Tofogliflozin reduces sleep apnea severity in patients with type 2 diabetes mellitus and heart failure: a prospective study.

Sleep apnea (SA) is prevalent among patients with heart failure (HF) and contributes to a poor prognosis. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have demonstrated efficacy in reducing the risk of serious clinical events in patients with HF. Additionally, SGLT2 inhibitors may reduce the risk of incident SA and mitigate its severity in patients with cardiovascular disease and T2DM.

Correlates of sleep-disordered breathing and Cheyne-Stokes respiration in patients with atrial fibrillation who have undergone pulmonary vein isolation.

Sleep disordered breathing (SDB) is a common comorbidity in patients with atrial fibrillation (AF). Patients undergoing pulmonary vein isolation (PVI) for AF have a high prevalence of SDB. In previous studies, some patients with AF had Cheyne-Stokes respiration (CSR).

Outcome after primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction complicated by cardiogenic shock.

Background: Primary percutaneous coronary intervention (PCI) for ST-segment-elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS) may reduce the risk of subsequent cardiovascular events but remains challenging. The study aim was to evaluate the clinical characteristics and long-term outcomes of patients undergoing primary PCI for STEMI with CS.

Methods: We conducted an observational cohort study of patients with STEMI who underwent primary PCI between April 2004 and December 2017 at Juntendo University Shizuoka Hospital.

Clinical outcomes of ST elevation myocardial infarction patients without standard modifiable risk factors.

Background: Standard modifiable cardiovascular risk factors (SMuRFs; hypertension, diabetes mellitus, dyslipidemia, and smoking) are widely recognized as risk factors for coronary artery disease. However, the associations between absence of SMuRFs and long-term clinical outcomes in ST-segment elevation myocardial infarction (STEMI) patients are unclear.

Methods: Consecutive STEMI patients who underwent primary percutaneous coronary intervention (PCI) between 1999 and 2015 were retrospectively analyzed.

Diurnal Variations in Serum Uric Acid, Xanthine, and Xanthine Oxidoreductase Activity in Male Patients with Coronary Artery Disease.

Hyperuricemia is influenced by diet and can cause gout. Whether it is a potential risk factor for cardiovascular disease (CVD) remains controversial, and the mechanism is unclear. Similar to CVDs, gout attacks occur more frequently in the morning and at night.

Impact of sleep-disordered breathing on overnight changes in arterial stiffness in patients with acute heart failure.

Overnight increases in arterial stiffness associated with sleep-disordered breathing may adversely affect patients with acute heart failure. Thus, we investigated overnight changes in arterial stiffness and their association with sleep-disordered breathing in patients hospitalized for acute heart failure. Consecutive patients with acute heart failure were enrolled.

Overnight changes in uric acid, xanthine oxidoreductase and oxidative stress levels and their relationships with sleep-disordered breathing in patients with coronary artery disease.

Serum uric acid (UA) level is associated with the high cumulative incidence or prevalence of coronary artery disease (CAD), and hyperuricemia is considered as an independent risk marker for CAD. Sleep-disordered breathing (SDB) is also associated with an increased risk of CAD. Several studies have shown that SDB is associated with hyperuricemia, but the mechanisms are unclear.

Prognostic Value of Cheyne-Stokes Respiration and Nutritional Status in Acute Decompensated Heart Failure.

Malnutrition frequently coexists with heart failure (HF), leading to series of negative consequences. Cheyne-Stokes respiration (CSR) is predominantly detected in patients with HF. However, the effect of CSR and malnutrition on the long-term prognosis of patients with acute decompensated HF (ADHF) remains unclear.

Clinical features and predictors of outcome in patients with acute myocardial infarction complicated by out-of-hospital cardiac arrest.

Background: Although short-term mortality of acute myocardial infarction (AMI) has decreased dramatically in the past few decades, sudden cardiac arrest remains a serious complication. The aim of the study was to assess the clinical characteristics and predictors of prognosis in AMI patients who experienced out-of-hospital cardiac arrest (OHCA).

Methods: We retrospectively registered consecutive AMI patients who were treated with emergency percutaneous coronary intervention (PCI) between 2004 and 2017.

Impact of Lipoprotein(a) as a Residual Risk Factor in Long-Term Cardiovascular Outcomes in Patients With Acute Coronary Syndrome Treated With Statins.

The association between lipoprotein(a) (Lp[a]) levels and cardiovascular disease has been reported. However, it is still uncertain whether Lp(a) concentration could be a residual risk factor for cardiovascular events after acute coronary syndrome (ACS). The aim of the present study is to evaluate the impact of Lp(a) on long-term cardiovascular outcomes in patients with ACS treated with statins.

