A study by HUS (Helsinki University Hospital) has highlighted that the majority of heart attacks, or myocardial infarctions, can be prevented through healthy lifestyle choices. Despite the gradual decrease in new heart attack cases since the mid-1990s in both men and women, an alarming rise has been observed among women aged 35-54. This increase, according to Professor Juha Sinisalo, a Cardiology Professor at the Heart and Lung Center, might be linked to the growing prevalence of obesity.
