Blood Studies for Cardiovascular System I: Cardiac Biomarkers01:20

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

1.2K
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...

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...

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...

Coronary Artery Disease II: Pathophysiology01:26

Coronary Artery Disease II: Pathophysiology

1.1K
Coronary Artery Disease (CAD) originates from a series of events that impair the function of coronary arteries, the blood vessels responsible for delivering oxygen-rich blood to the heart muscle. The pathophysiology of CAD is closely linked to atherosclerosis, a chronic inflammatory and lipid-driven condition affecting the vascular endothelium.1. Endothelial DamageThe process begins with damage to the vascular endothelium, which serves as a protective barrier between the blood and the vessel...

Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations

943
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Area of Science:

  • Cardiology
  • Vascular Biology
  • Biomarker Discovery

Background:

  • Myocardial infarction (MI) is a major cause of death, with rising incidence in younger populations.
  • Collateral coronary circulation, vital post-MI, develops via angiogenesis and arteriogenesis.
  • Current biomarkers for MI and angiogenesis lack association with arteriogenesis, hindering assessment of collateral development.

Purpose of the Study:

  • To review key biomarkers for collateral coronary arteriogenesis post-MI.
  • To identify early arteriogenesis biomarkers for assessing collateral circulation.
  • To inform timely therapeutic strategies following myocardial infarction.

Main Methods:

  • Literature review focusing on biomarkers of myocardial infarction, angiogenesis, and arteriogenesis.
  • Synthesis of existing knowledge on collateral vessel development pathways.
  • Analysis of biomarker relevance in the early post-MI phase.

Main Results:

  • Established biomarkers for MI and angiogenesis exist.
  • Arteriogenesis biomarkers are needed to fully assess collateral coronary circulation.
  • Specific early arteriogenesis biomarkers can be identified.

Conclusions:

  • Biomarkers for collateral coronary arteriogenesis are essential for evaluating post-MI collateral function.
  • Identifying these biomarkers can guide optimal therapeutic interventions.
  • Further research into specific arteriogenesis biomarkers is warranted.
