title: [Major deficiency in serum lactate dehydrogenase 1 and 2 isoenzymes: a possible pathogenesis for angina pectoris with normal coronarography].
abstract: Sometimes angina pectoris with normal coronarography can be explained by several enzymatic disturbances. These are as follow: -- a marked decrease of serum lactate-deshydrogenase 1 and 2 isoenzymes, -- the absence of myocardial lactate-deshydrogenase isoenzymes, --the decreased affinity for substrate lactate of residual lactate-deshydrogenase in serum, -- the increased production of 2,3 diphosphoglycreate.
