Here is what the page “Low and High Testosterone Both Linked to Irregular Heartbeat, Study Finds” contains. A new study reveals that both low and high testosterone levels are associated with an increased risk of atrial fibrillation, a common irregular heartbeat that can lead to serious complications like stroke and heart failure. The research, which analyzed data from over 170,000 men, found a U-shaped relationship: men with the lowest and highest testosterone levels had significantly higher odds of developing the condition compared to those in the middle range.
Specifically, men with testosterone below 250 ng/dL had a 30% higher risk, while those above 650 ng/dL had a 20% higher risk, relative to men with levels between 350 and 450 ng/dL. These findings challenge the notion that simply boosting testosterone is always beneficial for heart health and underscore the importance of maintaining hormonal balance.
