ABSTRACT
Background: Restoring and maintaining sinus rhythm in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) has been studied in clinical trials to reduce symptoms and improve quality of life. Limited data exist on the effectiveness of rate or rhythm control therapy in these patients. Methods: Consecutive patients with AF and ACS or referred for PCI were prospectively recruited in Fuwai Hospital during 2017-2020. The primary endpoints were all-cause death and major adverse cardiovascular and cerebrovascular events (MACCEs), including cardiovascular mortality, myocardial infarction, ischemic stroke, non-central nervous system embolism and ischemia-driven revascularization. Kaplan-Meier curves and Cox regressions were performed to evaluate the association between rhythm/rate control and subsequent outcomes. For the primary endpoints, we used the Benjamini-Hochberg correction for multiple comparisons. Results: A total of 1499 patients with AF and ACS or undergoing PCI were included, with a median follow-up of 34.7 months. Compared to non-rate control, rate control strategy reduced the risk of subsequent MACCEs (adjusted HR, 0.320; 95 % CI 0.220-0.466; p <0.001; *p <0.002) and all-cause death (adjusted HR, 0.148; 95 % CI 0.093-0.236; p <0.001; *p <0.002). Similar trends were observed across all predefined subgroups (p <0.001). In the final multivariate model, rhythm control was not associated with a lower subsequent MACCEs but significantly improved all-cause mortality compared to non-rhythm control (adjusted HR, 0.546; 95 % CI 0.313-0.951; p =0.033; *p =0.044). Conclusions: In this real-world study, rate control strategy was associated with lower risk of MACCEs and all-cause death in AF and ACS or undergoing PCI. Besides, management with rhythm control strategy may improve all-cause mortality.
ABSTRACT
BACKGROUND: We aimed to explore the impact of adherence to Life's Simple 7 (LS7) metrics on risk of obstructive sleep apnea (OSA), and the impact of inflammation on the association, in adults in the United States. METHODS: Data from 13,825 community-dwelling adults aged ≥ 20 years recruited in the National Health and Nutrition Examination Surveys (NHANES) 2005-2008, 2015-2018 was analyzed. The LS7 score was calculated based on the AHA definition of LS7 metrics. The diagnosis of OSA was based on self-reported symptoms of sleep disturbance using a standard questionnaire. The Multivariable Apnea Prediction (MAP) Index score was also calculated to assess the risk of OSA. Log-binominal regression and negative binomial regression were performed to estimate the associations between LS7 and OSA and MAP index, with odds ratios (ORs) and prevalence ratios (PRs) and their 95% confidence intervals (CIs) calculated. Mediation analysis was performed to estimate the mediating effects of inflammatory indicators on the associations. RESULTS: A total of 4473 participants (32.4%) had OSA, and the mean MAP index was 0.39. In fully adjusted log-binominal regression models, with total score < 6 as the reference, the ORs (95% CIs) for risk of OSA were 0.90 (0.73, 1.10), 0.76 (0.65, 0.89), 0.78 (0.64, 0.95), and 0.45 (0.38, 0.54) for total score = 6, total score = 7, total score = 8, and total score > 8, respectively (P for trend < 0.001). When LS7 score was analyzed as a continuous variable, each 1-point increase in LS7 score was associated with a 15% decrease in OSA risk (P < 0.001). In negative binominal regression models, the adjusted PRs (95% CIs) for the MAP index were 0.93 (0.90, 0.97), 0.87 (0.84, 0.91), 0.80 (0.77, 0.84), and 0.55 (0.53, 0.57) for total score = 6, total score = 7, total score = 8, and total score > 8, respectively (P for trend < 0.001). For each 1-point increase in LS7 score, the risk of OSA decreased by 13% (P < 0.001). Consistent results were observed in subgroup analysis. Mediation analysis indicated that inflammatory factors, including blood cell count, neutrophil count, and C-reactive protein, positively mediated the association of LS7 with OSA, with a mediation proportion of 0.022 (P = 0.04), 0.02 (P = 0.04), and 0.02 (P = 0.02), respectively. CONCLUSIONS: In a nationally representative sample of US adults, adherence to LS7 metrics was independently associated with reduced OSA risk. Inflammation plays a mediating role in the association between LS7 and OSA.

