Hypertension In Hypoxia

Hypertension is a pathophysiological condition, when arterial blood pressure is elevated. The heart works harder to overcome the increased systemic pressure in order to maintain blood flow to cells and tissues. Over time, the additional strain on the heart and arteries slowly leads to deadly sequelae such as congestive heart failure, myocardial infarction, pulmonary embolism, cerebral aneurysm and kidney failure(1). Primary hypertension is the most frequent, accounts about 90-95% incidences. It is associated with many factors such as sedentary lifestyle, stress, tobacco smoking, diabetes, high salt intake, potassium deficiency and sodium sensitivity, obesity, alcohol intake and vitamin D deficiency(2, 3). Other hand, secondary hypertension is less frequent, and is linked to mainly dysfunctions and disorders associated with central nervous system, kidneys, lungs, vascular and endocrine system(4).
