Methods and results Between 2007 and 2011 all consecutive patients with diagnosed with iCM at EMB were retrospectively analyzed. The combined primary endpoint （EP） （1E°P） was cardiac death, aborted sudden cardiac death/appropriate implantable cardioverter defibrillator （ICD） shock, progressive heart failure requiring left venWicular assist device （LVAD） implantation and heart transplantation. 503 patients （mean age 58 ° 12 years, 73% male） were available for analysis. Genomes of cardiotrophic viruses were detected in 396 patients （79%） and immuno-histochemical signs of inflammation were present in 223 individuals （44%）. After 3.6 ° 2.4 years of follow-up, cardiac mortality was 3.0% （n = 14） and a total of 8.6% （n = 40） reached the primary endpoint. Independent predictors for the 1 °EP were： age 〉 50 years, presence and duration （〈 28 days） of symptomatic heart failure. A risk stratification approach based on the results of the multivariate analysis demonstrated that absence of signs and/or symptoms of congestive heart failure in younger （〈 50 years） patients with longer （〉 28 days） duration of disease appear to have an excellent prognosis with 100% survival and no events during follow-up The presence of all above mentioned independent risk factors results in an 1°EP occurrence of 35.9%. Conclusions Symptoms of heart fail- ure, short duration of disease, and older age are indicators of poor outcome in patients with iCM.展开更多
