Hellenic Pulmonary Hypertension is a nonprofit organisation founded in 2013 by the initiative of patients with Pulmonary Hypertension*. It is a association of patients and caregivers who represent all sufferers of Greek and Cyprian territory with Pulmonary Hypertension. We provide all medical resources and ideal conditions for patients and their families.For our patients and caregivers who live outside Athens and come for treatments, we provide them our guest house and we helped them for their stay throughout the duration of their therapy. In these difficult times of COVID-19 our needs have increased and we need your support to continue helping whoever needs us.
*Pulmonary Hypertension (P.H) has nothing to do with hypertension. Hypertension is the increase of blood pressure within the arteries of the entire body except the lung arteries. On the contrary, the Pulmonary Hypertension involves only the lungs arteries.
The arteries of the lungs react differently from the other arteries of the body. For example, the reduction of blood oxygen causes vasodilation of the arteries of the body and vasoconstriction of the arteries of the lungs.
This explains why climbing at a tall mountain with an altitude of over 1,000 meters, where the atmospheric air has a lower oxygen content, creates conditions of vasodilation in peripheral vessels resulting to the decrease of blood pressure and causes pulmonary vasoconstriction of blood vessels leading to increased pulmonary pressure.
The normal pressure of blood within the arteries of lungs does not exceed 20-25 mmHg. At a healthy person, the pressure increases approximately up to 20 mm Hg (millimeters of mercury ) and decreases up to 5 mm Hg. Pulmonary artery pressure (often indicated as mPAP [middle pulmonary artery pressure]) is the average of the higher and lower pressures. Diagnosis of pulmonary hypertension is set if the middle pulmonary artery pressure exceeds 25mmHg at rest, with normal pressure in the pulmonary capillaries during right heart tubing The increase in pulmonary pressure can reach and surpass the levels of blood pressure, which means to reach and surpass the 120 mmHg.
