Beta-Blocker Therapy in Noncardiac Surgery
Perioperative myocardial infarction is a major cause of complications and death among patients undergoing noncardiac surgery. 1 Annually in the United States, approximately 27 million patients are given anesthesia for surgical procedures; of these, approximately 50,000 patients have a perioperative myocardial infarction. 2 The pathophysiology of an acute perioperative myocardial infarction is p...

متن کاملProarrhythmic versus antiarrhythmic mechanisms of cardiac resynchronization therapy
Cardiac resynchronization therapy (CRT) has recently become an established therapy for patients with NYHA class III/IV systolic heart failure and prolonged QRS duration [1]. In addition to improvement in exercise capacity, NYHA symptoms class, and quality of life, evidence of the arrest or reversal of ventricular remodeling has been demonstrated [2]. A recent meta-analysis found that CRT reduce...
متن کاملPredicting the effectiveness of beta-blocker therapy in vasovagal syncope.
There has been a great deal of interest in the therapeutic role of beta-adrenergic blockade in patients suffering from vasovagal syncope. The efficacy of beta-blockers in these patients may be due to blunting of elevated catecholamine levels that precede vasovagal syncope (1). Notwithstanding the widespread use of beta-blockers in the past, some studies on chronic beta-blocker use have been les...
متن کاملBeta-blocker therapy for secondary prevention of myocardial infarction.
Beta-blockers are effective agents for secondary prevention post-myocardial infarction (MI). They have antiarrhythmic, anti-ischemic, and antihypertensive effects that decrease morbidity and mortality in patients after an MI. Critical care nurses can play an active role in recognizing those patients, especially high-risk individuals, who may benefit from beta-blocker therapy.
