Insights

A high aspartate aminotransferase/alanine aminotransferase (AST/ALT) ratio in recovered COVID-19 patients indicates impaired cardiac function. This ratio may help identify individuals at risk for cardiac involvement, necessitating closer monitoring.

Area of Science:

  • Cardiology
  • Infectious Diseases
  • Biochemistry

Background:

  • COVID-19 can lead to cardiac complications even after recovery.
  • The AST/ALT ratio is a marker of liver function and inflammation.
  • Its role in post-COVID cardiac sequelae requires further investigation.

Purpose of the Study:

  • To evaluate the association between the AST/ALT ratio and cardiac parameters in recovered COVID-19 patients.
  • To determine if the AST/ALT ratio can predict cardiac involvement post-COVID-19.

Main Methods:

  • 87 hospitalized COVID-19 patients (non-ICU) were studied post-recovery.
  • Patients were divided into high and low AST/ALT ratio subgroups based on the median value.
  • Cardiac function was assessed using transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging (CMRI).

Main Results:

  • Higher AST/ALT ratio correlated with elevated inflammatory markers (CRP, D-dimer, fibrinogen).
  • Impaired left and right ventricular function (lower LVEF, TAPSE, S', FAC, RV stroke volume, RV ejection fraction; higher RV end-systolic volume) observed in high AST/ALT group.
  • Increased myocardial T1/T2 mapping signals and extracellular volume detected by CMRI in high AST/ALT group.

Conclusions:

  • An elevated AST/ALT ratio is linked to echocardiographic and CMRI-defined cardiac dysfunction after COVID-19 recovery.
  • AST/ALT ratio at admission may serve as a risk indicator for cardiac involvement in COVID-19.
  • Patients with high AST/ALT ratios may benefit from intensified cardiac monitoring.

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Acute Coronary Syndrome I: Introduction

Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
