The authors conclude that in patients with idiopathic dilated cardiomyopathy, the prognostic role of impaired microvascular CFR has been shown to be unfavourable. In our opinion, some points of this work are not completely clear.
First of all, it is not correct to diagnose an idiopathic dilated cardiomyopathy only upon exclusion of ischaemic heart disease after coronary angiography. Authors excluded patients with myocarditis. How can they exclude myocarditis without performing endomyocardial biopsies? Myocarditis is only diagnosed by established histopathological, histochemical, or molecular criteria on …Read More
