Objective:To explore the relationship between risk perception and health promoting lifestyle profile in population with cardiovascular disease (CVD), and construct a prediction model for clinical screening and targeted intervention.Methods:A cross-sectional survey method was used to select 272 people at moderate and high risk of CVD from the Second Affiliated Hospital of Zhejiang University School of Medicine from March to August 2022. The general information questionnaire, Chinese version of Attitude and Beliefs about Cardiovascular Disease Knowledge and Risk Questionnaire (ABCD-C), and Health Promoting Lifestyle Profile-II (HPLP Ⅱ) were used. Based on multiple regression analysis, a nomogram model for health promoting lifestyle in high-risk CVD population was constructed.Results:Among 272 participants, male 150 cases, female 122 cases, aged (60.58 ± 10.64) years old. The total ABCD-C score was (56.57 ± 5.69), and the total HPLP Ⅱ score was (111.92 ± 12.47). ABCD-C score was significantly positively correlated with HPLP Ⅱ score ( r=0.556, P<0.01). The median of HPLP Ⅱ total score (111 points) was used as the cut-off point for low level of health-promoting lifestyle (≤111 points) and high level of health-promoting lifestyle (>111 points), and used it as the dependent variable, smoking ( OR=0.215, 95% CI 0.104-0.446) was a barrier factor for participants to adopt healthy lifestyle; being married ( OR=14.237, 95% CI 1.963-103.238), having a family average monthly income higher than 5 000 yuan ( OR=4.101, 95% CI 1.369-12.288), higher score of CVD prevention knowledge ( OR=1.660, 95% CI 1.373-2.007), perceived benefits and intention to change physical activity ( OR=1.445, 95% CI 1.255-1.663), perceived benefits and intention to change healthy diet ( OR=1.322, 95% CI 1.058-1.654) were promoting factors. Conclusions:The health-promoting lifestyle of populations at risk for CVD is above-average, influenced by factors such as smoking, marital and economic status, risk attitudes, and beliefs. Utilizing the nomogram model for early screening and targeted risk communication among key populations may contribute to improving their health behavior.

Introduction::Observational studies have revealed an association between waist circumference (WC) and atrial fibrillation (AF). However, it is difficult to infer a causal relationship from observational studies because the observed associations could be confounded by unknown risk factors. Therefore, the causal role of WC in AF is unclear. This study was designed to investigate the causal association between WC and AF using a two-sample Mendelian randomization (MR) analysis.Methods::In our two-sample MR analysis, the genetic variation used as an instrumental variable for MR was acquired from a genome-wide association study (GWAS) of WC (42 single nucleotide polymorphisms with a genetic significance of P <5 × 10 –8). The data of WC (from the Genetic Investigation of ANthropometric Traits consortium, containing 232,101 participants) and the data of AF (from the European Bioinformatics Institute database, containing 55,114 AF cases and 482,295 controls) were used to assess the causal role of WC on AF. Three different approaches (inverse variance weighted [IVW], MR–Egger, and weighted median regression) were used to ensure that our results more reliable. Results::All three MR analyses provided evidence of a positive causal association between high WC and AF. High WC was suggested to increase the risk of AF based on the IVW method (odds ratio [OR] = 1.43, 95% confidence interval [CI], 1.30–1.58, P = 2.51 × 10 -13). The results of MR–Egger and weighted median regression exhibited similar trends (MR–Egger OR = 1.40 [95% CI, 1.08–1.81], P = 1.61 × 10 -2; weighted median OR = 1.39 [95% CI, 1.21–1.61], P = 1.62 × 10 -6). MR–Egger intercepts and funnel plots showed no directional pleiotropic effects between high WC and AF. Conclusions::Our findings suggest that greater WC is associated with an increased risk of AF. Taking measures to reduce WC may help prevent the occurrence of AF.

Objective To design a multisensory supported device and evaluate its effectiveness on preterm infants(born before 34 weeks)during NICU hospitalization.Methods The multisensory supported device is composed of a basement,several soft cushions and an adjustable eye mask.The inner layer of the device comprises of the head and tail boundaries,serves as uterine wall-like circular boundaries.The outer skeleton is equipped with multisensory stimulation modules to provide visual,hearing,and tactile sensory stimulations for premature infants.The study was conducted in a NICU of a tertiary A children specialist hospital in Shanghai,China.The convenience sampling method was used and based on the ratio of 1∶2 between the experimental and the control group in this study.The control group was treated by standard nursing care,while the experiment group was treated with the multisensory supported device in addition to NICU conventional care.All infants were assessed during the week of admission and again at corrected gestational age of 36 weeks.The actigraphy watch which was used for 72 hours continuous record of the activities of study infants,allows the researcher to compare the activity scores,wakefulness and sleep indicators of 2 groups of infants.Results 71 preterm infants were enrolled in the study,and 60 preterm infants completed data collection for study data analysis,including 20 in the experimental group and 40 in the control group.There were no statistical differences in demographic characteristics and clinical status regarding wakefulness,sleep and physical development between the 2 groups in baseline(P＞0.05).At 36 weeks of corrected gestational age,the activity score of the experimental group was(46.61±12.14)points,and that of the control group was(57.33±18.36)points,with statistically significant differences in 2 groups(P=0.024).The total waking time of the experimental group was(384.85±169.42)min,and that of the control group was(492.08±220.45)min,with statistically significant differences in 2 groups(P=0.049).There was no statistical difference in other indicators between 2 groups(P＞0.05).Conclusion The multisensory supported device can reduce high-frequency unpleasant activity as well as frequent wakefulness status,which could promote the sleeping quality of preterm infants.Further studies are needed to verify further effects of the device on premature infants'physical development.

