<h3>BACKGROUND:</h3> Patients with COPD face an increased risk of cardiovascular disease and cardiac mortality. Carotid femoral pulse wave velocity (cf-PWV) is a validated measure arterial stiffness, well recognized predictor adverse outcomes, offers higher predictive value than classical factors. We investigated the association between stiffness using cf-PWV as noninvasive technique. <h3>METHODS:</h3> This clinical study was prospective, observational, cross-sectional. Sixty-two subjects...

An early prediction of prognosis in pulmonary embolism (PE) is a crucial clinical entity. The aim the study to investigate whether growth differentiation factor-15 (GDF-15) or N-terminal pro-brain natriuretic peptide levels (NT-proBNP) can better predict 30 day overall mortality patients with normotensive acute PE.Patients high probability PE, low/intermediate and positive D-dimer test, underwent contrast-enhanced computed tomography ventilation/perfusion lung scan. Simplified severity...

Genetic and acquired thrombophilic risk factors may play role on developing venous thromboembolism (VTE). In many cases of pulmonary (PE) it can not be defined any explicit factor. this study we aimed to identify the plasma viscosity level PE.

Pulmonary sequestration is an embryonic, cystic lung tissue that supplied by systemic blood circulation. It a nonfunctional parenchyma unconnected to normal tracheobronchial system. In cases of pulmonary sequestration, surgical interventions should be performed in order prevent possible complications such as massive hemoptysis and infections. Preoperative imaging treatment planning done carefully. We present uncommon case recurrent caused intralobar located the left lower lobe.
