Outcome of patients with right heart thrombi: the Right Heart Thrombi European Registry.

Our aim was the assessment of the prognostic significance of right heart thrombi (RiHT) and their characteristics in pulmonary embolism in relation to established prognostic factors.138 patients (69 females) aged (mean±sd) 62±19 years with RiHT were included into a multicenter registry. A control group of 276 patients without RiHT was created by propensity scoring from a cohort of 963 contemporary patients.

Echocardiographic Correlates of Abnormal Liver Tests in Patients with Exacerbation of Chronic Heart Failure.

Background: Elevated total bilirubin (TB) and transaminases are frequently reported in patients with heart failure and are related to their worse prognosis. On the basis of hemodynamic data from previous studies, the investigators hypothesized that elevated bilirubin and transaminases are associated with different patterns of cardiac remodeling and dysfunction in patients with heart failure (i.e.

Pulse wave velocity correlates with aortic atherosclerosis assessed with transesophageal echocardiography.

Aortic pulse wave velocity (PWV) is a noninvasive vascular parameter that is related to cardiovascular risk. We studied the relationship between aortic PWV and aortic atherosclerosis assessed with transesophageal echocardiography (TEE). The patients referred for TEE before electrical cardioversion of atrial fibrillation were included in the study.

Echocardiographic evaluation of external iliac artery Doppler waveform in patients with coronary artery disease.

Visual interpretation of the Doppler waveform in the common femoral or distal external iliac artery (EIA) was reported to be useful in screening for proximal peripheral artery occlusive disease (PAOD) in patients with lower limb ischemia. Commonly patients with coronary artery disease (CAD) referred for echocardiography have coexistent arterial pathology. Therefore, we decided to study whether echocardiographic evaluation of the distal EIA flow can be useful for detection of PAOD in patients with CAD.

Echocardiographic evaluation of aorto-iliac occlusive disease.

Several studies demonstrated feasibility of visual assessment of the common femoral artery Doppler waveform, in an indirect evaluation of aorto-iliac segment stenosis. Patients with cardiac diseases referred for echocardiography often have coexistent arterial pathology. Since many of them are potential candidates for endovascular procedures, we decided to study, whether echocardiography can be useful for detection of aorto-iliac occlusive disease.

Abdominal aortic Doppler waveform in patients with aorto-iliac disease.

Objectives: The mid-systolic deceleration (notch) in the proximal descending aortic Doppler waveform was reported to be common in patients with aorto-iliac disease. However, evaluation of the descending aorta is limited to echocardiography and may be technically difficult. Therefore, we decided to check whether similar Doppler flow disturbance can be found in abdominal aorta, which is easily evaluated in wider range of patients undergoing general abdominal and vascular ultrasound, as well as echocardiography.

Descending aortic Doppler flow pattern in patients with proximal peripheral artery disease.

Midsystolic deceleration (notch) in pulmonary pulse-wave (PW) Doppler flow is a common finding in patients with pulmonary embolism. The possible mechanism involves early reflection of pressure wave from proximal embolic sites. The aim of this study was to evaluate with PW Doppler whether occlusion or significant stenosis in the distal aorta or iliac arteries might produce a similar midsystolic notch in descending aortic flow.

Biomarker-based risk assessment model in acute pulmonary embolism.

Aims: Despite growing interest in biomarkers application for risk evaluation in acute pulmonary embolism (APE), no decision-making levels have been defined.

Methods And Results: We developed a biomarker-based risk stratification in 100 consecutive, normotensive on admission, APE patients (35 males, 65 females, 62+/-18 years). On admission serum NT-proBNP and cardiac troponin T (cTnT) levels were assessed and echocardiography was performed.

Does saddle embolism influence short-term prognosis in patients with acute pulmonary embolism?

Background: In some patients with acute pulmonary embolism (APE) thrombi may lodge at the levels of the bifurcation of pulmonary trunk and extend into both main pulmonary arteries, forming so-called saddle embolism (SE).

Aim: To assess the incidence of SE and whether it is associated with an increased risk of complicated clinical course.

Methods: We studied 150 consecutive patients (94 females, 56 males) aged 63.

Plasma neuropeptide Y immunoreactivity influences left ventricular mass in pheochromocytoma.

