Heart rhythm disturbance may explain many strokes | CTV News

At the International Stroke Conference 2013 in Hawaii, lead investigator Dr. David Gladstone presented new research findings that might explain the causes of stroke in individuals with no pre-determined risk factors (1).

Irregular heart rhythm (or atrial fibrillation) is known to be a risk factor of strokes, but detection through heart monitoring can lead to treatment and stroke intervention (1). However, heart monitoring normally occurs over a period of one to two days and irregular heart rhythm may occur outside this window of monitoring.

Dr. Gladstone and his team of researchers have just completed a three year clinical trial, involving 572 patients that wore a non-intrusive 30-day heart monitor. This study allowed the research team to monitor patients that tested negative for atrial fibrillation in regular monitoring and found that one in six individuals with unexplained transient ischemic attack or stroke, could be attributed to atrial fibrillation (2).

Dr. Gladstone, UTSP doctor, University of Toronto associate professor and director of the Regional Stroke Prevention Clinic of Sunnybrook Health Sciences Centre speaks on the study:

“The hope is that earlier detection and treatment of atrial fibrillation may lead to more strokes prevented and more lives saved,” said Dr. Gladstone (2).
