Heart disease is the leading cause of death worldwide and there are an estimated 460 deaths from heart attacks every day in the UK, according the British Heart Foundation. The inner lining of blood vessels should be smooth and unobstructed, but fatty deposits can begin to line the arteries and cause them to fur up,

When most people think about salt, the first image that comes to mind is of the tiny white grains that we might sprinkle on our food to liven up an otherwise bland dish. Many people forget that salt is also an essential mineral for most living things, responsible for regulating the levels of fluid in

Medical News Today, a health information website in the US, has a page dedicated to the cardiovascular system which provides helpful 3D models of the vascular tree and heart. To learn more about the cardiovascular system, including the anatomy of the heart, the heart’s electrical system, what the valves do, and to interact with a

Two drug classes known as SGLT2 inhibitors and GLP-1 receptor agonists, developed for use in patients with type 2 diabetes to lower blood glucose levels, have been shown in trials to have unexpected positive outcomes on the cardiovascular system. After 12 months of treatment with an SGLT2 inhibitor such as canagliflozin, dapagliflozin or empagliflozin, patients

Almost two thirds of heart attacks occur in people who do not have significant narrowings identified on a CT coronary angiogram. The process behind build-up of atheroma in the arteries is in part driven by inflammation within the vessels, and inflammation also provokes rupture of plaques within the arteries, which causes heart attacks. A new

After a bad day – or indeed even a good one! – it is very easy to sit down in front of the television with a bag of sweets and suddenly find the packet empty.

What we have not heard so much about is what happens after hospital, when patients are discharged home and how some of

Membrane-bound angiotensin-converting enzyme 2 (ACE2) is the functional receptor for SARS-CoV-2, the virus which causes COVID-19. Drugs such as angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) upregulate ACE2, raising concerns about their safety in patients with COVID-19. The BRACE-CORONA trial is the first randomised trial to address the question of whether patients

Who doesn’t love a shiny new smartphone? They wake us up in the morning, keep us connected to colleagues during the workday and friends and family at weekends, help us get from A to B, and indeed almost live our lives for us. These days there seems to be an app for everything and nothing
