The analyses of the features of pre-hospital emergent cardiac events

Objective: Systemically analysis the features of the pre hospital cardiac emergent events （PHCEE）, for further understanding the regularities of PHCEE, and for managing these emergent cardiac events much better and more on time.Methods and Results: Totally 1030 PHCEE cases be collected from 1973~1997, were analysed systemically. The most common PHCEE is: acute ischemic coronary syndrome/AICS（including AMI and unstable angina, 51.1%）, and then the cardiac arrhythmia（30. 4%）, and sudden death （8.2%）. The peak age stages of AICS are: 51~70 years old for （about 35. 6% in all CHD cases）. It should be highly noticed that: there are two peak age stages of sudden death: the first one is 51~60 year old （non retired age stage, ratio:29. 0%）, and the second is 61~75 years old （ratio:27. 0%）. In all 100 cases of sudden death, there are 74 cases who had basic cardiac diseases. In all arrhythmia cases, the paroxysmal superventricular tachycardia is most common （43.0%）. The statistic results show that the morbidity of AMI had remarkably increased in recent two decades. Conclusion: The emergent cardiac events, is now in the most needed to be treated both in hospital, but especially in pre hospital, and in all cardiac events, the AICS are most common and most important to managing. For those had the history of heart diseases, it should be highly noticed that the highly increased possibility of cardiac sudden death.
