RESUMO
OBJECTIVE: This study aimed to compare the efficacy and safety of adalimumab (ADA) versus tocilizumab (TCZ) in patients with Takayasu arteritis (TAK). METHODS: This was a randomized, controlled, open-label study. Forty patients with active and severe TAK were enrolled. They were treated with ADA (n = 21) combined with glucocorticoids (GCs) and methotrexate (MTX) or TCZ (n = 19) combined with GCs and MTX. The planned follow-up duration was 12 months. The primary end point was the efficacy rate (ER) at 6 months. The secondary endpoints included ER at 9 and 12 months, relapse rate, GC tapering, adverse effects, and life quality changes during treatment. RESULTS: In the intention-to-treat (ITT) population, the ER at 6 months was higher in the ADA group (85.71% vs 52.63%, P= 0.02). A similar direction of effect was noted in the per-protocol set (89.47% vs 62.50%, P= 0.06). The percentages of patients who achieved a GC dose of ≤ 10 mg/day at 6 months were similar between the ADA and TCZ groups (47.37% vs 43.75%, P= 0.83). The ERs at 9 and 12 months were similar between the two groups (P> 0.05). During the first 12 months of treatment, the relapse rate and adverse event incidence were comparable between the two groups (ADA vs TCZ: 9.52% vs 10.53%, P= 0.96; 38.10% vs 47.37%, P= 0.55, respectively). CONCLUSION: ADA combined with GCs and MTX may be more efficacious than TCZ combined with GCs and MTX among patients with active and severe TAK. TRIAL REGISTRATION: Clinicaltrials.gov; NCT04300686.
RESUMO
OBJECTIVE: To compare the treatment efficacy and safety of tofacitinib (TOF) versus methotrexate (MTX) in Takayasu arteritis (TAK). METHODS: Fifty-three patients with active disease from an ongoing prospective TAK cohort in China were included in this study. Twenty-seven patients were treated with glucocorticoids (GCs) and TOF, and 26 patients were treated with GCs with MTX. The observation period was 12 months. Complete remission (CR), inflammatory parameter changes, GCs tapering and safety were assessed at the 6th, 9th and 12th month. Vascular lesions were evaluated at the 6th and 12th month, and relapse was analysed during 12 months. RESULTS: The CR rate was higher in the TOF group than in the MTX group (6 months: 85.19% vs 61.54%, p=0.07; 12 months: 88.46% vs 56.52%, p=0.02). During 12 months' treatment, patients in the TOF group achieved a relatively lower relapse rate (11.54% vs 34.78%, p=0.052) and a longer median relapse-free duration (11.65±0.98 vs 10.48±2.31 months, p=0.03). Average GCs dose at the 3rd, 6th and 12th month was lower in the TOF group than that in the MTX group (p<0.05). A difference was not observed in disease improvement or disease progression on imaging between the two groups (p>0.05). Prevalence of side effects was low in both groups (3.70% vs 15.38%, p=0.19). CONCLUSION: TOF was superior to MTX for CR induction, a tendency to prevent relapse and tapering of the GCs dose in TAK treatment. A good safety profile for TOF was also documented in patients with TAK.

OBJECTIVE: To investigate the utility of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) in assessing disease activity in Takayasu arteritis (TA). METHODS: Ninety-one patients with TA were recruited from a Chinese cohort. Clinical data, acute-phase reactants and 18F-FDG-PET/CT findings were simultaneously recorded. The value of using 18F-FDG-PET/CT to identify active disease was evaluated, using ESR as a reference. Disease activity assessment models were constructed and concordance index (C-index), net reclassification index (NRI), and integrated discrimination index (IDI) were evaluated to compare the benefits of the new modes with ESR and the Kerr score. RESULTS: In total, 64 (70.3%) cases showed active disease. Higher levels of ESR and CRP, and lower IL-2 receptor (IL-2R) levels were observed in active cases. 18F-FDG-PET/CT parameters measured by determining the standard uptake value (SUV), including SUVmean, SUVratio1, SUVratio2, sum of SUVmean and sum of SUVmax, were significantly higher in active disease groups. The C-index threshold of ESR to indicate active disease was 0.78 (95% CI: 0.69, 0.88). The new activity assessment model combining ESR, sum of SUVmean and IL-2R showed significant improvement in C-index over the ESR method (0.96 vs 0.78, P < 0.01; NRI 1.63, P < 0.01; and IDI 0.48, P < 0.01). The new model also demonstrated modest superiority to the Kerr score assessment (0.96 vs 0.87, P = 0.03; NRI 1.19, P < 0.01; and IDI 0.33, P < 0.01). CONCLUSIONS: A novel 18F-FDG-PET/CT-based method that involves combining the sum of SUVmean with ESR score and IL-2R levels demonstrated superiority in identifying active TA compared with conventional methods.

