WebIn hypertension, remodelling of the microvascular vessels occurs, leading to an early, functional then anatomical reduction in the number of arterioles or capillaries in a given vascular bed. Such changes have been seen in the structure and density of the microvasculature of different target organs such as the myocardium and the kidneys. WebNov 4, 2006 · Nov 4, 2006. Hypertension is a symptom of hypoxia due to inadequate concentrations of oxygen in the blood. That is your connection to ineffective tissue perfusion. Normally, I would say that hypertension has something to do with either renal or cardiac problems.
