How Do Transgender People Fit In
At the time of publication, no studies could be found that spoke to stress test results among the transgender and gender nonconforming population.
As a trans person, your expected results will depend on whether or not youve chosen to pursue hormone replacement therapy as well as a variety of other factors. Talk with a doctor if youre concerned about the results of your stress test.
How Will I Feel After My Stress Test
Most people return to normal activities after a stress test. You should not feel ill or have any symptoms after your test. Tell your doctor immediately if you experience symptoms such as dizziness, chest pain, or shortness of breath.
For a nuclear stress test, you will need to drink extra fluids to help flush the dye out of your body.

What Are The Different Types Of Stress Tests
There are many methods for assessing heart function while its hard at work. All cardiac stress tests involve checking your heart rate, blood pressure, oxygen levels and electrical activity. But there are some differences.
Stress test types include:
Exercise stress test
This is the most common and basic heart stress test. It involves walking on a treadmill or riding a stationary bicycle. A well-trained exercise physiologist usually tailors the speed and elevation of the treadmill to your ability to walk and your overall fitness.
If you cant exercise, you receive medications that make your heart pump harder and faster or dilate the artery supplying blood to your heart . An electrocardiogram captures your hearts electrical activity. Exercise stress tests check for signs of coronary artery disease.
Exercise stress echocardiogram
An exercise stress echocardiogram is similar to the basic stress test but provides more detail. Healthcare providers perform an echocardiogram before and at peak exercise. This cardiac imaging test uses sound waves to evaluate blood flow through your heart as well as the pumping chambers of your heart and valve functions.
You might need a stress echocardiogram if the results of your initial stress test are unclear. This study enables healthcare providers to observe blood flow through the hearts chambers as well as the effects of exercise.
Nuclear stress test
Nuclear cardiac stress tests can:

How To Prepare For An Exercise Stress Test
Prior to your test, your doctor will perform a physical exam and ask about your complete medical history. At this point, tell your doctor about your symptoms, especially any chest pains or shortness of breath.
You should also tell your doctor about any conditions or symptoms that may make exercising difficult, such as stiff joints from arthritis.
Finally, let your doctor know if you have diabetes, because exercise affects blood sugar. If you do have diabetes, your doctor may want to monitor your blood glucose levels during the exercise test as well.
Your doctor will give you complete instructions about how to prepare.

Why Do An Exercise Stress Test
An exercise stress test is primarily used to help your doctor determine if your heart receives enough oxygen and proper blood flow when it needs it most, such as when you are exercising.
It can be ordered for people who have been experiencing chest pains or other symptoms of coronary heart disease .
An exercise stress test may also be used to help determine your level of health, especially if you are starting a new exercise program. This allows your doctor to learn what level of exercise you can safely handle.
If you are a smoker over 40 years old, or if you have other risk factors for heart disease, you should talk to your doctor to see if an exercise stress test is right for you.
Stress tests are generally considered safe, especially since theyre done in a controlled environment under the supervision of a trained medical professional.
However, there are some rare risks, such as:
However, your risk of experiencing these reactions during the test is low, since your doctor will screen you for problems beforehand. People who are at higher risk of these complications such as those with advanced coronary heart disease are rarely asked to do the test.
What To Expect During Your Stress Test
Dr. Patel may order a stress test if you have risk factors for CAD or symptoms of a heart problem. Its a simple noninvasive test that gives our team valuable information about the state of your heart.
On the day of your stress test, our team attaches electrodes to your body and places a blood pressure cuff on your arm. You walk on a treadmill or ride a stationary bike until your heart rate reaches a predetermined target. We monitor your vital signs and how youre feeling, then you stop exercising and we remove the monitors.
Once your results are ready, Dr. Patel reviews his findings with you. If he identifies heart disease, starting a treatment plan can help manage your symptoms and reduce your risk of complications.
Our Heart Smart Program gives you the education and tools you need to make heart-healthy changes in your life. We work with you to monitor your health, and we may recommend future stress tests to track changes over time.
A stress test tells Dr. Patel how well your heart works under pressure, and whether a serious condition could be threatening your health.

What Is Target Heart Rate
Your target heart rate is a range of numbers that reflect how fast your heart should be beating when you exercise. A higher heart rate is a good thing that leads to greater fitness, says Johns Hopkins cardiologist Michael Blaha, M.D., M.P.H. During exercise, you can monitor heart rate and try to reach this target zone. Doctors also use target heart rate to interpret the results of a cardiac stress test.

