Objective:

To assess the relationship between prediabetes, myocardial injury or stress, and heart failure risk in adults with hypertension.

Approach:

Key Findings:

• {'original': 'Patients with prediabetes and myocardial injury had a 4.20-fold higher risk of heart failure compared to normoglycemia without injury.', 'edited': 'Patients with prediabetes and myocardial injury had over ten times the risk of heart failure compared to normoglycemia without injury.'}

Interpretation:

Prediabetes amplifies the risk of heart failure in individuals with hypertension when combined with myocardial injury or stress.

Limitations:

• Observational nature of the study does not establish causality.
• Single fasting plasma glucose measurement may lead to misclassification of prediabetes.
• Lack of echocardiographic data limits assessment of cardiac structure and heart failure phenotype.

Conclusion:

Biomarkers significantly drive heart failure risk, with prediabetes acting as a clinically meaningful modifier that increases vulnerability to myocardial dysfunction.
