Abstract

We report a case of a 75-year-old male with history of lung adenocarcinoma who presented with shortness of breath and frequent episodes of cough-induced syncope. A large pericardial effusion was found on echocardiogram suggestive of cardiac tamponade. Pericardiocentesis was done which improved the dyspnea and eventually resolved the syncope. There are only two other cases reported in the literature with cough-induced syncope in the setting of pericardial effusion or cardiac tamponade. Our clinical vignette also highlights the importance of pulsus paradoxus identification in patients with cough induced syncope to rule out cardiac tamponade since this is the most sensitive physical finding for its diagnosis.

Keywords: Cardiac tamponade, Cough-induced syncope, Pericardial effusion

Core tip: Cough-induced syncope should be a hint towards the consideration of either pericardial effusion or cardiac tamponade. Aside from the medical history and the diagnostic imaging modalities to include echocardiogram and chest computed tomography, clinical evaluation to explore pulsus paradoxus is imperative which has a high sensitivity in the diagnosis of cardiac tamponade. Timely diagnosis of cardiac tamponade because of these clues translate into prompt intervention to prevent the deleterious complications associated with it.
