Management of Pulmonary Hypertension: Associated with Left Heart Disease.

Pulmonary hypertension (PH) due to left heart disease, or WHO group 2 PH, is the most frequent cause of PH. It affects approximately 50% to 60% of patients with heart failure with preserved ejection fraction as well as 60% of those with heart failure with reduced ejection fraction and contributes significantly to disease progression and unfavorable outcomes. The diagnosis of PH is associated with poor prognosis and significant morbidity and mortality.
