Association between Variability of Metabolic Risk Factors and Cardiometabolic Outcomes

Area of Science:

• Cardiology
• Metabolic Health
• Preventive Medicine

Background:

• Cardiovascular disease (CVD) remains a leading cause of mortality despite efforts to manage risk factors like glucose, cholesterol, and blood pressure.
• Residual risk persists in many patients even when key cardiometabolic factors are within target ranges.
• Emerging research suggests metabolic factor variability may contribute to this residual CVD risk.

Purpose of the Study:

• To review the existing literature on the association between metabolic factor variability and cardiovascular disease (CVD) risk.
• To explore potential biological mechanisms linking metabolic variability to CVD.
• To discuss potential therapeutic strategies for mitigating cardiometabolic risk factor variability.

Main Methods:

• Comprehensive literature search of clinical trials and cohort studies.
• Analysis of reported associations between metabolic parameter variability and CVD incidence.
• Synthesis of proposed pathophysiological mechanisms.

Main Results:

• Studies indicate a significant relationship between increased variability in metabolic factors (e.g., glucose, lipids) and higher CVD risk.
• Variability may reflect underlying physiological dysregulation contributing to endothelial dysfunction and atherosclerosis.
• Evidence suggests variability impacts CVD risk independently of average factor levels.

Conclusions:

• Metabolic factor variability is an important, underappreciated contributor to residual cardiovascular risk.
• Targeting metabolic variability may offer novel therapeutic avenues for CVD prevention.
• Further research is needed to elucidate mechanisms and develop targeted interventions.
