Abstract Natriuretic peptides are hormones released by the heart after acute or chronic aggression. They are produced exclusively by the heart and are, therefore, specific cardiac biomarkers. Recent pivotal studies have confirmed that they are useful in the diagnostic assessment of patients with dyspnea in the emergency room, with a high predictive value in ruling out acute heart failure, and they are indicated when there are doubts in clinical examination. They are also useful as prognostic markers and in monitoring […]

Abstract Background: Heart failure with preserved ejection fraction (HFpEF), a syndrome associated to decrease functional capacity, is quite difficult to manage. Inspiratory muscle training (IMT) has been used to treat symptoms and to improve functional capacity of patients with HFpEF. Thus, we aimed to evaluate the immediate effects and after 1 h of IMT on arterial pulsatile hemodynamics and on hemodynamic indices of left ventricular filling derived from Doppler echocardiography in patients with HFpEF. Methods: Eighteen patients with HFpEF who […]
