Study information

Primary study designInterventional
Study designRandomised controlled trial
Secondary study designRandomised controlled trial
Scientific title
Study objectivesTo study if the use of verapamil and adenosine will result in improved blood flow through the heart arteries, assessed by the TIMI frame count.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedUrological and Genital Diseases: Angiography and/or angioplasty
InterventionPatients undergoing coronary angiography with a view to urgent or emergency angioplasty will be consented and will be given a patient information leaflet. Patients will be randomised if their coronary arteries show evidence of the slow-flow phenomenon and all patients undergoing angiography and/or angioplasty in the setting of an acute coronary syndrome will also be randomised. Normal saline, verapamil or adenosine will be administered and pictures of the heart arteries will be taken. At the end of the procedure the TIMI frame count (number of picture frames required for the dye to travel from the top end of the artery to the bottom end) will be calculated.
Intervention typeDrug
PhaseNot Specified
Drug / device / biological / vaccine name(s)verapamil and adenosine
Primary outcome measure(s)

1. Improvement in TIMI frame count.
2. Post-procedural left ventricular function (measured by echocardiography).
3. Speed and extent of ST segment recovery.
4. Cardiac enzyme measurements.
