The imaging is necessary because stress changes from drugs may not be detectable by ECG alone. A cardiologist interprets heart stress tests results. Your doctor will review them with you. Here’s a summary of the information doctors use in their interpretation and what their conclusions could mean.
For safety reasons, a cardiac stress test would not be used if you have any of the following conditions: Unstable angina not yet stabilized with medication Severe pulmonary hypertension Uncontrolled arrhythmia Inadequately controlled congestive heart failure Pulmonary embolism (a clot in the arteries of a lung)
In terms of accuracy, a cardiac stress test is often open to interpretation, and results can vary based on the equipment used, the experience of the technician, and other factors that can change from day to day (such as whether a characteristic symptom occur during the test or not).
While a cardiac stress test may leave you momentarily winded, it shouldn’t interfere with your ability to drive home. With that being said, if you are older and/or unaccustomed to exercise or experience frequent lightheadedness, angina, or acute respiratory symptoms, you may want to bring a driving companion just in case. 21
You are usually notified of the results within 24 hours. If the test is normal, your family doctor will advise follow-up care to determine what else may be causing your discomforts.
After a stress test Your doctor can watch for any problems as your heart rate and breathing return to normal. When your exercise stress test is complete, you may return to your normal activities unless your doctor tells you otherwise.
After a stress test indicates an abnormality, heart specialists turn to a more invasive but also much more informative test, a heart catheterization with angiography. A long, thin tube called a catheter is threaded through blood vessels to the heart. Using a special dye, doctors can see the blockages precisely.
A primary reason why a stress test is performed is to assess the patient's blood and oxygen flow to their heart. A stress test can potentially diagnose medical conditions like coronary artery disease. During a stress test, a patient may have an irregular heartbeat or their heart rate might speed up or slow down.
The test takes about one hour, including prep time and actual test time. The cardiac stress test itself only lasts around 15 minutes. During your test, you may walk on a treadmill or pedal a stationary bicycle.
“Most people think a stress test identifies blockages to the heart, but it does not,” explains Aristotelis Vlahos, M.D., director of the Cardiac Catheterization Lab at Riverview Medical Center. “It looks at blood flow to the heart muscle and determines if blood flow is adequate or not.
The nuclear stress test also provides information about overall heart function, however doesn't provide information about the heart valves or lining around the heart (pericardium) the way an echo does. An echo or nuclear stress test may not reveal certain conditions, such as microvascular angina.
Possible ConclusionsPositive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemia—meaning the heart muscle wasn't getting adequate oxygenated blood during the stress. ... Negative or normal: A negative test result lacks any of the things that could trigger a positive conclusion.More items...
Additionally, some manifestations of anxiety disorders can lead to abnormal ECG readings. When false positives occur for rhythm irregularities or other concerns, preexisting anxiety or even test-invoked nervousness may be factors.
You are also given medicine (local anesthetic) to numb your throat. This helps you feel more comfortable during the procedure. An exercise stress test measures how your heart deals with the stress of physical activity.
Because exercise makes your heart pump harder and faster, an exercise stress test can reveal problems with blood flow within your heart. A stress test usually involves walking on a treadmill or riding a stationary bike while your heart rhythm, blood pressure and breathing are monitored. Or you'll receive a drug that mimics the effects of exercise.
Diagnose heart rhythm problems (arrhythmias). Heart arrhythmias occur when the electrical signals that coordinate your heartbeat don't work properly. An arrhythmia can cause your heart to beat too fast, too slowly or irregularly.
Exercise stress test. Exercise stress test. In an exercise stress test, electrodes are taped to your chest to detect your heart's rhythm. A nurse or technician will watch your heartbeat on a monitor while you exercise.
Guide treatment of heart disorders. If you've already been diagnosed with a heart condition, an exercise stress test can help your doctor determine if your current treatment is working. The test results also help your doctor decide on the best treatment for you. Check your heart before surgery.
Your doctor may recommend a stress test if you have signs or symptoms of coronary artery disease or an abnormal heart rhythm (arrhythmia). A stress test can help: Guide treatment decisions. Determine how well heart treatment is working. Diagnose the severity of an existing heart condition.
A stress test usually takes about an hour, including both prep time and the time it takes to do the actual test. The actual exercise test takes only around 15 minutes.
Your coronary arteries are the major blood vessels that supply your heart with blood, oxygen and nutrients. Coronary artery disease develops when these arteries become damaged or diseased — usually due to a buildup of deposits containing cholesterol and other substances (plaques).
For a stress echocardiogram, your care team will take pictures of your heart using sound waves before and during exercise. Your provider will watch your EKG and vital signs closely throughout the stress test and will stop the test if abnormalities occur.
