Background:The postoperative changes in the coagulation-fibrinolysis system and the association between the system and postoperative course of patients with chronic thromboembolic pulmonary hypertension (CTEPH) who have undergone pulmonary endarterectomy (PEA) remain unclear.Methods and Results:Between 1986 and 2013, 117 patients (55.1±11.2 years, preoperative mean pulmonary arterial pressure 46.5±10.5 mmHg) underwent PEA, and 15 patients died during the perioperative period. We studied the association between the preoperative coagulation-fibrinolysis markers and surgical outcomes of all patients, and the long-term outcomes of the 102 survivors from the date of PEA. We also investigated the postoperative changes in coagulation-fibrinolysis markers and their association with residual pulmonary hypertension (PH) in 20 consecutive patients. Only an elevated factor VIII level was associated with perioperative death. Thrombomodulin and plasminogen values were significantly increased after PEA. Univariate logistic regression analysis revealed that D-dimer positivity at follow-up was a risk factor for residual PH. Patients with both an elevated fibrinogen level (≥291 mg/dl [median]) and decreased plasminogen activity (<100% [median]) had significantly worse disease-specific survival than the other patients (5-year disease-specific survival: 84.0% vs. 100%, respectively; P=0.0041 [log-rank test]).Conclusions:Preoperatively high fibrinogen and low plasminogen values in patients with CTEPH are associated with poor long-term postoperative outcome. PEA benefited not only the pulmonary hemodynamics but also the coagulation-fibrinolysis system of patients.

Background:Trends of oral anticoagulant (OAC) prescription and incidence of thromboembolism (TE) and/or major bleeding (MB) in patients with non-valvular atrial fibrillation (NVAF) in Japan are still unclear.Methods and Results:We used data from Shinken Database 2004–2012, which included all new patients attending the Cardiovascular Institute between June 2004 and March 2013. Of them, 2,434 patients were diagnosed with NVAF. Patients were divided into 3 time periods according to the year of initial visit: 2004–2006 (n=681), 2007–2009 (n=833), and 2010–2012 (n=920). OAC prescription rate steadily increased from 2004–2006 to 2010–2012. Between 2004–2006 and 2007–2009, irrespective of increased warfarin usage, MB tended to decrease, presumably due to low-intensity therapy and avoidance of concomitant use of dual antiplatelets, but TE did not improve. In 2010–2012, direct OACs (DOAC), preferred in low-risk patients, may have contributed to not only decrease TE, but also increase MB, especially extracranial bleeds. In high-risk patients in that time period, mostly treated with warfarin, incidence of TE and MB did not improve.Conclusions:The 9-year trend of stroke prevention indicated a steady increase of OAC prescription and a partial improvement of TE and MB. Even in the era of DOAC, TE prevention was insufficient in high-risk patients, and DOAC were associated with increased extracranial bleeding.

Background: A prospective, 3-year comparative observational study compared the risk of cardiovascular events in patients with osteoarthritis or rheumatoid arthritis prescribed celecoxib or a nonsteroidal antiinflammatory drug (NSAID). Methods and Results: Patients prescribed celecoxib (n=5,470) or NSAIDs (n=5,059) between November 1, 2007, and July 31, 2008 in 1,084 hospitals and clinics in Japan were eligible for safety analysis. Mean (standard deviation) observation for the celecoxib group was 716 (420) days and 692 (426) days for the NSAID group (P=0.004). Composite I (adjudicated cardiovascular adverse events of myocardial infarction, angina pectoris, heart failure, cerebral infarction, cerebral hemorrhage) number of events (percentage) and rate/1,000 person years was 66 (1.2%) and 6.2 (10,745 person years), respectively, for the celecoxib and 65 (1.3%) and 6.8 (9,601 person years) for the NSAID (P=0.58) groups. Composite II (all cardiovascular events) number of events (percentage) and rate/1,000 person years was 79 (1.4%) and 7.4, respectively, for the celecoxib and 84 (1.7%) and 8.8 for the NSAID (P=0.26) group. Adjusted Cox hazards ratio (95% confidence interval) was 0.89 (0.63–1.27; P=0.52) for Composite I, 0.87 (0.63–1.19; P=0.39) for Composite II and 1.03 (0.75–1.41; P=0.87) for death from all causes. Conclusions: After adjustment for confounding variables, celecoxib was not associated with an increase of cardiovascular risk in comparison with nonselective NSAID in Japanese patients with rheumatoid arthritis or osteoarthritis in an observational setting.

