This chapter explores acute diastolic heart failure, which presents a difficult management scenario in the early post–cardiac surgery period. Initial diagnosis is assisted by knowledge of the patient's medical history and intraoperative course. It is made using both clinical and echocardiographic parameters. Diastolic dysfunction often remains asymptomatic until late in the disease process. When it presents clinically, it can be associated with an abnormal ejection fraction or, more commonly, with preserved ejection fraction. The diagnosis of diastolic dysfunction requires 3 conditions: the presence of signs and/or symptoms, normal left ventricular systolic function, and increased diastolic filling pressures. Treatment for diastolic heart failure includes fluid therapy, diuretics, vasoactive medicines, control of ventricular rate in atrial fibrillation, and amiodarone.
