What is the best test to check for heart problems

Your heart is one of the hardest working organs in the body – beating once per second or about 3 billion times in the average person’s lifetime. “Seeing” it in action is an essential part of evaluating, diagnosing, and treating potential cardiovascular conditions. At UT Southwestern, we use an evolving suite of sophisticated Because the heart is also a highly complex organ, we can use different imaging tools to assess its many functions. For instance: • An electrocardiogram (EKG) records electrical signals in your heart. • A stress test assesses blood flow to the heart muscle during rest and exercise. • An echocardiogram uses ultrasound waves to create moving pictures of your heart’s chambers, valves, and walls. Our team also utilizes advanced imaging techniques, such as cardiac CT and cardiac MRI to create detailed, cross-sectional views of the heart and help diagnose complex or rare disorders. With so many options available, and new imaging enhancements in development, patients can feel overwhelmed by “all the tests.” So, we thought it would be helpful to provide a quick overview of cardiac imaging, from the fundamental to the highly specialized, and explain how each test can help our patients avoid or overcome heart disease. The choice of test is individualized, of course. Your doctor will recommend which tests, if any, are right for you based on your current health and symptoms.

Researchers are developing new ways to check your heart health. Two tests are available now; an interesting third is on the horizon. Corus CAD test (or CardioDx) This Who should have it? In research studies, people with Pros: Some insurers will cover the cost. All it takes is a small Cons: If your insurer doesn't cover the cost, it may set you back about $1,200. Hemoglobin A1c This blood test for The A1c is a measure of blood sugar levels over the last 3 to 4 months. An A1c around or below 7% has been shown to lessen the complications of diabetes that can damage Who should get it? People with diabetes. The test should be done two times a year if your Pros: You can get this done as a routine blood test. Unlike the oral glucose tolerance test, another common diabetes test, you don't have to fast beforehand or make a special trip to the lab. Cons: Some studies show the A1c test may not work well in all cases. Plaque Scan (Carotid Intima-Media Thickness Testing, or CIMT) This test is similar to a carotid "An increase in the thickness of the lining indicates the patient is at higher cardiovascular risk, even if no … plaque is present," says Mark F. Sasse, MD. He's an associate professor of cardiovascular medicine at the University of Alabama at Birmingham School of Medicine. Who should get it? "The plaque scan is a very new technology," says Sasse. "I suspect it is many years away from it being used in the clinical arena." Tests like this are typically for patients with medium ...

Your blood may offer many clues about your heart health. For example, high levels of "bad" cholesterol in your blood can be a sign that you're at increased risk of having a heart attack. And other substances in your blood can help your health care provider determine if you have heart failure or are at risk of developing fatty deposits (plaques) in your arteries (atherosclerosis). A cholesterol test, also called a lipid panel or lipid profile, measures the fats in the blood. The measurements can help determine the risk of having a heart attack or other heart disease. The test typically includes measurements of: • Total cholesterol. This is the amount of the blood's cholesterol content. A high level can increase the risk of heart disease. Ideally, the total cholesterol level should be below 200 milligrams per deciliter (mg/dL) or 5.2 millimoles per liter (mmol/L). • Low-density lipoprotein (LDL) cholesterol. This is sometimes called the "bad" cholesterol. Too much LDL cholesterol in the blood causes plaque to buildup in the arteries, which reduces blood flow. These plaque deposits sometimes rupture and lead to major heart and blood vessel problems. The LDL cholesterol level should be less than 130 mg/dL (3.4 mmol/L). Desirable levels are under 100 mg/dL (2.6 mmol/L), especially if you have diabetes or a history of heart attack, a heart stent, heart bypass surgery, or other heart or vascular condition. In people with the highest risk of heart attacks, the recommended LDL leve...

