[Syncope: epidemiological characteristics of a hospital series].
Three hundred hospital patients with syncope (193 males and 107 females, mean age 61 +/- 17 years) were prospectively evaluated with a standard protocol. Associated diseases were found in 76.7% of cases. The incidence of heart diseases was 50.8% in males vs 32.7% in females (p less than 0.003). The cause of syncope was diagnosed in 250 patients (84%). The diagnosis was made at initial evaluation in 101 patients (group A); in the remaining patients (group B), no diagnosis was made in 25% (16.6% of the overall series) despite a wide array of investigations. Syncope due to arrhythmia was diagnosed in 57.6% (group A: 91.1% group B: 40.7; p less than 0.0001); cardiac syncope not due to arrhythmia was diagnosed in 4%, and other types of syncope in 21.6% (group A; 6.9%; group B: 29.1%; p less than 0.0001). It is concluded that a) the hospital population of patients with syncope represents a subgroup of advanced age and a high incidence of associated diseases; b) one third of patients were diagnosed at the initial evaluation, whereas in 25% of the remaining ones no diagnosis was obtained, and c) in these patients, arrhythmia is the most likely cause of syncope.