Background: Hyperpolypharmacy is associated with adverse outcomes in older adults, but because literature on its association with cardiovascular (CV) outcomes after acute decompensated heart failure (ADHF) is sparse, we investigated the relationships among hyperpolypharmacy, medication class, and death in patients with HF.Methods and Results: We evaluated the total number of medications prescribed to 884 patients at discharge following ADHF. Patients were categorized into nonpolypharmacy (<5 medications), polypharmacy (5–9 medications), and hyperpolypharmacy (≥10 medications) groups. We examined the relationship of polypharmacy status with the 2-year mortality rate. The proportion of patients taking ≥5 medications was 91.3% (polypharmacy, 55.3%; hyperpolypharmacy, 36.0%). Patients in the hyperpolypharmacy group showed worse outcomes than patients in the other 2 groups (P=0.002). After multivariable adjustment, the total number of medications was significantly associated with an increased risk of death (hazard ratio [HR] per additional increase in the number of medications, 1.05; 95% confidence interval [CI], 1.01–1.10; P=0.027). Although the number of non-CV medications was significantly associated with death (HR, 1.07; 95% CI, 1.02–1.13; P=0.01), the number of CV medications was not (HR, 1.01; 95% CI, 0.92–1.10; P=0.95).Conclusions: Hyperpolypharmacy due to non-CV medications was associated with an elevated risk of death in patients after ADHF, suggesting the importance of a regular review of the prescribed drugs including non-CV medications.

Background: Acute decompensated heart failure (ADHF) has a poor prognosis and common comorbidities may be contributory. However, evidence for the association between dementia and clinical outcomes in patients with is sparse and it requires further investigation into risk reduction.Methods and Results: We assessed the clinical profiles and outcomes of 1,026 patients (mean age 77.8 years, 43.2% female) with ADHF enrolled in the CURE-HF registry to evaluate the relationship between investigator-reported dementia status and clinical outcomes (all-cause death, cardiovascular (CV) death, non-CV death, and HF hospitalization) over a median follow-up of 2.7 years. In total, dementia was present in 118 (11.5%) patients, who experienced more drug interruptions and HF admissions due to infection than those without dementia (23.8% vs. 13.1%, P<0.01; 11.0% vs. 6.0%, P<0.01, respectively). Kaplan-Meier analysis revealed that dementia patients had higher mortality rates than those without dementia (log-rank P<0.001). After multivariable adjustment for demographics and comorbidities, dementia was significantly associated with an increased risk of death (adjusted hazard ratio, 1.43; 95% confidence interval, 1.06–1.93, P=0.02) and non-CV death (adjusted hazard ratio, 1.65; 95% confidence interval, 1.04–2.62, P=0.03), but no significant associations between dementia and CV death or HF hospitalization were observed (both, P>0.1).Conclusions: In ADHF patients dementia was associated with aggravating factors for HF admission and elevated risk of death, primarily non-CV death.

Background: Heart failure with preserved ejection fraction (HFpEF) is an increasing health problem associated with high morbidity and mortality rates. Several reports have shown an association between hypokalemia and clinical outcomes in patients with heart failure (HF). However, the association of hypokalemia with kidney function and clinical outcomes in patients with HFpEF remains unclear.Methods and Results: We measured serum potassium levels and kidney function in 454 patients with HFpEF (mean age 76 years; 55% men) at admission. Hypokalemia (K+<3.5 mmol/L) and hyperkalemia (K+>5.0 mmol/L) were identified in 58 (12.7%) and 11 (2.4%) patients, respectively. Patients with hypokalemia showed renal tubular damage (RTD), defined as a urinary β2-microglobulin to creatinine ratio ≥300 μg/gCr, preserved estimated glomerular filtration rate (eGFR), and plasma volume expansion. Multivariate logistic analysis demonstrated that RTD, preserved eGFR, and plasma volume expansion were significantly associated with hypokalemia. During the median follow-up period of 1,000 days, 82 HF-related events occurred. Kaplan-Meier analysis showed that patients with hypokalemia had a higher rate of HF-related events than those without hypokalemia. Multivariate Cox proportional hazard regression analysis demonstrated that hypokalemia was significantly associated with HF-related events after adjusting for confounding factors.Conclusions: Hypokalemia is affected by kidney function, notably RTD, in patients with HFpEF. Hypokalemia is a risk factor for HF-related events in patients with HFpEF.

