[On the sodium to potassium ratio in daily urine of patients with arterial hypertension].

The aim of the study was to measure Na:K ratio in 24-hour urine depending on salt consumption. The subjects were 230 patients with arterial hypertension (AH). The study found a significantly higher salt consumption by AH patients, and decrease of K excretion together with increase of Na excretion. Measurement of Na:K ratio in these patients demonstrated that their salt consumption should be limited, and the proportion of food containing K should be increased.
