Proton pump inhibitors (PPIs) are the most effective gastric acid-suppressing agents and the mainstay medical therapy for a series of acid peptic diseases. In general, the safety profile of PPIs is excellent. However, with long-term drug administration, the safety and potency of PPIs has been questioned. In the cardiovascular field, drug-drug interactions related to PPIs have been identified with particular attention regarding the use of PPIs combined with clopidogrel in patients with acute coronary syndrome. Currently, cardiovascular risks from PPIs may extend from patients with coronary artery disease to the general population. This review summarizes the possible cardiovascular risks in PPI users with no history of cardiovascular diseases and discusses possible biological mechanisms.

Advanced heart failure (HF) is sometimes complicated with brain impairment because of a microthrombosis caused by decreased left ventricular contraction or reduced brain circulation. Some patients may recover after left ventricular assist device (LVAD) implantation. However, little is known about the perioperative therapeutic strategy in patients suffering from such complications, particularly from a cardiac rehabilitation viewpoint. We report on a 58-year-old male patient with a previous history of poliomyelitis and a light paralysis in the left upper extremity, who suffered left hemiplegia with no evidence of stroke after hemodynamic deterioration. The combination therapy of perioperative cardiac rehabilitation and LVAD therapy improved his left hemiplegia as well as activities of daily living, and the patient was discharged on foot on postoperative day 72 after briefing the family on LVAD home management. Early initiation of cardiac rehabilitation before LVAD implantation may be a key for the smooth discharge and resocialization of patients suffering from brain impairment complicated with advanced HF.

The concept that coronary artery ectasia (CAE) is an inflammatory-related disease has been increasingly recognized. Periodontitis induced low-grade chronic systemic inflammation has been shown to be associated with cardiovascular diseases. The aim of the present study was to evaluate the association between periodontitis and CAE.Thirty-two patients with isolated CAE, and 28 age, sex and smoking status-matched subjects with normal coronary arteries (NCA) underwent full dental examinations. Periodontal disease was evaluated using the following clinical parameters; number of remaining teeth, plaque index (PI), gingival index (GI), bleeding on probing (BOP), and pocket depth (PD).Cases and controls did not differ according to their baseline characteristics and prevalence of traditional cardiovascular risk factors. Patients with isolated CAE had higher periodontal indices when compared to subjects with NCA (PD: 3.6 ± 1.26 mm versus 2.3 ± 0.79 mm; GI: 2.29 ± 0.86 versus 1.43 ± 1.19; BOP (%): 52.18 ± 20.1 versus 27.8 ± 10.9, P < 0.001, P < 0.05 and P < 0.05, respectively). Moreover, in multivariate analysis higher values for PD were found to be significant predictors for the likelihood of having coronary ectasia.The results of the present study demonstrate for the first time that there is an association between periodontitis and isolated CAE.

Pulmonary arterial hypertension (PAH) is a disease that imposes a significant burden on patients. Although multiple treatment options for PAH are available, head-to-head comparisons are difficult to conduct. Network meta-analysis (NMA) can be a useful alternative for direct comparison to estimate the relative effectiveness of multiple treatments. The objective of the present study was to conduct a systematic review and NMA to evaluate the relative effectiveness among oral PAH medications.Data collection was performed by searching the Cochrane Central Register of Controlled Trials (CENTRAL) and Ichushi-Web. Randomized controlled trials (RCTs) assessing at least 1 of the following 3 outcome measurements; 6-minute walk distance test (6MWD), WHO functional class (WHOFC), and mean pulmonary artery pressure (mPAP) were included (PROSPERO registration number: CRD42015016557). Outcomes were evaluated by estimating the differences in the mean change from baseline or by estimating the odds ratios. Analyses were performed using WinBUGS 1.4.3.Seven double-blind RCTs were eligible. NMA results showed similar improvements in 6MWD for all medications assessed. Bosentan and sildenafil caused a statistically significant improvement in WHOFC compared to other medications.The relative effectiveness of oral PAH medications could be compared using NMA, which suggested the superiority of bosentan and sildenafil in the improvement of WHOFC.

