BACKGROUND Interleukin (IL)-12 activity is involved in the pathogenesis of psoriasis and acute coronary syndromes. We investigated the effects of IL-12 inhibition on vascular and left ventricular (LV) function in psoriasis. METHODS AND RESULTS One hundred fifty psoriasis patients were randomized to receive an anti-IL-12/23 (ustekinumab, n=50), anti-tumor necrosis factor-a (TNF-α; etanercept, ...
Background Ventricular dysfunction in patients with a single right ventricle (SRV) or a single left ventricle (SLV) is a known risk factor for morbidity and mortality. However, the differences in SRV and SLV function remain poorly understood, with only a few studies performed1-3. In this study, we measure the strain using cardiac MRI and perform comprehensive comparison of the global and region...
BACKGROUND Regular physical activity reduces cardiovascular risk. There is concern that Marathon running might acutely damage the heart. It is unknown to what extent intensive physical endurance activity influences the cardiac mechanics at resting condition. METHODS Eighty-four amateur marathon runners (43 women and 41 men) from Berlin-Brandenburg area who had completed at least one marathon ...
Right ventricular (RV) and left ventricular (LV) dysfunction is an important determinant of poor clinical status in repaired patients with tetralogy of Fallot (TOF). The purpose of our study is to assess the impact of surgical repair on short-term RV and LV function by 2-dimensional speckle tracking echocardiography (STE).Sixty-seven patients (median age 12 months) with TOF before and 6 months ...
AIMS The contribution of the systolic function of the right ventricular (RV) outflow tract (RVOT) and of longitudinal shortening of the body of the right ventricle to global RV systolic function and exercise capacity in patients after tetralogy of Fallot (TOF) repair is unclear. Our aim was to characterize the functional role of the RVOT and to identify the most suitable method of assessing RV ...
Background A substantial fraction of patients with non ST-elevation acute coronary syndrome have an occluded culprit vessel on coronary angiography. Acute coronary occlusion often results in myocardial infarction and loss of systolic function. Identification of these patients may have considerable impact on treatment and prognosis. Aim The study aims at investigating role of 2D speckle tracki...
BACKGROUND Speckle tracking echocardiography (STE) using dedicated high-resolution ultrasound is a relatively new technique that is useful in assessing myocardial deformation in 3 myocardial layers in small animals. However, comparative studies of STE parameters acquired from murine are limited. METHODS A high-resolution rodent ultrasound machine (VSI Vevo 2100) and a clinically validated ult...
By using two-dimensional speckle tracking echocardiography, we aimed to investigate the structural and functional changes on myocardium in chronic asymptomatic alcoholics without any cardiovascular disease. Forty-one consecutive asymptomatic male alcoholics who were admitted to the outpatient alcoholism unit and 30 age matched healthy male volunteers selected as the control group were enrolled ...
