Rationale: Compared with balloon angioplasty, implantation of bare metal stents (BMS) and drug eluting stents (DES) have shown to reduce repeat target lesion revascularization in primary percutaneous coronary intervention (PPCI). However, this did not result in a reduction of mortality or recurrent myocardial infarction. Furthermore, there are concerns of the occurrence of stent thrombosis. The PAPPA-pilot study, evaluating safety and feasibility of using a drug-coated balloon (DCB) only strategy in PPCI, showed good short- and long-term clinical results, with sustained safety and efficacy at 12 months follow-up. To date little is known about the long-term effects of this treatment modality in STEMI. Besides, angiographic follow-up is of great clinical importance by giving insight on the treated infarct lesion and to assess the functional angioplasty result. Objective: This randomized controlled, non-inferiority trial is mainly designed to prospectively assess the safety and efficacy of a CE-marked paclitaxel-eluting balloon only strategy vs. third generation DES in the setting of a ST-elevation myocardial infarction (STEMI).

Study design: This is a prospective, single center, non-inferiority, randomized controlled trial. Study population: All patients presenting with STEMI and suitable for PPCI. Intervention: PPCI will be performed according to current guidelines. After thrombus aspiration and pre-dilatation, randomization between a DCB only strategy (with bail-out stenting if indicated) and DES will be done by 1:1 ratio. Concomitant medication will be administered according current standards. Control coronary angiography, including measurement of the fractional flow reserve (FFR) of the treated lesion(s), will be performed after 9 months. Main study parameters/endpoints: The main study parameter is the fractional flow reserve at 9 months follow-up. Secondary study parameters include cardiac death, recurrent myocardial infarction in the target vessel area and ischemia driven target lesion revascularisation at 9 months.

Fractional flow reserve (FFR)
Fractional flow reserve is the ratio of mean coronary pressure distal of the treated lesion to mean aortic pressure during maximum hyperemia.
Time frame: At 9 months follow-up
Major adverse cardiac event (MACE)
1. Cardiac death (ARC); defined as any death in which a cardiac cause cannot be excluded. 2. Recurrent MI in the target vessel area. 3. Ischemia driven target lesion revascularization (PCI within 5 mm of the treated segment in case of balloon, or stent area borders in case of stent, or CABG of the target vessel).
Time frame: In-hospital, at 1 and 9 months follow-up and at 2, 3, 4 and 5 year follow-up.
Angiographic endpoint: iFR
Time frame: At 9 months follow-up.
ST-segment resolution
ST-segment resolution post-initial procedure at 90 minutes, defined as the ST-segment deviation resolution in only the single lead showing maximum deviation.
Time frame: 90 minutes after initial procedure
Non-coronary artery bypass grafting major bleeding
* Intracranial, intraocular, intra-articular or retroperitoneal bleeding * Access site bleed requiring intervention/surgery * Hematoma ≥ 5 cm * Hemoglobin (Hgb) ≥4 g/dL without an overt source * Hgb ≥3 g/dL with an overt source * Operation for bleeding * Any blood transfusions
Time frame: At 1 month follow-up
Stent thrombosis
* Definite or confirmed stent thrombosis: Angiographic confirmation of vessel occlusion or thrombus formation within, or adjacent to, the stented segment or proven stent thrombosis at autopsy. * Probable stent thrombosis: Unexplained death within 30 days or target vessel recurrent MI without angiographic confirmation. * Possible stent thrombosis: Unexplained death after 30 days.
