Kawasaki disease (KD) induces coronary arteritis, which causes subsequent coronary aneurysms, and contributes to acute myocardial infarction (AMI). However, the differences regarding real-world treatment selection and mortality between AMI-complicated KD and AMI due to typical atherosclerosis (AMI-non KD) are unknown.The aim of the present study was to examine the current treatment strategy and prognosis of AMI-complicated KD compared with AMI due to typical atherosclerosis.We used data from 2012 to 2019 from a nationwide claim database, the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination.Compared to the AMI-non KD patients (n = 70,227), the AMI-complicated KD patients (n = 73): (1) underwent percutaneous coronary intervention (PCI) less often and more coronary artery bypass grafting, intracoronary thrombolysis or intravenous coronary thrombolysis more often; (2) underwent stentless PCI using old balloon angioplasty or rotablator, when they underwent PCI; and (3) needed in-hospital cardiopulmonary resuscitation and intensive mechanical therapy such as intra-aortic balloon pump, percutaneous cardiopulmonary support or a respirator. Both the AMI-non KD and AMI-complicated KD patients had similar in-hospital mortality rates.Compared with AMI-non KD patients, AMI-complicated KD patients underwent non-PCI strategies such as bypass surgery or thrombolysis, and required intensive therapy with mechanical supports more often, but presented similar in-hospital mortality. When the AMI-complicated KD patients underwent PCI, stentless PCI using balloon angioplasty or rotablator was performed more often compared with the AMI-non KD patients.

After the publication of the Japanese Circulation Society guideline of sleep-disordered breathing (SDB) in 2010, with new evidence and changes to the health insurance system, trends in the practice pattern for SDB in patients with cardiovascular disease (CVD) might have changed.Methods and Results: This study evaluated the temporal changes in the practice pattern for SDB by using a nationwide claim database, the Japanese Registry of All Cardiac and Vascular Diseases - Diagnosis Procedure Combination (JROAD-DPC), from 2012 to 2019. The main findings were: (1) the number of CVD patients diagnosed with SDB increased (especially those with atrial fibrillation [AF] and heart failure [HF]); (2) the number of diagnostic tests for SDB performed during hospitalization increased for AF patients (from 1.3% in 2012 to 1.8% in 2019), whereas it decreased for other CVD patients; (3) the number of patients diagnosed with SDB increased in each type of CVD, except for patients with acute myocardial infarction (AMI); (4) continuous positive airway pressure (CPAP) treatment increased for AF patients (from 15.2% to 17.5%); (5) CPAP treatment decreased for patients with angina pectoris (AP) and AMI, and any treatment decreased for HF patients (from 46.1% to 39.7%); and (6) SDB was treated more often in HF patients than in AF, AP, and AMI patients (41.7% vs. 17.2%, 19.1% and 20.4%, respectively).The practice pattern for SDB in CVD patients has changed from 2012 to 2019.

Interactions of the heart and the liver remain to be fully understood in the pathophysiology of heart failure (HF). Hepatokines are proteins synthesized and secreted from the liver and regulate systemic metabolisms of peripheral tissues. This study sought to clarify the clinical relevance of hepatokine Fetuin-A in patients with HF.We enrolled 217 participants including 187 hospitalized patients with HF and 30 control subjects who were sought with a comparable age- and sex profile and who had never had HF or structural cardiac abnormalities. First, we examined the levels of Fetuin-A and found that its levels were significantly lower in patients with HF than in the controls. Next, HF patients were categorized into four groups based on hepatic hemodynamics assessed by abdominal ultrasonography which determines liver hypoperfusion by peak systolic velocity (PSV) of the celiac artery and liver stiffness by shear wave elastography (SWE). Fetuin-A levels were significantly decreased in HF patients with liver hypoperfusion compared to those without, but were not different between HF patients with and without elevated liver stiffness. Correlation analysis revealed that circulating Fetuin-A was positively correlated with PSV of the celiac artery but not with SWE of the liver. Kaplan-Meier analysis demonstrated that HF patients with lower Fetuin-A levels were significantly associated with increased adverse outcomes including cardiac deaths and decompensated HF.Liver-derived hepatokine Fetuin-A may be a novel target involved in the cardio-hepatic interactions, as well as a useful biomarker for predicting the prognosis in patients with HF.

The Patterns of non-Adherence to Anti-Platelet Regimen in Stented Patients (PARIS) bleeding risk score has been proposed to predict the risk of bleeding events after percutaneous coronary intervention (PCI). However, the prognostic value of the PARIS bleeding risk score for long term all-cause mortality, cardiac mortality and hospitalization due to heart failure has not yet been evaluated. Therefore, the aim of the present study was to evaluate the prognostic value of the PARIS bleeding risk score for all-cause and cardiac mortalities and hospitalization due to heart failure after PCI. Consecutive 1061 patients who had undergone PCI were divided into 3 groups based on the PARIS bleeding risk score; low (n = 112), intermediate (n = 419) and high-risk groups (n = 530). We prospectively followed up the 3 groups for all-cause and cardiac mortalities and hospitalization due to heart failure. Kaplan-Meier analysis revealed that all of the outcomes were highest in the high-risk group among the 3 groups (P0.001, P0.001 and P0.001 respectively). Multivariable Cox proportional hazard analysis, adjusted for confounding factors, revealed that all-cause mortality of the intermediate or high-risk groups was higher than those of the low-risk group (adjusted hazard ratio 6.06 and 12.50, P = 0.013 and P0.001, respectively). The PARIS bleeding risk score is a significant indicator of prognosis for all-cause mortality in patients after PCI.

It is still unclear whether changes in right ventricular function are associated with prognosis in heart failure (HF) patients. This study aimed to examine the prognostic effect of changes in right ventricular fractional area change (RVFAC).Methods and Results: This study enrolled 480 hospitalized patients with decompensated HF, and measured RVFAC with echocardiography at discharge (first examination) and post-discharge in the outpatient setting (second examination). RVFAC was divided into 3 categories:35% in 314 patients, 25-35% in 108 patients, and25% in 58 patients. Next, based on changes in RVFAC from the first to the second examination, the patients were further classed into 4 groups: (1) Preserved/Unchanged (preserved and unchanged RVFAC, n=235); (2) Reduced/Improved (improved RVFAC in at least 1 category, n=106); (3) Reduced/Unchanged (reduced and unchanged RVFAC, n=47); and (4) Preserved or Reduced/Worsened (deteriorated RVAFC in at least 1 category, n=92). Multivariate logistic regression analysis revealed that chronic kidney disease and anemia were the predictors of the preserved or reduced/worsened RVFAC. In the Kaplan-Meier analysis, changes in RVFAC were associated with the cardiac event rate and all-cause mortality. In the multivariable Cox proportional hazard analysis, the preserved or reduced/worsened RVFAC was an independent predictor of cardiac events and all-cause mortality.Changes in RVFAC were associated with post-discharge prognosis in hospitalized heart failure patients.
