A study shows that many heart patients are not able to tell the difference between angina pain and a heart attack and tend to delay in calling an ambulance when experience chest pain.
In a BMJ "Editorial : Advising patients on dealing with acute chest pain", 335;3-4 ( 6 July 2007), heart experts warn that high-risk patients with heart disease are confused by the varying advice given by different sources on how to use the GTN sprays to relieve their symptoms and when they should call an ambulance. Some high-risk patients may be waiting too long before seeking help as one research showed the average time from onset of symptoms to cardiac rest is 10 minutes.
The authors recommend that high-risk patients need clear guidance on how to distinguish between the symptoms of chest pain and heart attack and wait 5 minutes before calling an ambulance.
