Re: Pulmonary Edema Hypertension
The most common causes of PH are the heart's output does not meet the system demand causing pulmonary venous hypertension, and/or chronic hypoxia (oxygen deficiency) due to a chronic lung disease. There are other less common causes as well. Pulmonary venous pressure as well as pulmonary artery pressure are in mmHg (milimeters of mercury), the same as system's blood pressure measurement. I am not sure regarding calculations in % unless you are referring to blockage?!
The dx indicates two issues regarding heart and lung. There may be a connection between the two conditions where the lung issue is secondary to the heart issue. I believe there is a connection based on the brief history of the problems. A low cardiac output due to the heart's left ventricle pumping deficiency will influence pulmonary venous pressure and pulmonary artery pressure.
Another symptom of LV's low output will/could cause edema (retention of fluids) and the prescribed lasix should reduce ankle and foot swelling. The low cardiac output does not balance out with incoming blood from the lungs so there is a backup of blood and fluids get into the tissues and cause swelling. Often there is edema of the lungs that will cause a dry cough and breathing problems. To correct this imbalance would be medication to increase the heart's contractility, reduce afterload (dilate arteries) and reduce fluid retention. This should bring down hypertension.
The foregoing is only to give you some insight as I identify with some of the problems.
