Study on the impact and clinical effect of high-quality nursing intervention on the quality of life of elderly cataract patients.

Objective: To evaluate the impact and clinical effect of high-quality nursing intervention on the quality of life of elderly cataract patients and its clinical effect. Methods: This is a clinical comparative study. One hundred and twenty elderly cataract patients admitted to Tianjin Medical University Eye Hospital for surgical treatment were recruited and randomly divided into two groups: the control and experimental group, with 60 cases in each group from January 15, 2021 to January 15, 2022. Patients in the control group were given conventional nursing care in the perioperative period, while those in the experimental group were given high-quality nursing intervention in the perioperative period. The differences in anxiety (SAS) scores, depression (SDS) scores, intraocular pressure (IOP) recovery, the incidence of surgical complications and satisfaction before and after treatment between the two groups were compared and analyzed. Results: No statistically significant difference was observed between the two groups in physical functioning, psychological functioning, social functioning and material life status scores before intervention(P>0.05). After the intervention, the above indicators improved significantly in the experimental group compared to the control group, with statistically significant differences (P=0.00). Moreover, SAS and SDS decreased significantly in the experimental group compared to the control group, with statistically significant differences(P=0.00). Conclusions: High-quality nursing intervention improves various benefits in the treatment of elderly cataract patients, such as effectively reducing intraocular pressure, ameliorating patients' quality of life, lowering the incidence of postoperative complications, and improving patient satisfaction.

Asymptomatic atrial fibrillation among hospitalized patients: clinical correlates and in-hospital outcomes in Improving Care for Cardiovascular Disease in China-Atrial Fibrillation.

AIMS: The clinical correlates and outcomes of asymptomatic atrial fibrillation (AF) in hospitalized patients are largely unknown. We aimed to investigate the clinical correlates and in-hospital outcomes of asymptomatic AF in hospitalized Chinese patients. METHODS AND RESULTS: We conducted a cross-sectional registry study of inpatients with AF enrolled in the Improving Care for Cardiovascular Disease in China-Atrial Fibrillation Project between February 2015 and December 2019. We investigated the clinical characteristics of asymptomatic AF and the association between the clinical correlates and the in-hospital outcomes of asymptomatic AF. Asymptomatic and symptomatic AF were defined according to the European Heart Rhythm Association score. Asymptomatic patients were more commonly males (56.3%) and had more comorbidities such as hypertension (57.4%), diabetes mellitus (18.6%), peripheral artery disease (PAD; 2.3%), coronary artery disease (55.5%), previous history of stroke/transient ischaemic attack (TIA; 17.9%), and myocardial infarction (MI; 5.4%); however, they had less prevalent heart failure (9.6%) or left ventricular ejection fractions ≤40% (7.3%). Asymptomatic patients were more often hospitalized with a non-AF diagnosis as the main diagnosis and were more commonly first diagnosed with AF (23.9%) and long-standing persistent/permanent AF (17.0%). The independent determinants of asymptomatic presentation were male sex, long-standing persistent AF/permanent AF, previous history of stroke/TIA, MI, PAD, and previous treatment with anti-platelet drugs. The incidence of in-hospital clinical events such as all-cause death, ischaemic stroke/TIA, and acute coronary syndrome (ACS) was higher in asymptomatic patients than in symptomatic patients, and asymptomatic clinical status was an independent risk factor for in-hospital all-cause death, ischaemic stroke/TIA, and ACS. CONCLUSION: Asymptomatic AF is common among hospitalized patients with AF. Asymptomatic clinical status is associated with male sex, comorbidities, and a higher risk of in-hospital outcomes. The adoption of effective management strategies for patients with AF should not be solely based on clinical symptoms.

Trends in ethnic disparities in clinical cardiovascular health among Chinese adults from 2016-2020.

