In-hospital and long-term outcome after reoperative coronary artery bypass graft surgery

Increasingly over the past several years, patients have returned after coronary surgery for reoperative procedures, and the experience has become substantial. In this report, we describe immediate- and long-term outcomes after reoperative coronary artery bypass graft surgery. The source of data was the clinical database at Emory University. The surgical procedure and statistical methods were standard. Data were collected prospectively and entered into a computerized database. Follow-up was by letter, telephone, or hospital records documenting additional events resulting in readmission. In-hospital correlates of survival were determined by logistic regression, and long-term correlates were determined by Cox model analysis. There were 2030 patients with a mean age of 61 and a mean of 7.8 +/- 4.1 years since the first surgery. The mean ejection fraction was close to 50%, and the majority had three-vessel or left main disease. Urgent or emergency surgery was required in 16.6%. The internal mammary was used in 60.1%. Q-wave myocardial infarctions occurred in just over 5%. Neurological events increased from 1.2% at less than age 50 to 4.1% at more than age 70. The hospital mortality increased from 5.7% at less than age 50 to 10% at m...Continue Reading
