BACKGROUNDCoronary heart diseases (CHD) have been identified as one of topmost diseases affecting the Chinese population. However, depression in CHD has not been reported and there are limited high quality empirical studies in China focused on the prevalence of the comorbidity. This study aimed to estimate the pooled prevalence of depression with CHD in China.

METHODSSystematic review and meta-analysis of published epidemiologic studies on the depression in CHD patients in China were conducted. The research findings dated before 30 September 2013 were obtained from Ovid Medline, EMBASE and two Chinese electronic publication libraries WANFANG and CNKI. We used "cardiovascular disease", "depression" and "China" as the search themes in Ovid Medline and EMBASE and "cardiovascular disease" and "depression" in WANFANG and CNKI. Random-effects meta-analysis was used to estimate the prevalence of depression in CHD patients.

RESULTSTwenty-seven studies were included in the review. Twenty-three studies had 5 236 participants who were hospitalized and four studies had 1 353 participants from community. The overall prevalence of depression in CHD from hospital was 51% (95% CI: 0.43, 0.58; I-squared = 97%, P = 0.000).The prevalence of depression in CHD from community ranged between 34.6% to 45.8%, and the severe depression was found ranging between 3.1% to 11.2%.

CONCLUSIONSOn comparing data with other countries, the prevalence of depression in CHD among admitted patients in China was found to be high. The physicians and healthcare providers should pay more attention to the "physical-mental" health of the CHD patients.

Objective: To investigate the relationship between human cytomegalovirus (HCMV) infection and peripheral blood CD14 CD16 monocytes in the pathogenesis of coronary heart disease (CHD), and to elucidate the mechanism of pathogenesis in CHD by analyzing the correlation between infection, inflammation, and CHD, to provide a basis for the prevention, evaluation, and treatment of the disease. Methods: In total, 192 patients with CHD were divided into three groups: latent CHD, angina pectoris, and myocardial infarction. HCMV-IgM and -IgG antibodies were assessed using ELISA; CD14 CD16 monocytes were counted using a five-type automated hematology analyzer; mononuclear cells were assessed using fluorescence-activated cell sorting; and an automatic biochemical analyzer was used to measure the levels of triglyceride, cholesterol, high- and low-density lipoprotein cholesterols, lipoprotein, hs-CRp and Hcy. Results: The positive rates of HCMV-IgM and -IgG were significantly higher in the CHD groups than in the control group. HCMV infection affects lipid metabolism to promote immune and inflammatory responses. Conclusion HCMV infection has a specific correlation with the occurrence and development of CHD. The expression of CD14 CD16 mononuclear cells in the CHD group was increased accordingly and correlated with acute HCMV infection. Thus, HCMV antibody as well as peripheral blood CD14 CD16 mononuclear cells can be used to monitor the occurrence and development of CHD.

OBJECTIVETo assess the clinical significance of ankle-brachial index(ABI) in aged Chinese hypertensive men and to determine the association of ABI with clinical coronary heart disease, stroke.

METHODSAnkle-brachial index (ABI) was measured by means of peripheral vascular lab in aged hypertensive men from 301 Hospital and Anzhen Hospital while the clinical characteristics of the study population were investigated and collected. ABI < or = 0.9 was defined as peripheral arterial disease (PAD), 1.01 - 1.30 as borderline PAD.

RESULTSThere were 244 aged Chinese hypertensive men with antihypertensive treatment and with mean age 76.47 +/- 9.75 enrolled in this study, in whom 15 men with missing data except general information and ABI measurement. The mean ABI was 0.941 +/- 0.258 with the highest frequency 1.01 - 1.30. Eighty five men were diagnosed as PAD, 22 as borderline PAD, 135 normal ABI and 2 with ABI > 1.3. ABI and rate of hypertension control in PAD and borderline PAD men were significantly lower than those with normal ABI. In both PAD and borderline PAD patients, the hypertension duration (except in borderline PAD), creatinine level, neutrophil count (except in borderline PAD), percentage of alcohol drinking, prevalence of diabetes mellitus (except in borderline PAD), coronary artery disease, stroke and dyslipidemia (except in borderline PAD) were significantly higher than those with normal ABI patients. The prevalences of PAD, borderline PAD, coronary artery disease and stroke in this study population were 35.1%, 9.1%, 64.0%, 40.5%, respectively. The prevalences of PAD, borderline PAD, coronary artery disease and stroke increased significantly with increasing age. Logistic regression analysis showed that lower ABI was inversely associated with clinical coronary artery disease and stroke after adjustment for age, body mass index, hypertension duration, rate of hypertension control, systolic blood pressure, diastolic blood pressure, status of smoking, alcohol drinking, diabetes mellitus, dyslipidemia. The fully-adjusted odds ratios (ORs) for PAD and borderline PAD group compared with normal ABI group for the prevalence of coronary artery disease, and stroke demonstrated that these conditions were conversely related to ABI.

