Abstract
Cardiovascular diseases (CVDs), such as heart disease and stroke, have a significant impact on life expectancy, healthy life expectancy, and medical costs in Japan. Each prefecture is currently promoting measures in accordance with the Japanese National Plan for Promotion of Measures Against Cerebrovascular and Cardiovascular Disease, which was established by the government. In recent years, the crude mortality rate of heart disease in Japan has been increasing year by year with the aging population. Meanwhile, the age-adjusted mortality rate has leveled off or shown a downward trend. In addition, the proportion of acute myocardial infarction has decreased, whereas the proportion of heart failure has increased. By contrast, both the crude and age-adjusted mortality rates of stroke have a declining trend. Nevertheless, considering the potential variations in death certificates issued for patients with myocardial infarction across different prefectures, it is crucial to determine the incidence of CVD in each prefecture for the accurate assessment of CVD trends. However, as for the incidence of CVD, not many prefectures have yet implemented registration programs. The age-adjusted incidence rate of acute myocardial infarction has been increasing in some areas and decreasing in others since 1990. The age-adjusted incidence rate of stroke has consistently declined since the 1960s. Nevertheless, the possible increase in the incidence rate of cerebral embolism and thrombotic cerebral infarction among patients with different stroke subtypes is a cause of concern. The impact of heart failure on the incidence of heart disease has increased. Therefore, relevant academic societies and prefectures must collaborate in registering the incidence of heart failure as well as myocardial infarction and implementing countermeasures.

Prevalence of intracranial hemorrhage amongst patients presenting with out-of-hospital cardiac arrest: A systematic review and meta-analysis. Resuscitation 2022; 176:136-149. [PMID: 35551955 DOI: 10.1016/j.resuscitation.2022.05.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 04/13/2022] [Accepted: 05/01/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION An unknown proportion of out-of-hospital cardiac arrest (OHCA) is caused by intracranial hemorrhage (ICH). There is uncertainty over the role of early head computed tomography (CT) in non-traumatic OHCA due to uncertain diagnostic yield and ways to identify high-risk patients. This study aimed to identify the prevalence of ICH in non-traumatic OHCA and possible predictors. METHODS PubMed, EMBASE, and the Cochrane library were searched from inception to January 2022. Data extraction and quality assessment were independently reviewed by two authors. Meta-analyses estimated the prevalence of ICH amongst OHCA patients and pre-specified subgroups and geographical settings. Subgroup analysis were used to explore potential clinical predictors. RESULTS 23 studies involving 54,349 patients were included. The pooled ICH prevalence was 4.28% (95%CI: 3.31-5.24). Asia had a significantly larger risk ratio (RR= 3.93, P value < 0.0001) than Europe. The ICH subgroup was significantly more likely to be female (OR: 2.16; 95%CI: 1.10-4.26), and less likely to experience shockable rhythms compared with non-shockable rhythms (OR: 0.22; 95% CI: 0.04-1.22), achieve ROSC prior to arrival (OR: 0.27; 95%CI: 0.10-0.77), and survive to discharge compared to those without ICH (OR: 0.26; 95%CI: 0.11-0.59). CONCLUSIONS One in twenty OHCA have ICH at the time of presentation. An early head CT scan should be strongly considered after return of spontaneous circulation (ROSC), especially in patients who are female, with non-shockable rhythm and did not attain ROSC prior to arrival. These finding should influence clinical protocols to favor routine scans especially in Asia where prevalence is higher.

Abstract
Intracerebral hemorrhage (ICH) is a devastating form of stroke with high morbidity and mortality. This review article focuses on the epidemiology, cause, mechanisms of injury, current treatment strategies, and future research directions of ICH. Incidence of hemorrhagic stroke has increased worldwide over the past 40 years, with shifts in the cause over time as hypertension management has improved and anticoagulant use has increased. Preclinical and clinical trials have elucidated the underlying ICH cause and mechanisms of injury from ICH including the complex interaction between edema, inflammation, iron-induced injury, and oxidative stress. Several trials have investigated optimal medical and surgical management of ICH without clear improvement in survival and functional outcomes. Ongoing research into novel approaches for ICH management provide hope for reducing the devastating effect of this disease in the future. Areas of promise in ICH therapy include prognostic biomarkers and primary prevention based on disease pathobiology, ultra-early hemostatic therapy, minimally invasive surgery, and perihematomal protection against inflammatory brain injury.

