Contemporary Management of Myocardial Ischemia Epidemiology of chronic ischemia (angina) Persistent ischemia (angina) despitecurrent drug therapy Persistent ischemia (angina) despite PCI Persistent ischemia (angina) despite optimal revascularization Myocardial ischemia: Significant clinical burden Myocardial ischemia diminishes quality of life Coexistence of myocardial ischemia and depression

Myocardial Ischemia:View from the Vessel Wall Causes of inadequate myocardial O2 supply Ischemia is related to myocardial O2 supply and demand Symptoms occur at end of ischemic cascade Obstructive plaque and ischemia Impaired microvascular perfusion in the anginal syndrome Subendocardial hypoperfusion: Association with anginal syndrome Accumulating evidence implicates coronary microcirculation dysfunction in IHD

Practical Considerations in Chronic Ischemic Heart Disease Management Angina treatment: Objectives Comprehensive management of myocardial ischemia CAD: Treatment challenges ACC/AHA guidelines: Chest pain evaluation ACC/AHA guidelines: Chronic stable angina treatment Substantial growth in PCI Stable CAD: PCI vs conservative medical management Major benefit of PCI: Angina symptom relief CAD progression: Major cause of post-revascularization angina Conditions limiting repeat revascularization Diabetes and PCI: Factors influencing outcome CARISA: Ranolazine benefits patients with and without diabetes CARISA: Ranolazine reduces A1C Selective vs routine catheterization: Cost reduction Chronic stable angina: Pharmacotherapy CRUSADE: Nonpharmacologic interventions at discharge CRUSADE: Discharge medications following UA/NSTEMI How important is IHD in women? AHA guidelines: Chest pain evaluation in women IHD vasculopathy: Gender differences Ischemia in women: Microvascular dysfunction Less obstructive CAD: Women vs men Women have more adverse outcomes vs men Higher incidence of major CV events in women Increased risk of death/MI in women with CAD CRUSADE: Gender and discharge medications Euro Heart Survey: Undertreatment of women
