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.
    • 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]
  • 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.[2]

Classification

Myocardial infarction may be classified according to two subtypes:

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.[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]

  • 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.[3]

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[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]

Differentiating Myocardial infarction from other Diseases

Differentiating ST Elevation Myocardial Infarction from other Diseases
Differentiating Unstable Angina/Non-ST Elevation Myocardial Infarction from other Disorders

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]

Risk Factors

Diagnosis

History and Symptoms

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]
