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. High risk patients with a good story for CAD should be considered for an angiogram.
Stress ECG and stress echocardiography are functional tests, they cannot state a percentage of coronary stenosis (as commonly reported in CT coronary angiography). While stress echocardiography can imply which artery may be stenosed, stress ECG does not specify which coronary artery is the culprit vessel.
An Angiography is the only test that confirms blocks in the heart. 2D Echocardiography and color doppler is the only test that can help in making a diagnosis of heart failure because heart failure diagnosis will be done depending on heart function.
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).
Stress tests were maximal in 81.37% for exercise echo and 88.34% for dobutamine echo (p = NS); the percentage of age predicted heart rate reached by exercise was 90.51% and 92.89% for dobutamine.
So the patient may have difficulty in performing; Some complications can be encountered during exercise echocardiography such as: Changes in blood pressure that can increase or decrease blood pressure, arrhythmias, angina, myocardial infarction but very rarely..
Stress echo can help diagnose or monitor the status of other conditions, such as: Cardiomyopathy. Congenital heart disease. Heart failure.
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.
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.
CT angiography is a less invasive version of the traditional angiogram. The main difference between the two procedures is that while a standard angiogram involves a catheter being inserted into the artery and to the area being studied, a CT angiogram does not require the insertion of a catheter.
Your doctor may recommend that you have a coronary angiogram if you have: Symptoms of coronary artery disease, such as chest pain (angina) Pain in your chest, jaw, neck or arm that can't be explained by other tests. New or increasing chest pain (unstable angina)
An echocardiogram can help diagnose and monitor certain heart conditions by checking the structure of the heart and surrounding blood vessels, analysing how blood flows through them, and assessing the pumping chambers of the heart.
In addition to failed stress tests, your doctor may recommend one if you have chest pain, also called angina. Because chest pain can have many causes, a coronary angiogram is used to see if your heart and arteries are the source of the pain.
Currently, the angiogram is the most accurate diagnostic test for a range of heart problems, including coronary heart disease.
While LVEF in the range of 40% to 55% is abnormal, it often has little clinical significance. 6. In moderate or severe mitral regurgitation, however, even a nominally “normal” LVEF of 60% can indicate inadequate LV performance.
The most common type of heart defect is a ventricular septal defect (VSD).
While an echocardiogram looks at the structure of your heart, an electrocardiogram measures the electrical activity of your heart, or the impulses that cause your heart to beat, contract, and push blood out to your body.
Echo Stress Test
In this ultrasound test, also known as an echocardiogram, sound waves are used to create images of the heart. It can reveal how well the heart is pumping blood. Your doctor can identify any areas where blood isn't flowing properly.
Statins help lower low-density lipoprotein (LDL) cholesterol, also known as “bad” cholesterol, in the blood. They draw cholesterol out of plaque and stabilize plaque, Blaha says.
If your results come back as normal, it means you likely do not have severe coronary artery blockage (70% blockage or greater). However, stress echo tests only reveal severe narrowing of arteries. Heart attacks can happen from less severe blockages.
Advantages of stress echocardiography include its ready availability, relatively low capital cost, and incremental value in that it allows characterization of cardiac anatomy as well as the myocardial response to a potentially ischemic stimulus.
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.