BACKGROUND AND AIMS: Little is known about the long-term trends in ethnic differences in cardiovascular health (CVH) in China in recent years. This study aimed to investigate ethnic differences in CVH and identify long-term trends in China. METHODS AND RESULTS: This survey was based on the physical examination data of Tacheng Prefecture in China from 2016 to 2020, and included 1,947,938 physical examination participants aged over 20 years for analysis. The American Heart Association (AHA) criteria were used to evaluate the clinical CVH of the subjects. The time trends from 2016 to 2020 were assessed using a weighted linear regression model stratified by ethnicity. The ethnic groups included Han, Kazakh, Hui, Mongolian, Uyghur, among others. The mean ideal clinical cardiovascular score was highest in Hui and lowest in Uyghur. The scores increased from 5.99 (5.95-6.03) to 6.11 (6.08-6.14) in Kazakh males and from 6.05 (5.99-6.11) to 6.11 (6.06-6.16) in Hui males among participants (Plinear trend < 0.001). The scores for the other groups declined significantly from 2016 to 2020(Plinear trend ＜ 0.05). In the sensitivity analysis, the trend remained unchanged after calculating the body mass index (BMI) cut-off for China. CONCLUSION: Clinical CVH differences still exist among different ethnic groups, with a decline in CVH from 2016 to 2020 in all except Kazakh and Hui males. This may indicate a higher incidence and poorer prognosis of cardiovascular disease in the future and can provide guidelines for improving CVH.

Sex-modified association between grip strength and mild cognitive impairment: a cross-sectional and follow-up study in rural China.

BACKGROUND: The sex difference in the association between grip strength and mild cognitive impairment (MCI) remains controversial and unclear. METHODS: This is a part of a chronic disease cohort study conducted in rural areas, Fuxin, Liaoning Province, China. At the baseline survey, a total of 2633 participants aged 35- 85 were included in the cross-sectional study. Handgrip strength (HGS, kg) was measured by a dynamometer (Jamar +). MCI were assessed using the Chinese version of the Montreal Cognitive Assessment-Basic (MOCA-BC). Then, a total of 1667 cognitively normal individuals (NCs) were planed to follow up and to assess the incident MCI after two years. We used logistic regression to examine the association between HGS (as a continuous variable and quintiles) and MCI and analyzed the interaction between sex and HGS on MCI. Models stratified by sex were adjusted for demographic information (age, ethnicity, education, marital status, income, physical labor level), modifiable risk factors (body mass index, smoking, drinking) and disease history (hypertension, diabetes, dyslipidemia and coronary heart disease). Baseline MOCA-BC scores were additionally adjusted in the longitudinal study. RESULTS: In the cross-sectional study, participants were on average 56.6 ± 9.8 years, and 1713 (65.1%) were females. In the cohort study, 743 individuals were followed up with an average age of 55.9 ± 9.6 years, which included 530 (71.3%) females. The cumulative incidence of MCI over a two-year period was 17.1%. In the cross-sectional study, compared to the highest quintile of HGS, the lowest HGS was associated with higher risk of MCI in males (odds ratio [OR]: 2.66; 95% confidence interval [CI]: 1.54, 4.64) and females (OR: 1.70; 95% CI: 1.17, 2.49) with adjustment of potential confounding factors. In the cohort study, compared to the highest quintile of HGS, the lowest HGS was associated with an increased risk of incident MCI in females (OR: 3.93; 95% CI: 1.39, 13.01) but not in males (OR: 0.56; 95% CI: 0.11, 2.94, P for interaction = 0.015). CONCLUSIONS: Lower grip strength is a risk factor for mild cognitive impairment and predicts a higher risk of MCI in females.

A radiomic nomogram for prediction of major adverse cardiac events in ST-segment elevation myocardial infarction.

