Mild, even symptomless impaired heart function can increase the chances of suffering a stroke, new research has indicated.
According to a study led by Dr Marco R Di Tullio of Columbia University and published in Stroke: Journal of the American Heart Association, suffering from left ventricular dysfunction (LVD) is five times more common in stroke patients than stroke-fee participants of the same age.
Heart failure has long been regarded as causing a greater risk of stroke, yet it now appears that even mild impaired function should be considered as increasing the possibility of suffering from stroke.
LVD was found to increase the risk of stroke by over three times in men and by nearly five times in women, a link which was noted in patients of all ethic backgrounds.
An important discovery was that the results seemed to contradict the theory that the level of heart dysfunction runs in parallel with the level of increased risk of stroke.
