Study Notes
Aortic Regurgitation Management
- Symptomatic AR requires aortic valve replacement surgery.
- Asymptomatic severe AR indicated by LV failure; utilize the SS-50 rule: EF ≤ 55% and LVEDD ≥ 50%.
- Acute AR causes include aortic dissection (chest pain), infective endocarditis, rupture of the sinus of Valsalva (right heart failure), and trauma.
- Acute regurgitation leads to increased left ventricular end-diastolic pressure (LVEDP), resulting in pulmonary edema and LV failure.
Heart Failure Overview
- Defined as a complex clinical syndrome with structural or functional cardiac disorders impairing the ventricle's ability to pump blood.
- Structural issues may include left ventricular hypertrophy (LVH) while functional may involve arrhythmias like atrial fibrillation.
Heart Failure Classification
- Types include HFrEF (reduced EF < 40%), HFpEF (preserved EF ≥ 50%), HFMEF (mid-range EF 40-50%), and ADHF (acute decompensated heart failure).
NYHA Classification
- Class I: Symptoms with ordinary activity, negligible mortality.
- Class II: Symptoms with ordinary physical activity, risk of sudden cardiac death.
- Class III: Symptoms with less than ordinary activity.
- Class IV: Symptoms at rest, indicative of severe LV failure.
Stages of Heart Failure
- Stage A: No symptoms, only risk factors (e.g., hypertension, diabetes).
- Stage B: No symptoms, structural heart disease present (e.g., LVH following hypertension).
- Stage C: Most common stage, symptomatic patients.
- Stage D: Refractory heart failure, unresponsive to medical therapy.
HFrEF Clinical Features
- Symptoms of systolic failure due to decreased cardiac output include fatigue, decreased urine output, cool extremities, cyanosis, altered mentation, and cardiomegaly.
- S3 heart sound may be present, indicating dilated LV.
RAAS and ADH in Heart Failure
- RAAS activation leads to vasoconstriction and increased afterload, while aldosterone promotes sodium and water retention.
- ADH causes free water retention leading to hyponatremia, while natriuretic peptides inhibit RAAS and promote salt and water excretion.
Heart Failure Treatment
- Treatment logic involves blocking pathways of sympathetic activity, RAAS, and the degradation of natriuretic peptides.
- Beta blockers (e.g., metoprolol, bisoprolol, carvedilol) reduce sympathetic overactivity.
- ACE inhibitors (e.g., ramipril, perindopril) and ARBs offer a class effect in management.
Diastolic Failure Symptoms
- Characterized by concentric LVH and insufficient dilation, leading to increased end-systolic volume and elevated pressures (LVEDP, LAP).
- Dyspnea is a predominant symptom, often associated with pulmonary congestion and may present as orthopnea or paroxysmal nocturnal dyspnea.
Right Heart Failure Overview
- Most commonly due to left heart failure, resulting in increased right ventricle end-diastolic pressure (RVEDP).
- Signs include abdominojugular reflex, ascites, edema, hepatomegaly, and increased jugular venous pressure.
Common Causes of Heart Failure
- Dilated cardiomyopathy (often genetic), ischemic cardiomyopathy (post-myocardial infarction), valvular heart disease (severe AR, AS, MR), and congenital heart disease.
Framingham Diagnostic Criteria
- Major criteria include acute pulmonary edema, cardiomegaly, and jugular venous pressure.
- Minor criteria include ankle edema, dyspnea on exertion, and nocturnal cough.
HFpEF/HFNEF Pathophysiology
- Driven by comorbidity-related microvascular inflammation leading to left ventricular dysfunction and diastolic dysfunction, often resulting in atrial fibrillation.
Key Terminology
- Bendopnea: Symptoms worsen upon bending due to increased venous return.
- Trepopnea: Difficulty breathing when lying on one side, often preferring the right side.
- Platypnea: Breathlessness when upright, relieved by lying down.
Refractory Heart Failure Management
- Includes ARNI with beta blockers as first-line therapy; consideration of diuretics if patient is not euvolemic.
- If symptomatic, consider advanced therapies like cardiac resynchronization therapy or implantable devices depending on QRS width.
Fantastic Four for Heart Failure
- ARNI, beta blocker, aldosterone antagonist (e.g., finerenone), and SGLT2 inhibitors (e.g., empagliflozin, dapagliflozin) provide mortality benefits.
Heart Failure with Renal Failure
- Managed with hydralazine and nitrates to address congestion while considering diuretic therapy and subsequently introducing beta-blockers.
