New oral anticoagulants (NOACs) are going to deeply modify the treatment of non valvular atrial fibrillation and thromboembolic disease. They are non-inferior to warfarin and trials show a similar bleeding rate (even lower for some NOACs). Nevertheless one must be cautious when dealing with patients at risk (elderly patients, frail ones, renal or liver impairment...) and practicians must be well aware of doses and contraindications. NOACs' long- term tolerance is not yet well-known. In cancer, their benefit-risk ratio compared to low molecular weight heparin remains to be determined. [less ▲]Detailed reference viewed: 30 (3 ULg)

BACKGROUND: Exercise-induced pulmonary arterial hypertension (EIPH) in systemic sclerosis (SSc) has already been observed but its determinants remain unclear. The aim of this study was to determine the incidence and the determinants of EIPH in SSc. METHODS AND RESULTS: We prospectively enrolled 63 patients with SSc (age 54+/-3years, 76% female) followed in CHU Sart-Tilman in Liege. All patients underwent graded semi-supine exercise echocardiography. Systolic pulmonary arterial pressure (sPAP) was derived from the peak velocity of the tricuspid regurgitation jet and adding the estimation of right atrial pressure, both at rest and during exercise. Resting pulmonary arterial hypertension (PH) was defined as sPAP >35mmHg and EIPH as sPAP >50mmHg during exercise. The following formulas were used: mean PAP (mPAP)=0.61xsPAP+2, left atrial pressure (LAP)=1.9+1.24xleft ventricular (LV) E/e' and pulmonary vascular resistance (PVR)=(mPAP-LAP)/LV cardiac output (CO) and slope of mPAP-LVCO relationship=changes in mPAP/changes in LVCO. Resting PH was present in 3 patients (7%) and 21 patients developed EIPH (47%). Patients with EIPH had higher resting LAP (10.3+/-2.2 versus 8.8+/-2.3mmHg; p=0.03), resting PVR (2.6+/-0.8 vs. 1.4+/-1.1Woods units; p=0.004), exercise LAP (13.3+/-2.3 vs. 9+/-1.7mmHg; p<0.0001), exercise PVR (3.6+/-0.7 vs. 2.1+/-0.9 Woods units; p=0.02) and slope of mPAP-LVCO (5.8+/-2.4 vs. 2.9+/-2.1mmHg/L/min; p<0.0001). After adjustment for age and gender, exercise LAP (beta=3.1+/-0.8; p=0.001) and exercise PVR (beta=7.9+/-1.7; p=0.0001) were independent determinants of exercise sPAP. CONCLUSION: EIPH is frequent in SSc patients and is mainly related to both increased exercise LV filling pressure and exercise PVR. [less ▲]Detailed reference viewed: 18 (3 ULg)

In case of right-to-left shunts, contrast transcranial color-Doppler (cTCD) can complete contrast transœsphageal echocardiiography with a better sensitivity. It is alson a semi-quantitative method. cTCD can also detect potential micro-emboli in unexpected cerebral areas and/or explain unexpected strokes. [less ▲]Detailed reference viewed: 38 (5 ULg)

Raynaud's phenomenon (RP) is a common vascular disorder characterized by a recurrent transient vasospasm of the fingers and toes on exposure to cold or with emotional stress. Clinical criteria are used to distinguish patients with primary or idiopathic RP (formely Raynaud's disease) from those with secondary RP (formely Raynaud's syndrome). They include history, general physical examination, capillaroscopy, test for antinuclear antibody and erythrocyte sedimentation rate. More specific exams may be needed in selective cases. Excluding RP of occupational origin, the most common cause of secondary RP is a connective tissue disease (particularly scleroderma). RP may precede other clinical symptoms by several years, but most patients with RP will not progress to systemic disease. Nevertheless, primary RP may cause significant disability. We review the pathophysiology and clinical criteria of the disorder. Unfortunately, management of PR is still empirical and largely supportive. [less ▲]Detailed reference viewed: 72 (2 ULg)