Ezetimibe has been reported to provide significant incremental reduction in low-density-lipoprotein cholesterol (LDL-C) when added to a statin; however, its effect on coronary atherosclerosis has not yet been evaluated in detail. The aim of this study was to investigate the add-on effect of ezetimibe to a statin on coronary atherosclerosis evaluated by intravascular ultrasound (IVUS).In this prospective randomized open-label study, a total of 51 patients with stable coronary artery disease (CAD) requiring percutaneous coronary intervention (PCI) were enrolled, and assigned to a combination group (n = 26, rosuvastatin 5 mg/day + ezetimibe 10 mg/day) or a monotherapy group (n = 25, rosuvastatin 5 mg/day). Volumetric IVUS analyses were performed at baseline and 6 months after the treatment for a non-PCI site. LDL-C level was significantly reduced in the combination group (-55.8%) versus that in the monotherapy group (-36.8%; P = 0.004). The percent change in plaque volume (PV), the primary endpoint, appeared to decrease more effectively in the combination group compared with the monotherapy group (-13.2% versus -3.1%, respectively, P = 0.050). Moreover, there was a significant group × time interaction in the effects of the two treatments on PV (P = 0.021), indicating the regressive effect of the combination therapy on PV was greater than that of monotherapy for subtly different values of baseline PV in the two treatment groups. Moreover, percent change in PV showed positive correlations with percent change of LDL-C (r = 0.384, P = 0.015).Intensive lipid-lowering therapy with ezetimibe added to usual-dose statin may provide significant incremental reduction in coronary plaques compared with usual-dose statin monotherapy.

Hypervolemic hyponatremia is often complicated with advanced heart failure together with increased excretion of sodium by diuretics. Tolvaptan, an oral vasopressin-2-receptor antagonist, has been previously reported to improve congestion and correct hyponatremia through increased excretion of free water. However, there is little evidence concerning the administration of tolvaptan in patients with stage D heart failure. We experienced 2 patients with stage D heart failure who received 3.75 mg/day of tolvaptan to correct hyponatremia before ventricular assist device implantation. It may be useful, even for patients with stage D heart failure, to administer a low dose of tolvaptan to treat hyponatremia before ventricular assist device implantation to avoid a drastic alteration in serum sodium concentration perioperatively.

The importance of atrial fibrillation (AF) as a cause of mortality and morbidity has prompted research on its pathogenesis and treatment. Recognition of AF risk factors is essential to prevent it and reduce the risk of death. Hyperuricemia has been widely accepted to be associated with the incidence of paroxysmal or persistent AF, as well as to the risk of AF in post cardiovascular surgery patients. The possible explanations for this association have been based on their relation with either oxidative stress or inflammation. To investigate the link between hyperuricemia and AF, it is necessary to refer to hyperuricemia-induced atrial remodeling. So far, both ionic channel and structural remodeling caused by hyperuricemia might be plausible explanations for the occurrence of AF. Inhibition of xanthine oxidase and nicotinamide adenine dinucleotide phosphate (NADPH)-oxidase, or the use of antioxidants, along with serum uric acid (SUA) level reduction to prevent inflammation, might be useful. Uric acid transporters (UATs) play a key role in the regulation of intracellular uric acid concentration. Intracellular rather than serum uric acid level is considered more important for the pathogenesis of AF. Identification of UATs expressed in cells is thus important, and targeting UATs might become a potential strategy to reduce the risk of hyperuricemia-induced atrial fibrillation.

Marfan syndrome (MFS) is an autosomal dominant heritable disorder of connective tissue that affects the cardiovascular, skeletal, ocular, pulmonary, and nervous systems and is usually caused by mutations in the FBN1 gene, which encodes fibrillin-1. MFS is traditionally considered to result from the structural weakness of connective tissue. However, recent investigations on molecular mechanisms indicate that increased transforming growth factor-β (TGF-β) activity plays a crucial role in the pathogenesis of MFS and related disorders, such as Loeys–Dietz syndrome (LDS), which is caused by mutation in TGF-β signaling-related genes. In addition, recent studies show that angiotensin II type 1 receptor (AT1R) signaling enhances cardiovascular pathologies in MFS, and the angiotensin II receptor blocker losartan has the potential to inhibit aortic aneurysm formation. However, the relationship between TGF-β and AT1R signaling pathways remains poorly characterized. In this review, we discuss the recent studies on the molecular mechanisms underlying cardiovascular manifestations of MFS and LDS and the ensuing strategies for management.

