text: 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.
option_0: PCI in the patient with severely depressed ventricular function
option_1: PCI in the patient with refractory ventricular arrhythmia
option_2: PCI in the patient at risk of bleeding
option_3: PCI in the angulated or tortuous lesion
option_4: PCI in the patient with in stent restenosis
option_5: Antiplatelet therapy to support PCI
option_6: Intervention in left main coronary artery disease
option_7: Chronic stable angina risk stratification based upon rest left ventricular function
