Perfusion-contraction match and mismatch.

The present article describes the concept of perfusion-contraction matching originally proposed by Ross, goes on to critically discuss the available techniques to measure both regional myocardial blood flow and function in the experimental and clinical setting, and finally analyzes the available evidence for perfusion-contraction match and mismatch during normoperfusion and various scenarios of myocardial ischemia/reperfusion, including acute and subacute ischemia, coronary microembolization, stunning and hibernation.
