Objective To explore the distribution and development characters of the accidental injury and death in urban residents in Chifeng city.Method The data came from the annals of death caused by illness or injury and of the demography of the residents from Hongshan district of the Chifeng city(urban area),Ningcheng county(rural area) and Balin You Banner(pasturing area) during 2001-2003.The causes of the death were classified with ICD-9.Results The mortality of the accidental injury during 2001-2003 were 14.17/100 000 in urban area,48.13/100 000 in rural area and 38.02/100 000 in pasturing area,respectively;and which accounted for 5.63%,10.42% and 9.83% of the total deaths,respectively.The death caused by accidental injury ranked the top 5th in urban and rural areas,and the 4th in pasturing area.The main cause for the potential life losing was traffic accidents of the motor vehicles for men and suicides for women.The mortality of the accidental injury in urban and rural residents of over 20 s yrs was higher,and it was higher in male that in female.Conclusion The main causes for the death of the residents in Chifeng city were traffic accidents,suicides and accidental poisoning.It is necessary to adopt correspond measures and make prevention for it according to the epidemic and different ages and sex characters.

Objective To understand the epidemiological characteristics of hypertension in Chifeng.Methods 6 015 subjects aged over 15 years old were selected with stratified randomized sampling.The history of hypertension and social-economic status were investigated by face-to-face interview and blood pressure,body height,body weight and waistline were measured at the same time.Results The prevalence of hypertension in Chifeng was 28.5%.The age-adjusted prevalence was 19.09%.Thereinto,the prevalence of hypertension in urban area,rural area,pasturing area were 23.15%,19.85%,32.03%,respectively.The Hypertension prevalence in male was increased with age.The prevalence in male was higher than in female among people who lived in urban and pasturing area(P0.05).The prevalence were higher in illiterate person and semiliterate than people in other educational level(P

Objective: To describe the clinical characteristics with long-term prognosis in patients with mid-ventricular obstructive hypertrophic cardiomyopathy (MVOHCM).
Methods: A total of 66 MVOHCM patients treated in our hospital were retrospectively studied for their morbidity, clinical characteristics and mortality. The cumulative survival rate was calculated by Kaplan-Meier method; the risk factors for cardiac death and cardiovascular events were analyzed by uni- and multivariate Cox proportional hazard model.
Results: There were 66 (2.74%) patients suffering from MVOHCM among 2413 patients of hypertrophic cardiomyopathy and the average diagnostic age was (40.16 ± 14.64) years. With (7.30 ± 6.25) years of follow-up study, the cardiovascular mortality was 13.6% and unexplained syncope (HR=13.37, 95% CI: 1.65-114.46, P=0.015) was the independent predictor for cardiovascular death. There were 45.45% (30/66) patients experienced at least 1 time of cardiovascular event and the most frequent one was non-sustained ventricular tachycardia (NSVT); 19.70% (13/66) of patients combined with apical aneurysms, and they were more inclined to experience NSVT.
Conclusion: MVOHCM patients usually have unfavorable prognosis with the higher incidence of cardiovascular events, some patients may develop apical aneurysm. The early diagnosis of MVOHCM is important for appropriate treatment.

OBJECTIVETo compare the clinical features and long-term outcome of patients with midventricular obstructive hypertrophic cardiomyopathy (MVOHCM) and patients with apical hypertrophic cardiomyopathy (AHCM) in China.

METHODSThis retrospective study analyzed clinical data of 66 patients with MVOHCM and 263 patients with AHCM from a consecutive single-center cohort consisting of 2 413 patients with HCM. The clinical features, cardiovascular mortality and morbidity were compared between the two groups.

RESULTSCompared with the AHCM, patients in the MVOHCM group was younger and more likely to be symptomatic over a mean follow-up of 7 years. The proportion of MVOHCM and AHCM were 2.7% (66/2 413) and 10.9% (263/2 413) (P < 0.001), respectively, in this cohort. Cardiovascular mortality of the two groups were 13.6% (9/66) and 0.8% (2/263) (P < 0.001), and cardiovascular morbidity of the two groups were 53.0% (35/66) and 14.4% (38/263) (P < 0.001).

CONCLUSIONMVOHCM is rarer, but the clinical manifestations and long-term outcomes are worse compared with AHCM in this patient cohort.
