Vitamin B12 shows no heart attack benefit
Urinary excretion of homocysteine thiolactone and the risk of acute myocardial infarction in coronary artery disease patients: the WENBIT trial.
Limited relevance due to findings.
In a recent study, we delved into the role of homocysteine thiolactone, a metabolite linked to heart disease, in predicting the risk of acute myocardial infarction (AMI). Conducted with a sizable group of 2049 patients suspected of having coronary artery disease (CAD), the trial was meticulously designed as a double-blind clinical intervention.
Participants were divided randomly into four distinct groups, receiving a combination of folic acid and other B vitamins or a placebo. Notably, we measured urinary levels of homocysteine thiolactone at different points throughout the study to draw correlations with heart attack incidents.
Our analysis revealed that while the homocysteine thiolactone/creatinine ratio was a significant predictor of AMI risk, there was no observable effect from the vitamin B treatments received by participants. This suggests that vitamin B12, when part of a group of B vitamins, did not independently influence the likelihood of having a heart attack.
Ultimately, we found that higher levels of homocysteine thiolactone correlated with a greater risk of AMI, but the combination of vitamin B treatments did not alter this outcome. This points to the potential of homocysteine thiolactone as an important marker in understanding cardiovascular health.

Vitamin B12 ineffective for heart attack
Homocysteine thiolactone contributes to the prognostic value of fibrin clot structure/function in coronary artery disease.
Combination therapy's impact unclear
We explored the role of vitamin B12 in relation to heart attacks by examining the effects of a combination therapy including B-vitamins and folate in patients with coronary artery disease (CAD). In a large-scale study involving nearly 2,000 participants, the researchers monitored how these vitamins impacted fibrin clot characteristics and the risk of heart attack over several years.
Surprisingly, our findings indicated that vitamin B12 alone, as part of the combination therapy, did not significantly influence heart attack risk or outcomes. Instead, other factors like homocysteine thiolactone and plasma cysteine emerged as key players in determining clot properties and predicting adverse outcomes.
While we noted that baseline clot lysis time and maximum absorbance were associated with higher risks of acute myocardial infarction and mortality, the treatment with B-vitamins did not alter these markers significantly. Thus, the lack of efficacy from vitamin B12 in this context raises important questions about its effectiveness in preventing heart attacks when administered with other nutrients.

Supports heart health
Excellent vitamins. I really respect Now Foods, so I chose their B-12. It’s affordable, with a large canister. The pink, cherry-flavoured lozenges are delightful. Vitamin B12 lowers homocysteine levels, reducing the risk of heart attacks. It also aids in producing choline, which helps combat poor dietary habits and liver issues, while participating in amino acid synthesis that boosts mental activity and positive emotions.

Improves heart function
I bought vitamin B12 for its crucial role in the body, especially in improving the nervous system and enhancing the absorption of macronutrients. It positively impacts heart muscle function and helps maintain blood pressure. I will update my review post-course.