OBJECTIVE: This study aimed to describe pulmonary high-resolution CT (HRCT) findings in Takayasu arteritis (TA) and to determine possible causes. METHODS: A total of 243 TA patients were enrolled from a prospective cohort after excluding patients with other pulmonary disorders or incomplete data. Patients were divided into two groups: those with normal lung HRCT and those with abnormal lung HRCT. Clinical characteristics were compared between groups and binary logistic regression analysis was applied to identify possible causes of the lung lesions. Follow-up HRCT (obtained in 64 patients) was analysed to study changes in pulmonary lesions after treatment. RESULTS: Of the 243 patients, 107 (44.0%) had normal lung HRCT while 136 (56.0%) had abnormal lung HRCT, including stripe opacity (60.3%), nodules (44.9%), patchy opacity (25.0%), pleural thickening (15.4%), pleural effusion (10.3%), ground-glass opacity (8.1%), pulmonary infarction (6.6%), mosaic attenuation (4.4%), bronchiectasis (3.7%) and pulmonary oedema (2.2%). Patients with abnormal HRCT were significantly more likely to have type II arterial involvement (25% vs 12.2%, P = 0.04), pulmonary arterial involvement (PAI; 21.3% vs 5.6%, P < 0.001), pulmonary hypertension (20.6% vs 8.4%, P = 0.01) and abnormal heart function (27.9% vs 7.6%, P < 0.001). Logistic regression analysis demonstrated that PAI, worsened heart function and age were associated with presence of pulmonary lesions. Pulmonary infarction, pleural effusion and patchy opacities improved partially after treatment. CONCLUSION: Pulmonary lesions are not rare in patients with TA. Age, PAI and worsened heart function are potential risk factors for presence of pulmonary lesions in TA.

BACKGROUND: H type hypertension is defined as homocysteine (Hcy) ≥ 10 µmol/L in combination with primary hypertension. Studies demonstrated that the existence of hyperhomocysteine (HHcy) in hypertensive exacerbates the poor outcome of cardiocerebral incidents. This study was to investigate the current epidemic situation of H type hypertension and determine the risk factors in order to find intervention targets for H type hypertensives. METHODS: We conducted a cross-sectional study using cluster sampling design in Shanghai, China from July 2019 and April 2020. 23,652 patients with primary hypertension were enrolled in this study. Their medical information was recorded, and the level of Hcy concentrations and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphisms were detected. RESULTS: In total, 22,731 of 23,652 patients were recorded. The mean age was 68.9 ± 8.6 y and 43% were men. 80.0% of the enrolled patients had H type hypertension. The frequency of allele T was 40.9%, and the proportions of the CC, CT, and TT genotypes were 36.1%, 46.0%, and 17.9%, respectively. Compared with the TT genotype, the plasma Hcy concentration levels were lower in patients with the CC/CT genotype (18.96 ± 13.48 µmol/L vs. 13.62 ± 5.20/14.28 ± 5.36, F = 75.04, p < 0.01). The risk for H type hypertension was higher in elderly people. Men had ~ 5.55-fold odds of H type hypertension compared with women. Patients with CT genotype and TT genotype had ~ 1.36- and ~ 2.76-fold odds of H type hypertension compared with those with CC genotype, respectively. Smoking and diabetes were not significantly associated with H type hypertension. CONCLUSIONS: The prevalence of H type hypertension in patients with primary hypertension was 80.0%, which was higher than the 75% found in prior report in China. Age, gender, and MTHFR C677T polymorphisms rather than smoking and diabetes were independently associated with H type hypertension.

