Overview

Prospective cohort study evaluates CI-AKI's impact on short- to medium-term survival in ACS patients, indicating high mortality risk.

Key Points

  • To assess the incidence of contrast-induced acute kidney injury (CI-AKI) and its influence on survival in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).
  • Conducted a prospective cohort study with 192 ACS patients undergoing PCI.
  • Collected sociodemographic, clinical, laboratory, and procedural data.
  • Analyzed CI-AKI incidence using Poisson regression to estimate relative risks.
  • Assessed survival using a multivariable Cox proportional hazards model.
  • CI-AKI occurred in 33% of the patients analyzed.
  • Patients with CI-AKI had a 15% higher mortality rate.
  • CI-AKI was associated with a 4.7-fold increased hazard of death within 90 days.
  • Advanced age, hypertension, chronic kidney disease, vasoactive drug use, and cardiorespiratory arrest were identified as risk factors.
