Water is Key to Our Heart’s Good Health

We all know, or should know, that drinking lots of pure water daily can improve our health in many ways, but here’s a lesser-known benefit…“– Paul Ebeling

New research suggests that middle-aged adults can lower their long-term risk for heart failure by simply drinking enough water on a daily basis.

The finding follows an analysis that stacked heart health up against blood salt levels, an indicator for overall fluid intake among nearly 16,000 middle-aged men and women over a 25-yr period.

“The importance of hydration has been on the cardiovascular radar for a long time,” noted study author Natalia Dmitrieva, a senior researcher with the US National Heart, Lung, and Blood Institute.

Ms. Dmitrieva said it has to do with the way the lack of liquid intake can affect an individual’s sodium balance, hormone levels and kidney function in ways that may ultimately undermine proper heart function.

Specifically, she cited problems that can begin when a lack of fluid intake ends up driving a person’s blood salt levels above a specific threshold namely, 142 millimoles per liter [mmol/L].

For their study, Ms. Dmitrieva and her colleagues used that threshold as a reliable indicator of an individual’s overall hydration status, even though by current standards that level would typically be deemed to be within the “normal range” for blood sodium.

But the study team settled on that trigger point because when salt levels exceed that, a “hormone is secreted from the brain. This hormone acts on the kidney to activate water preservation mechanisms,” she said.

The result: urine excretion drops, setting in motion a spike in high blood pressure risk.

And elevated blood pressure is not the only cardiovascular threat posed by dehydration. Because over time, insufficient fluid intake can also directly undermine the cellular integrity of the heart muscle itself.

The study suggests that maintaining good hydration can prevent or at least slow down the changes within the heart that lead to heart failure.

All the study participants were between 44 and 66 anni when they were 1st enrolled in the study.

Each participant’s salt levels were evaluated 5Xs over the following 25 yrs, as participants aged up to between 70 and 90 yrs.

Participants were then grouped into 5 different blood sodium level categories, according to their results, ranging from a low of between 135 to 139.5 mmol/L to a high of between 144 to 146 mmol/L.

The study team then tracked heart failure incidence, along with problems with the heart’s left ventricular pumping capacity over the ensuing yrs.

The result: those whose blood sodium levels had exceeded 142 mmol/L in middle age saw their risk for both heart issues surge when they hit age 70 and older.

Going forward the hydration threshold identified by her team could “potentially be used by physicians during regular physical exams to identify patients who should be evaluated for their drinking habits, and to make recommendations to increase the intake of fluids if this evaluation finds that the patient’s liquid consumption is low.”

The Big Q: How much liquid should middle-aged men and women ideally drink on a daily basis to protect their hearts?

The Big A: “Recommendations vary in different countries,” Ms. Dmitrieva stressed, with the Institute of Medicine in the United States recommending a liquid intake at just under 3.2 quarts for men, and just over 2 quarts for women.

The findings are only hypothesis-generating to address whether more fluid intake would reduce the risk for left-ventricle health and heart failure and that “too much fluid in the wrong patient could be harmful.”

Mr. Dmitrieva and her colleagues were scheduled to present their findings at the virtual annual meeting of the European Society of Cardiology, 27-30 August, Research presented at medical meetings should be viewed as preliminary until published in a peer-reviewed journal.
