How much can pulmonary hypertension be operated on?

summary

Pulmonary hypertension is not uncommon in clinical practice. The word "pulmonary hypertension" can often be seen when reading cardiac ultrasound reports, but many people do not know its specific meaning. Now we share the latest classification and progress of pulmonary hypertension and pulmonary hypertension. Now let's talk about how much pulmonary hypertension can be operated on?.

How much can pulmonary hypertension be operated on?

First, pulmonary hypertension is not uncommon in clinical practice. The word "pulmonary hypertension" can often be seen when reading cardiac ultrasound reports, but many people do not understand its specific meaning.

Second: first of all, it should be clear how the pulmonary artery pressure is measured. At present, the commonly used clinical method is echocardiography estimation, that is, the maximum velocity of regurgitation is obtained by measuring the spectrum of tricuspid regurgitation, and then calculated by Bernoulli formula. Another estimation value is right atrial pressure. From this general description, we can also find that there is a certain deviation in echocardiography. The "gold standard" for the diagnosis of pulmonary hypertension is right heart catheterization for direct pressure measurement of the pulmonary artery.

Third, it is generally believed that the pulmonary artery pressure of normal people is 15-30 / 5-10 mmHg, with an average of 15 mmHg. According to who, pulmonary hypertension is defined as pulmonary artery systolic pressure exceeding 25 mmHg at rest. Echocardiography reports often describe mild, moderate (50-70 mmHg), severe (> 70 mmHg), of course, this is not absolutely uniform.

matters needing attention

1. Traditional treatment: calcium antagonists (if the right heart catheterization test is positive in acute pulmonary vasodilation test, the use of CCB drugs alone can achieve good results), lung transplantation. 2. Targeted therapy: prostacyclin (epoprost, beraprost sodium, iloprost, etc.), endothelin receptor antagonists (bosentan, alisentan, etc.), type 5 phosphodiesterase inhibitors (sildenafil, Viagra, tadalafil, etc.).
