Some studies show that getting enough calcium might decrease the risk of heart disease and stroke. Other studies find that high amounts of calcium, particularly from supplements, might increase the risk of heart disease. But when all the studies are considered together, scientists have concluded th...
Sinus bradycardia, large QRS voltages, modest increases in left and right ventricular cavity size and high peak oxygen consumption are well-recognized features of an endurance athlete’s heart. Some lifelong endurance athletes have an increased prevalence of high coronary artery calcium scores, myocardia...
摘要: If one were to attempt a study of the invertebrate heart muscle, the preparation which would immediately come to mind would be the classical clam heart preparation. Almost 30 years ago Prosser关键词:Muscles Myofibrils Myocardium Heart Animals Mollusca Sodium Calcium Physiology, Comparative ...
we review current knowledge on the direct and indirect effects of these amphetamine congeners on the mammalian heart—more specifically, the isolated human heart muscle preparation
Calcium is an essential nutrient for skeletal health; however, it has been suggested that supplemental calcium may be associated with adverse cardiovascular effects, raising widespread concern about their use. One suggested mechanism is via increasing carotid atherosclerosis, however few randomized controlled...

Changes in intra-luminal calcium during spontaneous calcium waves following sensitization of ryanodine receptor channels Cardiac contraction during systole is dependent on action potential-triggered Ca2+ release from the sarcoplasmic reticulum (SR) through ryanodine receptor (RyR) channels. SR Ca2+ release ...
