Medical Research: What is the background for this study? What are the main findings?

Dr. Sanders: While it is known that chronic raised blood pressure exerts important effects on long term health outcomes, it is unclear how pre-operative blood pressure levels effect risk from surgery. In this study we show that after adjustment for other diseases, high blood pressure does not increase perioperative risk. Rather low blood pressure is associated with an increase in risk of death following surgery and anesthesia.

Medical Research: What should clinicians and patients take away from your report?

Dr. Sanders: Based on our study, clinicians and patients should be aware that having low blood pressure is associated with increased risk of death following surgery. Future research must focus on the mechanisms through which low blood pressure before the operation may lead to increased risk.
