Cleerly Testing Portland Oregon

Watch why Dr. Arthur Agatston, inventor of the Coronary Calcium Score (CACS), has integrated Cleerly's CCTA analysis into his concierge medicine practice. 

As a member of Dr. Retzler's concierge Age Management practice you too will have access to this life-saving technology.


Cleerly® is a digital healthcare company transforming the way clinicians approach the treatment of heart disease. Cleerly's clinically-proven, AI-based digital care platform works with coronary computed tomography angiography (CCTA) imaging to help us precisely identify and define atherosclerosis earlier, so we can provide personalized, life-saving treatment plans for all patients throughout your care continuum.

Cleerly® measures atherosclerosis - plaque build-up in the heart's arteries - not indirect markers such as risk factors and symptoms of disease. Cleerly's AI-enabled digital care pathway offers simpler, faster, more accurate heart disease evaluation and reporting that's tailored to each individual for improved clinical outdcomes.

What Calcium Scoring Can’t Tell You About Coronary Artery Disease Risk

While CACS identifies the presence of calcified plaque, Cleerly's AI-enabled CCTA analysis provides comprehensive visualization of both calcified and non-calcified coronary plaque as well as the severity of stenosis — offering the ability to stage and track heart disease progression using powerful artificial intelligence. AI-enabled CCTA evolves the CACS approach for a new, higher standard of heart care.

Precision Heart Health

Cleerly® testing empowers Dr. Retzler to go beyond traditional measures of heart disease by analyzing, characterizing, and quantifying types of plaque, so she can more accurately determine your risk of heart attack and develop a treatment plan to improve heart health - no matter where you are on the heart disease continuum.

Early Detection of Heart Disease

For over 50 years, cardiology has really been “sickcare,” with a focus on symptoms of heart disease rather than the disease itself, atherosclerosis. Over 10 years of clinical trial data have revealed that it's the type of atherosclerotic plaque buildup that matters most. Instead of waiting for reduced blood flow or blockages, it's time to get ahead of the problem, evaluate the underlying disease, and treat it with precision.

A New Approach

Cleerly® testing provides you with a better understanding of heart disease and your personal risk factors, giving you the insights needed to make better choices for your heart health while guiding you with a personalized, more effective treatment plan and the ability for Dr. Retzler to track your disease over time with Cleerly's Track Your Plaque™ feature.

With easy-to-understand language and straightforward educational resources, Cleerly's platform provides you with the right information at the right time to adhere to your treatment plan.

Reasons to Believe

  • 50% of people who suffer a heart attack will do so without experiencing symptoms.1
  • 70% of heart attack victims are considered low risk by traditional methods of assessing heart disease.2
  • 75% of lesions that are responsible for heart attacks only cause mild narrowing of the arteries and are missed by conventional stress testing.3

"Imagine a world where there are no sudden deaths from heart attacks because people have warnings, a chance to change their course, and a chance at a healthy life.

That's our vision — a world without heart attacks."
