Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Arterial oxygen tension is variable in patients with acute myocardial infarction, and the effect of hypoxemia on the extent of myocardial necrosis after coronary occlusion has not been defined. In 11 anesthetized open chest dogs the left anterior descending coronary artery or one of its major

In vivo delineation of myocardial hypoxia during coronary occlusion using fluorine-18 fluoromisonidazole and positron emission tomography: a potential approach for identification of jeopardized myocardium.

Ingia / Ingia

Reactive oxygen species play a central role in myocardial ischemic injury and are a target for therapeutic intervention. Vitamin C is an essential antioxidant yet difficult to deliver in pharmacologic concentration to the myocardium. We found that adult rat cardiomyocytes accumulate vitamin C by

Heterogeneous coronary perfusion during myocardial hypoxia.

The distribution of coronary flow during high-flow hypoxia and ischemia has been assessed in the perfused rat heart. Surface and cross-section NADH fluorescence photography defined the pattern of oxygen delivery because regions of high NADH fluorescence denote areas of anoxia. Thioflavin S, a

Increased affinity to substrate in sarcolemmal ATPases from hearts acclimatized to high altitude hypoxia.

Ingia / Ingia

It has been well documented that acclimatization to chronic high altitude hypoxia involves a complex of adaptation changes which are capable of protecting the myocardium in diverse situations such as in acute hypoxia, coronary occlusion-induced ischaemia or isoprenaline-induced calcium overload.

Comparative effects of ischemia and hypoxemia on left ventricular systolic and diastolic function in humans.

Ingia / Ingia

BACKGROUND During the initial phase of an ischemic insult, left ventricular (LV) performance depends on the complex interaction between oxygen deprivation, vascular turgor, and accumulation of metabolites. In experimental preparations, low-flow ischemia decreases systolic shortening and increases
