The goal of this observational study is to understand the makeup of the participants aged 80 years and older who had stents fitted or balloon expansion of their heart arteries, otherwise known as percutaneous coronary intervention (PCI), at our hospital over a seven year period. The investigators will aim to describe the cohort with respect to their health conditions, age and frailty in addition to whether their procedure was planned or an emergency. The investigators will also look at the outcomes of these participants up to one year post procedure. The secondary aim is to look for associations between participant variables and their outcomes in hospital and at 1 year. The specific outcomes the investigators will look at are: inpatient complications and the incidence of heart attacks, strokes, unplanned PCI, cardiac rehospitalisation or death.
Participants who had PCI at our hospital trust between 1st January 2017 - 31st December 2023.
Participants with negative pressure wire studies (i.e. the lesion identified was not flow restricting).
Participants had "failed PCI".
Participants with significantly incomplete data despite thorough review of the electronic records.
