GPs advised post-MI stroke risk lasts three months

New research suggests the currently accepted one month of risk is inaccurate

A patient's risk for ischemic stroke after an MI remains elevated longer than the currently accepted one-month window, according to new findings.

The US study shows that the risk can last for up to three months, says researcher Dr Alexander Merkler, a neurologist at Weill Cornell Medicine in New York City.

"Now we can say that your stroke may be due to an MI that occurred in the last three months," he said.

"That's a big change, because it tells us that clinicians can better guide their patients in terms of why they had a stroke, and it can also lead to changes in stroke classification schemes and perhaps clinical trial selection criteria."

"From a primary-care perspective, patients who have had an MI want to know who is at risk for stroke and which subgroups are at risk for stroke. I think these results increase the awareness that having an MI is a big risk
