Can peritonael dialysis cause infection at abdomen then sudden death as acute coronary syndrome?

Yes/no: Pertioneal dialysis can definitely lead to abdominal infection, which can become life-threatening. However, this would not be expected to directly cause sudden death due to acute coronary syndrome. That said, many patients on dialysis are at increased risk for coronary disease due to some common risk factors for heart and kidney disease (diabetes and high blood pressure for example).

Multiple risks: Many dialysis patients are diabetic, hypertensive, anemic, frail and an added infection can impact badly. The dialysis catheter sites can be infected and lead to sepsis systemically with fever, low blood pressure etc. Many of these folks do have atherosclerosis and unidentified coronary disease that can act up!
