Tobacco contains some of the deadliest chemical compounds that are known to cause chronic diseases. When we talk solely about heart disease, the nicotine in tobacco:
Raises your blood pressure
Speeds up your heart rate
Decreases the amount of oxygen in your blood
Increases the tendency for blood to clot
Damages your blood vessels
Forms plague in your arteries
Eventually, these conditions increase the risk of heart disease, thereby raising the chances of stroke or sudden death.
Impact of secondhand smoking
When you breathe in the air where anyone nearby is smoking a tobacco, it is called secondhand smoking. If you are frequently exposed to secondhand smoke, the nicotine in the smoke will affect your heart similarly as it does to a smoker’s heart. It can make your blood thicker and stickier, increase your bad cholesterol (LDL), and damage the lining of your blood vessels. All these changes can result in a heart attack or stroke.
