The Center for Teaching and Research Beneficence Portuguese of Sao Paulo has just completed its second phase of Revasc, further study on coronary artery bypass grafting of the country The results show that 77% of patients undergoing myocardial revascularization, also known as a bridge saphenous vein showed no cardiovascular complications after surgery.

The study involved 3010 patients, operated by 14 teams of the Institution of cardiac surgery between July 2009 and July 2010 and also shows that only 2% of patients had mediastinitis, deep infection in the wound.

Revasc shows that 700 patients had some type of cardiovascular complication in the period remained hospitalized after surgery. Of the total registered cardiovascular complications postoperatively, 14% were related to the FAA (Acute Atrial Fibrillation), a common complication after surgery. According to medical literature, the FAA is responsible for up to 50% of cases of cardiovascular complications in post-operative bypass.

The FAA increases the risk of renal failure, wound infection, stroke and myocardial infarction. The complication also increases the time that the patient is subjected to mechanical ventilation.

The FAA recorded in the percentage of patients in the study attests to the quality of care provided to patients operated by the institution and enhances the expertise of the hospital in cardiac procedures, Alexandre Sousa says cardiologist, a physician researcher at the Center for Teaching and Research of Charity of St. Portuguese Paulo.

The specialist, low levels of FAA are key to reducing the mortality rate of patients, especially those that occur in the first 30 days after the surgery.

Mediastinitis <b> </ b>

Revasc also showed that rates of mediastinitis recorded in bypass surgeries performed in Portuguese Charity of St. Paul, were below the acceptable percentage for the international scientific community. Only 64 of 3,010 patients operated in the institution had mediastinitis, deep infection in the region of the mediastinum. The percentage of mediastinitis is internationally accepted up to 3% of surgical cases. The infection has reached 2% of patients operated on Beneficence Portuguese of Sao Paulo.

Avoid mediastinitis is imported by several aspects, including, for without an infection rate of patient survival at 5 years is greater than 70%. Who already had the infection presents in the same period, survival rate of 50%, says Sousa.

The patient with mediastinitis is a time of prolonged stay in the hospital and remained hospitalized for an average of 35 days. The patient who did not have this type of infection remains hospitalized for about 16 days.

Revasc The results were presented at the 66th Brazilian Congress of Cardiology, held 16-19 September in Porto Alegre / RS.