Abstract
Background and Purpose Recent epidemiological data indicate that the absolute number of hemorrhagic stroke cases increased by 47% between 1990 and 2010 and continued to cause high rates of death and disability. The last systematic review and meta-analysis of incidence and long-term survival of intracerebral hemorrhage (ICH) were published 11 and 7 years ago, respectively, and lacked comparison between different income groups, therefore, a more up to date analysis is needed. We aim to investigate the ICH incidence and long-term survival data in countries of different income groups. Materials Methods We systematically searched Ovid Medline for population-based longitudinal studies of first-ever spontaneous ICH published from January 2000 to December 2020. We performed meta-analyses on the incidence and survival rate in countries of 4 different income groups with random-effects models (severe inconsistency). The I2 was used to measure the heterogeneity. Heterogeneity was further investigated by conducting the meta-regression on the study mid-year. Time trends of the survival rate were assessed by weighted linear regression. Results We identified 84 eligible papers, including 68 publications reporting incidence and 24 publications on the survival rate. The pooled incidence of ICH per 100,000 per person-years was 26.47 (95% CI: 21.84–32.07) worldwide, 25.9 (95% CI: 22.63–29.63) in high-income countries (HIC), 28.45 (95% CI: 15.90–50.88) in upper-middle-income countries, and 31.73 (95% CI: 18.41–54.7) in lower-middle-income countries. The 1-year pooled survival rate was from 50% (95% CI: 47–54%; n = 4,380) worldwide to 50% (95% CI: 47–54%) in HIC, and 46% (95% CI: 38–55%) in upper-middle income countries. The 5-year pooled survival rate was 41% (95% CI: 35–48%; n = 864) worldwide, 41% (95% CI: 32–50%) in high-income and upper-middle countries. No publications were found reporting the long-term survival in lower-middle-income and low-income countries. No time trends in incidence or survival were found by meta-regression. Conclusion The pooled ICH incidence was highest in lower-middle-income countries. About half of ICH patients survived 1 year, and about two-fifths survived 5 years. Reliable population-based studies estimating the ICH incidence and long-term survival in low-income and low-middle-income countries are needed to help prevention of ICH.

Mutational and clinical spectrum of Japanese patients with hereditary hemorrhagic telangiectasia. BMC Med Genomics 2021; 14:288. [PMID: 34872578 PMCID: PMC8647423 DOI: 10.1186/s12920-021-01139-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 11/29/2021] [Indexed: 12/28/2022] Open
Abstract
Background Hereditary hemorrhagic telangiectasia (HHT) is a dominantly inherited vascular disorder characterized by recurrent epistaxis, skin/mucocutaneous telangiectasia, and organ/visceral arteriovenous malformations (AVM). HHT is mostly caused by mutations either in the ENG or ACVRL1 genes, and there are regional differences in the breakdown of causative genes. The clinical presentation is also variable between populations suggesting the influence of environmental or genetic backgrounds. In this study, we report the largest series of mutational and clinical analyses for East Asians. Methods Using DNAs derived from peripheral blood leukocytes of 281 Japanese HHT patients from 150 families, all exons and exon–intron boundaries of the ENG, ACVRL1, and SMAD4 genes were sequenced either by Sanger sequencing or by the next-generation sequencing. Deletions/amplifications were analyzed by the multiplex ligation-dependent probe amplification analyses. Clinical information was obtained by chart review. Results In total, 80 and 59 pathogenic/likely pathogenic variants were identified in the ENG and ACVRL1 genes, respectively. No pathogenic variants were identified in the SMAD4 gene. In the ENG gene, the majority (60/80) of the pathogenic variants were private mutations unique to a single family, and the variants were widely distributed without any distinct hot spots. In the ACVRL1 gene, the variants were more commonly found in exons 5–10 which encompasses the serine/threonine kinase domain. Of these, 25/59 variants were unique to a single family while those in exons 8–10 tended to be shared by multiple (2–7) families. Pulmonary and cerebral AVMs were more commonly found in ENG-HHT (69.1 vs. 14.4%, 34.0 vs. 5.2%) while hepatic AVM was more common in ACVRL1-HHT (31.5 vs. 73.2%). Notable differences include an increased incidence of cerebral (34.0% in ENG-HHT and 5.2% in ACVRL1-HHT), spinal (2.5% in ENG-HHT and 1.0% in ACVL1-HHT), and gastric AVM (13.0% in ENG-HHT, 26.8% in ACVRL1-HHT) in our cohort. Intrafamilial phenotypic heterogeneity not related to the age of examination was observed in 71.4% and 24.1% of ENG- and ACVRL1-HHT, respectively. Conclusions In a large Japanese cohort, ENG-HHT was 1.35 times more common than ACVRL1-HHT. The phenotypic presentations were similar to the previous reports although the cerebral, spinal, and gastric AVMs were more common.

