Smoking Harms the Heart!

Smoking forces the heart to work harder by reducing the oxygen supply to the heart muscle. It causes the heart to beat faster and increases blood pressure, resulting in narrowing of the coronary arteries. Tobacco smoke contains numerous toxic substances that damage the walls of blood vessels and contribute to cardiovascular disease.

1. Nicotine

Nicotine is the primary substance responsible for the harmful effects of smoking. It contributes to:

- Increased blood pressure

- Increased heart rate

- Coronary artery vasoconstriction

- Reduced blood supply to the heart muscle

- Increased oxygen demand by the heart

- Faster blood clot formation

2. Carbon Monoxide

Carbon monoxide reduces the oxygen-carrying capacity of the blood, causing the heart to beat faster and work harder. It may lead to chest pain and increases blood pressure due to reduced oxygen delivery to the heart.

The World Health Organization (WHO) reports that 25% of deaths from coronary heart disease are attributable to smoking. Both active smokers and individuals exposed to secondhand smoke are at increased risk of cardiovascular disease.
