Abstract:
BACKGROUND:Although the effects of salt intake reduction on casual blood pressure have been extensively studied in hypertensive individuals, data on reductions of added salt on arterial stiffness in both normotensive and prehypertensive subjects are scarce. OBJECTIVE:To evaluate the effects of progressive reduction in added salt intake (from 6 grams to 4 grams per day) on peripheral and central blood pressure and arterial stiffness in normotensive, prehypertensive and hypertensive individuals. METHODS:This was a single-blinded clinical trial with 13 weeks of follow-up. Normotensive (≤ 130/85 mmHg), prehypertensive (≥ 130 e < 139/≥ 85 e < 90 mmHg) and stage 1 hypertensive individuals (< 139/≥ 85 and < 90 mmHg) were assessed. Casual blood pressure measurements and ambulatory blood pressure monitoring were performed using the automated OMRON 705CP device, and central blood pressure was measured using the Sphygmocor®. Twenty-four-hour urinary sodium excretion and the amounts of added salt consumed were measured. Statistically significance level was set at p < 0.05 for all analysis. RESULTS:A total of 55 participants (18 normotensive, 15 prehypertensive and 22 hypertensive), median age 48 years (IQR:39-54) were studied. The groups were not different in age or sex. No difference was observed in blood pressure or sodium excretion levels before and after the intervention. No significant changes in arterial stiffness parameters were observed. CONCLUSION:The progressive reduction in added salt intake during a period of 13 weeks did not cause significant reductions in peripheral and central blood pressure. (Arq Bras Cardiol. 2020; 114(3):554-561). FUNDAMENTO:Os efeitos da redução na ingestão do sal sobre a pressão arterial (PA) casual de hipertensos já foram amplamente estudados, entretanto essa análise ainda é escassa no contexto da redução exclusiva do sal de adição na rigidez arterial e em indivíduos normotensos e pré-hipertensos. OBJETIVO:Avaliar os efeitos da redução progressiva na ingestão do sal de adição (de 6 para 4 g/dia) sobre os valores da pressão periférica e central, a rigidez arterial em normotensos, pré-hipertensos e hipertensos. MÉTODOS:Ensaio clínico, simples cego com 13 semanas de seguimento. Foram avaliados normotensos (≤130/85 mmHg), pré-hipertensos (≥130 e <139/≥85 e <90 mmHg) e hipertensos estágio 1 (≥140 e <160/≥90 e <100 mmHg). Utilizou-se medida casual e monitorização residencial da PA com aparelho automático OMRON 705CP, medida central da PA com Sphygmocor®, dosagem do sódio urinário de 24h (colhido no intervalo entre cada visita) e mensuração de sal de adição. Foi adotado nível de significância p<0,05 para todas as análises. RESULTADOS:Foram avaliados 55 participantes (18 normotensos; 15 pré-hipertensos; 22 hipertensos) com mediana 48 anos (IQ:39-54). Os grupos foram semelhantes em relação a idade e sexo. Não houve diferença entre medidas de PA e excreção de sódio antes e depois da intervenção. Os parâmetros de rigidez arterial também não sofreram alterações significativas. CONCLUSÃO:A redução gradativa da ingestão de sal de adição num seguimento de 13 semanas não foi capaz de reduzir de maneira significativa os valores periféricos e centrais da PA.
