Hydralazine-Associated Pericardial Effusion Causing Cardiac Tamponade Without Hypotension

Key Result

Hydralazine can induce pericardial effusion resulting in cardiac tamponade that presents atypically without hypotension.

Key Points

• To highlight the relationship between hydralazine use and drug-induced pericardial effusion leading to cardiac tamponade.
• Identified a case of cardiac tamponade linked to hydralazine use
• Assessed the patient's clinical presentation and symptoms
• Examined the role of hydralazine in autoimmune phenomena
• The patient experienced cardiac tamponade without hypotension
• Hydralazine was implicated as the causative agent of pericardial effusion
• Findings suggest that cardiovascular consequences of hydralazine are under-recognized
