Introduction
Little observational data exist on the outcome of diagnostic cardiac catheterisation (DCC) in older people. In England and Wales, the population aged over 80 years is growing faster than any other age group.1DCC in these older patients may reveal widespread and complex coronary disease less suitable for percutaneous coronary intervention (PCI), and age-related comorbidity may preclude surgical intervention.
We conducted a retrospective, case-controlled study to examine the outcome, influence on management and complications of DCC in patients aged 80 years and older. The findings were compared with patients aged less than 70 years