Certain elements in your blood, like your cholesterol, triglycerides, or fibrinogen, are like a window to your heart health. Using blood tests to understand your risk of coronary artery disease is a proactive approach to a healthier heart. Work with your healthcare provider to understand your results and determine the best next steps. Overview How are blood tests used to determine the risk of heart disease? Your healthcare provider may order blood and urine lab tests to determine your risk of heart and blood vessel disease. Certain results, like high levels of low-density lipoprotein (LDL), indicate a higher risk of heart disease. The test results and your health history help your healthcare team create the best care plan for you. When would I need blood tests to determine heart disease risk? Your healthcare provider may recommend • Eat an unhealthy diet. • Have a family history of CAD (especially getting diagnosed at age 50 or younger). • Have obesity or excess weight. • Don’t get enough physical activity. • • Have other comorbidities or conditions such as diabetes, high blood pressure, prior heart attack or stroke. Who performs the blood tests? A healthcare professional called a What parts of the blood do the tests measure to find heart disease risk? When detecting heart disease risk, healthcare providers pay close attention to: • Total cholesterol (TC): Your total cholesterol is directly linked to your heart and • Triglycerides (TG): • High-density lipoprotein (HDL): Th...

Cardiac blood tests can give your provider insight into how well your heart is functioning. Combining this information with your medical history and your family history can help your provider determine your risk of cardiovascular disease. Some tests, like the ones that measure cholesterol, are common. Others are not as well-known. Overview What are cardiac blood tests? Cardiac blood tests help your healthcare provider determine your risk of getting heart and blood vessel diseases. Your provider will consider your test results and look at your There are a number of different Cholesterol-related tests • Total • • High-density lipoprotein (HDL or the “good” cholesterol), which eliminates bad cholesterol. • Low-density lipoprotein (LDL or the “bad” cholesterol), which can build up in arteries. Protein-related tests • Lipoprotein (a), an additional lipoprotein that is present in some people and increased heart risk. • Apolipoprotein B (ApoB), a protein that is included in bad cholesterol. • Fibrinogen, a protein in your blood that helps it clot. • Aminoterminal, pro-brain natriuretic peptide (NT-proBNP), a protein your heart makes which is increased in heart failure. Indicators of inflammation, which may play a role in forming plaque • Ultra-sensitive C-reactive protein (us-CRP). • MPO (myeloperoxidase).

Diagnosis Your health care provider will examine you and ask about your personal and family medical history. Many different tests are used to diagnose heart disease. Besides blood tests and a chest X-ray, tests to diagnose heart disease can include: • Electrocardiogram (ECG or EKG). An ECG is a quick and painless test that records the electrical signals in the heart. It can tell if the heart is beating too fast or too slowly. • Holter monitoring. A Holter monitor is a portable ECG device that's worn for a day or more to record the heart's activity during daily activities. This test can detect irregular heartbeats that aren't found during a regular ECG exam. • Echocardiogram. This noninvasive exam uses sound waves to create detailed images of the heart in motion. It shows how blood moves through the heart and heart valves. An echocardiogram can help determine if a valve is narrowed or leaking. • Exercise tests or stress tests. These tests often involve walking on a treadmill or riding a stationary bike while the heart is monitored. Exercise tests help reveal how the heart responds to physical activity and whether heart disease symptoms occur during exercise. If you can't exercise, you might be given medications. • Cardiac catheterization. This test can show blockages in the heart arteries. A long, thin flexible tube (catheter) is inserted in a blood vessel, usually in the groin or wrist, and guided to the heart. Dye flows through the catheter to arteries in the heart. The d...

Tashi-Delek / iStock Overall Heart Health The tests below are commonly used as a general screening for heart disease and to measure overall heart health. They are typically used to establish a baseline in people with no known cardiac disease. Over time—sometimes weeks, sometimes years—the tests can be repeated to see if there is any deterioration or improvement from the baseline function. • Holter monitoring: Also known as event monitoring, this is a small portable ECG device that can be worn by the patient to monitor the heartbeat for 24 to 48 hours. • Electrophysiology study: Also known as an EP study, this is a minimally invasive procedure in which a catheter is fed into an artery to evaluate the electrical system of the heart using two large magnetics placed to either side of the patient. • •
