May Measurement Month 2018 : an analysis of blood pressure screening campaign results from Poland

2020

Abstract Hypertension remains the most important cardiovascular risk factor in Poland. May Measurement Month is a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for blood pressure (BP) screening and demonstrating the potential of the opportunistic BP measurements. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in 146 sites in May 2018. Blood pressure was measured in 6450 subjects (mean age: 41 ± 15 years; 59% females). After multiple imputation, the age and sex standardized systolic and diastolic BP was 126.7/78.4 mmHg in the whole analysed group, 132.8/81.3 mmHg in subjects tak…

Echocardiography to estimate high filling pressure in patients with heart failure and reduced ejection fraction

2020

Aims: Echocardiographic assessment of left ventricular filling pressures is performed using a multi-parametric algorithm. Unselected sample of patients with heart failure with reduced ejection fraction (HFrEF) patients may demonstrate an indeterminate status of diastolic indices making interpretation challenging. We sought to test improvement in the diagnostic accuracy of standard and strain echocardiography of the left ventricle and left atrium (LA) to estimate a pulmonary capillary wedge pressure (PCWP) > 15 mmHg in patients with HFrEF. Methods and results: Out of 82 consecutive patients, 78 patients were included in the final analysis and right heat catheterization, and echocardiogram…

Normalwerte für die Dobutamin-Streßechokardiographie*

2008

UNLABELLED Dobutamine stress echocardiography having established itself as a sensitive method for diagnosing coronary heart disease, even in the absence of normative values, the physiological haemodynamics as well as the physiological values for global and regional left ventricular myocardial function were measured. TEST PERSONS AND METHODS 14 healthy subjects (ten men, four women; median age 25 [range 21-32] years) underwent dobutamine stress echocardiography according to an internationally practised dosage steps protocol (5-40 micrograms/kg/min with additional 0.5 mg atropine at 40 micrograms). RESULTS Maximal infusion rate achieved a serum dobutamine level of 1.67 micrograms/ml with mini…

0283: Correlation between N-terminal pro-natriuretic peptide levels and left atrial size in patients with left ventricular systolic dysfunction

2014

BackgroundElevated N-terminal Pro B-type Natriuretic Peptide (NT Pro-BNP) levels are correlated with the severity of left ventricular systolic dysfunction and left ventricular filling alterations. Besides, left atrial (LA) size is believed to reflect chronic diastolic dysfunction.AimEvaluate the relationship between NT Pro-BNP and LA size.Methods81 patients (77.7% males; mean age, 61.55±15 years), with left ventricular systolic dysfunction (left ventricular ejection fraction [LVEF] 20cm2 was 1188pg/mL (area under the receiver-operating characteristic curve [AUC] 0.83 [0.71–0.93], p<0.0001, sensitivity 77.6%, specificity 75%).ConclusionThe present study shows that plasma NT Pro-BNP levels is…

Rheumatoid arthritis affects left ventricular mass: Systematic review and meta-analysis.

2015

Abstract Background Cardiovascular disease represents one of the most important extra-articular causes of morbidity and mortality in patients with rheumatoid arthritis (RA). Evidences showed that several cardiac structures can be affected during the course of the disease as well as abnormalities of left ventricular diastolic filling. Contrasting data are available about left ventricular mass (LVM) involvement in patients asymptomatic for cardiovascular disease. The purpose of this systematic review and meta-analysis is to summarize the effects of RA on LVM in rheumatoid arthritis patients without cardiovascular disease. Methods A systematic research of the current case–control studies was c…

Impact of left atrial diameter on outcome in patients undergoing edge-to-edge mitral valve repair: results from the German TRAnscatheter Mitral valve…

2020

Abstract Background Left atrium (LA) dimension is a marker of disease severity and outcome in primary and secondary mitral regurgitation. In transcatheter mitral valve repair LA enlargement might additionally impact on device handling and technical success through an altered anatomy and atrial annular dilatation. Methods Data from the multicenter German transcatheter mitral valve intervention registry “TRAMI” were used to analyse the association of baseline LA diameter by tertiles and efficacy, safety and long-term clinical outcome in patients undergoing edge-to-edge repair with the MitraClip. Results In 520 of 843 patients prospectively enrolled in TRAMI baseline LA diameter were reported …

Cardiac computed tomography assessment of the near term impact of percutaneous ventricular restoration therapy (parachute®) on mitral valve geometry

2015

Objectives The aim of current study is to assess the near term impact of percutaneous ventricular restoration therapy (PVR), Parachute® on mitral valve (MV) geometry by cardiac computed tomography (CCT). Background Recent data demonstrates the feasibility of PVR for treatment of post anterior myocardial infarction (MI) heart failure. Little is known, however, about the interaction of the device and left ventricular structures, particularly the MV apparatus. Methods This is a retrospective Core Laboratory analysis of Parachute Trials’ CCT data. Patients with paired (before and after Parachute implant) CCT acquisitions were included into analysis. MV geometric parameters were measured. Result…

Low target birth weight or growth retardation? Umbilical Doppler flow velocity waveforms and histometric analysis of fetoplacental vascular tree

1993

Objective: The placental vascular architecture of small-for-gestatonal-age fetuses seems to have an impact on the flow patterns in the umbilical arteries. Study Design: Blood flow velocity waveforms of the umbilical arteries were measured by Doppler ultrasonography in nine small-for-gestational-age fetuses with elevated systolic/diastolic ratios of the umbilical arteries, seven small-for-gestational-age fetuses with normal flow patterns, and 14 appropriate-for-gestational-age fetuses with normal flow patterns. After delivery histomorphometric placental investigations were performed. Results: Reduced end-diastolic flow velocities were significantly associated with both a reduction of vascula…
