However, do you also know that you are likely to suffer from a heart attack through smoking? 

You are likely to have heart disease from every cigarette you smoke. 

Smoking is related to 2 out of 10 deaths from heart disease.

In the United States, close to 20% of all deaths caused by heart disease are related to smoking cigarettes. 

Smoking is even worst for ladies who smoke and swallow pills to control birth. Those who don’t smoke but stay around you as you smoke are also at risk.

Secondhand smoking (means someone else is smoking and you are passively inhaling the smoke) can cause lung cancer and heart disease. Let’s see how secondhand smoking can relate to heart disease. 

Relationship between Secondhand Smoking and Heart Disease 

Secondhand smoke is smoke exhaled by a smoker’s burning tobacco products. It leads not only to coronary heart disease but also heart attack and stroke.

More than 35,000 early deaths per year from coronary heart disease in the United States of America are caused by secondhand smoke.

Over 8000 deaths from stroke are caused by exposure of nonsmokers to smoke. By 20-30%, nonsmokers are at risk of having a stroke. 

The blood, arteries, veins and heart functions are affected by secondhand smoke.

You increase the risk of getting heart disease up to 30% when you inhale smoke from a smoker’s tobacco. This increases your chance of getting heart disease. 

How Smoking Leads to Heart Disease?

A substance known as nicotine and the free radical that gets delivered through the smoke cause the following: 

  • Increases your blood pressure. 
  • Your heart rate increases. 
  • The oxygen level your heart gets is reduced. 
  • The inner parts of your blood vessels are affected. Those of your heart are included. 
  • Blood clots are more than before leading to both heart attacks and strokes. 
  • More atherosclerosis (the cholesterol filled damaged cells, that get collected inside the heart arteries) thus more heart attack.
