警惕潜伏在身体里的“隐形杀手” 预防肺动脉高压注意这几点

Group 1 - The core issue of pulmonary arterial hypertension (PAH) is its high misdiagnosis rate and subtle symptoms, making it a "silent killer" [1][2] - PAH is characterized by increased pulmonary vascular resistance and elevated pulmonary artery pressure, which can lead to right heart failure and death if untreated [2] Group 2 - Symptoms of PAH are non-specific and may include shortness of breath after activity, cyanosis (blue lips) due to chronic hypoxia, decreased appetite, abdominal bloating, and edema in the lower limbs [4][5][6] - Severe cases may also present with hair loss, photosensitivity, oral ulcers, and arthritis [6] Group 3 - Prevention strategies for PAH include avoiding prolonged sitting to prevent deep vein thrombosis, which can lead to pulmonary embolism and subsequently PAH [12] - Smoking cessation is crucial as it damages pulmonary vascular endothelial cells, increasing the risk of PAH [13] - Regular health check-ups are important for high-risk individuals, such as those with a family history of PAH or related underlying conditions, to detect early signs of the disease [15]
