rvsp pulmonary hypertension grading

Pulmonary arterial hypertension (PAH) is classified into mild, moderate, and severe categories based on the right heart catheterization measurement of pulmonary artery systolic pressure (RVSP). Mild PAH is characterized by an RVSP between 25 and 35 mmHg, moderate PAH by an RVSP between 36 and 45 mmHg, and severe PAH by an RVSP over 45 mmHg.

Clinically, mild PAH is more frequently observed, with patients potentially being asymptomatic or only experiencing shortness of breath during intense physical activity. As the disease advances, patients with moderate PAH may develop symptoms such as reduced exercise tolerance, fatigue, and chest pain. Severe PAH patients may present with critical symptoms like severe shortness of breath, syncope, and peripheral edema, which can significantly impair their quality of life.

For individuals with PAH, it is essential to avoid vigorous exercise and overexertion, and to maintain healthy lifestyle practices, including smoking cessation, alcohol moderation, and a balanced diet. Regular monitoring of blood pressure and cardiac function is also crucial, along with adhering to prescribed treatments and not self-administering medication without guidance. Should symptoms such as worsening shortness of breath or chest pain occur, immediate medical consultation is advised.