BACKGROUND & AIMS: Esophagectomy is the standard treatment for early-stage esophageal squamous cell carcinoma (EESCC), but patients who undergo this procedure have high morbidity and mortality. Endoscopic submucosal dissection (ESD) is a less-invasive procedure for treatment of EESCC, but is considered risky because this tumor frequently metastasizes to the lymph nodes. We aimed to directly compare outcomes of patients with EESCC treated with ESD vs esophagectomy. METHODS: We performed a retrospective cohort study of patients with T1a-m2/m3, or T1b EESCCs who underwent ESD (n = 322) or esophagectomy (n = 274) from October 1, 2011 through September 31, 2016 at Zhongshan Hospital in Shanghai, China. The primary outcome was all-cause mortality at the end of follow up (minimum of 6 months). Secondary outcomes included operation time, hospital stay, cost, perioperative mortalities/severe non-fatal adverse events, requirement for adjuvant therapies, and disease-specific mortality and cancer recurrence or metastasis at the end of the follow up period. RESULTS: Patients who underwent ESD were older (mean 63.5 years vs 62.3 years for patients receiving esophagectomy; P = .006) and a greater proportion was male (80.1% vs 70.4%; P = .006) and had a T1a tumor (74.5% vs 27%; P = .001). A lower proportion of patients who underwent ESD had perioperative mortality (0.3% vs 1.5% of patients receiving esophagectomy; P = .186) and non-fatal severe adverse events (15.2% vs 27.7%; P = .001)-specifically lower proportions of esophageal fistula (0.3% of patients receiving ESD vs 16.4% for patients receiving esophagectomy; P = .001) and pulmonary complications (0.3% vs 3.6%; P = .004). After a median follow-up time of 21 months (range, 6-73 months), there were no significant differences between treatments in all-cause mortality (7.4% for ESD vs 10.9%; P = .209) or rate of cancer recurrence or metastasis (9.1% for ESD vs 8.9%; P = .948). Disease-specific mortality was lower among patients who received ESD (3.4%) vs patients who patients who received esophagectomy (7.4%) (P = .049). In Cox regression analysis, depth of tumor invasion was the only factor associated with all-cause mortality (T1a-m3 or deeper vs T1a-m2: hazard ration, 3.54; P = .04). CONCLUSION: In a retrospective study of patients with T1am2/m3 or T1b EESCCs treated with ESD (n = 322) or esophagectomy (n = 274), we found lower proportions of patients receiving ESD to have perioperative adverse events or disease specific mortality after a median follow up time of 21 months. We found no difference in overall survival or cancer recurrence or metastasis in patients with T1a or T1b ESCCs treated with ESD vs esophagectomy.

Associations between ferritin and insulin sensitivity have been described in recent studies. The possible association showed conflicting results by sex and menopausal status. We aimed to investigate the cross-sectional association of ferritin levels with insulin resistance and ß-cell function. A total of 2518 participants (1033 men, 235 pre-menopausal women and 1250 post-menopausal women) were enrolled from the Changfeng Study. A standard interview was conducted, as well as anthropometric measurements and laboratory analyses, for each participant. The serum ferritin level was measured using electrochemiluminescence immunoassay. Insulin resistance and ß-cell function indices were derived from a homeostasis model assessment. The results showed that the serum ferritin levels were 250·4 (sd 165·2), 94·6 (sd 82·0) and 179·8 (sd 126·6) ng/ml in the men, pre-menopausal and post-menopausal women, respectively. In fully adjusted models (adjusting for age, current smoking, BMI, waist:hip ratio, systolic blood pressure, diastolic blood pressure, TAG, HDL-cholesterol, LDL-cholesterol, log urine albumin:creatinine ratio, leucocytes, alanine aminotransferase, aspartate aminotransferase and γ-glutamyl transpeptidase), serum ferritin concentrations are significantly associated with insulin resistance in men and post-menopausal females, and the null association was observed in pre-menopausal females. Interestingly, an increased ß-cell function associated with higher ferritin was observed in post-menopausal participants, but not in male participants. In conclusion, these results suggested that elevated serum ferritin levels were associated with surrogate measures of insulin resistance among the middle-aged and elderly male and post-menopausal women, but not in pre-menopausal women.

