Introduction
Functional capacity is an established determinant of hospital admissions, quality of life, and mortality in routine clinical use in heart failure. The state of pulmonary vascular bed in heart failure is another predictor of the patients’ prognosis and outcome. Nonetheless, the role of increased pulmonary artery stiffness (PAS) has not been studied in LV dysfunction. We investigated the relationship between PAS and functional capacity in heart failure patients.
Material and Methods
We investigated patients with the diagnosis of congestive heart failure. Patients with chronic obstructive pulmonary disease, systemic inflammatory disease, mitral valve replacement, connective tissue disease, and primary pulmonary hypertension were excluded. Pulmonary artery stiffness (PAS) was echocardiographically measured by the division of maximal frequency shift (MFS) to acceleration time (PAcT) of the pulmonary artery flow trace: PAS (kHz/sec)= MFS/PAcT
