An Updated Systematic Review and Meta-analysis of the Short- and Long-term Outcomes of Percutaneous Coronary Intervention for Patients with Severe Left Ventricular Systolic Dysfunction

Background: Coronary artery disease (CAD) is the most common cause of left ventricular dysfunction (LVD). Confl icting evidence exists with regards to available treatments and patient prognosis. Revascularization may improve ventricular function while coronary artery bypass surgery (CABG) has signifi cantly improved survival. The effectiveness of percutaneous coronary intervention (PCI) has also not been thoroughly investigated to date.
