Excessive intake of salt can alter your heartbeat

Scientists at the University of Oulu, Finale, have conducted new studies that have found that a high salt diet increases the risk of atrial fibrillation, the most common form of cardiac arrhythmia.

People with atrial fibrillation are at a higher risk of stroke and, in extreme cases, can cause heart failure.

It's not new that excessive salt consumption increases the risk of cardiovascular disease, especially high blood pressure, myocardial infarction and stroke.

For this work, published in Annals of Medicine, the researchers followed a group of 716 middle-aged men and women for an average of 19 years to test their hypotheses. The team identified 74 people diagnosed with pre-existing atrial fibrillation and compared rates of disease incidence based on daily salt intake estimates for individuals.

As a result, they observed a higher incidence of disease in those who consume the highest levels of salt than those with the lowest intake.

"This study provides the first evidence that dietary salt may increase the risk of new atrial fibrillation, which adds to the growing list of the dangers of excessive salt intake in our cardiovascular health," says studio lead author Tero Pääkkö.

He added that "people who are at increased risk of atrial fibrillation may benefit from the limitation of salt in their diet."

More research

In any case, the researcher admits that "more confirmatory studies are needed" and that "the findings are preliminary."

He explained that only people in need of emergency care have been identified as atrial fibrillation, which can be underestimated.

He also stressed that they are based on an assessment of salt intake from the information gathered in a six-day food diary at the start of the study that can not be 100% reliable and suggests that people's eating habits change during the subsequent period.

Other factors

Salt intake is also independent of the risk of developing the disease after considering several risk factors such as age, body mass index, blood pressure, and smoking habit.

For example, researchers also note that the probability of suffering from atrial fibrillation increases with age and affects seven out of 100 people over 65 years of age.

"Considering that estimates suggest that more than three-quarters of salt already consumed in processed foods, reducing salt intake may have an extremely beneficial effect on newly born male fibrillations and cardiovascular diseases. , "said Pääkkö.
