Dilated cardiomyopathy (DCM) is a relatively rare primary heart muscle disease with genetic or post-inflammatory etiology. In the last decade, the incidence and prevalence of the disease have significantly increased as a consequence of an earlier diagnosis supported by extensive familial screening programs and by the improvement in diagnostic techniques. Moreover, current therapeutic strategies have deeply modified the prognosis of DCM with a dramatic reduction in mortality. A significant number of patients with DCM present an impressive response to pharmacological and non-pharmacological therapy in terms of left ventricular reverse remodeling (reduction in ventricular size with improvement of systolic function), which confers a more favorable prognosis in the long term. However, the identification of patients with an increased likelihood of improvement after therapeutic optimization remains a challenging issue; in particular the assessment of arrhythmic risk carries important implications. Finally, the long-term follow-up of patients showing a significant left ventricular functional recovery under optimal treatment is still poorly known. Hence, the aim of the present review is to provide an insight into the clinical evolution/long-term follow-up of DCM, which should be actually considered a dynamic process rather than a static and chronic disease. Left ventricular reverse remodeling should be considered a key therapeutic goal, mostly associated with a long-standing recovery, but cannot be considered the expression of permanent "healing", confirming the need for a systematic and careful follow-up over time in this setting.

Abstract

Dilated cardiomyopathy (DCM) is a relatively rare primary heart muscle disease with genetic or post-inflammatory etiology. In the last decade, the incidence and prevalence of the disease have significantly increased as a consequence of an earlier diagnosis supported by extensive familial screening programs and by the improvement in diagnostic techniques. Moreover, current therapeutic strategies have deeply modified the prognosis of DCM with a dramatic reduction in mortality. A significant number of patients with DCM present an impressive response to pharmacological and non-pharmacological therapy in terms of left ventricular reverse remodeling (reduction in ventricular size with improvement of systolic function), which confers a more favorable prognosis in the long term. However, the identification of patients with an increased likelihood of improvement after therapeutic optimization remains a challenging issue; in particular the assessment of arrhythmic risk carries important implications. Finally, the long-term follow-up of patients showing a significant left ventricular functional recovery under optimal treatment is still poorly known. Hence, the aim of the present review is to provide an insight into the clinical evolution/long-term follow-up of DCM, which should be actually considered a dynamic process rather than a static and chronic disease. Left ventricular reverse remodeling should be considered a key therapeutic goal, mostly associated with a long-standing recovery, but cannot be considered the expression of permanent "healing", confirming the need for a systematic and careful follow-up over time in this setting.
