Study-Based Risk Analysis
Based on the Heart Failure 2025 study, individuals in the highest quartile (Q4) have a 2.71 times higher risk of incident heart failure compared to lower quartiles.

About Waist-to-Height Ratio
Waist-to-Height Ratio (WtHR) is calculated by dividing your waist circumference by your height. It's considered a reliable indicator of central adiposity (fat stored around the abdomen and internal organs).
According to the Heart Failure 2025 study, WtHR is a significant predictor of heart failure risk:
- WtHR below 0.5 is considered ideal
- Higher WtHR was associated with an increased risk of incident heart failure
- Individuals in the highest quartile (WtHR above 0.61) had 2.71 times higher risk
| WtHR Value | Risk Category |
|---|---|
| Less than 0.5 | Low Risk |
| 0.5 to 0.57 | Moderate Risk |
| 0.57 to 0.61 | High Risk |
| Above 0.61 | Very High Risk |
Values based on the Heart Failure 2025 study quartiles. The study population had a median WtHR of 0.57 (interquartile range: 0.52-0.61).
Study Details
Research presented at Heart Failure 2025 by Dr. Amra Jujic from Lund University, Malmö, Sweden, found that WtHR is a significant predictor of incident heart failure.
Key Findings:
- 132 heart failure events occurred during a median follow-up of 12.6 years
- Hazard ratio per one standard deviation increase in WtHR: 1.34 (95% CI: 1.12-1.61)
- Individuals in the highest quartile of WtHR had 2.71 times higher risk
- The association remained significant after adjusting for confounders
According to study co-author Dr. John Molvin, "Having a waist measurement that is less than half your height is ideal."
The researchers concluded that WtHR may be a better metric than BMI to identify patients with heart failure who could benefit from therapies for obesity.
