How does carbon monoxide cause heart disease?

Carbon monoxide (CO) contributes to Heart disease primarily by binding to hemoglobin in red blood cells more effectively than oxygen, reducing the oxygen supply to the heart and other tissues. This hypoxia can lead to increased heart rate and blood pressure, putting additional strain on the cardiovascular system. Prolonged exposure to CO can also promote the formation of plaques in the arteries, leading to atherosclerosis and increasing the risk of heart attacks and other cardiovascular events. Additionally, CO can induce inflammation and oxidative stress, further damaging the heart and blood vessels.
