1 Arthur Stillman, M.D., Ph.D., PI Pamela Woodard, M.D., Study Co-chair Randomized Evaluation of Patients with Stable Angina Comparing Utilization of Diagnostic Examinations

2 COURAGE Trial 2287 patients with stable angina (CCS I-III) At least one vessel with ≥ 70% stenosis Objective evidence of ischemia Randomized to OMT vs. OMT + PCI Mean f/u 4.6 years No difference in death or MI or anginal symptoms Boden WE, et al. N Engl J Med. 2007 Apr. 12;356(15):1503–1516.

3 Primary Aim To compare outcomes of participants with symptoms of stable angina or angina equivalent evaluated with an anatomic imaging strategy using CCTA as initial method of CAD diagnosis (Group A) to a combined functional and anatomic imaging strategy of SPECT MPI/ICA (Group B) as a guide to OMT.

4

5 Secondary Aims To evaluate the ability of available prognostic indices to predict revascularization or MACE using CCTA information and to develop new indices using the RESCUE trial data. To determine the cost, effectiveness, and incremental cost- effectiveness of CCTA versus SPECT MPI/ICA in the evaluation of participants with symptoms of stable angina. To compare angina symptoms and self-reported health status of participants with symptoms of stable angina undergoing CCTA as initial method of CAD diagnosis to SPECT MPI/ICA as a guide to OMT.

6 Eligibility Patients ages 40 or older presenting with symptoms of stable angina CCS Class I to III or angina equivalent, with or without known CAD, with planned non-invasive imaging for diagnosis may enroll in the study

7 Inclusion Criteria Willing and able to provide a written informed consent; 40 years or older; Presentation with symptoms of stable angina (CCS Class I to III) or angina equivalent with or without known CAD; Planned non-invasive imaging for CAD diagnosis; Able to tolerate CCTA or SPECT MPI per randomization as required by protocol, to be performed at an ACRIN- qualified facility with a RESCUE-qualified scanner.

8 Exclusion Criteria Prior revascularization; NOT SUITABLE TO UNDERGO CT WITH AN IODINATED CONTRAST AGENT: Known allergy-like reaction to contrast media Renal insufficiency or failure (GFR) < 30 mL/min/1.73 m 2 Atrial fibrillation or significant arrhythmia AMI Unstable angina and symptoms refractory to maximal oral and intravenous medical therapy (persistent CCS Class IV); History of known left ventricular ejection fraction < 45%; Acute ischemia Pregnant Pacemaker

9 Exclusion Criteria cont. Pulmonary edema or heart failure unresponsive to std medical therapy; Valvular heart disease likely to require surgery in 18 months; Congenital heart disease or cardiomyopathy likely to affect prognosis during follow up; Significant hypertension unresponsive to medical therapy; Severe non-cardiovascular comorbidity - survival < 12 months); Prior imaging evaluation for this episode of symptoms within 72 hours BMI >40kg/m 2

10 What is OMT? Antiplatelet such as aspirin or clopidogrel, if participant is aspirin intolerant Statin with target LDL cholesterol of 70 mg/dL Anti-hypertensive/anti-anginal beta blocker with BP goal of 130/80 Hg/mm and reduced CCS angina class Additional anti-hypertensive (amlodipine or ACE-inhibitor) as needed Additional anti-anginal, as needed

11 What is OMT? ACE-inhibitor (lisinopril) or angiotensin II receptor antagonist (Losartan) if ACE-inhibitor not tolerated, for all participants with LV EF <=40% Attempt to raise HDL cholesterol, > 40 mg/dL in men and > 50 mg/dL in women, with exercise, extended release niacin or fibrates alone or in combination once LDL is at goal Medications for diabetes control, with target HbA1c< 7% Smoking cessation Exercise regimen appropriate to diagnosis Nutritional/dietary modification
