Hong kong launches study to track heart shock survival

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Diagnosis of acute myocardial infarction (AMI) with the ECG and/or biomarker evidence of S-T elevation myocardial infarction (STEMI) or non -S-T elevation myocardial infarction (NSTEMI) * Cardiogenic Shock is defined as presence of at least two of the following 1. Hypotension (systolic blood pressure ≤ 100 mmHg, or inotropes/vasopressors to maintain systolic blood pressure ≥ 100 mmHg) 2. Evidence of end organ perfusion: elevated serum lactate levels (venous or arterial), cool extremities, oliguria/anuria 3. Hemodynamic criteria represented by cardiac index of \<2.2 L/min/m² or a cardiac ≤ 0.6 watts * Patient is supported with a transvalvular MCS as the initial device (criteria for GCSI-eligible Cohort) * Patients undergo PCI within 12 hours of hospital presentation (criteria for GCSI-eligible Cohort) * Subject or legally designated representative (LDR) has provided written informed consent. For patients not able to provide consent, data collection will be conducted in retrospective manner with study consent waived. Exclusion Criteria: * Unwitnessed out of hospital cardiac arrest or any cardiac arrest in which return of spontaneous circulation (ROSC) is not achieved within 20 minutes * Patients demonstrate any signs of anoxic brain injury prior to the INDEX PCI (signs of anoxic injury include, posturing, seizures). * IABP placed prior to MCS (criteria for GCSI-eligible Cohort) * Septic, anaphylactic, hemorrhagic, and neurologic causes of shock * Non-ischemic causes of shock/hypotension (pulmonary embolism, pneumothorax, myocarditis, tamponade, etc.) * Active bleeding for which MCS in contraindicated * Recent major surgery for which MCS is contraindicated * Mechanical complication of AMI (acute ventricular septal defect (VSD) or acute papillary muscle rupture) * Known left ventricular thrombus for which MCS in contraindicated (criteria for GCSI-eligible Cohort) * Mechanical aortic prosthetic valve (criteria for GCSI-eligible Cohort) * Contraindication to intravenous systemic anticoagulation which precludes placement of MCS. Patients who fulfills all Eligibility Criteria would be recruited and considered GSCI-eligible. AMI-CS patients that did not use MCS, ie. Not fulfiliing both Inclusion Criteria 3, 4, would not be considered screen failure and would still be screened and recruited into HKCSI GCSI-ineligible cohort. Likewise, patients who meet any of Exclusion Criteria will not be GCSI-eligible. Specifically, patients who met exclusion criteria 3, 9, 10 only will be recruited into GCSI-ineligible cohort.