BACKGROUND: We investigate whether non-high-density lipoprotein cholesterol (non-HDL-C) provides a better estimate of cardiovascular risk than other lipid profiles in normotensive and euglycemic middle-aged and elderly adults. METHODS: A total of 512 males and 958 females were enrolled from the Changfeng Study. A standard interview, anthropometric measurements and laboratory analyses were performed for each participant. Bilateral carotid intima-media thicknesses (CIMTs) were measured using ultrasonography, and the presence of carotid plaques was assessed. RESULTS: The mean values of non-HDL-C were 3.4 ± 0.8 mmol/l and 3.6 ± 0.9 mmol/l for male and female subjects, respectively. Compared with female subjects with non-HDL-C in the first quartile, female subjects with non-HDL-C in the fourth quartile had 1.317-fold increased risks for carotid plaques after adjusting for conventional cardiovascular disease (CVD) risk factors and increasing quartiles of all lipid levels. Non-HDL-C was positively associated with the CIMT after adjusting for CVD risk factors in female subjects (ß = 0.062, P = 0.034). CONCLUSIONS: These results suggest that non-HDL-C is independently associated with carotid atherosclerosis in normotensive and euglycemic females.

To assess the effectiveness of cyclophosphamide (CYC) versus methotrexate (MTX) for active Takayasu's arteritis (TA). The current study was based on a cohort of TA at Zhongshan Hospital, Fudan University. TA was diagnosed using the 1990 American College of Rheumatology criteria. Fifty-eight subjects receiving induction treatment with CYC (n = 46) or MTX (N = 12) were included in the analysis. Effectiveness and toxicity were assessed in all 58 cases. Clinical remission was defined as: Kerr score reduction to ≤ 1 and glucocorticoids (GC) treatment at a dose of ≤ 0.2 mg/kg/day (≤ 15 mg/day) at the end of the 6th month. At the baseline, the CYC group had higher Kerr scores (60.9% vs. 16.7% at ≥3, p = 0.044), higher ESR (55 ± 52 vs. 25 ± 22 mm/H, p = 0.048), ITAS_ESR (12.4 ± 1.7 vs. 9.1 ± 1.1 mg/L, p = 0.043). The 6-month clinical remission rate was 71.7% vs. 75% in the CYC and MTX group, respectively. In the CYC group, a significant decrease was observed in ESR (55 ± 52 vs. 25 ± 48 mm/H, p = 0.008), hs-CRP (27 ± 23 vs. 6.9 ± 6.6 mg/L, p = 0.007), ITAS (11.7 ± 2.2 vs. 7.0 ± 1.5, p = 0.048), and ITAS_ESR (7.1 ± 2.0 vs. 12.4 ± 1.7, p = 0.033). However, no significant reductions in these measures were demonstrated in the MTX group. Whole-body contrast enhanced magnetic resonance angiography (MRA) revealed significant radiologic improvement (wall enhancement scores: 4.2 ± 2.3 vs. 10.3 ± 3.8, p = 0.032) in the CYC group, but not in the MTX group. No severe adverse events occurred in any subject. Cyclophosphamide could be a better choice than methotrexate as induction treatment for patients with more severe Takayasu's arteritis.

Postmenopausal women are at increased risk of CVD: the increased serum ferritin level may be involved in the pathogenesis. The aim of the present study is to investigate the relationship of ferritin and carotid atherosclerosis in postmenopausal women. A total of 1178 postmenopausal women (mean age, 60·8 years) were enrolled from the Changfeng Study. A standard interview, anthropometric measurements and laboratory analyses were performed for each participant. Bilateral CIMT (carotid intima-media thickness) were measured using ultrasonography, and the presence of carotid plaques was assessed. Serum ferritin was measured using electrochemiluminescence immunoassay. The results showed that serum ferritin was 181·9 (sd 65·8) ng/ml in the postmenopausal women. Multivariate, linear, stepwise regression analysis demonstrated that age (standardised ß = 0·233, P< 0·001), alanine transaminase (standardised ß = 0·194, P< 0·001), log homeostasis model assessment index for insulin resistance (standardised ß = 0·181, P< 0·001), TAG (standardised ß = 0·083, P= 0·003), Hb (standardised ß = 0·080, P= 0·004) and PPG (2-h glucose levels following a 75-g oral glucose challenge) (standardised ß = 0·079, P= 0·004) were independently associated with serum ferritin. Compared with the ferritin level of subjects in the first quartile, that in the fourth quartile had greater CIMT, and higher prevalence of carotid plaque. After adjusting for conventional CVD risk factors, Hb, leucocytes, log urine albumin:creatinine ratio and liver function, the ferritin level of postmenopausal women in the fourth quartile had a 1·587-fold increased risk of carotid plaques relative to those in the lowest quartile. In conclusion, these results suggest that serum ferritin is independently and positively associated with carotid atherosclerosis in postmenopausal women and that ferritin may be implicated in atherosclerosis.

