Objective: This pilot study aimed to compare metabolic disturbances, particularly insulin resistance (IR) and cardiovascular risk factors (CRFs), following two types of acute vascular atherothrombotic disease events: ischaemic atherothrombotic stroke (AS); and acute coronary syndrome (ACS).
Design and methods: A total of 110 non-diabetic patients presenting with either AS (n=55) or ACS (n=55) were included in our prospective comparative study, and matched for age and gender. IR was determined using the homoeostasis model assessment of insulin resistance (HOMA-IR) method, and each patient's personal and family history were also recorded.
Results: IR was significantly higher in the ACS vs AS group (HOMA-IR index 2.17±1.90 vs 1.50±0.81, respectively; P=0.03). The AS group had a significantly higher prevalence of personal history of hypertension (51% vs 31%; P=0.03), while current smoking was more prevalent in the ACS group (30% vs 18%; P=0.04). There were no significant differences between the two groups as regards any other CRFs.
Conclusion: The distribution of CRFs varied depending on the vascular event, and metabolic disturbances differed according to the atherothrombotic disease. IR was greater after ACS than AS.
