Weather Conditions May Influence the Risk of Heart Attacks

Changes in weather conditions may increase the likelihood of developing Myocardial Infarction. This conclusion was reached by researchers who analyzed the relationship between meteorological factors and the frequency of heart attacks using machine-learning methods. The results were published in the journal Frontiers in Cardiovascular Medicine.

Scientists studied data from 11,527 patients who suffered heart attacks over a ten-year period at a cardiology center in Beijing. These records were compared with daily meteorological indicators.

The analysis showed that days with a higher number of heart attacks more often coincided with lower air temperatures, large day-to-day temperature fluctuations, weak wind, as well as lower humidity and minimal precipitation.

Using the Random Forest model, the researchers identified the key weather parameters associated with an increased risk of heart attacks. The most significant factor turned out to be the daily temperature variation, which had the strongest influence on the likelihood of a rise in cases.

According to the study’s authors, such predictive models could help healthcare systems anticipate periods of increased strain on cardiology services and distribute medical resources more effectively. In the future, the researchers plan to improve the accuracy of their forecasts by adding data on patients’ age, comorbidities, and other individual characteristics to the weather information.
