Cardiovascular injury claim
Cardiac and cardiovascular injury after a motor accident
Blunt chest force can bruise the heart, damage a valve, injure a coronary artery or produce a pericardial or rhythm problem. Severe stress can also reveal a pre-existing condition, which is not the same as the crash causing permanent cardiovascular impairment. CTP assessment requires the specific pathology, objective testing, treatment and functional class to be connected to the accident.
Accident mechanism and diagnosis
How can this injury happen in a motor accident?
Direct steering wheel or seatbelt force
Anterior chest impact can cause myocardial contusion, pericardial injury, valve damage or traumatic coronary injury.
Rapid deceleration
High-energy deceleration can injure the aorta or other major vessels and may require urgent vascular surgery.
Critical illness after a crash
Hypoxia, haemorrhage, surgery or intensive care can cause arrhythmia or cardiac strain; the record must distinguish temporary illness from permanent accident-related disease.
The injuries that may actually occur
- myocardial contusion with lasting dysfunction
- traumatic valve damage
- coronary artery dissection or ischaemic injury
- pericardial injury or constriction
- persistent accident-related arrhythmia
- aortic or major vascular trauma
Symptoms and functional effects to document
- chest pressure, palpitations or fainting
- shortness of breath or reduced exertional tolerance
- fatigue, oedema or signs of heart failure
- exercise restriction supported by cardiology findings
- ongoing medication, monitoring or surgery-related limitations
Urgent health warning
Chest pressure, fainting, severe breathlessness, new neurological signs, a racing or very slow pulse, or symptoms of major vascular injury require emergency care.
Medical evidence
What tests and findings matter?
A cardiologist or other appropriate specialist should identify the exact pathology and compare acute and follow-up tests. A temporal association with the crash is not enough if the condition is better explained by pre-existing disease.
| Test or record | What it can establish | What it cannot establish alone |
|---|---|---|
| ECG and exercise ECG | May document conduction change, ischaemia, rhythm and exertional response. | A single nonspecific ECG change does not prove permanent traumatic heart injury. |
| Echocardiography | Assesses ventricular function, valves, pericardium and structural injury; trans-oesophageal echo may be relevant in selected trauma. | Minor or pre-existing changes require causal interpretation. |
| Angiography and operative records | Document coronary, aortic or vascular injury and the exact repair or intervention. | Having angioplasty or surgery does not itself determine the impairment class. |
| Holter and specialist monitoring | Captures intermittent arrhythmia and links symptoms to rhythm. | Palpitations without recorded rhythm abnormality do not establish an arrhythmia rating. |
A separate legal classification
Threshold injury is not the same as WPI
A diagnosed injury to the heart, valve, coronary artery, pericardium or major vessel may be non-threshold. Chest pain or palpitations without a supported cardiovascular injury do not settle the classification. WPI and threshold status remain separate.
A non-threshold classification does not set a WPI percentage. Conversely, a low or zero WPI assessment does not necessarily decide the threshold-injury classification. Physical and psychiatric WPI are assessed separately and cannot be combined to determine whether impairment is greater than 10%.
Motor Accident Guidelines Part 6
How is permanent impairment assessed?
Clauses 6.233-6.237 adopt AMA4 Chapter 6. The assessor uses the table for the specific pathology, taking all relevant diagnostic tests into account. AMA4 Table 2 may be used as a referee where the pathology-specific Tables 4-12 produce doubt. Tests are not ordered by the medical assessor merely to generate a rating.
| Assessment issue | CTP method | Important limit |
|---|---|---|
| Specific cardiac pathology | Use the applicable AMA4 Chapter 6 pathology table for valvular, coronary, pericardial, arrhythmic or other supported disease. | The diagnosis must be permanent, accident-caused and supported by objective testing. |
| Doubt about functional class | AMA4 Table 2, page 171, can act as a referee under clause 6.236. | Table 2 is not a substitute for identifying the pathology and complete clinical picture. |
| Hypertensive cardiovascular disease | Use AMA4 Table 9 only with documented hypertension and the clause 6.237 treatment analysis. | Controlled hypertension may not be assessable and is rarely a direct crash injury. |
What may result in 0% or no assessable WPI?
- temporary myocardial markers or rhythm change that resolves without permanent dysfunction
- chest pain without objective cardiovascular pathology
- pre-existing disease not caused or worsened by the accident
- controlled hypertension with no supported assessable impairment under clause 6.237
What may support a higher assessment if verified?
- permanent ventricular or valvular dysfunction documented on echo
- persistent clinically significant arrhythmia recorded on monitoring
- coronary or major vascular injury with lasting functional consequence
- ongoing heart-failure signs, treatment and activity restriction supported by the applicable table
Combination and overlap rules
- Respiratory limitation is assessed under Chapter 5 where distinct from cardiac limitation.
- Peripheral vascular trauma to an extremity uses the musculoskeletal method required by clauses 6.238-6.239, not AMA4 Chapter 6 Tables 13-14.
- Pain and reduced exercise tolerance are not separately rated again when represented in the cardiovascular class.
What does not establish impairment by itself?
- palpitations without recorded arrhythmia
- one elevated troponin result
- a pre-existing murmur or atherosclerosis
- surgery or medication alone
Crash-specific examples
Blunt chest impact with transient contusion
Acute ECG or troponin change can confirm injury, but normal later function may mean no permanent cardiovascular WPI.
Traumatic valve injury requiring repair
Operative and echocardiographic evidence establish pathology; the lasting valve function, symptoms and treatment determine the applicable Chapter 6 class.

Cardiovascular assessment under NSW CTP
Assessment source: Motor Accident Guidelines Part 6, clauses 6.233-6.239; AMA4 Chapter 6 (pages 169-199), including Table 2 as a referee and the applicable pathology-specific Tables 4-12.
Threshold injury: A supported heart or vascular injury may be non-threshold; symptoms without pathology require separate classification.
What the assessor checks
- specific pathology
- all relevant diagnostic tests
- treatment and functional class
- pre-existing disease and accident causation
What does not establish the result by itself
- chest symptoms
- one nonspecific test
- procedure history alone
- pre-existing disease without evidence of accident-related change

Frequently asked questions
- Does a myocardial contusion always leave WPI?
- No. It may resolve without permanent cardiac dysfunction.
- Which cardiology tests matter?
- The Guidelines list ECG, exercise testing, echocardiography, angiography, operative records and Holter monitoring among the relevant tests.
- Can the WPI assessor order new tests just for rating?
- Clause 6.235 says diagnostic tests should not be ordered by the medical assessor for the purpose of rating impairment.
- Does heart surgery create a fixed WPI?
- No. The current permanent pathology and functional result are assessed under the applicable method.
- What if heart disease existed before the crash?
- Reliable pre-accident and post-accident evidence is needed to identify any permanent accident-caused worsening.
