The Impact of Metabolic Syndrome on Heart Failure in Young Korean Population: A Nationwide Study

Area of Science:

• Cardiology
• Metabolic Health
• Public Health

Background:

• Limited data exist on metabolic syndrome's impact on heart failure (HF) in younger populations.
• Metabolic syndrome is a growing public health concern.
• Early identification of risk factors for HF is crucial.

Purpose of the Study:

• To investigate the association between metabolic syndrome and incident heart failure in individuals in their 40s.
• To quantify the risk of HF associated with metabolic syndrome and pre-metabolic syndrome.
• To identify other significant risk factors for HF in this demographic.

Main Methods:

• Utilized a large cohort from the Korean National Health Insurance Service (1,958,284 subjects).
• Classified subjects into normal, pre-metabolic syndrome (Pre-MetS), and metabolic syndrome (MetS) groups based on health screening data.
• Employed survival analysis to determine hazard ratios for HF development.

Main Results:

• Metabolic syndrome approximately doubled the risk of developing HF in both males (HR: 1.968) and females (HR: 2.398).
• Pre-metabolic syndrome also significantly increased HF risk (Males HR: 1.607, Females HR: 1.893).
• Acute myocardial infarction and low hemoglobin levels were identified as independent risk factors for HF.

Conclusions:

• Metabolic syndrome is a significant risk factor for heart failure in individuals in their 40s.
• Pre-metabolic syndrome also confers an elevated risk, suggesting a continuum of risk.
• Early intervention and management of metabolic abnormalities may be key in preventing HF.
