Pyrophosphate myocardial imaging

Seminars in Nuclear Medicine, 1980
Technetium-99m pyrophosphate myocardial scintigraphy is a sensitive indicator of acute myocardial infarction (AMI). Over 90% of acute myocardial infarctions will result in an abnormal scintigram. The sensitivity is highest for transmural myocardial infarction, reaching levels of 95% or better.

Metabolism of extracellular pyrophosphate

Current Opinion in Rheumatology, 2003
Accumulation of excess inorganic pyrophosphate in cartilage matrix leads to calcium pyrophosphate dihydrate crystal deposits. Recent animal and human studies now support a role for physiologic extracellular pyrophosphate levels in preventing ectopic apatite calcification in joints and extracellular tissues.

A Crystallographic Investigation of Phosphoantigen Binding to Isopentenyl Pyrophosphate/Dimethylallyl Pyrophosphate Isomerase

Journal of the American Chemical Society, 2004
We report the crystallographic structures of the potent phosphoantigens Phosphostim (the bromohydrin of isopentenyl pyrophosphate) and E-4-hydroxy-3-methyl-but-2-enyl pyrophosphate bound to the mevalonate pathway enzyme isopentenyl pyrophosphate/dimethylallyl pyrophosphate isomerase (IPPI).
