Clinical Predictors of Risk for Decreased Cardiac Tissue Perfusion After Percutaneous Coronary Intervention: A Retrospective Cohort Study

OBJECTIVE To establish clinical predictors of risk for decreased cardiac tissue perfusion (DCTP) after percutaneous coronary intervention (PCI). METHODS Data on demographic, anthropometric, clinical, and procedural variables were collected as explanatory from a database of 1,542 adult patients undergoing PCI. A diagnosis of periprocedural myocardial infarction was used to confirm DCTP. A multivariate logistic regression determined the predictors of DCTP. RESULTS The independent predictors of risk for DCTP were age (OR = 1.02, CI 95% = 1.01-1.03, p = .008), multivessel disease (OR = 1.79, CI 95% = 1.30-2.46, p <.001) and intraprocedural lesion complications (OR = 4.56, CI 95% = 3.03-6.87, p <.001). CONCLUSION AND IMPLICATIONS FOR NURSING PRACTICE These results increase the level of evidence of risk for DCTP by refining its risk factors and can support nurses' clinical judgment.
