LESS SERIOUS CAUSES
Costochondral Pain
Chest Wall Pain
Esophageal Pain
Emotional Disorders
OTHER CAUSES
(1) Cervical disk disease.
(2) Osteoarthritis of cervical or thoracic
spine
(3) Abdominal disorders: peptic ulcer,
hiatus hernia, pancreatitis, biliary colic
(4) Tracheobronchitis, pneumonia
(5) Diseases of the breast (inflammation,
tumor)
(6) Intercostal neuritis (herpes zoster)
Examination findings
Examination is often normal but may reveal risk factors
such as xanthelasma indicating hyperlipidaemia.
Signs of anaemia or thyrotoxicosis may be identified, both
of which can exacerbate angina.
Cardiovascular examination may reveal left ventricular
dysfunction or cardiac murmurs in patients with aortic
valve disease and hypertrophic cardiomyopathy.
Evidence of arterial disease, such as bruits and loss of
peripheral pulses, may also be observed.
History and examination may reveal pallor or sweating
caused by accompanying autonomic disturbance,
arrhythmia, hypotension or heart failure.
Investigations
Initial triage is by 12-lead ECG and serum troponin I or
T.
Acute coronary syndrome is suggested by ST elevation
or depression and elevated troponin I or T, indicating
myocardial damage.
If the diagnosis remains unclear, repeat ECGs are
useful, particularly if recorded during pain.
If baseline plasma troponin is normal, repeat
measurements should be made 6 to 12 hours after the
onset of symptoms or after admission.
New ECG changes or elevated troponin confirm the
diagnosis of an acute coronary syndrome.
If the pain settles, there are no new ECG changes and
troponin remains normal, the patient can be
discharged, but further investigations may still be
indicated.
Further Investigations
Blood count, fasting glucose, lipids,
thyroid function tests are the basic
investigations.
An exercise ECG may identify high-risk
patients requiring further investigation, but
false-negative and false-positive results
can occur.
Patients with chest pain suggestive of
coronary disease but with a normal
exercise ECG should undergo CT
coronary angiography.
If a murmur is found, echocardiography
should be performed to exclude valve
disease or hypertrophic cardiomyopathy
