Heart problems increased due to rise in temperature, global warming continues

Scientists have claimed that with the rise in Earth’s temperature and global warming, heart diseases will get worse.

In a new study, scientists said that during the 2019 heatwave, warmer temperatures and global warming were closely associated with weight loss in heart failure patients, indicating a worsening of their condition.

The study focused on the relationship between ambient temperature and body weight in heart failure patients.

Study author Professor François Rubil from Montpellier University Hospital in France said: “The amount of weight we lost in people with heart failure can lead to low blood pressure, especially on standing, and kidney failure, and potentially is life-threatening. With rising temperatures forecast for the foreseeable future, physicians and patients should be prepared to reduce the dose of diuretics if weight loss occurs.”

Symptoms of heart failure:

The study noted that when a patient has heating failure, the heart no longer pumps blood around the body, and waste products accumulate, causing shortness of breath and in the lungs, legs, and abdomen. fluid is formed. Weight is a cornerstone of monitoring because weight gain is related to congestion, which is the main cause of hospitalization.

How does diuretic help?

Diuretics, also called water chestnuts, are used to increase urine output and reduce breathlessness and bloating. According to the European Society of Cardiology (ESC), patients need to be educated about increasing their diuretic dose or alerting their health team if they experience shortness of breath or an increase in swelling or a sudden drop of 2 kg in three days. Experiencing more weight gain.

Professor Rubil explained: “When healthy people drink more fluids during hot weather, the body automatically regulates urine output. This does not apply to patients with heart failure as they take diuretics.”

How was the study conducted?

The analysis included 1,420 patients with chronic heart failure. The mean age of the participants was 73 years, 28% were female, and the mean weight was 78 kg.

The study examined the relationship between body weight and air temperature between 1 June and 20 September 2019, covering two heatwaves in late June and late July.

Patients weighed themselves every day using a connected weighing scale that automatically sends measurements to the clinic. Patients reported daily symptoms such as edema, fatigue, breathlessness and cough by answering questions on a personal device (eg smartphone, tablet), answers to which were automatically sent to the clinic.

The relationship between temperature and weight was very strong, with weight falling as temperature increased.

Professor Rubil said: “The weight we lost during the summer was clinically relevant. Patients weighing 78 kg lost 1.5 kg in a short period of time. We were surprised to see that the weight loss decreased with warmer temperatures, As we expected the opposite.

He added that if the weight is reduced by 2 kg during the heatwave then a good rule of thumb would be to contact a health professional for advice on adjusting diuretic medication.