This paper intends to make an update of recent publications and guidelines for evaluation in coronary symptom-free patients undergoing vascular surgery. It emphasizes the role of preoperative clinical evaluation that should identify the most appropriate testing, and treatment strategies to optimize care of the patient and avoid unnecessary testing in this era of cost containment. Selective preoperative coronary artery disease screening and revascularization achieve excellent perioperative and late results after high-risk vascular surgery. Supplemental preoperative evaluation is discussed (exercise ECG, stress echocardiography and stress tomoscintigraphy). Asymptomatic patients with good functional capacity can undergo intermediate-risk surgery without further non-invasive testing. Conversely, further noninvasive testing is often considered for patients with poor functional capacity or moderate functional capacity but higher-risk surgery especially for patients with 2 or more intermediate risk predictors. Additional testing may be considered on an individual basis for patients without clinical markers but with poor functional capacity prior to vascular surgery, particularly those with several minor clinical risk predictors. Because of a higher prevalence of silent myocardial ischaemia in diabetes mellitus, these patients require specific care. Until further data are available, indications for myocardial revascularization in the perioperative setting are similar to those in the ACC/AHA guidelines for use of myocardial revascularization in general. General practioners, cardiologists, angiologists, vascular surgeons and anaesthesiologists should collaborate and aim to slow down the progression of atherosclerosis by giving their patients an optimum secondary cardiovascular prevention.

In 49 patients with acute myocardial infarction (AMI), the infarction topography was assessed by cross-sectional echocardiography and the location of coronary artery obstruction were correlated. A ventricular segmentation of 5 right and 16 left ventricular segments was used. The site of coronary obstruction was determined in 45 patients by coronary angiography and by necropsy in 4 patients. The exact location of the obstruction could not be found in 4 patients. The infarct related vessel was the left main artery in 1 patient, the left anterior descending artery (LAD) in 19, the left circumflex in 6 and the right coronary artery in 24. Specific segments were identified for each of the 3 coronary arteries: anteroseptal and anterior segments for LAD, right ventricular segments for the right coronary artery and basal anterolateral segment for the left circumflex. Specific segments (specificity 100%) were also identified for the principal coronary branches: basal anterior for the first anterior descending diagonal (sensitivity 71%), basal anteroseptal for the first septal perforator (83%), middle anterior for the second diagonal (100%), middle anteroseptal for the second septal (89%), basal posteroseptal for a dominant right coronary artery (89%), right ventricular anterolateral segment for the right ventricular marginal branch (83%). Echocardiographic identification of the topography of AMI can be useful in recognizing the infarct-related vessel and identifying the site of coronary artery obstruction.

To identify patients at risk of cardiac expansion during hospital stay for a first acute myocardial infarction (AMI), 41 patients underwent right-sided cardiac catheterization soon after admission and serial 2-dimensional echocardiography on days 1, 3 or 4 and between days 7 and 10. Infarct expansion was recognized by echocardiography in 11 patients (27%), most often on the second recording (day 3 or 4). Age, sex, time from onset of pain to catheterization, peak levels of creatine kinase and creatine kinase-MB isoenzyme, heart rate, mean pulmonary artery wedge pressure and left ventricular stroke work index were similar in the 2 groups. Patients in whom infarct expansion developed had a higher incidence of previous systemic hypertension (73% vs 27%, p less than 0.01) and anterior AMI (91% vs 30%, p less than 0.001) and a higher mortality rate at 1 year (73 vs 7%, p less than 0.001) than those who did not. They also had higher systolic (139 +/- 24 vs 126 +/- 18 mm Hg, p less than 0.05) and diastolic (91 +/- 14 vs 75 +/- 13 mm Hg, p less than 0.001) arterial pressures, lower stroke volume index (31 +/- 10 vs 40 +/- 10 ml/m2, p less than 0.01) and much higher systemic vascular resistance (SVR) values (1,713 +/- 380 vs 1,253 +/- 264 dynes s cm-5, p less than 0.0001). In the subgroups of patients with anterior AMI, differences were significant for diastolic arterial pressure, stroke volume index, SVR and mortality.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]Detailed reference viewed: 6 (1 ULg)
