Gender differences on chest pain perception associated with acute myocardial infarction in Chinese patients: a questionnaire survey.
OBJECTIVE
To investigate gender differences in chest pain perception among Chinese patients with acute myocardial infarction.


BACKGROUND
Thrombolytic therapy is beneficial to outcomes of acute myocardial infarction if administered within 12 hours from the onset of chest pain. However, cardiac symptom interpretation may impact time of presentation to hospital. Differences in cardiac symptom reports by gender partly explain misdiagnoses and delays in treatment, particularly among women. Whether, such trends apply to Chinese patients with myocardial infarction is unknown.


METHODS
A descriptive prospective study.


METHODS
Using questionnaires, data on demographic variables, the number of patients reporting chest pain and other chest sensations at the onset of acute myocardial infarction and chest pain intensity, description, location and radiation across the chest were collected.


RESULTS
A total of 128 participants equally divided by gender were recruited. Chest pain was more prevalent among men than women (84.37% vs. 67.19%, p < 0.05). Although no statistical significance was found, Chinese men had higher mean chest pain intensity scores (7.54 SD 2.35 vs. 7.51 SD 2.25) and reported less atypical chest pain (0.00% vs. 9.3%) compared with women. Men had more upper right sided chest pain (40.74% vs. 20.93%, p = 0.038) whereas women experienced increased neck pain and pain to the upper central chest, middle central chest, upper central back, middle central back and middle right back regions.


CONCLUSIONS
Discreet gender differences in chest pain perceptions exist between Chinese men and women, with the latter group, who may be considered as a high-risk group for missed and delayed diagnosis from myocardial infarction, reporting more atypical presentations.


CONCLUSIONS
Irrespective of culture, women with myocardial infarction tend to present with atypical chest pain symptoms and therefore they should be aggressively investigated.
