Cause of death in spontaneous intracerebral hemorrhage survivors

ObjectiveTo determine the leading causes of death in intracerebral hemorrhage (ICH) survivors, we used administrative data from 3 large US states to identify adult survivors of a first-time spontaneous ICH and track all hospital readmissions resulting in death.MethodsWe performed a longitudinal analysis of prospectively collected claims data from hospitalizations in California (2005–2011), New York (2005–2014), and Florida (2005–2014). Adult residents admitted with a nontraumatic ICH who survived to discharge were included. Patients were followed for a primary outcome of any readmission resulting in death. The cause of death was defined as the primary diagnosis assigned at discharge. Multivariable Cox proportional hazards and multinomial logistic regression were used to determine factors associated with the risk for and cause of death.ResultsOf 72,432 ICH survivors (mean age 68 years [SD 16], 48% female), 12,753 (18%) died during a median follow-up period of 4.0 years (interquartile range 2.3–6.3). The leading causes of death were infection (34%), recurrent intracranial hemorrhage (14%), cardiac disease (8%), respiratory failure (8%), and ischemic stroke (5%). Death in patients with atrial fibrillation (AF) was more likely to be caused by ischemic stroke (odds ratio [OR] 2.4, 95% confidence interval [CI] 1.9–2.9, p < 0.001) and less likely to be caused by recurrent intracranial hemorrhage (OR 0.7, 95% CI 0.6–0.8, p < 0.001) compared to patients without AF.ConclusionsInfection is the leading cause of death in all ICH survivors. Survivors with AF were at increased risk for death from ischemic stroke. These findings will help prioritize interventions aimed to improve long-term survival and recovery in ICH survivors.

Thrombotic Complications

Introduction: Liver cirrhosis is characterized by a coagulopathy associated with both hemorrhagic and thrombotic complications. However, the risk of stroke - hemorrhagic and ischemic - in patients with cirrhosis has not been rigorously assessed. Methods: We performed a retrospective cohort study of Medicare beneficiaries ≥66 years of age using a 5% sample of inpatient and outpatient claims from 2008-2014. Our predictor was liver cirrhosis, defined by presence of at least two ICD-9-CM inpatient or outpatient claims for liver cirrhosis or its complications, a validated algorithm previously used to study cirrhosis in Medicare beneficiaries. The primary outcome was stroke, and the secondary outcomes were ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage. Outcomes were defined by validated ICD-9-CM algorithms. Patients were censored at the time of an outcome, death, or on December 31, 2014. We used survival analysis to compare stroke incidence in patients with and without liver cirrhosis. Cox proportional hazards analysis was used to evaluate the association between cirrhosis and stroke while adjusting for demographics and established stroke risk factors. Results: Among the 1,564,277 beneficiaries in our sample, we identified 10,512 (0.7%) patients with liver cirrhosis. The mean age of patients with cirrhosis was 74.1 (±6.5) years. Over a median follow-up of 5 years, 76,195 patients were hospitalized with a stroke. The incidence of stroke was 1.9% (95% confidence interval [CI], 1.7-2.1%) per year in patients with cirrhosis and 1.1% (95% CI, 1.1-1.1%) per year in patients without cirrhosis. After adjusting for demographics and vascular risk factors, patients with cirrhosis experienced a higher risk of stroke (hazard ratio [HR], 1.4; 95% CI, 1.2-1.5); however, associations appeared more robust for intracerebral hemorrhage (HR, 2.2; 95% CI, 1.7-2.8) and subarachnoid hemorrhage (HR, 2.0; 95% CI, 1.2-3.1) than for ischemic stroke (HR, 1.3; 95% CI, 1.1-1.4). Conclusions: We found that liver cirrhosis was associated with an increased risk of stroke, particularly hemorrhagic stroke. Our results build on recent work investigating the hemorrhagic and thrombotic complications of liver cirrhosis outside of the portal circulation.

