A Simple Way to Halve the Risk of Recurrent Heart Attack Identified 0 8

Individualized dosing of vitamin D3 may halve the risk of recurrent heart attacks in patients who have experienced a heart attack. This conclusion was reached by cardiologists at the Intermountain Health medical center, who presented the results of a large clinical study at the annual American Heart Association Scientific Sessions (AHA) 2025 conference in New Orleans.

The study involved 630 patients who had recently suffered a heart attack. Some received standard care, while others underwent 'personalized' therapy with regular monitoring of vitamin D levels in the blood and adjustments of the D3 dose to optimal values (above 40 ng/ml). This approach reduced the likelihood of a second heart attack by 50 percent without causing side effects.

The authors of the study noted that standard vitamin D supplements rarely provide significant benefits; however, with precise dose adjustments based on blood vitamin levels, the effect becomes substantial. They believe that personalized management of vitamin D could become a new direction in the prevention of cardiovascular diseases, especially considering that a deficiency of this substance is observed in most people worldwide.
