Over the past 25 years, mortality from heart failure has decreased in Sweden. As reported in the European Journal of Heart Failure, the decline was greater among patients with a reduced left ventricular ejection fraction than among those with a preserved ejection fraction. Between 1997 and 2022, the age-adjusted mortality from heart failure in the population decreased from 33.4 to 23.8 per 100,000 people (-2.15 percent, p < 0.001). Heart failure is considered to affect 2–3 percent of people worldwide. Although doctors have made significant progress in adjusting risk factors for this disease in recent decades, recent data from developed countries show a sharp increase in mortality among patients with heart failure. Therefore, a team of scientists led by Gianluigi Savarese from the Karolinska Institutet assessed time trends in heart failure-related mortality in the general population of the country. All-cause mortality at 1, 3, and 5 years after first diagnosis was 25, 46, and 58 percent, respectively, in 2022.
