The nuclear stress test exhibits a sensitivity of 81% and a specificity ranging from 85 to 95%. [22] To arrive at the patient's post test likelihood of disease, the interpretation of the stress test result necessitates the integration of the patient's pretest likelihood with the test's sensitivity and specificity.
A mnemonic can be used for some causes of ST depression, namely DEPRESSED ST: [citation needed]. D - Drooping valve (mitral valve prolapse) E - Enlargement of the left ventricle P - Potassium loss R - Reciprocal ST depression (e.g. inferior wall MI) E - Encephalon hemorrhage S - Subendocardial infarct S - Subendocardial ischemia E - Embolism (pulmonary) D - Dilated cardiomyopathy S - Shock T ...
Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle (). [1]It evaluates many heart conditions, such as coronary artery disease (CAD), [2] hypertrophic cardiomyopathy and heart wall motion abnormalities.
However, if stress imaging is normal, it is unnecessary to perform rest imaging, as it too will be normal – thus stress imaging is normally performed first. MPI has been demonstrated to have an overall accuracy of about 83% ( sensitivity : 85%; specificity : 72%), [ 13 ] and is comparable (or better) than other non-invasive tests for ischemic ...
Diagnose myocardial infarct via physical exam and EKG (plus blood test) A diagnosis of myocardial infarction is created by integrating the history of the presenting illness and physical examination with electrocardiogram findings and cardiac markers ( blood tests for heart muscle cell damage ).
When Chris Kirmsse couldn’t complete a nuclear stress test this fall because her blood pressure was too high, she had to monitor it at home. Her daughter, Christine Kirmsse, a travel nurse ...
The most common tests used are an electrocardiogram, an exercise stress test, and a coronary angiography. [29] A variety of laboratory tests may be ordered. An important laboratory test to determine if myocardial damage has occurred is a cardiac troponin value. [20]
A physician may recommend cardiac imaging to support a diagnosis of a heart condition. Medical specialty professional organizations discourage the use of routine cardiac imaging during pre-operative assessment for patients about to undergo low or mid-risk non-cardiac surgery because the procedure carries risks and is unlikely to result in the change of a patient's management.
