What is angina? Stable and unstable angina - Diagnosis and treatment of angina Angina is a type of chest pain caused by reduced blood flow to the heart. Angina is a symptom of coronary artery disease Diagnosis of angina To diagnose angina, your doctor will begin by performing a physical exam and asking about your symptoms and risk factors, including a family history of heart disease. There are several tests your doctor may order to help confirm a diagnosis of angina, including: Electrocardiogram (ECG): Each heartbeat is caused by electrical signals generated by special cells in your heart. An ECG records these electrical signals as they travel through your heart. Your doctor can look for patterns between heartbeats to see if blood flow through your heart has slowed or stopped or if you're having a heart attack. Stress test: Sometimes angina is easier to diagnose when your heart is working harder. During a stress test, your doctor will walk on a treadmill or ride a stationary bike. During the exercise, your blood pressure and ECG readings will be monitored. Other tests may also be done during a stress test. If you can’t exercise, you may be given drugs that make your heart work harder to simulate exercise. Echocardiogram: Sound waves are used to create pictures of your heart. Your doctor can use these pictures to look for problems with angina, including whether areas of your heart muscle have been damaged by poor blood flow. Sometimes an echocardiogram is done during a stress test to see if areas of your heart aren’t getting enough blood. Nuclear stress test: A nuclear stress test helps measure blood flow to your heart muscle at rest and during stress. It’s similar to a regular stress test, but during a nuclear stress test, a radioactive substance is injected into your bloodstream. This substance mixes with your blood and travels to your heart. A special scanner — which detects the radioactive substance in your heart — creates pictures of your heart muscle. If the radioactive substance doesn’t show up in any area of ​​your heart, it means it’s not getting enough blood. Chest X-ray: This test takes pictures of your heart and lungs. This test is used to look for other conditions that might explain the symptoms, and to see if the heart is enlarged. Blood tests: Some heart enzymes slowly leak into the blood when the heart is damaged by a heart attack. Blood samples can be tested for these enzymes. Coronary angiography. Coronary angiography uses X-rays to examine the blood vessels of the heart. It is part of a general group of procedures known as cardiac catheterization. During a coronary angiography, a type of dye that is visible through an X-ray machine is injected into the blood vessels of the heart. The X-ray machine quickly takes a series of pictures (angiograms), providing a detailed look inside the blood vessels. Cardiac CT scan: In a cardiac CT scan, you lie on a table inside a ring-shaped machine. An X-ray tube inside the machine rotates around your body and collects images of your heart and chest, which can show if any of the heart arteries are narrowed or if the heart muscle is enlarged. Cardiac MRI: In this test, the patient lies on a table inside a long tube-like machine that produces detailed images of the structure of the heart and blood vessels. https://yasserelnahas.org/%d8%aa%d8%b...