Unlabelled: Left ventricular hypertrophy (LVH) in patients with arterial hypertension is closely related to the levels of blood pressure (BP), catecholamines, angiotensin II and other mitogenic peptides. Pheochromocytoma (pheo) is a type of hypertension caused by excessive production of catecholamines. The aim of this study was to determinate if left ventricular hypertrophy in patients with pheochromocytoma is related to catecholamines and neuropeptide Y (NPY).

N-terminal pro-brain natriuretic peptide in patients with acute pulmonary embolism.

Plasma brain natriuretic peptide (BNP), released from myocytes of ventricles upon stretch, has been reported to differentiate pulmonary from cardiac dyspnoea. Limited data have shown elevated plasma BNP levels in acute pulmonary embolism (APE), frequently accompanied by dyspnoea and right ventricular (RV) dysfunction. The aim of this study was to assess plasma N-terminal proBNP (NT-proBNP) in APE, and to establish whether it reflects the severity of RV overload and if it can be used to predict adverse clinical outcome.

Cardiac troponin T monitoring identifies high-risk group of normotensive patients with acute pulmonary embolism.

Study Objectives: Indications for thrombolysis in normotensive patients with pulmonary embolism (PE), based on the presence of right ventricular (RV) overload during transthoracic echocardiography (TTE), are controversial. We checked whether the monitoring of cardiac troponin T (cTnT) might help in risk stratification by detecting patients with RV myocardial injury.

Patients And Design: We studied 64 normotensive patients (30 women and 34 men) with a mean (+/- SD) age of 61.

Proximal pulmonary emboli modify right ventricular ejection pattern.

Analysis of the systolic flow velocity curve (SFVC) in the right ventricular outflow tract is considered as an alternative to the tricuspid valve pressure gradient (TVPG) method for echo-Doppler assessment of pulmonary arterial pressure (P(pa)). The present study checked whether or not SFVC is affected by the cause of pulmonary hypertension. Doppler recordings of 86 patients (39 female, aged 55.

Regression of left ventricular hypertrophy in hypertensive patients after 1 year of treatment with rilmenidine: a double-blind, randomized, controlled (versus nifedipine) study.

Objective: To assess the effect of 1-year treatment with rilmenidine, an oxazoline compound that exerts its antihypertensive effects through binding to imidazoline receptors in the brainstem, on left ventricular hypertrophy (LVH) secondary to essential, mild-to-moderate hypertension [supine diastolic blood pressure (DBP)95-115 mmHg].

Methods: We performed a double-blind, randomized, controlled (versus slow-release nifedipine) trial. Adjustment of treatment took place every month (M) between inclusion (MO) and an evaluation after 6 months (M6), then during M9 and after 1 year (M12) to achieve supine DBP values < or = 90 mmHg.

Noninvasive diagnosis of suspected severe pulmonary embolism: transesophageal echocardiography vs spiral CT.

Objective: Patients with pulmonary embolism (PE) and echocardiographic signs of right ventricular overload have worse prognosis and may require aggressive therapy. Unequivocal confirmation of PE is required before thrombolysis or embolectomy. This study compares the value of transesophageal echocardiography (TEE) and spiral CT (sCT) in direct visualization of pulmonary artery thromboemboli in patients with suspected PE and echocardiographic signs of right ventricular overload.

Transoesophageal echocardiography for definitive diagnosis of haemodynamically significant pulmonary embolism.

Transesophageal echocardiographic evaluation of right and left pulmonary arteries, up to the origin of their lobar branches, was prospectively performed with a single plane probe in 32 consecutive patients (18 M, 14 F, aged 55.5 +/- 14.6, from 32 to 80 years) with clinical or echocardiographic suspicion of pulmonary embolism, who met transthoracic echocardiographic criteria of right ventricular overload.

Elevated endothelin-1 plasma concentration in patients with essential hypertension.

Background: Endothelin-1 (ET-1) may play an important role in the development and maintenance of hypertensive states. In patients with essential hypertension, ET-1 plasma concentration increases or remains unchanged. The aim of the present study was to investigate ET-1 plasma concentration in patients with mild-to-moderate essential hypertension and its interrelationship with catecholamines, neuropeptide Y and atrial natriuretic peptide (ANP).
