DEVELOPMENT OF AN INTERNET OF THINGS–BASED SYSTEM FOR REMOTE MONITORING OF PATIENTS WITH CARDIOVASCULAR DISEASES IN ANGOLA

Abstract

This study presents the development of an Internet of Things (IoT)-based system for the remote monitoring of patients with cardiovascular diseases in Angola, a context characterized by the increasing incidence of these conditions and limitations in healthcare infrastructure and medical personnel. The proposed system integrates wearable devices capable of collecting vital data such as blood pressure, heart rate, and blood oxygen levels, transmitting them automatically to a cloud platform accessible through a mobile application. This integration enables real-time monitoring of patients’ health status, the generation of automatic alerts in case of abnormal values, and the production of clinical reports that support medical decision-making. The system was developed using an iterative prototyping approach, allowing continuous adjustments according to user needs. A functional prototype was implemented and preliminary tests were conducted to evaluate the system’s performance and usability. The results indicate satisfactory efficiency levels, although challenges related to connectivity, energy autonomy, and comfort in continuous device usage were identified. The findings suggest that the proposed solution has significant potential to support remote patient monitoring and strengthen digital health strategies in Angola.
