In contrast, chronic inflammatory cardiomyopathy indicates myocardial inflammation with established dilated cardiomyopathy or hypokinetic nondilated phenotype, which in the advanced stages evolves into fibrosis without detectable inflammation. Other etiologic agents responsible for myocarditis include drugs, toxic substances, or autoimmune conditions. Desmoplakin (DSP) mutations cause a unique form of cardiomyopathy with a high prevalence of LV inflammation, fibrosis, and systolic dysfunction, and DSP cardiomyopathy should be considered in the differential diagnosis for myocarditis and sarcoidosis.The presence of any LV systolic dysfunction in DSP cardiomyopathy, particularly when associated with ventricular ectopy … Myocarditis, also known as inflammatory cardiomyopathy, is inflammation of the heart muscle.

Journal of the american college of cardiology vol. Although inflammation in myocardial disease can resolve spontaneously, often specific treatment directed against the causative agent is required. It’s helpful to think of myocarditis as a disease happening in three distinct stages: Phase 1: Initial heart injury (days 0 to 3) Phase 2: Autoimmune response caused by the initial injury (days 4 to 14) Phase 3: Dilated cardiomyopathy; The link between myocarditis and DCM lies in the inflammatory response.

Cytokine mRNA (IL-1ß, TNF-ꍜ, IFN-ꍞ, IL-2) are produced and persisted as long as 80 days after inoculation: Beneficial VS Deleterious Effects 3. Inflammatory cardiomyopathy is defined as inflammation of the heart muscle associated with impaired function of the myocardium. Congestive heart failure remains one of the most prevalent and costly health problems in the United States. Myocarditis is an infectious–inflammatory disease often superimposed to individual genetic background which could favour or inhibit its progression into a chronic heart muscle disorder (most often dilated cardiomyopathy (DCM), rarely arrhythmogenic, or right-sided cardiomyopathy). Circulation. The usefulness of viral serologies is limited, especially in chronic myocarditis or inflammatory cardiomyopathy, as IgG antibodies for cardiotropic viruses can be found in the blood stream of the general population without accompanying cardiac involvement.
