What Apex Cardiology does

Apex Cardiology is a private, physician-owned outpatient cardiology practice founded in 1988 and headquartered in Inglewood, California, with a second cardiovascular CT imaging site in Torrance. The practice provides a comprehensive suite of cardiac diagnostic and interventional services, anchored by a GE LightSpeed 64-slice cardiovascular CT scanner used for non-invasive coronary angiography, calcium scoring, and structural heart assessment. The service portfolio spans echocardiography (stress, transthoracic, Doppler, transesophageal), nuclear cardiology and stress testing (treadmill, adenosine, nuclear), cardiac catheterization and invasive coronary angiography, coronary balloon angioplasty and stenting, CT peripheral angiography and peripheral angioplasty, electrophysiology and cardiac rhythm management, and in-office laboratory blood testing, supplemented by a medical weight management partnership with Enara Health.

The practice is staffed by four multi-board certified cardiologists (Dr. Vernon T. Hattori, Dr. Mason H. Weiss, Dr. Jack J. Farahi, and Dr. Robin N. Stan), a physician assistant (Eric Chew, PA-C), a nurse practitioner (Peggy Kalathil, NP), and a second physician assistant (Kevin Pape, PA-C), drawing on training at Cedars-Sinai, UCLA, Stanford, McGill, USC, and Mount Sinai. Apex Cardiology holds a Certificate of Accreditation for Cardiovascular CT Angiography and operates as a fee-for-service practice billing through contracted insurance networks including Blue Cross, Blue Shield, Aetna, Cigna, United Healthcare, Health Net, Medicare, Tricare, Pacific Care, and WGA.

Patient acquisition is sales-led and hybrid, combining physician referrals, self-referrals, community health events (MLK Celebration, El Camino College Health & Benefits Expo, Healthy Living/Healthy Business Expo), physician media appearances on KFI and KABC radio, and a website optimized for organic search. Reporting includes a 24-hour standard turnaround with same-day stat availability, and patient access is supported through a MyHealthRecord patient portal. The practice is privately held with no disclosed venture capital, private equity backing, or parent company, and no funding history, M&A activity, or executive changes are reported.

Core offering

Apex Cardiology is a multi-physician outpatient cardiology practice providing comprehensive cardiac diagnostic testing and interventional procedures, including cardiac CT imaging, echocardiography, nuclear stress testing, cardiac catheterization, angioplasty/stenting, and electrophysiology. Services are delivered across facilities in Inglewood and Torrance, California, anchored by a GE LightSpeed 64-slice CT scanner.

Product overview

Apex Cardiology offers a comprehensive suite of cardiac diagnostic and interventional services through a single unified outpatient cardiology practice. The portfolio centers on non-invasive cardiac imaging technologies including GE LightSpeed 64-slice Cardiovascular CT scanning, echocardiography (stress, transthoracic, Doppler, and transesophageal), and nuclear cardiology/nuclear stress testing. Interventional services encompass cardiac catheterization, coronary balloon angioplasty/stenting, CT peripheral angiography, and cardiac rhythm management/electrophysiology. The practice also provides stress testing across multiple modalities (treadmill, adenosine, nuclear), and has partnered with Enara Health for medical weight management services. A 64-slice CT scanner serves as the flagship diagnostic technology enabling rapid, high-resolution cardiac imaging.

Products and services

• Cardiac CT Imaging / Non-Invasive Coronary Angiogram Painless cardiac computed tomography (CT) scan using x-ray technology that produces detailed three-dimensional images of the heart, used to evaluate coronary heart disease, aortic problems, calcium buildup, heart function, pericardial disease, pulmonary vein problems, and arterial graft results. Uses iodine-based contrast dye when needed (CT angiograph). Targeted at patients and referring physicians.
• Stress Testing Comprehensive cardiac stress testing to detect heart disease by measuring heart response to physical exertion, including treadmill stress testing, echocardiogram-based stress tests, adenosine stress testing for non-exercising patients, and nuclear stress testing.
• Nuclear Cardiology / Nuclear Stress Test Nuclear cardiac imaging procedure using radioactive tracing material injection and gamma camera photography to detect coronary artery blockages and assess heart muscle damage, including rest and stress imaging phases.
• Echocardiography Cardiac ultrasound imaging using sound waves to create images of heart structure and function, including stress echocardiogram, transthoracic echocardiogram, Doppler echocardiogram, and transesophageal echocardiogram procedures.
• Cardiac Catheterization / Invasive Coronary Angiogram Hospital-based invasive procedure using catheter insertion through the femoral artery to inject x-ray dye into the heart and coronary arteries, measure cardiac pressures, and detect blockages, heart muscle damage, and valvular disease.
• Coronary Balloon Angioplasty / Stenting Interventional procedure to open severe coronary artery blockages discovered during angiography using balloon-tipped catheter inflation, followed by permanent stent placement to maintain arterial patency.
• CT Peripheral Angiography and Peripheral Angioplasty
• Cardiac Rhythm Management / Electrophysiology Testing Electrophysiology procedures using wire electrodes inserted via femoral vein to assess cardiac electrical systems, correct abnormal rhythms, and implant pacemakers, defibrillators, or perform radiofrequency ablation.
• Weight Management with Enara Health Comprehensive medical weight management partnership program with Enara Health providing sustainable weight loss through personalized science-based lifestyle changes, insurance-covered obesity care.
• Laboratory Blood Test Evaluation Full spectrum of cardiology-related laboratory tests performed in-office with most results available within 24 hours.
