Trimetazidine in Myocardial Injury After Percutaneous Coronary Intervention in Patients With Angina and Diabetes
- Conditions
- Diabetes MellitusAngina, Unstable
- Interventions
- Drug: Placebo Oral Tablet
- Registration Number
- NCT03715582
- Lead Sponsor
- University of Sao Paulo General Hospital
- Brief Summary
Introduction: Recent studies have suggested that trimetazidine may help reduce myocardial damage following percutaneous coronary intervention. However, the evaluation of the potential of this medication in the reduction of myocardial damage in patients with diabetes mellitus and unstable angina, in a prospective and randomized way, has not yet been described. Objective: The aim of this study was to evaluate the efficacy and safety of the use of trimetazidine versus placebo in patients with diabetes mellitus and unstable angina undergoing coronary stent angioplasty. Methodology: For this, a unicentric, randomized, double blind and prospective study will be performed in a comparative manner. Hospital data (test results, medical outcomes, drug dose, complications) of patients will be analyzed for safety and effectiveness. Myocardial damage will be measured by means of ultrasensitive Troponin dosages. Expected results: The use of trimetazidine reduces myocardial damage in patients with diabetes mellitus and unstable angina undergoing coronary stent angioplasty.

Group Intervention Description placebo Placebo Oral Tablet The randomization will be done with a list generated by the central pharmacy of the Hospital das Clínicas, Medical School, USP. When randomized to the placebo oral tablets group, the patient will receive placebo (orally, 2 single dose tablets) also 2 hours prior to PCI. trimetazidine trimetazidine The randomization will be done with a list generated by the central pharmacy of the Hospital das Clínicas, Medical School, USP. When the patient is randomized to the trimetazidine pill group, he / she will initiate the medication at 70 mg oral dose (2 tablets of Vastarel ® MR 35 mg single dose) 2 hours before the procedure.
