Blood Studies for Cardiovascular System I: Cardiac Biomarkers

749
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...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

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...

Summary
This summary is machine-generated.

Eye-tracking reveals that individuals with apathy exhibit more exploratory eye movements, challenging previous assumptions. This behavioral biomarker could improve apathy assessment in neurocognitive disorders.

Area of Science:

  • Neuroscience
  • Ophthalmology
  • Psychiatry

Background:

  • Apathy is a common neuropsychiatric symptom in Neurocognitive Disorders (NCD).
  • Objective behavioral biomarkers are needed to complement traditional apathy assessments.
  • Eye-tracking offers potential for quantifying exploratory behaviors relevant to apathy.

Purpose of the Study:

  • To investigate the utility of eye-tracking in assessing apathy in individuals with Mild NCD.
  • To explore differences in eye movement patterns between apathetic and non-apathetic individuals.

Main Methods:

  • 20 participants with Mild NCD and 18 with subjective cognitive decline viewed videos and used an interactive application.
  • Eye movements were recorded using a Tobii eye-tracker.
  • Apathy was assessed using standardized criteria and self-report measures, alongside comprehensive neuropsychological testing.

Main Results:

  • Apathetic participants showed increased fixations and saccades with shorter fixation durations.
  • Findings suggest a less organized exploratory pattern in apathetic individuals during visual tasks.
  • Correlations with neuropsychological data are being analyzed to link eye-tracking patterns with executive functions.

Conclusions:

  • Eye-tracking of image and video exploration provides complementary insights into apathy.
  • This method may enhance the understanding and clinical assessment of apathy in NCD.
  • Behavioral quantification through eye-tracking offers a novel approach to studying apathy mechanisms.