OBJECTIVES: This study was conducted to establish and validate a non-contrast T1 map-based radiomic nomogram for predicting major adverse cardiac events (MACEs) in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). METHODS: This retrospective study included 157 consecutive patients (training sets, 109 patients; test sets, 48 patients) with acute STEMI undergoing PCI. An open-source radiomics software was used to segment the myocardium on the non-contrast T1 mapping and extract features. A radiomic signature was constructed to predict MACEs using the least absolute shrinkage and selection operator method. The performance of the radiomic nomogram for predicting MACEs in both the training and test sets was evaluated by its discrimination, calibration, and clinical usefulness. RESULTS: The radiomic signature showed a good prognostic ability in the training sets with an AUC of 0.94 (95% CI, 0.86 to 1.00) and F1 score of 0.71, which was confirmed in the test sets with an AUC of 0.90 (95% CI, 0.74 to 1.00) and F1 score of 0.62. The nomogram consisting of the radiomic scores and cardiac troponin I showed good discrimination ability in the training and test sets with AUCs of 0.96 (95% CI, 0.91 to 1.00; F1 score, 0.71) and 0.94 (95% CI, 0.83 to 1.00; F1 score, 0.70), respectively. CONCLUSIONS: The non-contrast T1 map-based radiomic nomogram is a useful tool for the prediction of MACEs in patients with acute STEMI undergoing PCI that can assist clinicians for optimised risk stratification of individual patients. KEY POINTS: • Radiomic signature improved MACE prediction in acute STEMI patients. • T1 mapping-derived radiomic signature outperformed conventional cardiac MRI parameters in predicting MACEs in acute STEMI patients. • The non-contrast T1 mapping-based radiomic nomogram can be used for prediction of MACEs and improvement of risk stratification in acute STEMI.

Transcatheter closure of ventricular septal rupture with prolonged support of intra-aortic balloon pump after primary PCI: a case report.

BACKGROUND: Ventricular septal rupture (VSR) is a rare but severe complication of acute myocardial infarction (AMI). For such cases, surgical repair is recommended by major guidelines, but not always possible for such cases. CASE PRESENTATION: A 72-year-old man presented to the emergency room. ECG showed the ST-segment was elevated by 2-3 mm in lead II, III, and aVF, with Q-waves. Coronary angiography (CAG) showed multi-vessel disease with a total occlusion of the right coronary artery (RCA) and severe stenosis of the left anterior descending artery (LAD). A diagnosis of acute inferior myocardial infarction was made. VSR occurred immediately after percutaneous coronary intervention (a 2.5 × 20 mm drug-eluting stent implanted in RCA), and the patient developed cardiogenic shock. An intra-aortic balloon pump (IABP) was used to stabilize the hemodynamics. Transthoracic echocardiography (TTE) revealed an 11.4-mm left-to-right shunt in the interventricular septum. An attempt was made to reduce the IABP augmentation ratio for weaning on day 12 but failed. Transcatheter closure was conducted using a 24-mm double-umbrella occluder on day 28. The patient was weaned from IABP on day 31 and underwent secondary PCI for LAD lesions on day 35. The patient was discharged on day 41. Upon the last follow-up 6 years later, CAG and TTE revealed no in-stent restenosis, no left-to-right shunt, and 51% left ventricular ejection fraction. CONCLUSIONS: Prolonged implementation of IABP can be a viable option to allow deferred closure of VSR in AMI patients, and transcatheter closure may be considered as a second choice for the selected senior and vulnerable patients, but the risk is still high.

Putting the glass down may keep the stroke away: Results from a prospective cohort study in rural China.

BACKGROUND AND AIMS: Most studies assess the relationship between alcohol and stroke at some point. Little is known about the effect on stroke of drinking status changes over time. This study aimed to examine the association of median 2.4-year drinking status changes with risk of stroke. METHODS AND RESULTS: We examined 22,691 adults from rural China. Drinking status was assessed at 2004-2006 and in 2008. Participants were divided into four change patterns: consistent non-drinkers, abstainers, starters, and consistent drinkers. A Cox proportional hazards model were performed. We observed 1215 cases of stroke during a median follow-up period of 11.8 years. A faint J-shaped association between alcohol consumption and risk of stroke was found in this population. Based on the amount of alcohol consumption, only current drinkers with ≥721 g/week at baseline in both males and females had a higher risk of stroke [hazard ratio (HR): 1.342; 95% confidence interval (CI): 1.070-1.683 and HR: 2.130; CI: 1.041-4.357, respectively]. Based on change patterns, Compared with consistent non-drinkers, the HR (95% CI) for consistent drinkers, abstainers and starters was 1.298 (1.070-1.576), 1.093 (0.877-1.362) and 1.263 (1.034-1.543), respectively. The same trend was observed in male. The HR (95% CI) for consistent drinkers, abstainers and starters was 1.360 (1.098-1.685), 1.139 (0.883-1.470) and 1.364 (1.092-1.703), respectively. No difference was observed in females. CONCLUSION: High alcohol consumption was associated with increased risk of stroke in both males and females. However, based on change patterns, consistent drinkers and starters were at higher risk of stroke only in males.

