Major and profound changes have taken place in China over the past 30 years. Rapid socioeconomic progress has exerted a great impact on lifestyle, ranging from food, clothing, working and living conditions, and means of transportation to leisure activities and entertainment. At the same time, new health problems have emerged, and health services are facing new challenges. Presently, cardiovascular diseases (CVD) are among the top health problems of the Chinese people, and pose a serious challenge to all engaged in the prevention and control of these diseases. An epidemic of CVD in China is emerging as a result of lifestyle changes, urbanization and longevity. Both national policy decision-making and medical practice urgently need an authoritative report which comprehensively reflects the trends in the epidemic of CVD and current preventive measures. Since 2005, guided by the Bureau of Disease Prevention of the Ministry of Health of the People's Republic of China and the National Center for Cardiovascular Diseases of China, nationwide experts in the fields of epidemiology, clinical medicine and health economics in the realms of CVD, cerebrovascular disease, diabetes and chronic kidney disease, completed the Report on Cardiovascular Diseases in China every year. The report aims to provide a timely review of the trend of the epidemic and to assess the progress of prevention and control of CVD. In addition, as the report is authoritative, representative and readable, it will become an information platform in the CVD field and an important reference book for government, academic institutes, medical organizations and clinical physicians. This publication is expected to play a positive role in the prevention and control of CVD in China. We present an abstract from the Report on Cardiovascular Diseases in China (2010), including trends in CVD, morbidity and mortality of major CVDs, up-to-date assessment of risk factors, as well as health resources for CVD, and a profile of medical expenditure, with the aim of providing evidence for decision-making in CVD prevention and control programs in China, and of delivering the most authoritative information on CVD prevention and control for all citizens.

Over the past two decades, with the improvement of living standards and the change of lifestyle, the incidence of stroke in young adults had been increasing year by year. Compared with elderly patients, young patients had a higher proportion of intracranial and subarachnoid hemorrhage. The etiologies of ischemic stroke in young patients were more diverse, with increasing risk factors such as hypertension, diabetes, smoking, alcoholism, and oral contraceptives. Due to the atypical clinical symptoms, various etiologies, the clinical inertia of the receiving physicians and the concerns about the use of statins in young stroke patients, timely diagnosis and standardized treatment are still challenging. China has been providing medical assistance to African countries for nearly 60 years. Considering the regional differences in medical level between China and Africa, in order to help Chinese medical teams to have a deep understanding of the current situation of stroke in young African adults, this paper comprehensively analyzed the epidemiology, etiology, risk factors and prevention measures of stroke in young adults, especially in Chinese and African, which could provide corresponding reference for early identification, treatment, prevention and education of stroke in young people.

Youth is the core force of social and economic development, once the occurrence of youth stroke will place a heavy burden on society and family. However, the prevention and control of stroke in China is mainly aimed at middle-aged and elderly patients, the part of young stroke is relatively easy to be ignored. This article focuses on the characteristics, research progress, prevention and control status of young stroke, pointing out the importance of centering on the prevention and treatment of young stroke. At the same time, it hopes that the industry can concentrate on the prevention and treatment of young stroke, making precise policies in the future, and developing secondary prevention guidelines for the causes or risk factors of young stroke, so as to improve comprehensive stroke prevention and control system. On this basis, the health level of the whole population will be improved, and the life expectancy of residents will be extended, thus promoting the realization of the strategic goal of "Healthy China 2030".

OBJECTIVEThe aim of the study was to investigate the association between tea consumption and stroke.

METHODSA cross sectional study was conducted in autumn, 1998. The subjects were from 12 provinces in China. 15 groups of populations were selected by cluster randomized sampling and each group had about 1000 persons, aged from 35 to 60 years old. 14 212 subjects had complete data for analysis. Data regarding tea drinking would include drinking status, dose and type of teas. Logistic regression was used to analyze the association between tea consumption and stroke.

RESULTSThere was a strong inverse correlation between tea drinking and stroke after adjusting other risk factors of stroke (P < 0.05). The odds ratio (OR) of stroke was 0.60 [95% confidence interval (CI): 0.42 - 0.85] for subjects who drank tea compared to those who did not. Increased amount of tea consumption per month was associated with decreased stroke prevalence. The association for tea consumption over 150 gram per month and stroke was statistically significant (P < 0.05) with an OR value of 0.56 (95% CI: 0.36 - 0.89). Analytical results indicated that the OR value was 0.24 (95% CI: 0.06 - 1.01) for black tea and other tea (P = 0.05). The OR value was 0.35 (95% CI: 0.18 - 0.72) for green tea (P < 0.01), and 0.75 (95% CI: 0.51 - 1.11) for jasmine tea (P > 0.05).

CONCLUSIONTea drinking was independently associated with prevalence of stroke which might play a role in the prevention of the disease.

