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.

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.