Background and Purpose: Data on long-term survival after intracerebral hemorrhage (ICH) are scarce. In a population-based nested case-control study, we compared long-term survival and causes of death within 5 years in 30-day survivors of first-ever ICH and controls, assessed the impact of cardiovascular risk factors on 5-year mortality, and analyzed time trend in 5-year mortality in ICH patients over 2 decades. Methods: We included 219 participants from the population-based Tromsø Study, who after the baseline participation had a first-ever ICH between 1994 to 2013 and 1095 age- and sex-matched participants without ICH. Cumulative survival was presented using the Kaplan-Meier method. Hazard ratios (HRs) for mortality and for the association between cardiovascular risk factors and 5-year mortality in 30-day survivors were estimated by stratified Cox proportional hazards models. Trend in 5-year mortality was assessed by logistic regression. Results: Risk of death during follow-up (median time, 4.8 years) was increased in the ICH group compared with controls (HR, 1.62 [95% CI, 1.27–2.06]). Cardiovascular disease was the leading cause of death, with a higher proportion in ICH patients (22.9% versus 9.0%; P <0.001). Smoking increased the risk of 5-year mortality in cases and controls (HR, 1.59 [95% CI, 1.15–2.19]), whereas serum cholesterol was associated with 5-year mortality in cases only (HR, 1.39 [95% CI, 1.04–1.86]). Use of anticoagulants at ICH onset increased the risk of death (HR, 2.09 [95% CI, 1.09–4.00]). There was no difference according to ICH location (HR, 1.15 [95% CI, 0.56–2.37]). Five-year mortality did not change during the study period (odds ratio per calendar year, 1.01 [95% CI, 0.93–1.09]). Conclusions: Survival rates were significantly lower in cases than in controls, driven by a 2-fold increased risk of cardiovascular death. Smoking, serum cholesterol, and use of anticoagulant drugs were associated with increased risk of death in ICH patients. Five-year mortality rates in ICH patients remained stable over time.

AbstractInfection by the new corona virus strain SARS-CoV-2 and its related syndrome COVID-19 has been associated with more than two million deaths worldwide. Patients of higher age and with preexisting chronic health conditions are at an increased risk of fatal disease outcome. However, detailed information on causes of death and the contribution of pre-existing health conditions to death yet is missing, which can be reliably established by autopsy only. We performed full body autopsies on 26 patients that had died after SARS-CoV-2 infection and COVID-19 at the Charité University Hospital Berlin, Germany, or at associated teaching hospitals. We systematically evaluated causes of death and pre-existing health conditions. Additionally, clinical records and death certificates were evaluated. We report findings on causes of death and comorbidities of 26 decedents that had clinically presented with severe COVID-19. We found that septic shock and multi organ failure was the most common immediate cause of death, often due to suppurative pulmonary infection. Respiratory failure due to diffuse alveolar damage presented as immediate cause of death in fewer cases. Several comorbidities, such as hypertension, ischemic heart disease, and obesity were present in the vast majority of patients. Our findings reveal that causes of death were directly related to COVID-19 in the majority of decedents, while they appear not to be an immediate result of preexisting health conditions and comorbidities. We therefore suggest that the majority of patients had died of COVID-19 with only contributory implications of preexisting health conditions to the mechanism of death.

Large Vessel Stroke

Introduction The International Stroke Genetics Consortium (ISGC) and the Wellcome Trust Case Control Consortium 2 (WTCCC2) performed a large genome wide association study of ischemic stroke and its subtypes (large vessel stroke (LVD), small vessel stroke (SVD), cardioembolic stroke (CE)), and identified a polymorphism in HDAC9 (rs11984041) associated with the LVD subtype of ischemic stroke. Hypothesis We assessed the hypothesis that rs11984041 is associated with LVD in two additional studies. Methods The genotype of rs11984041 was determined for participants of the Vienna Study (815 controls, 122 LVD, 165 SVD, 202 CE) and of the German Study (1040 controls, 495 LVD, 230 SVD, 462 CE). The association of rs11984041 with LVD was assessed by logistic regression. Heterogeneity of the effect of rs11984041 on LVD, CE or SVD was assessed by testing the equality of the corresponding regression coefficients from a multinomial logistic regression model. Results Carriers of the minor (T) allele of rs11984041 (23.3% of LVD cases and 17.4% of controls), compared with noncarriers, had increased risk for LVD: the odds ratios (OR) were 1.92 (95%CI 1.25-2.96) for the Vienna Study and 1.33 (95%CI 1.02-1.74) for the German Study. Adjusting for covariates including sex, age, diabetes, and hypertension did not materially change the ORs. Heterogeneity of the effects of rs11984041 on LVD vs CE was significant in the Vienna Study (p = 0.009) and in the German Study (p = 0.005). Heterogeneity of the effects of rs11984041 on LVD vs SVD trended toward significance in the Vienna Study (p = 0.088) and was significant in the German Study (p = 0.047). Adjusting for covariates did not materially change the heterogeneity test p values. Conclusions The HDAC9 polymorphism rs11984041 was associated with the LVD stroke subtype in the Vienna Study and the German Study. These results replicated the ISGC/WTCCC2 findings.

