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.

movies, museums, shops, or libraries.

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.

Angina SymptomsAngina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.
Atrial fibrillation (AF or AFib) is an abnormality in the heart rhythm which involves irregular and often rapid beating of the heart. Symptoms may include heart palpitations, dizziness, fainting, fatigue, shortness of breath, and chest pain.
Atrial fibrillation treatment may include medication or procedures like cardioversion or ablation to normalize the heart rate.
Coronary Artery Disease Screening Tests (CAD)
Coronary heart disease or coronary heart disease (CAD) screening tests can be used to potentially prevent a heart attack or cardiac event in a person without heart disease symptoms, and can assist in diagnosing heart disease in individuals with heart disease symptoms. Examples of coronary heart disease tests include:
- electrocardiogram (ECC, EKG),
- exercise stress test,
- radionuclide stress test,
- stress echocardiography,
- pharmacologic stress test,
- CT coronary angiogram, and
- coronary angiogram.
Gum DiseaseGum disease is caused by plaque and may result in tooth loss without proper treatment.

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 in the blood called hyperhomocysteinemia, is a sign that the body isn't producing enough of the amino acid homocysteine. is a rare and serious condition that may be inherited (genetic). People with homocystinuria die at an early age. Symptoms of hyperhomocysteinemia include developmental delays, osteoporosis, blood clots, heart attack, heart disease, stroke, and visual abnormalities.
There are other causes of hyperhomocysteinemia, for example, 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 lower homocysteine levels and prevent heart attacks and strokes. Talk to your doctor if you feel you need to have your homocysteine blood levels checked.

Triglyceride TestTriglycerides are a common form of fat that we digest. Triglycerides are the main ingredient in animal fats and vegetable oils. Elevated levels of triglycerides are a risk factor for heart disease, heart attack, stroke, fatty liver disease, and pancreatitis. Elevated levels of triglycerides are also associated with diseases like diabetes, kidney disease, and medications (for example, diuretics, birth control pills, and beta blockers). Dietary changes, and medication if necessary can help lower triglyceride blood levels.
