Long-term cumulative incidence of coronary events and stroke according to incident unexplained syncope- and orthostatic hypotension (OH)-related hospital admission (n=29 129). Kaplan-Meier curves with regard to coronary events (A) and stroke (B) stratified according to incident syncope-related (blue) and OH-related (red) hospital admissions: in both cases showing significantly lower event-free survival rate (Log-rank test: p<0.001) compared with patients never hospitalised for syncope or OH (green). Patients with a first-ever incident syncope-related hospital admission showed a near-significant trend (Log-rank test: p=0.061) towards higher coronary event rate compared with incident OH-related admission. OH-related hospitalisation was associated with a significantly higher risk of stroke (Log-rank test: p=0.017).