Background and Purpose— Premature ventricular complexes (PVCs) detected from long-term ECG recordings have been associated with an increased risk of ischemic stroke. Whether PVCs seen on routine ECG, commonly used in clinical practice, are associated with an increased risk of ischemic stroke remains unstudied. Methods— This analysis included 24 460 participants (aged, 64.5+9.3 years; 55.1% women; 40.0% blacks) from the Reasons for Geographic and Racial Differences in Stroke (REGARDS) study who were free of stroke at the time of enrollment. PVCs were ascertained from baseline ECG (2003–2007), and incident stroke cases through 2011 were confirmed by an adjudication committee. Results— A total of 1415 (5.8%) participants had at least 1 PVC at baseline, and 591 developed incident ischemic stroke during an average (SD) follow-up of 6.0 (2.0) years. In a cox proportional hazards model adjusted for age, sex, race, geographic region, education, previous heart disease, systolic blood pressure, blood pressure–lowering medications, current smoking, diabetes mellitus, left ventricular hypertrophy by ECG, and aspirin use and warfarin use, the presence of PVCs was associated with 38% increased risk of ischemic stroke (hazard ratio [95% confidence interval], 1.38 [1.05–1.81]). Conclusions— PVCs are common on routine screening ECGs and are associated with an increased risk of ischemic stroke.

Background Cerebral microbleeds can confer a high risk of intracerebral hemorrhage, ischemic stroke, death and dementia, but estimated risks remain imprecise and often conflicting. We investigated the association between cerebral microbleeds presence and these outcomes in a large meta-analysis of all published cohorts including: ischemic stroke/TIA, memory clinic, “high risk” elderly populations, and healthy individuals in population-based studies. Methods Cohorts (with > 100 participants) that assessed cerebral microbleeds presence on MRI, with subsequent follow-up (≥3 months) were identified. The association between cerebral microbleeds and each of the outcomes (ischemic stroke, intracerebral hemorrhage, death, and dementia) was quantified using random effects models of (a) unadjusted crude odds ratios and (b) covariate-adjusted hazard rations. Results We identified 31 cohorts ( n = 20,368): 19 ischemic stroke/TIA ( n = 7672), 4 memory clinic ( n = 1957), 3 high risk elderly ( n = 1458) and 5 population-based cohorts ( n = 11,722). Cerebral microbleeds were associated with an increased risk of ischemic stroke (OR: 2.14; 95% CI: 1.58–2.89 and adj-HR: 2.09; 95% CI: 1.71–2.57), but the relative increase in future intracerebral hemorrhage risk was greater (OR: 4.65; 95% CI: 2.68–8.08 and adj-HR: 3.93; 95% CI: 2.71–5.69). Cerebral microbleeds were an independent predictor of all-cause mortality (adj-HR: 1.36; 95% CI: 1.24–1.48). In three population-based studies, cerebral microbleeds were independently associated with incident dementia (adj-HR: 1.35; 95% CI: 1.00–1.82). Results were overall consistent in analyses stratified by different populations, but with different degrees of heterogeneity. Conclusions Our meta-analysis shows that cerebral microbleeds predict an increased risk of stroke, death, and dementia and provides up-to-date effect sizes across different clinical settings. These pooled estimates can inform clinical decisions and trials, further supporting cerebral microbleeds role as biomarkers of underlying subclinical brain pathology in research and clinical settings.

BACKGROUND: Aortic arch plaques (AAP) are a risk factor for cardiovascular embolic events. However, the risk of vascular events associated with AAP in the general population is unclear. AIM: To assess whether AAP detected by transesophageal echocardiography (TEE) are associated with an increased risk of vascular events in a stroke-free cohort. METHODS: The study cohort consisted of stroke-free subjects over age 50 from the Aortic Plaques and Risk of Ischemic Stroke (APRIS) study. AAP were assessed by multiplane TEE, and considered large if ≥ 4 mm in thickness. Vascular events including myocardial infarction, ischemic stroke and vascular death were recorded during the follow-up. The association between AAP and outcomes was assessed by univariate and multivariate Cox proportional hazards models. RESULTS: A group of 209 subjects was studied (mean age 67±9 years; 45% women; 14% whites, 30% blacks, 56% Hispanics). AAP of any size were present in 130 subjects (62%); large AAP in 50 (24%). Subjects with AAP were older (69±8 vs. 63±7 years), had higher systolic BP (146±21 vs.139±20 mmHg), were more often white (19% vs. 8%), smokers (20% vs. 9%) and more frequently had a history of coronary artery disease (26% vs. 14%) than those without AAP (all p<0.05). Lipid parameters, prevalence of atrial fibrillation and diabetes mellitus were not significantly different between the two groups. During the follow up (94±29 months) 30 events occurred (13 myocardial infarctions, 11 ischemic strokes, 6 vascular deaths). After adjustment for other risk factors, AAP of any size were not associated with an increased risk of combined vascular events (HR 1.07, 95% CI 0.44 to 2.56). The same result was observed for large AAP (HR 0.94, CI 0.34 to 2.64). Age (HR 1.05, CI 1.01 to 1.10), body mass index (HR 1.08, CI 1.01 to 1.15) and atrial fibrillation (HR 3.52, CI 1.07 to 11.61) showed independent association with vascular events. In a sub-analysis with ischemic stroke as outcome, neither AAP of any size nor large AAP were associated with an increased risk. CONCLUSIONS: In this cohort without prior stroke, the incidental detection of AAP was not associated with an increased risk of future vascular events. Associated co-factors may affect the AAP-related risk of vascular events reported in previous studies.

