Abstract

Insights

Sodium-glucose cotransport 2 receptor inhibitors (SGLT2i) may improve heart attack outcomes by up-regulating proteins involved in heme-scavenging and nitric oxide transport, potentially reducing infarct size.

Area of Science:

  • Cardiology
  • Proteomics
  • Pharmacology

Background:

  • Sodium-glucose cotransport 2 receptor inhibitors (SGLT2i) are known to improve cardiovascular outcomes post-myocardial infarction.
  • Limited research exists on the specific pathophysiological mechanisms influenced by SGLT2i prior to myocardial infarction.

Purpose of the Study:

  • To investigate differential protein regulation in patients with ST-segment elevation myocardial infarction (STEMI) who were taking SGLT2 inhibitors versus those who were not.
  • To identify specific protein markers associated with SGLT2 inhibitor use preceding STEMI.

Main Methods:

  • Blood samples were collected from STEMI patients between June 2021 and October 2023.
  • Propensity-matched pairs of diabetic patients on (SGLT2i+) and not on (SGLT2i-) SGLT2 inhibitors prior to STEMI were created.
  • Liquid chromatography-tandem mass spectrometry was used to identify differentially expressed proteins between the two groups.

Main Results:

  • Of 149 eligible diabetic STEMI patients, 33 propensity-matched pairs (SGLT2i+ vs. SGLT2i-) were analyzed.
  • Twenty-one differentially expressed proteins were identified between the groups.
  • Patients on SGLT2i+ showed a predominant up-regulation of proteins involved in heme-scavenging and nitric oxide transport compared to SGLT2i- patients.

Conclusions:

  • SGLT2 inhibitor use is associated with the up-regulation of heme-scavenging and nitric oxide-related proteins preceding STEMI.
  • This protein regulation may contribute to the observed reduction in infarct size and improved outcomes in heart failure post-myocardial infarction.

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...

Glucose Transporters01:27

Glucose Transporters

Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

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...

Secondary Active Transport01:55

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
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 Coronary Syndrome I: Introduction01:30

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...
