APACHE II score (10-pt increment) 5.7 (2.6–12.6) 3.9 (1.3–11.8) 4.9 (2.5–9.9) 3.5 (1.2–10.1)
Mechanical ventilation Not estimable1 Not estimable1 17.3 (2.2–134.8) 7.4 (0.7–79.9)
Inotropes or vasopressors 78.2 (9.6–640.9) 23.6 (2.5–219.3) 17.0 (5.3–54.5) 6.3 (1.3–29.3)

Elevated cTn 20.3 (2.6–160.4) 2.8 (0.1–70.6) 31.3 (4.0–244.4) 27.3 (1.7–449.4)

  1. APACHE = Acute Physiology and Chronic Health Evaluation; CI = confidence interval; cTn = cardiac troponin; ICU = intensive care unit; MI = myocardial infarction; OR = odds ratio; 1Not estimable because all patients were either ventilated or died or both.