Backgrounds: Previous studies reported inconsistent results regarding associations between apolipoprotein E (APOE) polymorphism and clinical outcomes after ischemic stroke (IS), intracerebral hemorrhage (ICH), or subarachnoid hemorrhage (SAH). Thus, the study was designed to make a systematic review and meta-analysis regarding the association between APOE polymorphism and clinical outcome after IS, ICH, and SAH. Methods: To identify studies eligible for this meta-analysis, we searched for articles published before August 2021 in the databases (PubMed, Web of Science, and Google Scholar). We used STATA 12.0 software to compute hazard ratios (HRs) and their 95% confidence intervals (CIs) regarding APOE polymorphism and clinical outcome after IS, ICH, and SAH. Results: Meta-analysis showed no significant association between APOE polymorphism and functional outcome after IS with fixed effects models (ε4 carrier vs. non-ε4 carrier: HR, 1.00; 95% CI: 0.83–1.21, I2 = 29.4%, p = 0.183; ε2 carrier vs. non-ε2 carrier: HR, 0.92; 95% CI: 0.72–1.16, I2 = 15.6%, p = 0.307). Meta-analysis showed that ICH patients carrying ε4 allele have increased risk of poor outcome in Caucasian population with fixed effects models (ε4 carrier vs. non-ε4 carrier: HR, 1.75; 95% CI: 1.19–2.57, I2 = 0.0%, p = 0.543). Meta-analysis showed no significant association between APOE polymorphism and functional outcomes after SAH with random effects models (ε4 carrier vs. non-ε4 carrier: HR, 1.51; 95% CI: 0.80–2.84, I2 = 57.1%, p = 0.022). Conclusions: In conclusion, the present study demonstrated APOE ε4 carriers show worse functional outcomes after ICH, but not after IS or SAH. More large-scale studies were critical to explore the association between APOE polymorphism and clinical outcome after IS, ICH, and SAH.

Background Aneurysm of proximal thoracic aorta (pTAA) is an often indolent, yet fatal disease. Although advancements in aneurysmal repair techniques have increased long-term survival rates, studies have proven that there are increases in perioperative risk for stroke incidence after pTAA surgery. Conversely, there is little evidence regarding the long-term stroke incidence in pTAA individuals, which strongly influences the morbidity, mortality, and usage of antithrombotic agents. Methods Using the Taiwan National Health Insurance Research Database, a nationwide population-based cohort, we recruited 3013 pTAA survivors hospitalized from 1 January 2000 to 31 December 2012. To ensure study cohort quality, only patients aged 20 years and above who underwent aneurysmal repair surgery are included. The control cohort is identified by matching background features (comorbidities, age, gender) at a 1:4 ratio through the use of frequency matching. The primary outcomes include incidence of ischemic stroke and intracranial hemorrhage one month after aneurysmal repair surgery. Results The mortality of pTAA survivors is nearly twice of the matched controls despite aneurysmal repair (28.5 % vs. 15.2%, p < 0.001). Long-term follow-up of participants indicated that pTAA survivors had a higher risk for hemorrhage stroke (adjusted hazard ratio (aHR): 1.93; 95% confidence interval (CI): 1.47–2.53), but no significant increase in risk for ischemic stroke (aHR: 1.07; 95% CI: 0.92–1.25). Hemorrhagic stroke occurrence was found to be associated with age and diabetes mellitus. Comparison on hemorrhagic stroke subtypes between study and matched cohorts showed no statistical differences in intracerebral hemorrhage and subarachnoid hemorrhage. Conclusions Despite the advancement of aneurysmal repair surgery, this study suggests that pTAA patients may still face an increased risk of hemorrhage stroke. Further investigation is warranted to provide better long-term care for the pTAA population.
