Hypothesis
Is there a graded association between the number of components of the metabolic syndrome and cardiac structural and functional abnormalities?
Conclusion
Increasing severity of metabolic syndrome was associated with increasingly compromised structure and function of the heart.
Supporting Evidence
- The metabolic syndrome was present in 19.7% of participants, more common in women.
- High blood pressure was the most prevalent component, affecting about 75% of participants.
- The prevalence of left ventricular diastolic dysfunction increased significantly with the number of metabolic syndrome features.
Takeaway
The more features of metabolic syndrome a person has, the more likely their heart structure and function are affected.
Methodology
A cross-sectional study was conducted on a random sample of the urban population of Porto aged 45 years or over, using structured interviews, ECG, and echocardiograms.
Potential Biases
Potential selection bias due to underrepresentation of advanced heart failure patients.
Limitations
The sample size was relatively small, which may lead to few outcomes in certain categories, and the cross-sectional design limits causal inference.
Participant Demographics
Participants were urban adults aged 45 years or older from Porto, Portugal.
