Structuring Condition and Prognosis Reports for Ischaemic Heart Disease

In complex clinical negligence and personal injury litigation, the condition and prognosis report serves as the essential bridge between cardiac findings and the quantification of future loss. For ischaemic heart disease (IHD) claims, the expert must translate physiological states, symptom burden, and therapeutic requirements into a structured, evidence-based format that satisfies the requirements of CPR Part 35. Ensuring the expert addresses the nuances of cardiac prognosis is necessary to provide the court with reliable evidence for settlement or trial.

The Clinical Framework of IHD Prognosis

A cardiac report should assess the claimant’s prognosis as a multi-factorial issue rather than a static snapshot. Experts are expected to consider relevant clinical benchmarks including:

• Functional Capacity: Documentation of symptoms often utilises the New York Heart Association (NYHA) classification, which may be supported by objective clinical data such as exercise tolerance tests or cardiopulmonary exercise testing (CPET) where clinically indicated.
• Left Ventricular Function: Assessment of Left Ventricular Ejection Fraction (LVEF) is a standard element of cardiac evaluation. Experts should differentiate between transient functional changes—such as those arising from myocardial stunning or recent revascularisation—and permanent impairments in ventricular function.
• Imaging and Diagnostics: Prognosis in chronic IHD often involves findings from coronary angiography, fractional flow reserve (FFR), or stress perfusion imaging. Experts are expected to distinguish between stable clinical presentations and higher-risk profiles indicative of future acute coronary syndrome (ACS).
• Comorbidities: The interaction between IHD and systemic conditions, including diabetes mellitus, chronic kidney disease, or peripheral vascular disease, remains a key factor in determining the clinical trajectory.

Legal Relevance and the Role of the Expert

Under CPR Part 35.3, the expert’s overriding duty is to the court, taking precedence over any duty to the instructing party. The expert must assist the court by identifying the impact of the index event on the claimant’s life expectancy, functional capacity, and future care needs.

A recurring difficulty in litigation is the failure to link cardiac findings to legal concepts of causation. For instance, in cases involving allegations of delayed diagnosis of myocardial infarction, the report must differentiate between the clinical consequences of the index event and the natural progression of underlying coronary disease. This distinction is vital for accurate apportionment, particularly when considering whether the index event resulted in a material contribution to the current cardiac state or if the outcome is attributable to the underlying disease process.

Common Pitfalls in Cardiac Reporting

Solicitors should be aware of reports that provide a generic prognosis without sufficient clinical grounding. Common evidentiary issues include:

• Lack of Longitudinal Data: Reliance on current presentation alone, without reference to historical ECGs, previous angiograms, or long-term medication history, may reduce the weight of the expert’s opinion.
• Regulatory Standards: Where fitness to drive is a material issue in the claim, the expert should have regard to current DVLA cardiovascular standards, avoiding reliance on general clinical impressions.
• Statistical vs. Clinical Prognosis: Experts should clearly distinguish between documented clinical decline and the statistical probability of future cardiac events. The application of mortality scores—such as GRACE or TIMI—should be balanced against the specific clinical facts of the individual case, as generic statistical reliance may be open to challenge under the Bolam/Bolitho framework.

Procedural Requirements

Communication between the legal team and the expert is governed by the CPR. Under CPR 35.10, the report must identify the documents reviewed and the substance of the instructions provided.

• Clarification of Evidence: Where ambiguity exists, CPR 35.6 allows for written questions to be directed to the expert. These should be focused on clarifying the medical evidence or reasoning within the report.
• Single Joint Experts: When the court directs that expert evidence be given by a single joint expert (SJE) under CPR 35.7, the instructions should be drafted in accordance with CPR 35.8. An SJE is intended to provide an impartial assessment for the benefit of the court and does not engage in a joint statement process with another expert.
• Joint Statements: Where two or more experts are instructed, the court may direct a discussion under CPR 35.12 to identify areas of agreement and disagreement. The expert’s role in a joint statement is to clarify the clinical reasoning that prevents consensus, which assists the court in weighing the respective evidence.

When selecting a consultant cardiologist, it is important to ensure they possess current clinical experience in the specific subspecialty area relevant to the claim, such as interventional cardiology or heart failure management, to ensure the evidence provided is both current and clinically robust.
