BACKGROUND AND PURPOSE: Heart failure with preserved ejection fraction (HFpEF) is a systemic syndrome driven by co-morbidities and its pathophysiology is poorly understood. Several studies suggesting that dipeptidyl peptidase 4 (DPP4) might be involved in the pathophysiology of heart failure prompted experimental and clinical investigations of DPP4 inhibitors on cardiovascular system. The aim of our study was to determine whether DPP4 inhibitor sitagliptin (SITA) affects the progression of HFpEF independently from the effects on glycaemia...

We investigated the clinical situations and the present knowledge of Japanese cardiologists about coronary artery spasm before and after the establishment of guidelines for this condition in the real world. A questionnaire was developed regarding the number of cases of coronary angiography, percutaneous coronary intervention, and invasive/non-invasive spasm provocation tests before (2008) and after (2014) the establishment of the Japanese Circulation Society (JCS) guidelines for coronary artery spasm and the status of spasm provocation tests...

OBJECTIVE: The U.S. Agency for Healthcare Research and Quality's Prevention Quality Indicators comprise acute and chronic conditions for which hospitalization can be potentially prevented by high-quality ambulatory care. The Healthy Alaska 2020 initiative (HA2020) targeted reducing potentially preventable hospitalizations (PPH) for acute and chronic conditions among its health indicators. We estimated the PPH rate for adults aged ≥ 18 years in Alaska during 2010-2012. METHODS: We conducted a cross-sectional analysis of state-wide hospital discharge data obtained from the Healthcare Cost and Utilization Project and the Indian Health Service...

Right ventricular (RV) pacing has been reported to result in ventricular dyssynchrony, heart failure, and increased mortality. Pacing associated deterioration of left ventricular (LV) systolic function has been termed pacing-induced cardiomyopathy (PICM). While upgrading to biventricular pacing (BiVP) is an effective therapy for PICM, permanent His-bundle pacing (HBP) can be a physiological alternative to BiVP. We present a patient with PICM who responded dramatically to permanent HBP.

BACKGROUND: The choice of cardiac resynchronization therapy device, with (CRT-D) or without (CRT-P) a defibrillator, in patients with heart failure largely depends on the physician׳s discretion, because it has not been established which subjects benefit most from a defibrillator. METHODS: We examined the annual trend of CRT device implantations between 2006 and 2014, and evaluated the factors related to the device selection (CRT-D or CRT-P) for primary prevention of sudden cardiac death in patients with heart failure by analyzing the Japan Cardiac Device Treatment Registry (JCDTR) database from January 2011 and August 2015 (CRT-D, n=2714; CRT-P, n=555)...

INTRODUCTION: Most patients with HER2-positive breast cancer receive chemotherapy and trastuzumab. Data from adjuvant trials have shown that the combination of docetaxel, carboplatin and weekly trastuzumab (TCH) is well tolerated and as effective as anthracycline-containing regimes. Previous investigations on neoadjuvant treatment with taxanes, platinum salts and trastuzumab showed pathological complete remission (pCR) rates between 43.3 and 76%. To date, the longest published follow-up in this indication is 3 years...

Primary cardiac tumors are a rare occurrence with myxomas accounting for about half of the benign tumors. Once diagnosed, surgical resection is the standard of care. Our case describes a female in her 50s who underwent a myxoma resection under cardiopulmonary bypass via biatrial approach. Intraoperatively, the thin septal crux between the wall of the aorta and mitral valve was damaged during resection, requiring stem cell tissue matrix for repair. The patient also developed severe mitral regurgitation suggesting infarct to the left coronary system during resection, subsequently receiving a mechanical mitral valve and a saphenous vein bypass graft...

Systemic inflammation and localized macrophage infiltration have been implicated in cardiovascular pathologies, including coronary artery disease, carotid atherosclerosis, heart failure, obesity-associated heart dysfunction, and cardiac fibrosis. Inflammation induces macrophage infiltration and activation and release of cytokines and chemokines, causing tissue dysfunction by instigating a positive feedback loop that further propagates inflammation. Cytosolic adaptor caspase recruitment domain family, member 9 (CARD9) is a protein expressed primarily by dendritic cells, neutrophils, and macrophages, in which it mediates cytokine secretion...

RATIONALE: Heart failure (HF) and atherosclerosis share the underlying mechanisms of chronic inflammation followed by fibrosis. A highly conserved microRNA (miR), miR-33 is considered as a potential therapeutic target for atherosclerosis because it regulates lipid metabolism and inflammation. However, the role of miR-33 in HF remains to be elucidated. OBJECTIVE: To clarify the role of miR-33 involved in HF. METHODS AND RESULTS: We first investigated the expression levels of miR-33a/b in human cardiac tissue samples with dilated cardiomyopathy...

