This is descriptive study aims to determine prevalence and outcome of patients with end stage cardiomyopathies in the pediatric cardiac intensive care unit subjected to various inotropic support therapies in Cairo University Specialized Children Hospital over six months from 1/6/2010 to 31/12/2010. During the duration of the study there was 20 cases admitted to PCICU diagnosed as dilated cardiomyopathy one of them non compaction type from 122 cases who were admitted in the same period with cardiac problems with prevalence 16.3% during 6 month of study. While only one case admitted diagnosed as hypertrophic cardiomyopathy with prevalence less than 1%. There were no cases admitted of restrictive cardiomyopathy. DCM patients’ outcome in our study showed that left ventricular end diastolic diameter, severity of mitral regurge and duration of stay in PCICU to be significant in prediction of outcome of cases while age, sex, fractional shortening, mural thrombus, electrolyte disturbance, different inotropic support and arrhythmias did not predict or affect the outcome of cases.SO we recommend thatmore elaborated studies should be conducted on a larger number of cardiomyopathic patients to establish the true significance factors that can be used as predictorsof outcome of management of these cases of cardiomyopathy.
