Unstable angina. People with coronary artery disease may develop unstable angina, meaning pain and discomfort can happen unpredictably, even during rest. The pain is generally more severe and frequent than that of chronic angina. New or more severe symptoms of unstable angina require medical help right away, since a heart attack may be about to happen. Chronic angina patients may develop unstable angina as their condition progresses. Syndrome X.

Some risk factors for coronary artery disease (CAD), such as your sex, age, and family history, cannot be changed. Other risk factors for CAD that are related to lifestyle often can be changed. Your chance of developing coronary artery disease increases with the number of risk factors you have. Using birth control pills and you smoke and are over age 35, or you have a family history of atherosclerosis or blood-clotting disorders.

According to the American Heart Association's 2002 Heart and Stroke Statistical Update, more than 6.6 million people in the United States are currently diagnosed with angina. Of those, 4.1 million are women and 2.5 million are men. In addition, more than 400,000 people are newly diagnosed with angina each year. Read more about who gets angina and why in Risk Factors.

Your father has a serious heart condition that occurs when the heart does not receive all the oxygen-rich blood it needs to function well. He may feel pain or discomfort in the center of the chest behind the breastbone. He may also have what is called "radiating pain" in the jaw, shoulder, back, or arms. Angina pain can be triggered by physical activity, such as climbing stairs, or by emotional stress, such as frustration or anger.

Gene therapy for angiogenesis. To grow new vessels, the body produces a protein called VEGF. A new procedure enables physicians to inject the gene for VEGF directly into the patient's heart muscle. Researchers hope the gene will become a part of the heart muscle cells and help grow new blood vessels, which will provide other pathways for oxygen-rich blood to move around clogged coronary arteries and reach the heart. Drug-coated stents.

episode of angina is NOT a heart attack. However, people with angina report having a hard time telling the difference between angina symptoms and heart attack symptoms. Angina is a recurring pain or discomfort in the chest that happens when some part of the heart does not receive enough blood temporarily. A person may notice it during exertion (such as in climbing stairs). It is usually relieved within a few minutes by resting or by taking prescribed angina medicine.

It most certainly is. Although CFS/ME and Depression do share some similar symptoms, they are completely different conditions. For one, Depression is a psychiatric condition, whereas CFS/ME is a neurological one. Depression is a very serious condition in it’s own right. And in fact, Depression can actually be a symptom of CFS/ME.

Angina means pain or discomfort, coming from the heart, generally due to blocked arteries, and usually occurring with exertion. Not all chest pain is angina, and not all people with blocked arteries have pain. Not necessarily. Only in people with certain "high-risk" characteristics (e.g. unstable symptoms, triple vessel disease, poor heart muscle function) has it been proven that we can prolong life by these methods.

Unfortunately, a simple EKG does not reliably detect angina. Therefore, the physician must perform additional tests, like an exercise stress test. The stress test is the only investigation needed for many people, since it is accurate most of the time. But even this test cannot identify exactly where or how severely the coronary arteries are blocked. So, in some people, additional tests like coronary angiography may be required.

Angina is a symptom of coronary artery disease (CAD), the most common type of heart disease. CAD occurs when plaque builds up in the coronary arteries. This buildup of plaque is called atherosclerosis. As plaque builds up, the coronary arteries become narrow and stiff. Blood flow to the heart is reduced. This decreases the oxygen supply to the heart muscle. The three types of angina are stable, unstable, and variant (Prinzmetal's). It is very important to know the differences among the types.

Comedo (whiteheads or blackheads) or papules. The comedo is the basic acne lesion, which is a plugged pore. If the plugged pore stays under the skin, it's called a closed comedo and forms a white bump or whitehead. Blackheads are comedos that open up and appear blackish on the surface of the skin. This black color is not due to dirt, but because the air reacts with the excess oil. Nodules. These are more serious acne lesions. They lodge deeper in the skin, are painful, and can cause scarring.

See Special Events for a detailed description. A "regular" orienteering meet is point to point, take the controls in order, fastest person wins. A Score-o leaves the order up to the competitor. Controls have a point value. Most points in shortest time wins. A Night-o is just like regular Orienteering, it's just in the dark, and, yes, you bring a flashlight!

Diabetic retinopathy is classified as either nonproliferative (background) or proliferative. Nonproliferative retinopathy is the early stage, where small retinal blood vessels break and leak. In proliferative retinopathy, new blood vessels grow abnormally within the retina. This new growth can cause scarring or retinal detachment, which can lead to vision loss. The new blood vessels may also grow or bleed into the vitreous humor, the transparent gel filling the eyeball in front of the retina.

composed of a main lens and two reading ssegments; one for near and one for intermediate distances (about arm lengths) high power plus lenses used for cataract patients. - made with aspheric surfaces to minimise aberrations due to shape of the lens darken when exposed to short wavelength radiation (300nm - 400nm) or ultra-violet light - rate of darkening and final transmission of the lens (saturation transmission) depends on the ambient temperature.

All types respond differently to natural hormones occurring in different amounts in both men and women. Not all hair is visible on the surface of your skin. Hair growth goes between active and resting stages. On your head, above 90% of your hair is in the active growing stage that can last up to 7 years. The growing cycle of your body hair lasts only for a few months and as much as 30% of your hair is in the resting stage.

The two most prevalent types of migraine headache are migraines with aura and migraine without aura, the latter of the two being more common.

There are many different types of kidney stones. The vast majority of stones are composed of calcium. The most common types of stones are calcium oxalate (70%), calcium phosphate (5-10%), struvite (10%), uric acid (10%) and cystine (1%). It is not uncommon for a single stone to be made of more than one of these types. When this occurs, the stone is commonly referred to as a mixed stone. Less common types of kidney stones include Xanthine, DHA and crixivan stones.
