Heart endangered in summer nights. After sunset, during the hot season, the number of heart attacks increases. This is evident from a study published in the Journal of the American Heart Association, and to Enrico Ammirati, cardiologist at the De Gasperis Cardio Center of the Niguarda of Milan and co-principal investigator of the study, along with Carlo Vittorio Cannistraci of Max Planck Institute participated by Dresden. "In this article, in which we examined how seasonality affects the spread of infarct beginning, it was highlighted how summer nights have a greater number of events than winter nights," he explains. Ammirati.
"The phenomenon is related to" Stemi "heart attack, ie those with a specific abnormality in the electrocardiogram trace, a signal for acute and total coronary obstruction.Technically, the relative increase in the number of nocturnal myocardial infarctions compared to heart attacks in the summer In comparison to the other seasons, the study points out that "to determine the variation in the relationship between daytime and night-time infarcts" would be the intensity of light during the day rather than its duration Equator does not have a real summer season), for example – as shown in the research reports – the "shift" on less cloudy days: in fact, those in which the sunlight was more intense ".
"We have tried to examine the" dark side of the moon ", ie those possible phenomena or relationships that link the onset of a myocardial infarction with complex natural events such as chronobiology – explains Ammirati Researchers were awarded the Nobel Prize for Medicine, which explored the molecular mechanisms underlying our biorhythms, the circadian rhythms.We already knew that there are more heart attacks in the winter than in the summer, and that the time of day is the highest Heart attacks early in the morning. "The Cardio Center's research is supported by the De Gasperis Foundation, which, on 23 September, will be bringing together the leading experts at the National Cardiology Conference in Milan, as it has for 53 years.
