The original 2009 Lake Louise Criteria had a 74% sensitivity and 86% specificity in the diagnosis of myocarditis, but when adding the 2018 update to the criteria (in which T1 signal intensity was found to have high diagnostic sensitivity), the sensitivity and specificity in the diagnosis of myocarditis increased to 88% and 96% respectively.
Median age from the time the disease is diagnosed to the time of death is approximately 6 months. 90% of patients are either deceased by the end of 1 year or have received a heart transplant. Diagnosis is made by endomyocardial biopsy during heart catheterization. Biopsy shows multinucleated giant cells and thus the name. While previously cases ...
Mortality is between 40–80% 10 years post-diagnosis. [9] The prognosis of alcoholic cardiomyopathy (ACM) varies depending on the severity of the condition, the extent of heart muscle damage, and the response to treatment. Without treatment, ACM can progress to severe heart failure, arrhythmias, and sudden cardiac death. [10]
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 ...
The alphanumeric coding in ICD-10 is an improvement from ICD-9 which had a limited number of codes and a restrictive structure. [49] Early concerns in the implementation of ICD-10 included the cost and the availability of resources for training healthcare workers and professional coders. [60]
Myocarditis has been documented at autopsy in 40–52% of patients who died of AIDS before the introduction of HAART. [10] Toxoplasma gondii is the most common opportunistic infectious agent associated with myocarditis in AIDS occurring in 12% of deaths from AIDS 1987-1991 in one autopsy series. [ 11 ]
Gadolinium-based cardiac magnetic resonance imaging is the most useful non-invasive procedure for diagnosing eosinophilic myocarditis. It supports this diagnosis if it shows at least two of the following abnormalities: a) an increased signal in T2-weighted images; b) an increased global myocardial early enhancement ratio between myocardial and ...
ICD versions before ICD-9 are not in use anywhere. [16] ICD-9 was published in 1977, and superseded by ICD-10 in 1994. The last version of ICD-10 was published in 2019, and it was replaced by ICD-11 on 1 January 2022. [17] As of February 2022, 35 of the 194 member states have made the transition to the latest version of the ICD. [18]
