Streptokinase used in general practice
Insights
Early administration of intravenous streptokinase in general practice for suspected cardiac chest pain can be safely initiated. This study shows timely treatment for myocardial infarction is feasible in a primary care setting.
Area of Science:
- Cardiology
- General Practice
- Emergency Medicine
Background:
- Chest pain is a common presenting symptom in general practice, often requiring urgent assessment for potential cardiac origin.
- Timely intervention is crucial for improving outcomes in patients experiencing myocardial infarction.
Purpose of the Study:
- To evaluate the feasibility and safety of initiating intravenous streptokinase therapy for suspected myocardial infarction in a general practice setting.
- To assess the time intervals from symptom onset to treatment initiation.
Main Methods:
- A six-month prospective study identified 43 patients with cardiac chest pain.
- Fifteen patients meeting criteria received 1.5 mega units of intravenous streptokinase.
- Treatment was initiated either at home or in a general practitioner medical ward.
Main Results:
- The median time from chest pain onset to general practitioner attendance was 60 minutes.
- The median time from pain onset to streptokinase therapy initiation was 120 minutes.
- Of 28 patients with suspected myocardial infarction, 24 were confirmed (14% over-diagnosis rate); no major adverse events occurred.
Conclusions:
- Intravenous streptokinase can be safely administered in a general practice setting for suspected myocardial infarction.
- Early treatment initiation, even with delays, showed no major complications.
- This approach may facilitate faster reperfusion therapy for acute cardiac events in primary care.
Abstract:
Over a six-month study in general practice 43 patients were identified whose presenting symptom was chest pain thought to be cardiac in origin. The median time from the onset of pain to the general practitioner attending was 60 minutes. On the basis of history, examination and initial electrocardiogram these patients were assessed as unlikely or likely to be infarcting. Of this latter group 15 fulfilled the inclusion criteria for intravenous streptokinase, four commencing treatment at home and 11 on admission to the local general practitioner medical ward. Each received 1.5 mega units over 60 minutes. The median time from the onset of pain to the start of therapy was 120 minutes. Of the 28 patients clinically suspected of having sustained a myocardial infarct 24 proved positive--an over-diagnosis rate of 14%. No major problems were encountered following streptokinase.
