    Infection is one of the most devastating outcomes of cardiovascular implantable electronic device (CIED) implantation and is related to significant morbidity and mortality. In our country, there is no evaluation about CIED infection. Therefore, our aim was to investigate clinical characteristics and outcome of patients who had infection related to CIED implantation or replacement. The study included 144 consecutive patients with CIED infection treated at 11 major hospitals in Turkey from 2005 to 2014 retrospectively. We analyzed the medical files of all patients hospitalized with the diagnosis of CIED infection. Inclusion criteria were definite infection related to CIED implantation, replacement, or revision. Generator pocket infection, with or without bacteremia, was the most common clinical presentation, followed by CIED-related endocarditis. Coagulase-negative staphylococci and Staphylococcus aureus were the leading causative agents of CIED infection. Multivariate analysis showed that infective endocarditis and ejection fraction were the strongest predictors of in-hospital mortality.

    P-wave parameters and cardiac repolarization indices: Does menopausal status matter?

    Background and purpose: Data regarding electrocardiographic characteristics of postmenopausal women are lacking. In this prospective, cross-sectional study, electrocardiographic P-wave parameters and cardiac repolarization indices of age-matched pre- and postmenopausal healthy women were compared. We hypothesized that menopausal status would have a significant effect on cardiac electrical activity and hence electrocardiography (ECG) recordings. Materials and methods: Twelve-lead ECG recordings were obtained from 125 consecutively recruited postmenopausal healthy women aged between 44 and 54 years. The control group consisted of 125 age-matched premenopausal women. P-wave parameters and cardiac repolarization indices were measured and compared with respect to menopausal status. Results: Demographic features of premenopausal and postmenopausal women were comparable. There were no significant differences between two groups regarding mean values of heart rate, maximum and minimum P-wave duration, P-wave dispersion, maximum and minimum QT interval, and QT dispersion. Mean values of QT interval obtained from lead V5 were also similar. Corrected values which were calculated according to Bazett and Fridericia formulas also did not differ between the groups. Mean values of Tpeak to Tend (TpTe) (p < 0.001) and corrected TpTe (p = 0.001) intervals obtained from lead V5 were significantly shorter in postmenopausal women when compared to those without menopause. Conclusion: Tpeak to Tend interval decreased significantly while QT intervals and P-wave parameters did not change in postmenopausal women when compared to premenopausal women. Association of these findings with changes in levels of sex steroids and their prognostic implications need to be elucidated with further studies. (C) 2012 Japanese College of Cardiology.