Why It Is Done
Exercise stress tests are done for a variety of reasons. The most common one is to detect a narrowing or blockage in one or more coronary arteries. This network of blood vessels supplies the heart muscle with oxygen and nutrients. When the heart is at rest, even an artery that is almost completely blocked may have enough blood flow to meet the needs of the section of heart muscle it supplies. But make the heart work harder, and the clogged vessel may not be able to handle the extra rush of blood needed by the hard-working muscle. This mismatch in demand and supply can cause angina pressure or pain in the chest, jaw, left arm, or elsewhere that comes on with exercise or other stress and disappears with rest.
An exercise stress test can document low blood flow in the coronary arteries. It should be part of the work-up for anyone having angina or who might be a candidate for artery-opening angioplasty. Stress tests are also used to reveal hidden rhythm problems, assess some valves, gauge the safety of an exercise program, and monitor the effectiveness of treatment.
When To Get A Stress Test
The U.S. Preventive Services Task Force, an independent panel that makes recommendations to doctors, urges physicians not to routinely offer exercise stress testing to people without symptoms or strong risk factors for CAD. Physician groups like the American College of Cardiology support this recommendation.
The final decision, though, falls on you and a doctor who knows your health profile. “The guidelines leave a lot to physician judgment, because we’re sometimes in a gray zone where we don’t really know what’s the ‘right’ thing to do for everyone,” Dr. Bhatt says.
Although the tide has turned against exercise stress testing of otherwise healthy men concerned about their heart risk, guidelines say that a stress test could be “considered” in a man who is older and relatively inactive but embarking on a vigorous new exercise program. “In that case I would recommend a stress test,” Dr. Bhatt says.
Stress test results
An exercise stress test is designed to find out if one or more of the coronary arteries feeding the heart contain fatty deposits that block a blood vessel 70% or more. Additional testing is often required to confirm the test result.

Before You Perform A Maximum Heart Rate Stress Test
Before you do a max heart rate test running, you should stop and think about your health and safety. You need to be in good shape and have been running for a while. Beginner runners, especially older ones, should just guess their maximum heart rate.
Hitting the upper limit of what your heart is capable of is called a stress test for a reason. If you have been ill recently or are tired from general lack of sleep or recovery from racing or a tough training block, now is the not the time to do a stress test. It wont give you the right information and risks your health. Save it for when you are prepared. Plan it for when you have an easy week of running leading up to it. Agreed?
St Segment Depressions During Exercise Stress Test
The myocardial ischemia that can be provoked by exercise is located to the subendocardium of the left ventricle. As discussed previously , subendocardial ischemia redirects the ST vector such that it becomes directed from the epicardium to the endocardium, which means that the ST vector will be directed towards the back . Hence, the ST vector is directed away from all chest leads . Chest leads that detect this ST vector will display ST segment depressions . However, leads with ST segment depressions do not necessarily reflect the ischemic area e.g ST segment depressions in leads V3 and V4 do not necessarily imply that the ischemia is located anteriorly.
The T-wave vector may similarly be directed towards the back which yields a negative T-wave . However, the primary ECG manifestation of myocardial ischemia is the ST segment depression and not the T-wave inversion. Myocardial ischemia does not manifest only with T-wave inversions during exercise if there are T-wave inversions during ischemia, there will always be ST segment depressions as well. The ST segment, on the other hand, may be depressed without simultaneous T-wave inversion. In summary:
- ST segment depression is the hallmark of myocardial ischemia on the ECG.
- ST segment depression may be isolated or accompanied by T-wave inversions .
- T-wave inversion never appear without simultaneous ST depression in patients with myocardial ischemia.

