How does smoking affect heart health?

Smoking has a detrimental impact on heart health. It damages the lining of blood vessels and leads to the buildup of plaque, which can cause atherosclerosis (hardening of the arteries). This increases the risk of heart disease and heart attacks. Additionally, smoking can raise blood pressure and reduce the level of oxygen in the blood, further straining the heart. Quitting smoking can significantly improve heart health and reduce these risks. The NHS offers support services and resources to help individuals quit smoking.
