Pulmonary hypertension secondary to left-heart failure is categorized as which group?

Pulmonary hypertension is categorized by where the problem lies. When left-heart failure raises the left atrial pressure, that pressure backs up into the pulmonary veins and capillaries, producing a postcapillary form of PH. This means the issue is due to left-sided heart disease, not the pulmonary arteries themselves. It’s characterized by elevated pulmonary capillary wedge pressure and often a normal or only mildly elevated pulmonary vascular resistance, reflecting venous, not arterial, involvement. This distinguishes it from PH caused by lung disease or hypoxia, chronic thromboembolic disease, or primary pulmonary arterial remodeling. So, the category for pulmonary hypertension in the setting of left-heart failure is the PH type due to left-sided heart disease.