Abstract
BACKGROUND AND AIMS Correlations between serum levels of polyunsaturated fatty acids (PUFAs) such as eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), arachidonic acid (AA) and dihomogammalinolenic acid (DHLA) and outcomes following cardiovascular disease have been reported. This study aimed to investigate the relationship between serum levels of PUFAs (including AA) and functional outcomes among intracerebral hemorrhage (ICH) patients. METHODS From November 2012 to July 2020, ICH patients within 24 h from onset were enrolled. Patients were divided into a good functional outcome group (modified Rankin Scale [mRS] score at 3 months, 0-3) and a poor functional outcome group (mRS score at 3 months, 4-6). We compared baseline variables between groups. RESULTS Participants comprised 133 patients (mean age, 60 years), with 106 patients (80%) in the good functional outcome group and 27 patients (20%) in the poor functional outcome group. Higher National Institutes of Health Stroke Scale (NIHSS) score and larger hematoma on admission were more frequent in the poor functional outcome group (median NIHSS score 6 vs. 14, p < 0.001; median hematoma volume, 7.5 ml vs. 13.5 ml, p = 0.07). In terms of serum PUFA levels, only median serum AA level was significantly lower in the poor functional outcome group (212 µg/ml vs. 179 µg/ml, p = 0.002). Multivariate logistic regression analysis showed lower serum AA level was independently associated with poor functional outcome (odds ratio 0.986, 95% confidence interval 0.976-0.996, p = 0.009). CONCLUSION Lower serum AA level was associated with poor functional outcome in ICH patients. AA may represent an important biomarker of severity among ICH patients.

Abstract
Objective It has been established that stroke occurrence is influenced by seasonality. Stroke is divided into three subtypes: cerebral hemorrhage (CH), cerebral infarction (CI), and subarachnoid hemorrhage (SAH). The purpose of this paper was to analyze stroke events by subtype and month, in order to clarify the biggest factors that affect seasonal differences and thereby gain insight into stroke prevention. Methods Initial stroke events in the Akita Stroke Registry from 1991 to 2010 (58,684 cases; male 30,549, female 28,135) were classified by subtype and the month of onset, and correlations were estimated based on 115 healthy volunteers' monthly mean resting blood pressure (BP) at home and outdoor temperature measured by the Akita Meteorological Observatory in 2001. Results Systolic BP showed monthly variation in both morning and evening measurements. BP and outdoor temperature showed significant correlations with hemorrhagic stroke events by month (CH: r=0.87, r=-0.82; SAH: r=0.68, r=-0.82). Among the stroke subtypes, seasonal differences were the greatest in CH. Systolic BP was the most important factor for monthly and seasonal variation in stroke events. By comparing monthly BP variations with CH incidence throughout the year, we concluded that a decrease in home BP of 5 mmHg can reduce the risk of CH by 35%. Conclusion Our findings suggest that lowering BP would be the best strategy for CH prevention. Simple daily actions may be affected by cold stress. As physicians, we must strive to help patients lower their BP throughout the year not only with medication but with lifestyle guidance, especially in winter.

Abstract
AIM Intracranial Hemorrhage (ICH) is an important cause of out-of-hospital cardiac arrest (OHCA), yet there are no United States (US), European, or Australian prospective studies examining its incidence in patients who sustained OHCA. This study aims to identify the incidence of ICH in US patients with OHCA who obtain return of spontaneous circulation (ROSC). METHODS We prospectively analyzed consecutive patients with OHCA who achieved ROSC at a single US hospital over a 15-month period. Before beginning patient enrollment, we implemented a standardized emergency department order-set for the initial management for all patients with ROSC after OHCA. This order-set included a non-contrast head computed-tomography (NCH-CT) scan. Patient and cardiac arrest variables were recorded, as were NCH-CT findings. RESULTS During the study period, 85 patients sustained an OHCA, achieved ROSC, survived to hospital admission, and underwent a NCH-CT. Three of these 85 patients had ICH (3.5%). Survival to discharge was seen in 23/82 (28.0%) patients without ICH and in 1/3 patients with ICH. Survival with good neurologic outcome was seen in 14/82 (17.1%) patients without ICH and in 0/3 patients with ICH. Patients with ICH tended to be older than patients without ICH. CONCLUSIONS In our US cohort, ICH was an uncommon finding in patients who sustained OHCA and survived to hospital admission, and no patients with ICH survived to discharge with good neurologic outcome. Additionally, the incidence of ICH was lower than reported in previous studies.

