Dynamic changes of QTc interval and prognostic significance in takotsubo (stress) cardiomyopathy.
Prolonged QT corrected (QTc) intervals are associated with adverse cardiovascular outcomes both in healthy and high-risk populations. Our objective was to evaluate the QTc intervals during a takotsubo cardiomyopathy (TTC) episodes and their potential prognostic role. ⋯ Prolonged QTc intervals at admission during a TTC episode could be associated with a higher risk of cardiovascular rehospitalization at follow-up. Dynamic increase of QTc intervals after admission are characterized by a trend toward a better prognosis.

The prognostic significance of lung function in stable heart failure outpatients.
This study investigated the impact on all-cause mortality of airflow limitation indicative of chronic obstructive pulmonary disease or restrictive spirometry pattern (RSP) in a stable systolic heart failure population. ⋯ Presence of obstructive airflow limitation indicative of COPD or RSP were associated with increased all-cause mortality, however only independently when using the LLN definition.
