Myocarditis and inflammatory cardiomyopathy: microbiological and molecular biological aspects. 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.

Most patients with chronic pancreatitis have had one or more attacks of acute pancreatitis resulting in inammatory change and brosis, but some patients have a more insidious onset. In 2013, the European Society of Cardiology (ESC) pointed out misunderstandings and confusion regarding the terminology and concepts of myocarditis, inflammatory cardiomyopathy and recommended the definitions as follows: Dilated cardiomyopathy is a clinical diagnosis based on morphological and functional characterization of the left ventricle; inflammatory cardiomyopathy is … Cardiomyopathies. Reversible toxic myocarditis occurs in diphtheria and sometimes in infective endocarditis when autoimmune mechanisms may also … Viral infection is a possible trigger of immune and autoimmune mechanisms which contributed to the damage of myocardial function. Affiliations. The catastrophic results of a damaged myocardium include congestive heart failure, cardiogenic shock, and sudden arrhythmogenic death. Circulation. Viral myocarditis is becoming increasingly recognised as a contributor to under … Many distinct cardiac autoantibodies e.g. The pathohistological criteria at that time were the Dallas criteria [ 7 ], which distinguished active, recurrent, healing and borderline myocarditis (Tab. Clinical presentation of the disease is highly variable, ranging from nonspecific flu-like symptoms, arrhythmias, palpitations, dizziness, and syncope, to left ventricular failure.
