Aetiology and Diagnosis

  • Ischaemic stroke: Infarction of tissue of the central nervous system, either symptomatic or silent (asymptomatic).
  • Transient ischaemic attack (TIA): A transient episode of neurological dysfunction caused by focal brain, spinal cord or retinal ischaemia without acute infarction which resolves completely within 24 hours. This definition is not met by chronic (non-vascular) neurological diseases or other acute neurological diseases such as metabolic or ischaemic encephalopathy resulting from general hypoxia (e.g. in the case of respiratory insufficiency, following a cardiac/circulatory arrest).
  • Haemorrhagic stroke: Neurological dysfunction caused by intra-cranial bleeding.
  • Stroke where there is uncertainty as to whether the cause was haemorrhagic or ischaemic.

Stroke severity

A stroke is described as “minor“ when the neurological symptoms can be completely reversed within 30 days or the change in the NIH Stroke Scale (see Appendix 7.3 NIH Stroke Scale) amounts to less than 3 points in comparison with the NIH Stroke Scale before the stroke. A stroke is described as “major” when a neurological deficit can still be demonstrated 30 days after the event or the NIH Stroke Scale is at least 3 points higher than prior to the stroke.

Consequences of the stroke

A stroke is described as “disabling” when more than 2 points are scored on modified Rankin Scale 90 days after the stroke. If the modified Rankin Scale score is 2 points or less 90 days after the stroke, the stroke is described as “non-disabling”.

Blood pressure after 5 minutes at rest

Systolic**

The systolic blood pressure should be measured using a blood pressure monitor that is serviced and calibrated on a regular basis. Where possible, tested devices (e.g. Omron 705 IT) should be used for epidemiological trials. Blood pressure measurement begins after the patient has been at rest for at least 5 minutes. Three readings are taken at intervals of 2 minutes; the average values of the second and third readings are entered into the CRF.

Heart rate after sitting down for 5 minutes **

Measurement of the heart rate begins after the patient has been sitting down for at least 5 minutes. This should take place after measuring the blood pressure. This should be done manually by counting the radial pulse for 30 seconds; that value multiplied by two should be entered into the CRF (beats/minute).

Further diagnoses

Dyspnoea on exertion

A patient who complains of shortness of breath with physical exertion within the last 14 days and/or at present. In cases of known heart failure, for patients in NYHA stages II-IV, dyspnoea on exertion should be coded. DZHK-SOP-K-02: Anamnesis/Clinical Diagnoses, Version: V1.0, Valid as of: 01.09.2014

Jugular venous distention

The diagnostic test for jugular venous distention is conducted with the upper body of the patient positioned at a 45° angle. The level at which the jugular vein collapses is then determined. A non-pathological finding is if the vein collapses at latest at the level of the supra-sternal notch, which normally corresponds to an 8 cm water column or 5-6 mmHg before the right atrium. If the jugular vein collapses above the supra-sternal notch, jugular venous distention must be coded. DZHK-SOP-K-02: Anamnesis/Clinical Diagnoses, Version: V1.0, Valid as of: 01.09.2014