Vaccines are commonly used as a preventive medicine for infectious diseases worldwide, however, clinical trials on an amyloid beta vaccine for Alzheimer’s disease represents a new concept in the field of vaccinations. Several recent studies indicate the potential of therapeutic vaccines as well as classical vaccines as preventive medicines. A number of therapeutic vaccines for cancer have been developed as novel immunotherapies. Their targets are usually specifi c antigens in cancer cells, allowing activated cytotoxic T cells (CTLs) to attach and remove the antigen-presenting cancer cells. Recently, we and others have attempted to develop a therapeutic vaccine against hypertension. The vaccine target is angiotensin II (AngII), and induced anti-AngII antibodies could efficiently ameliorate high blood pressure. However, because AngII is an endogenous hormone, we must avoid the induction of autoimmune diseases by administration of an AngII vaccine. Therefore, our system was used to design a therapeutic vaccine that elicits anti-AngII antibodies without CTL activation against AngII. Because the target antigen itself does not include T cell epitopes, the immunogenic molecule (ie, KLH) provides antigen that supports the activation of T cells. In particular, helper T cells may activate B cells that produce antibodies against our specific antigen. In this review, we will explain our concept of therapeutic vaccines based on our recent data.

Urinary albumin excretion is a predictor of cardiovascular death. Cardiac rehabilitation (CR) with exercise training (ET) has been shown to improve exercise capacity and prognosis in patients with cardiovascular disease (CVD). However, it remains unclear whether CR reduces urinary albumin excretion in CVD patients. We performed a retrospective, observational study using data obtained from 98 male CVD patients without macroalbuminuria and estimated glomerular filtration rate (eGFR) < 30 mL/minute/1.73 m2 who participated in CR with ET during hospitalization. Twenty-three patients continued supervised ET for 6 months (supervised group) and 75 patients quit supervised ET (non-supervised group). The supervised ET program consisted of 60 minutes of supervised sessions 1-3 times a week and 30-60 minutes of home exercise at least twice a week. Urinary albumin/creatinine ratio (ACR) was significantly decreased in the supervised group at 6 months after enrollment (43 ± 71 mg/g to 17 ± 20 mg/g creatinine, P < 0.05) but not in the non-supervised group. eGFR was unchanged in the supervised group but was significantly decreased in the non-supervised group (72 ± 18 mL/minute/1.73 m2 to 67 ± 17 mL/minute/1.73 m2, P < 0.001). The results of multiple regression analysis showed that only supervised ET was an independent contributor to ΔACR. CR with supervised ET decreased urinary albumin excretion without deterioration of renal function. These findings suggest that continuation of a supervised ET program is associated with reduction in the development of CVD and reduction in cardiovascular morbidity and mortality in CVD patients.

In patients with acute myocardial infarction (MI), coronary microvasculatures are often damaged irreversibly due to myocardial ischemia and reperfusion, and flow to the previously ischemic myocardium is markedly reduced, a phenomenon known as the “no-reflow phenomenon”. Percutaneous coronary intervention (PCI) may accelerate embolization of plaque gruels and microthrombi to the microvessels, which further reduces tissue perfusion. The extent of the no-refl ow zone correlates with infarct size, and it has additional prognostic information. Recent advances in imaging modalities have enabled us to diagnose the no-reflow phenomenon and to assess the mechanisms of the no-refl ow phenomenon. Pharmacological interventions and catheter-based devices to retrieve embolic materials have been proposed, and some of them are associated with improvement in clinical outcomes. Thus, we should keep in mind that only the achievement of complete microvascular perfusion is associated with better functional and clinical outcomes in patients with acute MI.

Central aortic pressure waveform (AoPW) is the summation of a forward–traveling wave generated by the left ventricle and a backward-traveling wave caused by the reflection of the forward wave. The aim of this study was to evaluate the effect of ventricular-vascular coupling on the morphology of AoPW in chronic heart failure patients with different degrees of left ventricular systolic dysfunction (LVSD) using pulse wave analysis (PWA). PWA of AoPW and left ventricular (LV) function were evaluated by applanation tonometry in 26 control subjects, in 12 patients with left ventricular ejection fraction (LVEF) ≤ 30%, and in 14 patients with LVEF > 30%. Augmentation pressure, augmentation index, wasted energy, and ejection duration were lower in patients with LVEF ≤ 30% than in those with LVEF > 30% and in control subjects. Furthermore, augmentation index showed an inverse correlation with Doppler mitral E-wave amplitude (r = -0.40; P = 0.04) and E/A ratio (r = -0.42; P = 0.03) and a direct correlation with deceleration time of mitral E-waves (r = 0.39; P = 0.04). In patients with severe LVSD (LVEF ≤ 30%), aortic wave reflections negatively interfere with LV function and induce a shortening of ejection duration. In contrast, AoPW is similar in patients with moderate LVSD (LVEF > 30%) and in control subjects.

