Right ventricular branch compromise after percutaneous coronary intervention and baseline chronic kidney disease: A high-risk combination associated with long-term prognoses in acute inferior myocardial infarction

•Right ventricular branch compromise (RVBC) after percutaneous coronary intervention (PCI) is associated with poor short-term prognosis.•We investigated long-term prognosis after RVBC in patients with acute inferior myocardial infarction.•Baseline chronic kidney disease (CKD) and RVBC are risk factors for poor long-term prognosis.•RVBC after primary PCI causes persistent cardiogenic shock and cardiorenal syndrome.•RV perfusion after primary PCI in patients with baseline CKD is critical.
