UNASSIGNED: Cardiac tamponade is a life-threatening condition, whose current specific cause and outcome are unknown. Our purpose was to analyze it. We performed a retrospective observational study with prospective follow-up data including 136 consecutive @entity1 admitted with diagnosis of @entity2293 , from 2003 to 2013. We thoroughly recorded variables as clinical features, @entity5173 /pericardiocentesis, fluid characteristics, and long-term events (new @entity204 ). The median age was 65    17  years (55% @entity1 ). In the baseline characteristics, 70% were no smokers, 12% were on anticoagulation, and 13 had suffered a previous @entity583 . In the preceding month, 15 @entity1 had undergone a cardiac catheterization, 5 cardiac surgery, and 5 pacemaker insertion. Fever was observed in 16% of @entity1 and 21% displayed other inflammatory symptoms. In 81% of @entity1 , pericardiocentesis was needed. The fluid was hemorrhagic or a transudate in the majority, with positive cytology in 15% and bacteria in 3.7%. Main causes were @entity5 (32%), @entity281 (24%), idiopathic (16%), iatrogenic (15%), @entity1188 (7%), uremic (4%), and other causes (2%). After a maximum follow-up of 10.4  years, @entity2293 recurred in 10% of the cases (62% in the neoplastic group) and the 48% of @entity1 died (89% in the neoplastic cohort). In conclusion, most @entity2293 are due to @entity5 , having this specific cause a poorer outcome, probably as a manifestation of an advanced disease. The rest of causes, after an aggressive intensive management, have a good prognosis, especially the iatrogenic.
