Heart and Vascular Clinical Trials

AID MI Study

PI: Samir Saba, MD
Research Coordinator: Eric Pasquantonio

The purpose of this research study is to determine and understand the clinical outcomes in patients following an AMI with cardiac monitoring using the Confirm RX Insertable Cardiac Monitor or Abbott equivalent commercially available insertable cardiac monitor. Your involvement in the trial will be for two years following randomization and the trial will enroll approximately 200 patients. 

• Looking for patients 18 years or older that have experienced AMI (STEMI and NSTEMI) and are expecting hospital discharge within 7 days of AMI. The patient must be willing to give written informed consent and receive ICM insertion within 21 days of index AMI.
• Follow-up will be done at 30 days, 90 days, 12 months, and 24 months after enrollment. All follow-up visits could be performed remotely by phone call and remote device interrogation (if applicable) or in person at the outpatient clinic.
• Questionnaires and surveys will be completed by the patient during the follow-up period. 
• There will be two treatment groups randomly assigned. 100 patients will be assigned to a control group (no device) and the other 100 patients will be assigned to receive the Insertable Cardiac Monitor.

The CATALYST Trial is studying the Amplatzer™ Amulet™ Left Atrial Appendage Occluder in patients with non-valvular atrial fibrillation who are either on a non-vitamin K antagonist oral anticoagulant (NOAC) blood thinner, or eligible to take a NOAC.

WHO CAN PARTICIPATE IN THE CATALYST TRIAL COMPARING LEFT ATRIAL APPENDAGE OCCLUSION TO NOAC THERAPY? Both men and women can participate.

You may qualify if: 

• You have been diagnosed with non-valvular atrial fibrillation and are at an increased risk for ischemic stroke 
• Your doctor believes you are eligible for NOAC therapy 
• You are willing and able to complete the study follow-up visits 
• You are willing to receive an Amulet Left Atrial Appendage Occluder if randomized to that therapy

Please reach out to Susan Sweeny, RN, for details at 412-864-1420 or sweenysm@upmc.edu.
