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

Abstract

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.
