Monitoring Health Parameters of Elders to Support Independent Living and Improve Their Quality of Life.

Improving the well-being and quality of life of the elderly population is closely related to assisting them to effectively manage age-related conditions such as chronic illnesses and anxiety, and to maintain their independence and self-sufficiency as much as possible. This paper presents the design, architecture and implementation structure of an adaptive system for monitoring the health and well-being of the elderly. The system was designed following best practices of the Human-Centred Design approach involving representative end-users from the early stages.

Assessment of cardiac function with Doppler tissue imaging in asymptomatic HIV-infected patients.

Doppler tissue imaging (DTI) is a useful tool for the detection of subtle systolic function abnormalities related to the longitudinal contraction. We assessed left ventricular (LV) systolic function with DTI in 45 human immunodeficiency virus (HIV)-infected patients without any heart-related symptoms and in 30 healthy control subjects. Although conventional echocardiography showed no differences between groups, DTI revealed lower peak systolic velocities in group A patients when compared with group B ones (Sms: 8.

Evaluation of serial QT dispersion in patients with first non-Q-wave myocardial infarction: relation to the severity of underlying coronary artery disease.

Background: Increased QT dispersion (QTD) has been correlated with ventricular arrhythmias. Recent reports suggest that it may serve as a marker of the severity of underlying coronary artery disease (CAD).

Hypothesis: The aim of this study was to examine in-hospital changes of QTD and their possible correlation with the severity of underlying CAD in patients with first non-Q-wave myocardial infarction.

Primary stenting produces earlier and more efficient myocardial reperfusion than primary PTCA alone in patients with acute ST segment elevation MI.

Restoration of blood flow in the infarct-related artery and subsequent myocardial reperfusion are major goals of both thrombolysis and primary percutaneous interventions. Whether percutaneous transluminal coronary angioplasty (PTCA) with immediate stenting (primary stenting) produces reperfusion more rapidly than primary PTCA alone is uncertain. This study determines whether primary stenting produces earlier myocardial reperfusion than primary PTCA alone in patients with acute ST segment elevation myocardial infarction using troponin T release kinetics.

Relation of troponin T release kinetics to long-term clinical outcome in patients with acute ST segment elevation myocardial infarction treated with a percutaneous intervention.

The purpose of this study was to determine the relation of troponin T release kinetics to long-term clinical outcome in patients with an acute ST segment elevation myocardial infarction treated with a primary percutaneous intervention. One hundred and four patients with typical ischemic chest pain and > 1.5 mm ST segment elevation in > 2 contiguous leads underwent primary stenting (n = 60) or primary percutaneous transluminal coronary angioplasty (n = 44).
