Smoking and Heart Disease Introduction
A person's risk of heart disease and heart attack greatly increases with the number of cigarettes he or she smokes. 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. Women who smoke and also take birth control pills increase several times their risk of heart attack, stroke, and peripheral vascular disease.
Cigarette smoke not only affects smokers. When you smoke, the people around you are also at risk for developing health problems, especially children. Environmental tobacco smoke (also called passive smoke or secondhand smoke) affects people who are frequently around smokers. Secondhand smoke can cause chronic respiratory conditions, cancer, and heart disease. It is estimated that around 35,000 nonsmokers die from heart disease each year as a result of exposure to environmental tobacco smoke.

There's no one way to quit smoking that works for everyone. To quit, you must be ready both emotionally and mentally. You must also want to quit smoking for yourself and not to please your friends or family. It helps to plan ahead. This guide may help get you started.
What Should I Do First to Stop Smoking?
Pick a date to stop smoking and then stick to it.
Write down your reasons for quitting smoking. Read over the list every day, before and after you quit. Here are some tips to think about.

smoke. You will learn what triggers you to smoke.

break or after dinner) before actually quitting.

something else when you want to smoke.

or better yet, to quit with you.
- Don't focus on what you are missing. Think about the healthier way of life
you are gaining.

and release it slowly. Repeat this several times until the urge to smoke is

movies, museums, shops, or libraries.
- Don't substitute food or sugar-based products for cigarette smoking. Eat
low-calorie, healthful foods (such as carrot or celery sticks, sugar-free hard
candies) or chew gum when the urge to smoke strikes so you can avoid weight
- Drink plenty of fluids, but limit alcoholic and caffeinated beverages. They
can trigger urges to smoke.
- Exercise. Exercising will help you relax.
- Get support for quitting. Tell others about your milestones with pride.
- Work with your doctor to develop a plan using over-the-counter or prescription nicotine-replacement aids.
How Will I Feel When I Quit Smoking?
You may crave cigarettes, be irritable, feel very hungry, cough often, get headaches, or have difficulty concentrating. These symptoms of withdrawal occur because your body is used to nicotine, the active addictive agent within cigarettes.
When withdrawal symptoms occur within the first two weeks after quitting, stay in control. Think about your reasons for quitting. Remind yourself that these are signs that your body is healing and getting used to being without cigarettes.
The withdrawal symptoms are only temporary. They are strongest when you first quit but will usually go away within 10 to 14 days. Remember that withdrawal symptoms are easier to treat than the major diseases -- like heart disease and lung cancer -- that smoking can cause.
You may still have the desire to smoke, since there are many strong associations with smoking. People may associate smoking with specific situations, with a variety of emotions or with certain people in their lives. The best way to overcome these associations is to experience them without smoking cigarettes. If you relapse do not lose hope. Seventy-five percent of those who quit smoke again. Most smokers quit three times before they are successful. If you relapse, don't give up! Plan ahead and think about what you will do next time you get the urge to smoke.
The good news is your risk of heart disease is cut in half after quitting tobacco for one year. After 15 smoke free years, your risk is similar to that of a person who has never smoked.

Examples of coronary heart disease tests include:
- electrocardiogram (ECC, EKG),
- exercise stress test,
- radionuclide stress test,

- pharmacologic stress test,
- CT coronary angiogram, and

Heart Attack Symptoms and Early Warning SignsRecognizing heart attack symptoms and signs can help save your life or that of someone you love. Some heart attack symptoms, including left arm pain and chest pain, are well known but other, more nonspecific symptoms may be associated with a heart attack.

Heart: How the Heart WorksThe heart is a very important organ in the body. It is responsible for continuously pumping oxygen and nutrient-rich blood throughout your body to sustain life. It is a fist-sized muscle that beats (expands and contracts) 100,000 times per day, pumping a total of five or six quarts of blood each minute, or about 2,000 gallons per day.
High Blood Pressure Hypertension
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

Elevated homocysteine levels (hyperhomocysteinemia) is a sign that the body isn't producing enough of the amino acid homocysteine. The condition may be genetic (inherited) called homocystinuria. Homocystinuria is a somewhat rare genetic (inherited) condition that includes symptoms like developmental delays, osteoporosis, blood clots, heart attack, heart disease, stroke, and visual abnormalities died at an early age. There are other causes of the condition like alcoholism.
Supplementing the diet with folic acid and possibly vitamins B6 and B12 supplements can lower homocysteine levels. Currently there is no direct proof that taking folic acid and B vitamins to lower homocysteine levels prevent heart attacks and strokes. Talk to your doctor if you feel you need to have your homocysteine blood levels checked.

Peripheral Vascular Disease
Peripheral vascular disease (PVD) refers to diseases of the blood vessels (arteries and veins) located outside the heart and brain. While there are many causes of peripheral vascular disease, doctors commonly use the term peripheral vascular disease to refer to peripheral artery disease (peripheral arterial disease, PAD), a condition that develops when the arteries that supply blood to the internal organs, arms, and legs become completely or partially blocked as a result of atherosclerosis. Peripheral artery disease symptoms include intermittent leg pain while walking, leg pain at rest, numbness in the legs or feet, and poor wound healing in the legs or feet.
Treatment for peripheral artery disease include lifestyle measures, medication, angioplasty, and surgery.

Stroke Symptoms and Treatment
A stroke is an interruption of the blood supply to part of the brain caused by either a blood clot (ischemic) or bleeding (hemorrhagic). Symptoms of a stroke may include
- double vision or vision loss,
- vertigo, and
- difficulty speaking or understanding speech.
A physical exam, imaging tests, neurological exam, and blood tests may be used to diagnose a stroke. Treatment may include administration of clot-busting drugs, supportive care, and in some instances, neurosurgery. The risk of stroke can be reduced by controlling high blood pressure, high cholesterol, diabetes, and stopping smoking.
