Filter by:The goal of this study is to address specific implementation questions necessary and sufficient to ensure the feasibility of the larger randomized trial examining the efficacy of statin medications in slowing rheumatic heart disease (RHD) valvular pathology progression. This feasibility study is intended to confirm the number of readily recruitable subjects, assess recruitment rate, and assess the rate of valve pathology via echocardiograms. These results are necessary and sufficient to facilitate the successful design of a large full scale randomized trial to determine whether statins improve outcomes in RHD. Successful treatment of RHD would fundamentally shift the RHD management paradigm world-wide, improve the lives of millions afflicted with RHD, and subsequently, decrease health care spending on RHD management.
Objective: The purpose of the present study is to assess if perioperative variation of Brain Natriuretic Peptide (BNP) levels is a predictor of mortality and morbidity after cardiac surgery.Material and Methods: 500 consecutive patients will be enrolled prospectively in this study before cardiac surgery under cardiopulmonary bypass. BNP levels will be measured prior to surgery and at postoperative day 1. Variations of BNP levels will be analyzed to determine if it is a predictor of mortality and morbidity after cardiac surgery. This dynamic evaluation will be compared to other tools of risk stratification in cardiac surgery as the EuroScore. All patients will be followed 3 years after the procedure. Hypothesis: Perioperative BNP variations may be more sensitive than pre- or postoperative BNP levels alone. Furthermore the perioperative homeostasis will be measured to assess its impact on BNP secretion during the perioperative period.
