BACKGROUND: Strokes in the young and middle-aged are associated with a disproportionately large economic and social impact in addition to their clinical effects. Standard Modifiable Cardiovascular Risk Factors (SMuRFs; hypercholesterolaemia, hypertension, diabetes mellitus and smoking) are key drivers of cardiovascular disease including strokes, however recent temporal trends in the younger stroke population have not been well characterised. We aimed to evaluate recent trends of SMuRFs in a cohort of younger patients with ischaemic stroke.
METHODS: Consecutive patients aged <65 years with clinical and/or radiological diagnosis of ischaemic stroke or transient ischaemic attack in a tertiary referral centre (2013-2017) were retrospectively appraised. The demographic and clinical comorbidities of these patients were assessed including their SMuRF profile. The prevalence over time and clinical associations of patients with no SMuRFs were studied and compared to patients with SMuRFs.
RESULTS: Of 487 patients (53.49 ± 9.13 yrs., 60% men) analysed, 23% did not have SMuRFs. The proportion of "non-SMuRF" patients increased over time (p < 0.01) and this trend was not influenced by age (p = 0.48) or gender (p = 0.68). The presence of SMuRFs was not associated with in-hospital outcomes, however patients without SMuRFs were significantly less likely to be discharged on blood pressure (p < 0.01) and lipid-lowering therapies (p = 0.03).
CONCLUSIONS: The proportion of younger stroke patients without SMuRFs is substantial and has increased over time. Our findings highlight the need for further research to better understand the mechanisms underlying stroke development in this population and whether less risk factor treatment in this population could impact longer term outcomes.
