Top hospitals for heart bypass surgery in the United States by state: A data-based review of cardiac care

Patients researching the top hospitals for heart bypass surgery in the United States by state will find that major rankings evaluate more than surgical reputation alone. Recent assessments consider survival, readmissions, discharge outcomes, patient experience, procedure volume, and the ability to manage complex cardiovascular cases. The available state-level data and national lists provide a useful comparison framework, but they do not replace an individualized discussion with a cardiac surgeon.

How the recent hospital evaluations were constructed

U.S. News evaluated nearly 500 hospitals for cardiology and related heart care in its latest state-level assessment. The evaluation covered eight cohorts: abdominal aortic aneurysm repair, aortic valve surgery, heart arrhythmia, coronary artery bypass surgery, heart attack, heart failure, pacemaker implantation, and transcatheter aortic valve replacement. An initial group of 665 hospitals was narrowed to 488 after minimum procedure-volume requirements and a transfer-pattern review designed to identify major referral centers. 1

Survival represented 45% of the U.S. News score, while the remaining score incorporated discharge-to-home rates, readmission prevention, and patient experience. This is important because a hospital recognized for broad cardiology performance is not necessarily ranked solely by CABG mortality. Castle Connolly uses a separate outcomes-driven approach that combines recent all-payer outcomes data with evaluations from its physician network across heart and vascular surgery, including CABG. 3

State-level hospitals documented in the available data

The state-by-state report identifies a leading high-performing heart hospital in each state, although the supplied publication extract provides the entries through the District of Columbia rather than reproducing the complete national table. The documented entries below therefore represent the states and scores available in the research material, not an independently completed list for every state. 1

California had the largest number of hospitals classified as high performing in cardiology care, with 20 facilities, followed by New York with 10. These counts describe high-performing cardiology facilities, not a direct count of hospitals ranked exclusively for bypass surgery. 1

Hospitals appearing near the top of national cardiac lists

A separate U.S. News based national list published by Becker's Cardiology placed NYU Langone Hospitals in New York City first with a score of 97.5, followed by NewYork-Presbyterian Hospital-Columbia and Cornell at 89.9, Mayo Clinic in Rochester at 83.3, Cedars-Sinai Medical Center at 83.1, and Mount Sinai Hospital in New York City at 82.6. Massachusetts General Hospital followed at 81.5, with Northwestern Memorial Hospital at 80.9 and Cleveland Clinic at 80.3. 6

Newsweek's 2026 cardiac-care ranking also listed Mayo Clinic Rochester first, Massachusetts General Hospital second, Cleveland Clinic third, NYU Langone Hospital-Tisch Hospital fourth, and The Johns Hopkins Hospital fifth. The listed standout services included chronic ischemic heart disease, coronary artery disease, CABG, valve surgery, angioplasty and stent placement, and heart transplantation. The breadth of these services indicates that the ranking concerns cardiac care overall, rather than a single operation. 2

Why a cardiology ranking is not a CABG-only ranking

Coronary artery bypass graft surgery is one of several procedures and conditions used in the current U.S. News cardiology evaluation. A high score may reflect performance across arrhythmia treatment, valve surgery, heart failure, heart attack care, pacemaker implantation, and catheter-based procedures in addition to bypass surgery. Consequently, a patient comparing hospitals for CABG should seek operation-specific information rather than treating a general cardiology score as a complete surgical profile. 1

Healthgrades uses a distinct specialty framework that separates cardiac care, cardiac surgery, cardiology, and coronary interventional procedures. Its 2026 state-ranking methodology analyzed Medicare inpatient data from 2022 through 2024 and included CABG surgery among mortality-based procedures. That distinction can help explain why different organizations identify different leaders: methodologies use different populations, time periods, specialties, and outcome definitions. 5

Outcome measures that add context to rankings

CMS readmission data provides another way to examine bypass results. For procedures performed between July 1, 2021, and June 30, 2024, Sarasota Memorial Hospital and Christus Mother Frances Hospital in Tyler, Texas, recorded the lowest excess readmission ratio among the hospitals listed in the supplied report, both at 0.74. Cleveland Clinic recorded 0.75, NYU Langone Hospitals 0.76, and Massachusetts General Hospital 0.79. 7

An excess readmission ratio compares a hospital's predicted readmission rate with the expected rate for hospitals treating similar patient populations. The supplied table reported 445 CABG discharges for Sarasota Memorial and 404 for Cleveland Clinic, while some facilities had too few cases to report certain figures. Readmission measures are therefore informative but should be considered with mortality, complications, case complexity, and the reliability of the underlying reporting threshold. 7

Practical limitations and questions for hospital comparison

Hospital selection involves clinical eligibility and logistical constraints, not only ranking position. The U.S. News process required minimum procedure volumes and a transfer-pattern check, while its scoring included risk-related outcome measures and patient experience. A person may also face questions concerning whether CABG is appropriate, how many grafts are anticipated, whether minimally invasive or conventional surgery is being considered, and whether the hospital routinely manages the patient's other conditions. 1

Independent oversight can add another layer of review. The Society of Thoracic Surgeons publishes public cardiac-surgery ratings based on risk-adjusted outcomes, and Premier's 50 Top Cardiovascular Hospitals program compares organizations across 21 measures, including clinical outcomes, operational efficiency, extended outcomes, and patient experience. Premier reported a 56% difference in CABG inpatient mortality index values between benchmark and peer hospitals, illustrating why outcome data can reveal distinctions that broad reputation alone may not show. 9

How to interpret the state and national lists

The most defensible interpretation is that rankings identify hospitals with strong measured performance across defined cardiac populations, not universally superior choices for every bypass patient. Mayo Clinic Rochester, NYU Langone, Cedars-Sinai, Massachusetts General, Cleveland Clinic, Johns Hopkins, and NewYork-Presbyterian appear across major national or research references, but their appearances do not establish identical CABG results or identical suitability for a particular case. 2

State-level lists are most useful for establishing a starting comparison set, especially when travel, referral patterns, and continuity of care matter. A careful review should pair the published designation with CABG-specific mortality, complications, readmissions, procedure volume, surgeon experience, risk adjustment, and patient-experience information. Rankings are evidence summaries, not guarantees, and the final decision depends on the diagnosis, operative risk, urgency, insurance eligibility, and recommendations from the treating clinical team. 5
