Pulmonary hypertension is high pressure in the blood vessels that carry blood into the lungs. This strains the lungs and heart and can lead to serious problems.
High blood pressure, or hypertension, increases the risk for coronary heart disease (heart attack) and stroke (brain attack). Read on for details about this condition.
Persistent pulmonary hypertension (PPHN) happens in newborn babies. It occurs when a newborn’s circulation continues to flow as it did while in the uterus. When this happens, too much blood flow bypasses the baby’s lungs. This is sometimes called persistent fetal circulation.
