These include effects on arterial smooth muscle cells that cause intense peripheral vasoconstriction and stimulation of cardiac myocytes and fibroblasts. The latter promotes phenotypic changes in ...

Dilated pupils (mydriasis or fixed pupils) are when your eyes' pupils, which let light into your eyes, become wider. This can happen due to medications used during an eye exam (mydriatic drops), other ...

Maximal vasodilation can increase cutaneous blood flow to 3000 ml/minute (average flow is 300-500 ml/minute). 2. Vasoconstriction - decreases blood flow to periphery, decreases heat loss. Maximal ...

In the past decade there has been a growing interest in understanding sex and gender differences in myocarditis and dilated cardiomyopathy (DCM), and the purpose of this review is to provide an update ...

Maximal vasodilation can increase cutaneous blood flow to 3000 ml/minute (average flow is 300-500 ml/minute). 2. Vasoconstriction - decreases blood flow to periphery, decreases heat loss. Maximal ...

Endothelial dysfunction results in decreased production of endogenous vasodilatory mediators (nitric oxide and prostacyclin) and the upregulation of endothelin-1, which promotes vasoconstriction and ...

Electronic cigarettes or e-cigarettes are the most frequently used tobacco product among adolescents. Despite the widespread use of e-cigarettes and the known detrimental cardiac consequences of ...

In this relationship, acute alterations in vascular elasticity, vasoconstriction and reflected pulse waves lead to increases in cardiac work and contribute to decompensated LV function with associated ...

CFR in the absence of obstructive CAD can signify impaired microvascular dilation. Lance Gould first introduced this concept almost 50 ... The third mechanism of microvascular dysfunction is ...

The term dilated cardiomyopathy (DCM) refers to a spectrum of heterogeneous myocardial disorders that are characterized by ventricular dilation and depressed myocardial performance in the absence of ...

If you suffer from headaches but can't pinpoint why, it could be down to what you're eating. Tyramine—a natural compound found in plants and animals—is commonly found in many foods, and it ...
