<prompt> Answer this question truthfullyWhat is the risk classification for chronic cases of stable angina?  <response>: <reason> Noninvasive Risk Stratification High risk 3 annual death or MI 1. Severe resting LV dysfunction LVEF 35 not readily explained by noncoronary causes 2. Resting perfusion abnormalities 10 of the myocardium in patients without prior history or evidence of MI 3. Stress ECG findings including 2 mm of ST-segment depression at low workload or persisting into recovery, exercise-induced ST-segment elevation, or exercise-induced VTVF 4. Severe stress-induced LV dysfunction peak exercise LVEF 45 or drop in LVEF with stress 10 5. Stress-induced perfusion abnormalities encumbering 10 myocardium or stress segmental scores indicating multiple vascular territories with abnormalities 6. Stress-induced LV dilation 7. Inducible wall motion abnormality involving 2 segments or 2 coronary beds 8. Wall motion abnormality developing at low dose of dobutamine 10 mgkgmin or at a low heart rate 120 beatsmin 9. CAC score 400 Agatston units 10. Multivessel obstructive CAD 70 stenosis or left main stenosis 50 stenosis on CCTA Intermediate risk 1 to 3 annual death or MI 1. Mildmoderate resting LV dysfunction LVEF 35 to 49 not readily explained by noncoronary causes 2. Resting perfusion abnormalities in 5 to 9.9 of the myocardium in patients without a history or prior evidence of MI 3. 1 mm of ST-segment depression occurring with exertional symptoms 4. Stress-induced perfusion abnormalities encumbering 5 to 9.9 of the myocardium or stress segmental scores in multiple segments indicating 1 vascular territory with abnormalities but without LV dilation 5. Small wall motion abnormality involving 1 to 2 segments and only 1 coronary bed 6. CAC score 100 to 399 Agatston units 7. One vessel CAD with 70 stenosis or moderate CAD stenosis 50 to 69 stenosis in 2 arteries on CCTA Low risk 1 annual death or MI 1. Low-risk treadmill score score 5 or no new ST segment changes or exercise-induced chest pain symptoms; when achieving maximal levels of exercise 2. Normal or small myocardial perfusion defect at rest or with stress encumbering 5 of the myocardium 3. Normal stress or no change of limited resting wall motion abnormalities during stress 4. CAC score 100 Agaston units 5. No coronary stenosis 50 on CCTA CAC indicates coronary artery calcium; CAD, coronary artery disease; CCTA, coronary computed tomography angiography; LV, left ventricular; LVEF, left ventricular ejection fraction; and MI, myocardial infarction.Visit the microchapters below:Risk Stratification by Noninvasive Testing Risk Stratification by Coronary Angiography
