Abstract 11787: Derivation and Validation of a Score System to Stratify Post-op Valvular Patients in Cardiac Rehab

BackgroundThe importance of Cardiovascular Rehabilitation (CR) in post-surgical valvular patients both for the functional recovery and the monitoring of complications is well-known. However, indicators to better categorize their risk and to identify the real probability of recovery are not available.PurposeThe aim of this study is to define and validate a scoring system to stratify post-surgical valvular patients in order to appropriately individualize CR programs.MethodsA retrospective study was conducted on 1480 consecutive post-surgical valvular patients hospitalized in our CR Unit (902 M; median age 64 years)485 underwent single valve repair, 408 single valve replacement, 237 single valve surgery and additional interventions, 249 multiple valve interventions and 101 multiple valves and additional interventions. For data analysis subjects were randomized in a Derivation (D; n = 1000) and a Validation (V; n = 480) Group. In Group D the predictive value of anamnestic, clinical and laboratory variables for major complications and functional recovery was assessed. Two scoring systems for the outcomes were created and validated on Group V. Finally, we interlaced them in an operative algorithm.ResultsChronic kidney disease (OR 2.588; p=0.012), sternal surgical re-synthesis (OR 7.757; p=0.003), post-surgical transfusions (OR 2.419; p=0.001) and troponin T peak > 1400 μg/L (OR 2.441; p=0.001) were independent predictors for the occurrence of major complications in Group D and age (OR 0.958; p
