Cardiac biomarker release after CABG with different surgical techniques.
To investigate the release of cardiac biomarkers (troponin I and CK-MB) in patients undergoing coronary artery bypass graft (CABG) with or without cardiopulmonary bypass (CPB). ⋯ Cardiac troponin I release after multivessel CABG is associated with the technique. Different values for the normal range should be considered. OPCABG is minimally invasive for the heart as far as myocardial marker release is concerned.

Comparative StudyECG changes after CABG: the role of the surgical technique.
The purpose of this study was to determine whether coronary artery bypass grafting (CABG) surgery on the beating heart (BH) is associated with reduction of R-wave potentials on the precordial leads on the surface electrocardiogram (ECG) as previously shown for CABG with cardiopulmonary bypass. ⋯ The findings indicate, for the first time, that CABG surgery on the BH is not followed by any reduction of R-wave amplitude on precordial leads and confirms that the BH technique is associated with a lower release of myocardial cell damage markers.

Comparative StudyCardiac output monitoring during off-pump coronary artery bypass grafting.
To evaluate and compare monitors of cardiac output during repositioning and stabilization of the heart for off-pump coronary artery bypass (OPCAB) surgery. ⋯ The use of the VTI*HR, as determined by TEE, in addition to the SvO(2) can strengthen clinical decision making during repositioning and stabilization of the heart during OPCAB. Changes in the VTI*HR and SvO(2) can be used as surrogate markers for changes in CO during OPCAB surgery.

Comparative StudyPerioperative changes in atrial natriuretic peptide plasma levels associated with mitral and aortic valve replacement.
Atrial natriuretic peptide (ANP) plasma levels are increased in patients with valvular heart disease. The present study investigates possible changes after mitral or aortic valve replacement (MVR, AVR). ⋯ ANP levels are not altered during and 1 week after valve replacement and, therefore, do not reflect hemodynamic changes perioperatively.

Comparative StudyCost-effectiveness of differing perioperative beta-blockade strategies in vascular surgery patients.
To determine the incremental value of different strategies of both oral and intravenous beta-blockade during the perioperative period in high-risk vascular patients in reducing costs and improving outcomes. ⋯ Perioperative beta-blockade is both cost effective as well as efficacious from a short-term provider perspective. The optimal strategy of treatment for patients who do not present to surgery already on beta-blockers requires further study, although all strategies save money even accounting for pharmaceutical costs.
