Comparison of Characteristics and Outcomes of Heart Failure Patients With Preserved Versus Reduced Ejection Fraction in a Multiethnic Southeast Asian Cohort.

There are few data comparing the patient characteristics and outcomes of heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced EF (HFrEF) in Asian cohorts. We aimed to evaluate the prevalence, clinical characteristics, and 1-year outcomes of a well-defined Southeast Asian HFpEF cohort in comparison to an HFrEF cohort. We conducted a retrospective observational study of 1,978 patients discharged from Changi General Hospital, Singapore with a primary diagnosis of HF from 2009 to 2013. About 29% of discharges had HFpEF. Patients with HFpEF were more likely to be women, older age, and have a higher prevalence of hypertension. There were no significant differences in the absolute rates of 30-day outcomes between the 2 groups. The absolute rate of death at 1 year was similar in HFrEF and HFpEF at 17% and 15%, respectively (p = 0.3). After multivariate adjustment, there was no difference in the outcomes of the 2 groups. Atrial fibrillation at baseline was a predictor of death or HF hospitalization in HFpEF but not HFrEF (interaction p = 0.003). In conclusion, in this study of a Southeast Asian population with well-defined HF, we found that the clinical profile of patients with HF was similar to that in the West and 30-day and 1-year mortality and morbidity were not significantly different between cohorts.

Mobile mental health: review of the emerging field and proof of concept study.

BACKGROUND: The ubiquitous nature of mobile phones and their increasing functionality make them an ideal medium for the delivery of large-scale public health information and interventions. While mobile phones have been used to this end in behavioural and physical health settings, their role in monitoring and managing mental health is in its infancy. AIMS: The purpose of this paper is (1) to provide an overview of the field of mobile mental health and (2) by way of illustration, describe an initial proof of concept study carried out to assess the potential utility and effectiveness of a newly developed mobile phone and web-based program in the management of mild-to-moderate stress, anxiety and depression. METHODS: Over 6 weeks, participants were given access to "myCompass": an interactive self-help program, which includes real-time self-monitoring with short message service prompts and brief online modules grounded in cognitive behavioural therapy. RESULTS: Preliminary analyses found that participants' symptoms of stress, anxiety, depression and overall psychological distress were significantly reduced after using myCompass. Improvements were also found in functional impairment and self-efficacy. CONCLUSIONS: These preliminary results support the feasibility of implementing mobile phone-based interventions with the potential of improving psychological wellbeing.
