Background: The Osborn wave (OW) is often observed in hypothermic patients; however, whether OW in hypothermic patients is related to the development of fatal ventricular arrhythmia, including ventricular fibrillation (VF) and pulseless ventricular tachycardia (VT), remains undetermined. This study aimed to estimate the association between OW and the incidence of fatal ventricular arrhythmias.Methods and Results: This retrospective study used the Japanese Accidental Hypothermia Network registry database and included 572 hypothermic patients. Patients were divided into the OW group (those with OW) and non-OW group (those without OW). The relationship between the development of fatal arrhythmias and presence of OW was assessed using the chi-squared test. All patients who developed VF/VT (n=10) had OW on electrocardiogram upon hospital arrival. The presence of OW had a sensitivity of 100%, specificity of 47.8%, positive predictive value of 4.0%, and negative predictive value of 100% for VF/VT development. The in-hospital mortality rate was 22.3% in the OW group and 21.2% in the non-OW group (P=0.781).Conclusions: OW was observed in all hypothermic patients with VF/VT. The occurrence of ventricular arrhythmias is highly unlikely in the absence of OW on the electrocardiogram. Although the presence of OW might be used to predict these fatal arrhythmias in hypothermic patients, there was no association between the presence of OW and in-hospital mortality.

In Japan, which has a super-aging society, there are increasing opportunities to perform mechanical thrombectomy for the elderly; however, there is no recorded evidence of thrombectomy for the elderly. This study examined the usefulness of thrombectomy in the elderly. We retrospectively analyzed patient data using a multicenter acute ischemic stroke registry (NGT-FAST). We examined outcomes in patients 75 years and older who underwent thrombectomies between January 1, 2021, and December 31, 2021. The patients were divided into two groups: the 75-84-year-old group and the 85+-year-old group. There was no difference in the pretreatment National Institutes of Health Stroke Scale score or Alberta Stroke Program Early Computed Tomography Score between the two groups, but the 85+-year-old group had a significantly lower rate of pre-stroke modified Rankin Scale (mRS) score of 0-2. There were no differences in time from onset to treatment or effective recanalization rate, but complications tended to be more common in the 85+-year-old group. The number of patients with a good outcome at discharge (an mRS score of 0-3) was significantly lower in the 85+-year-old group than in the 75-84-year-old group. In addition, 90.9% of patients in the 85+-year-old group with a pre-stroke mRS score of 3 deteriorated after treatment. The pre-stroke mRS score is very important in determining the indication for thrombectomy in the elderly because their preoperative condition is more likely to influence the outcome than that of younger patients.
