Popis: Abstract Aims Despite adequate treatment, recent studies have hypothesized that malaria may affect long‐term cardiovascular function. We aimed to investigate the long‐term risk of cardiovascular events and death in individuals with a history of imported malaria in Denmark. Methods Using nationwide Danish registries, we followed individuals with a history of malaria for the risk of incident heart failure (HF), myocardial infarction (MI), cardiovascular death and all‐cause death (1 January 1994 to 1 January 2017). The population was age‐ and sex‐matched with individuals without a history of malaria from the Danish population (ratio 1:9). We excluded patients with known HF and ischaemic heart disease at inclusion. Results We identified 3912 cases with a history of malaria (mean age 33 ± 17 years, 57% male, 41% Plasmodium falciparum infections). The median follow‐up was 9.8 years (interquartile range 3.9–16.4 years). Event rates per 1000 person‐years for individuals with a history vs. no history of malaria were HF: 1.84 vs. 1.32; MI: 1.28 vs. 1.30; cardiovascular death: 1.40 vs. 1.77; and all‐cause death: 5.04 vs. 5.28. In Cox proportional hazards models adjusted for cardiovascular risk factors, concomitant pharmacotherapy, region of origin, household income and educational level, malaria was associated with HF (HR: 1.59 [1.21–2.09], P = 0.001), but not MI (HR: 1.00 [0.72–1.39], P = 1.00), cardiovascular death (HR: 1.00 [0.74–1.35], P = 0.98) or all‐cause death (HR 1.11 [0.94–1.30], P = 0.21). Specifically, P. falciparum infection was associated with increased risk of HF (HR: 1.64 [1.14–2.36], P = 0.008). Conclusion Individuals with a history of imported malaria, specifically P. falciparum, may have an increased risk of incident HF.