Objective To investigate the preoperative risk factors of occurrence of intra-operative ventricular fibrillation (VF) in patients with acute inferior myocardial infarction undergoing emergency percutaneous coronary intervention(PCI). Methods A retrospective approach was conducted, 572 patients with acute inferior myocardial infarction admitted to Cangzhou City People's Hospital from May 2016 to May 2018 were enrolled, and they were divided into VF group (50 cases) and non-VF group (520 cases) according to whether the intra-operative complication of VF occurred. The clinical data of the two groups of patients were collected, and the related risk factors were analyzed by univariate and multivariate analyses to explore the preoperative risk factors related to VF intra-operative occurrence in patients with acute inferior myocardial infarction undergoing emergency PCI; the receiver operating characteristic (ROC) curve was drawn to evaluate the test efficiencies of all kinds of risk factors. Results The univariate analysis showed that the ratio of Killip > Ⅰ grade, infarct area size/blood potassium concentration (IS/[K]) and symptom onset to balloon dilatation time (SOTBT) in the VF group were significantly higher than those in the non-VF group [Killip > Ⅰ grade:36.5% (19/52) vs. 24.0% (125/520), IS/[K]: 3.2±0.3 vs. 2.5±0.8, SOTBT (hours): 6.3 (2.1, 8.0) vs. 4.6 (1.8, 6.5)], the differences were statistically significant (all P < 0.05); the T wave peak to T end interval/QT interval (Tp-e/QT) and blood potassium level of the VF group were significantly lower than those of the non-VF group [Tp-e/QT: 0.3±0.1 vs. 0.4±0.1; blood potassium (mmol/L): 2.8±0.5 vs. 4.1±1.2, both P < 0.05]. Multivariate logistic regression analysis showed that the SOTBT > 6 hours [odds ratio (OR) = 8.337], Killip >Ⅰ grade (OR = 1.721), hypokalemia (OR = 1.031) and high IS/[K] (OR = 9.167) were independent risk factors for intra-operative occurrence of VF in patients with acute inferior myocardial infarction during emergency PCI (all P < 0.05). ROC curve analysis showed that the area under the ROC curve (AUC) of serum potassium, IS/[K], SOTBT > 6 hours and Killip > Ⅰ grade for predicting the intra-operative occurrence of VF during emergency PCI for patients with acute inferior myocardial infarction had certain values, their AUC were 0.633, 0.837, 0.821, 0.682, respectively, suggesting that IS/[K] and SOTBT > 6 hours had moderate predictive values, and serum potassium, Killip > Ⅰ grade had relatively low predicative values; when the optimal cut-off value of IS/[K] was 2.8, the sensitivity was 85.5% and the specificity was 80.0%. Conclusion SOTBT > 6 hours, Killip > Ⅰ grade, hypokalemia, and high IS/[K] are independent risk factors of intra-operative occurrence of VF in patients with acute inferior myocardial infarction undergoing emergency PCI.

