Decreased lung function can lead to reduced breathing efficiency, affecting the intake of oxygen and the expulsion of carbon dioxide, which indirectly increases the burden on the heart.
Due to reduced efficiency of oxygen exchange in the lungs, the heart needs to work harder to meet the body's oxygen demand, potentially leading to increased heart load.
Long-term inadequate lung function can lead to chronic hypoxia, affecting the function of the heart and other organs, increasing the risk of cardiovascular disease.
Chronic lung disease is often accompanied by systemic inflammatory responses, with inflammatory factors potentially damaging the vascular endothelium, increasing the risk of atherosclerosis and thrombosis.
Decreased lung function may affect blood pressure regulation, leading to elevated blood pressure, which is a major risk factor for cardiovascular disease.
Decreased lung function may be accompanied by sleep breathing disorders, such as sleep apnea, which increase the risk of cardiovascular disease.