Abstract
Background Evidence on the associations of carotid intima-media thickness and carotid plaque characteristics with stroke subtypes and coronary artery disease risks in Asians is limited. This study investigated these associations in the Japanese general population. Methods and Results Maximum intima-media thicknesses of both the common carotid artery and internal carotid artery and carotid plaque characteristics were evaluated in 2943 Japanese subjects aged 40 to 75 years without history of cardiovascular disease. Subjects were followed up for a median of 15.1 years. Using a multivariate Cox proportional hazard model, we found that hazard ratios (HRs) and 95% CIs for the highest (≥1.07 mm) versus lowest (≤0.77 mm) quartiles of maximum intima-media thicknesses of the common carotid artery were 1.97 (1.26-3.06) for total stroke, 1.52 (0.67-3.41) for hemorrhagic stroke, 2.45 (1.41-4.27) for ischemic stroke, 3.60 (1.64-7.91) for lacunar infarction, 1.53 (0.69-3.41) for nonlacunar cerebral infarction, 2.68 (1.24-5.76) for coronary artery disease, and 2.11 (1.44-3.12) for cardiovascular disease (similar results were found for maximum intima-media thicknesses of the internal carotid artery). HRs(95% CIs) for heterogeneous plaque versus no plaque were 1.58 (1.09-2.30) for total stroke, 1.25 (0.58-2.70) for hemorrhagic stroke, 1.74 (1.13-2.67) for ischemic stroke, 1.84 (1.03-3.19) for lacunar infarction, 1.58 (0.80-3.11) for nonlacunar cerebral infarction, 2.11 (1.20-3.70) for coronary artery disease, and 1.71 (1.25-2.35) for cardiovascular disease. Conclusions Maximum intima-media thicknesses of the common carotid artery, maximum intima-media thicknesses of the internal carotid artery, and heterogeneous plaque were associated with the risks of stroke, lacunar infarction, coronary artery disease, and cardiovascular disease in Asians.

Abstract
We aimed to investigate the relationship between high-density lipoprotein cholesterol (HDL-C) concentration and the incident stroke subtypes. We enrolled 11 027 participants between the ages of 18 and 90 years without a history of stroke in 12 Japanese communities. Cox's regression models were used for stroke subtypes, adjusted for traditional risk factors, according to the categories based on HDL-C concentrations: 1.04 to 1.55 mmol/L, ≥1.56 mmol/L, and <1.03 mmol/L (as the reference). During a mean follow-up of 10.7 years, 412 stroke events had occurred. However, HDL-C was not significantly associated with the incidence of cerebral infarction and subarachnoid hemorrhage. High HDL-C concentration was associated with a decreased incidence of intracerebral hemorrhage in women (hazard ratio = 0.23; 95% confidence interval = 0.06-0.89), but not in men (hazard ratio = 0.73; 95% confidence interval = 0.27-1.97). Therefore, high HDL-C concentration might have a protective effect on the incidence of intracerebral hemorrhage, particularly in women.

Abstract
Blood clotting is a fundamental biochemical process in post-hemorrhagic hemostasis. Although the varying appearance of coagulating blood in T1 - and T2 -weighted images is widely used to qualitatively determine bleeding age, the technique permits only a rough discrimination of coagulation stages, and it remains difficult to distinguish acute and chronic hemorrhagic stages because of low T1 - and T2 -weighted signal intensities in both instances. To investigate new biomedical parameters for magnetic resonance imaging-based characterization of blood clotting kinetics, sodium imaging and quantitative susceptibility mapping (QSM) were compared with conventional T1 - and T2 -weighted imaging, as well as with biochemical hemolysis parameters. For this purpose, a blood-filled spherical agar phantom was investigated daily for 14 days, as well as after 24 days at 7 T after initial preparation with fresh blood. T1 - and T2 -weighted sequences, a three-dimensional (3D) gradient echo sequence and a density-adapted 3D radial projection reconstruction pulse sequence for 23 Na imaging were applied. For hemolysis estimations, free hemoglobin and free potassium concentrations were measured photometrically and with the direct ion-selective electrode method, respectively, in separate heparinized whole-blood samples along the same timeline. Initial mean susceptibility was low (0.154 ± 0.020 ppm) and increased steadily during the course of coagulation to reach up to 0.570 ± 0.165 ppm. The highest total sodium (NaT) values (1.02 ± 0.06 arbitrary units) in the clot were observed initially, dropped to 0.69 ± 0.13 arbitrary units after one day and increased again to initial values. Compartmentalized sodium (NaS) showed a similar signal evolution, and the NaS/NaT ratio steadily increased over clot evolution. QSM depicts clot evolution in vitro as a process associated with hemoglobin accumulation and transformation, and enables the differentiation of the acute and chronic coagulation stages. Sodium imaging visualizes clotting independent of susceptibility and seems to correspond to clot integrity. A combination of QSM and sodium imaging may enhance the characterization of hemorrhage.

