The pulmonary blood volume variation is higher in patients with heart failure compared to healthy controls

چکیده
Background In left ventricular heart failure, blood will congest backwards to the pulmonary circulation and result in an increased pulmonary vascular resistance. If the increase in pressure result in impaired gas exchange due to pulmonary oedema, the pulmonary blood will redistribute to better ventilated areas in order to maintain adequate gas exchange[1]. This might affect the pulsatility of the pulmonary blood flow which can be quantified by measuring the pulmonary blood volume variation (PBVV)[2]. Therefore, the aim of this study was to investigate if PBVV in patients with heart failure differed from healthy controls.

Background and Aim: Pulmonary hypertension is an independent risk factor in COPD. Echocardiographic evaluation is important for determination of prognosis in these patients. Cardiovascular manifestations in COPD include increased arterial stiffness, ischemic heart disease, chronic heart failure and cor-pulmonale. Some studies suggest that right ventricular (RV) dysfunction occurs in early sta...

BACKGROUND Pulmonary hypertension is caused by a heterogenous group of disorders with diverse pathophysiological mechanisms, with ultimate structural changes in the pulmonary vascular bed. Platelet activation plays an important role in the development of pulmonary arterial hypertension, while it is unknown whether it contributes to pathogenesis in other conditions. We aimed to investigate plate...

Background Although the left ventricle is the major site of BNP secretion in response to cardiac pressure or volume overload, the myocytes of both atria and ventricles secrete B- type natriuretic peptide (BNP). This study aimed to assess and compare the plasma levels of BNP in common pediatric cardiac diseases to clarify its pathophysiological role and evaluate its po...
