Patient's question:
What causes pulmonary hypertension? Recently, I've been unclear about what's going on. After a bit of exercise, I feel dizzy and chest tightness. An ECG didn't show anything significant, but my blood pressure was high. In the end, a CT scan revealed that the dizziness was caused by pulmonary hypertension. My relative doesn't quite understand, how could someone so young have such a disease? What causes pulmonary hypertension?Doctor's answer:
Pulmonary hypertension lacks specific clinical diagnostic symptoms. In the early stages, patients may have no symptoms or only exhibit the clinical manifestations of the primary disease. As pulmonary artery pressure decreases, many non-specific symptoms may appear, such as exertional dyspnea, fatigue, abdominal pain, angina, syncope, etc. Due to the decrease in pulmonary artery pressure, signs of right atrial and right ventricular hypertrophy may occur, such as a tense P2, a holosystolic murmur caused by tricuspid regurgitation, a diastolic murmur caused by pulmonary valve insufficiency, and the second heart sound of the right ventricle.
