The ICU length of stay and extubation time of patients who died were statistically significantly longer than those of surviving patients (p < 0.01).The incidence of pneumonia in patients who died was statistically significantly higher than in those who survived (p < 0.01; Table 3).There was also a significant difference in pre- and postoperative values of creatinine kinase-MB (CK-MB) and troponin between living and dying patients (Table 4). The gene discussed is MB; the disease is susceptibility to pneumonia measurement.
