Linking Trajectories of Organ Dysfunction to Major Adverse Cardiovascular Events
Overview
Revise to clarify the distinction between clinical obesity and BMI-based categories.
Background
Obesity is a significant modifiable risk factor for cardiovascular disease, yet traditional BMI-based assessments often misclassify individuals' risk. This study highlights the importance of defining obesity not just by body size but also by the presence of organ dysfunction, which may enhance risk stratification for cardiovascular events.
Data Highlights
Obesity Classification
MACE Risk (aHR)
95% CI
No Obesity
2.03
1.96–2.11
Clinical Obesity
1.61
1.30–2.01
Underweight
1.83
1.62–2.07
Persistent Dysfunction
2.19
1.32–3.63
Key Findings
Clinical obesity is associated with a higher risk of MACE compared to no obesity.
Persistent organ dysfunction significantly increases MACE risk across both obesity definitions.
10-year cumulative incidence of MACE is approximately 24% in individuals with clinical obesity.
BMI-based categories showed a peak MACE risk in the overweight category (~20%).
Organ dysfunction trajectories provide a more nuanced understanding of cardiovascular risk than BMI alone.
Clinical Implications
Healthcare professionals should consider incorporating clinical definitions of obesity that account for organ dysfunction when assessing cardiovascular risk. This approach may lead to improved risk stratification and management strategies for patients with obesity.
Conclusion
The study underscores the importance of evaluating organ dysfunction trajectories in understanding cardiovascular risk associated with obesity. Clinically defined obesity may offer a more accurate framework for risk assessment than traditional BMI metrics.
Patients are mining Reddit and TikTok for symptom intel while you're not — and a small study calls it epistemic injustice. Different knowledge, mutually unrecognized. Maybe ask where they've been reading before you wave it off as anecdote.
