After ruling out acquired disorders such as IHD, RHD, VHD, and CHD, the clinician could identify the cardiomyopathy based on the findings of a non-invasive echocardiogram, such as N-terminal pro-B-type natriuretic peptide (BNP) levels with LV end-diastolic maximum wall thickness (51). This evidence concerns the gene NPPB and myocardial ischemia.
