Informal training in preclinical research may be a contributor to the poor reproducibility of preclinical cardiology research and low rates of translation into clinical research and practice. Mouse echocardiography is a widely used technique to assess cardiac structure and function in drug intervention studies using disease models. The inter-observer variability (IOV) of clinical echocardiographic measurements has been shown to improve with formalized training, but preclinical echocardiography lacks similarly critical standardization of training...

BACKGROUND: Validated cardiovascular (CV) risk estimates were developed in populations with relatively stable inflammatory levels. In rheumatoid arthritis (RA), patients routinely experience significant changes in inflammation. We tested whether changes in inflammation impact estimated CV risk as measured using validated population-based risk calculators. METHODS: We studied participants in a prospective RA cohort. We included participants who experienced a decrease (CRP decrease group) or increase (CRP increase group) of ≥10mg/L in C-reactive protein (CRP) at 2 consecutive time points, 1 year apart...

Congestive heart failure (CHF) is characterized by reduced heart rate variability. Although various methods to achieve parasympathetic withdrawal and sympathetic activation have been documented, stimulation of the vagal nerve (that is, vagal maneuvers) has not often been used to assess the autonomic impairment associated with disease progression in veterinary species. In this study, we investigated cardiac autonomic control in a naturally occurring canine model of mitral insufficiency by means of individual responses to oculocardiac reflex...

BACKGROUNDS: Pregnant women with congenital heart disease (CHD) are at risk of cardiovascular events during pregnancy as well as postpartum. The aim of our study is to address the feasibility of echocardiography-derived ventricular-arterial coupling during pregnancy and postpartum among women with CHD. METHODS: In 31 pregnant women with CHD, we performed serial echocardiography at the first and third trimesters, early and late postpartum. The indices of contractility (single-beat determined end-systolic elastance, Eesab ) and afterload (effective arterial elastance, Ea) were approximated on the basis of the systemic blood pressure and systemic ventricular volume...

INTRODUCTION: Neoplasms are the second most common diseases in western countries. Many patients with malignant diseases repeatedly present themselves in the emergency department (ED). Due to limited capacities, appropriate risk stratification strategies for cancer patients have to be developed. This study assesses if deceleration capacity (DC) of heart rate as a parameter of heart rate variability predicts mortality in emergency patients with malignant diseases. METHODS: Prospectively, 140 adults with different entities of malignant diseases who presented in the medical ED were included...

Peripheral arterial disease (PAD) is associated with augmented blood pressure (BP) and impaired coronary blood flow responses to exercise, which may increase cardiovascular risk. We investigated the effects of leg revascularization on the BP and coronary blood flow responses to exercise in PAD. Seventeen PAD patients (11 men, 66 {plus minus} 2 yr) performed single-leg plantar flexion exercise 24 hr before and one month following leg revascularization. BP and heart rate (HR) were measured continuously and rate pressure product (systolic BP x HR) was calculated as an index of myocardial oxygen demand...

Stress Echocardiography (SE) is an established diagnostic technique. For 40 years, the cornerstone of the technique has been the detection of regional wall motion abnormalities (RWMA), due to the underlying physiologically-relevant epicardial coronary artery stenosis. In the last decade, three new parameters (more objective than RWMA) have shown the potential to integrate and comple- ment RWMA: 1- B-lines, also known as ultrasound lung comets, as a marker of extra-vascular lung water, measured using lung ultrasound with the 4-site simplified scan symmetrically of the antero- lateral thorax on the third intercostal space, from mid-axillary to anterior axillary and mid- clavicular line; 2-left ventricular contractile reserve (LVCR), assessed as the peak stress/rest ratio of left ventricular force, also known as elastance (systolic arterial pressure by cuff sphygmomanome- ter/end-systolic volume from 2D echocardiography); 3- coronary flow velocity reserve (CFVR) on left anterior descending coronary artery, calculated as peak stress/rest ratio of diastolic peak flow velocity assessed using pulsed-wave Doppler...
