BACKGROUND Systemic sclerosis (SSc) is an autoimmune chronic disease characterized by diffuse fibrosis involving several organs, including heart. Aim of our study was to analyze left ventricular (LV) myocardial deformation, by use of 2D strain, in asymptomatic SSc patients with normal LV ejection fraction. METHODS We enrolled 29 SSc patients (28 female, 65±4 years) and 30 controls (23 female,...

BACKGROUND In patients with cancer receiving potentially cardio-toxic chemotherapy, measurements of left ventricular (LV) circumferential or longitudinal strain are often used clinically to identify myocardial dysfunction. Using a new software algorithm, we sought to determine in individuals receiving treatment for cancer the association between automated assessments of LV mean mid-wall circumf...

AIM To analyze the very early changes of diastolic LV function during and after chemotherapy (CT) in patients with newly diagnosed acute leukemia. METHODS 26 patients with acute leukemia have been studied. The cardiac echo evaluation was performed at the baseline (before CT), after the first CT (mean cumulative anthracyclines dose 136.3-/+28.3 mg m(-2)), after the last CT (mean cumulative ant...

BACKGROUND AND OBJECTIVES Cardiovascular complications are the leading cause of morbidity and mortality in childhood cancer survivors. Hematopoietic stem cell transplantation (HSCT) is a curable therapy for pediatric cancer. However, changes in cardiac function in children after HSCT are not well known. We assessed left ventricular (LV) function in children after HSCT using speckle tracking ech...

Contractile dysfunction is underdiagnosed in early stages of diabetic cardiomyopathy. We evaluated the potential of circulating long non-coding RNAs (lncRNAs) as biomarkers of subclinical cardiac abnormalities in type 2 diabetes. Forty-eight men with well-controlled type 2 diabetes and 12 healthy age-matched volunteers were enrolled in the study. Left ventricular (LV) parameters were measured b...

BACKGROUND Subclinical myocardial involvement is common in systemic sclerosis (SSc) and associated with poor prognosis. Early detection, particularly during follow-up, is important. Two-dimensional speckle tracking echocardiography (STE) has already been shown to detect early left ventricular systolic impairment in SSc patients with advanced disease. The aim of this study was to assess the abil...

Detectable low circulating level of cardiac troponin T (cTnT) may reflect subclinical myocardial injury. We tested the hypothesis that circulating levels of hs-cTnT are altered in adults with repaired tetralogy of Fallot (TOF) and associated with ventricular volume load and function. Eighty-eight TOF patients and 48 controls were studied. Plasma hs-cTnT levels were determined using a highly sen...

Sudden cardiac death (SCD) is a common cause of mortality, with an annual incidence in the United States ranging from 180 000 to 450 000 cases annually.1 Given the frequency and gravity of SCD, there has been considerable effort directed toward decreasing the burden of SCD.2 Most of these efforts have focused on those at highest risk for SCD: (1) patients with heart failure (HF), specifically t...

Aortic stenosis (AS) is the most common primary valve disorder in the elderly with an increasing prevalence. It is increasingly clear that it is also a disease of the left ventricle (LV) rather than purely the aortic valve. The transition from left ventricular hypertrophy to fibrosis results in the eventual adverse effects on systolic and diastolic function. Appropriate selection of patients fo...

Nonhuman primates are commonly used in cardiovascular research. Increased arterial stiffness is a marker of subclinical atherosclerosis and higher CV risk. We determined the augmentation index (AI) using applanation tonometry in 61 healthy monkeys (59% female, age 1-25 years). Technically adequate studies were obtained in all subjects and required 1.5 +/- 1.3 minutes. The brachial artery provid...
