In this study we analyzed the interaction between active seniors and mobile phone use. Results were obtained from a survey. Participants were 165 active seniors enrolled in university programs for seniors, most of whom owned a mobile phone and used it for basic functions such as making calls, creating a contact list, checking the time, and sending text messages. The mobile phone did not have a social expansion function (that is, to extend their social networks) for these people; but it did provide them with social support by allowing them to keep in touch with their relatives. It also made them feel secure, free, and independent. [ABSTRACT FROM AUTHOR]

One hundred and twenty five consecutive patients discharged from a chest pain unit (group I, 32 with the diagnosis of probable ischemic heart disease and group II, 93 with the diagnosis of non-vascular pain) were prospectively followed up for one year. In group I (treadmill exercise testing were positive at a high workload in 15, negative in 9 and inconclusive in 4), one patient had non-ST elevation acute coronary event 15 days after discharge and two patients had unstable angina at 3 and 5 months. There were no events among the patients who had positive or inconclusive exercise testing. In group II (treadmill exercise testing were negative in 85 and inconclusive in 5) one patient had non-ST elevation acute coronary event at 7 months and one had unstable angina at 11 months. In conclusion, patients discharged from a chest pain unit, including those patients with positive treadmill exercise at a high workload, have a favorable mid-term outcome.
