An observational study in Myocardial Infarction, sponsored by Chiesi USA, Inc.. Active, not recruiting at 11 sites in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2025-06-13.
Sponsored by Chiesi USA, Inc. · Observational
The purpose of this registry is to address optimal platelet inhibition during the early management of MI patients prior to coronary angiography or CABG.
The CAMEO registry is a multicenter observational registry that will collect information on approximately 5,050 patients with NSTEMI or STEMI treated with cangrelor or an oral P2Y12 inhibitor into the registry.
Phase 1: Each site will abstract data from the medical record for the first 50 patients meeting the inclusion and exclusion criteria treated at the hospital within 4 months prior to study initiation or during the study period.
Phase 2: After Phase 1, all cangrelor-treated patients meeting the inclusion and exclusion criteria will be entered into the registry, and we will begin sampling non-cangrelor patients in a 2:1 cangrelor: non-cangrelor ratio (Phase 2) up to 3000 patients.
Phase 3: We will work with sites on a quality improvement initiative with the current sites to 1) continue enrollment of an additional 2,000 patients; 2) provide feedback reports to both the sites and operators about the use and administration of cangrelor to patients they are treating; 3) utilize a pharmacist-based group with representatives from each site to identify opportunities to improve use of cangrelor according to the established treatment strategy.
2,744 studies on the registry are indexed under Myocardial Infarction; 418 are open to participants now.
This study's enrollment of 5,050 is above the median of 500 across 983 observational studies indexed under Myocardial Infarction.

≥ 18 years of age and underwent coronary angiography for a STEMI or NSTEMI.
Phase 1 Inclusion Criteria:
For the first 50 patients at each participating site, consecutive patients are entered in the registry if they are ≥ 18 years of age, underwent coronary angiography for a STEMI or NSTEMI, and received cangrelor at any time during the hospitalization or an oral P2Y12 inhibitor during his/her first 48 hours of the hospitalization for MI.
Phase 2 Inclusion Criteria:
Subsequent patients are eligible to be entered in the registry if they are ≥ 18 years of age and underwent coronary angiography for a STEMI or NSTEMI and meet at least 1 of the following criteria:
The patient was hospitalized for STEMI and met one of the following inclusion criteria:
OR
The patient was hospitalized for NSTEMI and met one of the following inclusion criteria:
Exclusion Criteria: If the patient does not meet the inclusion criteria for either Phase.
Phase 3 Eligibility Criteria:
The Phase 3 portion of the CAMEO registry will focus on launching local site quality improvement initiatives with the goal of optimizing cangrelor usage according to FDA-approved established treatment strategy. Enrollment for the registry will be extended for an additional two years to include an additional 2,000 patients in this phase of the registry. The inclusion criteria of these patients will be the same as in Phase 2 (see section 3.3.2). We will also capture which patients are cared for at each site by individual operators. Operator-level data will be de-identified, and each operator will be assigned an operator ID. Sites will be asked to maintain a crosswalk for operator ID, and complete an operator characteristics survey. The operator characteristics survey will ask questions around age, sex, and other relevant operator characteristics, and will be used in the analysis phase in aggregate. Operators will not be directly identified and the analytics center will not have access to the crosswalk, which will be maintained at the site.
We will identify a pharmacist representative at each site to form a pharmacist-based group who meets monthly to identify strategies to improve processes at each site and to improve use of cangrelor in the MI population according to the established treatment strategy. We will present quarterly feedback reports to the sites that include data regarding the use of cangrelor according to the following parameters: 1) administration of both a bolus and infusion; 2) appropriate timing between infusion and initiation of oral PY212 inhibitor therapy; 3) and administration of the infusion based on clinical trial data and dose package labeling for patients who are able to be transitioned to oral P2Y12 inhibitor therapy shortly after PCI.
Patients in the registry will be 18 years of age or older and underwent coronary angiography for a ST-elevation myocardial infarction (STEMI) or NSTEMI Non-ST-elevation myocardial infarction
The number of Antiplatelet medications used during hospitalization
Antiplatelet use, including switching and discontinuation will be measured by medical record report. The medical record report will include medication start and stop dates and times.
Time frame: The time frame is hospitalization through discharge, approximately 3 days
Number of bleeding events during hospitalization as measured by medical record report
Bleeding event entered from the medical record report.
Time frame: The time frame is hospitalization, up to 7 days post discharge
Plan to share: No — There is not a current plan to share IPD.
