Introduction and aim: Hemorrhagic transformation (HT) is the most feared complication in acute phase of ischemic stroke. Predicting HT is of utmost importance in clinical practice. In the latest years a lot of HT prediction scores have been proposed, but their comparison in real life lack. Therefore, the aim of our study was to provide information about this topic. Materials and Methods: We retrospectively calculated THRIVE, SPAN-100, MSS score, SITS-ICH and GRASPS scores in patients consecutively admitted in our Stroke Unit along two years. To evaluate their predictive power, the area under the curve (AUC) of the Receiver Operating Characteristic (ROC) curve was calculated. Results: Study population was composed by ninety-one patients (51.6% females) with mean age 80.1 ± 11.3 years. Seventy-four (81.3%) patients undergone to systemic intravenous alteplase, seven (7.7%) to mechanical thrombectomy, ten (11%) to systemic intravenous alteplase plus mechanical thrombectomy. Eighteen patients (19.7%) presented HT. MSS score was the best prognosticator of HT, however the predictive power of the five analyzed score was low, ranging from and none of the score resulted significantly superior to the others. Conclusion: Our real-life study showed a low predictive power of a lot of HT prediction scores. Further prospective studies are warranted.
Predicting hemorrhagic transformation (HT) in stroke patients undergone to urgent reperfusion by intravenous thrombolysis and/or mechanical thrombectomy is of utmost importance in clinical practice. In 2017, a scientific statement for healthcare professionals from the American Heart Association/American Stroke Association identified seven validated scores for predicting HT in clinical practice [1-8]. All these seem to have a similar predictive power, C statistic ranging from about 0.50 to 0.86. National Institute of Health Stroke Scale (NIHSS) score is the only one variable present in all seven scores, while age is present in six of seven scores. Other variables present in the majority of scores are high glucose levels and blood hypertension [1]. Literature lacks about comparison between these prediction score in real life patients, therefore the aim of our study was to compare the power of HT prediction scores.
We retrospectively analyzed clinical, instrumental and laboratory data of patients with acute ischemic stroke consecutively admitted to our Stroke Unit along two years, from November 1st 2017 to November 1st 2019, and undergone to sistemi thrombolysis and/or mechanical thrombectomy. For all patients we calculated five of the seven HT prediction scores proposed by ASA/AHA: THRIVE score [7], SPAN-100 score [8], MSS score [2], SITS-ICH score [5] and GRASPS score [6] (see Table 1 for characteristics of each score). To evaluate their predictive power, the area under the curve (AUC) of the Receiver Operating Characteristic (ROC) curve was calculated. All analyses were performed using MEDCALC statistical software (MedCalc Software Ltd, Acacialaan 22, B-8400 Ostend, Belgium).
Study population was composed by ninety-one patients (51.6
HT represents the most feared complication of urgent reperfusion in acute stroke patients and it is associated to reduced neurological improvement or deterioration [9]. Therefore, predict or prevent HT is fundamental. Despite the prediction scores are effective at estimating the HT risk, in clinical practice it's not justified withholding urgent reperfusion treatment in patients with high HT scoring. Many HT predictions scores have been proposed [2-8] in the past decade and others have been recently proposed [10-12]. These could help to select high HT risk patients requiring a closer monitoring. Despite limitations due to retrospective methodology, single center and limited sample size, our real-life study showed a low predictive power of a lot of HT prediction scores. Further prospective studies are warranted.
