what is angiogram and how to prevent heart attack?

Answer 1

Angiogram
From Wikipedia, the free encyclopedia

Angiography or arteriography is a medical imaging technique in which an X-ray picture is taken to visualize the inner opening of blood filled structures, including arteries, veins and the heart chambers. Its name comes from the Greek words angeion, "vessel", and graphien, "to write or record". The X-ray film or image of the blood vessels is called an angiograph, or more commonly, an angiogram.

The Portuguese physician and neurologist Egas Moniz, Nobel Prize winner in 1949, developed in 1927 the technique of contrasted x-ray cerebral angiography to diagnose several kinds of nervous diseases, such as tumors and arteriovenous malformations. He is usually recognised as one of the pioneers in this field. With the introduction of the Seldinger technique in 1953, the procedure became markedly safer as no sharp introductory devices needed to remain inside the vascular lumen.

Angiograms require the insertion of a catheter into a peripheral artery, e.g. the femoral artery.

As blood has the same radiodensity as the surrounding tissues, a radiocontrast agent (which absorbs X-rays) is added to the blood to make angiography visualization possible. The angiographic X-Ray image is actually a shadow picture of the openings within the cardiovascular structures carrying blood (actually the radiocontrast agent within). The blood vessels or heart chambers themselves remain largely to totally invisible on the X-Ray image.

The X-ray images may be taken as either still images, displayed on a fluoroscope or film, useful for mapping an area. Alternatively, they may be motion images, usually taken at 30 frames per second, which also show the speed of blood (actually the speed of radiocontrast within the blood) traveling within the blood vessel.

The most common angiogram performed is to visualize the blood in the coronary arteries. A long, thin, flexible tube called a catheter is used so as to administer the radiocontrast agent at the desired area to be visualized. The catheter is threaded into an artery in the groin or forearm, and the tip is advanced through the arterial system into one of the two major coronary arteries. X-ray images of the transient radiocontrast distribution within the blood flowing within the coronary arteries allows visualization of the size of the artery openings. Presence or absence of atherosclerosis or atheroma within the walls of the arteries cannot be clearly determined. See coronary catheterization for more detail.

Angiography is also commonly performed to identify vessel narrowing in patients with retinal vascular disorders, such as diabetic retinopathy and macular degeneration.

How to Prevent a Heart Attack

Heart attacks are the number one killer of American women, yet sixty four percent of those who die are asymptomatic. LHJ provides lifesaving tools to help assess your risk.


Visit Your Physician – An appointment with your internist or family doctor will help determine whether you are at low, moderate or high risk of heart disease based on multiple factors including family and personal medical history, lifestyle, symptoms, blood pressure, body mass index, waist-to-hip ration, basic tests.


High Risk – If your checkup reveals heart disease symptoms or you require further testing, you will be referred to a cardiologist who will run various tests based on your condition: resting echocardiogram/stress echocardiogram, calcium, MRI, angiogram.


Moderate Risk – Red flags raised in your doctor’s visit suggest you should make diet and exercise changes as well as reducing stress and eliminating smoking. Depending on your prognosis, you may be prescribed statins or niacin to lower LDL levels and raise HDL.


Low Risk – Keep it up. Find out how often you require follow-ups and how to stay healthy as you age.


Plus- Six steps to the Best Heart-Health Checkup.


Thorough Medical and Family History – Provide a detailed account of your medical and family history. Having a mother or sister who developed heart disease before age 65 or a father or brother with the disease before 55 increases your odds as does having a hysterectomy, experiencing early-onset menopause and diabetes. Lifestyle habits can also affect your risk, be sure to mention if you smoke, how often you exercise, how healthy your diet is and whether you are stressed.


Frank About Symptoms – Early signs of a heart attack in women can be more subtle than men’s: fatigue, back pain, shortness of breath, severe heartburn, chills, nausea, numbness in one or both arms, heart palpitations.


Basic Measurements – Routine physical exams include blood pressure monitoring (anything higher that 120/80) is risky,) BMI (ratio of weight and height) and waist-to-hip ratio (waist measurement divided by hip measurement), a better heart attack predictor than BMI.



Must-Do Tests – Be sure to ask for these tests: a fasting lipid profile test to measure levels of three blood fats including LDL (bad cholesterol forms plaque that attaches to blood vessel walls), triglycerides (transport fatty acids into your blood) and HDL (good cholesterol.) A fasting blood glucose test reveals your diabetes risk, a major heart disease contributor. A resting ECG, or electrocardiogram, if the last must-have test, especially for women over 40.


Additional Scans – If you have heart disease risk factors, you may also have a C-reactive protein test and an LDL Particle Size Test.


Maintain Your Health –Once your risk factor level has been determined, work with your doctor to determine your next course of action.

Answer 4

An angiogram is done by injecting dye into the vessels around your heart so that doctors can see whether and where you have blockages. A "line" is threaded through your vein (maybe artery, I'm not sure, but a search online would clear that up) in the groin area and it goes up toward your heart. Dye is sent through the line, and doctors can see what's going on. The patient has anesthesia. This procedure, I believe, may have a small risk of heart attack occurring as a result of it. A person who needs the procedure has to probably consider what will happen if the doctor can't figure out what's going on, and that the risk is low, and if something were to go on the doctor would be right there to address any sudden problem.

Preventing a heart attack in general?

Eat right, get exercise that's right for you, don't smoke, keep your blood pressure down, keep your cholesterol down, try to control stress as much as possible, try to make time to relax, see a doctor for check-ups in order to head off any problems before they can cause a heart attack.

Answer 5

Angiogram, using dye in the cardiac arteries, which they won't do without strong symptoms of chest pain related to the heart. Thallium scan that tries to view arteries through the chest. Stress tests can be inaccurate for people with good collateral circulation. Mine is good, and a stress test 9 months before angina showed up gave no hint I would have 99% occluded coronary arteries and nearly die. If you are that worried, change your diet and lifestyle as if you were diagnosed with heart disease. You can head it off, level out, or possibly reverse current damage a little at a time. I have four siblings, same age or older. I am the only one with a heart problem, severe blockages, for which I had a triple bypass. It is partly genetic, but also depends on diet, stress, and lifestyle.

Answer 6

Radiography of vessels after the injection of a radiopaque contrast material; usually requires percutaneous insertion of a radiopaque catheter and positioning under fluoroscopic control. See Also: arteriography, venography.

Answer 7

aniogram menas imaging your blood vessels after injecting special dye.

heart attacks could be prevented by diet , exerices and lowering cholesterol, stopping smoking.
Also it is helpful to be young and have good genetics
