Don't let yourself dry out!
Dehydration increases the risk of heart failure by 39%
Svetlana Maslova, Hi-tech+
This conclusion was reached by scientists after tracking various laboratory parameters in healthy people for 25 years. In addition to heart failure, low hydration increased the risks of hypertrophy of the left ventricle of the heart, and also increased the volume of the heart. Now scientists call the drinking regime a new daily prevention of cardiovascular diseases, along with limiting salt intake.
The consumption of a sufficient amount of fluid is necessary to maintain all vital functions of the body, including the efficient functioning of the heart and optimal function of blood vessels. According to various sources, women should consume at least 1.5-2 liters of liquid per day, and men — 2-3 liters.
(Just don't forget that most of this amount is contained in cooked foods. And for a detailed analysis of the tale about 8 glasses of water, see here – VM).
Most people don't follow these guidelines on a regular basis. It was for such people that scientists from the USA began to observe.
Article Dmitrieva et al. Middle age serum sodium levels in the upper part of normal range and risk of heart failure is published in the European Heart Journal – VM.
In the study Almost 12 thousand volunteers from 45 to 66 years old participated in the National Institutes of Health of the USA, who for 25 years provided various information about their health, including blood tests. The initial sample included initially healthy people with normal indicators of hydration, without diabetes, obesity and heart failure. During the experiment period, 12% of them were diagnosed with heart failure.
The assessment of the relationship between the level of hydration and the risks of the disease was carried out according to various laboratory blood parameters, the level of sodium in serum. Indicators in the range of 135-146 mmol/l are considered normal. Scientists noted that volunteers with indicators from 143 mmol/l had a 39% higher risk of developing heart failure. For each additional item, the risks increased by another 5%.
Then the scientists found that in elderly people after 70 years, indicators above 143 mmol/l correlated with an increase in the risk of left ventricular hypertrophy by 102%, and heart failure by 54%.
Serum sodium levels and fluid intake can be easily assessed during clinical examinations. Simple tests allow doctors to identify patients at risk of cardiovascular diseases who will need to be informed about ways to prevent dehydration.
"Like reducing salt intake, sufficient fluid throughout the day to maintain water balance are ways to help the heart and reduce the long—term risks of heart disease," concluded the author of the work Natalia Dmitrieva.
