This Salt Awareness Week, Dr Queenie Chan puts the salt intake guidelines to the test and looks at the reality of curbing salt intake for better heart health.
Salt and sodium are often used interchangeably, but they’re not exactly the same thing. Sodium is a mineral that occurs naturally in foods or is added during manufacturing or both. Table salt is a combination of sodium and chloride, which was one of the most valuable modes of currency in ancient times. It has been used to preserve food for thousands of years and it is most commonly associated as a form of food seasoning. Salt also plays a role in food processing, providing texture and enhancing colour. (more…)
Dr Michela Noseda took cardiac cells to the stage at her recent TEDx talk on how scientific approaches she uses can help us understand how to beat one of the biggest killers of our time – heart attacks.
Heart attack (myocardial infarction) remains the foremost killer worldwide. The prevalence remains high despite the fact that we have been reducing risk factors; stopping smoking, eating a healthy diet and exercising. In fact, the persistence of myocardial infarction as the most frequent cause of death is related to an ageing population and the move of people towards big cities. (more…)
Ahead of the 2018 FIFA World Cup kick off, Dr Peter Wright explores how the stress and excitement of watching football isn’t all fun and games for our cardiovascular health.
Since time immemorial, sport has functioned as a useful substitute for direct physical conflict between, tribes, towns and nations. This year all eyes turn towards Russia, where the 21st edition of the FIFA World Cup will take place. The Russian word ‘mira’ may translate as both ‘world’ and ‘peace’, but as the pre-eminent competition of humanity’s favourite sport, ‘Чемпионат мира по футболу 2018’ is likely to be anything but relaxing for the players, officials and millions of spectators worldwide.

With London’s biggest running event of the year upon us, sport-expert Tim Grove gives a low down on the benefits of running for a healthy heart.
Is physical activity good for us?
London Marathon – the biggest sporting spectacle of the year – is fast approaching. This Sunday will see over 40,000 runners take part in the gruelling 26.2-mile course starting at Blackheath and finishing in front of Buckingham Palace. The event is highly televised with elite runners, celebrities, politicians and fundraisers all taking part together. The London Marathon has gained popularity since its inception in 1981 and has raised over £450 million for charity, making it the world’s largest annual fundraising event. With its high media profile, the London Marathon certainly sparks the enthusiasm of the general public with many taking to streets in the bid to train for next year’s event or for shorter distance races.

In the post, PhD student Mona Allouba, calls for a better understanding of the genetics of Egyptians in a bid for personalised treatments for cardiomyopathy patients
Over the past decade, several institutions in Egypt have been making huge scientific progress that is steadily reaching worldwide recognition. It is under these circumstances that I have been fortunate to join the Magdi Yacoub Foundation (MYF), which is recognised as one of Egypt’s most prominent charity organisations. The Aswan Heart Centre – located along the banks of the Nile in Aswan – is an integral part of MYF, offering state-of-the-art medical services for the underprivileged. It focuses on expanding the research on heart disease across the Middle East and beyond to contribute to the world’s scientific knowledge. (more…)
Upasana Tayal was shortlisted for the MRC Max Perutz Science Writing Competition 2017 for the following article on her research into a heartbreaking disease called dilated cardiomyopathy.
“Hearts will never be practical until they can be made unbreakable”, said the Wizard of Oz. “But I still want one”, replied the Tin Woodsman.
Your heart makes you human, makes you love, and keeps you alive. In just one year, it will beat 40 million times, without rest or time off for good behaviour. A pretty impressive piece of machinery you might agree, no wonder the Tin Man wanted one so much.
And like many things in life, he may have wished for a big heart at the end of the yellow brick road. (more…)
PhD student Liam Couch unravels the science behind breaking heart syndrome and explains how his research is helping to understand the unknowns of this condition.
Broken heart syndrome, officially known as takotsubo syndrome, is an acute type of heart failure, where the bottom of the heart stops beating in situations of extreme stress. A condition predominantly affecting post-menopausal women, it has been dubbed broken heart syndrome owing to the frequent occurrence during bereavement after the loss of a loved one. However, this is just one example of the various circumstances in which takotsubo syndrome can occur. Indeed, any stressful event can lead to a surge in adrenaline which can result in takotsubo syndrome. This could be physical or emotional, and includes trauma such as car accidents, drug abuse, and even happy events such as weddings! (more…)
On World Heart Day, Sian Harding Head of the BHF Centre of Regenerative Medicine looks at how the Centre’s cutting-edge science is working towards building new heart muscle.
We are excited by the news that our BHF Regenerative Medicine Centre has been renewed for another four-year term from 1 October 2017! At Imperial we have been concentrating on the big challenge of producing new muscle for the damaged heart, along with our partners in the Universities of Nottingham, Glasgow, Hamburg and Westminster.
The heart has a very limited capacity to repair itself after a heart attack, or during the more insidious damage from high blood pressure, diabetes or chemotherapy. We have been looking at various kinds of stem cells to explore their power to become new cardiac muscle cells – one of the big successes of the current Centre. Pluripotent stem cells – those which have the capability of turning into any cell type in the body – can now be turned very efficiently into beating heart muscle in the laboratory dish, and made into strips of engineered heart tissue. Our partner, Professor Chris Denning, at the University of Nottingham has automated the process of making the cells and Professor Thomas Eschenhagen in Hamburg has contributed his technology for converting this into muscle.

In the post, Neil Dufton asks: How can we bring together imaging technology, art and philosophy to shape scientific research?
When we think of vascular health we are often guilty of presuming that we are primarily discussing the heart. Clearly the heart has a major role to play in regulating your blood flow; once our blood has exited the heart it must supply nutrients to every organ of our body and back to the heart in a cycle that takes about one minute. Any hindrance from a cholesterol-blocked artery or blood clot can have catastrophic results – however by the time we reach retirement our circulation will have exceeded 30 million laps around the body! This incredible feat is made possible by our blood vessels that not only form a vast network during your development in the womb, but are also constantly growing and remodelling throughout our life time. Our Vascular Science research group at the National Heart and Lung Institute is particularly interested in endothelial cells – the cells that line every blood vessel in our body. We want to understand how they work together to grow and form new vessels (a process called angiogenesis), as well as how they maintain these structures in response to injury and disease. (more…)
From gluten-free to detox diets, Dr Anusha Seneviratne dissects the scientific evidence (or lack of) behind eccentric diets.
Magazines and newspapers are full of so-called ‘tips’ or ‘advice’ for the image conscious, detailing extreme diets followed by the rich and famous to achieve dramatic weight loss, or new diets apparently supported by the latest scientific research. One example is the gluten-free diet, made fashionable particularly in the sporting world by former world number one tennis player Novak Djokovic (1). Having had a reputation for being physically weaker than his rivals, Djokovic was eventually diagnosed with coeliac disease and the resulting gluten intolerance. Eliminating gluten from his diet transformed his career. (more…)
