About this trial
Statins have been used to low cholesterol to prevent and treat coronary artery diseases. It was also reported that statins could protect endothelial function and cardiac function during coronary artery bypass graft. The investigators recent found simvastatin reduced myocardial injury during noncoronary artery cardiac surgery in single medical center. The investigators further investigate that whether simvastatin can protect myocardium during noncoronary artery cardiac surgery with cardiopulmonary bypass and improve cardiac function with long term use postoperatively in two medical centers.

Treatments tested in this trial

Treatment groups
Trial outcomes
Primary outcomes
troponin
The investigator will measure the plasma troponin level in several time points before and after surgery in each patient. This is mainly for the comparason between control and short statin, which has been proved in our previous clinical trial: statin1.
ejection fraction
Each patient will be followed up and checked with B ultrasound on heart in 1,3,6,12,18 and 24 months after surgery. The ejection fraction will be measured. This is mainly for the comparason between short statin and long statin, which is the major goal in this clinical trial: statin 2.
Secondary outcomes
long term survival
Each patient will be followed up and observed survival time.
