Brief Summary

The use of coronary angiography to investigate patients at risk of coronary artery narrowings has become universal. In most cases, this investigation leads to a successful treatment plan with revascularisation recommended where appropriate. However in a substantial number of patients, the images taken of the coronary arteries can lead to diagnostic uncertainty. Increasingly, doctors are using devices called pressure wires to clarify the significance of coronary artery narrowings in order to tailor patient treatment on an individual basis. The Radi pressure wire is well recognised as a reliable tool in assessing whether a narrowing is significant in functional terms, that is, does it significantly restrict blood flow to the heart muscle.It consists of a fine wire that is fed into individual major coronary arteries to measure pressure within the vessel itself. In conjunction with the images taken of the arteries, it is very useful in deciding how best to treat patients. This study enrolls volunteers who are being investigated for stable cardiac-sounding chest pain and are undergoing a coronary angiogram. It will investigate whether the extra information gained from pressure wire assessment will change patients' treatment plan.

Outcome Measures

Primary Outcomes (1)

  • Estimation of Number of Cases Where FFR Data Results in a Change in the Management Strategy (Number of Vessel Requiring Treatment and/or PCI vs Medical vs CABG)

    This outcome measure was assessing agreement in the management plan (MP) derived from angiographic assessment alone compared to a MP derived from angiographic assessment plus the use of FFR data acquired at the time of angiography. The study assessed the proportion of cases in which the angiogram directed MP changed after FFR data were disclosed.

    Up until hospital discharge. Most cases were day cases but no specific data relating to length of stay collected.

Secondary Outcomes (1)

  • To Determine the Level of Agreement in Management Plans Regarding the Significance of Coronary Artery Narrowings When Comparing the MP Acquired by Standard Angiographic Assessment Alone and a MP Acquired Using Angiographic Assessment Plus FFR Data.

    Up to hospital discharge. Most were day case procedures but no specific data relating to discharge was collected.

Interventions

Intracoronary insertion of pressure wire at the time of diagnostic angiography.

Also known as: Radi pressure wire.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients referred for elective coronary angiography under a non-interventional cardiologist for the investigation of chest pain thought to be of cardiac origin.
  • There is no requirement for a test demonstrating objective evidence of myocardial ischaemia because this study aims to recruit consecutive patients in real world current practice
  • Written informed consent
  • No participation in other studies

You may not qualify if:

  • Previous coronary artery bypass graft surgery
  • Acute coronary syndrome at presentation
  • Diagnostic angiography or percutaneous coronary intervention within the previous 12 months
  • Contraindication to adenosine
  • Severe valve disease
  • Creatinine \>180
  • Life threatening comorbidity
  • Diagnostic angiogram showing "normal" coronary arteries defined as no coronary stenosis of \>30% by visual estimate in any epicardial vessel of \>2.25mm diameter
