**Classification of primary cardiomyopathies:**


European Society of Cardiology in 2008 introduced a classification in which they accommodated five specific types of cardiomyopathies along with their genetic involvement: dilated, hypertrophic, arrhythmogenic, restrictive, and unclassified [2]. They further divided them

Chemotherapy drugs: doxorubicin, daunorubicin, cyclophosphamide

The most recent classification known as the MOGE(S) classification system had been introduced which is based on phenotype and genotype an it incorporates information on structural and functional abnormalities (M), organ involvement (O), genetics (G), aetiology (E), and disease severity (S) associated with the condition [3]. However, it cannot be considered as complete as it does not include certain cardiomyopathies like postpartum cardiomyopathy or the risk of sudden death and is very complex to use. The MOGES classification is beyond the

Cardiomyopathy itself can present as either systolic dysfunction or diastolic dysfunction,
