We examined the connection between dietary magnesium and cardiovascular disease, focusing on how magnesium intake or serum levels relate to heart health. Over the last couple of decades, numerous studies have shown that low magnesium levels are associated with several heart-related issues, including high blood pressure, heart attacks, and even heart failure.
Our insights reveal that even mild or moderate magnesium deficiencies can trigger physiological and metabolic changes that may heighten cardiovascular risks. When magnesium levels are insufficient, we see a rise in inflammation, oxidative stress, and issues with how fats are processed in the body, which can lead to serious heart problems.
Furthermore, we noted that many individuals often consume less magnesium than what is recommended, particularly those who do not regularly eat whole grains, legumes, or green vegetables. This widespread lack of magnesium is concerning, as it could be a significant factor influencing heart disease in the general population.

Magnesium may help arterial health
Mitigation of arteriosclerosis through transcriptional regulation of ferroptosis and lipid metabolism by magnesium.
We investigated how magnesium impacts cardiovascular health, particularly its role in a condition known as arteriosclerosis. This disease can lead to serious heart complications, but recent studies revealed magnesium's potential benefits.
In a series of experiments involving human cells and animal models, we discovered that magnesium effectively reduces a process called ferroptosis, which is linked to the progression of arteriosclerosis. It appears that magnesium ions play a vital role by preventing certain proteins from breaking down. This action promotes the expression of protective proteins while reducing harmful components that contribute to the disease.
Notably, our animal tests highlighted that biodegradable magnesium stents not only hinder ferroptosis but also slow down the advancement of arteriosclerosis. This suggests that magnesium-based treatments could offer a promising avenue for combating cardiovascular diseases effectively.

Zinc counters heart cell injury
Zn protects H9C2 cardiomyocytes by alleviating MAMs-associated apoptosis and calcium signaling dysregulation.
We set out to investigate how zinc might help protect heart cells from damage caused by a lack of blood flow, known as myocardial ischemia-reperfusion injury (MIRI). Using H9C2 cells, which are derived from rat heart tissue, we simulated this injury by depriving these cells of oxygen and then reintroducing it while treating them with zinc.
Through this process, we found that zinc treatment significantly increased cell viability compared to those that did not receive zinc. Cells exposed to ischemia showed typical signs of trauma, like heightened levels of apoptosis—or programmed cell death—and calcium overload, which can further damage cells.
Interestingly, zinc seemed to tackle these issues by lowering the levels of certain proteins related to cell death. It also played a role in regulating calcium levels by interacting with various cellular pathways. In fact, when we silenced specific proteins involved in these pathways, the protective benefits of zinc were even more pronounced.
Our findings suggest that zinc can relieve the harmful effects of ischemia by mitigating cell death and regulating calcium overload, which offers hope for future treatments for heart-related conditions impacted by blood flow interruptions.

Frequently Asked Questions
Cardiovascular disease (CVD) is a broad term that encompasses a range of heart and blood vessel disorders. This can include conditions such as coronary artery disease, which leads to heart attacks; cerebrovascular disease that results in strokes; and peripheral artery disease affecting blood flow to the limbs. The key risk factors for CVD often include high blood pressure, high cholesterol, obesity, smoking, a sedentary lifestyle, and diabetes. By identifying and managing these risk factors, individuals can significantly reduce their likelihood of developing cardiovascular problems.
Prevention and treatment strategies often involve lifestyle modifications such as adopting a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins, alongside engaging in regular physical activity. In some cases, medications might be necessary to control blood pressure or cholesterol levels. Regular check-ups with a healthcare provider are essential for monitoring heart health, especially for individuals with a family history of CVD. Understanding the signs and symptoms of cardiovascular issues—like chest pain, shortness of breath, or fatigue—can help in seeking timely medical attention, ultimately leading to better outcomes.
Calcium magnesium refers to a dietary supplement that combines two essential minerals, calcium and magnesium, which play critical roles in maintaining various bodily functions. Calcium is vital for building and maintaining strong bones and teeth, while magnesium supports muscle function, energy production, and the regulation of calcium levels in the body. Together, these minerals work synergistically to promote overall health, particularly in areas such as bone density, cardiovascular health, and muscle function.
Supplements that contain both calcium and magnesium can be particularly beneficial for individuals who may be deficient in these minerals due to dietary restrictions or health conditions. They are available in various forms, including tablets, capsules, and powders. When considering a calcium magnesium supplement, it's essential to choose a product with the right ratio of these minerals, as well as other supporting vitamins and minerals like vitamin D, which enhances calcium absorption.

Magnesium's impact on HFpEF mortality
Propensity score matched cohort study on magnesium supplementation and mortality in critically ill patients with HFpEF.
We explored how magnesium supplementation affects mortality rates in patients with heart failure with preserved ejection fraction (HFpEF), a subset of heart failure where treatment options are limited. The study analyzed data from the MIMIC-IV database, focusing on patients from 2008 to 2019. Using a technique called propensity score matching, we aimed to create a balanced comparison between those who received magnesium supplements and those who did not.
Our primary focus was on the 28-day all-cause mortality rate, along with secondary analyses of ICU stays, one-year mortality, and overall hospitalization duration. In total, we evaluated 1,970 patients, splitting them evenly between the magnesium and non-magnesium groups. The outcomes were striking: magnesium intake was associated with a significant reduction in mortality within the first 28 days, particularly benefiting older adults, women, and individuals with hypertension.
While magnesium supplementation showed promise in reducing mortality and also improved longer-term outcomes, we noted that it was linked to longer stays in both ICU and hospital settings. Interestingly, we found that blood urea nitrogen levels may play a role in mediating the relationship between magnesium intake and mortality, suggesting a more complex interaction at play.
This research highlights the potential of magnesium as a valuable treatment for those grappling with HFpEF, especially certain at-risk groups. As we consider these findings, further research is needed to explore magnesium's effects more thoroughly and understand its full implications for patient care.