Characteristics of heart failure with preserved ejection fraction (HFPEF) have not yet been fully understood. The objectives of this pilot study are to detect protein expression profile in the sera of HFPEF patients, and to identify potential biomarkers for the disease. Five hundred and seven proteins were detected in the sera of healthy volunteers and patients with either HFPEF or hypertension using antibody microarrays (three in each group). The results showed that the serum concentrations of 17 proteins (e.g. angiogenin, activin A and artemin) differed considerably between HFPEF and non-HFPEF patients (hypertensive patients and healthy controls), while a protein expression pattern distinct from that in non-HFPEF patients was associated with HFPEF patients. The up-regulation of angiogenin in both HFPEF patients with LVEF ≥50% (P = 0.004) and a subset of HFPEF patients with LVEF = 41-49% (P < 0.001) was further validated in 16 HFPEF patients and 16 healthy controls. Meanwhile, angiogenin distinguished HFPEF patients from controls with a mean area under the receiver operating characteristic curve of 0.88 (P < 0.001) and a diagnostic cut-off point of 426 ng/ml. Moreover, the angiogenin levels in HFPEF patients were positively correlated with Lg(N-terminal pro-B-type natriuretic peptide, NT-proBNP) (P < 0.001). In addition, high angiogenin level (≥426 ng/ml) was a predictor of all-cause death within a short-term follow-up duration, but not in the longer term of 36 months. This pilot study indicates that the aforementioned 17 potential biomarkers, such as angiogenin, may hold great promise for both diagnosis and prognosis assessment of HFPEF.

BACKGROUND: The role of serum 25-hydroxyvitamin D (25 (OH) D) in atherogenesis is unclear. We investigated whether the 25 (OH) D is independently associated with the carotid intima-media thickness (CIMT) and carotid plaques in normotensive and euglycemic postmenopausal women. METHODS: A total of 671 normotensive and euglycemic postmenopausal women (mean age, 58.8 years) were enrolled from the Changfeng Study. A standard interview, anthropometrics measurements and laboratory analyses were performed for each participant. Bilateral CIMTs were measured using ultrasonography, and the presence of carotid plaques was assessed. The serum 25 (OH) D was measured using electrochemiluminescence immunoassay. RESULTS: Serum 25 (OH) D was 43.6 ± 18.2 nmol/L in the postmenopausal women. Compared with subjects with 25 (OH) D in the first, second and third quartiles, subjects with 25 (OH) D in the fourth quartile had decreased CIMT and prevalence of carotid plaque (0.684 ± 0.009 mm vs 0.719 ± 0.009 mm, 0.708 ± 0.009 mm and 0.709 ± 0.009 mm; 10.8% vs 19.0%, 14.8% and 16.8%, respectively). After adjusting for conventional CVD risk factors, PTH, liver and renal function, postmenopausal women with 25 (OH) D in the fourth quartile still had lower CIMT than those in the first, second and third quartiles (p = 0.039) and the subjects in the fourth quartile had a 0.421-fold decreased risk of carotid plaques relative to those in the lowest quartile (95% confidence interval 0.209 to 0.848). CONCLUSIONS: These results suggest serum 25 (OH) D is independently and inversely associated with carotid atherosclerosis in postmenopausal women with normal blood pressure and normal glucose tolerance.

