[Motor nerve conduction velocity in arterial hypertension]

Motor nerve conduction velocity was studied in a group of 44 hypertensive patients; velocity was measured at the level of the median and external popliteal sciatic nerves. From the series were excluded those hypertensive subjects with renal insufficiency, diabetes mellitus and peripheral arterial disease. No significant differences were observed in MNCV values compared to controls. Within the hypertense group, no appreciable variations were observed depending on the duration and degree of hypertension, and signs of visceral damage (assessed at myocardial and retinic levels). The results do not confirm previous published data suggesting the existence of MNCV reduction during arterial hypertension, the reduction being considered an subclinical expression of peripheral neuropathy and an index of the gravity of visceral damage during hypertensive disease.
