Serum sodium levels starting at 143 mEq/L correlated with a 102% increased risk for left ventricular hypertrophy and a 54% increased risk for heart failure.īased on these data, the authors conclude serum sodium levels above 142 mEq/L in middle age are associated with increased risks for developing left ventricular hypertrophy and heart failure later in life.Ī randomized, controlled trial will be necessary to confirm these preliminary findings, the researchers said. In a cohort of about 5,000 adults ages 70-90, those with serum sodium levels of 142.5-143 mEq/L at middle age were 62% more likely to develop left ventricular hypertrophy. And for every 1 mEq/L increase in serum sodium within the normal range of 135-146 mEq/L, the likelihood of a participant developing heart failure increased by 5%. It also helped identify older adults with an increased risk for developing both heart failure and left ventricular hypertrophy, an enlargement and thickening of the heart.įor example, adults with serum sodium levels starting at 143 milliequivalents per liter (mEq/L) – a normal range is 135-146 mEq/L – in midlife had a 39% associated increased risk for developing heart failure compared to adults with lower levels. Looking at levels of serum sodium, which increases as the body’s fluid levels decrease, was especially useful in helping to identify participants with an increased risk for developing heart failure. To assess potential links with hydration, the team assessed the hydration status of the participants using several clinical measures. Approximately 11,814 adults were included in the final analysis, and, of those, the researchers found 1,366 (11.56%) later developed heart failure. In selecting participants for their retrospective review, the scientists focused on those whose hydration levels were within a normal range and who did not have diabetes, obesity, or heart failure at the start of the study. To start, they analyzed data from more than 15,000 adults, ages 45-66, who enrolled in the Atherosclerosis Risk in Communities (ARIC) study between 1987-1989 and shared information from medical visits over a 25-year period. “Similar to reducing salt intake, drinking enough water and staying hydrated are ways to support our hearts and may help reduce long-term risks for heart disease,” said Natalia Dmitrieva, Ph.D., the lead study author and a researcher in the Laboratory of Cardiovascular Regenerative Medicine at the National Heart, Lung, and Blood Institute (NHLBI), part of NIH.Īfter conducting preclinical research that suggested connections between dehydration and cardiac fibrosis, a hardening of the heart muscles, Dmitrieva and researchers looked for similar associations in large-scale population studies. It is also more common among adults ages 65 and older. Heart failure, a chronic condition that develops when the heart does not pump enough blood for the body’s needs, affects more than 6.2 million Americans, a little more than 2% of the population. ![]() Their findings, which appear in the European Heart Journal, suggest that consuming sufficient amounts of fluids throughout life not only supports essential body functioning but may also reduce the risk of severe heart problems in the future. Staying well-hydrated may be associated with a reduced risk for developing heart failure, according to researchers at the National Institutes of Health. Serum sodium levels may help identify adults with a greater chance of experiencing heart disease ![]()