AIMS: Heart failure with preserved ejection fraction (HFpEF) is a devastating health issue although limited knowledge is available for its pathogenesis and therapeutics. Given the perceived involvement of mitochondrial dysfunction in HFpEF, this study was designed to examine the role of mitochondrial dynamics in the etiology of HFpEF. METHOD AND RESULTS: Adult mice were placed on a high fat diet plus l-NAME in drinking water ('two-hit' challenge to mimic obesity and hypertension) for 15 consecutive weeks. Mass spectrometry revealed pronounced changes in mitochondrial fission protein Drp1 and E3 ligase FBXL4 in 'two-hit' mouse hearts. Transfection of FBXL4 rescued against HFpEF-compromised diastolic function, cardiac geometry, and mitochondrial integrity without affecting systolic performance, in conjunction with altered mitochondrial dynamics and integrity (hyperactivation of Drp1 and unchecked fission). Mass spectrometry and co-IP analyses unveiled an interaction between FBXL4 and Drp1 to foster ubiquitination and degradation of Drp1. Truncated mutants of FBXL4 (Delta-Fbox) disengaged interaction between FBXL4 and Drp1. Metabolomic and proteomics findings identified deranged fatty acid and glucose metabolism in HFpEF patients and mice. A cellular model was established with concurrent exposure of high glucose and palmitic acid as a 'double-damage' insult to mimic diastolic anomalies in HFpEF. Transfection of FBXL4 mitigated 'double-damage'-induced cardiomyocyte diastolic dysfunction and mitochondrial injury, the effects were abolished and mimicked by Drp1 knock-in and knock-out, respectively. HFpEF downregulated sarco(endo)plasmic reticulum (SR) Ca2+ uptake protein SERCA2a while upregulating phospholamban, RYR1, IP3R1, IP3R3 and Na+-Ca2+ exchanger with unaltered SR Ca2+ load. FBXL4 ablated 'two-hit' or 'double-damage'-induced changes in SERCA2a, phospholamban and mitochondrial injury. CONCLUSION: FBXL4 rescued against HFpEF-induced cardiac remodeling, diastolic dysfunction, and mitochondrial injury through reverting hyperactivation of Drp1-mediated mitochondrial fission, underscoring the therapeutic promises of FBXL4 in HFpEF.

OBJECTIVE: Qiliqiangxin (QLQX) capsule- a traditional Chinese medicine used for treating heart failure (HF), can modulate inflammatory cytokines in rats with myocardial infarction. However, its immune-regulating effect on dilated cardiomyopathy (DCM) remains unknown. The aim of this study was to investigate whether QLQX has a unique regulatory role in the imbalance of pro- and anti-inflammatory cytokines in patients with DCM. METHODS: The QLQX-DCM is a randomized- double-blind trial conducted at 24 tertiary hospitals in China. A total of 345 patients with newly diagnosed virus-induced DCM were randomly assigned to receive QLQX capsules or placebo while receiving optimal medical therapy for HF. The primary endpoints were changes in plasma inflammatory cytokines and improvements in left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDd) over the 12-month treatment. RESULTS: At the 12-month follow-up, the levels of IFN-γ, IL-17, TNF-α, and IL-4 decreased significantly, while the level of IL-10 increased in both groups compared with baselines (all P<0.0001). Furthermore-these changes, coupled with improvements in LVEF, NT-proBNP and New York Heart Association (NYHA) functional classification, excluding the LVEDd in the QLQX group, were greater than those in the placebo group (all P<0.001). Additionally, compared with placebo, QLQX treatment also reduced all-cause mortality and rehospitalization rates by 2.17% and 2.28%, respectively, but the difference was not statistically significant. CONCLUSION: QLQX has the potential to alleviate the imbalance of inflammatory cytokines in patients with DCM, potentially leading to further improvements in cardiac function when combined with anti-HF standard medications.
RESUMO
BACKGROUND: The National Chest Pain Center Program (NCPCP) is a nationwide, quality enhancement program aimed at raising the standard of care for patients experiencing acute chest pain in China. The benefits of chest pain center (CPC) accreditation on acute coronary syndrome have been demonstrated. However, there is no evidence to indicate whether CPC accreditation improves outcomes for patients with acute aortic dissection (AAD). METHODS: We conducted a retrospective observational study of patients with AAD from 1671 hospitals in China, using data from the NCPCP spanning the period from January 1, 2016 to December 31, 2022. The patients were divided into 2 groups: pre-accreditation and post-accreditation admissions. The outcomes examined included in-hospital mortality, misdiagnosis, and Stanford type A AAD surgery. Multivariate logistic regression was employed to explore the relationship between CPC accreditation and in-hospital outcomes. Furthermore, we stratified the hospitals based on their geographical location (Eastern/Central/Western regions) or administrative status (provincial/non-provincial capital areas) to assess the impact of CPC accreditation on AAD patients across various regions. RESULTS: The analysis encompassed a total of 40,848 patients diagnosed with AAD. The post-accreditation group exhibited significantly lower rates of in-hospital mortality and misdiagnosis (12.1% vs. 16.3%, P < 0.001 and 2.9% vs. 5.4%, P < 0.001, respectively) as well as a notably higher rate of Stanford type A AAD surgery (61.1% vs. 42.1%, P < 0.001) compared with the pre-accreditation group. After adjusting for potential covariates, CPC accreditation was associated with substantially reduced risks of in-hospital mortality (adjusted OR 0.644, 95% CI 0.599-0.693) and misdiagnosis (adjusted OR 0.554, 95% CI 0.493-0.624), along with an increase in the proportion of patients undergoing Stanford type A AAD surgery (adjusted OR 1.973, 95% CI 1.797-2.165). Following CPC accreditation, there were significant reductions in in-hospital mortality across various regions, particularly in Western regions (from 21.5 to 14.1%). Moreover, CPC accreditation demonstrated a more pronounced impact on in-hospital mortality in non-provincial cities compared to provincial cities (adjusted OR 0.607 vs. 0.713). CONCLUSION: CPC accreditation is correlated with improved management and in-hospital outcomes for patients with AAD.

