Cardiology standard-of-care expert
Expert class library · Medical malpractice · Either side
A cardiologist who says whether a missed or delayed diagnosis of heart attack, coronary disease or arrhythmia, or the management of a cardiac procedure or medication, met the standard of care, and often whether the breach caused the patient's death. Courts routinely accept cardiologists on these questions; the fights are about the factual basis of the opinion, the link between the care and a death that came later, and whether witnesses from other specialties may opine on cardiac causes.

What this expert is retained to answer
- Does the opinion judge the defendant cardiologist on what was known at the time, rather than on records or results the defendant never had?
- How does the expert connect the care at issue to the injury or death, especially when the death came months or years later?
- Which other causes of the cardiac event or death does the expert consider, and how are they ruled out?
- Is the expert a cardiologist, or a physician from another field offering a cardiac opinion?
- Will a second cardiology expert add anything, or will the court treat the testimony as cumulative?
Methods
- ECG and troponin trend review
- ACC/AHA guideline comparison
- Risk score application
- Stress test and imaging interpretation
- Anticoagulation management review
- Cause-of-death analysis
How the testimony is attacked
- Facts the defendant did not have. An opinion defending a cardiologist must rest on what the cardiologist knew. In Armour v. Bader the Rhode Island Supreme Court held it was an abuse of discretion to let the defense cardiology expert support the defendants' care with a referring physician's records they never had.
- No reliable link to a later death. A causation opinion must explain how the care led to the outcome. In Calvin-Williams v. Greenville Clinic the Mississippi Court of Appeals affirmed striking a cardiologist's opinion that 2012 care caused a death in 2015, because it described no methodology and rested on speculation.
- Cardiac opinions from other specialties. A witness qualified in one field may not offer every opinion in the case. In Hall v. Flannery the Seventh Circuit held a neurosurgeon unqualified to opine that a heart condition was the likelier cause of death and ordered a new trial.
- Cumulative experts. Courts may limit a party to one expert per specialty. Woodson v. Go upheld limiting the plaintiff to one of two interventional cardiology experts as cumulative.
- Alternative causes without a foundation. Defense experts may describe possible causes of death if they rest on the patient's history. Wilson v. Dande admitted a defense cardiologist's testimony about stroke and embolism as possible causes, while noting that a generic list of causes not tied to the patient had no foundation.
What the public record shows
A deliberately narrow CourtListener search, cardiolog* AND "standard of care" AND (infarction OR arrhythmia OR cardiac) AND expert AND (Daubert OR "Rule 702"), returned 45 opinions filed since 2015, as of October 4, 2026; broader searches return more. 5 rulings that show how courts handle this class of testimony:
| Outcome | Case | Court | Year | Why |
|---|---|---|---|---|
| Excluded | Calvin-Williams v. Greenville Clinic, P.A.No. 2023-CA-01021-COA | Miss. Ct. App. | 2025 | The court affirmed striking a cardiologist's causation opinion and granting summary judgment, because the expert, though qualified, described no methodology connecting a cardiologist's care during a 2012 hospital stay to the patient's death three years later, and his opinion rested on speculation. |
| Excluded | Armour v. BaderNo. 2023-5-Appeal | R.I. | 2024 | The Rhode Island Supreme Court held it was an abuse of discretion to let the defense cardiology expert support the defendant cardiologists' handling of an abnormal stress test with a referring physician's records they did not have, and vacated the defense verdict, also for a jury instruction error. |
| Admitted | Wilson v. Dande2024 IL App (5th) 220552 | Ill. App. Ct. | 2024 | The appellate court upheld admitting a defense interventional cardiologist's testimony that the patient could have died of stroke, recurrent clotting or pulmonary embolism, because those possibilities rested on the patient's documented history, though it found no foundation for his generic list of causes of sudden death. |
| Excluded | Hall v. Flannery840 F.3d 922 | 7th Cir. | 2016 | The Seventh Circuit held that a neurosurgeon qualified to testify about surgery and seizures was not qualified to opine that a heart condition was the likelier cause of a patient's death, and vacated the defense verdict because the testimony likely affected the outcome. |
| Limited | Woodson v. Go166 So. 3d 231 | Fla. Dist. Ct. App. | 2015 | Affirming a defense verdict after a cardiac catheterization complication, the court upheld limiting the plaintiff to one of his two interventional cardiology experts as cumulative and receded from its earlier rule that nearly all qualified expert testimony in malpractice cases must be allowed. |

Under amended Rule 702
Since December 1, 2023, Rule 702 says expressly that the party offering an expert must show the court it is more likely than not that the testimony meets each requirement: that it rests on sufficient facts or data, uses reliable methods, and reflects a reliable application of those methods to the case. Questions about the basis of an opinion are no longer automatically matters of weight for the jury. For how the circuits have applied the amendment, see the Rule 702 tracker, which follows each court of appeals; for what that means for preparing or attacking this class of expert, see the guide on amended Rule 702.
