Abstract:
Traditional circulating biomarkers play a fundamental role in the diagnosis and prognosis of acute myocardial infarction (AMI). However, they have several limitations. microRNAs (miRs), a class of RNA molecules that do not encode proteins, function directly at the RNA level by inhibiting the translation of messenger RNAs. Due to their significant roles in disease development, they can be used as biomarkers. Accumulating evidence has revealed an attractive role of miRs as biomarkers of AMI and its associated symptoms, including vulnerable atherosclerotic plaques, and their role in disease diagnosis, platelet activation monitoring, and prognostic outcome prediction. This manuscript will highlight the recent updates regarding the involvement of miRs as biomarkers in AMI and emphasize their value in vulnerable atherosclerotic plaque prediction and monitoring of platelet activation.
Insights
MicroRNAs (miRs) show promise as novel biomarkers for acute myocardial infarction (AMI), offering advantages over traditional markers. They aid in predicting vulnerable plaques and monitoring platelet activation, improving AMI diagnosis and prognosis.
Area of Science:
- Biochemistry
- Molecular Biology
- Cardiology
Background:
- Traditional biomarkers for acute myocardial infarction (AMI) have limitations in diagnosis and prognosis.
- MicroRNAs (miRs), non-coding RNA molecules, regulate gene expression and are implicated in disease development.
Purpose of the Study:
- To review the emerging role of microRNAs (miRs) as biomarkers for acute myocardial infarction (AMI).
- To highlight the potential of miRs in predicting vulnerable atherosclerotic plaques and monitoring platelet activation.
Main Methods:
- Literature review of recent studies on microRNAs in AMI.
- Analysis of the diagnostic and prognostic value of miRs.
Main Results:

Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Blood Studies for Cardiovascular System I: Cardiac Biomarkers
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
