Pulmonary Hypertension


Pulmonary arterial hypertension (PAH) is a chronic disease characterized by increased pressure in the arteries of the respiratory system, caused by their reduction and blockage, enlarging the right ventricle of the heart, which decreases its ability to pump blood to the lungs.

Patients tend to suffer from the following symptoms:

  • Dyspnea or shortness of breath when resting and when engaged in physical activity.

  • Chest pain

  • Fatigue

  • Cyanosis: Bluish color in the lips and in the skin

  • Fast heart rate (palpitation)

  • Dizziness and fainting

  • Increased volume in legs and ankles (swelling)

At Alpha Research Institute, this condition is studied with the goal of improving the quality of life of our patients. If you have been diagnosed, please volunteer in our clinical trial by filling out the form. Voluntary donors and/or participants must be at least 18 years old, they have to be diagnosed by a doctor or specialist (cardiologist) and be totally free of infectious diseases (HIV, Syphilis, Hepatitis B and C).


For participating in the study they can receive a monetary compensation of $50 and free transportation throughout the Houston area.