Any medical procedure involves risks and potential complications. Complications may become serious in some cases. A stress test carries a small risk of complications including:
Your stress test will be performed in a hospital or specialized clinic. The test takes about 30 minutes and generally includes these steps:
You are an important member of your own healthcare team. The steps you take before your stress test can help your care team obtain the most accurate results. You can best prepare for your stress test by:
Doctors use stress tests to diagnose and monitor coronary artery disease, cardiac ischemia (not enough blood flow to the heart muscle), cardiac arrhythmias (abnormal heartbeats), and other types of heart disease. A stress test is only one method to monitor and diagnose heart conditions. Discuss all of your testing options with your doctor ...
Doctors use stress tests to help diagnose or monitor the following conditions: Cardiac arrhythmias including heartbeats that are too fast , too slow, or irregular, especially arrhythmias that occur during exercise. Cardiomyopathy, thickened or enlarged heart muscle. Congenital heart defects, birth defects of the heart.
Nuclear stress test involves using an IV radioactive dye and taking pictures of your heart during a stress test. Nuclear stress tests include a thallium stress test, sestamibi (Cardiolite) stress test, and PET (positron emission tomography) stress test. Stress echocardiogram uses sound waves to take moving pictures of your heart during ...
REASON FOR STUDY: Cardiolite adenosine stress testing was performed for evaluation of chest pain and risk stratification.
EKG is basically within normal limit. EKG was recorded every 2 minutes, both during infusion of adenosine and post infusion. No ischemic ST depression or elevation was noted. The patient reported symptom of pressure feeling in the chest, which subsided after the adenosine was infused.
After the infusion of adenosine, the patient became markedly short of breath, requiring intravenous aminophylline and nebulizer treatment. The patient was taken to the emergency room for breathing treatment and further management. The test was completed without any major complications. The patient was taken to nuclear medicine for acquisition of perfusion images, which are interpreted separately by the radiologist.
REASON FOR STUDY: Cardiolite stress testing was performed for evaluation of chest pain.
FINDINGS OF STUDY: The resting heart rate was 72 beats per minute. The patient attained a maximal heart rate of 186 beats per minute which is greater than 100% of the predicted maximal heart rate. Resting blood pressure was 130/90, and at peak exercise, the blood pressure was 150/82, which is normal blood pressure response to exercise.
Resting EKG showed normal sinus rhythm, normal axis. EKG is basically within normal limits. EKG was recorded every one minute, both during infusion of adenosine and post infusion. No ischemic ST depression or elevation was noted. One PVC was noted after infusion of adenosine. Once the patient was treated with nebulizer treatment and intravenous aminophylline, his breathing improved.
REASON FOR TERMINATING THE TEST: The patient stopped secondary to leg fatigue. The patient denied chest pain.
The CT scan lasts about 15 minutes, during which time images of the heart and surrounding vasculature (arteries, veins, aorta) are taken. The dye contrasts with body tissue in the images and allows the cardiologist to determine if major blockages are evident in any of the vessels. The stress test is a repeat performance of the resting test, ...
What’s important to know is that the images will only show blockages between 50 and 70% or greater. If your results don’t show that level of obstruction, that does not mean you are free and clear of cardiovascular disease. Rather, it means that you do not have blockages that require immediate action, possibly surgery.
After the stress test, your cardiologist may or may not opt to have you undergo another type of CT test called a Calcium-score Screening Heart Scan . This test is a rather major advance in heart diagnostics. In the past, if someone passed a stress test they were sent home with a hearty assurance that they were fine. We now know that just isn’t so. Bill Clinton had multiple stress tests, all of which came back negative, not long before he had quadruple bypass surgery.
The first test I underwent was an EKG (electrocardiogram), which has been the front line test of cardiac diagnostics for many years. It’s still an excellent test for detecting heart-function irregularities by tracking the electrical activity of the heart (which is translated into a line that spikes and dips across the EKG monitor). But it can’t delve deeper into what is causing the irregularities. If something odd shows up, your doctor will likely refer you to a cardiologist for further testing.
If something odd shows up, your doctor will likely refer you to a cardiologist for further testing. Cardiologists have several diagnostic tools available to investigate what’s going on in your heart and vasculature, and the first one you’ll probably experience is a stress test. In my case, I was slated for a nuclear dye test, ...
As an example, Tim Russert was given a calcium score of 210 when he was 48 years old. He died of a major heart attack 10 years later. The calcium score was the first test that indicated he was at risk, and unfortunately he wasn’t able to outrun it.
If you are unable to do the treadmill test, the technician will instead inject you with a chemical that will elevate your heart rate without physical exertion. This is commonly done for elderly patients.
Exercise stress tests are the most common type. Doctors use chemical stress tests with medicines when people aren’t able to exercise. The standard test is an ECG—or electrocardiogram—stress test. An ECG stress test monitors your heart’s electrical activity during exercise. Medical staff will also monitor your blood pressure and breathing.
