Management of diastolic heart failure following cardiac surgery

Abstract

A considerable number of patients who undergo cardiac surgery have a variety of comorbid conditions that includes diastolic dysfunction. Abnormalities of diastolic function may lead to diastolic heart failure that can complicate their postoperative course. This form of failure occurs more commonly in patients with hypertensive or valvular heart disease, diabetes mellitus, myocardial ischaemia, as well as in hypertrophic or restrictive cardiomyopathy, and is more prevalent in the elderly. In spite of it being a common cause of heart failure it remains underreported in the postoperative heart. We reviewed relevant literature analysing the different therapeutic approaches and formulated a management plan for diastolic heart failure in the postoperative heart in the intensive care environment based on the most current understanding of this form of cardiac failure.
