ABSTRACT
BACKGROUND@#Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps.@*METHODS@#A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis.@*RESULTS@#During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed.@*CONCLUSIONS@#ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

Objective@#To explore the clinical characteristics and prognosis of the new coronavirus 2019-nCoV patients combined with cardiovascular disease (CVD).@*Methods@#A retrospective analysis was performed on 112 COVID-19 patients with CVD admitted to the western district of Union Hospital in Wuhan, from January 20, 2020 to February 15, 2020. They were divided into critical group (ICU, n=16) and general group (n=96) according to the severity of the disease and patients were followed up to the clinical endpoint. The observation indicators included total blood count, C-reactive protein (CRP), arterial blood gas analysis, myocardial injury markers, coagulation function, liver and kidney function, electrolyte, procalcitonin (PCT), B-type natriuretic peptide (BNP), blood lipid, pulmonary CT and pathogen detection.@*Results@#Compared with the general group, the lymphocyte count (0.74×109 (0.34×109, 0.94×109)/L vs. 0.99×109 (0.71×109, 1.29×109)/L, P=0.03) was extremely lower in the critical group, CRP (106.98 (81.57, 135.76) mg/L vs. 34.34 (9.55,76.54) mg/L, P<0.001) and PCT (0.20 (0.15,0.48) μg/L vs. 0.11 (0.06,0.20)μg/L, P<0.001) were significantly higher in the critical group. The BMI of the critical group was significantly higher than that of the general group (25.5 (23.0, 27.5) kg/m2 vs. 22.0 (20.0, 24.0) kg/m2, P=0.003). Patients were further divided into non-survivor group (17, 15.18%) group and survivor group (95, 84.82%). Among the non-survivors, there were 88.24% (15/17) patients with BMI> 25 kg/m2, which was significantly higher than that of survivors (18.95% (18/95), P<0.001). Compared with the survived patients, oxygenation index (130 (102, 415) vs. 434 (410, 444), P<0.001) was significantly lower and lactic acid (1.70 (1.30, 3.00) mmol/L vs. 1.20 (1.10, 1.60) mmol/L, P<0.001) was significantly higher in the non-survivors. There was no significant difference in the proportion of ACEI/ARB medication between the critical group and the general group or between non-survivors and survivors (all P>0.05).@*Conclusion@#COVID-19 patients combined with CVD are associated with a higher risk of mortality. Critical patients are characterized with lower lymphocyte counts. Higher BMI are more often seen in critical patients and non-survivor. ACEI/ARB use does not affect the morbidity and mortality of COVID-19 combined with CVD. Aggravating causes of death include fulminant inflammation, lactic acid accumulation and thrombotic events.
ABSTRACT
Objective@#To explore the relationship between anthropometric indices and the incident risk of hypertension, compare novel anthropometric indices with traditional indices in hypertension prediction and establish hypertension prediction models among elderly Chinese.@*Methods@#A total of 27 009 retirees from the Dongfeng Motor Corporation were recruited at baseline in 2008 and the first follow-up was conducted in 2013. After the exclusion of participants less than 60 years old, participants with hypertension, coronary heart disease, stroke, cancer, and those with missing data, a total of 6 784 elderly participants were enrolled in this study. A multivariate logistic regression model was used to analyze the relationship between traditional anthropometric indices, body mass index (BMI), waist circumference (WC), waist-to-height ratio (WHtR), novel anthropometric indices, visceral adiposity index (VAI), body shape index (ABSI), body roundness index (BRI), and the incident risk of hypertension. Meanwhile, a multivariate logistic regression model was used to establish hypertension prediction models. Receiver operating characteristic (ROC) curve was applied to compare the prediction ability of different models.@*Results@#A total of 1 787 incident cases of hypertension were identified, with the incidence of hypertension about 27.59%. Significant positive associations were detected between BMI, WC, WHtR, VAI, BRI and the incident risk of hypertension after adjusting for potential confounders (all P values<0.05). In men, the OR (95%CI) (upper tertile vs lower tertile) was 1.45 (1.22-1.73) for VAI, and 1.86 (1.55-2.23) for BRI. In women, the OR (95% CI) (upper tertile vs lower tertile) was 1.55 (1.22-1.96) for VAI, and 1.60 (1.27-2.01) for BRI. For ABSI, no significant association was observed in either men (OR (95%CI): 1.07 (0.90-1.28)) or women (OR (95%CI): 1.03 (0.82-1.29), both P values >0.05). The basic hypertension prediction model included age, drinking (only in men), education status (only in men), systolic blood pressure (SBP), diastolic blood pressure (DBP), and fasting blood glucose levels. Based on the basic prediction model, BMI (in men: AUC=0.697) and BRI (only in men: AUC=0.696) improved area under ROC curve (AUC) significantly (P<0.05). BMI was the strongest predictor in both men (AUC=0.697) and women (AUC=0.685) in the extended model.