This is a very interesting study. One wonders whether if this increased level of myocardial necrosis associated with diminished renal function applies to global cardiac ischaemia that occurs in cardiac surgery. It is well known that any degree of renal dysfunction is associated with poorer outcomes after cardiac surgery. This phenomenon may explain why.
What is not known and what surely must be a good avenue for study is why does impaired renal function lead to increased myocardial necrosis?
