Outcome Measures

Primary Outcomes (1)

  • Fractional change in coronary artery diameter and surface area within treated segment

    Will be expressed as a percentage. I.e. we will measure the diameter in mm and area in mm2 before and after.

    3-6 months

Secondary Outcomes (1)

  • Fractional change in coronary artery diameter and surface area with increments from area of treatment

    3-6 months

Study Arms (2)

Receiving drug coated balloon (DCB)

Receiving drug eluting stent (DES)

Eligibility Criteria

Age18 Years+
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients will be included who have received percutaneous coronary intervention with either a drug coated balloon or drug eluting stent and stable symptoms. Patients who have a clinically indicated procedure will be eligible to be recruited as participants. They must also fulfil the inclusion criteria and not be affected by any of the exclusion criteria

You may qualify if:

  • Participant is willing and able to give informed consent for participation in the study.
  • Male or Female, aged 18 years or above.
  • Been treated with percutaneous coronary intervention of either drug coated balloon or drug eluting stent

You may not qualify if:

  • Any contraindications to administration of acetylcholine or GTN
  • History of coronary vasospasm or spontaneous coronary artery dissection
  • Significant medical, surgical or psychiatric disease that would affect subject safety or influence the study outcome according to physician's opinion
  • Patients who received a combination of drug eluting stents and drug coated balloon to the same vessel
  • Significant renal impairment (estimated glomerular filtration rate \<30mL/min/ 1.73m2
  • Body mass index \>35 (may affect coronary artery diameter qualitative assessment)
  • Symptomatic congestive cardiac failure
  • Severe asthma
  • Significant autoimmune inflammatory conditions (for example rheumatoid arthritis)
  • Patients taking immunomodulating drugs (including Methotrexate, Ciclosporin, steroids)
  • Previous heart transplant
  • Relative Anaemia - Haemoglobin \<12g/dL in men and \<10g/dL in women
  • Women of child bearing age with a positive pregnancy test
