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.

Temporalis muscle thickness (TMT) moderately correlates with appendicular skeletal muscle mass (ASM) in healthy older adults. This suggests TMT, measured via MRI, may be a practical tool for diagnosing sarcopenia in Alzheimer's disease studies.

Area of Science:

  • Gerontology
  • Neurology
  • Radiology

Background:

  • Sarcopenia, an age-related loss of muscle strength and mass, is associated with dementia and Alzheimer's disease (AD).
  • Diagnosing sarcopenia typically involves appendicular skeletal muscle mass (ASM) measurements via DXA, which are not standard in AD research.
  • Temporalis muscle thickness (TMT) measured by MRI is a potential alternative biomarker for sarcopenia.

Purpose of the Study:

  • To evaluate the correlation between TMT and ASM in healthy older adults.
  • To determine if TMT can serve as a practical diagnostic tool for sarcopenia in AD studies.

Main Methods:

  • Retrospective analysis of healthy, cognitively unimpaired older adults from the Intense Physical Activity and Cognition study.
  • TMT measured from brain MRI; ASM calculated and adjusted for height squared.
  • Sarcopenia defined using 2019 European working group criteria; Pearson correlation used to assess TMT-ASM and TMT-age relationships.

Main Results:

  • 95 participants (mean age 69.1 years, 53% female) were analyzed; 11% had sarcopenia.
  • A moderate positive correlation was found between TMT and ASM (r=0.41).
  • TMT did not correlate with age but was significantly different between individuals with and without sarcopenia (p=0.004).

Conclusions:

  • TMT shows a moderate correlation with ASM in cognitively unimpaired older adults.
  • MRI-based TMT assessment may be a feasible method for sarcopenia diagnosis in AD research.
  • Further research is needed to explore TMT's relationship with clinical outcomes in AD patients.
