Direct current cardioversion does not cause cardiac damage: evidence from cardiac troponin T estimation

Direct current cardioversion does not cause cardiac damage: evidence from cardiac troponin T estimation.

AIM To determine whether elective direct current (dc) cardioversion of atrial fibrillation/flutter causes myocardial damage. METHODS AND RESULTS Cardiac troponin T and creatine kinase were estimated 20-28 hours after dc cardioversion in 51 patients who received dc shocks for elective cardioversion of chronic atrial fibrillation/flutter. Although creatine kinase was raised in 44 patients, card...

Cardiac troponin T does not increase after electrical cardioversion for atrial fibrillation or atrial flutter.

OBJECTIVE To determine whether cardiac troponin T increases after electrical cardioversion in patients with atrial fibrillation or atrial flutter. DESIGN Serum creatine kinase (CK), creatine kinase-MB (CKMB), and cardiac troponin T were measured before, 24 hours, and 48 hours after cardioversion in 15 patients with atrial fibrillation or atrial flutter. RESULTS 12 of the 15 patients (80%) w...

Cardiac Troponin I but Not Cardiac Troponin T Induces Severe Autoimmune Inflammation in the Myocardium

Background—Cardiac troponins in blood are the most preferred markers of myocardial damage. The fact that they are normally not found in the circulation provides a high level of clinical sensitivity and specificity even when cardiac lesions are small. After myocardial injury, the troponins enter the circulation, where they can be used for diagnosis of acute coronary syndromes. Thus, the cardiac ...

Troponin T elevation in amyotrophic lateral sclerosis without cardiac damage.

Cardiac troponin I, cardiac troponin T, and creatine kinase MB in dialysis patients without ischemic heart disease: evidence of cardiac troponin T expression in skeletal muscle.

Serum cardiac troponin T (cTnT) concentrations are frequently increased in chronic dialysis patients as measured by the first-generation ELISA immunoassay, as is creatine kinase (CK) MB mass in the absence of acute ischemic heart disease. We designed this study to compare four serum markers of myocardial injury [CK-MB mass, first-generation ELISA cTnT, second-generation Enzymun cTnT, and cardia...
