Myocardial supply and demand.

Myocardial supply and demand.

Ranolazine and the myocardial demand-supply balance.

Early studies of ranolazine centered on reductions in myocardial oxygen demand produced by partial inhibition of fatty acid oxidation, particularly as free fatty acid levels increase locally during ischemic episodes. More recent studies report that this mechanism is unlikely to be operative at the plasma levels of ranolazine associated with beneficial clinical effect. A reduction in myocardial ...

supply and demand security of energy in central asia and the caucasus

امنیت انرژی به معنی عرضه مداوم و پایدار همراه با قیمت های معقول در حامل های انرژی، که تهدیدات امنیتی، سیاسی، اقتصادی، محیط زیستی و روانی را کاهش دهد. امروزه نفت و گاز تنها، کالای تجاری نیست بلکه بعنوان ابزار سیاسی مورد استفاده قرار می گیرد.اختلاف میان روسیه و اکراین بر سر انرژی در ژانویه 2006، تهدیدی برای امنیت انرژی اروپا ایجاد کرد. در این تحقیق ما تلاش کردیم که نقش انرژی آسیای میانه و قفقاز ر...

Inadequate Myocardial Oxygen Supply/Demand in Experimental Pulmonary Hypertension

The increased workload of the right heart due to pulmonary hypertension increases oxygen consumption of right ventricular cardiomyocytes because the mitochondria have to operate at a higher rate. Hypertrophy can normalize right ventricular wall stress, thereby also normalizing the rate of oxygen consumption by mitochondria. However, hypertrophy may cause hypoxia in cardiomyocytes because intrac...
