Pulmonary hypertension

Pulmonary arterial hypertension; Sporadic primary pulmonary hypertension; Familial primary pulmonary hypertension; Idiopathic pulmonary arterial hypertension; Primary pulmonary hypertension; PPH; Secondary pulmonary hypertension; Cor pulmonale - pulmonary hypertension

Pulmonary hypertension is high blood pressure in the arteries of the lungs. It makes the right side of the heart work harder than normal.

Respiratory system

Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.

Primary pulmonary hypertension

Pulmonary hypertension is the narrowing of the pulmonary arterioles within the lung. The narrowing of the arteries creates resistance and an increased work load for the heart. The heart becomes enlarged from pumping blood against the resistance. Some symptoms include chest pain, weakness, shortness of breath, and fatigue. The goal of treatment is control of the symptoms, although the disease usually develops into congestive heart failure.

Normal anatomy

The heart and lungs are located in the thorax, or chest cavity. The heart pumps blood from the body to the lungs, where the blood is oxygenated. It then returns the blood to the heart, which pumps the freshly oxygenated blood to the rest of the body.
