This document provides information about stress tests, including:
- Stress tests evaluate how the heart functions under physical stress by monitoring heart rate, blood pressure, and other vital signs during exercise or pharmaceutical stress.
- There are three main types of stress tests: exercise stress tests, adenosine stress tests which use drugs, and nuclear stress tests which use radioactive tracers.
- Stress tests can indicate problems with blood flow, identify areas of reduced flow, and evaluate the effectiveness of heart treatments. They are used to investigate symptoms, assess cardiac function, and follow up on conditions like heart disease.

Chest X-ray:
The chest X-ray is a noninvasive tool used to visualize internal structures, such as the heart, lungs, soft tissues, and bones.
Most chest X-rays are taken while the patient is inhaling so that the lungs are fully expanded.
Several types of chest X-rays can be used to assess heart size, contour, and position; other types reveal cardiac and pericardial calcification as well as physiologic alterations in pulmonary circulation.
Cardiac catheterization (kath-uh-tur-ih-ZAY-shun) is a procedure used to diagnose and treat cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in your groin, neck or arm and threaded through your blood vessels to your heart.
Using this catheter, doctors can then do diagnostic tests as part of a cardiac catheterization. Some heart disease treatments, such as coronary angioplasty, also are done using cardiac catheterization.
Usually, you'll be awake during cardiac catheterization, but given medications to help you relax. Recovery time for a cardiac catheterization is quick, and there's a low risk of complications.

Exercise Stress Test Tredmill test by mohsin.pptxMohsinAli322520
1)An Exercise stress test helps determine how well your heart responds during times when it's working its hardest. It typically involves walking on a treadmill or pedaling on a stationary bike while hooked up to an EKG to monitor your heart’s activity.
2 )what is stress test ?
A stress test is a very commonly performed test to learn:
How well your heart pumps blood.
Whether your heart is receiving an adequate blood supply.
How you perform on physical activity (riding a treadmill or stationary bike) compared with other people your age and sex.
If your symptoms (chest discomfort, shortness of breath, feeling like your heart is racing or even dizziness) can be reproduced while performing physical activity.
3) how does Exercise stress test work ?
4 )why need of stress test indications ?
You may need this test to detect heart problems like:
Congenital heart disease.
Heart failure.
Coronary artery disease.
Heart valve disease.
Hypertrophic cardiomyopathy.
People with high-risk occupations (like pilots or professional athletes) may also need stress tests.
This test may be right for you if you have symptoms of heart disease, like:
Angina, which is chest pain or discomfort due to poor blood flow to the heart.
Arrhythmia, which is a rapid or irregular heartbeat.
Shortness of breath .
Feeling lightheaded or dizzy.
Stress tests are also for people with a heart disease diagnosis who:
Would like to start exercising.
Are undergoing treatment and healthcare providers need to determine how well it’s working.
Face a higher risk of complications due to a personal or family history of heart disease.
Have diabetes or other underlying conditions that increase your risk of heart disease.
different types of stress test ?
There are many methods for assessing heart function while it’s 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
Exercise stress echocardiogram
Nuclear stress test
Time taken by stress test ?
If you’re undergoing a basic stress test, the exercise portion lasts about 10 to 15 minutes. Additional time is necessary for getting ready to exercise and recovering afterward.
Stress tests that include echocardiography, nuclear imaging or MRI often are longer and may require you to be in the stress lab for several hours.
Preparation for exercise stress test ?
Not eat anything in the hours leading up to the test. If you’re 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.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

