Cardiac Ca(2+) regulation and the tuna fish sandwich.

Abstract

Following myocardial ischemia and reperfusion, there is a risk of fatal arrhythmias that result from damage to cellular Ca(2+) homeostasis mechanisms. n-3 Polyunsaturated fatty acids seem to protect against these arrhythmias by mechanisms involving the sarcoplasmic reticulum and the sarcolemma.
