PARIS & SAN FRANCISCO--()--Cardiologs Technologies announced today that it has raised $6.4 million in a Series A financing with a syndicate of life science and technology investors (Idinvest, ISAI, Kurma Partners, Partech Ventures) and with continued support and participation from current investor Bpifrance seed fund (F3A). This round brings total funding of Cardiologs to $10 million. Proceeds will be dedicated to fast-forward commercialization of the Cardiologs ECG Analysis Platform in the United States and Europe.

“Ambulatory ECG analysis and reporting is a labor-intensive process that can result in delays for arrhythmia detection and increased costs,” said Yann Fleureau, co-founder and CEO of Cardiologs Technologies. “Our Cardiologs team has trained a neural network using more than 500,000 recordings, and this training dataset keeps growing,” said Fleureau. “The result is that Cardiologs is designed to recognize patterns in a cardiac signal for fast and precise analysis of heart diseases in a similar intuitive manner as expert cardiologists,” said Fleureau.

In July 2017, Cardiologs announced FDA clearance of its Cardiologs ECG Analysis Platform, an ECG- analysis web solution powered by Artificial Intelligence (AI). Cardiologs assists physicians in screening for 10 arrhythmias including Atrial Fibrillation (AFib) using ambulatory ECG monitoring recordings.

Why solving Ambulatory ECG analysis is important

  • Atrial Fibrillation (AFib) is the most common human arrhythmia, affecting about 33 million patients worldwide. AFib is a growing problem in cardiovascular disease and is associated with an increased risk of severe stroke, heart failure, and death.1
  • AFib is often asymptomatic and silent with stroke as the first manifestation. Recent stroke registries indicate that AFib is associated with one-third of all ischemic strokes.
  • The Ambulatory ECG records continuously the electrical activity of the heart (ECG) up to a few weeks. It is the gold standard examination to detect AFib and other arrhythmias (for example bradycardia, which is a cause of syncope).
  • The Ambulatory ECG analysis aims to detect the episodes of arrhythmia. Only a few minutes of arrhythmia can occur during a whole week of recording, making the process labor- intensive.
  • Solving ambulatory ECG analysis results in significant cost-savings for the healthcare system, earlier diagnostic and decreased risk of stroke for the patient, time savings and increased performance for the healthcare professional.

How Cardiologs works

  • A cardiologist recovers a digital ECG from any compatible ECG device — such as a Holter monitor, smartwatch, ECG patch or even a connected t-shirt—then uploads it to the Cardiologs cloud and is able to immediately leverage our technology to identify relevant events.
  • It is especially powerful for long-term recordings that require today a very laborious manual analysis process.
  • ECG monitoring product and service companies can also benefit from Cardiologs in just three lines of code via the company’s web API.

Availability in Europe and the United States

The Cardiologs solution is CE-marked and has been approved to detect up to 100 cardiac abnormalities in Europe. Currently, the detection of 10 significant arrhythmias is available in the United States, which covers most clinical cases of ambulatory ECG monitoring. The company plans to further extend its AI capacity beyond ECG diagnostics claims.

"Cardiologs is the perfect example of applying state-of-the-art machine learning techniques to help professionals work much faster and more accurately. And in this case, it can save a lot of lives," said Benoist Grossmann, Managing Partner at Idinvest.

J-David Chamboredon, CEO of ISAI, added: "Cardiologs' fundamentals are outstanding. Its ability to combine deep learning and medical expertise can usher a new era for cardiology."

"Cardiologs has assembled a world-class team with a unique combination of mathematical and engineering skills,” said Reza Malekzadeh, General Partner at Partech Ventures. “It is great to see them out to solve a global problem with a solution that will bring better healthcare to a greater number at a more affordable cost."

Scientific Validation of Cardiologs

When defining the reliability of diagnosing AFib and other arrhythmias, the term Positive Predictive Value (PPV) refers to the percentage of true positive cases among total cases detected. Conventional “state-of- the-art” PPV for detecting AFib is less than 59%[1]. The PPV for Cardiologs’ detection of AFib was 91%[2] included in the cleared FDA submission. In addition, also as included in the cleared FDA submission, Cardiologs’ sensitivity for detecting AFib was reported to be 97%[3] (the percentage of positive cases truly identified) and was superior to “state-of-the-art” conventional methods of detecting AFib and other arrhythmias. Cardiologs’ study results have been published in the European Journal of Preventive Cardiology (2016, Vol. 23(2S 41-55). The study’s investigators concluded: “This (Cardiologs) method may be more reliable and accurate than previous methods in the diagnosis of AFib on long-duration ambulatory ECG and other monitoring devices.”