Objective To explore the possible causative factors of appearance of ventricular fibrillation (VF) during emergency percutaneous coronary intervention (PCI) in patients with acute inferior myocardial infarction. Methods Five hundred and seventy two patients with acute inferior myocardial infarction who underwent emergency PCI 24 hours after onset from May 2016 to May 2018 in Cangzhou People's Hospital were enrolled, they were divided into a VF group (52 cases) and a non-VF group (NVF, 520 cases) according to whether VF occurred or not during PCI. The differences in clinical data, characteristics of coronary artery disease and coronary artery score (Gensini score) between the two groups were compared; multivariate Logistic regression analysis was used to analyze the risk factors related to the occurrence of VF during emergency PCI; the receiver operating characteristic curve (ROC) was drawn to evaluate the efficacy of each risk factor. Results There were no statistical significant differences in sex, age, past histories of drinking alcohol, smoking, hypertension, diabetes, previous use of β blockers, aspirin, the peak values at admission of systolic blood pressure, heart rate, creatine kinase isoenzyme (CK-MB) and cardiac troponin I (cTnI), etc between the two groups (all P > 0.05). The proportions of patients with grade 0 blood flow in myocardial infarction thrombolysis (TIMI) before recanalization, with high thrombus load, criminal vessels being right coronary artery (RCA) and proximal segment of RCA, Gensini score in VF group were significantly higher than those in NVF group [TIMI 0: 80.8% (42/52) vs. 58.1% (302/520), high thrombus load: 71.2% (37/52) vs. 58.1% (302/520), criminals being RCA: 84.6% (44/52) vs. 73.7% (383/520), the occlusion site of infarction-related artery (IRA) being the proximal segment of RCA: 61.5% (32/52) vs. 41.2% (214/520), Gensini scores: 93.84±16.48 vs. 61.37±20.01, all P < 0.05]. The multiple logistic regression analysis showed that the risk factors for VF occurrence during emergency PCI for patients with acute inferior myocardial infarction included the criminals being RCA [odds ratio (OR) = 1.967, 95% confidence interval (95% CI) = 1.696-3.015, P =0.032], TIMI blood flow grade 0 before re-canalization (OR = 3.032, 95%CI = 1.248-3.675, P = 0.043), the occlusion site of infarction-related artery (IRA) being the proximal segment of RCA (OR = 2.288, 95%CI = 1.458-3.895, P =0.024), Gensini score (OR = 6.558, 95%CI = 2.168-13.359, P = 0.001] and high thrombus load (OR = 1.781, 95%CI =1.016-3.017, P = 0.033); they all were risk factors of occurrence of ventricular fibrillation during emergency PCI in patients with acute inferior myocardial infarction (all P < 0.05). ROC curve analysis showed that TIMI blood flow grade 0 before re-canalization, Gensini score and higher thrombus load had certain predictive value for VF occurrence during emergency PCI for acute inferior wall myocardial infarction; the area under ROC curve (AUC) was 0.613, 0.869 and 0.605, and 95% CI was 0.540-0.687, 0.787-0.969 and 0.521-0.675, the P value was 0.007, 0.000 and 0.012, respectively, suggesting that Gensini score had moderate predictive value for intra-operative VF, while the predictive values of TIMI blood flow grade 0 before re-canalization and higher thrombus load were relatively low. When the Gensini score had an optimal cutoff value of 96.50, the sensitivity was 85.50% and the specificity was 81.20%. Conclusion The risk factors of VF occurrence in emergency PCI for patients with acute inferior myocardial infarction are criminal vessel RCA, TIMI blood flow grade 0 before re-canalization, IRA occlusion site being proximal segment of RCA, Gensini score and high thrombus load; pre-recanalization TIMI blood flow grade 0, Gensini score and higher thrombus load all have certain predictive value for the occurrence of VF in emergency PCI for acute inferior myocardial infarction.

Objective To investigate the prognostic risk factors of patients with acute inferior myocardial infarction and intra-operative occurrence of ventricular fibrillation (VF) when undergoing emergency percutaneous coronary intervention (PCI). Methods The data of 52 patients with acute inferior myocardial infarction treated in Cangzhou City People's Hospital from May 2016 to May 2018 were retrospectively analyzed, and they were divided into poor prognosis group (19 cases) and good prognosis group (33 cases) according to whether cardiovascular events occurred during 1 year of follow-up. The patients' gender, age, smoking or not, histories of diabetes, hypertension, hyperlipidemia, and the results of well performed color echocardiography within recent 3 days, such as left ventricular ejection fraction (LVEF), cardiac infarction size (IS), and coronary Gensini score were recorded in the two groups; the indicators with statistical significance in univariate analysis were included in the multivariate logistic regression analysis to screen out the prognostic risk factors of patients with acute inferior wall myocardial infarction undergoing emergency PCI and occurrence of intra-operative VF; Receiver operating characteristic (ROC) curve was drawn to evaluate the values of coronary Gensini score and IS in predicting intraoperative occurrence of VF in patients with acute inferior wall myocardial infarction undergoing emergency PCI. Results During 1-year follow-up, 19 of 52 patients with acute inferior myocardial infarction occurred VF, the incidence being 36.5%. The univariate analysis showed that the IS and Gensini score in poor prognosis group were significantly higher than those in the good prognosis group [IS: (3.2±0.2)% vs. (2.5±0.4)%, Gensini score: 98.8±12.5 vs. 85.7±8.4, both P < 0.05], the LVEF level was significantly lower in the poor prognosis group than that in the good prognosis group (0.37±0.08 vs. 0.46±0.11, P < 0.05). The multivariate Logistic regression analysis showed that IS [odds ratio (OR) = 5.016] and coronary Gensini score (OR = 2.415) were the risk factors of occurrence of cardiovascular events after surgery in patients with acute inferior myocardial infarction and intra-operative VF when undergoing PCI (P < 0.05). The ROC curve analysis showed that IS and coronary Gensini scores had certain predictive values for the prognosis of patients with acute inferior myocardial infarction and occurrence of intra-operative VF when undergoing emergency PCI, the area under the ROC curve (AUC) was 0.863 and 0.597, respectively, indicating that IS had a medium predictive value, while the value of coronary Gensini score was lower, when the IS optimal cut off value was 3.0, the sensitivity was 89.4% and the specificity was 88.0%. Conclusion High IS and Gensini score are the risk factors of prognosis of patients with acute inferior myocardial infarction and intra-operative occurrence of VF when undergoing emergency PCI.

