IMPORTANCE: Recent publications report that perioperative initiation of statin therapy is associated with improved outcomes particularly among patients with increased cardiac risk. However, findings on associations with beta blocker (BB) initiation are mixed.
OBJECTIVE: This study examines associations between perioperative statin and BB use in a national sample of patients with cardiac stents.
DESIGN: Retrospective cohort study.
SETTING: VA Medical Centers nationwide.
PARTICIPANTS: We identified Veterans Affairs (VA) patients undergoing non-cardiac surgery in the within two years after stent placement between October 2002 and September 2011 with BB and/or statin prescriptions within one year prior to surgery. Using VA inpatient data we identified major adverse cardiac or cerebrovascular events (MACCE) within 30 days of surgery. General usage patterns and percent of days covered by medication were calculated as additional markers of medication use. Adjusted logistic regression was used to examine associations between medication use and 30-day postoperative outcomes.
RESULTS: 23,537 patients underwent surgery within 2 years following stent placement, of whom 20,566 (88.6%) had prescriptions for beta blockers and statins within 365 days prior to surgery. Of those, 13,501 (65.6%) used both BB and statins prior to surgery, while 2626 (12.8%) used only BB, 2346 (11.4%) used only statins, and 2093 (10.2%) used neither. In fully adjusted models, the only significant association was between perioperative statin use and decreased mortality (OR 0.65, 95% CI 0.48-0.87).
CONCLUSIONS: Our results suggest that maintaining statin therapy perioperatively is associated with reduced 30 day mortality in stented patients undergoing non-cardiac surgery who have previously been prescribed both beta blockers and statins.
