Coronary artery bypass graft (CABG) surgery, or simply bypass surgery, is a common procedure to improve blood flow to the heart when someone has severe coronary artery disease (CAD). CAD occurs when plaque builds up inside the coronary arteries, limiting the flow of oxygen-rich blood to the heart. CABG creates new pathways for blood to flow around the blocked arteries.
Testosterone, the primary male sex hormone, influences many bodily functions, including cardiovascular health. It plays a role in muscle mass, bone density, red blood cell production, and even mood regulation. But what is its role after bypass surgery?
Lowered testosterone levels are common in men with CAD. However, the relationship between testosterone levels and cardiovascular outcomes after CABG is complex and not completely clear. Previous research has provided conflicting findings regarding testosterone replacement therapy (TRT) and cardiovascular risk. Some studies suggest potential benefits, while others raise concerns about potential harm.
In this article, we’ll explore the relationship between testosterone and cardiovascular health in men following bypass surgery. We’ll discuss the potential risks and benefits of TRT and examine the current understanding of this complex issue.