Multiple roles and regulatory mechanisms of the transcription factor GATA6 in human cancers.

Cancer is a common type of non-communicable disease, and its morbidity and mortality are rapidly increasing. It is expected to become the largest obstacle to the promotion of global human health in the future. Some transcription factors that play important regulatory roles in embryogenesis and subsequent tissue maintenance can be selectively amplified during tumorigenesis. Due to its high expression in the embryonic endoderm and mesoderm, GATA6 plays a crucial role in the normal development of early human heart, lung, digestive system, adrenal glands, breasts, ovaries, retina, skin, and nervous system. Up to now, overexpression of the GATA6 gene has been shown to play an important role in several cancers, including lung cancer, digestive system tumors, breast cancer, and ovarian cancer. However, the human body is a complex organism, which causes the transcription factor GATA6 to have multiple roles in cancer. In this review, we summarize the multiple roles of transcription factor GATA6 in various cancers and its regulatory mechanisms. The aim is to better understand the relationship between GATA6 gene expression and cancer development and to provide new insights for exploring potential therapeutic targets.

Potential impacts of the 2017 American College of Cardiology/American Heart Association high blood pressure guideline on Chinese adults and how to address them.

BACKGROUND: The current analysis was performed to estimate the percentage and number of Chinese adults with hypertension and the percentage and number of Chinese adults recommended to receive pharmacological antihypertensive treatment according to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) guideline compared with the same parameters according to the 2010 Chinese guideline. METHODS: We used 2011 data from the China Health and Nutrition Survey (CHNS). A total of 12,499 Chinese adults aged ≥18 years with complete blood pressure (BP) values were selected for the present analysis. RESULTS: The crude prevalence rates (95% CI) of hypertension according to the definitions from the 2017 ACC/AHA guideline and the 2010 Chinese guideline were 58.0% (57.2 to 58.9%) and 25.4% (24.7 to 26.2%), respectively. Moreover, the percentage of the participants recommended to take antihypertensive medications were 31.5 and 28.8%, respectively. Among adults who took antihypertensive medications, 88.8% had above-goal BP levels compared to 53.3%. Overall, 613.3 million Chinese adults (aged ≥18 years) met the criteria for hypertension according to the 2017 ACC/AHA guideline, and 267.7 million met the criteria according to 2010 Chinese guideline. An additional 28.4 million (2.7%) Chinese adults were recommended to take antihypertensive medication. CONCLUSIONS: The present analysis revealed that the 2017 ACC/AHA hypertension guideline will result in a substantial increase in the percentage and number of Chinese adults defined as having hypertension and a small increase in the percentage of adults who are recommended to take antihypertensive medications compared to the same parameters based on the 2010 Chinese guideline. More intensive management and antihypertensive medications use are suggested to improve the control rate of hypertension among Chinese adults.

Association of general and abdominal obesity and their changes with stroke in Chinese adults: Results from an 11.8-year follow-up study.

BACKGROUND AND AIMS: Obesity-related diseases play a significant role in the epidemiology of stroke; however, the exact effects of obesity and transitions in obesity status on stroke risk are still unclear. This study was performed to investigate the association of general and abdominal obesity and their changes with stroke in Chinese adults. METHODS AND RESULTS: A total of 26,815 subjects (13,684 men and 13,131 women) aged ≥35 years participated in the study. The association of general and abdominal obesity and their changes with stroke was estimated by Cox proportional hazards models. During a median follow-up period of 11.8 years, 1507 people developed an incident stroke event. The multivariable-adjusted hazard ratios (HRs) (95% CIs) for stroke comparing the highest vs. lowest quartiles of these measurements were 1.276 (1.068-1.524) for BMI, 1.245 (1.035-1.499) for WC, 0.940 (0.786-1.125) for WHR, and 1.221 (1.019-1.464) for WHtR in men. For women, the corresponding values were 1.368 (1.089-1.718), 1.424 (1.119-1.813), 0.971 (0.765-1.232), and 1.341 (1.059-1.699), respectively. C- statistics showed no difference in the predictive value for stroke among various measures of adiposity. Compared with participants who maintained a normal BMI, the HRs for reversed general obesity was 1.272 (95% CI: 1.044-1.550) among men and 1.240 (95% CI: 0.948-1.623) among women. CONCLUSION: Increasing levels of general or abdominal adiposity consistently predict increased risk of stroke, and maintenance of a normal BMI or WC may aid in stroke prevention.