Music therapy (MT) has been used in geriatric nursing hospitals, but there has been no extensive research into whether it actually has beneficial effects on elderly patients with cerebrovascular disease (CVD) and dementia. We investigated the effects of MT on the autonomic nervous system and plasma cytokine and catecholamine levels in elderly patients with CVD and dementia, since these are related to aging and chronic geriatric disease. We also investigated the effects of MT on congestive heart failure (CHF) events.Eighty-seven patients with pre-existing CVD were enrolled in the study. We assigned patients into an MT group (n = 55) and non-MT group (n = 32). The MT group received MT at least once per week for 45 minutes over 10 times. Cardiac autonomic activity was assessed by heart rate variability (HRV). We measured plasma cytokine and catecholamine levels in both the MT group and non-MT group. We compared the incidence of CHF events between these two groups. In the MT group, rMSSD, pNN50, and HF were significantly increased by MT, whereas LF/HF was slightly decreased. In the non-MT group, there were no significant changes in any HRV parameters. Among cytokines, plasma interleukin-6 (IL-6) in the MT group was significantly lower than those in the non-MT group. Plasma adrenaline and noradrenaline levels were significantly lower in the MT group than in the non-MT group. CHF events were less frequent in the MT group than in the non-MT group (P < 0.05). These findings suggest that MT enhanced parasympathetic activities and decreased CHF by reducing plasma cytokine and catecholamine levels.

Multiple trabeculation and a higher ratio of non-compacted to compact myocardial layer were found in the <i>Myh6:Dtna</i>^<i>N49S</i> mice compared to the controls. The transgenic mice also showed left ventricular (LV) dilation and cardiac systolic dysfunction. In conclusion, overexpression of the <i>DTNA</i>-p.N49S mutation in a mouse heart can be responsible for the phenotype of deep trabeculation, dilated cardiomyopathy, and cardiac dysfunction, which resembles the phenotype of LVNC.</p>

The risk of cardiovascular disease increases with age, causing chronic disability, morbidity, and mortality in the elderly. Cardiovascular aging and disease are characterized by heart failure, cardiac ischemia-reperfusion injury, cardiomyopathy, hypertension, arterial stiffness, and atherosclerosis. As a cell ages, damaged organelles and abnormal proteins accumulate. A system for removing these cytoplasmic substrates is essential for maintaining homeostasis. Autophagy assists tissue homeostasis by forming a pathway by which these substances are degraded. Growing evidence suggests that autophagy plays a role in age-related and disease states of the cardiovascular system, and it may even be effective in preventing or treating cardiovascular disease. On the other hand, overexpression of autophagy in the heart and arteries can produce detrimental effects. We summarize the current understanding of the close relationship between autophagy and cardiovascular senescence.

To investigate the postprocedural cardiovascular events and vascular outcomes, including hand ischemia and neurological compromise, after transulnar (TU) catheterization in ipsilateral radial artery occlusion.Previous randomized trials have shown that the transulnar (TU) approach for coronary angiogram and intervention has safety and outcomes similar to those of the transradial (TR) approach. However, the safety of the TU procedure when ipsilateral radial artery occlusion occurs is unknown.We retrospectively reviewed 87 TU cases with ipsilateral radial artery occlusion confirmed by a forearm angiogram. Eighty percent of these patients had a history of ipsilateral radial artery cannulation or surgery. We avoided the use of over-sized sheaths or applied a sheathless approach during surgery.No ulnar artery occlusion was observed by subsequent Doppler ultrasound or pulse oximetry. No patient developed hand ischemia or serious complications requiring surgery or blood transfusion during the follow-up period of 32.2 ± 24.0 months. Review of the preprocedural forearm angiograms showed that 95.7% of the patients possessed significant collaterals supplying flow from the interosseous artery to the occluded radial artery remnant. Thus, the blood circulation to the palmar arch and digital vessels was maintained even when the ulnar artery was temporarily occluded by an in-dwelling ulnar arterial sheath.TU catheterization was safe in patients with coexisting ipsilateral radial artery occlusions and feasible for use in complex intervention procedures. Cautious manipulation of ulnar artery cannulation and hemostasis helped decrease the risk of hand ischemia.

