Heparin-Induced Hyperkalemia: Mechanisms, Risk Factors, and Clinical Implications
Heparin-induced hyperkalemia is reversible upon drug discontinuation. Aldosterone production typically recovers within days to weeks after stopping heparin. However, unrecognized severe hyperkalemia can lead to cardiac arrest and death. Therefore, awareness and monitoring are critical, particularly in hospitalized patients receiving therapeutic-dose heparin. heparin cause hyperkalemia
Heparin, a widely used anticoagulant, is essential in the prevention and treatment of thromboembolic disorders such as deep vein thrombosis, pulmonary embolism, and acute coronary syndromes. While its anticoagulant effects are well-recognized, a less familiar but clinically significant adverse effect is hyperkalemia—an elevated serum potassium level that can lead to life-threatening cardiac arrhythmias and muscle weakness. Although heparin-induced hyperkalemia is often mild and asymptomatic, it can become severe, particularly in patients with underlying risk factors. This essay examines the pathophysiology, clinical presentation, risk factors, and management strategies of hyperkalemia caused by heparin and its low-molecular-weight derivatives. it can become severe
