Acute Coronary Syndromes
Pathophysiology
The mechanism of COVID-19 cardiovascular injury has not been fully understood and is likely multifactorial.
- SARS-CoV-2 virus attaches to ACE 2 protein for ligand binding before entering the cell via receptor-mediated endocytosis.
- Based on single-cell RNA sequencing more than 7.5% of myocardial cells have positive ACE2 expression. This protein can mediate the entry of SARS-CoV-2 and result in direct cardiotoxicity.
- The cytokine release caused by the virus may lead to vascular inflammation, plaque instability, myocardial inflammation, a hypercoagulable state, or direct myocardial suppression.
Pathological changes:
- In the level of cardiac tissue: minimal change to interstitial inflammatory infiltration and myocyte necrosis
- In the level of vasculature: micro-thrombosis and vascular inflammation[1]
ST-Elevation MI (STEMI)
A US model from 9 major centers showed a 38% drop in total STEMI activations during the COVID-19 pandemic. There is a 40% reduction noted in Spain as well. there was also a delay between the first presentation to a medical encounter up to 318 min. This is important since COVID-19 can potentially be a cause of STEMI through microthrombi, cytokine storm, coronary spasm, or direct endothelial injury.[2]
- Potential etiologies for the reduction in STEMI PPCI activations:
- avoidance of medical care due to social distancing or concerns of contracting COVID-19 in the hospital
- STEMI misdiagnosis
- increased use of pharmacological reperfusion due to COVID-19
It is very important to realize if patients' anxiety is the reason behind decreasing the presentation of STEMI to U.S. hospitals.[3]
- Treatment of STEMI & COVID-19: The specific protocols for the treatment have been evolving. Early recommendations showed intravenous thrombolysis as first-line therapy for STEMI patients with confirmed COVID-19 since most hospitals do not have protected cardiac catheterization labs.[2]
Signs and Symptoms
The signs and symptoms of acute coronary syndrome include:[4]
- Substernal chest pain
- Occurs at rest or exertion
- Radiation to neck, jaw, left shoulder and left arm
- Aggravated by physical activity and emotional stress
- Relieved by rest, nitroglycerin or both
- Chest discomfort described crushing, squeezing, burning, choking, tightness or aching
- Dyspnea
- Diaphoresis
- Nausea and vomiting
- Fatigue
- Syncope
Treatment
In patients with ACS, and COVID-19 treatment should follow the guideline of the updated Society for Cardiovascular Angiography and Interventions guidelines.[5]

Overview
- COVID-19 patients with cardiovascular comorbidities have higher mortality.
- Hospitalized patients with COVID-19 and Cardiovascular disease seem to be more prevalent in both the USA and China. [1]
- In a case series with 187 patients who had confirmed COVID-19, 27.8% of patients had a myocardial injury, which caused cardiac dysfunction and arrhythmias. The result was significantly higher mortality among patients with myocardial injury.
- It seems to be advisable to triage patients with COVID-19 based on their underlying CVD for a more aggressive treatment plan.
- The mortality during hospitalization was shown to be 7.62% for patients without underlying CVD and normal TnT levels, 13.33% for those with underlying CVD and normal TnT levels, 37.50% for those without underlying CVD but elevated TnT levels, and 69.44% for those with underlying CVD and elevated TnTs.[6]
