Details and patient eligibility

About

Study objective is the evaluation of safety and efficacy at 12 months of the combination treatment of bare metal Stent plus Paclitaxel Eluting Balloon vs drug eluting stent in patients with ST-elevation myocardial infarction with less than 12 hours of evolution.

Full description

This is a multicenter, prospective, randomized, open study

After the permeabilization of the clinical event responsible artery patients will be randomized in a 1:1 ratio to one of the following treatment groups:

Group 1: insertion of a bare metal stent with post-dilatation with a paclitaxel eluting balloon (Pantera Lux ®)

Group 2: insertion of a drug elution stent

Patients (or their legal representative) must sign the consent before randomization.

Patients will be monitored 30 days after surgery, at 6 and 12 months.

The primary efficacy endpoint is Target Vessel Failure (TVF) at 12 months

This study will involve patients over 18 years old with STEMI, or new left bundle branch block or posterior AMI (ECG) that occur within 12 hours of onset of symptoms.

A total of 516 patients will be included.

Inclusion criteria

Patients aged equal or older than 18 years.
Acute myocardial infarction (AMI) within 12 hours of evolution (from the onset of symptoms) systolic time elevation of at least 1 mm (recorded in two or more contiguous leads), new left bundle branch block, or true posterior infarction.
Patients candidates for primary angioplasty as medical criteria
Written informed consent according to International Conference on Harmonization / Guide Clinical Practice and local legislation, obtained before any study procedure.
Diameter vascular coronary artery to treat between 2 mm and 4 mm.
Patients with 85-100% stenosis and TIMI Score (Thrombolysis In Myocardial Infarction) of 0-I.

Exclusion criteria

Patients who refuse to participate in the study
Cardiogenic shock (defined as systolic blood pressure less than 80 mm Hg for more than 30 minutes or need for vasopressors or intra-aortic balloon counterpulsation)
Concomitant diseases associated with a life expectancy of less than one year
Angiographic variables:
- Trunk unprotected
- Branching (side branch greater than 2.5 mm)
- Sinus tachycardia segment elevation myocardial infarction thrombosis secondary to stent
- If more than one stent to treat a single segment (overlapping stents)
- Patient candidate for surgical revascularization within 30 days
- Stenosis of greater than 30 mm in length (corresponding with the ball longer available)
- More severe stenosis in the same artery in which is expected to be addressed in the next 9 months
Women at childbearing age, where there is the possibility of pregnancy during the first year of follow-up, or nursing.
Any clinical condition, which in the opinion of the investigator, is considered clinically significant as to participate in the study.
Subjects who are participating in any study drug or medical.
Individuals who show inability to follow instructions or help during the course of the study.
Bleeding diathesis or other disorders such as gastrointestinal ulceration or cerebral circulatory disorders, restricting the use of treatments platelet aggregation inhibitors and anticoagulants.
Patients with an ejection fraction <30% (if known).
Allergy or hypersensitivity to paclitaxel intolerance, or compounds structurally related to the Butyryl tri-n-hexyl citrate (BTHC) matrix of administration.
Severe allergy to contrast media.
Coronary artery spasm in the absence of significant stenosis.
