A Nomogram Based on Apelin-12 for the Prediction of Major Adverse Cardiovascular Events after Percutaneous Coronary Intervention among Patients with ST-Segment Elevation Myocardial Infarction

Table 2

Comparisons of C-indexes of the present risk score with other already available risk scores to predict major adverse cardiovascular events in the evaluation and validation data sets.

Risk scores	Evaluation cohort		Validation cohort
	C-index	95%CI	C-index	95%CI
Apelin-12 based nomogram	0.758	0.707–0.809	0.763	0.689–0.837
TIMI risk index	0.625	0.568–0.682	0.587	0.489–0.685
PAMI risk score	0.652	0.593–0.711	0.657	0.559–0.755
C-ACS risk score	0.638	0.579–0.697	0.614	0.514–0.714

TIMI = thrombolysis in myocardial infarction; PAMI=primary angioplasty in myocardial infarction; C-ACS =Canada acute coronary syndrome; CI = confidence interval.
