Are there any medical complications from myocardial perfusion scan that would cause coughing?

No. The scan itself should not cause a cough. However, you may experience a cough after performance of a stress treadmill test (due to exercise induced asthma) or performance of pharmacologic stress (due to dilation of pulmonary vessels).

What is the purpose of a myocardial perfusion scan?

Nuclear stress test. This is a specialized form of stress test used to confirm the presence of coronary artery disease in patients suspected of having this problem. It uses a low-level nuclear tracer to assess blood flow to the heart muscle before and after exercise-induced stress. In patients who cannot exercise, other pharmacologic means can be used such as adenosine, lexiscan, persantine, or dobutamine.
Assess risk. 1. Determine blood flow to the heart at rest and at stress. The difference between these two can help determine risk of a major cardiac event such as a heart attack. 2. Determine cardiac size. 3. Determine cardiac function (left ventricular ejection fraction). 4. Determine exercise capacity. 5. Determine electrical (ECG) response to stress. These factors are used to help guide medical therapy.
Cardiac blood supply. A cardiac perfusion scan measures the amount of blood supplied to your heart muscle. Radiotracers such as thallium or technetium sestamibi are injected intravenously and travel through blood to heart muscle. Two sets of images are made during rest and exercise and compared. Indications for this study include chest pain, previous heart attack, heart surgery and coronary artery disease.

What is the function of a myocardial perfusion scan?

Blood flow to heart. It shows blood flow to the heart. It can show old scar of a heart attack or heart muscle that is not getting enough blood, which could mean a future heart attack.

Detection of angina. A myocardial perfusion study is performed in order to detect blockage of the coronary (heart) arteries using intravenous injection of radiotracers which will have a distribution proportional to the blood flow. Studies are performed at rest and after stress or pharmacological stress and then compared to each other. This will help detecting ischemia (angina) or infarction (heart attack).

Can I eat food before having myocardial perfusion scan?

No. No because the blood flow to stomach increased and it makes the image less accurate.
Yes. In general, a light meal is ok but a heavy meal is not recommended. Check with the clinic where you are going to have the test to get their recommendations.

Can someone drive home after a myocardial perfusion scan?

Yes. You can drive home unless you are administered a medication for relaxation during the test as is sometimes necessary for people with severe claustrophobia. However, this is very, very rare because nuclear cameras are so open. Nearly 100% of the people who get a myocardial perfusion scan can drive home safely after the test.
Yes. No sedatives or anesthesia is used for myocardial scans. Isotopes that selectively go to heart muscle are used. These radio pharmaceuticals do not have any effect that would prevent driving home. If test includes physical stress, patient will recover to normal state before leaving department. Cardiologist is continually monitoring heart beat, blood pressure, etc.

What is the definition or description of: myocardial perfusion scan with exercise?

Stress test. This is a type of stress test which uses exercise to increase the heart rate and stress the heart and then a tracer molecule is injected into an IV which shows normal and abnormal blood flow in the heart. This is compared to images at rest to determine whether there has been a heart attack or if there are concerning blockages of the coronary arteries.
Nuclear stress. Its a stress test with a nuclear tracer to see if their is a blockage in your arteries to your heart.
Cardiac blood supply. A cardiac perfusion scan measures the amount of blood supplied to your heart muscle. Radiotracers such as thallium or technetium sestamibi are injected intravenously and travel through blood to heart muscle. Two sets of images are made during rest and exercise are compared.

MIBI, Thallium scan. Myocardial perfusion study refers to the use of radionuclide to evaluate the degree of blood flow (also called perfusion)in the arteries of the heart (coronaries). The injection of the radiotracer (3 different ones : mibi. Myoview, or thallium) is performed at rest, at peak stress (treadmill) or after pharmacological intervention to help detecting coronary artery disease.
Cardiac Exam. Myocardial perfusion imaging looks at blood flow to the left ventricle. This is primarily accomplished using nuclear techniques such as pet or spect using radiotracers such as tl-201, tc-99m, or n-13 ammonia. When it is done with exercise, the myocardial perfusion scan shows blood flow during exercise, and usually compares that to perfusion at rest in order to evaluate for inducible ischemia.
