Study Notes
Non-Invasive Cardiac Testing Overview
- Stress testing modalities include exercise (treadmill), vasodilator (adenosine, regadenoson), and inotropy (dobutamine).
- Imaging modalities for stress testing include ECG, TTE, SPECT, PET, and MRI.
- Exercise Tolerance Test (ETT) is preferred over pharmacologic testing if the patient can reach goal exertion.
- Diagnostic criteria for exercise stress testing include reaching >85% max-predict HR, peak double product >20k, and HR recovery >12.
- Pharmacologic stress tests are used for imaging only and involve choosing agents like adenosine/regadenoson or dobutamine.
- Viability testing is used to determine the viability of ischemic myocardial tissue and involves SPECT, PET, TTE, or MRI.
- Rest imaging includes the use of coronary CTA to evaluate the presence and extent of CAD.
- Coronary CTA should not be used to screen asymptomatic patients and is indicated for low to moderate risk patients.
- Coronary Artery Calcium (CAC) scans provide risk assessment scores for CAD and ASCVD risk stratification.
- Cardiac MRI is the modality of choice for assessing the functional and tissue properties of the heart.
- Different echocardiography views, such as parasternal long axis, apical 4 chamber, and parasternal short axis, are used to assess various aspects of cardiac function and anatomy.
- Echocardiography helps in assessing LV size, function, wall thickness, MV/AoV function/flow, RV/LV size, function, thrombus, septal size/motion, and pericardial effusion.