Objective To assess and compare the incidence,clinical characteristics,treatment,and prognosis of acute heart failure patients from different grades hospitals in Beijing.Methods In this prospective internet prognosis registered study (Beijing AHF Registry),a total of 3 335 consecutive patients admitted to 14 emergency departments in Beijing from January 1st 2011 to September 23rd 2012 were enrolled.According to hospital grade,these patients were divided into two groups,349 patients were from secondary hospitals,and 2 956 patients were from tertiary hospitals.Results Among the 3 335 patients,the medium age was 71 (58,79) years,and male accounted for 53.16％.The most common underlying disease were coronary disease (43.27％),hypertension (17.73％),cardiomyopathy (16.07％) etc.The average treatment time in Emergency Department was 66.82 h.The emergency department mortality rate was 3.81％ (127 cases).The 30-day and 1-year cumulative all-cause mortality were 15.3％ and 32.27％,respectively.The 30-day and 1-year cumulative all-cause readmission were 15.64％ and 46.89％,respectively.Compared with patients in tertiary hospitals,patients in secondary hospitals had more onset acute heart failure patients (63.64％ vs.49.93％),shorter emergency department treatment time (12 h vs.41 h),lower discharge rate (3.43％ vs.37.45％) and emergency department mortality(1.58％ vs.4.09％).Compared with those in tertiary hospitals,1-year cumulative all-cause mortality (25.6％ vs.33.2％),cardiovascular disease mortality (20.2％ vs.26.0％),aggravated heart failure mortality (22.4％ vs.28.8％) were lower in secondary hospitals.Following propensity score matching,compared to tertiary hospitals,patients in secondary hospitals showed lower utilization rate of beta-blockers and ACEFARB (4.51％ vs.28.17％,1.41％ vs.9.58％),except the pironolactone.Conclusion Acute heart failure in emergency department is associated with a high mortality rate and readmission rate.There is still a big gap between guidelines recommend medication current treatments for acute heart failure.

Objective To compare the image quality and radiation dose of CTA of the kidney in patients using routine CT and the spectral imaging combination of different scanning protocols with the adaptive statistical iterative reconstruction 2.0 algorithm (ASIR 2.0). Methods A total of 90 patients who had undergone a CTA of the kidney were divided into three groups (A, B and C), with 30 patients in each group. Group A underwent a routine CT examination, and the scan parameters are:120 kVp, 30 to 650 mA, rotation time 0.5 s/r, scan FOV 50 cm × 50 cm;while groups B and C underwent spectral imaging protocol 1 and 2, the scan parameters of spectral imaging protocol 1 and 2 are:rapid dual kVp (80-140 kVp) switching in 0.25 ms, 375 mA and 360 mA, rotation time 0.7 s/r and 0.6 s/r, scan FOV 36 cm × 36 cm and 32 cm × 32 cm, respectively. All images were reconstructured using ASIR 2.0. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of all images were calculated when the kidney CTA was completed. Each subjective image evaluation used a 5-point scoring method and was conducted by two independent radiologists. The CT dose index (CTDIvol) and dose-length product (DLP) were recorded, and the mean value was calculated. The DLP was converted to the effective dose (ED). All data were compared with Kruskal-Wallis test and one-way ANOVA. Results The energy level of 49 to 56 keV was found to provide the best CNR for displaying CTA of the kidney. There were significant differences in CT values, noise, SNR, CNR and subjective score between groups B, C and A (P<0.05), and there was no significant differences in CT values, noise, SNR, CNR and subjective score between groups B and C (P>0.05). There were significant differences in ED among groups A, B and C (P<0.05), and the ED of groups A, B and C were (8.2±1.2), (5.2± 0.9) and (4.4 ± 0.7) mSv, respectively. Conclusion Spectral imaging with different scanning protocols can more effectively reduce the radiation dose than the routine CT scan mode for a kidney CTA while still maintaining diagnostic image quality, and protocol 2 of spectral imaging in our study is recommended.
