Cardiovascular software firm HeartFlow said it has chosen Phil Mui as senior vice president of engineering and product.
Mui will be responsible for guiding the scalable development of the company's technology platform, HeartFlow said. The company's fractional flow reserve CT (FFR-CT) analysis software is a noninvasive technique for determining the effect of CT-detected coronary artery stenosis on blood flow and heart function.
Mui comes to HeartFlow from marketing technology and services firm Acxiom, where he led engineering, product, and marketing teams, the company said. Before joining Acxiom, he led the Google Analytics team and other projects at Google.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
