An Study Looking at Percutaneous Coronary Intervention Outcomes for Octogenarians

June 3, 2026 updated by: 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.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Participants who had PCI at our hospital trust between 1st January 2017 - 31st December 2023 and were aged 80 years and older.

Description

Inclusion Criteria:

  • Participants who had PCI at our hospital trust between 1st January 2017 - 31st December 2023.

Exclusion Criteria:

  • 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.
