Potassium depletion and cardiac hypertrophy: how does it work?
For a number of years, many clinicians have believed that potassium depletion should be avoided in the treatment of hypertension, and that potassium supplementation might be advantageous in such patients.1 The Dietary Approaches to Stop Hypertension (DASH) diet, a diet that is low in sodium and replete with potassium, is now being recommended as a standard lifestyle modification for patients wi...
متن کاملRemodeling of Potassium Channels in Cardiac Hypertrophy
B.I. Jugdutt and N.S. Dhalla (eds.), Cardiac Remodeling: Molecular Mechanisms, Advances in Biochemistry in Health and Disease 5, DOI 10.1007/978-1-4614-5930-9_2, © Springer Science+Business Media New York 2013 Abstract The potassium channel is a major target of remodeling in cardiac hypertrophy. To maintain physiological cardiac function in the face of increased workloads, hypertrophied cardiac...
متن کاملDetection of Cardiac Hypertrophy by RVM and SVM Algorithms
The meaning of the hypertropy word is the increasing size.Heart hypertropy is symptoms of increase the thickness of the heart muscle that the left ventricular hypertrophy of them is the most common.The causes of hypertrophy heart disease are high blood pressure , aortic valve stenosis and sport activities respectively. Assessment of that by using ECG signal analysis is essential Because the ris...
متن کاملPotassium depletion and diastolic dysfunction.
Changes in extracellular potassium concentration affect nearly all aspects of myocardial function. Reductions in potassium concentration alter the resting membrane potential, membrane conductance for sodium and potassium, repolarization time, relative refractory time, and conduction velocity. The arrhythmogenic consequences of these effects of potassium depletion are well recognized by the medi...
متن کاملMitochondria and cardiac hypertrophy.
• Normally, myocardial metabolism is almost exclusively aerobic. The substantial quantities of adenosine triphosphate (ATP) required for muscle contraction and the much smaller amounts necessary for the maintenance of functions such as ion transport, rhythmicity, and conduction and the synthesis of membrane and protein constituents of the myocardium are supplied almost exclusively by mitochondr...
