research can be a starting point for future investigations on survival of the myocardical revascularization that include clinical variables that can influence in it
