Left atrioventricular remodeling in the assessment of the left ventricle diastolic function in patients with heart failure: a review of the currently studied echocardiographic variables

Multiparametric echocardiographic imaging of the failing heart is now increasingly used and useful in decision making in heart failure. The reasons for this, relies on the need of different strategies of handling these patients, as differentiation of systolic or diastolic dysfunction, as well as on the gamma of approaches available, such as percutaneous and surgical revascularization, devices implantations, and valvular regurgitations and stenosis corrections. Congestive heart failure in patients with normal left ventricular diameters or preserved left ventricular ejection fraction had been pointed out recently as present in a proportion so high as 40 to 50 percent of cases of heart failure, mainly due to the epidemics in well developed countries, as is the problem of not well controlled metabolic states (such as obesity and diabetes), but also due to the real word in developing countries, as is the case of hypertension epidemics and its lack of adequate control. As a matter of public utility, the guidelines in the diagnosis and treatment of such patients will have to be cheap, available, easily reproducible, and ideally will furnish answers for the clinician questions not in a binary "black or white" manner, but with graduations, so if possible it has to be quantitative. The present paper aim to focus on the current clinical applications of tissue Doppler and of left atrial function and remodeling, and its pathophysiologic relationship with the left ventricle, as will be cleared in the documented review of echocardiography that follows, considering that the need of universal data on the syndrome of the failing heart does not mean, unfortunately, that all patients and clinicians in developing countries have at their own health facilities the same imaging tools, since they are, as a general rule, expensive

Arterial stiffness by oscillometric device and telomere lenght in juvenile idiopathic artrhitis with no cardiovascular risk factors : a cross-sectional study

Background: Advances in juvenile idiopathic arthritis (JIA) treatment is promoting free disease survival. Cardiovascular disease (CVD) may emerge as an important cause of morbidity and mortality. Pulse wave velocity (PWV), a surrogate marker of arterial stiffness, and telomere length (TL) are considered as potential predictors of CVD and its outcomes. The study aim was to assess PWV, TL in a JIA population and to test its correlation. In a cross sectional study, 24 JIA patients, 21 controls for TL and 20 controls for PWV were included. PWV was assessed by an oscillometric device. TL was assessed by qPCR. JIA activity was accessed by JADAS-27. Smoking, diabetes, obesity, renal impairment, hypertension, dyslipidemia and inflammatory diseases were excluded. Findings: Between cases and controls for TL, there was significant difference in age. No differences in gender, ethnics and bone mass index between JIA and control groups for PWV and TL. The JADAS-27 median was 8. TL was significantly reduced in JIA (0.85 ± 0.34 vs. 1. 67 ± 1.38, P = 0.025). When age adjusted by ANCOVA, the difference remained significant (P = 0,032). PWV was normal in all patients (5.1 ± 0.20 m/s vs. 4.98 ± 0.06 m/s, P = 0, 66). There was no correlation between TL, PWV or JADAS-27. Conclusion: Compared to controls, JIA with high disease activity and no CVD risk factors have shorter telomeres and normal PWV. As far as we know, this first time this correlation is being tested in rheumatic disease and in paediatrics
