1. 缺血性心力衰竭介入治疗策略 PCI strategies for patients with ischemic heart failure 哈尔滨医科大学附属第一医院 李为民 The First Affiliated Hospital Of Harbin Medical University

2.  Ischemic heart disease is a major health problem worldwide and will eventually progress to heart failure, which is termed as ischemic heart failure (IHF)  Patients with IHF suffer from high rates of ischemic events, arrhythmic events, and mortality

3. Sardi GL. Am J Cardiol 2012;109:344–351

4.  Despite advances in medical treatment, current therapeutic approaches to IHF remain very limited  Revascularization in IHF patients has been proven to recruit hibernating or stunned myocardium in an effort to improve overall myocardial contractility

5. 缺血性心脏病患者如出现心衰症状及体征， 建议评估患者是否需行冠脉造影以明确病 变程度！

6. European Heart Journal (2012) 33, 1787–1847 心衰患者如伴心绞痛症状且适合行血运重建治 疗，建议先行冠脉造影以明确病变程度 !

8. PCI versus CABG  The choice of PCI or CABG in IHF patients is uncertain due to the fact that most studies comparing PCI and CABG in patients with CAD have excluded patients who have significant ventricular dysfunction

9. 对不适合行 CABG 的伴左主干或多支病变的 IHF 患者， PCI 可成为替代的血运重建方式！

10.  A meta-analysis of studies utilizing PCI among patients with IHF was performed to determine in-hospital and long-term mortality  In total, 4766 patients from 19 studies were included in this meta-analysis. The in-hospital mortality was 1.8% and the long-term mortality (24 months) was 15.6%. Five studies compared PCI versus CABG and resulted in similar long- term mortality with relative risk of 0.98 PCI versus CABG Coronary Artery Disease 2012, 23:469–479

11. In-hospital mortality Long-term mortality

12. PCI versus CABG Meta-analysis in IHF patients Total patients: 957 Coronary Artery Disease 2012, 23:469–479

13. The present meta-analysis demonstrates that on the basis of available clinical studies, PCI among patients with left ventricular systolic dysfunction is feasible with acceptable in- hospital and long-term mortality and yields similar outcomes to CABG. Coronary Artery Disease 2012, 23:469–479 PCI versus CABG

14. Complete vs. Incomplete Revascularization by PCI  IHF patients often have multi-vessel disease, leading to a controversy of complete versus incomplete revascularization

15. Definition of CR and ICR

18. CR VS IR in patients without STEMI Three-year follow up (n=873) Song YB et al. Heart vessels, 2012

19. CR VS IR in patients with stable MV 10-year follow up （ n=408 ） Vieira RD, et al. Circulation, 2012

20.  There is a clear trend towards the better outcomes with complete revascularization than with incomplete revascularization,  Interventional cardiologists should make the result as ‘‘CABG-like’’ as possible, and this includes attempted revascularization of CTO Edward L. J Am Coll Cardiol Intv, 2009, 2:17

21. Staged PCI is preferred in the following situations:  STEMI with multivessel disease  Unsatisfying results or acute occlusion ；  Complex lesions, e.g. CTO lesions ；  Longer procedure time or patient intolerance ；

22.  Over-use of contrast agent ；  Elderly patients ；  Severe cardiac or kidney dysfunction ；  Two or more lesions supplying large areas ； Staged PCI

23. Pros and Cons of staged PCI  Complete revascularization  Reduced single procedure time and contrast agent  Lower incidence of heart failure and CIN  Correction of in-stent restenosis from initial PCI Increased medical costs Treatment of asymptomatic lesions Uncertain timing of staged PCI

24. Use of percutaneous circulatory support devices ECMO IABPTandemHeart Impella

25. Percutaneous circulatory support devices are beneficial for short-term use to stabilize IHF patients undergoing PCI or as “bridges” to cardiac transplantation

26. PCI Combination of PCI and CRT in IHF patients CRT Acute ischemic heart disease × × Ventricular remodeling Ventricular dyssynchronization Coronary occlusion Chronic ischemic heart disease × Hibernating or stunned myocardium

27. Inclusion criteria Patients with IHF (n=7) NYHA Ⅲ～ Ⅳ级 QRS  130 ms LVEF  0.4 LVEDD  55 mm Optimal medication Yaling Han. Chinese Journal of Cardiology, 2005, 33:17 Right Atrial Lead Right Ventricular Lead Left Ventricular Lead

28.  For IHF patients with indication for both PCI and CRT, the combination of PCI and CRT could improve their cardiac function, quality of life, and prognosis  The underlying mechanism and long-term efficacy of the combined therapy needs to be further exploited Yaling Han. Chinese Journal of Cardiology, 2005, 33:17

29. Stem-cell therapy for IHF Limitations of current therapies have led to research aimed at regenerating and repairing ischemically damaged myocardium through stem-cell therapy

30. Still Controversial

31. Stem-cell therapy for IHF is very promising. However, major issues still need to be resolved.  To test and confirm the most beneficial subpopulations of autologous stem cells  To identify the optimal dosage and timing of cell therapeutics  To produce optimum cell delivery and homing capacity  To explain and explore the mechanisms of cell therapy in humans (paracrine or myocardial regeneration or both)
