We explored the effects of folate, a form of vitamin B, on heart problems associated with TANGO2-deficiency disorder (TDD). This genetic condition can lead to dangerous heart rhythms that don’t respond well to standard treatments. To dive deeper into this issue, we established patient-derived heart cells, known as iPSC-CMs, to mimic the heart abnormalities seen in TDD.
In our observations, we found that high doses of folate almost completely eliminated arrhythmias in these heart cells. Interestingly, our clinical observations revealed that TDD patients taking multivitamins, particularly those high in B vitamins, experienced a significant reduction in cardiac crises. This suggests that folate may play a critical role in protecting against these life-threatening heart issues.
Our findings not only highlight the potential of folate as an effective treatment but also emphasize the importance of considering dietary supplements in managing cardiac risks in patients with TDD. Thus, we believe that boosting folate intake could offer a valuable strategy to enhance heart health in those affected by this disorder.

Maternal folic acid reduces CHD riskAssociation of maternal folic acid supplementation and offspring MTRR gene polymorphism with congenital heart disease: a hospital-based case-control study in Han population.
Relevant findings support folic acid use.
We explored how maternal folic acid supplementation relates to congenital heart disease (CHD) in children. Through a case-control study involving 595 children with CHD and 605 healthy controls, we found that mothers taking folic acid significantly reduced the risk of CHD and its subtypes. Notably, variations in the MTRR gene among offspring were linked to higher CHD risks, but maternal folic acid appeared to mitigate some of this risk. While results are promising, further research with larger samples is essential to fully understand these findings.

We explored the potential benefits of folic acid in treating dangerous heart rhythm problems linked to TANGO2-deficiency disorder (TDD). By creating patient-derived heart cell models, we observed that high doses of folate significantly reduced these arrhythmias. Additionally, clinical studies indicated that taking multivitamins, particularly those rich in B complex, lowered the chance of heart crises in TDD patients. Together, these findings suggest that B vitamins, including folate, could be vital in managing severe heart complications associated with this rare genetic disorder.

Folic acid reduces CHD riskAssociation of maternal folic acid supplementation and offspring MTRR gene polymorphism with congenital heart disease: a hospital-based case-control study in Han population.
Study directly links folate to heart health
We conducted a case-control study to look into how maternal folic acid supplementation affects the risk of congenital heart disease (CHD) in children and whether genetic factors, specifically MTRR gene polymorphisms, play a role in this relationship.
Our research involved 595 children diagnosed with CHD and 605 healthy children. By using a multivariate logistic regression model, we were able to assess the impact of maternal folate intake and the offspring's genetic profiles on the likelihood of developing CHD and its various subtypes.
The findings were quite striking. We observed that children whose mothers took folic acid during pregnancy showed a significantly reduced risk of CHD. Specifically, this included notable reductions in certain types of heart defects such as atrial septal defect and ventricular septal defect. Interestingly, specific polymorphisms in the MTRR gene were also linked to an increased risk of CHD.
Most importantly, we found that when mothers supplemented with folic acid, it appeared to mitigate some of the risks associated with genetic variants in their children. However, we recognize the need for additional studies with larger populations and different designs to confirm these important findings.

Vitamin B12 helps heart recoveryVitamin B12 alleviates myocardial ischemia/reperfusion injury via the SIRT3/AMPK signaling pathway.
Directly addresses vitamin B12 effects
We explored how vitamin B12 can act as a safeguard against heart damage caused by ischemia/reperfusion (I/R) injury. In our study, we used a mouse model subjected to I/R injury by occluding the left anterior descending coronary artery, followed by 24 hours of reperfusion.
Our aim was to see if high doses of vitamin B12 could improve heart function and reduce damage. Through various evaluations, including echocardiography and biochemical methods, we revealed that vitamin B12 supplementation does indeed help. It mitigates oxidative stress and lowers levels of harmful reactive oxygen species.
Additionally, we found that B12 supplementation reduced cell apoptosis—essentially cell death—in heart tissues. This response was linked to the action of specific signaling pathways, particularly the SIRT3/AMPK pathway. However, we noted that these protective effects diminished when a SIRT3 inhibitor was introduced, indicating the importance of this pathway.
Moreover, RNA sequencing data showed that vitamin B12 also plays a role in reducing inflammation during I/R injury. Overall, our findings suggest that high doses of vitamin B12 might serve as an effective strategy for treating myocardial damage from I/R events, potentially paving the way for new therapies in heart health.