OBJECTIVE: To establish the normal ranges for plasma N-terminal-pro-B-type natriuretic peptide (NT-proBNP) of middle-aged and elderly ( ≥ 40 years) healthy subjects in China. METHODS: A total of 5133 subjects (2170 men and 2963 women) from the cohort of Shanghai Heart Health Study (SHHS) were included in this study. Plasma NT-proBNP was measured by electrochemiluminescence immunoassay. The reference values (2.5th- 97.5th quartiles) were determined using both empiric and quantile regression methods. RESULTS: Plasma NT-proBNP values were higher in women than in men at all respective age groups (all P < 0.01) , and natural log-transformed NT-proBNP values increased in proportion with age for both genders and there was a lineal correlation between natural log-transformed NT-proBNP values and age (all P < 0.01) . Quantile regression derived normal reference values for NT-proBNP in male were 4.5-86.8 ng/L in the 40-44 years old group, 5.4-108.5 ng/L in the 45-49 years old group, 6.6-135.5 ng/L in the 50-54 years old group, 7.9-169.4 ng/L in the 55-59 years old group, 9.6-211.7 ng/L in the 60-64 years old group, 11.7-264.6 ng/L in the 65-69 years old group, 14.2-330.7 ng/L in the 70-74 years old group, and 18.1-429.2 ng/L in the ≥ 75 years old group. The reference values in female for NT-pro-BNP in respective age group were 8.5-141.8 ng/L, 10.4-166.6 ng/L, 12.8-195.7 ng/L, 15.7-229.9 ng/L, 19.3-270.1 ng/L, 23.7-317.3 ng/L, 29.1-372.8 ng/L, and 35.7-451.9 ng/L. CONCLUSION: This study preliminarily establishes the normal ranges of plasma NT-proBNP in middle-aged and elderly ( ≥ 40 years) Chinese.

