| Background:Sudden death(SD), refers to a potential disease or some kind of dysfunction causing to no obvious symptoms or healthy people happened to a suddenly unexpected death. Sudden Cardiac Death(SCD) is due to cardiac causes which trigger to unforeseen non-invasive being associated with or without natural death of the loss of sudden consciousness of cardiac primary disease, whose characteristic is a short time from onset to death and very dangerous, which is the most common cause of sudden death, accounting for about 30% of sudden death. The most common death in SCD is the sudden death of Coronary Heart Disease(CHD), of which is about 50% of SCD. SCD is the most likely to stimulate the contradiction between the two sides and lead to the two sides of further deterioration, and causes mass incidents. Meanwhile, along with the enhancement of people’s legal consciousness, popularization of forensic medicine identification and the mature of identification technology, hence, forensic scientificly identify the autopsy in order to explain the cause of deat, which has a clear and effective effect on solving these contradictions. In China, in recent years, with the improvement of people’s living standard and because of the degree of people’s mental tension gradually enhanced, the pressure of life and work gradually increased and the pace of life gradually accelerated and other factors, which cause that the morbidity and mortality of SCD in our country is rapidly increasing year by year and seriously hazard to people’s health. In the past five years, few scholars focus on the analysis of the statistical study of autopsy combining with SCD. Therefore, this study is based on the sudden death of coronary heart disease in the past three years and the complete autopsy to go on the research. Objection:1.Based on the statistical analysis of 121 cases of sudden death of coronary heart disease, in order to explore and discus the characteristics of age, gender, occupation, inducement, season and pathological changes of sudden death of CHD.2.To enrich the knowledge and content of pathological changes of coronary heart disease and so on, and provide theory and practice for the prevention and forensic medicine for the sudden death of CHD. MaterialThe death identification of CHD(92 males and 29 females) was accepted from February 2015 to February 2012 in the Forensic Medicine Department of Zhengzhou University, and the total is 121 cases. Method:1.The paper uses the SPSS 17.0 system to do statistics analysis. The paper compares all the data between each group by statistical analysis according to the statistical standards P <0.05.2.To investigate the characteristics of age, gender, occupation, inducement, season and pathological changes of sudden death of CHD. Result:1.The characteristics of sudden death of CHD with the age and sexSCD mainly concentrated in the 40- 60 years old, the age before 50 years old in male and female, the morbidity is 3.6:1, after that, the ratio is about 2.7: 1. In any age group, the morbidity of women are lower than those of men.With the increase of age, the morbidity of female gradually increases, but men are stillmain group The age of onset of sudden death of CHD in our country has a younger trend.2.Distribution of sudden death of CHD in the seasonsThe higher incidence is winter and spring, and male patients is more than the female, the difference has statistically significant.3.The characteristic of sudden death of CHD.The most common cause of SCD is agitation. There is no difference between men and weman and the men patients are the main group.4.The characteristic of CHD and Coronary atherosclerotic stenosisThe left anterior descending occurrence of atherosclerotic plaque is the most common, and the the left anterior descending artery stenosis III and IV level is common. The higher the degree of coronary artery stenosis is, the more sudden death of CHD is; left anterior descending artery atherosclerotic plaque in the right coronary artery is the most common situation; The patch type V type plaque is the most common and high incidence types, and is often accompanied by left anterior descending artery; The left anterior descending artery stenosis grade III, IV level is most common; When coronary artery stenosis II level appears sudden death of CHD, coronary artery atherosclerotic plaque is often the type VI composite patch. With the age increasing, the anterior descending coronary artery atherosclerotic stenosis appeares gradually aggravates, which is combined with the increasing age III, IV level, the stenosis rate gradually increases, II stenosis rate gradually decreases.5.The degree of anterior descending stenosis and cardiac changes in sudden CHDIn CHD, when the left anterior descending coronary artery stenosis is III level, the incidence ratio of sudden death in CHD rate highest heart disease is the highest, and the heart lesions appears the most. With the severity of coronary artery stenosis, cardiac lesions emerges an increasing trend. Conclusion:1.In recent years, with the improvement of people’s living standard, the degree of people’s mental tension gradually increases, because the pressure of life and work gradually increases,and the pace of life speeds up and other factors, in China the onset of age of SCD shows a younger trend.2.The incidence of sudden death of CHD in the grade III level of the left anterior descending coronary stenosis is the highest, and it is related to the recessive coronary heart disease.3.The presence of coronary artery malformation, the degree of coronary stenosis reachs II level, the sudden death of CHD is more prone to coronary malformations.4.When the coronary artery stenosis grade II level of coronary heart disease appears death, and coronary artery atherosclerotic plaque composition has certain correlation with it, and is more common in type VI level of atherosclerotic composite patches. |
