Multipolar maps in patients with postinfarction heart failure.

Purpose: The aim of this study was to assess the changes in body surface maps in patients with postinfarction heart failure (PIHF).

Materials And Methods: Body surface mapping was performed in 22 patients with PIHF and 20 age-matched healthy controls, using a 64-electrode vest. A card index was made for every patient and person of the control group, containing isopotential and isointegral maps.

[New pathophysiological concepts in pulmonary hypertension in COPD].

Pulmonary hypertension (PH) is a frequent complication of chronic obstructive pulmonary disease (COPD) highly correlated with the prognostic disease. In advanced stages, pulmonary vascular remodeling together with the hypoxia induced vasoconstriction represents the main factors responsible for PH. However, recent studies have demonstrated that structural anomalies of pulmonary arteries may be already evident in the initial stages of COPD, which usually lack hypoxemia.
