Study design	Randomised, active controlled, parallel group trial
Primary study design	Interventional
Secondary study design	Randomised controlled trial
Study setting(s)	Hospital
Study type	Treatment
Scientific title	Effectiveness of thrombus aspiration compared to balloon angioplasty on myocardial reperfusion during percutaneous coronary intervention in acute myocardial infarction
Study acronym	TAPAS
Study objectives	Thrombus aspiration compared to balloon angioplasty will improve myocardial reperfusion during primary percutaneous coronary intervention.
Ethics approval(s)	Ethics approval received from the local ethics committee.
Health condition(s) or problem(s) studied	Myocardial infarction
Intervention	Thrombus aspiration compared to conventional balloon angioplasty during primary percutaneous coronary intervention. Patients are assigned to treatment with thrombus aspiration with the 6F Export Aspiration Catheter (Medtronic Corporation, Santa Rosa, California, USA) or to balloon angioplasty before stent implantation in the infarct related artery.
Intervention type	Other
Primary outcome measure	Angiographic myocardial blush grade of less than two
Secondary outcome measures	1. Enzymatic infarct size 2. ST-segment elevation resolution 3. Persistent ST-segment elevation 4. Post-procedural distal embolisation 5. Major adverse cardiac events at 30 days and one year
Overall study start date	01/01/2005
Completion date	01/01/2007

Participant type(s)	Patient
Age group	Adult
Sex	Both
Target number of participants	1080
Key inclusion criteria	1. A diagnosis of acute myocardial infarction (MI) defined by chest pain suggestive for myocardial ischaemia for at least 30 minutes, with a time from onset of symptoms of less than 12 hours, before hospital admission 2.
