Digital revolution
Real-time cardiac diagnostics
The COALA is ideal for user-centered studies and for collecting large amounts of ECG data and heart sounds in geographically distributed groups. COALA's market-leading performance is clinically evaluated and is based on research findings presented at several national and international research conferences.
The Coala Care portal provides web-based access to real-time patient data with abilities to interpret, annotate and download raw data for further analysis. It’s all Microsoft Azure based with secure storage in the US and Europe.
Digital revolution
A ground-breaking Swedish innovation
COALA is a unique medical innovation based on more than 10 years of R&D, with more than 20 patents and over 15 industry awards.
A device and cloud-based solution including a high-performance stethoscope, three integrated electrodes to capture diagnostic-quality ECG and smart algorithms enabling real-time analysis of data.
Ideal for patients with palpitations
Addressing the needs of modern cardiology
The COALA was used in the groundbreaking RedHeart Study by the Karolinska Institute (Stockholm, Sweden) and included nearly 1,000 women and over 280,000 ECG recordings in everyday life. The study showed an increase in quality of life in women with palpitations, because of the instant results that helped reduce symptoms, anxiety and depression.
For stroke patients
Proven efficient and feasible
In the late-breaking TEASE-trial the Coala was used to monitor cryptogenic stroke patients. The Coala was used twice daily, and when symptoms occurred, for 28 days. The monitoring detected previously undiagnosed AF in 9% of the patients, at a mean of 19.7 days after stroke. Patient compliance to the Coala monitoring protocol exceeded 90%.
The stroke patients reported very high satisfaction with the Coala per the second TEASE-publication. The Coala was reported easy to use and it increased the feel of security. The researchers concluded that Coala to be an excellent, patient-friendly device for monitoring stroke patients.
