Insights

Four circulating biomarkers, including angiopoietin-2 (ANGPT2) and fibroblast growth factor 23 (FGF23), are elevated in patients with volume overload and predict mortality. These markers may offer new diagnostic insights for cardiac conditions.

Area of Science:

  • Cardiology
  • Biomarker Discovery
  • Vascular Biology

Background:

  • Emerging evidence suggests circulating biomarkers like angiopoietin-2 (ANGPT2), bone morphogenetic protein-10 (BMP10), fibroblast growth factor 23 (FGF23), and insulin-like growth factor-binding protein 7 (IGFBP7) are linked to adverse cardiac remodeling.
  • These biomarkers reflect distinct pathophysiological processes in the vasculature and heart, particularly in response to pressure or volume overload.

Purpose of the Study:

  • To investigate the association between ANGPT2, BMP10, FGF23, and IGFBP7 and the presence of hemodynamically significant pressure or volume overload.
  • To explore the relationship between these emerging biomarkers and adverse clinical outcomes, including all-cause mortality.

Main Methods:

  • An observational cohort study was conducted with 1506 outpatient cardiology patients.
  • Multivariable-adjusted regression models were employed to examine the relationship between the four biomarkers and pressure/volume overload.

Main Results:

  • Elevated levels of all four biomarkers were positively associated with significant volume overload.
  • FGF23 and NT-proBNP showed significant associations with pressure overload.
  • Higher concentrations of all biomarkers predicted all-cause mortality in patients with volume overload.

Conclusions:

  • Circulating biomarkers reflecting inflammation, fibrosis, and calcification pathways are elevated in patients with significant volume overload.
  • These biomarkers, especially when considered with NT-proBNP, warrant further investigation for targeted clinical applications due to their association with mortality.

Heart Failure II: Pathophysiology

Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

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...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

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...
