Question: How to diagnose Heart Disease in Women ?
Answer: Your doctor will diagnosecoronary heart disease(CHD) based on your medical and family histories, your risk factors, a physical exam, and the results from tests and procedures.
                
No single test can diagnose CHD. If your doctor thinks you have CHD, he or she may recommend one or more of the following tests.
                
EKG (Electrocardiogram)
                
An EKGis a simple, painless test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through the heart.
                
An EKG can show signs of heart damage due to CHD and signs of a previous or current heart attack.
                
Stress Testing
                
Duringstress testing,you exercise to make your heart work hard and beat fast while heart tests are done. If you can't exercise, you may be given medicines to increase your heart rate.
                
When your heart is working hard and beating fast, it needs more blood and oxygen. Plaque-narrowed coronary (heart) arteries can't supply enough oxygen-rich blood to meet your heart's needs.
                
A stress test can show possible signs and symptoms of CHD, such as:
                
Abnormal changes in your heart rate or blood pressure
                
Shortness of breath or chest pain
                
Abnormal changes in your heart rhythm or your heart's electrical activity
                
If you can't exercise for as long as what is considered normal for someone your age, your heart may not be getting enough oxygen-rich blood. However, other factors also can prevent you from exercising long enough (for example, lung diseases,anemia, or poor general fitness).
                
As part of some stress tests, pictures are taken of your heart while you exercise and while you rest. These imaging stress tests can show how well blood is flowing in your heart and how well your heart pumps blood when it beats.
                
Echocardiography
                
Echocardiography (echo) uses sound waves to create a moving picture of your heart. The test provides information about the size and shape of your heart and how well your heart chambers and valves are working.
                
Echo also can show areas of poor blood flow to the heart, areas of heart muscle that aren't contracting normally, and previous injury to the heart muscle caused by poor blood flow.
                
Chest X Ray
                
Achest x raycreates pictures of the organs and structures inside your chest, such as your heart, lungs, and blood vessels.
                
A chest x ray can reveal signs ofheart failure, as well as lung disorders and other causes of symptoms not related to CHD.
                
Blood Tests
                
Blood tests check the levels of certain fats, cholesterol, sugar, and proteins in your blood. Abnormal levels may be a sign that you're at risk for CHD. Blood tests also help detectanemia,a risk factor for CHD.
                
During a heart attack, heart muscle cells die and release proteins into the bloodstream. Blood tests can measure the amount of these proteins in the bloodstream. High levels of these proteins are a sign of a recent heart attack.
                
Coronary Angiography and Cardiac Catheterization
                
Your doctor may recommendcoronary angiography(an-jee-OG-rah-fee) if other tests or factors suggest you have CHD. This test uses dye and special x rays to look inside your coronary arteries.
                
To get the dye into your coronary arteries, your doctor will use a procedure calledcardiac catheterization(KATH-eh-ter-ih-ZA-shun).
                
A thin, flexible tube called a catheter is put into a blood vessel in your arm, groin (upper thigh), or neck. The tube is threaded into your coronary arteries, and the dye is released into your bloodstream.
                
Special x rays are taken while the dye is flowing through your coronary arteries. The dye lets your doctor study the flow of blood through your heart and blood vessels.
                
Coronary angiography detects blockages in the large coronary arteries. However, the test doesn't detectcoronary microvascular disease(MVD). This is because coronary MVD doesn't cause blockages in the large coronary arteries.
                
Even if the results of your coronary angiography are normal, you may still have chest pain or other CHD symptoms. If so, talk with your doctor about whether you might have coronary MVD.
                
Your doctor may ask you to fill out a questionnaire called the Duke Activity Status Index. This questionnaire measures how easily you can do routine tasks. It gives your doctor information about how well blood is flowing through your coronary arteries.
                
Your doctor also may recommend other tests that measure blood flow in the heart, such as acardiac MRI (magnetic resonance imaging) stress test.
                
Cardiac MRI uses radio waves, magnets, and a computer to create pictures of your heart as it beats. The test produces both still and moving pictures of your heart and major blood vessels.
                
Other tests done during cardiac catheterization can check blood flow in the heart's small arteries and the thickness of the artery walls.
                
Tests Used To Diagnose Broken Heart Syndrome
                
If your doctor thinks you have broken heart syndrome, he or she may recommend coronary angiography. Other tests are also used to diagnose this disorder, including blood tests, EKG, echo, and cardiac MRI.
