Of those patients, they found that 20.6 percent (166 of 805) of the patients had elevated serum cTnI levels (defined as cTnI >0.02 ng/mL), while 1.2 percent had documented postoperative myocardial infarction (10 of 805). Among at risk total knee arthroplasty (TKA), total hip arthroplasty (THA), or posterior spinal fusion (PSF) patients, 19 percent (102 of 532) had elevated cTnI levels and 31 percent (32 of 102) had postoperative cardiac complications. After adjustment for sex, age, body mass index, cardiac risk factors, and medications (statins and ß-blockers), the authors note that PSF patients were significantly more likely to experience myocardial injury compared to TKA and THA patients.
