Researchers solve puzzle of proteins linked to heart failure

Sudden cardiac death is a risk for patients with heart failure because the calcium inside their heart cells is not properly controlled and this can lead to an irregular heartbeat. New findings reveal mechanisms that underlie this life-threatening risk, provide new possibilities for fighting it.



Cellular aging increases risk of heart attack and early death

Every cell in the body has chromosomes with so-called telomeres, which are shortened over time and also through lifestyle choices such as smoking and obesity. Researchers have long speculated that the shortening of telomeres increases the risk of heart attack and early death.



An SOS from a damaged heart

Researchers find EKG anomalies that warn whose heart attacks could be fatal



Completion of proof of concept study for heart attack

Animal study demonstrates midkine treatment reduces heart muscle death by 27 per cent following heart attack



Study aims to cut heart attack risk

Scientists seeking volunteers for a study they hope could lead to the development of ‘functional foods’ to help cut the risk of cardiovascular diseases



Mediterranean-style diet improves heart function

A study of twins shows that even with genes that put them at higher risk of cardiovascular disease, eating a Mediterranean-style diet can improve heart function, according to research.



Overtime work is bad for the heart

Researchers found that people who worked three or more hours longer than a normal had a 60 per cent higher risk of heart-related problems such as death due to heart disease, non-fatal heart attacks and angina.



Detailed insight into failing heart cells

Researchers have been able to see how heart failure affects the surface of an individual heart muscle cell in minute detail, using a new nanoscale scanning technique developed at Imperial College London.



When the heart gets out of step

Although atrial fibrillation is not acutely life-threatening, it does increase the risk of developing more serious illnesses, such as cardiac insufficiency, stroke and dementia.



Cholesterol's link to heart disease gets clearer

By considering molecular-level events on a broader scale, researchers now have a clearer, if more complicated, picture of how one class of immune cells goes wrong when loaded with cholesterol.



Treating heart disease with your own cells

The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in less pain and an improved ability to walk.



Alzheimer's disease and chronic heart failure

Researchers report evidence from studies in animals and humans supporting a link between Alzheimer's disease and chronic heart failure.



Oxygen-saturated blood reduces damaged heart tissue

A recently published study demonstrates that an infusion of blood that is "supersaturated" with oxygen can reduce the amount of damaged heart muscle immediately following a life-threatening heart attack.



Insomnia is bad for the heart

A new study has found that people who suffer from insomnia have heightened nighttime blood pressure, which can lead to cardiac problems.



Fish oil's heart health benefits

There is mounting evidence that omega-3 fatty acids from fish or fish oil supplements not only help prevent cardiovascular diseases in healthy individuals, but also reduce the incidence of cardiac events and mortality in patients with existing heart disease.



Smokeless tobacco increases risk of heart attack and stroke

People who use smokeless tobacco products like snus have a slightly higher risk of having a fatal heart attack or stroke, according to research.



High calcium level and heart attack risks

Researchers may be able to predict future severe cardiac events in patients with known, stable coronary artery disease using coronary calcium scoring, according to a study.



Biotechnology: Molecule that regulates heart size

Using zebrafish, researchers have identified and described an enzyme inhibitor that allows them to increase the number of cardiac progenitor cells and therefore influence the size of the developing heart.



Folic acid to prevent congenital heart defects

Research into the prevention of neural tube defects shows that folic acid also decreases the incidence of congenital heart defects by more than 6%.



Heart Protection in Adulthood

A new study that delivered embryonic stem cells to mouse embryos in the earliest stages of development found that the resulting mice demonstrated a capacity to recover from cardiac injury in adulthood.
