Circulatory syndrome: an evolution of the metabolic syndrome concept!

Area of Science:

• Cardiology
• Metabolic Disorders
• Vascular Biology

Background:

• Metabolic syndrome is a useful but controversial construct for understanding cardiovascular risk factors.
• The limitations of metabolic syndrome highlight the critical role of the circulatory system and endothelium in organ function.
• Emerging cardiovascular disease markers necessitate a refined conceptual framework.

Purpose of the Study:

• To propose the "Circulatory Syndrome" as an evolution of the metabolic syndrome concept.
• To integrate recently identified cardiovascular disease markers with established risk factors.
• To provide a more comprehensive model for understanding cardiovascular disease pathogenesis.

Main Methods:

• The study conceptually refines the metabolic syndrome by incorporating new markers.
• It includes factors such as renal impairment, microalbuminuria, arterial stiffness, ventricular dysfunction, and anemia.
• Classic factors like hypertension, dyslipidemia, and abnormal glucose metabolism are retained.

Main Results:

• The Circulatory Syndrome integrates traditional metabolic risk factors with newer cardiovascular markers.
• It acknowledges the interaction of these markers with lifestyle factors (aging, obesity, diet, smoking, inactivity).
• Common pathways of inflammation, oxidative stress, and hypercoagulability are identified as leading to endothelial damage.

Conclusions:

• The Circulatory Syndrome offers a refined approach to understanding cardiovascular disease.
• It builds upon the metabolic syndrome by incorporating a broader range of clinically measurable markers.
• Further research is needed to fully elucidate the complex interactions within this syndrome and its link to cardiovascular disease.
