26 Oct 2018 --- Researchers from Imperial College London have analyzed genetic data from over 48,000 people and revealed that higher iron levels are associated with an elevated risk of a certain type of stroke, called a cardioembolic stroke. These strokes are typically caused by blood clots traveling from the heart to the brain, and blocking blood and oxygen supply. They are often associated with a type of heart condition called atrial fibrillation, which causes an irregular heartbeat and affects around one million people in the UK.
