Conclusions Examination of 883 cases of AAA repair showed increased mortality associated
with preoperative RAS blockade. A better understanding of perioperative pharmacology and …

There are no existing guidelines supporting the withdrawal or continuation of renin–
angiotensin–aldosterone system (RAAS) antagonists in the preoperative setting. RAAS …

Background Acute kidney injury (AKI) is a common complication after cardiovascular
surgery. The use of renin angiotensin system (RAS) blockers preoperatively is controversial …

Major complications associated with cardiac surgery are still common and carry great
prognostic significance. β-Blockers, statins, antiplatelets, and renin-angiotensin system …

Both ACE inhibitors and ARBs act on the RAP to cause arterial vasodilation by 2 separate
mechanisms: limiting the direct effects of angiotensin II on vascular smooth muscle, and by …

Renin angiotensin system (RAS) antagonists, angiotensin-converting enzyme (ACE)
inhibitors, and angiotensin II receptor antagonists are increasingly used to treat …

A NGIOTENSIN-converting enzyme (ACE) inhibitors are increasingly used in the treatment
of cardiovascular diseases.'-3 The number of patients chronically treated with ACE inhibitors …

Objective The effects of preoperative (pre-op) renin-angiotensin system (RAS) inhibitors on
outcomes in patients undergoing cardiac surgery remain uncertain. The aim of this study …

Objective The objective of this study was to summarize the literature regarding the effects of
renin-angiotensin system blockade (RASB) using angiotensin-converting enzyme inhibitors …

Postoperative renal impairment can increase postoperative mortality and morbidity. We
sought to identify preoperative risk factors responsible for postoperative renal impairment in …
