Abstract | Acetylsalicylic acid (ASA) is widely used in secondary prevention of cardiovascular (CV) disease, mainly because of its antithrombotic effects. Here, we investigated whether ASA can prevent the progression of vessel wall remodelling, atherosclerosis, and CV complications in apolipoprotein E deficient ( ApoE −/− ) mice, a model of stable atherosclerosis, and in ApoE −/− mice with a mutation in the fibrillin-1 gene ( Fbn1 C1039G+/− ), which is a model of elastic fibre fragmentation, accompanied by exacerbated unstable atherosclerosis. Female ApoE −/− and ApoE −/− Fbn1 C1039G+/− mice were fed a Western diet (WD). At 10 weeks of WD, the mice were randomly divided into four groups, receiving either ASA 5 mg/kg/day in the drinking water ( ApoE −/− ( n = 14), ApoE −/− Fbn1 C1039G+/− ( n = 19)) or plain drinking water ( ApoE −/− ( n = 15), ApoE −/− Fbn1 C1039G+/− ( n = 21)) for 15 weeks. ApoE −/− Fbn1 C1039G+/− mice showed an increased neutrophil–lymphocyte ratio (NLR) compared to ApoE −/− mice, and this effect was normalised by ASA. In the proximal ascending aorta wall, ASA-treated ApoE −/− Fbn1 C1039G+/− mice showed less p-SMAD2/3 positive nuclei, a lower collagen percentage and an increased elastin/collagen ratio, consistent with the values measured in ApoE −/− mice. ASA did not affect plaque progression, incidence of myocardial infarction and survival of ApoE −/− Fbn1 C1039G+/− mice, but systolic blood pressure, cardiac fibrosis and hypertrophy were reduced. In conclusion, ASA normalises the NLR, passive wall stiffness and cardiac remodelling in ApoE −/− Fbn1 C1039G+/− mice to levels observed in ApoE −/− mice, indicating additional therapeutic benefits of ASA beyond its classical use. |