BACKGROUND: Dyskalemia is a mortality risk factor in patients with heart failure (HF). HYPOTHESIS: We described the prevalence of dyskalemia, and clinical outcomes by serum potassium (sK) levels, in Chinese patients hospitalized for HF. METHODS: In this secondary analysis of the prospective China National Heart Failure Registry, adult patients hospitalized between January 1, 2013 and June 30, 2015 who had at least one baseline sK measurement were followed for up to 3 years after discharge. The use of renin-angiotensin-aldosterone system inhibitors at baseline and clinical outcomes during follow-up were compared among sK groups. RESULTS: Among 6950 patients, 5529 (79.6%) had normokalemia (sK >3.5-5.0 mmol/L), 1113 (16.0%) had hypokalemia (sK 0-3.5 mmol/L), and 308 (4.4%) had hyperkalemia (sK >5.0 mmol/L). Baseline characteristics that were most common in patients with hyperkalemia than those with hypo- and normokalemia included older age, HF with reduced ejection fraction, New York Heart Association Class III/IV status, hypertension, and chronic kidney disease. Use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) differed across sK groups (p = .0001); reported in 64.1%, 63.4%, and 54.5% of patients with hypo-, normo-, and hyperkalemia, respectively. Overall, 26.6%, 28.6%, and 36.0% of patients with hypo-, normo-, and hyperkalemia had rehospitalization for worsened HF, or cardiovascular mortality; p = .0057 for between-group comparison. CONCLUSIONS: Patients with hyperkalemia received ACEIs or ARBs for HF treatment at baseline less frequently than those with hypo- or normokalemia, and had worse prognoses. This warrants further investigation into effective hyperkalemia management in HF.

BACKGROUND: No randomized trial has been conducted to compare different vasodilators for treating no-reflow during primary percutaneous coronary intervention (PCI) for ST-segment elevation acute myocardial infarction. METHODS: The prospective, randomized, 2-center trial was designed to compare the effect of 3 different vasodilators on coronary no-reflow. A total of 102 patients with no-reflow in primary PCI were randomized to receive intracoronary infusion of diltiazem, verapamil, or nitroglycerin (n = 34 in each group) through selective microcatheter. The primary end point was coronary flow improvement in corrected thrombolysis in myocardial infarction frame count (CTFC) after administration of the drug. RESULTS: Compared with that of the nitroglycerin group, there was a significant improvement of CTFC after drug infusion in the diltiazem and verapamil groups (42.4 frames vs 28.1 and 28.4 frames, P < .001). The improvement in CTFC was similar between the diltiazem and verapamil groups (P = .9). Compared with the nitroglycerin group, the diltiazem and verapamil groups had more complete ST-segment resolution at 3 hours after PCI, lower peak troponin T level, and lower N-terminal pro-B-type natriuretic peptide levels at 1 and 30 days after PCI. After drug infusion, the drop of heart rate and systolic blood pressure in the verapamil group was greater than that in the diltiazem and nitroglycerin groups. CONCLUSION: Intracoronary infusion of diltiazem or verapamil can reverse no-reflow more effectively than nitroglycerin during primary PCI for acute myocardial infarction. The efficacy of diltiazem and verapamil is similar, and diltiazem seems safer.

BACKGROUND: Adiponectin is reported to relate with cardiovascular diseases, we sought to examine whether adiponectin is associated with disease progression of heart failure from hypertension in rats in comparison with other known biomarkers and echocardiographic parameters. Spontaneously hypertensive rats (SHR, n = 35), aged 1 month, were used and followed up to 18 months. High frequency echocardiography was performed both at baseline and every 3 months thereafter. Moreover, serum levels of N-terminal pro-natriuretic peptide (NT-proBNP) and interleukin-6 (IL-6) as well as serum level and tissue expression of adiponectin were determined at the same time as echocardiography. RESULTS: The results clearly demonstrated time-dependent progression of hypertension and heart dysfunction as evidenced by gradually increased left ventricular mass index, NT-proBNP, IL-6 as well as gradually decreased cardiac function as assessed by echocardiography. Meanwhile, tissue and serum adiponectin decreased from 3 months and reached plateau until 12 months in parallel with decreasing of cardiac diastolic function. Thereafter, adiponectin levels increased prior to occurrence of systolic dysfunction. Adiponectin concentration is inversely related with NT-proBNP, IL-6 and E/E' (correlation coefficient (r) = -0.756 for NT-proBNP, p < 0.001, -0.635 for IL-6, p = 0.002, and -0.626 for E/E', p = 0.002, respectively) while positively correlated with E/A and E'/A' (r = 0.683 for E/A, p = 0.001, 0.671 for E'/A', p = 0.001, respectively). No difference for adiponectin distribution among visceral adipose tissues was found. CONCLUSION: Adiponectin through its biphasic serum level is a useful biomarker during transition from diastolic dysfunction to systolic dysfunction.
