Mitochondrial damage is associated with histologic myocardial fibrosis. Late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) can be used to identify focal fibrosis. We examined whether myocardial fibrosis on CMR and collagen volume fraction (CVF) from biopsies correlated with left ventricular (LV) and mitochondrial function in patients with nonischemic dilated cardiomyopathy (DCM).

Diffuse myocardial fibrosis is involved in the pathology of nonischemic cardiomyopathy (NIC). Recently, the application of native (noncontrast) myocardial T1 measurement has been proposed as a method ...
Cardiac MRI is unique amongst the cardiac imaging modalities in its ability to directly image myocardial fibrosis using late gadolinium enhancement techniques. The ability to identify not only the pre...
Prognostic value of myocardial fibrosis in patients with non-ischemic idiopathic dilated cardiomyopathy (DCM) is not well-defined. We sought to assess the association of focal and diffuse myocardial f...
BACKGROUND To study the role of Parkin in the regulation of mitochondrial autophagy in the heart by assessing mitochondrial autophagy and changes in Parkin protein expression in rat myocardium after m...
Cardiomyopathy caused by lamin A/C gene mutations (LMNA cardiomyopathy) is characterized by increased myocardial fibrosis, which impairs left ventricular relaxation and predisposes to heart failure, a...
Hypertension and aortic stenosis are the two leading conditions that cause thickening of the heart muscles (left ventricular hypertrophy). Left ventricular hypertrophy is initially adaptiv...
Assessment of Coronary Endothelial Function and Myocardial Fibrosis in Positron Emission Tomography With the Waning of Acute Coronary Syndrome With Elevated ST Segment : Relationship With Left Ventricular Remodeling
Context. The patients treated for acute coronary syndrome with ST segment elevation (STEMI) may have the waning of the episode left a deleterious ventricular remodeling can lead to heart f...
The purpose of this study is to compare changes in global left ventricular (LV) function after 3 months of treatment with irbesartan compared with usual care in patients with acute myocard...
This is a cross-sectional study of post myocardial infarction patients which is designed to determine the prevalence of left ventricular thrombi (blood clots) using non-contrast echocardio...
Myocardial deformation imaging allows analysis of myocardial viability in ischemic left ventricular dysfunction. This study will evaluate the predictive value of myocardial deformation ima...
Diabetes complications in which VENTRICULAR REMODELING in the absence of CORONARY ATHEROSCLEROSIS and hypertension results in cardiac dysfunctions, typically LEFT VENTRICULAR DYSFUNCTION. The changes also result in myocardial hypertrophy, myocardial necrosis and fibrosis, and collagen deposition due to impaired glucose tolerance.
Rare congenital cardiomyopathies characterized by the lack of left ventricular myocardium compaction. The noncompaction results in numerous prominent trabeculations and a loose myocardial meshwork (spongy myocardium) in the LEFT VENTRICLE. Heterogeneous clinical features include diminished systolic function sometimes associated with left ventricular dilation, that presents either neonatally or progressively. Often, the RIGHT VENTRICLE is also affected. CONGESTIVE HEART FAILURE; PULMONARY EMBOLISM; and ventricular ARRHYTHMIA are commonly seen.
A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
A form of CARDIAC MUSCLE disease in which the ventricular walls are excessively rigid, impeding ventricular filling. It is marked by reduced diastolic volume of either or both ventricles but normal or nearly normal systolic function. It may be idiopathic or associated with other diseases (ENDOMYOCARDIAL FIBROSIS or AMYLOIDOSIS) causing interstitial fibrosis.
A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).
