OESIL Risk Score (syncope 12-month mortality)

OESIL risk score (Colivicchi 2003): one point each for age > 65, cardiovascular history, syncope without prodrome, and an abnormal ECG; the 0-4 total maps to rising 12-month total mortality.

Example

Age > 65 years
Yes
Cardiovascular disease in history
Yes

Result: OESIL 2/4: 12-month total mortality 19.6% (high-risk band; rises sharply at >= 2).

The tool opens with these values already filled in. Replace them with your own.

What the result means

Score 0-4
one point each for age > 65, cardiovascular disease history, syncope without prodrome, and an abnormal ECG.
Mortality
12-month total mortality 0 = 0%, 1 = 0.8%, 2 = 19.6%, 3 = 34.7%, 4 = 57.1%; rises sharply at >= 2. Cross-links rose-syncope, egsys.
