Beta-Blockers Are Useless,  

and 

Sometimes Risky, for Most Cardiac Patients

Story at-a-glance

• Beta-blockers offer no survival benefit for most heart attack patients with normal heart function, even though they’re still widely prescribed

• Women face higher risks on beta-blockers, including nearly double the risk of death when given higher doses, while men show no measurable harm or benefit
• Side effects such as fatigue, dizziness, depression, and sexual dysfunction often burden patients without providing meaningful protection
• The real root of heart disease lies in damaged mitochondria, which are overwhelmed by linoleic acid (LA) from vegetable oils found in most processed foods
• You can protect your heart by reducing LA, eating the right kinds of carbohydrates, walking daily, getting safe sunlight, and tracking your HOMA-IR score.
