Randomized Controlled Trial Multicenter Study Comparative Study
Influence of diabetes mellitus on inappropriate and appropriate implantable cardioverter-defibrillator therapy and mortality in the Multicenter Automatic Defibrillator Implantation Trial-Reduce Inappropriate Therapy (MADIT-RIT) Trial.
The relationship between diabetes mellitus and risk of inappropriate or appropriate therapy in patients receiving an implantable cardioverter-defibrillator (ICD) and resynchronization therapy has not been investigated thoroughly. The effect of innovative ICD programming on therapy delivery in these patients is unknown. ⋯ URL: http://www.clinicaltrials.gov. UNIQUE IDENTIFIER: NCT00947310.

Young adults born preterm have distinct differences in left ventricular mass, function, and geometry. Animal studies suggest that cardiomyocyte changes are evident in both ventricles after preterm birth; therefore, we investigated whether these young adults also have differences in their right ventricular structure and function. ⋯ Preterm birth is associated with global myocardial structural and functional differences in adult life, including smaller right ventricular size and greater mass. The changes are greater in the right ventricle than previously observed in the left ventricle, with potentially clinically significant impairment in right ventricular systolic function.
