Scientists from Heinrich-Heine-University and the IUF-Leibniz Research Institute for Environmental Medicine in Düsseldorf, Germany, suggest that consuming the amount of caffeine equivalent to four cups of coffee might be enough to protect the cells of the heart.
In the study, the scientists discovered a new enzyme within mitochondria appearing to be relevant to caffeine’s protecting effect: p27. Using the mice models, the researchers found that caffeine protected against heart damage in prediabetic, older, and obese mice.
Lead researchers Judith Haendeler concludes: “These results should lead to better strategies for protecting heart muscle from damage, including consideration of coffee consumption or caffeine as an additional dietary factor in the elderly population.”
According to a recent analysis of existing studies in the UK, single, divorced and widowed people have higher chances to develop heart disease and stroke. That’s why the authors of the study believe that being married can be another factor that cuts the risk of cardiovascular disease.
For the study, a team of researchers examined 34 studies from around the world which included over 2 million participants altogether aged from 42 to 77. The results of the analysis showed that single, divorced or widowed people had 42% higher risk of developing cardiovascular disease compared to married participants.
Lead study author Chun Wai Wong and colleagues conclude: “Future research should focus around whether marital status is a surrogate marker for other adverse health behavior or cardiovascular risk profiles that underlines our reported findings or whether marital status should be considered as a risk factor by itself.”
A large Swedish study suggests that eating a handful of nuts three times a week may reduce the risk of developing an irregular heartbeat, which is considered to be a major cause of stroke.
For the study, a team of researchers from Karolinska Institute looked at over 60,000 Swedish adults and tracked their consumption of nuts and almonds, as well as their heart health during about 17 years. Having analyzed the received data, the scientists concluded that eating nuts were associated with lower risk of heart attack and stroke.
The authors of the study concluded: “Since only a small proportion of this population had moderate (about 5%) or high (less than 2%) nut consumption, even a small increase in nut consumption may have large potential to lead to a reduction in incidence of atrial fibrillation and heart failure in this population.”
A new research from the University of Edinburgh, UK, suggests that cheap cilostazol tablets may reduce damage to arteries, which lead to blood clots, resulting in strokes and cognitive decline.
The researchers plan to assess the medications’ ability to cut the risk of lacunar strokes and dementia within the next three years.
Dr. Doug Brown from the Alzheimer’s Society says: “With no new dementia drug in 15 years – but one person every three minutes developing it – the race is on to find desperately needed drugs that can prevent people getting dementia. Finding an existing drug which can prevent dementia would be a huge breakthrough.”
According to a recent study, published in The Journal of Physiology, exercising four to five times per week may help stop the main arteries to the heart from stiffening up.
The researchers from the US have found that those who exercise four to five times per week had healthier large central arteries and healthier middle-sized ones.
Lead author of the study Dr. Benjamin Levine of the Institute for Exercise and Environmental Medicine in Dallas, USA, explains: “This work is really exciting because it enables us to develop exercise programs to keep the heart youthful and even turn back time on older hearts and blood vessels.”