@*Conclusion@#Significant positive associations were detected between BMI, WC, WHtR, VAI, BRI and the incident risk of hypertension among elderly Chinese. BMI was the strongest predictor in hypertension prediction model compared with other anthropometric indices.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effects of rs10916581, a common single nucleotide polymorphism (SNP) located in the promoter region of pre-miR-320b-2, on coronary heart disease (CHD) risk and circulating microRNA-320b (miR-320b) level. To explore potential factors influencing circulating miR-320b level.</p><p><b>METHODS</b>Rs10916581 was genotyped in a case-control study with 1 507 CHD cases and 1 379 age- and sex-frequency-matched controls. The cases were consecutively recruited from 3 hospitals (Tongji Hospital, Union Hospital, and Wugang Hospital) in Wuhan city (Hubei, China) between May 2004 and October 2009 and all the controls resided in Wuhan communities. A subgroup of 174 CHD cases and 181 non-diabetes controls without acute infection were randomly selected and their circulating miR-320b levels were detected using quantitative reverse transcriptase polymerase chain reaction assays. The association of rs10916581 with CHD susceptibility was analyzed with multivariable logistic regression model. Generalized linear regression model was used to explore the associations of rs10916581 and some other factors with circulating miR-320b level.</p><p><b>RESULTS</b>In single-factor logistic regression analysis, no association was found between rs10916581 and CHD risk. After adjustment for age, sex, BMI, smoking status, hypertension, diabetes, total triglyceride, total cholesterol/high density lipoprotein (TC/HDL-C), the result did not materially alter(compared with CC genotype, the OR (95%CI) of CHR in the subjects carried CT, TT, CT+TT genotypes were 0.94 (0.76-1.15), 0.99 (0.74-1.33) and 0.95 (0.78-1.16) ). No significant interactions were observed between the conventional risk factors of CHD (age, gender, smoking status, BMI, hypertension, diabetes, CHD family history) and rs10916581 on CHD risk (P > 0.05). Rs10916581 showed no significant association with circulating miR-320b level in cases, controls or total population (β(95%CI) was -0.028 (-0.495-0.440), 0.250 (-0.226-0.727) and 0.134 (-0.218-0.486) respectively, P > 0.05). However, circulating miR-320b level was negatively associated with BMI (β (95%CI) was -0.140 (-0.261--0.020), P = 0.022) while positively associated with TC/HDL(β (95%CI) was 0.620 (0.261-0.979), P = 0.001) in cases, and in total population, its circulating level tended to be lower in diabetes or hypertension patients (β(95%CI) was -1.025 (-1.696--0.354) and -0.594 (-1.138--0.049) respectively, P = 0.003, 0.033 respectively) and was positively associated with TC/HDL-C (β(95%CI) was 0.108 (0.027-0.190), P = 0.009).</p><p><b>CONCLUSION</b>The common SNP (rs10916581) in the promoter region of pre-miR-320b-2 might have little contribution to the CHD predisposition in Chinese Han population, and it might not affect circulating miR-320b level. Conventional CHD risk factors (BMI, TC/HDL-C, hypertension and diabetes) might have effects on its circulating level.</p>

In order to investigate the association of G+1688A (Ser563Asn) polymorphism of platelet endothelial cell adhesion molecule-1 (PECAM-1) gene with myocardial infarction (MI) in the Chi- nese Han population, the G+1688A polymorphism in PECAM-1 gene was detected by polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) method among 502 subjects, including 218 patients with MI and 284 controls. The results showed that there was significant dif-ference in AA frequencies of genotype G+1688A polymorphism between case and control groups (39% vs 24%, P<0.001). A similar trend was observed on the allele frequencies (A/G: 62% vs 49%, P<0.001). Among the subjects with high serum total cholesterol level or high systolic blood pressure level, the variant AA genotype was associated with high risk of MI (adjusted OR, 2.13; 95% CI, 1.08-4.41 and adjusted OR, 2.53; 95%CI, 1.63-3.63). The single nucleotide polymorphism (SNP) at position +1688 in the exon 8 of PECAM-1 gene was associated with MI and the allele A might be a risk factor for MI in the Chinese Han population.
ABSTRACT
The association between atrial natriuretic peptide (ANP) polymorphism and coronary heart disease (CHD) was studied in Chinese population. The genotypes of ANP T2238C and ANP C-664G were detected by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) methods in 158 consecutive CHD patients and 165 controls. It was found that the distribution of A2A2 genotype in CHD group was significantly higher than that in control group (P＜0.05). Stepwise Logistic regression analysis revealed that male, smoking, history of hypertension,history of diabetes, family history of hypertension, high level of serum cholesterol, and ANP T2238C polymorphism were the possible risk factors in patients with CHD (P＜0.05). However, there was no significant difference between the patients with CHD and the control group in the distribution of ANP C-664G polymorphism (P＞0.05). The results suggest that A2A2 T2238C genotype could be one of the risk factors for CHD (P＜0.05, OR: 1.80, 95% CI:1.03-3.15).
