Risk factors for in-patient myocardial infarction following total hip arthroplasty. | LitMetric

AI Article Synopsis

  • The study aimed to identify risk factors for myocardial infarction (MI) occurring immediately after total hip arthroplasty (THA) using a large patient database from 2016 to 2019.
  • An analysis of 367,890 THA patients revealed that those who experienced an MI tended to be older, female, and more likely to have certain health conditions like obesity and Parkinson's disease, while elective admissions reduced the risk.
  • The findings suggest that understanding these risk factors can help healthcare providers implement better precautions and treatment strategies for patients undergoing THA.

Article Abstract

Purpose: The aim of this study was to identify potential risk factors for myocardial infarction immediately following total hip arthroplasty.

Methods: The 2016-2019 Nationwide Inpatient Sample database was used to identify patients who underwent primary total hip arthroplasty (THA) and suffered a myocardial infarction (MI). Patient data including demographics, admission, and comorbidities were recorded. Univariate analysis and subsequent multivariate logistic regression were performed to determine which circumstances affected the odds of MI.

Results: A total of 367,890 patients were identified for THA with 142 of those also having a myocardial infarction. Those who experienced an MI had increased length of stay, total charges, and generally negative dispositions compared to their non-MI counterparts ( < 0.001). Through regression analysis, factors that increased the odds of MI included older age [odds ratio (OR) 1.59, 95 % confidence interval (CI) 1.49-1.70], a female sex (OR 1.46, 95 % CI 1.37-1.55), previous coronary artery bypass graft (OR 1.20, 95 % CI 1.01-1.43), obesity (OR 1.12, 95 % CI 1.04-1.21), colostomy (OR 2.07, 95 % CI 1.21-3.56), and Parkinson's disease (OR 1.48, 95 % CI 1.13-1.95). Factors that decreased that risk included elective admission (OR 0.21, 95 % CI 0.19-0.22) and a tobacco related disorder (OR 0.69, 95 % CI 0.63-0.76).

Conclusions: Patient risk for myocardial infarction following total hip arthroplasty varies in part based on their background and comorbidities. These findings can be used to better recognize those who should receive further precautions and tailor proper treatment strategies for THA.
