Vitamin B6 aids heart recoveryVitamin B6 allosterically activates AMPK to promote postischemic angiogenesis in mice.
We explored the potential of vitamin B6 (VB6) in promoting recovery after heart attacks, specifically its role in angiogenesis, which is the formation of new blood vessels. The study aimed to determine whether VB6 could help prevent cardiac dysfunction following acute myocardial infarction (AMI).
To assess the effects of VB6, we conducted both in vitro experiments, examining endothelial cell behavior, and in vivo tests using mice with heart attacks. We discovered that VB6 significantly enhanced cell migration and tubule formation in human umbilical vein endothelial cells, which are critical for blood vessel formation. This process was linked to increased activity of a protein called AMP-activated protein kinase (AMPK).
Interestingly, our findings showed that these beneficial effects of VB6 were reversed when we introduced AMPK inhibitors. This leads us to conclude that VB6 promotes heart recovery by activating AMPK, which in turn supports angiogenesis following AMI. In practical terms, long-term VB6 supplementation after heart attacks led to improved heart function and increased new blood vessel formation in mice, making this vitamin a promising candidate for heart recovery therapies.

Pyridoxamine improves post-MI outcomesPyridoxamine improves survival and limits cardiac dysfunction after MI.
We investigated the potential of pyridoxamine, a form of vitamin B6, to improve outcomes after a heart attack (myocardial infarction, or MI). In our study, we divided rats into three groups: one that suffered from MI, another that also received pyridoxamine, and a sham group for comparison.
Over the course of eight weeks, we observed how these treatments impacted heart function using echocardiography and hemodynamic assessments. Remarkably, we found that pyridoxamine not only enhanced survival rates post-heart attack but also significantly reduced harmful levels of advanced glycation end products (AGEs) – compounds that can lead to heart failure.
Specifically, rats treated with pyridoxamine exhibited lower left ventricular pressures and improved heart deformation parameters compared to untreated rats. This better heart function was linked to a decrease in collagen in heart tissue, especially around the damaged area, which is crucial because excess collagen can worsen heart stiffness.
Overall, our findings suggest that pyridoxamine could be a promising therapy for preventing detrimental heart changes following a heart attack, highlighting the value of targeting AGEs in treatment strategies.

Potential role of vitamin B6Potential Anti-Inflammatory Treatment of Ischemic Heart Disease.
We conducted a study to find out how vitamin B6, particularly in combination with other treatments, affects heart attack outcomes. Our research involved 80 participants who were monitored for various health markers over a year. We had an experimental group that received standard ischemic heart disease (IHD) treatment along with ampicillin, vitamin B complex, including B6, and other vitamins.
What we found is quite interesting. The treatment group showed a moderate improvement in the systolic function of the heart compared to those who didn’t receive vitamin B6 and additional treatments. Importantly, there was a significant reduction in major adverse cardiac events (MACE) for this group, highlighting a potential anti-inflammatory effect from the treatment regimen.
However, while vitamin B6 was part of this treatment package, we noted that it was challenging to assess its isolated impact on heart attack outcomes. This means that while we saw promising results, we can't definitively say how much of the benefit was directly due to vitamin B6 alone.

MTHFD1 polymorphism and heart attackB vitamin treatments modify the risk of myocardial infarction associated with a MTHFD1 polymorphism in patients with stable angina pectoris.
We explored the link between a specific genetic variation in the MTHFD1 gene and the risk of heart attacks, or acute myocardial infarctions (AMI), in patients with stable angina pectoris. Our team looked at data from 2,381 participants in a randomized trial where some were treated with vitamins B6, folic acid, and B12, while others received a placebo. Over an average follow-up period of 4.9 years, we noted that about 8.6% of the participants experienced a heart attack.
The results revealed that individuals with the MTHFD1 genetic variation had a significantly higher risk of experiencing an AMI, especially among those treated with vitamin B6 alone or with both vitamin B6 and folic acid/B12. In fact, those on combined vitamin treatment faced an even greater risk. However, for participants receiving either a placebo or folic acid/B12 alone, no substantial connection between the MTHFD1 variation and heart attack risk was observed.
Overall, our findings suggest that the risk associated with the MTHFD1 genotype is influenced by vitamin B6 treatment. This invites further investigation into how vitamins and nutritional factors may affect heart health and genetic predispositions.

Vitamin B6's effects inconclusiveEfficacy of vitamin and antioxidant supplements in prevention of cardiovascular disease: systematic review and meta-analysis of randomised controlled trials.
We explored the effectiveness of vitamin B6 in preventing heart attacks through a systematic review and meta-analysis of randomized controlled trials. This involved analyzing data from 50 studies that included nearly 300,000 participants. Our findings indicated that supplementation with vitamin B6 showed a small decrease in the risk of major cardiovascular events; however, this effect appeared primarily in studies deemed to be of lower quality.
Interestingly, while some studies suggested a potential link between vitamin B6 and a reduced risk of cardiovascular death, these benefits predominantly surfaced in trials supported by the pharmaceutical industry. In conclusion, it's important to highlight that there was no consistent evidence to support the use of vitamin B6 or other vitamin and antioxidant supplements in preventing heart disease overall. The results need careful interpretation, especially given that the beneficial effects reported were less convincing in high-quality trials.
Overall, our assessment suggests that while vitamin B6 might have some minor beneficial aspects regarding heart attack risk, the broader implications for using such supplements in heart disease prevention remain unclear and unsubstantiated.
