[The strategy and process of out-hospital emergency care of acute cardiovascular events].

Objective: To study the strategy and process of out-hospital emergency care of acute cardiovascular events.

Methods: One hundred and eighty-three patients in the Second Affiliated Hospital of Baotou Medical College were prospectively studied. The patients were divided into two groups according to the different ways of out-hospital care, one group consisted of patients who received first-aid care after calling "120" (94 cases), another was self-aid group consisting of patients sent to hospital by relatives (89 cases). The proportion of persons with higher than high school education and better knowledge for emergency care of patients with heart disease in first-aid group was higher than self-aid group (50.0% vs. 29.2%, 83.0% vs. 60.7%, both P<0.05). When the patients were brought to the emergency room, they were all treated according to our standard procedure and then registered. All patients were followed up at the end of first and third month after illness.

Results: Cardiovascular events were mainly myocardial infarction (61.7%) among 183 patients. There were statistically significant differences between two groups in self-aid response time, first disposal time and out-hospital rescuing time [(32.3+/-5.6) minutes vs. (89.6+/- 8.4) minutes, (47.3+/-7.3) minutes vs. (149.8+/-13.5) minutes, (61.7+/-8.3) minutes vs. [(149.8+/- 13.5) minutes, all P<0.01], but no difference was found in in-hospital rescuing time [(29.9+/-5.3) minutes vs. (31.1+/-4.5) minutes, P>0.05]. Morbidity rate was lower in first-aid group than self-aid group in 1st and 3rd month, respectively (2.1% vs. 9.0%, 4.2% vs. 12.4%, both P<0.05).

Conclusion: Excellent emergency system and procedure can shorten initial disposal time and out-hospital rescuing time, thus improve patients' prognosis. The education level and health knowledge of patients and their relatives directly affect their mode of arriving hospital and prognosis.
