Overview
COVID-19 patients with cardiovascular comorbidities have higher mortality.Acute Myocardial Infarction is defined as an acute myocardial injury with clinical evidence of acute myocardial ischemia plus rise and/or fall of cardiac troponin values with at least one value above the 99th percentile upper reference limit and at least one of the following:Symptoms of myocardial ischemia including new ischemic ECG changes, development of pathological Q waves, imaging evidence of new loss of viable myocardium or new regional wall motion abnormality in a pattern consistent with an ischemic etiology. Identification of a coronary thrombus by angiography or autopsy (not for type 2 or 3 MI).[1]
Classification
Myocardial infarction may be classified according to two subtypes:
- Non ST Elevation Myocardial Infarction (non-STEMI)
- ST Elevation Myocardial Infarction (STEMI)
ST-Elevation Myocardial Infarction (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][3]
- 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.[4][1]
- 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]
Pathophysiology
The mechanism of COVID-19 cardiovascular injury has not been fully understood and is likely multifactorial.
- 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[5]
Causes
According to the Fourth Universal Definition of MI, there are two clinical classifications of the disease based on the causes:
- Type 1: MI caused by acute atherothrombotic CAD precipitated by atherosclerotic plaque disruption (rupture or erosion).
- Type 2: MI due to a mismatch between oxygen demand and supply
Most of the MIs associated with COVID-19 are type 2 indicating the causes to be the primary infection, hemodynamic disturbance, or respiratory deterioration.[1] [6]

Epidemiology and Demographics
- Hospitalized patients with COVID-19 and Cardiovascular disease seem to be more prevalent in both the USA and China. [5]
- Studies have shown reduction of incidence and hospitalization of acute MI during COVID-19 Pandemic.[7][4][8][9]
- A study in Italy showed up to a 49.4 percent reduction in admissions for acute MI to coronary care units from March 12th to 19th in 2020 compared to the equivalent time in 2019. [7]
Prognosis
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.[3]
Diagnosis
History and Symptoms
- 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[10]
Laboratory Findings
Unstable angina / non ST elevation myocardial infarction biomarkers
ST elevation myocardial infarction laboratory findings
Treatment
In patients with ACS, and COVID-19, treatment should follow the guidelines of the updated Society for Cardiovascular Angiography and Interventions.[5] [11]
