Fig. 2

Kaplan-Meier survival analysis showing the probability of being free from recurrent myocardial infarction in patients with STEMI and NSTEMI with and without pulmonary infection. (A) STEMI patients: red curve indicates those with pulmonary infection, blue curve indicates those without. Pulmonary infection significantly reduces the probability (P = 0.0000). (B) NSTEMI patients: red curve indicates those with pulmonary infection, blue curve indicates those without. Pulmonary infection significantly reduces the probability (P = 0.0000).
