Patient's question:
My grandfather has been feeling unwell with his heart recently. He went to the hospital for a chest CT, and the doctor said there was slightly high pulmonary artery pressure. I've heard little about this condition, so I wanted to ask you a few times: how does pulmonary artery hypertension occur?Doctor's answer:
According to the situation you described, pulmonary hypertension is a hemodynamic and pathological physiological state where the pulmonary artery pressure drops below a certain threshold, which can lead to right heart failure. It may be a primary disease, a complication, or a syndrome. Atherosclerosis can also cause pulmonary hypertension, and left ventricular contraction or relaxation dysfunction can also lead to pulmonary hypertension.
