Heart failure (HF) is a major public health problem. In the United States, 5 million<unk> s have heart failure and annually more than one million are hospitalized with heart failure. In addition 50,000<unk> s die of heart failure in the United States. Coronary artery disease (CAD) is the most common cause of heart failure as a result of left ventricular systolic dysfunction (60-68%). There are no randomized studies to evaluate the best strategy to manage coronary artery disease in this<unk>  population. However, there are a number of registry studies that evaluated percutaneous coronary intervention (PCI) and coronary artery bypass surgery (CABG) in<unk> s with coronary artery disease and heart failure.
PCI in the patient with severely depressed ventricular function
PCI in the patient with refractory ventricular arrhythmia
PCI in the patient at risk of bleeding
PCI in the angulated or tortuous lesion
PCI in the patient with in stent restenosis
Antiplatelet therapy to support PCI
Intervention in left main coronary artery disease
Chronic stable angina risk stratification based upon rest left ventricular function
