Diagnosis of SIHD Invasive Testing for diagnosis of Coronary Artery Disease in Patients with Suspected SIHD: Recommendations Class l Coronary angiography is useful in patients with presumed SIHD who have unacceptable ischemic symptoms despite GDMT and who are amendable to, and candidates for, coronary revascularization. (Level of Evidence: C) Class lla Coronary angiography is reasonable to define the extent and severity of coronary artery disease (CAD) in patients with suspected SIHD whose clinical characteristics and results of noninvasive testing (exclusive of stress testing) indicate a high likelihood of severe IHD and who are amendable to, and candidates for, coronary revascularization. (Level of Evidence: C) Coronary angiography is reasonable in patients with suspected symptomatic (SIHD) who cannot undergo diagnostic stress testing, or have indeterminate or non-diagnostic stress tests, where there is a high likelihood that the findings will result in important changes to therapy. (Level of Evidence: C) Class llb Coronary angiography might be considered in patients with stress test results of acceptable quality that do not suggest the presence of CAD when clinical suspicion of CAD remains high and there is a likelihood that the findings will result in important changes to therapy.

Coronary Angiography is Indicated in the Following Subsets for Risk Stratification Patients with heart failure and/or reduced ejection fraction. Patients who have experienced sudden cardiac death or sustained ventricular arrhythmia. Patients undergoing preoperative cardiovascular evaluation for non-cardiac surgery (including solid organ transplantation). Evaluation of cardiac disease among patients who are kidney or liver transplantation candidates. J Am Coll Cardiol 2014 Jul 18 and Circulation 2014 Jul 28 [Epub ahead of print]
Diagnostic Coronary Angiography Without Stress Testing in ISHD May Be Indicated: Long-standing diabetes mellitus and end-organ damage Severe peripheral vascular disease (e.g., abdominal aortic aneurysm) Previous chest (mantle) radiation therapy may have severe CAD – particularly when ischemic symptoms are present Patients with a combination of typical angina, transient heart failure, pulmonary edema, or exertional or unheralded syncope may have severe CAD Non-invasive testing such as rest echocardiography revealing multiple regional wall motion abnormalities or electrocardiography with diffuse ischemic changes in multiple territories Clinicians strongly suspect that s stress test is falsely negative (e.g., a patient with typical angina who also has multiple risk factors for CAD), diagnostic angiography may be warranted When stress testing yields an ambiguous or indeterminate result in a patient with a high likelihood of CAD, coronary angiography may be preferable to another non-invasive test and may be the most effective means to reach a diagnosis.

Recommendation for Chelation Therapy 2012 Recommendations 2014 Focused Updated Recommendation Comment Class lll: No Benefit Class llb From TACT Trial Chelation therapy is not recommended with the intent of improving symptoms or reducing cardiovascular risk in patients with SIHD.

(Level of Evidence: B) Modified recommendation (changed Class of Recommendation from lll: No benefit to llb and Level of Evidence from C to B).

to Improve Survival Recommendation for CAD Revascularization Class l 2012 Recommendations 2014 Focused Updated Recommendation Comment Class lla Class l CABG is probably recommended in preference to PCI to improve survival in patients with multiple CAD and diabetes mellitus, particularly if a LIMA graft can be anastomosed to the LAD artery. (Level of Evidence: B) A Heart Team approach to revascularization is recommended in patients with diabetes mellitus and complex multivessel CAD. (Level of Evidence: C) CABG is generally recommended in preference to PCI to improve survival in patients with DM and multivessel CAD for which revascularization is likely to improve survival (3-vessel CAD or complex 2-vessel CAD involving the proximal LAD). Particularly if a LIMA graft can be anastomosed to the LAD artery, provided that patient is a good candidate for surgery.

CABG vs. PCI for Complex/LM CAD
Summary - To address the important issue of deciding between PCI and CABG in patients with diabetes mellitus and complex multi-vessel CAD, a Heart Team approach would be beneficial. - This was an integral component of the FREEDOM, SYNTAX, and BARI trials and is therefore emphasized in this setting. - The Heart Team is a multidisciplinary team composed of the referring cardiologist, an interventional cardiologist and a cardiac surgeon who jointly: Review the patient’s medical condition and coronary anatomy Determine that PCI and/or CABG are technically feasible and reasonable Discuss revascularization options with the patient before a treatment strategy is selected.

Take Home Message: Updated role of FFR in PCI and SIHD guidelines Randomized trials incorporating FFR guided PCI have shown lower MACE/MI/TVR rates and stent usage but no impact on survival. Recent long-term registry data also could not substantiate reduced mortality in FFR guided PCI. CABG now is the Class I indication for multi-vessel CAD in diabetic pts (3 V or complex 2 V CAD with high Syntax score >22 & suitable for LIMA graft & acceptable surgical risk). Heart Team approach in deciding final revascularization in these complex CAD pts is appropriate. Some of these pts may benefit from PCI.
