B Vitamins may Help Angioplasty Patients
Patients who took folic acid and vitamins B6 and B12 were less likely to experience re-narrowing of their arteries after having angioplasty. And they were less likely to need repeat angioplasties and bypass operations one year later.
An initial study published last November showed that patients who took the vitamins for six months following angioplasty experienced a 16 percent rate of restenosis compared with 28 percent for those who took placebo (sugar pill). Researchers continued to follow the patients for six additional months
The vitamins appear to help lower the levels of homocysteine, which is an amino acid that has been related to heart attacks.
