OBJECTIVE: This study was designed to investigate whether patients with stable
coronary artery disease (CAD) receiving chronic statin treatment who are
undergoing noncardiac emergency surgery benefit from acute atorvastatin reload.
METHODS: A total of 500 patients with stable CAD and regular administration of
statin before noncardiac emergency surgery were randomized to atorvastatin reload
(n = 250) or placebo (n = 250). All patients received atorvastatin treatment
thereafter. The primary end point was a 30-day incidence of major adverse cardiac
events (MACE). Secondary end points were the incidence of atrial fibrillation
(AF) during hospitalization and length of hospital stay.
RESULTS: The primary end point occurred in 2.4% of patients treated with
atorvastatin reload and in 8% in the placebo arm (p = 0.0088). The incidence of
AF during hospitalization was 6.8% in patients treated with atorvastatin reload
and 17% in the placebo arm (p = 0.0003). Compared with the placebo arm, the
atorvastatin reload arm shortened the length of stay (9.8 ± 3.3 vs. 10.6 ± 3.5
days, p = 0.009). Multivariable analysis suggested that atorvastatin reload
conferred a 65% risk reduction of 30-day MACE (odds ratio 0.35, 95% confidence
interval 0.18-0.86; p = 0.005).
CONCLUSION: The trial suggests that atorvastatin reload may improve the clinical
outcome of patients with stable CAD receiving chronic statin treatment who are
undergoing noncardiac emergency surgery.
