Pulmonary hypertension in pregnancy is a challenge for obstetricians, since due to the changes that occur during pregnancy, this underlying disease can be aggravated. It even leads to death, both of the mother and the fetus.
The prognosis is always reserved, but fortunately it is a rare disease in the general population. However, despite medical advances in its approach, there is still a maternal mortality of 30 to 50%.
What is pulmonary hypertension?
In pulmonary hypertension there is an obstruction or occlusion of the branches of the pulmonary artery. This blood vessel carries blood from the right ventricle to the alveoli, allowing carbon dioxide to escape to the outside and oxygenating itself to return to the left side of the heart.
Due to the obstruction, whatever the cause, the blood cannot continue its path and remains stagnant in the right ventricle, which has to expel it with a greater force. Over the years, with this unsustainable situation, the heart on the right side fails and heart failure ensues.
The fact of not being able to pass blood through the lungs and that it does not reach the left ventricle, means that the person does not have well oxygenated organs, causing shortness of breath, tiredness, fatigue and even fainting. Without proper treatment, pulmonary hypertension leads to death.