Background: Enhanced discussions regarding end-of-life (EOL) are crucial to provide appropriate care for seriously ill patients. However, the current status of EOL discussions, especially their timing and influencing factors, among patients with cardiovascular diseases (CVD) remains unknown.Methods and Results: We conducted a cross-sectional questionnaire survey of bereaved family members of CVD patients who died at 10 tertiary care institutes in Japan. In all, 286 bereaved family members (38.2% male; median age 66.0 [interquartile range 58.0–73.0] years) of CVD patients were enrolled; of these, 200 (69.9%) reported that their families had had EOL discussions with physicians. The major topic discussed was resuscitation (79.0%), and 21.5% discussed the place of EOL care. Most discussions were held during hospitalization of the patient (88.2%). More than half (57.1%) the discussions were initiated less than 1 month before the patient died, and 22.6% of family members felt that this timing of EOL discussions was late. Bereaved family members’ perception of late EOL discussions was associated with the family members aggressive attitude towards life-prolonging treatment, less preparedness for bereavement, and less satisfaction with EOL care.Conclusions: Approximately 70% of bereaved family members of CVD patients had EOL discussions, which were often held shortly before the patient died. Further research is required to establish an ideal approach to EOL discussions at an appropriate time, which may improve the quality of EOL care.

Background: Left heart abnormalities are risk factors for heart failure. However, echocardiography is not always available. Electrocardiograms (ECGs), which are now available from wearable devices, have the potential to detect these abnormalities. Nevertheless, whether a model can detect left heart abnormalities from single Lead I ECG data remains unclear.Methods and Results: We developed Lead I ECG models to detect low ejection fraction (EF), wall motion abnormality, left ventricular hypertrophy (LVH), left ventricular dilatation, and left atrial dilatation. We used a dataset comprising 229,439 paired sets of ECG and echocardiography data from 8 facilities, and validated the model using external verification with data from 2 facilities. The area under the receiver operating characteristic curves of our model was 0.913 for low EF, 0.832 for wall motion abnormality, 0.797 for LVH, 0.838 for left ventricular dilatation, and 0.802 for left atrial dilatation. In interpretation tests with 12 cardiologists, the accuracy of the model was 78.3% for low EF and 68.3% for LVH. Compared with cardiologists who read the 12-lead ECGs, the model’s performance was superior for LVH and similar for low EF.Conclusions: From a multicenter study dataset, we developed models to predict left heart abnormalities using Lead I on the ECG. The Lead I ECG models show superior or equivalent performance to cardiologists using 12-lead ECGs.

Background: Takayasu arteritis, affecting primarily young women, damages large arteries and organs. We examined the impact of disease duration and sex on organ damage and quality of life using Japan’s Intractable Disease Registry.Methods and Results: After refining data, 2,013 of 2,795 patients were included in the study. Longer disease duration was related to a lower prevalence of disease activity symptoms, a higher prevalence of organ damage, and a higher proportion of patients requiring nursing care. Compared with men, women tended to have an earlier onset age, exhibiting longer disease duration. A higher proportion of women had aortic regurgitation and required nursing care. The proportion of female patients in employment was lower than that of the general female population, whereas no difference was observed between male patients and the general male population. Logistic regression analysis revealed that age at surveillance, brain ischemia, visual impairment/loss, and ischemic heart disease were significant factors associated with high nursing care needs (Level ≥2, with daily activity limitations).Conclusions: Early diagnosis and effective treatment, particularly to prevent brain ischemia, visual impairment, and ischemic heart disease, may improve the quality of life of patients with Takayasu arteritis, especially women.

