Insights

Two hypertensive disorder of pregnancy (HDP)-related peptides, P-2091 and P-2378, correlate with diff-CAVI, an indicator of leg ischemia in lower extremity arterial disease (LEAD) patients. These peptides may serve as novel biomarkers for assessing leg ischemia severity in LEAD.

Area of Science:

  • Vascular Medicine
  • Biomarker Discovery
  • Cardiovascular Research

Background:

  • Cardio-ankle vascular index (CAVI) measures arterial stiffness, independent of blood pressure.
  • The difference in CAVI between legs (diff-CAVI) is a potential indicator for leg ischemia in lower extremity arterial disease (LEAD).
  • Hypertensive disorders of pregnancy (HDP)-related peptides are investigated as potential biomarkers for leg ischemia.

Purpose of the Study:

  • To investigate the relationship between diff-CAVI and serum levels of seven HDP-related peptides in LEAD patients.
  • To determine if HDP-related peptides can serve as biomarkers for leg ischemia in LEAD.

Main Methods:

  • 165 outpatients with LEAD receiving medication therapy were studied.
  • Serum levels of seven HDP-related peptides were measured using mass spectrometry.
  • Correlations between diff-CAVI and peptide levels were analyzed, including multivariate analyses.

Main Results:

  • Peptides P-2091 and P-2378 showed significant positive correlations with diff-CAVI.
  • Higher tertiles of P-2091 and P-2378 were associated with significantly higher odds of large diff-CAVI (≥1.05).
  • These associations remained significant and independent of common risk factors in multivariate analyses.

Conclusions:

  • HDP-related peptides P-2091 and P-2378 are associated with diff-CAVI in LEAD patients.
  • These peptides show potential as useful indicators for leg ischemia in patients with LEAD.

Assessment of the Cardiovascular System III: Palpation

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists

Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...

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...

Hormonal Regulation01:33

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Pulse Assessment Sites

Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...
