Human resistin in cardiovascular disease.
1National Research Laboratory for Cardiovascular Stem Cell Niche, Korea.
Summary
Human resistin, an adipokine, is increasingly recognized as an inflammatory mediator and biomarker for cardiovascular diseases like atherosclerosis and heart failure, rather than solely for obesity-related insulin resistance.
Area of Science:
- Biochemistry
- Cardiology
- Endocrinology
Background:
- Resistin, an adipokine, was initially proposed as a mediator of obesity-related insulin resistance in rodents.
- The role of resistin in human obesity and insulin resistance remains controversial due to species differences and conflicting epidemiologic data.
Purpose of the Study:
- To review recent evidence on the role of human resistin in cardiovascular diseases.
- To highlight resistin's function as an inflammatory mediator and biomarker in human cardiovascular conditions.
Main Methods:
- Literature review of recent human clinical studies and experimental data.
- Focus on studies investigating resistin's involvement in atherosclerosis and heart failure.
Main Results:
- Human resistin functions as an inflammatory mediator.
- Human resistin serves as a biomarker for cardiovascular diseases, particularly atherosclerosis and heart failure.
Conclusions:
- Recent human studies support resistin's role as an inflammatory mediator.
- Human resistin is a significant biomarker for cardiovascular diseases, warranting further investigation in this context.

01:19Blood 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...

01:27Psychoneuroimmunology: Cardiovascular Disease
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

01:20Vascular Resistance
Vascular resistance is a critical concept in understanding blood flow dynamics in the circulatory system. It refers to the resistance that blood encounters as it flows through the blood vessels. This resistance is a key factor in determining blood pressure and cardiac workload.
The primary determinants of vascular resistance are vessel diameter, blood viscosity, and vessel length. Among these, vessel diameter plays the most significant role due to the fourth power relationship described by...

01:30Coronary Artery Disease I: Introduction
Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
01:29Cardiomyopathy IV: Restrictive Cardiomyopathy
Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...
01:27Regulation of the Cardiovascular System
The regulation of the cardiovascular system allows the body to adapt to various demands and maintain homeostasis.
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
