How does smoking affect my heart and blood vessels?
The chemicals in tobacco smoke harm your blood cells and damage the function of your heart. This damage increases your risk for:
- Atherosclerosis, a disease in which a waxy substance called plaque builds up in your arteries
- Aneurysms, which are bulging blood vessels that can burst and cause death
- Cardiovascular disease (CVD), which includes:
- Coronary heart disease (CHD), narrow or blocked arteries around the heart
- Heart attack and damage to your arteries
- Heart-related chest pain
- High blood pressure
- Coronary Heart disease, where platelets—components in the blood—stick together along with proteins for form clots which can then get stuck in the plaque in the walls of arteries and cause heart attacks
- Peripheral arterial disease (PAD), a condition in which plaque builds up in the arteries that carry blood to the head, organs, and limbs
- Stroke, which is sudden death of brain cells caused by blood clots or bleeding
Breathing tobacco smoke can even change your blood chemistry and damage your blood vessels. As you inhale smoke, cells that line your body’s blood vessels react to its chemicals. Your heart rate and blood pressure go up and your blood vessels thicken and narrow.
