Task by task
We graded 25 tasks, listed here from most to least exposed. AI can do 2 of them today, speeds up 12 and leaves 11 to people.
| Task | AI exposure |
|---|---|
| Calculate valve areas from blood flow velocity measurements. Valve area formulas already built into echo software. | 80% AI can do it |
| Obtain and record patient information, including patient identification, medical history, and examination results. AI scribes capture history and exam notes; clinician verifies accuracy. | 75% AI can do it |
| Compare measurements of heart wall thickness and chamber sizes to standards to identify abnormalities, using the results of an echocardiogram. AI measurement tools flag abnormal chamber sizes; physician confirms findings. | 62% AI helps |
| Answer questions that patients have about their health and well-being. AI answers routine questions; clinician reviews sensitive or complex ones. | 58% AI helps |
| Diagnose medical conditions of patients, using records, reports, test results, or examination information. AI handles chart and report synthesis; clinician makes final diagnosis. | 58% AI helps |
| Advise patients and community members concerning diet, activity, hygiene, or disease prevention. Education content drafted by AI; counseling stays with clinician. | 50% AI helps |
| Prescribe heart medication to treat or prevent heart problems. AI checks interactions and dosing; physician decides and signs prescriptions. | 50% AI helps |
| Order medical tests, such as echocardiograms, electrocardiograms, and angiograms. AI suggests appropriate tests from history; physician signs the order. | 48% AI helps |
| Conduct research to develop or test medications, treatments, or procedures that prevent or control disease or injury. AI speeds literature review and trial data analysis; scientists design studies. | 42% AI helps |
| Monitor patients' conditions and progress, and reevaluate treatments, as necessary. Remote monitoring and EHR alerts flag changes; clinician reassesses treatment. | 42% AI helps |

| Task | AI exposure |
|---|---|
| Design and explain treatment plans, based on patient information such as medical history, reports, and examination results. AI can draft treatment options; physician weighs risks and patient values. | 40% AI helps |
| Explain procedures and discuss test results or prescribed treatments with patients. AI drafts plain language explanations; live discussion stays with clinician. | 35% AI helps |
| Recommend surgeons or surgical procedures. AI can list options; surgical referral needs clinical and team judgment. | 35% AI helps |
| Talk to other physicians about patients to create a treatment plan. Case discussions are live; AI can summarize charts beforehand. | 25% AI helps |
| Supervise or train cardiology technologists or students. Mentoring and supervision rely on in person judgment and relationships. | 18% Needs a person |
| Conduct electrocardiogram (EKG), phonocardiogram, echocardiogram, or other cardiovascular tests to record patients' cardiac activity, using specialized electronic test equipment, recording devices, or laboratory instruments. Test acquisition needs hands on the patient and probe. | 15% Needs a person |
| Diagnose cardiovascular conditions, using cardiac catheterization. Cath lab procedure is physical; AI helps only with interpretation. | 15% Needs a person |
| Conduct exercise electrocardiogram tests to monitor cardiovascular activity under stress. Treadmill stress testing needs a physically present clinician monitoring patients. | 12% Needs a person |
| Conduct tests of the pulmonary system, using a spirometer or other respiratory testing equipment. Spirometry needs in person patient coaching and equipment handling. | 12% Needs a person |
| Observe ultrasound display screen, and listen to signals to record vascular information, such as blood pressure, limb volume changes, oxygen saturation, and cerebral circulation. Doppler acquisition needs a sonographer's hands on the patient. | 12% Needs a person |
| Administer emergency cardiac care for life-threatening heart problems, such as cardiac arrest and heart attack. Live resuscitation and urgent bedside care needing physical presence. | 8% Needs a person |
| Operate diagnostic imaging equipment to produce contrast-enhanced radiographs of heart and cardiovascular system. Operating contrast imaging equipment on patients needs trained staff present. | 5% Needs a person |
| Inject contrast media into patients' blood vessels. Injecting contrast into vessels is a physical procedure. | 4% Needs a person |
| Perform minimally invasive surgical procedures, such as implanting pacemakers and defibrillators. Implanting devices requires procedural skill and physical presence in the lab. | 3% Needs a person |
| Perform vascular procedures, such as balloon angioplasty and stents. Angioplasty and stenting are manual, time critical procedures. | 3% Needs a person |

Questions about cardiologists and AI
Will AI replace cardiologists?
Partly. About 3 in 10 working hours of a cardiologist go to tasks AI can already do, mostly valve area calculations from echo measurements and chart documentation. Procedures and bedside decisions stay with people who can act on the patient in real time.
Which tasks are AI taking over for cardiologists?
Calculating valve areas from blood flow velocity, with an exposure score of 80, is already built into echo software. Recording patient history and exam findings, with an exposure score of 75, is moving to AI scribes that the clinician checks for accuracy before signing the note.
Which cardiology tasks stay human?
Implanting pacemakers and defibrillators scores 3 on exposure because it needs procedural skill and a physical presence in the lab. Balloon angioplasty and stent placement also score 3, since they are manual and time critical, and exercise stress tests score 12 because a clinician must watch the patient on the treadmill.
How can cardiologists stay valuable as AI takes on documentation?
Check every AI echo measurement and chart summary in Epic Systems or MEDITECH before it reaches a patient. Keep hands-on volume in angioplasty, stenting, and device implants, and lead the sign-off on AI-flagged chamber size findings so the final diagnosis stays with you.