Hospital mortality in acute coronary syndrome: adjustment of GRACE score by D-dimer enables a more accurate prediction in a prospective cohort study.

BACKGROUD: To assess the value of D-dimer and its combination with The Global Registry of Acute Coronary Events (GRACE) score in predicting in-hospital mortality in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI). METHODS: In 5923 ACS patients undergoing PCI, the role of D-dimer and the added value of D-dimer to GRACE score for predicting in-hospital mortality were tested. RESULTS: After multivariable adjustment, D-dimer could significantly predict in-hospital mortality. Also, it could significantly improve the prognostic performance of GRACE score (C-statistic: z = 2.269, p = 0.023; IDI: 0.016, p = 0.032; NRI: 0.291, p = 0.035). CONCLUSION: In patients with ACS undergoing PCI, D-dimer was an independent predictor of in-hospital death. It could also improve the prognostic performance of GRACE score.

Blood pressure predictors of stroke in rural Chinese dwellers with hypertension: a large-scale prospective cohort study.

BACKGROUND: Little was known about the different predictive power of blood pressure (BP) parameters (SBP, systolic BP; mean arterial pressure, MAP; pulse pressure, PP; and diastolic BP, DBP) and stroke incidence. This study's aim was to compare power of BP parameters predict stroke events among rural dwelling Chinese individuals with hypertension. METHOD: A total of 5097 hypertension patients (56.2% women; mean age, 56.3 ± 11.2 years) were included in the prospective cohort study with a median follow-up of 8.4 years. RESULTS: Until the end of the last follow-up, there were 501 onset strokes (310 ischemic, 186 hemorrhagic, and 5 unclassified strokes) among the 5097 participants. The results showed that hazard ratio (HR) (95% confidence interval, 95% CI) with an increment of 5 mmHg were 1.095 (1.070-1.121) for PP, 1.173 (1.139-1.208) for MAP, 1.109(1.089-1.130) for SBP, 1.143(1.104-1.185) for DBP. The SBP indicated the largest ß coefficient in the Cox proportional hazard model for all stroke except PP or MAP, and the SBP revealed slightly higher value than MAP (ßSBP = 0.435, ßMAP = 0.430, P = 0.756). CONCLUSIONS: Both PP and MAP were predictive factors for stroke. The MAP showed a stronger ability to predict stroke events than PP, and slightly inferior to SBP for hypertension patients.

Elevated blood pressure level based on 2017 ACC/AHA guideline in relation to stroke risk in rural areas of Liaoning province.

BACKGROUND: The new ACC/AHA hypertension guideline lower the definition of hypertension from 140/90 mmHg to 130/80 mmHg and eliminate the category of prehypertension thus increasing the prevalence of hypertension. A purpose of this study is to explore the applicability of the new guidelines in rural China. METHODS: In total, 3229 participants aged ≥35 years and free of stroke at baseline were followed for up to 4.8 years during 2012 to 2017 in a rural community-based prospective cohort study of Xifeng County. The hazard ratio (HR) and 95% Confidence interval (CI) of different blood pressure (BP) levels for risk of incident stroke were analyzed by multivariable Cox proportional hazard models. RESULTS: During the follow-up, 81 new strokes occurred among the 3229 participants. Compared with normal BP (Systolic BP (SBP)<120 mmHg and Diastolic BP (DBP)<80 mmHg), stage 2 hypertension (SBP ≥ 140 mmHg or DBP ≥ 90 mmHg) had approximately 2.1 greater risks for stroke (HR: 2.10, 95% CI: 1.13 to 3.91, P = 0.020). However, there was no significant association between elevated (SBP:120-129 mmHg and DBP<80 mmHg), stage1 hypertension (SBP:130-139 mmHg or DBP:80-89 mmHg) and stroke incidence (HR: 0.93, 95% CI: 0.33 to 2.61, P = 0.888; HR: 0.96, 95% CI: 0.46 to 2.02, P = 0.920, respectively). An increase of the SBP by 1-SD increases the risk for stroke by 56% (HR: 1.56, 95%CI: 1.29 to 1.88, P < 0.001). An increase of the SBP by 20 mmHg increases the risk for stroke by 51% (HR: 1.51, 95%CI: 1.27 to 1.80, P < 0.001). CONCLUSIONS: Compared with normal BP, the stage 2 hypertension based on 2017 ACC/AHA guideline significantly increases the risk of stroke incidence, but this association was not observed between elevated, stage1 hypertension and stroke incidence in Chinese rural adults.

