Resumption of oral anticoagulation after spontaneous intracerebral hemorrhage.

ABSTRACT:

Background

Given an ageing population the incidence of both patients suffering from intracerebral hemorrhage (ICH) and those requiring oral anticoagulation will increase. Up to now there are no results from randomized trials available whether or not, and when, ICH survivors should resume OAC. This review summarizes the most important observational studies, and initiated ongoing trials, to help guiding physicians in daily routine decision making.

Findings

Several large observational studies and meta-analyses verified that OAC resumption was associated with a significant reduction of thromboembolic complications and mortality without leading to increased rates of recurrent ICH. OAC resumption seemed further associated with improved functional recovery and favorable long-term outcome. Given the general bleeding risk reduction in patients using Non-vitamin K antagonist oral anticoagulants (NOAC) compared to Vitamin-K-antagonist (VKA), NOAC use should also be preferred after ICH, although specific comparative studies are pending. Patients with lobar ICH need special attention as these patients showed increased ICH recurrence rates, why decision making should include extended diagnostic work-up evaluating cerebral microbleed burden, cortical subarachnoid hemorrhage and superficial siderosis. Further, patients with mechanical heart valves need specific consideration as restarting VKA may be unsafe until two weeks, whereas optimal balancing of hemorrhagic with thromboembolic complications may allow earlier re-initiation one week after ICH. In patients with atrial fibrillation, resumption generally should take place between 4 and 8?weeks after ICH depending on a patient's individual risk profile. Left atrial appendage occlusion (LAAO) might represent an alternative strategy in high-risk patients. Ongoing clinical trials will clarify whether OAC resumption versus LAAO versus no antithrombotic therapy may represent the best possible secondary stroke prevention in ICH survivors with atrial fibrillation.

Conclusions

According to observational data OAC resumption after ICH seems beneficial and safe. Ongoing clinical trials will create evidence regarding treatment effects of pharmaceutical resumption and interventional alternatives. Yet, individual decision making weighing the patient's individual thromboembolic versus hemorrhagic risks remains essential.

Project description:BackgroundPatients with mechanical heart valves are usually maintained on anticoagulation therapy. However, after a spontaneous intracerebral hemorrhage event, administration of anticoagulants is temporarily ceased, and it remains unclear when to restart anticoagulation therapy.MethodsA cohort study was conducted to investigate the optimal time for restarting anticoagulation in patients with mechanical heart valves after spontaneous intracerebral hemorrhage. All patients with mechanical valves who experienced spontaneous cerebral hemorrhage and were admitted to the Second Affiliated Hospital of the Zhejiang University Medical School between 2013 and 2018 were retrospectively enrolled in this study. The patient electronic medical records were reviewed and the correlation between the time of restarting anticoagulation (within 3 days or more than 3 days after hemorrhage) and patient prognosis was assessed.ResultsA total of 40 patients with mechanical heart valves who experienced spontaneous cerebral hemorrhage were enrolled in this study. All patients were given oral warfarin anticoagulant therapy prior to admission (1.5-3.25 mg). After admission, patients were administered fresh frozen plasma and/or vitamin K1 to reverse anticoagulation. Out of the 16 patients (40%) who underwent surgical intervention, 4 died from cerebral hemorrhage deterioration during the hospital stay and did not restart anticoagulant therapy. Anticoagulant therapy was resumed within 3 days for 18 patients and more than three days after hemorrhage for the other 18 patients. After discharge, patients were followed up for 12 months or more. Unfortunately, during this period, 17% of patients (6/36) died.ConclusionsDefinitive hemostatic measures can be as an important factor in the clinical resumption of anticoagulation. Halting anticoagulant therapy for 3 to 7 days may be safe. It is recommended that low molecular heparin be administered within 3 days as a bridge treatment, combine with warfarin anticoagulant therapy within 1 week after hemorrhage.

Project description:ImportanceLimited evidence is available concerning optimal seizure prophylaxis after spontaneous intracerebral hemorrhage (sICH).ObjectiveTo evaluate which of 4 seizure prophylaxis strategies provides the greatest net benefit for patients with sICH.Design, setting, and participantsThis decision analysis used models to simulate the following 4 common scenarios: (1) a 60-year-old man with low risk of early (≤7 days after stroke) (10%) and late (3.6% or 9.8%) seizures and average risk of short- (9%) and long-term (30%) adverse drug reaction (ADR); (2) an 80-year-old woman with low risk of early (10%) and late (3.6% or 9.8%) seizures and high short- (24%) and long-term (80%) ADR risks; (3) a 55-year-old man with high risk of early (19%) and late (34.8% or 46.2%) seizures and low short- (9%) and long-term (30%) ADR risks; and (4) a 45-year-old woman with high risk of early (19%) and late (34.8% or 46.2%) seizures and high short- (18%) and long-term (60%) ADR risks.InterventionsThe following 4 antiseizure drug strategies were included: (1) conservative, consisting of short-term (7-day) secondary early-seizure prophylaxis with long-term therapy after late seizure; (2) moderate, consisting of long-term secondary early-seizure prophylaxis or late-seizure therapy; (3) aggressive, consisting of long-term primary prophylaxis; and (4) risk guided, consisting of short-term secondary early-seizure prophylaxis among low-risk patients (2HELPS2B score, 0), short-term primary prophylaxis among patients at higher risk (2HELPS2B score, ≥1), and long-term secondary therapy for late seizure.Main outcomes and measuresQuality-adjusted life-years (QALYs).ResultsFor scenario 1, the risk-guided strategy (8.13 QALYs) was preferred over the conservative (8.08 QALYs), moderate (8.07 QALYs), and aggressive (7.88 QALYs) strategies. For scenario 2, the conservative strategy (2.18 QALYs) was preferred over the risk-guided (2.17 QALYs), moderate (2.09 QALYs), and aggressive (1.15 QALYs) strategies. For scenario 3, the aggressive strategy (9.21 QALYs) was preferred over the risk-guided (8.98 QALYs), moderate (8.93 QALYs), and conservative (8.77 QALYs) strategies. For scenario 4, the risk-guided strategy (11.53 QALYs) was preferred over the conservative (11.23 QALYs), moderate (10.93 QALYs), and aggressive (8.08 QALYs) strategies. Sensitivity analyses suggested that short-term strategies (conservative and risk guided) are preferred under most scenarios, and the risk-guided strategy performs comparably to or better than alternative strategies in most settings.Conclusions and relevanceThis decision analytical model suggests that short-term (7-day) prophylaxis dominates longer-term therapy after sICH. Use of the 2HELPS2B score to guide clinical decisions for initiation of short-term primary vs secondary early-seizure prophylaxis should be considered for all patients after sICH.
