How should a COVID‑19 positive patient with ST‑segment elevation myocardial infarction be managed, including reperfusion strategy and staff protection measures?

Management of COVID-19 Positive STEMI Patients

Primary PCI remains the definitive reperfusion strategy for COVID-19 positive STEMI patients and should be performed within 120 minutes of first medical contact, with universal use of full PPE including N95 respirators, gowns, gloves, and face shields for all catheterization laboratory staff. 1

Initial Emergency Department Evaluation

Confirm True STEMI Diagnosis

• All STEMI patients must undergo initial evaluation in the ED before catheterization laboratory activation to exclude COVID-19-related STEMI mimics (myocarditis, stress cardiomyopathy) which are common in COVID-19 patients and would not benefit from reperfusion therapy 1
• Perform point-of-care ultrasound (POCUS) or transthoracic echocardiography to assess for wall motion abnormality consistent with ECG changes 1
• Consider coronary CT angiography when ST elevation and echocardiography findings are divergent 1
• Do not delay reperfusion for COVID-19 testing results—proceed based on clinical suspicion while awaiting confirmation 1

COVID-19 Screening and Risk Stratification

• Perform rapid COVID-19 testing if available, but never delay primary PCI for test results 1
• Place face mask on patient immediately to prevent droplet contamination during transport 1
• Intubate patients with respiratory compromise before arrival in catheterization laboratory to minimize aerosolization risk 1

Reperfusion Strategy Selection

At PCI-Capable Centers

Primary PCI is the preferred strategy for COVID-19 positive STEMI patients when performed within 120 minutes of first medical contact 1

Catheterization Laboratory Protocol

• Use dedicated COVID-19 catheterization laboratory stocked only with essential equipment 1
• All staff must wear PPE for aerosolized and droplet precautions: N95 respirator (with surgical mask overlay if reusing N95), gown, gloves, full face shield 1
• Consider powered air-purifying respirators (PAPRs) for high-risk aerosolization procedures 1
• Limit personnel to essential team members only 1
• Arrange ICU isolation bed before procedure 1
• Perform terminal cleaning requiring 4-6 hours after procedure 1

At Non-PCI Capable Hospitals

The decision between immediate transfer for primary PCI versus fibrinolysis depends on expected first medical contact to reperfusion time 1

Transfer for Primary PCI When:

• First medical contact to device time can be achieved within 120 minutes 1
• STEMI diagnosis is highly likely (not equivocal) 1
• Discussion between referral hospital and PCI center physicians confirms feasibility 1

Fibrinolysis First When:

• First medical contact to reperfusion expected to exceed 120 minutes 1
• Administer fibrinolytic therapy within 30 minutes of diagnosis 1
• Transfer all fibrinolysed patients to PCI center for angiography within 3-24 hours (pharmacoinvasive approach) 1
• Perform rescue PCI immediately if ST-segment resolution <50% at 60-90 minutes 1

Critical caveat: Regional STEMI systems must actively monitor transfer times during COVID-19 and adjust to fibrinolysis-first approach if pandemic-related delays develop 1

Special Populations

Cardiogenic Shock and Cardiac Arrest

• Patients with cardiogenic shock require primary PCI regardless of COVID-19 status—the mortality benefit (7.9% absolute decrease) substantially outweighs provider infection risk (2.3% absolute increase) 1, 2
• Resuscitated out-of-hospital cardiac arrest patients should be selectively considered for catheterization laboratory activation only with persistent ST elevation and wall motion abnormality on echocardiography 1
• Intubate in negative pressure room by anesthesia before catheterization laboratory arrival when possible 1
• Consider bedside mechanical circulatory support placement to decrease catheterization laboratory exposure 1

Futile Care Considerations

COVID-19 patients with severe ARDS or pneumonia requiring mechanical ventilation in the ICU with excessively high predicted mortality may warrant compassionate medical care rather than reperfusion therapy—this decision requires multidisciplinary discussion including patient/family wishes and local resource availability 1

Staff Protection Measures

Personal Protective Equipment Requirements

• Universal PPE for all STEMI cases during pandemic: N95 respirator, surgical gown, gloves, full face shield 1
• If reusing N95 masks between cases, wear additional surgical mask on top 1
• Proper PPE training and practice required for all physicians and catheterization laboratory staff 1

Procedural Precautions

• Highest risk for droplet spread: intubation, extubation, resuscitation 1
• Minimize exposures to essential team members during high-risk procedures 1
• Assume all patients are COVID-19 positive in high-prevalence areas (25-50% of infected patients are asymptomatic) 1

Post-Procedure Management

• Triage to ICU isolation bed for COVID-19 positive patients 1
• In uncomplicated cases without COVID-19, consider non-critical care bed to conserve ICU capacity 1
• Continue guideline-directed medical therapy per standard STEMI protocols 1

Critical Pitfalls to Avoid

• Never delay primary PCI for COVID-19 test results when STEMI diagnosis is clear 1
• Never perform fibrinolysis on equivocal STEMI cases without additional imaging—COVID-19 myocarditis and stress cardiomyopathy will not benefit and incur bleeding risk 1
• Never proceed without full PPE—even asymptomatic patients may be infected 1
• Never skip echocardiography in equivocal cases—STEMI mimics are common in COVID-19 1
• Do not let COVID-19 status alone determine reperfusion strategy—primary PCI remains superior when timely 1, 2