CONCLUSIONAged hypertensive men have high prevalence of PAD. Low ABI level was independently associated with coronary artery disease and stroke.

BACKGROUNDThe prevalence of metabolic syndrome (MetS) in hypertensive population in Chinese countryside is unknown. Firstly, this study compared the prevalence of MetS according to National Cholesterol Education Program (NCEP) ATPIII, revised NCEP and International Diabetes Federation (IDF) definitions. Secondly, it investigated the association between MetS, coronary heart disease (CHD) and stroke in patients with hypertension.

METHODSIn this cross sectional study, the cluster sampling method was used. Three MetS definitions were applied to 1418 normal subjects and 5348 hypertensive patients aged 40-75 years in rural areas in China. The agreement between different MetS definitions was estimated by kappa statistics. Logistic regression analyses determined the association between MetS defined by the three MetS definitions and CHD and stroke.

RESULTSIn subjects without hypertension, the prevalence of Mets was 4.1% by NCEP definition, 8.3% revised NCEP definition and 7.8% IDF definition. In hypertensive individuals, the prevalence was 14.0%, 32.9%, and 27.4% in men; 35.6%, 53.1%, and 50.2% in women by the same definitions, respectively. In hypertensive individuals, the agreement was 94.4% in men and 97.0% in women between revised NCEP and IDF definitions. The IDF defined MetS was more strongly associated with CHD than the NCEP or revised NCEP defined MetS (adjusted odds ratio: 1.92 compared with 1.85 and 1.69 in men; 1.64 compared with 1.48 and 1.60 in women).

CONCLUSIONSIn the patients with hypertension, the revised NCEP and IDF definitions identified more individuals than NCEP definition and their agreement is very high. The IDF defined MetS is more strongly associated with CHD than the NCEP or revised NCEP defined MetS, but weakly or not associated with stroke.

OBJECTIVETo determine the association of cigarette smoking and coronary artery diseases (CAD).

METHODSA case-control study involving 355 people classified as CAD or without CAD was performed. But people treated with diuretic, aspirin, lipid-lowering agents, heparin or those with renal, hepatic diseases were excluded. Gender, age, body mass index, plasma glucose under fasting, total cholesterol, triglyceride, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fibrinogen, cigarette smoking consumption grade (0: no smoking, 1: less or equal 100 cigarette year, 2: one hundred cigarette year < cigarette index

RESULTSIn multiple logistic regression, age, gender, fasting plasma glucose, fibrinogen and cigarette smoking showed significant independent association with CAD. Compared with non-smoker, the odds ratio (OR) of CAD of grade 3-cigarette smoking was 3.519 (95% CI: 1.538 - 8.053, P = 0.003). However with grade 1 cigarette smoking group, no significant independent association was found with CAD (OR = 0.948, P = 0.959). With more than grade 2 [grade 2 + 3, compared with less than grade 2 (0 + 1)] and grade 3 [compared with less than grade 3 (0 + 1 + 2)] cigarette smoking, ORs of CAD were 2.094 (P = 0.027), 3.463 (P = 0.002) respectively. Three hundred fifty-five people were divided into 3 groups: control, stable angina (SA) and unstable angina (UA) groups. In multinomial logistic regression, when comparing with UA, parameter estimate of cigarette smoking degree in the SA group were beta = -0.220, s(x) = 0.138, P = 0.112, OR = 0.803 respectively.

