Blood Studies for Cardiovascular System I: Cardiac Biomarkers01:20

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

516
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...

Area of Science:

  • Neuroscience
  • Public Health
  • Sociology

Background:

  • Discrimination is a social determinant of health.
  • Racial discrimination may contribute to health disparities in Alzheimer's disease (AD) and related dementias.
  • Associations between discrimination, vascular, and AD biomarkers may explain excess dementia risk in minoritized groups.

Purpose of the Study:

  • To investigate the relationship between racial discrimination and brain imaging biomarkers.
  • To examine if these associations differ across ethnoracial groups.

Main Methods:

  • Utilized data from the MESA prospective cohort study (n=6,814).
  • Assessed racial discrimination experiences and burden at baseline.
  • Collected brain MRI (n=1,372) and amyloid PET (n=422) data during follow-up exams.
  • Analyzed associations between discrimination and cerebral small vessel disease (white matter hyperintensities, cerebral microbleeds, enlarged perivascular spaces) and amyloid PET positivity, stratified by ethnoracial group.

Main Results:

  • Black and Hispanic participants reported higher rates of racial discrimination.
  • Racial discrimination was associated with enlarged perivascular spaces in Black and Hispanic participants, and white matter hyperintensities in Black and Hispanic participants.
  • Lifetime discrimination was linked to higher odds of cerebral microbleeds in Hispanic participants.
  • Higher burden of discrimination was associated with increased cerebral amyloid burden in Black participants.

Conclusions:

  • Lifetime racial discrimination and its burden are associated with brain imaging biomarkers related to cognitive function.
  • These associations are more pronounced within specific ethnoracial groups, underscoring the differential impact of discrimination on brain health.
