An innovative and true e-health service in collaboration with caregivers. Coala Atlas is created. Coala Life is awarded additional patents.


Major Swedish studies confirm that preventative ECG screening leads to both earlier and more frequent detection of atrial fibrillation.


Coala Life AB is founded as a commercialization entity of the previous Cometech and R&D projects.


Coala research is initiated by Swedish entrepreneurs and physicians with the goal of developing wireless systems for digital monitoring and diagnosing of the heart. In 2007, the first generation Coala technology platform is developed and the first patent is approved. In 2013, Coala reaches a technological breakthrough. The fourth generation's new digital technology platform provides a completely new way of screening patients by digitizing heart sounds, simultaneously taking an ECG on the chest and analysing the data in the cloud.


The European Society for Cardiology (ESC) and the American Heart Association (AHA) publish the first, joint, international guidelines that recommend ECG monitoring to detect and diagnose atrial fibrillation.


A key publication included in the comprehensive Framingham study, confirms that atrial fibrillation increases the risk of stroke considerably.


The Dutch physiologist Willem Einthoven develops the first real equipment for recording ECG signals. A solution that weighed approximately 270 kg and required five people to conduct the examination.

1821 The analogue stethoscope is invented by the French physician Rene Laennec. Today, there are over 25 million units on the market.

Heart Diseases

One of the greatest health problems of our time

Cardiovascular diseases are some of the most common causes of death in the world. More people die from cardiovascular diseases then from AIDS and all forms of cancer combined. In Sweden, four out of ten Swedes die of heart diseases. Many heart diseases can be detected and appropriately treated through preventive screening and diagnostics, including auscultation (listening to the heart) and ECG. 

Atrial fibrillation, the silent killer

Atrial fibrillation (AFIB) is one of the most prevalent cardiovascular diseases. More than 30 million people are affected, which makes the disease one of the most common forms of heart disease in the world. In Sweden alone, more than 300,000 people are affected.

The problem is that many people do not know that they have a heart disease. If proper treatment is not provided, the risk of dying prematurely is twice as high. A person with AFIB runs five times the risk of suffering a stroke and three times the risk of heart failure. In addition, the risk increases with age. One of four people over the age of 40 are at risk of suffering from AFIB.

Among people over 75 years of age, AFIB can be considered a public health disease. Examining and detecting the symptoms early is key to avoiding more serious consequences. AFIB is detected using an ECG and typically treated with medication and cardioversion.

AFIB is detected most easily with an ECG, but since the fibrillation can occur irregularly, regular screening is often preferred. However this requires access to ECG equipment that can be carried or used regularly over a longer period of time. According to the recommendations from the Swedish Board of Health and Welfare (2015), caregivers should offer treatment by using blood thinning medications for all forms of atrial fibrillation. The estimate is that this will prevent 27,000 cases of stroke over the next 20 years. A further estimate is that 30,000 new individuals will be diagnosed with atrial fibrillation each year. In Sweden less than 50% of the patients with atrial fibrillation currently receive treatment using blood clot inhibitors. Lack of treatment is particularly common in terms of women and people over 80 years of age.

Cost simulations (Davidson et al) indicate that with the new blood-thinning medications, Swedish helathcare costs will increase (SEK 158 million over 20 years), while society saves large resources (SEK 3.352 billion), primarily through reduced costs of stroke care.

The assumption is that more widespread screening, and therefore more efficient diagnosis, can prevent approximately 27,000 cases of stroke, which will result in 57,000 additional years of life, with improved lifequality. The Swedish Dental and Pharmaceutical Benefits Agency (TLV) has completed an analysis of the costs of performing mobile screening from a lifespan perspective and the conclusion is that the cost is low.

In a study published in the European Journal of Health Economics 2011, the total costs for atrial fibrillation in Swedish society is estimated at SEK 6.6 billion in 2007. Of this total, SEK 5.8 billion is related to direct costs such as hospitalizations, transportation, doctors visits, pharmaceuticals and the treatment of complications. A large part of the cost comes from serious, subsequent diseases caused by atrial fibrillation.


National screening is expected to lead to both earlier and more detection of atrial fibrillation.

In June 2015 The Swedish National Board of Health and Welfare was commissioned by the government to investigate and implement a national screening program for atrial fibrillation. The study was conducted in collaboration with the Swedish Council on Medical and Social Assessment (SBU) and the Dental and Pharmaceutical Benefits Agency (TLV).The final report is to be be submitted to the Swedish government (Ministry of Health and Social Welfare) by 2017.

More efficient care processes are needed

A common problem for patients with atrial fibrillation is that they are at risk of facing long queues for care when they are looking for help at a hospital and may not always get the expert help they need. Many times, patients with atrial fibrillation are just treated for their temporary discomfort. An electrical conversion is performed, which briefly means that the patient receives an electric shock to restore balance to the heart rate, however there is a risk of delaying the decision of the actual problem and not creating a long-term treatment plan.

These poor treatment processes can affect both patients as well as society. The fact that many people are forced to drive to and from the hospital while fibrillation attacks are occurring, is cumbersome for the individual and results in large socio-economic expenses. Over the past 20 years, in-patient care as a result of atrial fibrillation has increased by 60%, and the cost for atrial fibrillation will likely increase, due to the increasing percentage of elderly persons in the population.

ECG does not detect all heart diseases

The stethoscope is used by more than 15 million physicians each day to listen to the heart. It is an easy and quick way to conduct an initial, subjective examination of the patient. The physician looks for murmurs, a medical term for the sounds that can be heard when swirls are formed in the blood that streams through the heart. Murmurs in the heart may be normal in healthy people (so-called physiological murmurs), but they can also be caused by problems and diseases with the heart valves, so-called valvular heart diseases. Murmurs are

normally not visible on an ECG. Valvular heart diseases can be congenital or acquired. In Sweden, age-related calcification of the heart valves is the most common cause for valve problems. Valvular diseases can consist of constrictions (stenosis) or leakage (insufficiency) which means that the valve does not close properly.

Aortic stenosis (constriction of the aortic valve) is the most common valvular disease in the industrialized world. Roughly two percent of those over 65 years of age, and five percent of everyone over 80 years of age are affected. The disease is often detected in connection with the physician listening to the heart using a stethoscope.

Valvular diseases can also lead to congestive heart failure. It is the most common cause of hospitalization in Sweden, resulting in major expenses. Roughly 200,000 Swedes suffer from heart failure, and among people over 80 years of age, up to ten percent have symptoms of congestive heart failure.

Many patients today have a poor understanding of their disease, which results in increased hospital readmissions.. Through screening and more efficient methods in terms of primary care, there is the potential to determine at an early stage which patients will need to be sent for further examination. This can lead to an increased quality of life for the patient as well as a reduction in the treatment period, which leads to efficiency gains.
