NT-proBNP and Major Adverse Cardiovascular Events in Patients with ST-Segment Elevation Myocardial Infarction Who Received Primary Percutaneous Coronary Intervention: A Prospective Cohort Study

Table 4

Piecewise linear regression model was used to detect the association of Log2 NT-ProBNP and MACE according to the Log NT-proBNP cutoff points.

Cutoff points	Hazard ratio	95% CI	value
≤11.66	1.07	0.84–1.36	0.5730
>11.66	3.47	2.06–5.85	<0.0001

Adjusted variables: sex, age, number of implanted stents, number of balloons used, hypertension, hyperlipidemia, diabetes, smoking, time from symptom onset to balloon dilatation, time from admission to balloon dilatation, Killip class, post-PCI TIMI grade, and TIMI risk score.
