Structural heart disease as the cause of syncope

摘要: We described the clinical evolution of patients with structural heart disease presenting at emergency room syncope. Patients were stratified according to their syncope etiology and available scores for prognostication. Cox proportional hazard models used investigate relationship between event-free survival. Of 82,678 visits during study period, 160 (0.16%) there due syncope, having a previous diagnosis disease. During median follow-up 33.8±13.8 months, mean age qualifying event was 68.3 years 40.6% male. Syncope vasovagal in 32%, cardiogenic 57%, orthostatic hypotension 6%, unknown causes 5% patients. The primary composite endpoint death, readmission, visit 30 days 39.4% 60.6% (P<0.001). Primary endpoint-free survival lower (HR=2.97, 95%CI=1.94-4.55; P<0.001). analyzed diagnostic performance area under curve (AUC) did not help differentiate an increased risk adverse events. differential is important, because postural have better less probability or hospital readmission. are reliable tools prognosis this specific patient population.