• Indications
• Patient preparation
• Technique
• contraindications
CONTENTS
5. Stress test
• also called an exercise stress test, shows how your
heart works during 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 your
heart rhythm, blood pressure and breathing
are monitored. Or you'll receive a drug that
mimics the effects of exercise.
6. Types of stress test:
Generally ,there are three types of stress
test:
• adenosine stress test
• echocardiogram stress test
• nuclear stress test
7. Types of stress test
• Adenosine Stress Test:
This test is used in people who are unable to
exercise. A drug is given to make the heart respond
as if the person were exercising. This way the doctor
can still determine how the heart responds to stress,
but no exercise is required.
• Stress echocardiogram:
An echocardiogram (often called "echo") 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.
8. Nuclear stress test:
• This test helps to determine which parts of the heart
are healthy and function normally and which are not.
• A very small and harmless amount of radioactive
substance is injected into the patient.
• Then the doctor uses a special camera to identify the
rays emitted from the substance within the body; this
produces clear pictures of the heart tissue on a monitor.
• These pictures are done both at rest and after exercise.
• Using this technique, a less than normal amount of
thallium will be seen in those areas of the heart that
have a decreased blood supply
9.
10. Indications:
• Symptoms suggesting myocardial ischemia
• Acute chest pain in patients excluded for acute
coronary syndrome (ACS)
• Recent ACS treated without coronary angiography
• Known CAD with worsening symptoms
• Prior coronary revascularization (patients 5 years or
longer after Coronary artery bypass grafting [CABG] or
2 years or less after percutaneous coronary
intervention [PCI])
• Certain cardiac arrhythmias to assess chronotropic
competence
• Newly diagnosed heart failure or cardiomyopathy
Your doctor may recommend a test with imaging, such
as a nuclear stress test or echocardiographic stress test, if
an exercise stress test doesn't pinpoint the cause of your
symptoms.
11. Patient preparations
• not to eat, drink or smoke for a period of
time before a stress test.
• to avoid caffeine the day before and the day
of the test.
• Wear or bring comfortable clothes and
walking shoes.
• If you use an inhaler for your breathing,
please bring it to the test.
• Your stress test will take around an hour,
including both your prep time and the time it
takes to perform the actual test. The actual
test takes only around 15 minutes.
12. Technique
• is performed in a designated lab, supervised by
a trained healthcare personnel.
• Electrodes are placed on the chest, which is
attached to an ECG machine that is recording
the electrical activity of the heart.
• Your resting ECG, heart rate, and blood
pressure are obtained prior to starting the
exercise regimen.
• The baseline ECG should be evaluated closely
prior to starting the exercise portion of the
test.
• If any of ECG abnormalities are noted, the test
should be performed with the addition of
imaging modality.
• The resting ECG is usually obtained both
supine and standing.
13. • Once it is determined, the patient is placed on a
treadmill with a designed protocol that increases in
intervals as you exercise.
• Blood pressure and heart rate are monitored
throughout exercise, and the patient is monitored for
any developing symptoms such as chest pain,
shortness of breath, dizziness or extreme fatigue.
• The most common protocol used during treadmill
exercise stress testing is the Bruce protocol. This
protocol is divided into successive 3-minute stages,
each of which requires the patient to walk faster and
at a steeper grade. The testing protocol could be
adjusted to a patient’s tolerance, aiming for 6 to 12
minutes of exercise duration.
• There are a number of other protocols for patients
who have a limited exercise tolerance; however,
other methods that do not include exercise are also
available for such patients.
15. What you can expect?
Before stress test:
First, your doctor will ask some
questions about medical history
and how often and strenuously
you exercise. This helps
determine the amount of exercise
that's appropriate for you during
the test.
Your doctor will also listen to your
heart beat and lungs for any
abnormalities that might affect
your test results
16. During stress test:
• technician will place (electrodes) on your chest,
legs and arms. The electrodes have wires connected
to an electrocardiogram machine, which records the
electrical signals that trigger your heartbeats.
• A cuff on your arm checks your blood pressure
during the test.
• You may be asked to breathe into a tube during the
test to show how well you're able to breathe during
exercise.
• If you're not exercising, your doctor will inject the
drug into your IV that increases blood flow to your
heart. You might feel flushed or short of breath, just
as you would if you were exercising. You might get a
headache.
• You and your doctor will discuss your safe limits for
exercise. You may stop the test anytime you're too
uncomfortable to continue exercising.
17. After stress test
• After you stop exercising, you may be
asked to stand still for several seconds
and then lie down for a period of time
with the monitors in place.
• Your doctor can watch for any
abnormalities as your heart rate and
breathing return to normal.
• If the information gathered during
your exercise stress test shows your
heart function to be normal, you may
not need any further tests.
18. Stress test
Benefits
• how well the heart is pumping
blood
• whether there is any damage to the
heart
• if there is any blockage or
narrowing of the coronary arteries
that provide blood to the heart
• the effectiveness of any current
treatment.
• A stress test usually involves
walking on a treadmill or riding a
stationary bike your heart rhythm,
blood pressure and breathing are
monitored.
Risk factors
• allergic reaction to the dye
• abnormal heart rhythms, or
arrhythmias
• fall in blood pressure during or
after exercise, possibly leading
to dizziness or faintness
• chest pain
• nausea
• trembling
• headache
• shortness of breath
• anxiety
19. Contraindications
• Acute myocardial infarction within 2 to 3 days
• Unstable angina not previously stabilized by medical therapy
• Uncontrolled cardiac arrhythmias
• Symptomatic severe aortic stenosis
• Uncontrolled symptomatic heart failure
• Acute pulmonary embolus or pulmonary infarction
