AIM: The aim of this study was to investigate effects of congestive heart failure on coronary revascularization results in patients with left ventricular dysfunction and operated for elective coronary revascularization.
METHODS: The data were collected retrospectively from 126 consecutive patients with left ventricular dysfunction caused by coronary artery disease between January 2007 and January 2012. Patients admitted to hospital with angina complaints without congestive heart failure symptoms were group 1 and patients with severe congestive heart failure symptoms were group 2. Accompanying diseases, postoperative complications and mortality were recorded.
RESULTS: There were 66 patients in group 1 and 60 patients in group 2. Postoperative maximal inotropic support was necessary in 24 (36.4%) patients in group 1 for a mean duration of 1.6±0.9 days and in 34 (56.7%) patients in group 2 for a mean duration of 2.9±0.7 days. The proportion of patients with postoperative stay at the intensive care unit longer than 48 hours was significantly higher in group 2 compared to group 1. (p=0.0001) Hospital mortality was significantly higher in group 2 compared to group 1. (p=0.0001)
CONCLUSION: Congestive heart failure aggravates the outcome after coronary artery bypass surgery in patients with left ventricular dysfunction.
