Randomized Controlled Trial Multicenter Study Clinical Trial
Short-term intravenous milrinone for acute exacerbation of chronic heart failure: a randomized controlled trial.
Little randomized evidence is available to guide the in-hospital management of patients with an acute exacerbation of chronic heart failure. Although intravenous inotropic therapy usually produces beneficial hemodynamic effects and is labeled for use in the care of such patients, the effect of such therapy on intermediate-term clinical outcomes is uncertain. ⋯ These results do not support the routine use of intravenous milrinone as an adjunct to standard therapy in the treatment of patients hospitalized for an exacerbation of chronic heart failure.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Intravenous nesiritide vs nitroglycerin for treatment of decompensated congestive heart failure: a randomized controlled trial.
Decompensated congestive heart failure (CHF) is the leading hospital discharge diagnosis in patients older than 65 years. ⋯ When added to standard care in patients hospitalized with acutely decompensated CHF, nesiritide improves hemodynamic function and some self-reported symptoms more effectively than intravenous nitroglycerin or placebo.

Randomized Controlled Trial Comparative Study Clinical Trial
Cognitive outcome after off-pump and on-pump coronary artery bypass graft surgery: a randomized trial.
Coronary artery bypass graft (CABG) surgery is associated with a decline in cognitive function, which has largely been attributed to the use of cardiopulmonary bypass (on-pump procedures). Cardiac stabilizers facilitate CABG surgery without use of cardiopulmonary bypass (off-pump procedures) and should reduce the cognitive decline associated with on-pump procedures. ⋯ Patients who received their first CABG surgery without cardiopulmonary bypass had improved cognitive outcomes 3 months after the procedure, but the effects were limited and became negligible at 12 months.

Recent studies suggest that perioperatively administered beta-blockers may reduce the risk of adverse cardiac events in patients undergoing major noncardiac surgery. ⋯ Despite heterogeneity of trials, a growing literature suggests a benefit of beta-blockade in preventing perioperative cardiac morbidity. Evidence from these trials can be used to formulate an effective clinical approach while definitive trials are awaited.
