Effects of the Combination of Candesartan plus Captopril in Elderly Patients with Anterior Myocardial Infarction
2000
Objective: To verify the feasibility, tolerability and efficacy of the combination of captopril (75 mg/day) and candesartan (8 mg/day) in early postinfarction phases of not thrombolysed and unreperfused anterior acute myocardial infarction (AMI) in elderly patients. Design and Patients: 71 patients (aged >65 years) hospitalised for anterior AMI were randomised in a double-blind manner into two groups: group A included 35 patients who received captopril 75 mg/day within 3 days of admission plus candesartan 4mg, as a first dose, and 8 mg/day successively; group B included 36 patients who received captopril 75 mg/day and placebo. 90 days after admission, patients underwent echocardiography to …
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…
Left ventricular volume determination using colour superpositioning of contrast echocardiograms
1995
Abstract Objective: To delineate the endocardium, selective colouring of contrast regions in left ventricular contrast echocardiograms was performed using digital image processing. Methods: Volume determinations were performed in end-diastolic and end-systolic frames before and after the injection of contrast agent into the left ventricle and were compared to cineventriculograms in 30 patients by two independent investigators. Results: The mean end-diastolic volume measured was 114 ± 44 ml in the native, 235 ± 79 ml in the contrast, 175 ± 70 ml in the color-superimposed (observer 1), and 187 ± 79 ml in the cineventriculographic images. Thus, native echocardiograms underestimated angiographi…
EpCAM and microvascular obstruction in patients with STEMI: a cardiac magnetic resonance study
2021
Abstract Funding Acknowledgements Type of funding sources: Public grant(s) – EU funding. Main funding source(s): This study was funded by “Instituto de Salud Carlos III” and “Fondos Europeos de Desarrollo Regional FEDER” Bachground. Microvascular obstruction (MVO) is negatively associated with cardiac structure and worse prognosis after ST-segment elevation myocardial infarction (STEMI). Epithelial cell adhesion molecule (EpCAM), involved in endothelium adhesion, is an understudied area in the MVO setting. Purpose. We aimed to evaluate whether EpCAM is associated with the appearance of cardiac magnetic resonance (CMR)-derived MVO and long-term systolic function in reperfused STEMI. Methods.…
P1462 Additive value of global longitudinal strain measurement in patients with known or suspected ischaemic heart disease undergoing stress echo
2020
Abstract BACKGROUND Speckle-tracking echocardiography (STE) can be applied in a large variety of clinical conditions. Global longitudinal strain (GLS) shows high diagnostic accuracy for the detection of myocardial ischemia as it reflects changes in subendocardial fibers deformation that are more exposed to ischemic damage, even before alterations in segmental kinetics are revealed. PURPOSE Aim of our study was to assess whether the measurement of global longitudinal strain during stress-echo can provide additional information compared to the assessment of conventional parameters such as left ventricular ejection fraction (LVEF) and wall motion abnormalities. We also evaluated the added valu…
Predictors of diuresis response to levosimendan administration in patients with acute heart failure
2021
Abstract Funding Acknowledgements Type of funding sources: None. Levosimendan, a calcium sensitizer and potassium channel-opener, is appreciated for its effects on systemic and pulmonary hemodynamic and for the relief of symptoms in acute heart failure (AHF). Positive effects of levosimendan on renal function have been also described. The aim of the present analysis was to assess the predictors of the diuresis response to levosimendan administration in high risk acute heart failure patients. Methods We analysed 34 consecutive patients admitted with high risk AHF to one centre and treated in intensive cardiac care unit. Levosimendan was administered on top of other treatment as a 24-hour in…

Prognostic Value and Kinetics of Soluble Neprilysin in Acute Heart Failure
2015
Abstract Objectives This study sought to examine the prognostic value of the soluble form of neprilysin (sNEP) in acute heart failure (AHF) and sNEP kinetics during hospital admission. Background sNEP was recently identified in chronic heart failure (HF) and was associated with cardiovascular outcomes. Methods A total of 350 patients (53% women, mean 72.6 ± 10.7 years of age) were included in the study. Primary endpoints were composites of cardiovascular death or HF hospitalizations at short-term (2 months) and long-term (mean: 1.8 ± 1.2 years) follow-up. sNEP was measured using an ad hoc–modified enzyme-linked immunosorbent assay, and its prognostic value was assessed using Cox regression …
Erfassung hämodynamischer Parameter bei Patienten mit chronischer thromboembolischer pulmonaler Hypertonie mittels MRT vor und nach Thrombendarteriek…
2003
Purpose: To evaluate the potential of MRI to grade cardiac impairment and pulmonary hypertension in patients with chronic thromboembolic pulmonary hypertension (CTEPH) in comparison with invasive pressure measurements before and after surgery. Materials and Methods: We examined 35 patients with CTEPH before and after pulmonary thromboendarterectomy (PTE). For assessment of hemodynamics, velocity-encoded segmented GE-sequences (pulmonary arteries and ascending aorta) and segmented cine GE-sequences along the short axis of the heart were performed. The analysis comprised calculation of ejection fractions, peak velocities, mean pulmonary arterial flow and vessel diameter. 10 volunteers served …
