People who have a normal ECG and who are able to exercise, for example, do not merit routine imaging. [13] Imaging tests such as stress radionuclide myocardial perfusion imaging or stress echocardiography can confirm a diagnosis when a person's history, physical exam, ECG and cardiac biomarkers suggest the likelihood of a problem. [13]
Eosinophilic myocarditis is often viewed as a disorder that has three progressive stages. The first stage of eosinophilic myocarditis involves acute inflammation and cardiac cell necrosis (i.e. areas of dead cells); it is dominated by symptoms characterized as the acute coronary syndrome such as angina, heart attack and/or congestive heart failure.
An electrocardiogram is one of the most common screening tools used in cases of suspected cardiac pathology, such as myocarditis. The findings that correlate with poorer outcomes are non-specific and include widened QRS complexes and QT intervals, partial or complete atrial-ventricular heart block, and malignant ventricular arrhythmias like ...

Test Sensitivity and specificity Approximate peak Description Troponin test: The most sensitive and specific test for myocardial damage. Because it has increased specificity compared with CK-MB, troponin is composed of 3 proteins- Troponin C, Cardic troponin I, and Cardiac troponin T. Troponin I especially has a high affinity for myocardial injury.
Dilated Cardiomyopathy Echocardiogram In addition to the patient's medical history and physical exam, the diagnosis of alcoholic cardiomyopathy is often confirmed with various diagnostic tests. [ 8 ] One of the most common tests is an echocardiogram, which uses ultrasound waves to create images of the heart and can detect abnormalities in the ...
Age dependent normal values for S', e' and a'. The e'/a' ratio becomes <1 about 60 years of age, which is similar to the E/A ratio of mitral flow. Women has slightly higher S' and e' velocities than men, although the difference disappears with age.
Cardiomyopathy is a group of primary diseases of the heart muscle. [1] Early on there may be few or no symptoms. [1] As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. [1]
