Impact of preoperative anemia in ischemic cardiomyopathy with or without coronary artery bypass grafting.

ABSTRACT:

Background

Whether the preoperative anemia affects the prognosis and the therapeutic choice between coronary artery bypass grafting (CABG) or medical therapy alone in patients with ischemic cardiomyopathy (ICM) remains unclear. We assess the influence of preoperative anemia on long-term outcomes in ICM patients treated with medical therapy alone with or without CABG.

Methods

Patients with preoperative hemoglobin were included from the Surgical Treatment of Ischemic Heart Failure (STICH) trial. The primary outcome was long-term all-cause mortality.

Results

A total of 1,209 patients were enrolled, with 320 (26.5%) patients with anemia, and 889 (73.5%) without anemia. The median follow-up time was 9.7 years. Compared with patients without anemia, patients with anemia had
