What Is Hypoxic Pulmonary Vasoconstriction?

Hypoxic pulmonary hypertension is caused by hypoxia caused by vascular endothelial cell damage. Imbalance of various vasodilation factors synthesized and secreted by vascular endothelium leads to early pulmonary vasoconstriction and later pulmonary vascular reconstruction. Hypoxic pulmonary vascular reconstruction is an important pathological basis for hypoxic pulmonary hypertension. For example, pulmonary hypertension is called pulmonary hypertension. In the early stages of the disease, patients often have no obvious subjective symptoms, and due to the limitation of measurement methods, hypoxic pulmonary hypertension is not easy to detect in time.