The complexity of central breathing disturbances during sleep has become increasingly obvious. They present as central sleep apnoeas (CSAs) and hypopnoeas, periodic breathing with apnoeas, or irregular breathing in patients with cardiovascular, other internal or neurological disorders, and can emerge under positive airway pressure treatment or opioid use, or at high altitude. As yet, there is insufficient knowledge on the clinical features, pathophysiological background and consecutive algorithms for stepped-care treatment...

BACKGROUND: Symptoms of breathlessness, fatigue, and ankle swelling are common in general practice but deciding which patients are likely to have heart failure is challenging. AIM: To evaluate the performance of a clinical decision rule (CDR), with or without N-Terminal pro-B type natriuretic peptide (NT-proBNP) assay, for identifying heart failure. DESIGN AND SETTING: Prospective, observational, diagnostic validation study of patients aged >55 years, presenting with shortness of breath, lethargy, or ankle oedema, from 28 general practices in England...

AIMS: Ischemia reperfusion (I/R) injury is an inevitable event arising during the cardiovascular diseases development and the process of potent surgical treatments. microRNAs (miRNAs) are critical regulators of multiple cell processes including I/R injury. The present study aims to quantify miRNA alterations and regulated genes upon hypoxia-reoxygenation (H/R) injury in a rat heart failure model comparing with normal cardiomyocytes. MAIN METHODS: Chronic heart failure was established by injecting doxorubicin (2mg/kg/week) for 6weeks, then H/R was performed on primary cultured cardiomyocytes isolated from normal and failed heart...

BACKGROUND: A corollary of the current population ageing in France is an increase in proximal femoral fractures (PFFs), particularly among centenarians. The outcomes of PFF in centenarians in France are unknown. We therefore conducted a retrospective study of centenarians with PFFs both to assess: 1) assess clinical outcomes according to geriatric and trauma scores, 2) and to determine whether routine surgery is warranted. HYPOTHESIS: Morbidity and mortality in a single-centre cohort of centenarians with surgically treated PFFs are consistent with previous reports...

REVIEW
Milton Packer, John J V McMurray
The magnitude of the clinical benefits produced by inhibitors of the renin-angiotensin system in heart failure has been modest, possibly because of the ability of renin-angiotensin activity to escape from suppression during long-term treatment. Efforts to intensify pharmacological blockade by use of dual inhibitors that interfere with the renin-angiotensin system at multiple sites have not yielded consistent incremental clinical benefits, but have been associated with serious adverse reactions. By contrast, potentiation of endogenous compensatory vasoactive peptides can act to enhance the survival effects of inhibitors of the renin-angiotensin system, as evidenced by trials that have compared angiotensin-converting enzyme inhibitors with drugs that inhibit both the renin-angiotensin system and neprilysin...

We report the first described case of a heterozygous p.R545H (c.1634 G > A) missense mutation in the LMNA gene with clinical features compatible with Dunnigan-type 2 familial partial lipodystrophy (FPLD2). The case presented as metabolic syndrome to a specialist clinical service and highlights the overlap between FPLD2 and the metabolic syndrome. The associations with type 2 diabetes mellitus, fatty liver disease, polycystic ovarian syndrome, and hypertriglyceridemia are highlighted. The importance of evaluating patients for these associated conditions is discussed, and the potential mechanisms of disease are briefly outlined...

Streptococcus pyogenes (group A streptococcus) causes rheumatic fever (RF) which later progresses towards rheumatic heart disease (RHD) in the susceptible individuals. RF and RHD both contribute towards increasing global burden of disease, especially in developing countries. RHD is one of the most common acquired heart diseases causing permanent damage to heart valves which ultimately leads to heart failure. In RHD, heart valve lesions are formed which are mediated by autoimmune reaction between streptococcal antigens (M protein and group A carbohydrate epitope GlcNAc) and heart tissues...

BACKGROUND Atrial fibrillation (AF) and renal dysfunction are two common comorbidities in patients with chronic heart failure with reduced ejection fraction (HFrEF). This study evaluated the effect of permanent AF on renal function in HFrEF and investigated the associations of atrial fibrillation, neutrophil gelatinase-associated lipocalin (NGAL), and neutrophil-to-lymphocyte ratio (NLR) with adverse clinical outcome. MATERIAL AND METHODS Serum NGAL levels measured by ELISA and NLR were compared between patients with sinus rhythm (HFrEF-SR, n=68), with permanent AF (HFrEF-AF, n=62), and a healthy control group (n=50)...
