Heart Failure: Dyspnea and fatigue are main symptoms.
-Heart Failure with reduced Ejection Fraction: Ejection Fraction is < 40 percent.
-Heart Failure with preserved Ejection Fraction, EF >50 percent
-Causes: Hypertension, Amyloidosis, Sarcoidosis, Hemochromatosis, Pericarditis, Valvular disease, atrial myxoma.
-50 of patients with symptoms of heart failure has preserved Ejection Fraction.
-NYHA Functional Classification:
Class 1: No limitation of physical activity.
Class 2: Slight limitation of physical activity.
Class 3: Marked limitation of physical activity.
Class 4: Unable to carry on any physical activity without symptoms of HF. Symptoms of HF at rest.
-BNP: Brain Natriuretic Peptide is secreted from the ventricles in response to ventricular volume expansion and pressure overload. BNP less than 100 excludes HF as cause of shortness of breath.
-Treatment:
Preload Reduction: Diuretics, Nitrates
Afterload Reduction: ACE inhibitors, ARBs, Hydralazine, Nitrates.
Sympathetic blockade: Beta blockers
Aldosterone-antagonist therapy: Spironolactone, Eplerenone.
-Renin-Angiotensin System Inhibition by ACE inhibitors and ARBs. Both reduce mortality and morbidity.
-Beta Blockers: Should be started when the patient is stable and euvolemic. There is no absolute threshold ejection fraction where beta-blockers may not be used.
-Spironolactone: reduces mortality, improves ejection fraction.
-Entresto: Valsartan plus Sacubitril can reduce morality.
