Statin use is associated with less postoperative cardiac arrhythmia after total hip arthroplasty.
This study investigated if statins would similarly reduce postoperative arrhythmias in patients undergoing THA.
METHODS:: We queried a large Medicare and private-payer database from 2005 to 2012 and identified 12,075 patients who were on a statin prior to THA. We then age and sex matched 34,446 non-statin users who underwent THA. Baseline comorbidities and postoperative complications were obtained and assessed via standard descriptive statistics.
RESULTS:: The statin users had more preoperative comorbidities including congestive heart failure, valvular heart disease, pulmonary and renal disease, diabetes, hypertension, obesity, and anaemia (all p values < 0.001). Postoperatively, the statin users had a statistically higher 90-day incidence of transfusion, acute renal failure, heart failure, pneumonia, and sepsis/shock. All new-onset cardiac arrhythmia was significantly less frequent in the statin group at 2 weeks (3.88% vs. 4.72%, p < 0.001), 30 days (4.47% vs. 5.29%, p < 0.001), and 90 days (5.44% vs. 6.31%, p = 0.001) postoperative. There was no difference in the frequency of venous thromboembolism, myocardial infarction, postoperative anaemia, or bleeding at 90 days postoperative.
DISCUSSION:: Despite being medically sicker at baseline with multiple risk factors for atrial fibrillation compared to the non-statin users, the statin users displayed a consistently lower occurrence of postoperative cardiac arrhythmia in this retrospectiv...
