T2 abnormalities in patients with hypertrophic cardiomyopathy characterized by cardiovascular magnetic resonance imaging- an indicator of myocardial injury as assessed by the high sensitive cardiac troponin T assay
نویسندگان
چکیده
To test the hypothesis that myocardial hyperintensities on T2 weighted imaging in patients with hypertrophic cardiomyopathy (HCM) reflect ongoing myocardial injury, the cardiacspecific biomarker troponin T was measured by a new highly sensitive assay (hs-cTnT). In 52 patients with HCM, the presence and extent of myocardial T2 abnormalities were associated with hs-cTnT levels. The number of LV segments with T2 hyper-intesity was the strongest independent predictor of hs-cTnT levels. This novel finding suggests that T2 imaging may aid in the identification of HCM patients with active and potentially progressive disease.

High signal intensity on T2 weighted cardiac magnetic resonance imaging in hypertrophic cardiomyopathy: Is it a marker of myocardial injury?
Background Previous studies observed the phenomenon of high signal intensity on T2 -weighted image of cardiac magnetic resonance imaging (CMR) in hypertrophic cardiomyopathy (HCM). However, the underlying histopathologic mechanism is unclear. Elevated cardiac troponin can be detected in some HCM patients. A reasonable hypothesis is that myocardial T2-high signals is a potential marker of myocar...
متن کاملEvaluation of tissue doppler echocardiography and T2* magnetic resonance imaging in iron load of patients with thalassemia major
Background: Iron-mediated cardiomyopathy is the main complication of thalassemia major (TM) patients. Therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. The aim of this study was to evaluate the efficacy of tissue doppler imaging (TDI) to study cardiac iron overload in patients with TM using T2* magnetic resonance (MR) as the gold-standard...
متن کاملElevated high-sensitivity cardiac troponin is associated with hypertrophy and fibrosis assessed with CMR in patients with hypertrophic cardiomyopathy
Background High-sensitivity (hs) cardiac troponin is a valuable biomarker of myocardial injury and frequently elevated in patients with hypertrophic cardiomyopathy (HCM). Using cardiovascular magnetic resonance (CMR) the HCM phenotype can be characterized in great detail with fibrosis as a key finding with prognostic impact. Therefore, our aim was to investigate whether elevated troponin levels...

متن کاملComparison of Magnetic Resonance Imaging T2 Results in Beta-Thalassemia Patients Treated by Deferasirox or Combination of Deferoxamine and Deferiprone
Background: Iron extra load is an anticipated and lethal consequence of chronic blood transfusion in major beta-thalassemia patients; therefore it is necessary to use an efficient iron chelator drug to stimulate the evacuation of the surplus iron from the body. This trial was performed to compare myocardial and hepatic magnetic resonance imaging T2 (MRI T2*) results of beta-thalassemia patients...
