Staying Well-Hydrated Could Cut Heart Failure Risk

Staying well-hydrated could cut heart failure risk, according to new research. It suggests that drinking sufficient water throughout life could prevent the risk of developing heart failure.

Health specialists generally suggest a daily fluid intake of 1.6 to 2.1 liters for women and 2 to 3 liters for men. However, several studies have shown that many people fail to meet even the lower ends of these ranges.

A serum sodium test measures the amount of sodium in your blood. Drinking less fluid can increase the concentration of serum sodium in your body, contributing to the development of heart failure.

In the new study, the researchers analyzed whether serum sodium concentration in middle age, as a measure of hydration habits, anticipates the development of heart failure 25 years later. The association between hydration and thickening of the walls of the heart's main pumping chamber was also investigated.

The research used the Atherosclerosis Risk in Communities (ARIC) study that involved 15,792 adults who were 44 to 66 years old at recruitment. These participants have evaluated over five visits until age 70 to 90.

The study findings revealed that maintaining good hydration can prevent the changes within the heart that lead to heart failure.

“The results suggest that good hydration throughout life may decrease the risk of developing left ventricular hypertrophy and heart failure. In addition, our finding that serum sodium exceeding 142mmol/l increases the risk of adverse effects in the heart may help to identify people who could benefit from an evaluation of their hydration level,” study author Dr. Natalia Dmitrieva said.