Takayasu arteritis (TAK) is a rare disease characterized by inflammation of large blood vessels, which results in vascular stenosis, occlusion, and aneurysm formation. The principal treatment has been glucocorticoids, but the recent emergence of biological disease-modifying anti-rheumatic drugs (bDMARDs), represented by tocilizumab (TCZ), has significantly changed the treatment landscape. Both cardiologists and cardiovascular surgeons will encounter patients receiving these drugs who require catheterization, other invasive procedures, or surgery. Several bDMARDs have shown promise against TAK in clinical studies and their use is expected to increase in the future. Janus kinase inhibitors may also be effective. Here, we review the evidence supporting the use of TCZ and other immunosuppressants in TAK and provides an update on their status as well as the relevant guidelines.

Background: In 2016, the DANISH study reported negative results regarding the efficacy of implantable cardioverter-defibrillators (ICDs) in patients with non-ischemic cardiomyopathy (NICM) and reduced left ventricular ejection fraction (LVEF). In this study we determined the efficacy of using ICDs for primary prophylaxis in patients with NICM.Methods and Results: We selected 1,274 patients with underlying cardiac disease who were enrolled in the Nippon Storm Study. We analyzed the data of 451 patients with LVEF ≤35% due to NICM or ischemic cardiomyopathy (ICM) who underwent ICD implantation for primary prophylaxis (men, 78%; age, 65±12 years; LVEF, 25±6.4%; cardiac resynchronization therapy, 73%; ICM, 33%). After propensity score matching, we compared the baseline covariates between groups: NICM (132 patients) and ICM (132 patients). The 2-year appropriate ICD therapy risks were 27.7% and 12.2% in the NICM and ICM groups, respectively (hazard ratio, 0.390 [95% confidence interval, 0.218–0.701]; P=0.002).Conclusions: This subanalysis of propensity score-matched patients from the Nippon Storm Study revealed that the risk of appropriate ICD therapy was significantly higher in patients with NICM than in those with ICM.

Background: Atrial tachyarrhythmias (ATAs) are reportedly associated with ventricular arrhythmias (VAs). However, little is known about the association between ATA duration and the risk of VA. We investigated the relationship between ATA duration and subsequent VA in patients with a cardiac resynchronization therapy defibrillator (CRT-D).Methods and Results: We investigated associations between the longest ATA duration during the first year after cardiac resynchronization therapy (CRT) implantation and VA and VA relevant to ATA (VAATA) in 160 CRT-D patients. ATAs occurred in 63 patients in the first year. During a median follow-up of 925 days from 1 year after CRT implantation, 40 patients experienced 483 VAs. Kaplan-Meier analysis showed a significantly higher risk of VA in patients with than without ATA in the first year (log rank P=0.0057). Hazard ratios (HR) of VA (HR 2.36, 2.10, and 3.04 for ATA >30s, >6 min and >24 h, respectively) and only VAATA (HR 4.50, 5.59, and 11.79 for ATA >30s, >6 min and >24 h, respectively) increased according to the duration of ATA. In multivariate analysis, ATA >24 h was an independent predictor of subsequent VA (HR 2.42; P=0.02).Conclusions: Patients with ATA >24 h in the first year after CRT had a higher risk of subsequent VA and VAATA. The risk of VA, including VAATA, increased with the longest ATA duration.

Despite advancements in treatments for heart failure and lethal arrhythmias, achieving satisfactory life prognoses remains a challenge. A fresh perspective on the pathogenesis of heart disease is imperative to improve these prognoses. Our research has highlighted the role of cardiac macrophages in inhibiting the onset of heart failure and sudden cardiac death. We have recently unveiled a collaborative mechanism involving immune cells, brain neural networks, and the kidneys, which work in concert to combat cardiovascular diseases. This intricate organ network, orchestrated by the brain neural network and immune system, is pivotal in maintaining whole-body homeostasis. Disruptions in this harmonious interplay can precipitate various conditions, including heart failure and multiple organ failure, underscoring the significance of technological advancements in analytical methods and the advent of artificial intelligence. Recent strides in circulatory organ research have facilitated concurrent high-level analysis of the neural network and cardiovascular system. This review encapsulates these cutting-edge reports, evaluates the progress of research anchored in the fundamental concept that system failure of the cardiovascular organ precipitates cardiovascular disease, and offers valuable insights to guide future research.
