Viral cardiomyopathy occurs when viral infections cause myocarditis with a resulting thickening of the myocardium and dilation of the ventricles. These viruses include Coxsackie B and adenovirus, echoviruses, influenza H1N1, Epstein–Barr virus, rubella (German measles virus), varicella (chickenpox virus), mumps, measles, parvoviruses, yellow fever, dengue fever, polio, rabies, and the ...
Myocarditis can progress to inflammatory cardiomyopathy when there are associated ventricular remodeling and cardiac dysfunction due to chronic inflammation. [6] [7] Symptoms can include shortness of breath, chest pain, decreased ability to exercise, and an irregular heartbeat. [1] The duration of problems can vary from hours to months.
Viral-induced dilated cardiomyopathy can be characterized using different methods. A 2011 study showed in coxsackievirus infected heart proteome , increased levels of fibrotic extracellular matrix proteins and reduced amounts of energy-producing enzymes can be observed suggesting they could be characteristic in enteroviral cardiomyopathy.
In 2015 cardiomyopathy and myocarditis affected 2.5 million people. [6] Hypertrophic cardiomyopathy affects about 1 in 500 people while dilated cardiomyopathy affects 1 in 2,500. [3] [10] They resulted in 354,000 deaths up from 294,000 in 1990. [7] [11] Arrhythmogenic right ventricular dysplasia is more common in young people. [2]
Mortality in HIV-infected patients with cardiomyopathy is increased independently of CD4 count, age, sex, and HIV risk group. [30] [31] The therapy is similar to therapy for non-ischemic cardiomyopathy: after medical therapy is begun, serial echocardiographic studies should be performed at 4-months intervals. If function continues to worsen or ...
ICD-10 is the 10th revision of the International Classification of Diseases (ICD), a medical classification list by the World Health Organization (WHO). It contains codes for diseases, signs and symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or diseases. [1]
Before cardiac symptoms are detected, some 66% of cases have symptoms of a common cold and 33% have symptoms of asthma, rhinitis, urticarial, or other allergic disorder. Cardiac manifestations of eosinophilic myocarditis range from none to life-threatening conditions such as cardiogenic shock or sudden death due to abnormal heart rhythms .
They have been associated with gastroenteritis, influenza-like symptoms and non-polio-associated acute flaccid paralysis. The first infection of cardiovirus in humans was identified in 2007 in a stool sample of an infant that was experiencing fever of unknown origin. [ 5 ]
