As global temperatures rise, scientists issue a warning about heart disease.

  • Climate change may lead to an increase in the frequency of heat waves that are harmful to human health.
  • Increased temperatures during a 2019 heatwave were shown to be strongly associated with weight loss, according to a countrywide study of 1,420 persons with chronic heart failure in France.
  • Because fluctuations in weight can lead to lung congestion, the primary reason for hospitalization, weight monitoring is crucial for this illness.

The heart’s ability to circulate blood throughout the body as effectively as it should is compromised in chronic heart failure.

As a result, symptoms including lung congestion, fluid accumulation, edema, fluid retention, weariness, dizziness, and irregular or quick heartbeats might occur.

People with heart failure are often administered diuretics, commonly referred to as water tablets, to assist them to produce more urine, which will help to lessen any swelling and shortness of breath. The amount of salt and water that the body excretes in urine is increased by these drugs.

Notably, in France, Europe endured a severe heatwave in the summer of 2019.

A heatwave will cause weight changes in those with cardiac issues, according to researchers at the University of Montpellier, and telemonitoring may be used to measure these changes.

Employing technology to keep an eye on people with heart failure

According to the most recent ECS recommendations, individuals with cardiac issues who have a change in their symptoms or a rapid, unexpected weight gain should take more diuretics or call their doctor, since these signs may point to a deterioration of their health.

Telemonitoring, which employs technology to track a person’s weight in real-time, is an efficient method of monitoring patients with heart failure.

Individuals must weigh themselves and enter data into an electronic system according to the telemonitoring protocol, frequently using a smartphone. However, if employees are not taught how to submit data accurately or if they forget to do so, this strategy might influence both compliance and data gathering.

Telemonitoring has the advantage of speedy data transfer to the clinic, where doctors and medical staff may be informed and notified to take appropriate action if necessary.

Investigating how people with heart failure are affected by severe heat

Using a system run by CDM e-Health, an electronic chronic illness management system, researchers gathered and examined data from persons with heart disease for the current study.

To evaluate the consequences of two heatwaves that occurred during this time, researchers looked at data from June 2019 to September 2019.

Researchers looked at the relationship between a person’s weight and the outside temperature on the day in question as well as the temperature two days before.

 Managing cardiac disease during periods of excessive heat

According to the experts, the strain brought on by a heatwave causes persons with heart failure to gain or lose weight. Deterioration of their clinical state may eventually be indicated by the change in weight.

The complicated physiological homeostasis that patients who are ordinarily maintaining a careful balance with heart failure are attempting to maintain may be impacted by temperature fluctuation. It would seem logical to predict that temperature will have a significant impact on how some [individuals] feel because of impacts on blood vessel size, compliance, and electrolyte balances. In certain cases, [individuals]’ conditions can be rather brittle.
