Introduction: stroke recurrence in patients with TIA is one of the most frustrating medical situations and it is very important to identify strong predictors of stroke recurrence to enable practitioners to take clinical decisions
Hypothesis: to evaluate the relationship between pulse pressure (PP), a marker of vascular disease, and the risk of stroke recurrence in patients with TIA.
Methods: TIA patients were prospectively included in a multidisciplinary secondary stroke prevention program. Pre-stroke vascular risk factor profile and control were obtained from electronic medical records. Stroke recurrence was analyzed after five years of follow up. For the purpose of the analysis, three groups were defined according to pre-stroke PP: < 60, 60-69 and > 70 mmHg.
Results: 357 patients (mean age 75±10 years, 55% females) were included. Vascular risk factors profile: hypertension 83%, dislipidemia 74%, obesity 54%, smoking 41%, diabetes 12%, AF 12%, CKD 28%, CHD 18%. Mean SBP was 130 mmHg and DBP 80 mmHg; 78% was receiving antihypertensives, 47% statins, 43% antiplatelets and 9% anticoagulants before the event. There was a direct relationship between pre-stroke PP and stroke recurrence during follow-up (figure).
Conclusion: PP is related to higher burden of vascular disease, mainly an increase in arterial stiffness, which might be a key element in clinical decision making in the setting of stroke recurrence prevention.
