An Study Looking at Percutaneous Coronary Intervention Outcomes for Octogenarians

3. juni 2026 opdateret af: Fiona Macrae, Gloucestershire Hospitals NHS Foundation Trust

An Observational Study Looking at the Demographics and Outcomes of Octogenarians Undergoing Percutaneous Coronary Intervention (PCI) Over a Seven-year Period at a Primary Percutaneous Coronary Intervention (PPCI) Centre With Off-site Cardiothoracic Support

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.

Detaljeret beskrivelse

The project is a retrospective observational study designed to look at the demographics, clinical presentation, comorbidities, angiographic findings, procedural factors and outcomes of participants aged 80 years and over (octogenarians) who had percutaneous coronary intervention (PCI) at our hospital trust between 1st January 2017 and 31st December 2023. The data will be reviewed to form a detailed description of the characteristics of the cohort. It will then be analysed to determine if there are associations between certain participant variables and outcomes, including inpatient complication rates and the rate of Major Adverse Cardiovascular Events (MACE) at one-year post procedure. The initial data will be identified from the local database which is required to be maintained and submitted to the UK's National Institute for Cardiovascular Outcomes Research (NICOR) database. Missing data or additional data not captured on this database, such as participant frailty and the coronary artery disease severity and complexity (measured by the SYNTAX score), will be collected from a combination of patient letters and Electronic Patient Records (EPR), including blood test results and imaging. Experienced interventional cardiologists will analyse the angiograms to collect the pre and post intervention SYNTAX score in addition to the angiography-derived calcification severity of the culprit artery. The data will be analysed to describe the cohort in detail. Univariate and multivariate cox regression analysis will be used to establish any associations between variables such as participant frailty, angiography-derived calcification severity and residual SYNTAX score with participant outcomes.
