High salt intake is associated with a doubled risk of heart failure, according to a 12-year study in more than 4,000 people presented today at ESC Congress.
“High salt (sodium chloride) intake is one of the major causes of high blood pressure and an independent risk factor for coronary heart disease (CHD) and stroke,” said Prof Pekka Jousilahti, research professor at the National Institute for Health and Welfare, Helsinki, Finland. “In addition to CHD and stroke, heart failure is one of the major cardiovascular diseases in Europe and globally but the role of high salt intake in its development is unknown.”
This study assessed the relationship of salt intake and the development of heart failure. Estimation of individual salt intake is methodologically demanding and therefore suitable population-based cohorts are rare. This study used 24 hour sodium extraction, which is considered the gold standard for salt intake estimation at individual level.
This was a prospective follow-up study of 4 630 randomly selected men and women aged 25 to 64 years at baseline who participated in the North Karelia Salt Study and the National FINRISK Study between 1979 and 2002 in Finland. Baseline data collection included a self-administered questionnaire on health behaviour, measurements of weight, height and blood pressure, a venous blood sample for laboratory analysis, and collection of a 24 hour urine sample.
