Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Administration of cyclosporine has been found to have a myocardial protective effect, improving post-operative cardiac function in patients undergoing percutaneous coronary interventions by diminishing infarct size. The purpose of the proposed study is to conduct a randomized, controlled clinical trial in patients undergoing isolated valvular heart surgery, or coronary artery bypass surgery. Specifically the investigators will evaluate the cardio-protective effects of cyclosporine on post ischemic-arrest myocardium. The two factors will be treatment group and cyclosporine versus placebo.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The specific aim of this study is to perform a randomized controlled study to compare the effects of cyclosporine v. placebo on changes in myocardial functioning associated with open heart surgery for isolated valvular or coronary artery bypass procedures.

The research question is:

Compared to placebo, does administration of cyclosporine just before surgery improve myocardial functioning in terms of:

* Transthoracic ECHO (TTE) assessment of ejection fraction
* Cardiac index (CI), mixed venous oxygen saturation (SVO2), systemic vascular resistance (SVR)
* Length of stay
* 30-d mortality
* Angina Scale
* SF-36 measure of quality of life
* Measures associated with myocardial function:

1. Cardiac Index
2. Blood glucose level
3. Serum Troponin I level
4. Free Fatty Acid levels
5. Serum CPK-MB levels
6. Serum phosphoratase levels

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cyclosporine

Cyclosporine Group: Patients will receive a dose of cyclosporine just after they are heparinized. They will receive 2.5 mg of cyclosporine (Sandimmune, Novartis) per kilogram of body weight. It will be injected into a central venous line at the time the central venous line is inserted by the anesthesia team.

Intervention Type DRUG

Cyclosporine Patients will receive a dose of cyclosporine just after they are heparinized. They will receive 2.5 mg of cyclosporine (Sandimmune, Novartis) per kilogram of body weight. It will be injected into a central venous line at the time the central venous line is inserted by the anesthesia team.

Placebo

Placebo: Patients will undergo the cardiac surgery procedures using standard technique. They will have ischemic arrest of the heart with cold blood cardioplegia using standardized methods of myocardial protection or off-pump CABG. The patients in the placebo group will receive a volumetrically equivalent dose of normal saline to the cyclosporine dose.
