Green tea compound could hold the key to preventing thousands of deaths each year caused by strokes and heart disease, a new study, conducted by the British Heart Foundation, has claimed.
Researchers had been researching epigallocatechin-3-gallate (EGCG), a compound found in green tea, for its ability to reduce amyloid plaques in the brains of Alzheimer’s disease patients.
Researchers from Lancaster University and the University of Leeds discovered that EGCG compound found in green tea, currently being studied for its ability to reduce amyloid plaques in the brain in Alzheimer’s disease, also breaks up and dissolves potentially dangerous protein plaques found in blood vessels.
“The health benefits of green tea have been widely promoted and it has been known for some time that EGCG can alter the structures of amyloid plaques associated with Alzheimer’s disease. Our results show that this intriguing compound might also be effective against the types of plaques which can cause heart attacks and strokes,” says researcher David Middleton.
The study is published in the Journal of Biological Chemistry.
The team is now working on finding ways to introduce effective amounts of EGCG into the bloodstream without it being necessary to drink large and potentially harmful quantities of green tea.Follow @gorkhapost
Sudden cardiac arrests are more likely to happen on any day at any time : Study
A new study has showed that sudden cardiac arrests are more likely to happen on any day at any time, challenging previous claims that weekday mornings — especially Mondays — were the danger zones.
Previously heart experts have long believed that weekday mornings were the danger zones for unexpected deaths from sudden cardiac arrests.
“While there are likely several reasons to explain why more cardiac arrests happen outside of previously identified peak times, stress is likely a major factor,” said Sumeet Chugh, a Professor of medicine from the Smidt Heart Institute in the US.
“We now live in a fast-paced, ‘always on’ era that causes increased psycho-social stress and possibly an increase in the likelihood of sudden cardiac arrest,” Chugh added.
Almost 17 million cardiac deaths occur annually worldwide while the survival rate from sudden cardiac arrest is less than one per cent.
For the study, published in the journal Heart Rhythm, Chugh’s team analysed data on 1,535 from the community-based Oregon Sudden Unexpected Death Study between 2004 to 2014, among which only 13.9 per cent died in the early morning hours, the findings revealed.
All reported cases were based on emergency medical service reports containing detailed information regarding the cause of the cardiac arrest.
“Because sudden cardiac arrest is usually fatal, we have to prevent it before it strikes,” Chugh said. “Our next steps are to conclusively determine the underlying reasons behind this shift, then identify public health implications as a result,” he added.
Apart from stress, other contributing factors may be a shift in how high-risk patients are being treated, as well as inadequacies in how past studies have measured time of death caused by sudden cardiac arrest.Follow @gorkhapost
