What is the difference between arterial hypertension and pulmonary hypertension?

Peripheral vs Lung: Systemic arterial hypertension or just regular hypertension is elevated pressure in aorta or peripheral circulation (arms, legs). Pulmonary hypertension is elevated pressure in the pulmonary arteries in the lungs. Pulmonary hypertension usually has different causes, prognosis and much different treatment than systemic arterial hypertension.

Different entities: Arterial hypertension refers to high pressures in your systemic circulation (blood vessels in your entire body other than lung). Pulmonary hypertension refers to high pressures in the blood vessels that supply blood into the lungs. The two conditions are different & require different treatments. Please consult your doctor to get more information & tests that can be done to diagnose & treat them.

Good question: Nikita, pulmonary hypertension is an elevation of the pressures in the blood vessels in the lungs. Arterial hypertension( I am assuming systemic hypertension) is the elevation of the pressures in the arms. Pulmonary hypertension is very dangerous as it is caused by damage in the blood vessels in your lungs and the medications are very different from systemic hypertension.

PH and PAH: Pulmonary hypertension (PH) is often first detected by echocardiogram and may be caused by a variety of conditions. Pulmonary arterial hypertension (PAH) is caused narrowing of the small lung arteries and must be diagnosed by heart catheterization. PAH requires treatment by an expert specialist.