Temporal relationship between body mass index and triglyceride-glucose index and its impact on the incident of hypertension.

BACKGROUND AND AIMS: Obesity and insulin levels can influence each other by metabolism. However, their temporal sequences and influence on hypertension are generally unknown, especially in Chinese adults. Recently, some scholars have proposed that triglycerides-glucose index (TyG) is an important indicator of insulin resistance. The study aims to describe the relationship between body mass index (BMI) and TyG index and its impact on hypertension. METHODS AND RESULTS: A total of 4081 adults (56.33% women) without antihypertensive, hypoglycemic or lipid-lowering medications were selected for the present study. Measurements of BMI and TyG index were obtained twice from 2012 to 2017. Cross-lagged panel analysis was used to describe the temporal sequences between BMI and TyG index, and the effect of their temporal relationship patterns on hypertension was explored through mediation analysis. After adjusting for confounding factors (age, sex, ethnicity et al.), the cross-lagged path coefficient from baseline BMI to follow-up TyG (ρ2 = 0.135, P < 0.001) was significantly greater than the path coefficient from baseline TyG to follow-up BMI (ρ1 = 0.043, P < 0.001), and P < 0.001 for the difference between ρ1 and ρ2. Furthermore, the sensitivity analyses between women and men revealed identical findings. In addition, TyG index mediation effect on BMI-hypertension was estimated to be 38.45% (P < 0.001) in total population, 25.24% in women and 57.35% in men. CONCLUSION: These results provided evidence that the temporal relationship between BMI and insulin resistance is reciprocal and a higher BMI precedes hyperinsulinemia in Chinese adults. This relationship plays an essential role in the development of hypertension, while there is a difference between women and men.

Sex difference in the incidence of stroke and its corresponding influence factors: results from a follow-up 8.4 years of rural China hypertensive prospective cohort study.

BACKGROUND: Few studies investigate sex difference in stroke incidence in rural China hypertensive population. METHODS: A total of 5097 hypertensive patients aged ≥35 years (mean age, 56.3 ± 11.2 years; 43.8% men) were included in our analysis with a median follow-up 8.4 years in Fuxin county of Liaoning province in China. Cox proportional hazard models were used to analyze the association between the potential factors and incident stroke. RESULTS: We observed 501 new strokes (310 ischemic, 186 hemorrhagic, and 5 unclassified stroke) during the follow-up. The overall incidence of stroke was 1235.21 per 100,000 person-years; for men, the rates were 1652.51 and 920.80 for women. This sex difference in all stroke can be explained by approximately 25% through age, systolic blood pressure, body mass index, low-density lipoprotein-cholesterol, current smoking, current drinking, antihypertensive drugs, education and physical activity. Subgroup analysis indicated that in hemorrhagic stroke this sex difference was more remarkable (63.89% can be explained). CONCLUSIONS: The incidence of stroke was higher in men than that in women and this difference was partly explained by several traditional cardiovascular risk factors.

Non-traditional lipid profiles associated with ischemic stroke not hemorrhagic stroke in hypertensive patients: results from an 8.4 years follow-up study.

