Urinary catechol excretion suggests sympathetic nervous system involvement in the mechanism of essential hypertension in patients without renal involvement.
No takes yet. Share an insight, caveat, or question.
Urinary catechols may reflect sympathetic activity in non-renal hypertension; cross-sectional data leaves open causal and clinical implications.
Teishi Ikoma (1965) studied this question.
