Comprehensive assessment of heart failure in patients with preserved ejection fraction undergoing coronary bypass grafting.
Although coronary artery bypass grafting is expected to improve the outcomes of patients with advanced coronary artery disease, whether prognosis is different according to preoperative diastolic function remains unclear. This study sought to evaluate the prognostic implications of preoperative heart failure with preserved ejection fraction in patients undergoing coronary artery bypass grafting. ⋯ On the basis of noninvasive assessment using Heart Failure Association Pretest Assessment, Echocardiography and Natriuretic Peptide, Functional Testing, Final Etiology score, a substantial proportion of patients with coronary artery disease who underwent coronary artery bypass grafting had preoperative heart failure with preserved ejection fraction. Preoperative heart failure with preserved ejection fraction was significantly associated with a decrease in the 5-year survival after successful coronary artery bypass grafting.
