Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Randomisation 1: Transradial approach to arterial access.
Both the femoral and the radial artery are routinely used as entry sites for coronary angiography and angioplasty. Although femoral artery access is more common, radial artery access is associated with reduced bleeding complications. The procedure may take 30minutes to 1 hour.

Randomisation 2: Ultrasound-guided access
The operator will use an ultrasound probe to guide the needle into the femoral/radial artery. The procedure may take 30minutes to 1 hour.

Comparator / control treatment
Randomisation 1: Transfemoral approach to arterial acess
Both the femoral and the radial artery are routinely used as entry sites for coronary angiography and angioplasty. Femoral artery access is the most commonly used. The procedure may take 30minutes to 1 hour.

Randomisation 2: Standard approach to access.
The operator will follow standard procedure (that is, manual access without ultrasound guidance) for arterial access. The procedure may take 30minutes to 1 hour.
Control group
Active

Outcomes
Primary outcome [1] 266676 0
Major Bleeding as defined by the ACUITY TRIAL. That is:

* A reduction in haemoglobin level of at least 4g/dL without an overt bleeding source or at least 3g/dL with such a source.
* Intracranial or intraocular bleeding.
* Haemorrhage at the access site requiring intervention.
* Retroperitoneal bleed.
* Presence of a haematoma of at least 5cm in diameter.
* Reoperation for bleeding, or
* Transfusion of a blood product.
Timepoint [1] 266676 0
1 week, 30 days
Secondary outcome [1] 276172 0
Vascular complications such as pseudoaneurysm, arteriovenous fistulas, compartment syndrome or limb ischemia resulting in the need for vascular surgery. This will be assessed 1 week after the procedure by a vascular surgeon using ultrasound.

There will be a 30 day follow-up via telephone.
Timepoint [1] 276172 0
1 week, 30 days
Secondary outcome [2] 276173 0
The composite endpoint of major adverse cardiovascular events (MACE), including death, myocardial infarction, urgent target lesion revascularisation and stroke
Timepoint [2] 276173 0
1 week, 30 days
Secondary outcome [3] 276174 0
Procedural failure, this is defined as the need to access a second site due to the inability to cannulate the randomised approach.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment using sealed envelopes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Our method of randomisation will include the use of opaque, sealed same-coloured envelopes. After completion of baseline evaluations and assessment of inclusion and exclusion criteria, the patient will be consented and randomized using an opaque, sealed envelope system. This will consist of a pre-arranged box containing 100 opaque, sealed same-coloured envelopes of equal numbers of radial and femoral options. After randomisation, the patient will be randomised a second time using another pre-arranged box containing 100 opaque, sealed same-coloured envelopes of equal numbers of ultrasound-guided and standard options. These envelopes will be randomly topped up. Randomisation will be defined as the time the opaque envelope is opened. An allocation number will be assigned to each qualifying patient and will allow identification of the patient throughout the study.

Summary
Brief summary
The purpose of this study is to determine which of two different approaches in accessing an artery, transfemoral (via the artery in the groin) or transradial (via the artery in the wrist), both of these are currently used in clinical practice, is least associated with bleeding and procedural related complications.

It will also determine whether using an ultrasound machine to guide the arterial access will reduce bleeding and other procedural related complications.
