Study Notes

Heart Failure Overview

Heart failure categorized into reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF).
HFrEF commonly caused by coronary heart disease (CHD) and past myocardial infarction.

Causes of HFpEF

Hypertension, particularly prevalent in elderly women, is a frequent cause of HFpEF.

Pharmacological Treatment for HFrEF

ACE inhibitors (ACEIs) are crucial for improving survival and reducing hospitalizations in HFrEF patients.
Major side effect of ACE inhibitors is hyperkalemia, requiring monitoring of potassium levels.

Mineralocorticoid Receptor Antagonists (MRAs)

MRAs block aldosterone's effects, beneficial for HFrEF management.
They are associated with hyperkalemia as a common adverse effect.

Role of Beta-Blockers

Beta-blockers reduce heart rate and inhibit harmful neurohormonal activation.
In the early treatment stages, they can cause bradycardia and low blood pressure.

Signs of Heart Failure

Right-sided heart failure indicated by raised jugular venous pressure (JVP) and peripheral edema.
Left-sided heart failure commonly presents with shortness of breath (orthopnea), especially when lying down.

Diuretics

Used primarily to manage fluid overload in heart failure patients.
Loop diuretics like furosemide are commonly prescribed for this purpose.

SGLT2 Inhibitors

Mechanism of action includes reducing hospitalization and cardiovascular mortality, independent of blood glucose levels.

BNP Levels Monitoring

Elevated brain natriuretic peptide (BNP) levels help assess the severity of heart failure and fluid overload.

Alternative Therapies for ACE Intolerance

Hydralazine combined with nitrates can be alternatives for patients who cannot tolerate ACE inhibitors or ARBs.

Acute Decompensated Heart Failure

Symptoms include severe shortness of breath and lung crackles, requiring immediate attention.

Monitoring for ACE Inhibitors

Essential to monitor serum potassium and renal function (creatinine and eGFR) in patients on ACE inhibitors.

Ventricular Remodeling Prevention

ACE inhibitors and beta-blockers help prevent detrimental ventricular remodeling in heart failure patients.

Amiodarone and Lung Toxicity

Amiodarone can lead to serious lung toxicity, requiring careful monitoring in patients on this medication.

Non-Pharmacological Management

Important management strategy includes reducing fluid and salt intake to mitigate heart failure symptoms.

Heart Failure Causes and Classifications

HFpEF Least Likely Causes: Chronic alcohol abuse is the least likely cause of heart failure with preserved ejection fraction (HFpEF).
HFrEF Mortality Reduction: ACE inhibitors significantly reduce mortality in heart failure with reduced ejection fraction (HFrEF) but lack proven benefits in HFpEF.
Clinical Signs of Heart Failure: Raised jugular venous pressure (JVP) is most indicative of right-sided heart failure rather than left-sided heart failure.

Diuretics in Heart Failure Management

Use with Caution: Over-diuresis in HFpEF patients can decrease cardiac output due to reduced preload.
Electrolyte Monitoring: Important to monitor potassium levels when prescribing ACE inhibitors and mineralocorticoid receptor antagonists (MRAs) due to an increased risk of hyperkalemia.

Heart Failure Therapies and Guidelines

Contraindicated Therapies: Verapamil is contraindicated in HFrEF due to its negative inotropic effects but may be used in HFpEF for rate control.
Beta-Blocker Dosing: Initiating beta-blockers at a low dose in HFrEF is necessary as they may initially worsen heart failure by reducing cardiac output.
Chronic Kidney Disease (CKD) Complications: ACE inhibitors or ARBs can complicate treatment in heart failure patients with CKD due to increased risk of hyperkalemia and renal function worsening.

Specific Drug Actions and Indications

Ivabradine Use in HFrEF: Correctly indicated for patients with a heart rate ≥ 70 bpm, despite being on beta-blockers, but does not reduce overall mortality in heart failure.
Sacubitril/Valsartan Mechanism: Provides benefits in HFrEF by inhibiting the degradation of natriuretic peptides, leading to vasodilation and natriuresis.

Patient Considerations and Drug Classes

Benefits of SGLT2 Inhibitors: Particularly beneficial in heart failure patients with type 2 diabetes as they reduce hospitalizations and improve cardiovascular outcomes.
Preferred Heart Rate Control in Atrial Fibrillation: Carvedilol is preferred for controlling heart rate in heart failure patients with atrial fibrillation due to mortality benefits.
ARNI Monitoring Needs: Regular monitoring for hypotension is required due to common adverse effects associated with sacubitril/valsartan.

Contraindications and Early Treatment Benefits

Beta-Blocker Contraindications: They may exacerbate fluid retention in patients with decompensated heart failure.
ACE Inhibitors/ARBs Justification: Recommended in early stages of heart failure to prevent progression to symptomatic heart failure by improving cardiac remodeling.
