Treatment with Capsinoids Promotes Impaired Cardiomyocyte Contractility in Obesity without Positively Modulating...

Area of Science:

• Nutritional Science
• Cardiology
• Obesity Research

Background:

• Capsinoids (Cap) are bioactive compounds with thermogenic properties.
• Potential benefits for physiological changes, digestion, and fat loss in obesity.
• Limited understanding of capsinoid effects on cardiac tissue.

Purpose of the Study:

• Investigate chronic capsinoid administration effects.
• Assess cardiac contractility and morphology in obese rats.
• Utilize a high-fat diet (HFD) induced obesity model.

Main Methods:

• Male Wistar rats fed standard diet (SD) or HFD for 19 weeks.
• Groups: Control (C), Obese (Ob), Obese + capsinoids (ObCap).
• ObCap group received capsinoids (10 mg/kg) via gavage; cardiac evaluations performed.

Main Results:

• Obese rats showed increased fat deposits and adiposity, unaffected by capsinoids.
• Metabolic, hormonal, and lipid alterations observed between Ob and ObCap groups.
• Capsinoid treatment reduced fractional shortening and altered shortening time in obese rats.

Conclusions:

• Capsinoid treatment did not prevent obesity-related fat accumulation or metabolic dysfunction.
• Chronic capsinoid administration impaired cardiomyocyte contractility.
• Capsinoids may negatively impact cardiac function in obesity.
