AI Summary

Researchers from the MPIDR and Karolinska Institute analyzed Swedish registry data spanning 1987‑2022 to track new cases of heart attacks, strokes, hip fractures and malignant cancers among people aged 60‑90. Using birth cohorts born between 1904 and 1960, they calculated age‑specific incidence rates, one‑ and five‑year survival proportions, and disease prevalence at ages 70, 80 and 90. Their findings show that acute heart attacks, once nearly always fatal, now have markedly higher survival rates, while cancer incidence has risen but survival chances have improved. The study quantifies how disease prevention has reshaped health outcomes across multiple conditions in Sweden.