What Are The Other Types Of Stress Tests
Dobutamine or adenosine stress test: This is for people unable to exercise. Youâll take a drug to make the heart respond as if you were exercising. This way, the doctor can still determine if there are blockages in the arteries.
Stress echocardiogram: An echocardiogram is a graphic outline of the heart’s movement. A stress echo can accurately visualize the motion of the heart’s walls and pumping action when the heart is stressed it may reveal a lack of blood flow that isn’t always apparent on other heart tests.
Nuclear stress test: This helps figure out which parts of the heart are not working well. A small amount of radioactive substance will be injected into you. Your doctor will use a special camera to see rays emitted from the substance in your body. This will give them clear pictures of the heart tissue on a monitor. These pictures are done at rest and after exercise. Your doctor will be able to spot areas of your heart that arenât getting enough blood. The test could last up to 4 hours to allow enough time for the radioactive substance to flow through your body.
How youâll prepare for these stress tests will vary. Ask your doctor about any specific instructions.
How Do I Prepare For An Exercise Stress Test
To prepare, you should:
- Not eat anything in the hours leading up to the test. If youre having a nuclear stress test, you might not be able to eat until after your test.
- Avoid caffeine for 24 hours before testing. This includes coffee, tea, energy drinks and certain over-the-counter medications.
- Not smoke or use tobacco products.
- Stop taking certain prescription medications the day of your test. These include beta-blockers and asthma inhalers. Talk to your healthcare provider before stopping any medications.
- Try to relax. Its natural to be nervous about heart testing, but feeling anxious can affect your results.
- Wear lightweight, comfortable clothes and sturdy walking shoes.
Are there special preparations people with diabetes need to be aware of?
Its important not to eat before your test. However, you shouldnt skip meals, especially if youre taking diabetes medications. Talk to your diabetes care provider if you need assistance coordinating your meals and medications for test day.
If you own a glucose monitor, bring it with you so you can check your blood sugar levels before and after the test.

Preparing For The Test
Getting ready for an exercise stress test is much like getting ready for a brisk walk or jog around the neighborhood. Wear loose, comfortable clothing and shoes suitable for walking or running. Don’t eat, smoke, or drink beverages containing caffeine or alcohol for three hours before the test.
Your doctor may ask you to stop certain medications that can interfere with the heart’s response to exercise, like a beta blocker or digoxin, a day or more before the test.
If you have diabetes, ask your doctor when and what you should eat before the test, to make sure your blood sugar stays in the right zone. You may be asked to check your blood sugar before the test, and then again soon afterward and once or twice when you get home.
Arrhythmias Occurring During Exercise Stress Testing
Supraventricular and ventricular arrhythmias may occur during exercise. This is more common in persons taking digoxin and those with coffee or alcohol in their blood. The subendocardial ischemia induced by exercise rarely induces any serious arrhythmias. In fact, exercise may actually suppress arrhythmias that are present at rest. For example, ectopic atrial arrhythmias may be suppressed when the sinoatrial node accelerates its discharge frequency ventricular extrasystoles may also be suppressed during exercise. This has no prognostic implication.
The only exercise-induced arrhythmia that is related to coronary artery disease is ventricular tachycardia . Ventricular extrasystoles are common during exercise and they have no prognostic implication .

Why Do You Need To Do A Maximum Heart Rate Stress Test
An essential part of every runners plan is knowing how fast or slow to run for any particular exercise session. This is learned from experience what does this level of effort feel like? and guided by heart rate training zones. One of the most common ways to determine heart rate training zones if a runner doesnt have access to a lab , is via a Heart Rate Zone Calculator. This requires you to know both your Maximum Heart Rate, from a maximum heart rate stress test running, and your Minimum Heart Rate.
If you have access to a reliable heart rate monitor, its really easy to measure it properly with this Maximum Heart Rate Stress Test. Although perhaps straightforward would be a better word than easy, because as you can imagine, getting your heart rate to top out in a max heart rate stress test running requires a fierce effort. If you dont have a chest strap HRM, its worth having one for this test, or ask around someone you know may let you borrow theirs. Wrist based HRMs often have trouble locking on to pulse at the highest effort levels.
If you would like to home in on your Zone2/Z2 heart rate for optimal fat burning adaptations and are comfortable with running for 75+ minutes, then also do the Heart Rate Drift Test soon.
How Long Does The Whole Procedure Take
The stress test itself is a short procedure. But there can be a lot of waiting time before and after. For example, if you get a treadmill stress test with perfusion, you will check in at the front desk at the hospital, wait for the staff to usher you into the stress lab area, and then have the rest imaging part done, then go on the treadmill for the stress component, and then have another series of stress images done. The whole procedure can therefore take in the order of 4-6 hours. We recommend that you take a half day off, at the very least.

Heart Rate Tips To Keep In Mind
- Start at your beginning. Before getting overly concerned about your heart rate, Martin says, its best to simply get moving. If you havent exercised much before, start where youre comfortable and gradually exert yourself more over time.
- Listen to your body. Your body provides other indicators of how hard its working that you need to consider along with heart rate. Pay attention to how hard youre breathing or sweating, and stop if you feel very uncomfortable, Martin says. Devices recording your heart rate have been known to malfunction, for exampleanother reason listening to your body is important.
- Remember that target heart rate is just a guide. Dont get overly fixated on numbers, Martin says. Ideally, they just push you to work a little harder.
