In high-risk patients, the benefits from SBP lowering below 130 mmHg are driven mostly by a reduction of stroke; myocardial infarction is unaffected and cardiovascular mortality is unchanged or increased. Future trials should be designed to test the value of SBP lowering in high-risk patients with SBP in the range of 130-150 mmHg.
Perioperative AIS is an important source of morbidity and mortality associated with noncardiac, nonvascular surgery, particularly in elderly patients and patients with atrial fibrillation, valvular disease, renal disease, or previous stroke.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
