AIMS: Effective ventilation is crucial to save non-breathing newborns. We compared standard equipment for newborn resuscitation to a new Upright bag, in an area with high neonatal mortality. METHODS: Newborns requiring resuscitation at Haydom Lutheran Hospital, Tanzania, were ventilated with 230ml standard or 320ml Upright bag-mask by weekly non-blinded block randomization. A Laerdal Newborn Resuscitation Monitor collected ventilation data through a flow sensor between mask and bag and heart rate with electrocardiography electrodes...

This study aims to review pediatric pulmonary hypertension (PH) by comparing the guidelines of the European Society of Cardiology (ESC)/European Respiratory Society (ERS), the American Heart Association (AHA)/American Thoracic Society (ATS), and the European Pediatric Pulmonary Vascular Disease Network (EPPVDN). All three sets of guidelines define PH as having a mean pulmonary artery pressure of ≥25 mmHg and accept the validity of the World Health Organization (WHO) classification system. Every child with a high index of suspicion for PH should undergo an initial work-up of chest X-rays, electrocardiography, and echocardiography...

Background/Aims: Patients with symptoms of coronary artery disease (CAD) often display normal tracings or only nonspecific changes on electrocardiography (ECG). The aim of this study was to explore strategic elements of the ECG and other potential factors that are predictive of CAD in this scenario. Methods: This was an observational study of 142 patients with the chief complaint of chest pain, each of whom presented with a normal ECG and was subjected to emergency coronary angiography (CAG)...

OBJECTIVE: Metabolic alterations of intrauterine environment in diabetes mellitus (DM) lead to fetal cardiac dysfunctions that can persist after birth. The aim of the study was to assess the cardiovascular adaptation in infants born to diabetic mothers (IDM) with different degrees of glycometabolic control, in relation to revised guidelines for diagnosis of DM and quality improvements in neonatal care. MATERIALS AND METHODS: An observational case-control study was conducted on IDM with gestational, type 1, and type 2 DM...

BACKGROUND: Downward shifts in blood volume with changing position generally cause tachycardic responses. Age-related decreases in vagal nerve activity could contribute to orthostatic hypotension in older individuals. Fowler's position is a reclined position with the back between 30° and 60°, used to facilitate breathing, eating, and other routine daily activities in frail and elderly patients. OBJECTIVE: This study examined whether stroke volume (SV) was higher and heart rate (HR) lower in Fowler's position with an upright upper trunk than in Fowler's position with the whole trunk upright in both older and younger subjects, based on the assumption that lower HR would result from reduced sympathetic activation in older individuals...

OBJECTIVE: To evaluate the efficacy and tolerability of ranolazine as an add-on drug in chronic stable angina patients and the impact of ranolazine on the quality of life in chronic stable angina patients receiving other antianginal medications. MATERIALS AND METHODS: It was a prospective, open-label, hospital-based study involving 144 patients with chronic stable angina. First group received either metoprolol 12.5 or 25 mg/day or other antianginal medications; if the symptoms persist, the dose of metoprolol was increased to 50 mg/day, and to the second group, ranolazine 500 mg BD or 1 g OD was added along with metoprolol or others if the anginal attacks were not subsiding...

Aims: ST-depression at 24hECG has not been studied in relation to atrial fibrillation (AF) risk. We aimed to determine whether ST-depression at 24hECG was associated with incident AF in two Swedish population-based cohorts - a sub-cohort of the Malmö Diet and Cancer study (MDCS), and the cohort 'Men born in 1914', and to determine whether 24hECG could be used to predict AF development. Methods and results: There were 378 acceptable 24hECG recordings in the MDCS (mean age 64...

Hypertension is considered the major modifiable risk factor for premature cardiovascular disease, being more common than other important risk factors as cigarette smoking, dyslipidemia, or diabetes [1]. In older patients, systolic pressure and pulse pressure are more powerful determinants of cardiovascular events than diastolic pressure [2]. Importantly, the cardiovascular risk associated with hypertension is significantly affected by the presence or absence of other major risk factors [3]. Among imaging features, left ventricular hypertrophy (LVH) is the more common and early in patients with hypertension [4]...

Background -Optimal management of patients with stable chest pain relies on the prognostic information provided by noninvasive cardiovascular testing, but there are limited data from randomized trials comparing anatomic with functional testing. Methods -In the Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial, patients with stable chest pain and intermediate pre-test probability for obstructive coronary artery disease (CAD) were randomized to functional testing (exercise electrocardiography, nuclear stress, or stress echocardiography) or coronary computed tomography angiography (CTA)...

Introduction. Neonatal lupus erythematosus (NLE) is an acquired disease of the newborn caused by transplacental transfer of maternal anti-Ro/SSA, anti-La/SSB, and infrequently anti-U1 RNP antibodies. Methodology. This is a case report of a male infant delivered via Caesarean section at 36-week gestation following detection of fetal bradycardia during routine antenatal clinic visit. Results. The mother was seropositive for antinuclear antibody (ANA) and anti-Ro/SSA and had elevated erythrocyte sedimentation rate...

BACKGROUND Coronary artery embolization is an exceedingly rare cause of myocardial infarction, but a few cases in association with prosthetic mechanical valves have been reported. We report a case of embolic myocardial infarction caused by a thrombus in the left atrium with deranged coagulation profile in a patient with critical mitral stenosis under warfarinization. CASE REPORT A 22-year-old woman was taken to the catheterization lab for early coronary intervention in lieu of non-ST elevation myocardial infarction...

BACKGROUND: The choice of either anatomical or functional noninvasive testing to evaluate suspected coronary artery disease might affect subsequent clinical management and outcomes. OBJECTIVES: This study analyzed the association of initial noninvasive cardiac testing in outpatients with stable symptoms, with subsequent use of medications, invasive procedures, and clinical outcomes. METHODS: We studied patients enrolled in a Danish nationwide register who underwent initial noninvasive cardiac testing with either coronary computed tomography angiography (CTA) or functional testing (exercise electrocardiography or nuclear stress testing) from 2009 to 2015...

The present study introduces a detailed methodology which can be applied for objective evaluation and comparison of the acoustic parameters of medical stethoscopes using auscultation sounds as test signals. The described approach allows taking into account the acoustic coupling between the body of an auscultated patient and the chest piece of a stethoscope. Information obtained from additional, synchronized electrocardiography measurements is used to extract short, specific fragments of recordings, defined as acoustic events...
