BACKGROUND: In aortic valve stenosis (AS), congestive heart failure (CHF) is a well-established symptom that indicates the need for surgical aortic valve replacement (SAVR). However, it is difficult to judge whether CHF symptoms such as dyspnea are caused by severe AS or other conditions, especially in elderly persons with restricted mobility or other organ complications. It is important to identify objective and noninvasive parameters associated with severe CHF symptoms in severe AS...

Pulmonary hypertension is a marker of disease severity. Exercise Doppler echocardiography (EDE) has proven to be feasible and reliable to assess pulmonary pressure. Increase in systolic pulmonary artery pressure (sPAP) has diagnostic and prognostic value in controlled studies. However, its value when assessed during routine examination in patients with cardiopulmonary diseases and resting sPAP > 35 mmHg is not clearly defined. Clinical documentation and offline reevaluation of digitally stored EDE examinations of patients with appropriate clinical indications for EDE were analyzed...

Background: Clinical decision-making in symptomatic patients after mitral valve (MV) repair remains challenging as echocardiographic reference values are lacking. In native MV disease intervention is recommended for mean transmitral pressure gradient (TPG) >15 mmHg or systolic pulmonary artery pressure (SPAP) >60 mmHg at peak exercise. Insight into standard stress echo parameters after MV repair may therefore aid to clinical decision-making during follow-up. Hypothesis: Stress echocardiography derived parameters in asymptomatic patients after successful MV repair differ from current guidelines for native valves...

In this study, we hypothesized that adding CO2 to an inhaled hypoxic gas mixture will limit the rise of pulmonary artery pressure (PAP) induced by a moderate exercise. Eight 20-year-old males performed four constant-load exercise tests on cycle at 40% of maximal oxygen consumption in four conditions: ambient air, normobaric hypoxia (12.5% O2 ), inhaled CO2 (4.5% CO2 ), and combination of hypoxia and inhaled CO2 . Doppler echocardiography was used to measure systolic (s)PAP, cardiac output (CO). Total pulmonary resistance (TPR) was calculated...

BACKGROUND: The relation between systolic pulmonary pressure (sPAP) and left atrium in patients with heart failure (HF) is unclear. Diastolic dysfunction, expressed as restrictive mitral filling pattern (RMP), and functional mitral regurgitation (FMR) are associated with both LA enlargement and increased sPAP. We aimed to evaluate whether atrial dilation might modulate the consequences of RMP and FMR on the pulmonary circulation of patients with HF with reduced ejection fraction (HFrEF)...

Growing data point to the overlap between psychosis and pathological processes associated with immunological dysregulation as well as inflammation. Notably, the recent discovery of antibodies against synaptic and neuronal cell membrane proteins such as anti-N-methyl-D-aspartate receptor provides more direct evidence of the etiological connection between autoimmunity and subsequent hazard of psychosis. Here, we advocate the use of term "autoimmune psychosis," as this term suggests that autoimmune disorders can masquerade as drug-resistant primary psychosis, and this subtype of psychosis has anatomical and immunological footprints in the brain, despite the frequent absence of structural abnormalities on conventional brain MRI...

INTRODUCTION: The Saskatoon Prostate Assessment Pathway (SPAP) was developed in 2013 in part to decrease the wait times between physician referral and biopsy for patients with suspected prostate cancer. Using an algorithm carefully designed to optimize appropriate prostate biopsy rates, physicians can directly refer patients for biopsy through the SPAP without seeing a urologist. All other patients are referred to the Saskatoon Urology Associates (SUA). The present study evaluates the performance of the algorithm...

Urotensin II (UII) has been reported to play a key role in pulmonary arterial hypertension (PAH) development. Doppler echocardiography, a noninvasive and simple tool, is recommended for diagnosing PAH. This study was designed to investigate the effect of urantide, a UII receptor antagonist, on the structure and function of the right ventricle in PAH rat models by Doppler echocardiography. A total of 60 male rats were divided into two groups: early- and late-treatment groups. Rats in the urantide and MCT (monocrotaline) subgroups were injected with 10 μg/kg urantide in the urantide group or an equal amount of normal saline in the MCT group 1 week after PAH model construction in the early-treatment group and 4 weeks after the construction in the late-treatment group...

OBJECTIVE: Elevated systolic pulmonary artery pressure (sPAP) is common among elderly patients with cardiac and pulmonary diseases. The lowest level of sPAP associated with increased mortality rate in octogenarians with cardiac diseases is however not sufficiently studied. Therefore, the present study aimed to identify the lowest level of sPAP associated with increased 5-year all-cause mortality in this patient group. DESIGN: Of 538 octogenarians presented at the three Sahlgrenska University Hospitals (Sahlgrenska, Östra and Mölndal) with either congestive heart failure (CHF) or acute coronary syndrome (ACS), only 302 patients who had undergone echocardiography with data on sPAP were included in the present study...
