Study Notes
Heart Failure: Pathophysiology, Classification, Symptoms, and Pharmacotherapy
- Heart failure is the inability of the heart to pump blood at a rate sufficient to meet the body’s metabolic demands, and it can be systolic or diastolic.
- Common causes of heart failure include ischemic heart disease, diabetes mellitus, and chronic hypertension, along with other factors such as neurohormonal imbalances and proinflammatory cytokines.
- Compensatory mechanisms, such as activation of the sympathetic nervous system and the renin-angiotensin aldosterone system, kick in as cardiac function decreases to maintain cardiac output.
- The New York Heart Association Functional Classification categorizes heart failure into four stages based on the limitations of physical activity.
- Signs and symptoms of heart failure include bloating, anorexia, peripheral edema, dyspnea on exertion, and bibasilar rales, among others.
- Standard first-line therapies for heart failure include ACE inhibitors, ARBs, beta blockers, diuretics, and SGLT2 inhibitors, among others.
- The pharmacotherapy goals for heart failure are to improve quality of life, slow disease progression, prolong survival, and treat underlying conditions such as hypertension, diabetes, and dyslipidemia.
- Most patients with heart failure are managed with a combination of three drugs: diuretics, ACE inhibitors or ARBs, and beta blockers.
- ACE inhibitors are the cornerstone of therapy for heart failure, reducing preload, afterload, and inhibiting the effects of angiotensin II on the myocardium.
- ARBs are used for heart failure patients intolerant of ACE inhibitors, and Entresto (sacubitril and valsartan) is a preferred first-line agent for heart failure.
- Loop diuretics, such as furosemide, are preferred for decreasing fluid retention in heart failure and are used in combination regimens for patients with evidence of volume overload.
- Beta blockers play a role in heart failure by reversing sympathetic nervous system and neurohormonal activation, and specific types such as bisoprolol, metoprolol succinate, and carvedilol are used for heart failure.