BACKGROUND: Studies have shown that non-traditional lipid profiles have a better association with stroke than traditional blood lipids in clinical applications, other studies have drawn different conclusions. METHODS: This study was a large-scale study with a median follow-up of 8.4 years. The hazard ratio (HR) and 95% Confidence interval (CI) of lipid variables for risk of incident stroke were analyzed by multivariable Cox proportional hazard models. RESULTS: During the follow-up, 502 new strokes (310 ischemic, 187 hemorrhagic, and 5 unclassified strokes) occurred among the 5099 hypertensive patients. Comparing with the lowest quarter, the HR of future ischemic stroke (IS) in the highest were 1.41(95%CI, 1.03-1.92) for TC, 1.60 (95%CI, 1.15-2.22) for TG, 1.03 (95%CI, 0.75-1.42) for HDL-C, 1.77 (95%CI, 1.29-2.44) for LDL-C, 1.42 (95%CI, 1.03-1.94) for non-HDL, 2.09 (95%CI, 1.45-3.00) for TC/HDL, 2.08 (95%CI, 1.46-2.96) for LDL/HDL, 1.86 (95%CI 1.33-2.60) for TG/HDL, respectively. No significant association was observed between lipid-related indicators and hemorrhagic stroke. The results of statistical differences showed that the correlation between LDL/HDL and the risk of ischemic stroke in non-traditional lipids was higher than that of other traditional lipids (P < 0.001), except for LDL (P = 0.056). CONCLUSIONS: We didn't find that HDL was associated with the risk of stroke and all the lipid parameters were not associated with the risk of hemorrhagic stroke. LDL/HDL was associated with a higher risk of ischemic stroke than other lipids and should be considered for clinical diagnosis and future disease prevention.

Value of the fT3/fT4 ratio and its combination with the GRACE risk score in predicting the prognosis in euthyroid patients with acute myocardial infarction undergoing percutaneous coronary intervention: a prospective cohort study.

BACKGROUND: Thyroid hormones deeply influence the cardiovascular system; however, the association between the fT3/fT4 ratio and the clinical outcome in euthyroid patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI) is not well defined. Therefore, the present study aimed to assess the prognostic performance of the fT3/fT4 ratio in predicting the long-term prognosis in euthyroid patients with AMI undergoing PCI. METHODS: In a prospective cohort study with a 1-year follow-up, according to the clinical end point, 953 euthyroid individuals (61.0 ± 11.6; female, 25.8%) were divided into two groups: (1) the survival group (n = 915) and (2) the death group (n = 38). RESULTS: According to Cox regression multivariate analysis, fT4 (HR: 1.249, 95% CI: 1.053-1.480, p = 0.010) and the fT3/fT4 ratio (HR: 3.546, 95% CI: 1.705-7.377, p = 0.001) were associated with an increased risk of 1-year all-cause mortality. The prognostic performance of the fT3/fT4 ratio was similar to the Global Registry of Acute Coronary Events (GRACE) score in predicting 1-year all-cause mortality (C-statistic: z = 0.261, p = 0.794; IDI: -0.017, p = 0.452; NRI: -0.049, p = 0.766), but better than fT4 (C-statistic: z = 2.438, p = 0.015; IDI: 0.053, p = 0.002; NRI: 0.656, p < 0.001). The fT3/fT4 ratio also significantly improved the prognostic performance of the GRACE score (GRACE score vs GRACE score + fT3/fT4 ratio: C-statistic: z = 2.116, p = 0.034; IDI: 0.0415, p = 0.007; NRI: 0.614, p < 0.001). CONCLUSIONS: In euthyroid patients with AMI undergoing PCI, the fT3/fT4 ratio was an independent predictor of 1-year all-cause mortality. Its prognostic performance was similar to the GRACE score, and also improved its prognostic performance (GRACE score vs GRACE score + fT3/fT4 ratio).

Polymorphism of CONNEXIN37 gene is a risk factor for ischemic stroke in Han Chinese population.

