A common heart feature long thought to have negligible effects on human health and performance may be problematic at high altitude. That's a key finding from a study that looked at the effects of a ...

A common heart feature long thought to have negligible effects on human health and performance may be problematic at high altitude, according to University of Oregon researchers. That's a key finding ...

EUGENE, Ore., June 30 (UPI) --A small opening between the chambers of the heart, which usually closes during infancy but is thought to have only minor health effects in adults who have it, may cause ...

A patent foramen ovale (PFO) is a hole in the heart that doesn’t close as expected after birth. Before a baby is born, they have a hole between the left and right sides of their heart. This hole, ...

Patent foramen ovale (PFO) closure reduced the risk for recurrent ischemic stroke in most young and middle-aged adults with cryptogenic stroke but increased the risk for atrial fibrillation (AF) in a ...

Patent foramen ovale (PFO) may be associated with migraine, especially migraine with aura (MA), when the PFO is permanent right-left shunt (RLS), large RLS, and large-size PFO, a recent study found.

The efficacy of closure of a patent foramen ovale (PFO) in the prevention of recurrent stroke after cryptogenic stroke is uncertain. We investigated the effect of PFO closure combined with ...

Patent foramen ovale (PFO) has been linked to ischemic strokes of undetermined cause (cryptogenic strokes). PFO—a remnant of fetal circulation when the foramen ovale does not seal after birth—can ...

Whether closure of a patent foramen ovale reduces the risk of recurrence of ischemic stroke in patients who have had a cryptogenic ischemic stroke is unknown. In a multicenter, randomized, open-label ...

EUGENE, Ore. -- (June 30, 2015) -- A common heart feature long thought to have negligible effects on human health and performance may be problematic at high altitude, according to University of Oregon ...

Patent foramen ovale (PFO) is the most common congenital heart abnormality of fetal origin and is present in approximately ∼25% of the worldwide adult population. PFO is the consequence of failed ...

A foramen ovale is a hole in the heart. The small hole naturally exists in babies who are still in the womb for fetal circulation. It should close soon after birth. If it doesn’t close, the condition ...
