WebJul 7, 2024 · In hypertension, capillary rarefaction induces an increase in blood pressure, a relative decrease in tissue perfusion and an increased cardiovascular risk. How do you assess tissue perfusion? Assessment of peripheral tissue perfusion is based on observing the temperature of the skin and the status of capillary perfusion and refill in the periphery. WebMicrovascular rarefaction is constantly observed in hypertension, and probably contributes to higher systemic resistance and lower tissue perfusion. Endothelial dysfunction leading to impaired arteriolar reactivity is also characteristic of the microvascular dysfunction in hypertensive patients. how many maps does bf4 have
