Harwin B, et al. - Data from the Humana database (PearlDiver) were examined from 2007 to 2016 of 105,505 subjects who underwent lumbar spine surgeries by the researchers in order to discover the association between lumbar surgeries, preoperative diagnoses (risk factors), and myocardial infarction. Within 30 days of surgery, a total of 644 subjects experienced postoperative myocardial infarction. Subjects who underwent fusion and non-fusion procedures exhibited significantly various rates of postoperative myocardial infarction. A considerable increase in incidence was demonstrated by the male subjects, elderly individuals, and subjects with a Charlson comorbidity index >3. Risk ratios from 0.01 to 1.85 were shown by the cases with preoperative risk factors like high cholesterol, obesity, depression, congestive heart failure, hypertension, and hypotension. Hence, a notable impact on the incidence of postoperative myocardial infarction was noted in the preoperative risk factors, patient demographics, and procedure type.
