When 27‑year‑old Boston engineer and avid runner Patrick Mascoli set out for a 10‑mile jog in July 2024, he never expected a medical emergency. While changing in a gym locker room, he felt an intense, burning pain on the right side of his head and a sudden loss of coordination.
Symptoms and Emergency Response
Mascoli described the sensation as “like a bomb went off” in his head. His vision blurred, his right leg moved involuntarily, and he struggled to stand. He managed to text his sister before collapsing again. First responders initially suspected dehydration and treated him for vertigo, but his condition did not improve.
Diagnosis: Stroke and a Hidden Heart Defect
At Boston Medical Center, a CT scan and MRI confirmed a stroke. Further testing, including a heart ultrasound with contrast bubbles, revealed a patent foramen ovale (PFO) – an opening between the heart’s upper chambers that normally seals after birth. Dr. Dheeraj Khurana, chief of cardiology at Episcopal Health Services, explained that in rare cases a clot can pass through a PFO and travel to the brain, causing a stroke.
Treatment and Recovery
Mascoli underwent a catheter procedure using an Abbott mesh device to close the PFO. He spent several days in the hospital, then began physical therapy with a walker. Although his mobility has improved, he still experiences fine‑motor challenges and anxiety about returning to long‑distance running.
Personal Reflections and Advice
Mascoli admits the event was “jarring and terrifying,” especially since he had no traditional risk factors. He urges others to recognize stroke symptoms—sudden headache, vision changes, weakness, vomiting, or speech difficulties—and call 911 immediately, regardless of age or fitness level. Cardiologists also recommend staying hydrated after strenuous exercise, avoiding tobacco, and monitoring blood pressure.
In October 2026, Mascoli completed the Chicago Marathon as part of Team Abbott, demonstrating that recovery is possible with perseverance and proper medical care.
