Magnetic resonance imaging in the evaluation of non-ischemic cardiomyopathies: Current applications and future perspectivesHeart Failure Reviews - - 2006
Ilan Gottlieb, Robson Macedo, David A. Bluemke, João A. C. Lima
Patients with non-ischemic cardiomyopathy often represent a diagnostic challenge, and correct etiologic diagnosis may influence outcomes. Lately, delayed myocardial enhancement MR imaging has been developed and is currently being used for a growing number of clinical applications. On delayed enhancement MR images, scarring or fibrosis appears as an area of high signal intensity, and the pattern by...... hiện toàn bộ
Role of Angiotensin II in Hypertension-Induced Cardiac Hypertrophy and FailureHeart Failure Reviews - Tập 3 - Trang 159-168 - 1999
Tamá Csikós, Oliver Chung, Thomas Unger
Besides playing a role in blood-pressure regulation and salt and fluid homeostasis, the octapeptide angiotensin II mediates cell growth and differentiation. Its effects are dependent on angiotensin receptors, of which both AT1 and AT2 receptors are extensively described. In cardiac hypertrophy and heart failure, angiotensin receptors are differentially regulated. It is established that AT1 recepto...... hiện toàn bộ
Role of various proteases in cardiac remodeling and progression of heart failureHeart Failure Reviews - Tập 17 - Trang 395-409 - 2011
Alison L. Müller, Naranjan S. Dhalla
It is believed that cardiac remodeling due to geometric and structural changes is a major mechanism for the progression of heart failure in different pathologies including hypertension, hypertrophic cardiomyopathy, dilated cardiomyopathy, diabetic cardiomyopathy, and myocardial infarction. Increases in the activities of proteolytic enzymes such as matrix metalloproteinases, calpains, cathepsins, a...... hiện toàn bộ
A reappraisal of the pharmacologic management of gastrointestinal bleeding in patients with continuous flow left ventricular assist devicesHeart Failure Reviews - Tập 26 - Trang 277-288 - 2020
Audrey J. Littlefield, Gregory Jones, Alana M. Ciolek, Melana Yuzefpolskaya, Douglas L. Jennings
Advancements in the design and functionality of continuous flow left ventricular assist devices (CF-LVADs), as well as a limited number of donor hearts, have resulted in an increased utilization of this therapy among advanced heart failure (HF) patients. Despite these advancements, gastrointestinal bleeding (GIB) remains a common complication after CF-LVAD implantation. The mechanism of GIB in the...... hiện toàn bộ
Levels of angiotensin peptides in healthy and cardiovascular/renal-diseased paediatric population—an investigative reviewHeart Failure Reviews - Tập 24 - Trang 709-723 - 2019
F. K. Suessenbach, B. B. Burckhardt
The renin-angiotensin-aldosterone system (RAAS) plays a major role in the regulation of blood pressure and homeostasis. Therefore, it is a commonly used target for pharmacotherapy of cardiovascular diseases in adults. However, the efficacy of this pharmacotherapy can only be limitedly derived into children. Comprehensive knowledge of the humoral parameters acting in the paediatric RAAS (e.g. angio...... hiện toàn bộ
Arrhythmias and vagus nerve stimulationHeart Failure Reviews - Tập 16 - Trang 147-161 - 2010
Youhua Zhang, Todor N. Mazgalev
Enhancing vagal tone by delivering electrical stimulation to the vagal nerves (VNS) is emerging as a promising novel therapy in heart failure. In addition, VNS is already an FDA-approved therapy for refractory epilepsy and depression. Besides its well-known negative chronotropic, inotropic, and dromotropic effects, VNS has profound effects on cardiac electrophysiology and arrhythmogenesis. This re...... hiện toàn bộ
Autophagy protects mitochondrial health in heart failureHeart Failure Reviews - - 2023
Yating Tang, Wenlong Xu, Yu Liu, Jiajun Zhou, Kai Cui, Yanmei Chen
The progression of heart failure is reported to be strongly associated with homeostatic imbalance, such as mitochondrial dysfunction and abnormal autophagy, in the cardiomyocytes. Mitochondrial dysfunction triggers autophagic and cardiac dysfunction. In turn, abnormal autophagy impairs mitochondrial function and leads to apoptosis or autophagic cell death under certain circumstances. These events ...... hiện toàn bộ
Granulocyte colony-stimulating factor for ischemic heart failure: should we use it?Heart Failure Reviews - Tập 15 - Trang 613-623 - 2010
Marcelo Perim Baldo, Sérgio Lamêgo Rodrigues, José Geraldo Mill
Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic cytokine usually used in the treatment of patients with cancer. Studies have shown regenerative properties of bone marrow stem cell mobilization due to G-CSF in animals. Moreover, others effects related to G-CSF and independent of tissue regeneration were shown to be protective. As a result, this cytokine has been tested as a therapy...... hiện toàn bộ