Abstract
Eating patterns are increasingly varied. Typical breakfast, lunch, and dinner meals are difficult to distinguish because skipping meals and snacking have become more prevalent. Such eating styles can have various effects on cardiometabolic health markers, namely obesity, lipid profile, insulin resistance, and blood pressure. In this statement, we review the cardiometabolic health effects of specific eating patterns: skipping breakfast, intermittent fasting, meal frequency (number of daily eating occasions), and timing of eating occasions. Furthermore, we propose definitions for meals, snacks, and eating occasions for use in research. Finally, data suggest that irregular eating patterns appear less favorable for achieving a healthy cardiometabolic profile. Intentional eating with mindful attention to the timing and frequency of eating occasions could lead to healthier lifestyle and cardiometabolic risk factor management.

Abstract
BACKGROUND AND PURPOSE The incidence and cause of strokes associated with pregnancy and the puerperium are still not fully understood. The aim of this study was to characterize pregnancy-related strokes in Japan using a large-scale survey with current imaging techniques. METHODS A retrospective analysis was conducted based on clinical chart reviews in 736 stroke teaching hospitals certified by the Japan Stroke Society between 2012 and 2013, using a web-based questionnaire requesting the detailed clinical course without any personally identifying information. The collection rate of this questionnaire was 70.5%, with 151 pregnancy-associated strokes extracted. RESULTS Hemorrhagic strokes were observed in 111 cases (73.5%), ischemic strokes in 37 (24.5%), and mixed type in 3 cases (2.0%). The estimated incidence of pregnancy-associated stroke was 10.2 per 100 000 deliveries. Major causes of hemorrhage were aneurysm (19.8%), arteriovenous malformation (17.1%), pregnancy-induced hypertension (11.7%), and HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count) (8.1%). Preexisting cerebrovascular diseases responsible for hemorrhage were detected in 59 cases (53.1%). Among the ischemic strokes, 28 (75.7%) were arterial and 9 (24.3%) were venous infarctions. The most frequent cause of arterial infarctions was reversible cerebral vasoconstriction syndrome. Hemorrhagic stroke showed much poorer prognosis than ischemic stroke. CONCLUSIONS The incidence of pregnancy-associated stroke in Japan did not seem higher than that in other Asian and Western countries. The proportion of hemorrhagic stroke among Japanese women was much higher than that in white women. Preexisting cerebrovascular diseases and reversible cerebral vasoconstriction syndrome play a key role in hemorrhagic and ischemic stroke, respectively.

Abstract
BACKGROUND AND PURPOSE The association between breakfast intake and the risk of cardiovascular disease, including stroke, among Asian people remains unknown. We sought to prospectively investigate whether the omission of breakfast is related to increased risks of stroke and coronary heart disease in general Japanese populations. METHODS A total of 82,772 participants (38,676 men and 44,096 women) aged 45 to 74 years without histories of cardiovascular disease or cancer were followed up from 1995 to 2010. Participants were classified as having breakfast 0 to 2, 3 to 4, 5 to 6, or 7 times/wk. The hazard ratios of cardiovascular disease were estimated using Cox proportional hazards models. RESULTS During the 1 050 030 person-years of follow-up, we documented a total of 4642 incident cases, 3772 strokes (1051 cerebral hemorrhages, 417 subarachnoid hemorrhages, and 2286 cerebral infarctions), and 870 coronary heart disease. Multivariable analysis showed that those consuming no breakfast per week compared with those consuming breakfast everyday had hazard ratios (95% confidence interval; P for trend) of 1.14 (1.01-1.27; 0.013) for total cardiovascular disease, 1.18 (1.04-1.34; 0.007) for total stroke, and 1.36 (1.10-1.70; 0.004) for cerebral hemorrhage. Similar results were observed even after exclusion of early cardiovascular events. No significant association between the frequency of breakfast intake and the risk of coronary heart disease was observed. CONCLUSIONS The frequency of breakfast intake was inversely associated with the risk of stroke, especially cerebral hemorrhage in Japanese, suggesting that eating breakfast everyday may be beneficial for the prevention of stroke.
