Smoking seriously affects the cardiovascular system.

Smoking not only causes serious respiratory problems and lung cancer, but is also a major risk factor for cardiovascular disease.

According to statistics, one in five deaths from heart disease is directly related to smoking. Medical experts say that cigarette smoke contains many toxic substances that not only damage the lungs but also have a negative impact on cardiovascular health, increasing the risk of heart disease and stroke.

Cigarette smoke contains more than 7,000 chemicals, many of which are harmful to the heart.

According to Associate Professor, Dr. Vu Van Giap, Deputy Director of Bach Mai Hospital, cigarettes contain many toxic substances that seriously affect the health of smokers and those around them.

These toxins accelerate the process of atherosclerosis, causing arteries to harden and narrow, impeding blood flow to the heart and other vital organs.

When you smoke, the chemicals in cigarette smoke constrict your blood vessels, leading to a temporary and long-term increase in blood pressure. Chronic high blood pressure is one of the major risk factors for cardiovascular disease.

In fact, each cigarette can cause a smoker's blood pressure to rise for a short period of time after smoking, and if this condition persists, it can lead to severe hypertension.

Cigarette smoke contains more than 7,000 chemicals, many of which are harmful to the heart. Nicotine increases the level of bad cholesterol (LDL) in the blood, while decreasing the level of good cholesterol (HDL).

This process causes plaque to form in the arteries, leading to blockages and increasing the risk of heart attack, especially in people who already have underlying heart disease.

The harmful effects of smoking are not limited to the heart, but also affect the ability of blood to circulate to the brain. Smokers are at high risk of stroke due to blockage of blood vessels in the brain. Cigarette smoke also makes the blood more likely to clot, creating a blood clot and blocking the blood vessels in the brain, leading to stroke.

Although quitting smoking can reduce your risk of heart disease, the damage to your heart from smoking can last for years after you quit. It can take a long time for your heart to recover, and former smokers remain at higher risk of heart disease than people who have never smoked.

Smoking not only increases the risk of lung cancer, but also increases the risk of serious cardiovascular diseases such as stroke and heart attack.

Quitting smoking is a necessary decision to protect cardiovascular health and reduce dangerous diseases. To reduce the harmful effects of tobacco on public health, it is very important to increase propaganda about the negative effects of tobacco and support people to quit smoking.
