NCT03850015

Brief Summary

The study will compare standard ultrasound images to high frame rate ultrasound images in patients with heart disease or with a low risk of heart disease to see if a higher frame rate of ultrasound adds to the information obtained from standard ultrasound.

Outcome Measures

Primary Outcomes (1)

  • Agreement between HFR ultrasound and standard ultrasound.

    Demonstration that there is at least 80% agreement between HFR ultrasound techniques and standard techniques. Expressed as as a percentage of the recorded images.

    At 1 year

Interventions

Patients will undergo standard echocardiography, with and without contrast

Following standard echocardiography, the test is repeated using high frame rate ultrasound

Study Population

25 patients will be recruited over 12 months. 5 of these patients will be at low high of having coronary artery disease and 20 at high risk of coronary artery disease. patients will be recruited from those referred for clinical stress stress echocardiography.

You may qualify if:

  • Ability to give informed consent
  • age ≥18years and
  • confirmed inducible wall motion / perfusion abnormality on previous stress echocardiogram
  • known coronary artery disease - defined by presence of flow-limiting coronary stenosis(\>70% diameter stenosis) on coronary angiography.
  • patient who has been assessed as at low risk of having coronary heart disease

You may not qualify if:

  • Inability to undertake pharmacological stress, ie previously known intolerance to dipyridamole;
  • Moderate or Severe aortic or mitral regurgitation or severe mitral stenosis;
  • Significant pulmonary disease like severe COPD or pulmonary fibrosis;
  • Atrial fibrillation;
  • Inability to provide informed consent;
  • Pregnancy and lactation;
  • Known allergy to Sonovue
  • Patients with second and third degree heart block, unless they have a pacemaker fitted
  • Systolic BP \< 90
  • Known Myasthenia Gravis
  • Bronchial asthma
