Background: Subarachnoid haemorrhage (SAH) accounts for 5–10% of strokes and its prognosis may be influenced by different complications, including delayed cerebral ischaemia (DCI). The pathophysiology of DCI is complex and still unknown. Many different mechanisms may contribute to the occurrence of DCI. Arterial stiffness (AS), a well-known risk factor for cardiovascular events, also associated with the development and rupture of cerebral aneurysms, may represent a novel contributing risk factor. The aim of our study was to investigate a possible link between AS and DCI after SAH. Method: Fifty-nine (59) patients with SAH (age [mean±standard deviation], 62±12 years) underwent neuroimaging examination, and 24-hour heart rate and blood pressure monitoring, including AS index (ASI) measurement. Results: Of 59 patients, DCI occurred in 12. ASI was significantly higher in patients with DCI than in patients without it (0.70±0.1 vs 0.62±0.1; p=0.03). ASI was a significant predictor for DCI (odds ratio [for an increase of 0.20 points in ASI], 5.99; 95% confidence interval, 1.23–29.22; p=0.03). Conclusions: Arterial stiffness index is a simple and inexpensive tool that is able to predict the risk of DCI in patients with SAH. This marker can impact on intensive care unit monitoring, early recognition, and treatment, contributing to optimal acute management of patients with SAH.

Abstract
Background: Subarachnoid haemorrhage (SAH) accounts for 5–10% of strokes and its prognosis may be influenced by different complications, including delayed cerebral ischaemia (DCI). The pathophysiology of DCI is complex and still unknown. Many different mechanisms may contribute to the occurrence of DCI. Arterial stiffness (AS), a well-known risk factor for cardiovascular events, also associated with the development and rupture of cerebral aneurysms, may represent a novel contributing risk factor. The aim of our study was to investigate a possible link between AS and DCI after SAH. Method: Fifty-nine (59) patients with SAH (age [mean±standard deviation], 62±12 years) underwent neuroimaging examination, and 24-hour heart rate and blood pressure monitoring, including AS index (ASI) measurement. Results: Of 59 patients, DCI occurred in 12. ASI was significantly higher in patients with DCI than in patients without it (0.70±0.1 vs 0.62±0.1; p=0.03). ASI was a significant predictor for DCI (odds ratio [for an increase of 0.20 points in ASI], 5.99; 95% confidence interval, 1.23–29.22; p=0.03). Conclusions: Arterial stiffness index is a simple and inexpensive tool that is able to predict the risk of DCI in patients with SAH. This marker can impact on intensive care unit monitoring, early recognition, and treatment, contributing to optimal acute management of patients with SAH.File | Dimensione | Formato | |