BACKGROUND: Stroke has a high fatality and disability rate, and is one of the main burdens to human health. It is thus very important to identify biomarkers for the development of effective approaches for the prevention and treatment of stroke. Connexin37 is an anti-inflammatory cytokine and is involved in chronic inflammation and atherosclerosis. Recent studies have found that CONNEXIN37 gene variations are associated with atherosclerosis diseases, such as coronary heart disease and stroke, but its association with stroke in distinct human populations remains to be determined. We report here the analysis of the association of the single nucleotide polymorphisms (SNPs) of CONNEXIN37 with ischemic stroke in Han Chinese population. METHODS: Two SNPs of CONNEXIN37 gene were analyzed in 385 ischemic stroke patients and 362 hypertension control patients using ligase detection reaction (LDR) method. RESULTS: Logistic regression analysis demonstrated that, AG and GG genotypes of SNP rs1764390 and CC genotype of rs1764391 of CONNEXIN37 were associated with an increased risk of ischemic stroke, and that G allele of rs1764390 is a risk factor for ischemic stroke. Further, we found that SNP rs1764390 and SNP rs1764391 in CONNEXIN37 were associated with ischemic stroke under additive/dominant model, and recessive/dominant model, respectively. CONCLUSION: Our results indicate that CONNEXIN37 gene polymorphism is an ischemic stroke risk factor in Northern Han Chinese.

Predictive Value of Mean Platelet Volume/Platelet Count for Prognosis in Acute Myocardial Infarction.

Increased mean platelet volume (MPV) has been associated with adverse clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). We aim to assess whether MPV/platelet count (MPV/PC) ratio is a useful marker to predict long-term prognosis in patients with STEMI undergoing PCI. Moreover, the prognostic accuracy of MPV/PC ratio is compared with MPV. 962 consecutive patients with STEMI treated with P-PCI were considered. According to the admission MPV/PC values, the population was divided into two groups: high MPV/PC group (n = 320, MPV/PC ≥ 0.055) and low MPV/PC group (n = 642, MPV/PC < 0.055). Multivariate analysis showed that high MPV/PC was an independent predictor of major adverse cardiovascular event (MACE; hazard ratio [HR]: 1.121, 95% confidence interval [CI]: 1.056-1.190, P < 0.01), all-cause mortality (HR: 1.109, 95% CI: 1.016-1.209, P = 0.020), cardiac mortality (HR: 1.141, 95% CI: 1.038-1.253, P = 0.006), nonfatal myocardial reinfarction (HR: 1.148, 95% CI: 1.044-1.262, P = 0.004), and unplanned repeat revascularization (HR: 1.073, 95% CI: 1.007-1.144, P = 0.030), respectively. MPV/PC ratio has good accuracy for predicting MACE (the area under the receiver-operating characteristic curve: 0.764), and the cut-off value was 0.054 with a sensitivity of 0.813 and a specificity of 0.662. The discriminatory performance of MPV/PC ratio was better than MPV for predicting MACE (MPV/PC ratio versus MPV: z = 2.285, P = 0.022), in patients with STEMI undergoing P-PCI. MPV/PC ratio is able to but better than MPV to predict long-term adverse outcomes in patients with STEMI undergoing P-PCI.

Human Cytomegalovirus Increases the Risk of Future Hemorrhagic But Not Ischemic Stroke　- A Nested Case-Control Study.

BACKGROUND: The cause-and-effect relationship between human cytomegalovirus (HCMV) and stroke has not been widely elucidated. We aimed to determine if HCMV infection has an increased risk of future stroke in hypertensive patients in rural areas of China. METHODS AND RESULTS: This was a nested case-control study from a prospective cohort study. A total of 300 newly diagnosed stroke cases with a median follow-up period of 8.4 years and 300 matched controls were selected for the present analysis. Adjusted odds ratio (OR) for stroke associated with HCMV DNA seropositivity was calculated by conditional logistic regression. HCMV DNA was detected in 38 of 300 samples from stroke patients and in 17 of 300 control samples (12.7% vs. 5.7%; P=0.023). Seropositivity for HCMV DNA increased the risk of incident stroke (unadjusted OR, 1.437; 95% confidence interval (CI), 1.023-2.020, P=0.037) and adjustment for other potential cardiovascular confounders only slightly changed the OR (1.464; 95% CI, 1.003-2.137, P=0.048). After controlling for potential cardiovascular confounders, the OR for hemorrhagic stroke associated with HCMV DNA was 1.718 (95% CI, 1.042-2.832), whereas the OR for ischemic stroke was 0.450 (95% CI, 0.142-1.428). CONCLUSIONS: Seropositivity for HCMV DNA was positively associated with total and hemorrhagic but not ischemic stroke, which persisted after controlling for other cardiovascular factors.