Prognostic effect of sleep-disordered breathing on hospitalized patients following acute heart failure.

Background: Identifying patients at risk for poor clinical outcomes following acute heart failure (AHF) is essential. However, data regarding the prognostic effect of sleep-disordered breathing (SDB) and treatment with positive airway pressure (PAP) on clinical outcomes of hospitalized patients following AHF is lacking.

Objectives: This study investigated the prognostic effect of SDB, PAP treatment, and compliance with PAP treatment on patient clinical outcomes.

A High-Echoic Layer Surrounding the Heart Suggesting Cardiac Tamponade by Clotting.

A 16-year-old boy experienced a sudden loss of consciousness. On arrival, he was in cardiac arrest. An ultrasound study revealed a high-echoic layer surrounding the heart.

Prognostic effects of arterial carbon dioxide levels in patients hospitalized into the cardiac intensive care unit for acute heart failure.

Aims: Although both hypercapnia and hypocapnia are common in acute heart failure (AHF) patients, routine assessment of arterial blood gas is not recommended. Additionally, no association between hypercapnia and increased mortality has been found, and the prognostic value of hypocapnia in AHF patients remains to be elucidated. In this observational study, we aimed to investigate the relationship between partial pressure of arterial carbon dioxide (PaCO2), especially low PaCO2, and long-term mortality in AHF patients.

Temporal changes of cardiac acoustic biomarkers and cardiac function in acute decompensated heart failure.

Aims: Relationships between cardiac acoustic biomarkers (CABs) measured by acoustic cardiography and clinical outcomes have been reported in heart failure (HF) patients. However, no studies have investigated the temporal change of CABs and the corresponding changes in HF status. The purpose of this study was to assess whether the temporal changes of CABs in patients with acute decompensated heart failure (ADHF) reflect changes in cardiac function and status.

Utility of cyclic variation of heart rate score as a screening tool for sleep-disordered breathing in patients with heart failure.

Study Objectives: Patients with sleep-disordered breathing have cyclic variation of heart rate (CVHR) in response to respiratory events. However, limited data are available regarding the utility of CVHR as a screening tool for sleep-disordered breathing in patients with mixed heart failure (HF) and those without HF.

Methods: We enrolled consecutive patients with and without HF who underwent full polysomnographies with simultaneous Holter electrocardiogram monitoring.

Impact of Prior Stroke on Long-Term Outcomes in Patients With Acute Coronary Syndrome.

Cerebrovascular disease often coexists with coronary artery disease (CAD), and it has been associated with worse clinical outcomes in CAD patients. However, the prognostic effect of prior stroke on long-term outcomes in patients with acute coronary syndrome (ACS) is still unclear. An observational cohort study of ACS patients who underwent emergency percutaneous coronary intervention (PCI) between January 1999 and May 2015 was conducted.

Clinical Characteristics and Long-Term Outcomes of Patients with Acute Coronary Syndrome During Travel.

Cardiovascular disease is a major cause of death among travelers, but the clinical characteristics and clinical outcomes of patients who develop acute coronary syndrome (ACS) while traveling have not been assessed. We evaluated 2548 patients with ACS who underwent primary percutaneous coronary intervention (PCI) between 1999 and 2015 and compared the incidences of all-cause and cardiac death during follow-up between travelers and locals. We assessed 192 (7.

Changes in self-reported physical activity and health-related quality of life following 3-month astaxanthin supplementation in patients with heart failure: results from a pilot study.

Background: Astaxanthin has a strong antioxidant effect. We recently demonstrated that following 3-month astaxanthin supplementation, cardiac contractility and exercise tolerance improved, possibly through the suppression of oxidative stress in a small pilot study involving patients with heart failure with left ventricular systolic dysfunction. This is a sub-study of our pilot study to investigate whether improvements of selfreported physical activity and health-related quality of life were observed following 3-month astaxanthin supplementation.

Prognostic Effect of a Novel Simply Calculated Nutritional Index in Acute Decompensated Heart Failure.

The TCB index (triglycerides × total cholesterol × body weight), a novel simply calculated nutritional index based on serum triglycerides (TGs), serum total cholesterol (TC), and body weight (BW), was recently reported to be a useful prognostic indicator in patients with coronary artery disease. Thus, this study aimed to investigate the relationship between TCBI and long-term mortality in acute decompensated heart failure (ADHF) patients. Patients with a diagnosis of ADHF who were consecutively admitted to the cardiac intensive care unit in our institution from 2007 to 2011 were targeted.
