Specific Considerations With Cardiac Disease - Congestive Heart Failure

Heart failure results from impairment of ventricular systolic or diastolic function. Heart failure manifests as dyspnea, fatigue, decreased exercise tolerance, and pulmonary or peripheral edema. Heart failure can be classified into two categories: (1) heart failure with reduced ejection fraction (HFrEF) that is associated with variable degrees of LV enlargement and depressed ventricular ejection and (2) heart failure with preserved ejection fraction (HFpEF) in which diastolic dysfunction is pronounced.