Down syndrome (DS) is a common chromosome 21 abnormality disease, leading to various health problems, especially atrioventricular septal defect (AVSD). Genes and microRNAs (miRNAs) associated with AVSD in DS patients still need in-depth study.Gene expression data (GSE34457) of 22 DS patients without congenital heart disease and 7 DS patients with AVSD were downloaded from Gene Expression Omnibus. After screening differentially expressed genes (DEGs) based on limma package in R (criteria: P < 0.05 and |log2 fold change (FC)| > 0.5), pathway and functional enrichment analyses were performed using the online software DAVID (criterion: P < 0.05). The protein-protein interaction (PPI) networks of DEGs were constructed based on the online server STRING (criterion: combined score > 0.4). Next, miRNAs that targeted DEGs were predicted based on Webgestalt (criteria: P < 0.05 and target DEGs ≥ 2), and miRNA-DEG regulatory networks were visualized through Cytoscape.A total of 179 DEGs were identified. Next, 5 functions and 1 pathway were enriched by up-regulated DEGs, while 4 functions were enriched by down-regulated DEGs. Furthermore, miRNA-DEG regulatory networks were constructed. IL1B was the hub-gene of PPI networks, and AUTS2 and KIAA2022 were predicted to be targeted by miR-518a, miR518e, miR-518f, miR-528a, and miR-96.IL1B, IL12RB2, AUTS2, and KIAA2022 might participate in AVSD in DS patients, and AUTS2 and KIAA2022 might be targeted by miR-518a, miR-518e, miR-518f, miR-528a, and miR-96. The identified genes and miRNAs might provide a theoretical basis for understanding AVSD in DS patients.

Cardiac regeneration strategies using stem cells have shown variable and inconsistent results with respect to patient cardiac function and clinical outcomes. There has been increasing consensus that improving the efficiency of delivery may improve results. The Helix transendocardial delivery system (BioCardia Inc.) has been developed to enable percutaneous transendocardial biotherapeutic delivery. Therefore, we evaluated cell retention using this unique system compared with direct transepicardial injection and intracoronary infusion in an animal model.Twelve healthy swine were used in this study. 18Fluorodeoxyglucose (FDG)-labeled bone marrow mononuclear cells were delivered via percutaneous transendocardial route using the Helix system (TE group, n = 5), via direct transepicardial injection using a straight 27-gauge needle in an open chest procedure (TP group, n = 4), or via percutaneous intracoronary (IC) infusion (IC group, n = 3). One hour after cell delivery, the distribution of injected cells within the myocardium was assessed by PET-CT. Regions of interest were defined and their signals were compared in each group. Retention rates were calculated as a percentage of the comparing signal.The distribution of injected cells in the myocardium was higher in the TE group (17.9%) than in the TP group (6.0%, versus TE, P < 0.001) and the IC group (1.0%, versus TE, P < 0.001). Consistent with previous reports, there were signal distributions in the lungs, liver, and kidneys in qualitative whole body PET assessment.TE cell delivery using a helical infusion catheter is more efficient in cell retention than either TP delivery or IC delivery using PET-CT analysis.

Gut microbiota have been attracting increased attention in many fields of medicine recently. We can perform a comprehensive analysis of gut microbiota using next-generation sequencing techniques together with bioinformatics technology, which expands our knowledge of a large ecosystem consisting of a host and gut microbiota. We summarize some reports about the correlations between gut microbiota and metabolic disorders, particularly atherosclerosis, and discuss future directions for the diagnostic or therapeutic potential of gut microbiota. To take simple examples, we demonstrated that the order Lactobacillales was significantly increased; while the phylum Bacteroidetes was significantly decreased in coronary artery disease (CAD) patients compared with controls or healthy volunteers. The characteristics of gut microbiota in type 2 diabetes and dyslipidemia have been reported. However, these studies have limitations, and the biological significance of gut microbiota and the causal relationships are still controversial. We hope the reports listed in this review article might lead to the development of a novel therapy to prevent CAD via modulating gut microbiota or their metabolites.

Rotational atherectomy to an angulated calcified lesion is always challenging. The risk of catastrophic complications such as a burr becoming stuck or vessel perforation is greater when the calcified lesion is angulated. We describe the case of an 83-year-old female suffering from unstable angina. Diagnostic coronary angiography revealed an angulated calcified lesion in the proximal segment of the right coronary artery. We performed rotational atherectomy to the lesion, but intentionally did not advance the rotational atherectomy burr beyond the top of the angulation. We controlled the rotational atherectomy burr and stopped it just before the top of the angulation to avoid complications. Following rotational atherectomy, balloon dilatation with a non-compliant balloon was performed, and drug-eluting stents were successfully deployed. In this manuscript, we provide a review of the literature on this topic, and discuss how rotational atherectomy to an angulated calcified lesion should be performed.