The imaging is necessary because stress changes from drugs may not be detectable by ECG alone. A cardiologist interprets heart stress tests results. Your doctor will review them with you. Here’s a summary of the information doctors use in their interpretation and what their conclusions could mean.
Imaging data: If imaging was part of the stress test, doctors will include this data. The main focus is perfusion—or the presence of adequate blood flow. They will look for areas with poor blood flow and note their size and location. Decreased or absent blood flow can indicate blockages or heart muscle damage or death.
Doctor’s look for any abnormalities that show up without any stress .
Cardiac stress tests look at how your heart reacts to the stress of an increased workload. There are several types of cardiac stress tests. But basically, the stress can come from two different stimuli—exercise or medicines. Exercise stress tests are the most common type. Doctors use chemical stress tests with medicines when people aren’t able ...
ECG changes: There are specific changes in the heart’s activity that can tell doctors about your heart health. When they are present during stress, it may mean your heart muscle isn’t getting enough oxygenated blood. Presence of arrhythmias: Changes in heart rhythm may or may not mean anything.
Other reasons may include reaching the target heart rate or having ECG changes.
Reviewing incidents helps administrators know what risk factors need to be corrected within their facilities , reducing the chance of similar incidents in the future.
Staff did not consider 62 per cent of incidents as reportable, due to unclear incident reporting requirements. Because of this, the first step to incident management in any healthcare facility is writing strong, clear reporting requirements. Then, staff can submit reports that help correct problems of all types.
Using resolved patient incident reports to train new staff helps prepare them for real situations that could occur in the facility. Similarly, current staff can review old reports to learn from their own or others’ mistakes and keep more incidents from occurring. Legal evidence.
Every facility has different needs, but your incident report form could include: 1 Date, time and location of the incident 2 Name and address of the facility where the incident occurred 3 Names of the patient and any other affected individuals 4 Names and roles of witnesses 5 Incident type and details, written in a chronological format 6 Details and total cost of injury and/or damage 7 Name of doctor who was notified 8 Suggestions for corrective action
Patient incident reports should be completed no more than 24 to 48 hours after the incident occurred.
Even if an incident seems minor or didn’t result in any harm, it is still important to document it. Whether a patient has an allergic reaction to a medication or a visitor trips over an electrical cord, these incidents provide insight into how your facility can provide a better, safer environment.
A no-harm incident means that something happened to a patient or another person but no discernible injury or illness resulted. For example, a patient could be given a blood transfusion meant for another patient but no harm was done because the blood was compatible.
Ultimately, it is the responsibility of hospitals, laboratories, radiology facilities and specialists to ensure that family physicians receive results and information pertaining to their patients in a timely manner , she said.
If, as you point out, the test results go missing, you have no way of knowing and may assume [wrongly] that there was a negative finding and all was well. It is for that reason, it is important to ensure that the loop has been closed on every test result.
In addition, patients can request the specialist’s office, hospital or laboratory to forward the results to their family physician prior to their appointment. Ideally, this should not be necessary, points out Dr. Charles, who said efforts are underway at her hospital to improve accountability for timely communication of information to family physicians.
I, too, am particularly concerned about your missing test results and for that reason I would suggest you contact your family physician to follow up. That may also be a good time to discuss how you are able to learn of test results with abnormal findings. I would also follow the advice of Dr. Charles and to call ahead of your appointment to ensure test results have been received and to request the specialist, hospital or laboratory fax or send these results to your family doctor.
As the family physician has no way of knowing what tests were done by the specialist unless this was communicated to them, Dr. Charles suggested patients call their family physician before their appointment to ensure test results have been received.
This is because test results are used to determine whether further treatment is necessary.
If your test results have been withheld from you, you may be entitled to legal relief. This could include monetary damages for any injuries resulting from the failure to communicate. You may also be able to obtain compensation for medical fees and other related costs stemming from the failure to communicate.
An attorney can help specify your course of action if you have been injured as a result of your doctor’s errors. Also, a lawyer can recommend alternative legal actions that might be appropriate for your claim.
These records and receipts may be useful in reminding yourself and others what tests have been performed on you and what test results you are currently entitled to receiving.
Another way you can ensure that you remained informed of your medical test results is to make notes on your calendar of when medical test results should be released and communicated. If you have not heard from your doctor on that date, follow up and make sure that they are up to date on your treatment.
Additionally , you may be able to file a medical malpractice lawsuit if your injury is particularly serious. You will have to prove in court that you received actual injuries as a result of the doctor’s failure to communicate test results. Also, you will need to prove that the failure to communicate test results is directly traceable to your doctor.
As the patient, you are entitled to know the results of your medical exams. All medical professionals are held to a high standard of medical care, and that standard of care includes informing the patient of the outcome of any medical test or examination, such as a colonoscopy or a mammogram, that is performed on them. Your doctor should also inform you of the purpose of the medical exam, and also of any dangers or side effects that might result from the exam.
