Table 2. Events at one year according to Essen score risk categories.

	Events	HR (95% CI)	P-value
*Referred to a combined vascular event was defined as myocardial infarction, recurrent stroke and vascular death, whenever come first. **Referred to a cardiac event was defined as myocardial infarction, heart failure and cardiac death, whenever come first. CI: confidence interval; HR: hazard ratio.
