We examined the impact of calcitriol, the active form of vitamin D, on heart attack recovery using a mouse model of myocardial infarction (MI). In our study, we treated mice that had suffered a MI with calcitriol and observed promising results.
Our findings revealed that calcitriol helped reverse negative effects on heart function and reduced cardiac remodeling after a heart attack. It also targeted the inflammatory response typically associated with MI, improving the survival of heart muscle cells and promoting their regeneration.
We discovered that calcitriol works by enhancing the activity of the Vitamin D receptor (VDR). This process not only interferes with inflammatory signals but also leads to positive changes at the genetic level, further supporting heart health after an MI. Overall, our study provides strong evidence of calcitriol's cardioprotective properties, making it a potential treatment avenue for better outcomes following a heart attack.

We explored the impact of 1,25-dihydroxyvitamin D3 (VD3) on heart health, particularly after an acute myocardial infarction (AMI). To investigate this, we used male C57/BL6J mice and conducted a series of experiments, comparing those treated with VD3 to control groups.
Our findings revealed that VD3 treated mice showed significant improvement in heart function following AMI. This treatment not only enhanced cardiac function parameters but also reduced inflammation and the extent of myocardial damage. There was a notable decline in inflammatory markers and a decrease in cell apoptosis, indicated by a rise in protective proteins and a fall in those that lead to cell death.
In our in vitro studies with cardiomyocytes, we observed that VD3 boosted autophagy markers, enhancing the body’s ability to manage damaged cells. It seemed to activate key pathways involved in cell survival and repair, specifically the PI3K/AKT/mTOR pathway. However, when we inhibited this pathway with 3-methyladenine, the benefits of VD3 were reversed, indicating a direct link between autophagy promotion and the protective effects of VD3.
In summary, our research indicates that VD3 can be a valuable ally in the fight against heart damage and inflammation after a heart attack, primarily by supporting cellular repair processes.

We explored the impact of vitamin D levels on heart attack severity by examining 77 patients who experienced ST-elevation myocardial infarction (STEMI). A key focus was to understand how vitamin D deficiency might relate to the amount of thrombus, or blood clots, present in coronary arteries.
The findings revealed that a striking 79.22% of patients had vitamin D levels below what is considered adequate (less than 20 ng/mL). Notably, those with mild thrombus loads had higher vitamin D levels compared to those classified with severe thrombus loads, indicating a clear connection.
Furthermore, we discovered a negative correlation between vitamin D levels and the severity of thrombus. The lower the vitamin D levels, the higher the thrombus burden and the post-procedural TIMI frame count—essentially metrics that show how blood flows in the heart after treatment. This highlights that maintaining adequate vitamin D might be crucial for individuals at risk of severe heart complications.

We conducted a detailed study to uncover how vitamin D3, combined with exercise, affects recovery from heart attacks. Our research involved fifty-six male rats, some of which experienced a simulated heart attack, while others served as a control group.
The rats were then divided into several groups, receiving different treatments over eight weeks. We specifically looked at how vitamin D3 and aerobic-resistance training together impacted cardiac health, focusing on the important TGF-β1/Smad signaling pathway known to contribute to heart damage.
Our findings were quite revealing. We noticed that the combinations of vitamin D3 and exercise training significantly improved heart function. Specifically, those receiving both treatments showed higher heart ejection fractions and lower levels of TGF-β1 and collagen proteins, indicating less cardiac fibrosis. In contrast, the groups that only received one treatment did not show the same level of improvement.
This suggests that while vitamin D3 on its own was not studied in isolation, its combination with exercise led to better outcomes in heart attack recovery. Overall, these results indicate a promising role for vitamin D3 alongside exercise in supporting heart health after a heart attack.

Vitamin D and activity improve survival
We examined how vitamin D status and physical activity (PA) relate to long-term survival following a heart attack, also known as a myocardial infarction (MI). In our analysis of 4,837 MI patients, we measured the levels of vitamin D in their blood and assessed their physical activity using a reliable questionnaire.
Over an average follow-up of 14.4 years, we observed that higher vitamin D levels were linked to a significant reduction in both cardiovascular (CVD) and all-cause mortality. Specifically, patients with adequate vitamin D levels had about 37% lower risk of CVD-related deaths compared to those with lower levels. Additionally, engaging in more physical activity also correlated with a lower mortality risk.
Importantly, we found that those with low vitamin D levels and little to no physical activity faced a threefold increased risk of mortality compared to patients who had high vitamin D levels and were active. These findings suggest that both vitamin D and physical activity independently contribute to improving survival rates post-heart attack, regardless of other health factors.
Overall, this study underscores the importance of monitoring vitamin D levels and encouraging physical activity to enhance recovery and longevity after a heart attack.

We explored the effects of vitamin D3 on heart injury caused by ischemia/reperfusion (I/R), a common scenario during heart attacks. Using a laboratory model that mimicked this condition, we discovered that I/R treatment significantly harmed heart cells, leading to cell death and increased oxidative stress.
We observed that I/R conditions prompted an increase in mitochondrial fission and mitophagy—mechanisms that can worsen heart injury. However, when we introduced vitamin D3, it appeared to counteract these detrimental effects. Specifically, vitamin D3 decreased cell death and reduced harmful mitochondrial changes, suggesting a protective role for this vitamin.
In live mice undergoing I/R, we confirmed that vitamin D3 treatment effectively reduced not only apoptosis (cell death) but also the adverse changes in mitochondrial function and structure. Overall, our findings indicate that vitamin D3 could be an important ally in safeguarding the heart during a heart attack by maintaining the integrity of mitochondrial function.