CONCLUSIONSCigarette smoking was a significant independent risk factor for CAD. With more cigarettes smoked, a higher odds ratio of CAD was seen. Gender, age, fibrinogen and plasma glucose during fasting were also independent factors significantly associated with CAD. No significant independent association between cigarette smoking and unstable angina was found.

OBJECTIVETo explore the association of metabolic syndrome with CVD in a cohort study involving 11 provinces.

METHODSA cohort study was carried out in a population of 27 739 subjects (age 35 - 64 years). A baseline survey on the risk factor of cardiovascular disease was done in 1992. Incidence rate and relative risk were calculated for metabolic syndromes.

RESULTS(1) The age-standardized incidence rate of cardiovascular disease for metabolic syndromes (MS) was higher than those without (MS) in this cohort (MS 652.3/100,000, not MS 206.7/100,000, RR = 3.12, P < 0.001). (2) The incidence rate of cardiovascular disease for patients with hypertension but low HDL cholesterol and high waist was the highest (910.2/100,000 in man, 930.7/100,000 in woman) among all metabolic syndromes patients. (3) The predictive risk factors for cardiovascular disease were age, cigarette smoking, BMI, total cholesterol and metabolic syndrome in men, with age, BMI and metabolic syndrome in women.

CONCLUSIONThe incidence rate of cardiovascular disease on the metabolic syndrome was high in 11 provinces in China. Age, BMI and metabolic syndrome were the predictive risk factors of cardiovascular disease (especially of cerebrovascular disease). It is essential to prevent risk factors of cardiovascular disease in primary and secondary prevention programs in general population.

This prospective study surveyed the prevalence of peripheral arterial disease (PAD) in Korean patients with coronary arterial disease (CAD) or cerebrovascular disorder (CVD). From March 2010, 576 hospitalized patients in cardiovascular or stroke center were enrolled as the study group. Ankle-brachial index (ABI) was measured and the cut-off point for diagnosing PAD was < or = 0.9 at rest. A total of 424 hospitalized patients in the Department of Surgery and aged > or = 50 yr was enrolled as the control group. The prevalence of PAD was significantly higher in the study group than the control group (7.6% vs 1.7%; P < 0.001). To analyze the relationship of other vascular diseases and PAD, the patients were regrouped; group A (no CAD or CVD), group B (CAD only), group C (CVD only), and group D (CAD and CVD). Compared with group A, those with other vascular diseases (group B, C, D) had significantly higher prevalence of PAD, diabetes, dyslipidemia, renal insufficiency and claudication. The trend that patients with CAD or CVD are at risk of PAD is observed in this cross-sectional study in Koreans. Routine ABI measurement is recommended in these high-risk groups for early detection and proper management of PAD.

OBJECTIVEWe aimed to investigate the cumulative effect of high CRP level and apolipoprotein B-to-apolipoprotein A-1 (ApoB/ApoA-1) ratio on the incidence of ischemic stroke (IS) or coronary heart disease (CHD) in a Mongolian population in China.

METHODSFrom June 2003 to July 2012, 2589 Mongolian participants were followed up for IS and CHD events based on baseline investigation. All the participants were divided into four subgroups according to C-reactive protein (CRP) level and ApoB/ApoA-1 ratio. Cox proportional hazard models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for the IS and CHD events in all the subgroups.

RESULTSThe HRs (95% CI) for IS and CHD were 1.33 (0.84-2.12), 1.14 (0.69-1.88), and 1.91 (1.17-3.11) in the 'low CRP level with high ApoB/ApoA-1', 'high CRP level with low ApoB/ApoA-1', and 'high CRP level with high ApoB/ApoA-1' subgroups, respectively, in comparison with the 'low CRP level with low ApoB/ApoA-1' subgroup. The risks of IS and CHD events was highest in the 'high CRP level with high ApoB/ApoA-1' subgroup, with statistical significance.

CONCLUSIONHigh CRP level with high ApoB/ApoA-1 ratio was associated with the highest risks of IS and CHD in the Mongolian population. This study suggests that the combination of high CRP and ApoB/ApoA-1 ratio may improve the assessment of future risk of developing IS and CHD in the general population.
