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 ...
Advancing age is an independent risk factor for cardiovascular disease. Matrix metalloproteinase-9 (MMP-9) is secreted by macrophages and robustly increases in the left ventricle (LV) with age. The present study investigated the effect of MMP-9 overexpression in macrophages on cardiac aging. We compared 16- to 21-mo-old C57BL/6J wild-type (WT) and transgenic (TG) male and female mice (n = 15-20...
BACKGROUND Endocrine functions of the heart have been well established. We investigated the hypothesis that cardiac secretion of a unique phospholipase A2 recently identified by our laboratory (cardiac secreted phospholipase A2 [sPLA2]) establishes a heart-liver endocrine axis that is negatively regulated by matrix metalloproteinase-2 (MMP-2). METHODS AND RESULTS In Mmp2(-/-) mice, cardiac (b...
OBJECTIVES Animal models of human Epstein-Barr virus (EBV) infection include EBV infection of primates and infection of mice with MHV-68, a further gamma herpesvirus (gamma-HV). We aimed at extending the MHV-68 model to study gamma-HV-related cardiac disease. METHODS Newborn wild-type BALB/c- (n=107), wild-type C57BL/6- (n=17) and immunodeficient B6-(Rag1) mice (n=18) were infected by nasal i...
AIM Cardiac inflammation is important in the pathogenesis of heart failure. However, the consequence of systemic inflammation on concomitant established heart failure, and in particular diastolic heart failure, is less explored. Here we investigated the impact of systemic inflammation, caused by sustained Toll-like receptor 9 activation, on established diastolic heart failure. METHODS AND RES...
Inflammation plays an important role in cardiac dysfunction under different situations. Acute systemic inflammation occurring in patients with severe burns, trauma, and inflammatory diseases causes cardiac dysfunction, which is one of the leading causes of mortality in these patients. Acute sepsis decreases cardiac contractility and impairs myocardial compliance. Chronic inflammation such as th...
Magnolia as an herbal material obtained from Magnolia officinalis has been found to play an important role in anti-inflammation, antioxidative stress, and antiapoptosis. This study was designed to investigate the effect of Magnolia extract (BL153) on obesity-associated lipid accumulation, inflammation, oxidative stress, and apoptosis in the heart. C57BL/6 mice were fed a low- (10 kcal% fat) or ...
OBJECTIVE Churg-Strauss syndrome (CSS) cardiac involvement is associated with a poor prognosis. Recently cardiac MRI (CMRI) has emerged as a promising technique to detect early CSS cardiac involvement. However, CMRI-detected myocardial delayed enhancement (MDE) could correspond to fibrosis or inflammation. Fluoro-2-deoxyglucose PET (FDG-PET) was previously used in other systemic diseases to dis...
