A STRESS ECHO HAS LESS FALSE NEGATIVE AND FALSE POSITIVE RESULTS ACROSS THE SPECTRUM AND IS DEFINITELY BECOMING THE TEST OF CHOICE AMONGST CARDIOLOGISTS and GP's.
Stress Echocardiogram Explained
A stress echo is a more dynamic test that examines the heart in action. It combines an ultrasound of the heart with a stress test. A stress test, often called a treadmill test, measures how your heart works when experiencing added workload or “stress” of exercise.
It assesses your heart function under stress and can show problems that are not visible when your heart is resting. Your provider may recommend an echo stress test if you have symptoms of heart disease or an existing heart condition.
The stress echo is especially useful in diagnosing coronary heart disease and the presence of blockages in the coronary arteries (the vessels that supply oxygen-rich blood to the heart muscle).
In clinical practice, exercise ECG is combined with stress Echo imaging for the evaluation of coronary artery disease. Although it is not uncommon for patients to have discordant results (abnormal ECGs and normal Echos), it was previously unclear whether this had any prognostic significance for these patients.
A coronary angiogram is a type of X-ray used to examine the coronary arteries supplying blood to your heart muscle. It's considered to be the best method of diagnosing coronary artery disease - conditions that affect the arteries surrounding the heart.
Yes! Despite the mayhem and confusion, echocardiograms are completely reliable. It's only in extreme cases that heart disease can go unnoticed. Usually, if your cardiologist finds something suspicious, you might have to take another test to clear out the doubts.
A normal stress test result only shows that there is not a significant coronary artery blockage. A smaller blockage could be present that isn't picked up by the stress test.
Stress echocardiography is a test that uses ultrasound imaging to show how well your heart muscle is working to pump blood to your body. It is most often used to detect a decrease in blood flow to the heart from narrowing in the coronary arteries.
Coronary computed tomography angiography (CTA) is the current go-to for triaging chest pain patients in the emergency department (ED), but a recent study found the often-overlooked stress echocardiography (SE) may actually be safer and provide patients with a better overall experience.
A stress test, sometimes called a treadmill stress test or exercise test, is used to find out how well your heart functions during stress but only assesses the ECG during the test unlike stress echo (see Stress Echocardiography) which looks at the heart with ultrasound as well.
The nuclear stress test is generally considered to be the most accurate type of stress test. It has a sensitivity of about 81%, meaning that it will miss about 19% of high-grade blockages.
A Nuclear Stress Test can determine with 95% accuracy if your symptoms are related to any plaque or blockages in the arteries. A Regular Stress Test has only a 65% accuracy of diagnosing patients with Coronary Artery Disease (CAD).
After your test, your doctor will go over your results with you. Normal results mean that your heart and its valves are working the right way, and the amount of blood your heart pumps out is normal.
Minor symptoms of heart blockage include irregular or skipped heartbeats, shortness of breath and chest tightness. Other symptoms may include pain or numbness in the legs or arms, as well as neck or throat pain.
Oftentimes, the next step for people who fail a stress test, and who have risk factors for or symptoms of cardiovascular disease, is an imaging test called a coronary angiography. Your doctor may call it a cardiac catheterization, or “cath” for short.
Stress tests are commonly used to diagnose coronary artery disease or an irregular heart rhythm (arrhythmia), or to help your doctor plan treatment for a heart condition you've been diagnosed with.
The test ends after maintaining your target heart rate long enough to capture readings about heart function, usually about 10 to 15 minutes. Your target heart rate is higher than when at rest and based on your age and fitness level. Technicians may end the test early if you experience severe symptoms or ask to stop.
During the test, some people feel chest pain, shortness of breath, dizziness, or a fast heartbeat. Let the person who is doing the test know right away if you don't feel well.
The Effect of Anxiety on the Heart
Rapid heart rate (tachycardia) – In serious cases, can interfere with normal heart function and increase the risk of sudden cardiac arrest. Increased blood pressure – If chronic, can lead to coronary disease, weakening of the heart muscle, and heart failure.
Echocardiograms also provide highly accurate information on heart valve function. They can be used to identify leaky or tight heart valves. While the EKG can provide clues to many of these diagnoses, the echocardiogram is considered much more accurate for heart structure and function.
Echocardiography is a type of ultrasound scan, where high-frequency sound waves are used to create an image of the heart. However, it's not always possible to detect heart defects, particularly mild ones, using foetal echocardiography.
A CT coronary angiogram can reveal plaque buildup and identify blockages in the arteries, which can lead to a heart attack. Prior to the test, a contrast dye is injected into the arm to make the arteries more visible. The test typically takes 30 minutes to complete.
