Hospitalization and death in elderly patients with heart failure could be associated with changes in temperature and atmospheric pressure. Elderly with heart failure should avoid fog and low cloud in the winter to prevent heart failure. Weather changes can affect the health of vulnerable people; heat waves and cold spells have been shown to increase disease and even lead to death in some people.
Researchers assessed some people aged 65 years and older that had been diagnosed with heart failure. The participants were followed for two years. During this time, the researchers measured the mean temperature, relative humidity, atmospheric pressure and air pollutants in the surrounding environment and studied the data to see if there was an association.
The results showed a higher risk of hospitalization or death in the winter period of the year compared to the summer period, they also found that the risk of heart failure incident increased with increase in atmospheric pressure.
A drop of 10°C in the average temperature over seven days, which is common in several countries because of seasonal variations, is associated with an increased risk in being hospitalized or dying of heart failure of about 7 percent in people aged over 65 diagnosed with the disease.
The study suggests that exposure to cold or high-pressure weather could trigger events leading to hospitalization or death in heart failure patients. This means that they should avoid exposure to fog and low cloud weather in winter as they often accompany high pressure.
The study reveals the impact of changes in temperature and air pressure on heart failure patients. Exposure to cold or high-pressure weather could trigger events leading to hospitalization or death in heart failure patients.