Stroke is one of the leading causes of deaths in Korea. According to the report from Korean National Statistical Office, the mortality rate of stroke was 77.2/100,000 persons in 2002. In the past, hemorrhagic stroke was more prevalent than ischemic stroke in Korea. However, the ratio of hemorrhagic to ischemic stroke has been reversed since late-1980s. This trend might be due to the westernization of lifestyle as well as better control of stroke risk factors such as hypertension and diabetes. Of ischemic stroke, the incidence of cardioembolism is relatively low in Korea compared with in Western countries, especially in posterior circulation disorders. This observation reflects the epidemiologic characteristic of stroke in Korea where the prevalence of cardiac diseases is relatively low. The case fatality rate from one of the largest hospital-based stroke registries was 7.7% within 30 days after the onset of acute ischemic stroke, which is similar to those from other series in western countries with advanced medical care systems. However, the delay of hospital visit after the onset of stroke and the lower compliance for secondary prevention remain obstacles in managing stroke patients in Korea.

PURPOSE: Atrial fibrillation (AF) is one of the major risk factors for ischemic stroke, and 90% of thromboembolisms in these patients arise from the left atrial appendage (LAA). Recently, it has been documented that an LAA occlusion device (OD) is not inferior to warfarin therapy, and that it reduces mortality and risk of stroke in patients with AF. MATERIALS AND METHODS: We implanted LAA-ODs in 5 Korean patients (all male, 59.8+/-7.3 years old) with long-standing persistent AF or permanent AF via a percutaneous trans-septal approach. RESULTS: 1) The major reasons for LAA-OD implantation were high risk of recurrent stroke (80%), labile international neutralizing ratio with hemorrhage (60%), and 3/5 (60%) patients had a past history of failed cardioversion for rhythm control. 2) The mean LA size was 51.3+/-5.0 mm and LAA size was 25.1x30.1 mm. We implanted the LAA-OD (28.8+/-3.4 mm device) successfully in all 5 patients with no complications. 3) After eight weeks of anticoagulation, all patients switched from warfarin to anti-platelet agent after confirmation of successful LAA occlusion by trans-esophageal echocardiography. CONCLUSION: We report on our early experience with LAA-OD deployment in patients with 1) persistent or permanent AF who cannot tolerate anticoagulation despite significant risk of ischemic stroke, or 2) recurrent stroke in patients who are unable to maintain sinus rhythm.

OBJECTIVETo evaluate the effectiveness of stroke prevention among high risk population, using Nao'an Capsules.

METHODSParticipants were selected from 696,558 residents in Nanhui, using county of Shanghai city. Individuals aged 35 years old and over with at least one risk factor exposure to stroke, received cerebral vascular hemodynamic examination. 18,271 cases meeting the criteria of cerebral vascular hemodynamic indexes accumulative score below 70 points were defined as individuals with high-risk and targets to receive intervention. According to the willingness of the participants, 10,313 cases received Nao'an Capsules for intensive intervention based on general intervention measures compared to 7958 cases only receiving general intervention. After the implementation of intervention, incidence and mortality rates of stroke and the effectiveness of three-year intervention were studied.

RESULTSIncidence of stroke in Nao'an Capsules group was significantly lower than that of the general intervention (P < 0.01) with 53.8% in males and 58.4% in females. The relative risk (RR) in two gender groups were 0.46 (0.33 - 0.64) and 0.39 (0.30 - 0.50) respectively. Multiple logistic regression analysis indicated that the history of hypertension, accumulative score of cerebral vascular hemodynamic indexes, age, gender and Nao'an Capsules intervention were the variables selected into the equation and significantly related to stroke. Among the variables, Nao'an Capsule was the strongest factor with a RR of 0.41.

CONCLUSIONIncidence of stroke in Nao'an Capsule intervention group was significantly lower than that in the general intervention group after 3 years of intervention, suggesting that Nao'an Capsule intervention was the strongest factor affecting stroke occurrence in individuals at high-risk.

OBJECTIVETo evaluate the community-based intervention on reduction of hypertension and stroke in different age groups and subtypes hypertension.

METHODSIn 6 cities, 2 geographically separated communities with a registered population about 10 000 of each were selected as either intervention or control communities. A cohort containing 2 700 subjects, 35 years or older, and free of stroke were sampled from each community. The baseline survey was conducted to screen the subjects for intervention. In each city, a program for control of hypertension, heart diseases and diabetes was initiated in the intervention cohort and health education was provided to the whole intervention community. A follow-up survey was conducted 3 years later.

RESULTSWithin 3 years, the prevalence of hypertension increased in both intervention and control cohorts, as well as in the middle and elderly cohorts, especially in the middle aged in control group. Among hypertensives in the intervention cohort, the rates of awareness, treatment and control of hypertension got improved. The incidence of stroke was 29% lower (HR = 0.71, 95% CI: 0.58 - 0.87) and mortality of stroke was 40% lower (HR = 0.60, 95% CI: 0.42 - 0.86) in the intervention cohort than the control cohort. The intervention was most effective in reduction of stroke for those with isolated systolic hypertension and combined systolic and diastolic hypertension (All P < 0.05). Meanwhile, all-cause mortality was 11% lower (HR = 0.89, 95% CI: 0.78 - 0.99) in the intervention cohort than in the control cohort.

CONCLUSIONThe community-based intervention was effective in controlling the development of hypertension and stroke, while the elderly people benefit more than the middle aged people from the intervention.
