What is a Stress Myocardial Perfusion Scan (Stress MPI)?
Myocardial perfusion scan is an imaging test to show how well the blood is flowing through the warmheartedness muscle . It also helps find out , how well the muscles are pumping stock . After aheart onslaught , it finds out the expanse of the damaged pump during remainder and while exert .
The stress myocardial perfusion scan utilize a small amount of radioactive fabric known as a radioactive tracer . The tracer bullet journey through the bloodstream where it ’s absorbed by the muscular tissue . The damaged field are not able to steep the tracer bullet .
The stress myocardial perfusion scan looks unlike in the region where tracer has been absorbed and where it is not absorbed .
A stress myocardial perfusion scan assesses the blood period to the heart muscle when it is accent . If the patient is not capable to work out , a sealed medication is give to increase the centre pace or expand the rake vessels as it would pass off during drill .
Who Might Need A Stress Myocardial Perfusion Scan (Stress MPI)?
A strain myocardial perfusion test tells a doc whether the center is getting enough blood . It is also known as a nuclear stress psychometric test .
A someone might need the tension myocardial perfusion trial if :
Pre-Procedure Guidelines
A somebody may be asked to follow a few thing before the strain myocardial perfusion test procedure :
How is a Stress Myocardial Perfusion Scan (Stress MPI) Performed?
Small patches are put on the chest , subdivision , and stage which have wires hook up to a car . This machine tracks the heart rate . A handcuff is put on the arm to memorialise theblood atmospheric pressure .
The patient is asked to exercise either on a treadmill or a wheel . Near the ending of the exercise , a small amount of radioactive material known as the tracer bullet is inserted into the blood stream . This unify with the blood as it is pump through the physical structure .
The patient role is made to lie down on a table and with the help of a gamma camera pic of the nub are direct . The camera will clean the images and show where the rip is get to the marrow and where it is n’t .
If the patient can not practise , a drug that dilates or widen the arteries is given after which tracer is given . After this , the patient rests for some sentence and again the effigy are taken to compare with the late distressed state of matter .
The full stress myocardial perfusion scan process fill up to 4 hours .
Post-procedure
After the emphasis myocardial perfusion scan process , an appointment with the doctor is remove to discuss the result .
The body gets rid of radioactive tracer through weewee or stool in a day . The patient is advised to drink in extra fluid to flush it out well .
The Risk Associated With Stress Myocardial Perfusion Scan (Stress MPI)?
There are a wad of risks associated with myocardial perfusion exam such as :
