OBJECTIVE: Galanin, a cotransmitter similar to neuropeptide Y (NPY), aggravates autonomic imbalance in systolic heart failure (HF) by attenuating vagal tonus after burst sympathetic activity. In animal HF models, galanin antagonists have improved cardiac function. To determine whether galanin is a promising therapeutic target in HF, we studied its concentrations in HF patients and evaluated its correlation with NPY, markers of humoral activity such as pro-BNP and copeptin, and echocardiographic parameters of HF severity...

BACKGROUND: Atrial fibrillation (AF) is a common arrhythmia that causes numerous visits to emergency departments (ED). The aim of the FinFib2 study was to evaluate whether treatment of patients with AF in ED is consistent with the contemporary European Society of Cardiology (ESC) management guidelines. Here we report the results of antiarrhythmic drug therapy (AAD) in ED. METHODS: All patients within the two-week study period whose primary reason for the ED visit was symptomatic AF were included into this prospective multicentre study...

BACKGROUND: Patients with advanced liver disease may develop portal hypertension that can result in variceal haemorrhage. Beta-blockers reduce portal pressure and minimise haemorrhage risk. These medications may attenuate measures of cardiopulmonary performance, such as the ventilatory threshold and peak oxygen uptake measured via cardiopulmonary exercise testing. AIM: To determine the effect of beta-blockers on cardiopulmonary exercise testing variables in patients with advanced liver disease...

The use of intra-aortic balloon counter-pulsation for circulatory support in pregnant women with cardiac failure is limited to several case reports. Few publications have addressed the use of intra-aortic balloon counter-pulsation during delivery. We report a case using prophylactic intra-aortic counter-pulsation during the management of a cesarean delivery in a patient with peripartum cardiomyopathy. A 28-year-old primigravid female at 37weeks of gestation was admitted with signs of worsening heart failure, and transthoracic echocardiography revealed a decreased left ventricular ejection fraction of 25%...

INTRODUCTION: Despite that heart rate (HR) control is one of the guideline-recommended treatment goals for heart failure (HF) patients, implementation has been painstakingly slow. Therefore, it would be important to identify patients who have not yet achieved their target heart rates and assess possible underlying reasons as to why the target rates are not met. MATERIALS AND METHODS: The survey of HR in patients with HF in Sweden (HR-HF survey) is an investigator-initiated, prospective, multicenter, observational longitudinal study designed to investigate the state of the art in the control of HR in HF and to explore potential underlying mechanisms for suboptimal HR control with focus on awareness of and adherence to guidelines for HR control among physicians who focus on the contributing role of beta-blockers (BBs)...

Chronic obstructive pulmonary disease (COPD) is the most common chronic respiratory disease and its prevalence is increasing worldwide, in both industrialised and developing countries. Its prevalence is ∼5% in the general population and it is the fourth leading cause of death worldwide. COPD is strongly associated with cardiovascular diseases; in fact, ∼64% of people suffering from COPD are treated for a concomitant cardiovascular disease and approximately one in three COPD patients die as a consequence of cardiovascular diseases...

REVIEW
Stéphane Laurent
Successful treatment of hypertension is possible with limited side effects given the availability of multiple antihypertensive drug classes. This review describes the various pharmacological classes of antihypertensive drugs, under two major aspects: their mechanisms of action and side effects. The mechanism of action is analysed through a pharmacological approach, i.e. the molecular receptor targets, the various sites along the arterial system, and the extra-arterial sites of action, in order to better understand in which type of hypertension a given pharmacological class of antihypertensive drug is most indicated...

INTRODUCTION: Hyperbaric oxygen (HBO₂) therapy is generally safe and well tolerated. However, known side effects do exist. Elevation in the blood pressure of patients undergoing HBO₂ therapy is a less defined potential side effect. We sought to better quantify effects of HBO₂ on blood pressure (BP) in patients undergoing HBO₂. METHODS: A retrospective chart review was performed on quality assurance data captured on all patients undergoing HBO₂ between March 2012 and October 2015 at a large tertiary referral university hospital hyperbaric center...

OBJECTIVES: The influence of choice of endpoint on trial size, duration, and interpretation of results was examined in patients with heart failure who were enrolled in BEST (Beta-blocker Evaluation of Survival Trial). BACKGROUND: The choice of endpoints in heart failure trials has evolved over the past 3 decades. METHODS: In the BEST trial, we used Cox regression analysis to examine the effect of bucindolol on the current standard composite of cardiovascular death or heart failure hospitalization (CVD/HFH) compared with the original primary mortality endpoint and the expanded composite that included emergency department (ED) visits...

Correct identification of a chemical substance in environmental samples based only on accurate mass measurements can be difficult especially for molecules > 300 Da. Here is presented the application of spectral accuracy, a tool for the comparison of isotope patterns toward molecular formula generation, as a complementary technique to assist in the identification process of emerging organic contaminants and their transformation products in surface water. A set of nine emerging contaminants (five antibiotics, an herbicide, a beta-blocker, an antidepressant and an antineoplastic) frequently found in surface water were spiked in methanol and surface water extracts at two different concentrations (80 and 300 μg L(-1))...

Central nervous system (CNS) tuberculosis (TB) is a rare but catastrophic event in patients with systemic lupus erythematosus (SLE). Here we report a case of cerebral TB in a patient with lupus myocarditis and nephritis, following cyclophosphamide immunosuppression. To our knowledge this is the first reported case of cerebral TB in SLE in a non-endemic country. A 31-year-old female with SLE and a history of regular travel to Kenya presented to our centre with clinical features of acute heart failure. She was diagnosed with severe lupus myocarditis, and a renal biopsy also confirmed lupus nephritis...

Severe ventricular arrhythmias are frequent during heart failure; they are a life-threatening condition due to the increased risk of sudden death. Efficient management remains limited in sub-Saharan Africa because of the limited or unavailable medical resources as automated implantable defibrillator (AID). We report the case of a 56-year old patient with non ischemic dilated cardiomyopathy with very low left ventricular ejection fraction (LVEF)who underwent AID implantation for primary prevention of sudden cardiac death due to ventricular arrhythmias in 2012...

Marfan syndrome is rarely diagnosed in the neonatal period because of variable expression and age-dependent appearance of clinical signs. The prognosis is usually poor due to high probability of congestive heart failure, mitral and tricuspid regurgitations with suboptimal response to medical therapy and difficulties in surgical management. The authors have studied two cases of Marfan syndrome in the newborn period. Two cases of neonatal Marfan syndrome, one male and one female, were diagnosed by characteristic physical appearance...
