Smoking and Heart Disease
Transcript of Smoking and Heart Disease
Coronary heart disease (CHD) is a narrowing of the small blood vessels that supply blood and oxygen to the heart. CHD is also known as coronary artery disease. There are many different causes but the main cause of this fatal heart disease is smoking. It may also be caused by bad genes (hereditary), diabetes, high blood pressure, kidney diseases, metabolic syndrome, atherosclerosis. There are several types of heart disease, but the major ones are the atherosclerosis, coronary, rheumatic, congenital, myocarditis, angina, and arrythmia heart disease. Every 7 minutes, someone in Canada will die from heart disease. Did you know...? ■A heart attack occurs about every 20 seconds with a heart attack death about every minute.
■Almost 14 million Americans have a history of heart attack or angina.
A heart attack is when blood vessels that supply blood to the heart are blocked, preventing enough oxygen from getting to the heart. The heart muscle dies or becomes permanently damaged. Most heart attacks are caused by blood clots in yourcoronary arteries.
Angina, is a medical condition and a person suffering from angina is usually concious that they have it. They will most likely have medication on them and can administer it themselves, this is not usually a life threatning disease but can be very dangerous if not diagnose or not aware you are suffering from it.

lose weight Arrythmia= when your heart is beating at an irregular beat due to excessive smoking. CAD= when artery vessels are blocked and form blood clotting Heart attack= when the heart is always pumping and in constant need of oxygen, resulting in swelling in the arteries as the elastic like walls found in the heart, deflate and weaken. Arrythmia is when your heart beats at an irregular beat, either too fast or too slow. Arrythmia can be prevented by keeping youself healthy. This means no smoking, staying physically active (staying active is key to maintaining a healthy heart) and eating healthy.
Some factors that cause arrythmia are coronary artery disease (a heart disease that can be caused by smoking), injuary to the heart due to past heart failure (heart attack, angina), irregular heart beat. These are some of the affects smoking has all over your body. Other affects include: wrinkles, hard of breathing, sickness, bad/ yellow teeth, bad breath, cancers and diseases of all sorts.
•Nicotine, the drug that makes tobacco addictive, goes to your brain very quickly.
•Nicotine makes you feel good when you are smoking, but it can make you anxious, nervous, moody, and depressed after you smoke.
•Using tobacco can cause headaches and dizziness.
•Tobacco stains your teeth and gives you bad breath.
•Tobacco ruins some of your taste buds, so you won't be able to taste your favorite foods as well.
•Tobacco causes bleeding gums (gum disease) and cancers of the mouth and throat.
•Smoking increases your heart rate and blood pressure and causes heart disease and heart attacks.
•If you try to do activities like exercise or play sports, your heart has to work harder to keep up.
•Smokers have trouble breathing because smoking damages the lungs.
•If you have asthma, you can have more frequent and more serious attacks.
•Smoking causes a lot of coughing with phlegm (mucous).
•Tobacco can cause emphysema (lung disease) and lung cancer.
•Smoking causes dry, yellow skin and wrinkles.
•The smell sticks to your skin.
•Less blood and oxygen flows to your muscles, which causes them to hurt more when you exercise or play sports What's in them? There are over 559 additives in cigarettes, all extremely harmful to your body. The smoke that comes from a cigarette contains over 4,000 chemicals, including 43 known cancer-causing (carcinogenic) compounds and 400 other toxins. Some of theses chemicals include nicotine, tar, and carbon monoxide, as well as formaldehyde, ammonia, hydrogen cyanide, arsenic, and DDT. Nicotine is extremely addicting and reaches your brain in only 6 seconds! List of additives Nicotine
Nicotine is the main addictive ingredient in tobacco. It is readily absorbed into the blood and gives a hit (a rush) to the brain in about 10 seconds. Nicotine produces chemicals in the brain called dopamine. It is the regular hits of nicotine that the brain comes to expect and when people quit it causes withdrawl symptoms. Nicotine is a stimulant that increases the heart rate and blood pressure - this is partly a sign that the body is trying to absorb more oxygen.
That’s the stuff used as a solvent to remove nail varnish.
Ammonia speeds up the delivery of the nicotine. It freebases the nicotine in the same way as a crack user takes cocaine.
Tar is deposited into the lungs every time a person inhales. Smoking 20 or more cigarettes a day deposits 1 to 1.5 pounds into the lungs every year
Used as a solvent in fuel & dyes. Known to cause cancer.
Used to make batteries, cadmium is known to cause kidney damage. It increases the risk of developing lung cancer.
This is the same chemical pushed out by cars. It prevents the blood carrying oxygen around the body. A heavy smoker’s ability to carry oxygen around the body is reduced by up to 15%.
Yet another gas that reduces the body’s ability to carry oxygen around the body.
Pyridine is a central nervous system depressant that boosts the effect of smoking.
Here are a few main and dangerous additives found in cigarettes and cigars. •As many as 2 million Americans are living with atrial fibrillation, a type of arrhythmia.
•During a 24-hour period about 20% of healthy adults are likely to have multiple types of premature ventricular beats. Did you know...? Facts Smoking causes more than 440,000 of the more than 2.4 million annual deaths in the United States of America. Number 1 preventable cause of death in the world. A person’s risk of heart attack and disease is greatly increased with the number of cigarettes he or she smokes. There is no safe amount of smoking. Smokers continue to increase their risk of heart attack the longer they smoke. People who smoke a pack of cigarettes a day have more than twice the risk of heart attack than nonsmokers.
Link between smoking and heart disease More than 40,000 Canadians, aged 35 or more, are estimated to die annually as a direct result of smoking (30,000 men, 16,000 women).
Cigarettes and other forms of tobacco are addictive. Smoking is both a psychological and a physical addiction. Nicotine is one of the most highly addictive substances known.
The average additional annual cost to an employer of employing a smoker has been estimated by the Conference Board of Canada to be $2,565 (Conference Board of Canada, 1997). Second-hand smoke or environmental tobacco smoke is a toxic mixture of chemicals produced during the burning and smoking of tobacco products.
