Abstract

  OBJECTIVE: The aim of this study was to revisit findings from previous  studies reporting that pet ownership improves outcome following an  admission for acute coronary syndrome (ACS). METHOD: Four hundred and  twenty-four patients admitted to a cardiac unit with an ACS completed  questions regarding pet ownership in hospital. Rates of cardiac death and  readmission were assessed 1 year following hospitalization. RESULTS: Pet  owners were more likely to experience a death or readmission following  their hospitalization, after controlling for key psychosocial and medical  covariates. When dog and cat owners were considered separately, cat  ownership was significantly associated with increased risk of death or  readmission. CONCLUSION: In this independent study, pet ownership at  baseline, and cat ownership in particular, was associated with increased  cardiac morbidity and mortality in the year following an admission for an  acute coronary syndrome, a finding contrary to previous reports.
