Patients with cardiac syncope appear to do worse than patients with noncardiac syncope. Soteriades et al followed 7814 patients with syncope for 17 years and found a higher mortality for patients with cardiac syncope than for those with noncardiac syncope. [14]  Suzuki et al studied 912 patients with syncope for an average of 3 years and found the same result. [15]
