Diagnosis value of minimum exercise test of lactic acid and pyruvic acid for mitochondrial myopathy / 临床神经病学杂志

ABSTRACT

17.The abnormal results of METLP were found in 6(100%) patients with other myopathy.Most of them showed a high concentration of lactic acid post-aerobic exercise(L2),and sustainable to after rest,or even more higher(L3).3(21.4%)patients without myopathy showed abnormal results of METLP.Conclusions In all the indexes of METLP,the value of L2/P1 is the reliable index for diagnosis mitochondrial myopathy or no-myopathy;the value of L3/L2 is the most important index in differential diagnosis of mitochondrial myopathy and other myopathy.METLP plays a certain role in the diagnosis of the mitochondrial myopathy,but the clinical and pathological data ought to be combined.
