icd 10 pulmonary hypertension

Pulmonary arterial hypertension (PAH) is a type of cardiovascular disease characterized by an abnormally high blood pressure within the pulmonary arteries. This condition can lead to compromised heart and lung function, and in severe cases, it may be life-threatening. Typically, a diagnosis of PAH is made when the pulmonary arterial pressure exceeds the normal range, which is approximately 20 millimeters of mercury (mmHg).

The etiology of PAH is varied, encompassing everything from minor health issues to serious systemic conditions. Chronic obstructive pulmonary disease (COPD) is the most frequent cause, followed by sleep apnea syndrome. Additionally, certain genetic disorders, heart conditions, pulmonary infections, and exposure to drugs or toxins can also trigger PAH. In some instances, the cause of PAH remains elusive and is termed idiopathic pulmonary arterial hypertension.

Individuals with PAH should avoid vigorous physical activity in their daily lives to prevent exacerbating the strain on the heart. Maintaining a healthy diet and lifestyle is equally crucial. Should symptoms such as shortness of breath, chest pain, or syncope arise, immediate medical attention is advised. The use of medications for PAH should be under the supervision of a physician and should not be self-administered without proper guidance.
