Talk to Vascular Surgeon on Bulging Veins

He suffered a heart attack on the 9th of April 2025 and had a stent placed. Following the procedure, he experienced low blood pressure and a headache, for which he was admitted to the ICU. I believe he received treatment overnight to help raise his blood pressure, among other supportive measures.

He initially stabilized, but then a day after collapsed while still in the hospital. CPR was performed, and he was placed on a ventilator for about a day and a half. He also received a blood transfusion due to low hemoglobin levels. He was discharged and is now back at home.

Now a days, he is mostly fine but today a very prominent bulging vein appered on his left forearm and he say it hurts a little. Is this a cause for concern?
