Discussion

Experimental model reveals cardiac dysfunction and lethal arrhythmia in metabolic syndrome rats, indicating altered β-adrenergic response.

Metabolic syndrome is associated with cardiac dysfunction and an increased risk of lethal arrhythmia.
Cardiac output and ejection fraction were significantly reduced in metabolic syndrome rats, indicating impaired cardiac function.
Analysis involved pressure-volume loops and biochemical assessments of the β-adrenergic system, revealing important changes in protein levels.
Findings suggest targeting metabolic syndrome could mitigate its progression to severe cardiac complications.

Sánchez-Hernández et al. (2025) studied this question.
