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.

Zinc and ANP support heart health
ANP Increases Zn Accumulation During Reperfusion in Ex Vivo and In Vivo Hearts.
We explored the relationship between atrial natriuretic peptide (ANP) and zinc, particularly how they work together to protect the heart during reperfusion after ischemia. The study involved comparing various experimental rats and mice, as well as assessing plasma samples from patients experiencing heart-related conditions.
Our findings highlighted that ANP significantly boosts zinc levels during the crucial period of reperfusion. This increase in zinc appears to protect heart cells from damage by helping to maintain mitochondrial health, effectively reducing the size of heart tissue injuries. We observed that when ANP was administered alone, it improved heart function, but combining it with a substance that removes zinc led to poorer outcomes.
We also noted that ANP works through a specific signaling pathway (the PI3K pathway) to decrease levels of a zinc transporter, ZnT8, which is upregulated during reperfusion injury. Interestingly, both ANP and zinc had a role in regulating important proteins linked to heart health. Overall, our research suggests that managing zinc levels through ANP treatment can help shield the heart from the harsh effects of ischemia/reperfusion injury.

Zinc effects on sleep in CVD
Role of toxic and essential elements in sleep duration of patients with cardiovascular diseases.
We investigated how zinc levels may influence sleep duration in patients with cardiovascular diseases (CVDs). Our study included 150 participants from the Ravansar Non-Communicable Disease Cohort Study, where we measured serum concentrations of zinc and other elements, including essential minerals and toxic metals.
A significant finding was that we observed a strong correlation between higher zinc concentrations and optimal sleep duration. Specifically, the data indicated that as zinc levels increased, the likelihood of achieving an appropriate sleep duration of 7 to 8 hours also increased.
However, when we looked deeper into the data, we did not find significant differences in the serum concentrations of both essential and toxic elements across different sleep duration categories. This suggests that while zinc may play a role in regulating sleep duration, it does not entirely account for sleep issues among CVD patients.
Ultimately, our results encourage further exploration of zinc's impact, particularly as it relates to sleep quality and overall health in individuals with cardiovascular conditions.

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.
Zinc is a versatile metal known for its various applications in industry and health. It is a bluish-white metallic element represented by the symbol Zn and atomic number 30 on the periodic table. Zinc is primarily used for galvanizing steel to prevent rusting, in the manufacturing of alloys, and as a component in batteries. Additionally, zinc plays a crucial role in biological processes, making it an essential trace element in the human diet. It is involved in immune function, protein synthesis, wound healing, and DNA synthesis, highlighting its importance in maintaining overall health and well-being.
While zinc is an essential mineral that plays a crucial role in various bodily functions, its direct influence on cardiovascular disease is still under investigation. Zinc is involved in maintaining proper immune function, antioxidant activity, and inflammation reduction, all of which are important for heart health. Some studies suggest that adequate zinc levels may be related to improved cardiovascular outcomes due to its role in reducing oxidative stress and inflammation, factors often associated with heart disease. However, the evidence is not conclusive enough to confidently assert that zinc supplementation can prevent or treat cardiovascular disease.
Incorporating zinc-rich foods such as meat, shellfish, legumes, seeds, nuts, dairy products, and whole grains into your diet can help maintain adequate levels of this mineral, which may support overall heart health. Before considering zinc supplements for cardiovascular benefits, it’s advisable to consult with a healthcare professional to determine individual needs and any potential risks. Overall, while zinc is important for health, it should not be viewed as a standalone solution for cardiovascular disease but rather as part of a balanced diet and healthy lifestyle.
Recent research sheds light on the potential benefits of zinc supplementation in relation to cardiovascular disease, although the findings are nuanced. For example, a study involving diabetes patients indicated that adequate dietary zinc intake might positively influence cardiovascular health and reduce the risk of atherosclerotic cardiovascular disease (ASCVD) [1]. Additionally, zinc has been shown to play a protective role in heart cell injury, particularly during episodes of ischemia and reperfusion, suggesting a direct link to heart function improvement [6].
Moreover, zinc deficiency has been associated with increased cardiovascular risk factors among obese individuals [4] and may contribute to inflammation and cardiac remodeling [5]. While these studies emphasize the importance of zinc in cardiovascular health, they also point out the need for further comprehensive research to determine how zinc supplementation can be effectively used to enhance heart health. Thus, while there's growing evidence supporting the role of zinc in cardiovascular protection, particularly under specific health conditions, more extensive clinical trials are necessary to clearly establish its benefits and applications in wider populations.

Zinc's role in cardiovascular health
A pilot study on the relationship between zinc deficiency and anthropometric and metabolic parameters in obese adults in Serbia.
We explored how zinc deficiency relates to cardiovascular disease among obese adults in Serbia. By conducting a case-control study with 31 obese participants and 31 control subjects, we set out to understand how zinc affects body weight, lipid levels, and inflammation.
Our findings revealed that obese individuals had significantly lower serum zinc levels compared to those who weren't obese. We observed notable negative correlations between zinc levels and various health metrics, including body weight, body fat percentage, and triglycerides.
On the flip side, higher zinc levels correlated positively with beneficial high-density lipoproteins. Interestingly, we noted that the atherosclerotic index was significantly linked to zinc, suggesting that zinc status could play a role in assessing cardiovascular risk in obese individuals.
While this study spotlights zinc's intriguing relationship with cardiovascular risk factors, it does not specifically evaluate the benefits of zinc treatment on cardiovascular outcomes.

Zinc's role in heart health
Exacerbation by knocking-out metallothionein gene of obesity-induced cardiac remodeling is associated with the activation of CARD9 signaling.
In our exploration of the effects of zinc on cardiovascular health, we examined how the metallothionein (MT) gene influences heart remodeling linked to obesity. Using a mouse model fed a high-fat diet (HFD), we observed that the deletion of the MT gene intensified obesity and its related cardiac issues, such as inflammation and hypertrophy.
Highlighting the role of zinc, we found that it can help counteract these negative changes. Zinc supplementation led to an increase in MT levels, which appeared to protect against the exaggerated effects of HFD. When we looked closer, mice without the MT gene showed heightened activation of the CARD9 and BCL10 proteins, which are associated with inflammation and cardiac remodeling.
This study indicates that zinc not only supports the regulation of trace metals in the body but may also play a crucial protective role against the cardiac damage caused by obesity. In fact, it seems that zinc could be an essential ally in managing cardiovascular risks linked to high-fat diets and obesity-related inflammation.
