Prehospital HMG Co-A reductase inhibitor use and reduced mortality in ruptured abdominal aortic aneurysm



Prehospital HMG Co-A reductase inhibitor use and reduced mortality in ruptured abdominal aortic aneurysm



Journal of the American College of Surgeons 209(1): 41-46



The compounds 3-hydroxy-3-methyl-glutaryl-CoA reductase inhibitors (HMG Co-A reductase inhibitors, statins) are popular medications for the control of elevated serum cholesterol. Recent evidence has demonstrated a survival benefit to patients who take statins in the premorbid period with severe sepsis, septic shock, or severe trauma. We hypothesized that a similar benefit would be seen in patients with ruptured abdominal aortic aneurysm. We completed a retrospective review of patients with ruptured abdominal aortic aneurysm in our institution from January 2000 to December 2008. We compared age, gender, mortality rates, and Physiologic and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) scores for all patients who met inclusion and exclusion criteria. We compared hospital and ICU lengths of stay, cardiac morbidity, and number of cardiac events per patient between survivor groups with and without prehospital statin use. We compared mortality, cardiac morbidity, and gender using the Pearson chi-square test, Physiologic and Operative Severity Score for the enumeration of Mortality and Morbidity scores and age using the Student's t-test and lengths of stay using the Mann Whitney-U test. Mortality in the group without prehospital statin use was 63.8%, and in the group with prehospital statin use was 34.8% (p=0.018, odds ratio 0.30 to 0.11). Physiologic and Operative Severity Score for the enumeration of Mortality and Morbidity scores were similar between survivor groups with and without statin use and nonsurvivor groups with and without statin use. Hospital and ICU lengths of stay, cardiac morbidity, and number of cardiac events per patient were not statistically different among survivors. Prehospital statin use appears to be associated with a significant survival benefit in the ruptured abdominal aortic aneurysm population.
