A transient ischemic attack (TIA), or mini-stroke, is often a warning sign of a future stroke - you should call paramedics right away (dial 911 in the U.S.). Blood clots, occluded arteries and leaking blood vessels caused by high blood pressure may cause TIAs. Symptoms:
- include neurologic deficits,
- speech problems,
- vision problems, and

CT ScanWhat is a CT scan? Computerized tomography scans (CT scans) are important diagnostic tools for a variety of medical conditions. Some areas of the body frequently evaluated by CT scans include the brain, neck, spine, chest, abdomen, pelvis, and sinuses. The CT scan process uses X-rays and a computer to produce cross-sectional images of the body.
Heart AttackA heart attack is an interruption in blood flow to the heart muscle. Arterial plaque rupture is often the cause of a heart attack. Symptoms of a heart attack may include chest pain, shortness of breath, sweating, and nausea. Emergency heart catheterization and thrombolytic therapy may be used to treat a heart attack.
High Blood PressureHigh blood pressure (hypertension) may be present in an individual, without any symptoms. Thus, it is called the "silent killer." Causes of high blood pressure include heart disease, kidney disease, tumors, birth control, alcohol, thyroid dysfunction, and birth control pills.Treatment of high blood pressure is generally through diet, exercise, and medication if necessary.
High CholesterolHigh cholesterol levels can lead to heart disease, stroke, angina, blood clot formation, stroke, and peripheral artery disease. Causes of high cholesterol include heredity, age, gender, stress, and lifestyle choices. Cholesterol levels can be reduced with lifestyle changes and medication if necessary (statins, fibrates, bile acid sequestrants, or niacin).
HomocysteineHomocysteine is an amino acid produced by the body, usually as a byproduct of consuming meat, fish or dairy. Elevated levels of homocysteine in the blood do not usually cause symptoms, but they raise the risk for heart disease like heart attack and stroke. The cause of high homocysteine levels is usually dietary deficiencies in vitamin B6, vitamin B12, and folic acid. Homocystinuria is a rare genetic condition in which homocysteine is excreted in the urine. Testing generally is done on the newborn if the disease runs in the family. Treatment to lower homocysteine levels is vitamin supplementation.
Cholesterol FAQsCholesterol is a waxy, fat-like substance that is naturally present in the body. Diets high in fat, inactivity, and obesity contribute to high cholesterol. Some factors such as genetics are uncontrollable for having high cholesterol. You can lower your cholesterol levels naturally with lifestyle changes such as weight loss and control, exercise, diet, and quitting smoking. If these measures don't lower cholesterol enough a person may need to take cholesterol medications.
Magnetic Resonance Imaging (MRI)Magnetic resonance imaging (MRI) is a scanner that takes cross-sectional images of the body. It is used to evaluate tissues of the head, neck, chest, limbs, abdomen, and pelvis. MRI is a very safe procedure; sedation may be used for infants, small children, or adults who are claustrophobic.
ObesityMore than two-thirds of Americans are overweight, including at least one in five children. Nearly one-third are obese. Obesity is on the rise in our society because food is abundant and physical activity is optional. The safest way to lose weight is to eat less and exercise more. Treatment may also include medications, surgery, and behavior modification.
Pulmonary EmbolismA pulmonary embolism (PE) is a blood clot in the lung. The clot typically comes from other areas of the body and travels to the lung, where it becomes lodged. Pulmonary embolism can cause serious problems, from shortness of breath to instantaneous death, depending on the nature of the clot.
