Insights

Sorafenib, a cancer drug, can rarely cause severe heart failure. Prompt recognition and multidisciplinary care are crucial for managing this rare but serious side effect in hepatocellular carcinoma patients.

Area of Science:

  • Oncology
  • Cardiology
  • Pharmacology

Background:

  • Sorafenib is a key treatment for unresectable hepatocellular carcinoma.
  • Sorafenib's known side effect is cardiotoxicity, primarily hypertension.
  • Severe, symptomatic heart failure is an uncommon sorafenib-associated toxicity.

Observation:

  • A patient with multiple comorbidities developed acute heart failure with reduced ejection fraction (HFrEF) and atrial fibrillation.
  • Symptoms of dyspnea and reduced left ventricular ejection fraction (26%) emerged three years into sorafenib treatment.
  • The cardiac event was attributed to sorafenib, despite prior good tolerability.

Findings:

  • Sorafenib treatment led to acute, symptomatic heart failure (NYHA class IV) with severe left ventricular dysfunction.
  • The cardiotoxicity was partially reversible upon sorafenib discontinuation and optimized cardiac management.
  • This case highlights a rare but severe manifestation of sorafenib-induced cardiotoxicity.

Implications:

  • Early identification and aggressive management of sorafenib-induced cardiotoxicity are vital.
  • A multidisciplinary approach involving oncologists and cardiologists is essential for patient outcomes.
  • This case underscores the need for vigilant cardiac monitoring in patients receiving sorafenib for liver cancer.

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Heart Failure Drugs: Inotropic Agents

Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
