Optimizing Strategy of Coronary Revascularization in Patients With Multivessel Lesions Combined Heart Failure

As the end stage of almost all cardiovascular diseases, heart failure has become an increasingly common cause of cardiovascular morbidity and mortality worldwide. In China, coronary artery disease (CAD) has become the main cause of heart failure in recent years. CAD combining with heart failure usually predicts poor outcome, with coronary revascularization the most universally used therapy. However, the difference of several types of such therapy has less well been compared. Thus, the study mainly aims to compare different types of coronary revascularization therapies such as Percutaneous Coronary Intervention (PCI),Coronary Artery Bypass Grafting (CABG) as well as Hybrid Coronary Revascularization (HCR), and also make the optimization strategy especially in patients with heart failure. The study also aims to investigate whether disease progression in patients with chronic heart failure (CHF) can be assessed by new biomarkers and determine their diagnostic and prognostic value, relating several cardiac functional parameters to clinical outcome.