BACKGROUND: The benefit-risk profile of direct oral anticoagulants (DOAC) therapy in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF) has not been well established yet. This study aimed to evaluate the efficacy and safety of DOAC compared with vitamin K antagonists (VKA) in patients with HCM and AF. METHODS: PubMed, EMBASE, the Cochrane Library, and clinicaltrials.gov were searched to identify studies comparing DOAC with VKA in patients with HCM and AF. The primary endpoint was thromboembolic events. The relative risks and standard errors were pooled by random-effect models using the generic inverse variance method. RESULTS: Seven observational studies involving 9395 patients were included in this meta-analysis. Compared to the VKA group, the DOAC group displayed a similar risk of thromboembolic events [RR (95%CI): 0.93 (0.73-1.20), p = 0.59] and ischemic stroke [RR (95%CI): 0.65 (0.33-1.28), p = 0.22]. The incidence of major bleeding was comparable between the two groups [RR (95%CI): 0.75 (0.49-1.15), p = 0.19]. Meanwhile, DOAC therapy was superior to VKA therapy in reducing the incidences of all-cause death [RR (95%CI): 0.44 (0.35-0.55), p < 0.001], cardiovascular death [RR (95%CI): 0.41 (0.22-0.75), p = 0.004], and intracranial hemorrhage [RR (95%CI): 0.42 (0.24-0.74), p = 0.003]. CONCLUSION: In patients with HCM and AF, DOAC therapy was similar to VKA therapy in reducing the risk of thromboembolic events, without increasing bleeding risk. In addition, the DOAC group displayed significant advantages in reducing mortality and intracranial hemorrhage compared with the VKA group. Further randomized controlled trials are needed to provide more evidence for DOAC therapy in this population.
ABSTRACT
Animal experiments have shown that high exposure to ethylene oxide (EO) can cause multiple system damages including the renal system. Recent studies have reported associations between exposure to EO and cancer, dyslipidemia, diabetes, and cardiovascular disease. However, the impact of exposure to EO on the prevalence and prognosis of chronic kidney disease (CKD) in humans is scarcely investigated. The study was designed to investigate the associations between EO exposure and incidence and prognosis of CKD among 2900 US adults. Exposure to EO was measured by detecting the levels of hemoglobin adducts of EO (HbEO). The diagnosis of CKD was made according to an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 and/or a urinary albumin-to-creatinine ratio (UACR) > 30 mg/g. Prognosis of CKD was assessed based on the evaluation system initiated by KDIGO that consists of eGFR and UACR. Survey-weighted generalized linear models and proportional odds models were constructed to assess the associations between HbEO and prevalence and prognosis of CKD, with odds ratios (ORs) and proportional odds ratios (PORs) and their 95% confidence intervals (CIs) reported, respectively. Restricted cubic spline (RCS) function was performed to depict the correlation between HbEO and CKD. The weighted median (interquartile range) of HbEO was 31.3 (23.1-60.3) pmol/g Hb. A total of 491 participants (16.9%) were diagnosed with CKD, and 153 participants (5.31%) were identified to be at high or very high risk. Referred to the first tertile of HbEO, the adjusted ORs (95% CIs) for CKD in the second and third tertile were 1.46 (0.85, 2.50) and 1.69 (1.00, 2.85), and the adjusted PORs (95% CIs) for prognosis of CKD in the second and third tertile were 1.37 (0.94, 1.99) and 1.58 (1.10, 2.26). When HbEO was analyzed as a continuous variable, the adjusted OR (95% CI) for CKD and POR (95% CI for prognosis of CKD were 1.24 (0.97, 1.58) and 1.22 (1.01, 1.47), respectively. RCS analysis revealed a non-linear positive correlation between HbEO and prevalence of CKD (P for nonlinearity < 0.05). Subgroup analysis indicated smoking status had a significant impact on this association, which remained significant among never smokers but lost significance among smokers. Among US adults, increased EO exposure was independently related to increased CKD prevalence and poor CKD outcomes, which was established in never smokers but not among ever smokers.

BACKGROUND: Early risk stratification with simple biomarkers is essential in patients with non-ST segment-elevation myocardial infarction (NSTEMI). OBJECTIVE: This study aimed to evaluate the association between plasma big endothelin-1 (ET-1) level and the SYNTAX score (SS) in patients with NSTEMI. METHODS: A total of 766 patients with NSTEMI undergoing coronary angiography were recruited. Patients were divided into three groups: low SS (≤22), intermediate SS (23-32), and high SS (>32). Spearman correlation, smooth curve fitting, logistic regression, and receiver operating characteristic (ROC) curve analysis were performed to evaluate the association between plasma big ET-1 level and the SS. A p-value <0.05 was considered statistically significant. RESULTS: There was a significant correlation between the big ET-1 and the SS (r=0.378, p<0.001). The smoothing curve indicated a positive correlation between the plasma big ET-1 level and the SS. The ROC curve analysis showed that the area under the curve was 0.695 (0.661-0.727) and the optimal cutoff of plasma big ET-1 level was 0.35pmol/l. Logistic regression showed that elevated big ET-1 was an independent predictor of intermediate-high SS in patients with NSTEMI, whether entered as a continuous variable [OR (95% CI): 1.110 (1.053-1.170), p<0.001] or as a categorical variable [OR (95% CI): 2.962 (2.073-4.233), p<0.001]. CONCLUSION: In patients with NSTEMI, the plasma big ET-1 level was significantly correlated with the SS. Elevated plasma big ET-1 level was an independent predictor for intermediate-high SS.
FUNDAMENTO: A estratificação de risco precoce com biomarcadores simples é essencial em pacientes com infarto do miocárdio sem supradesnivelamento do segmento ST (IAMSSST). OBJETIVO: Este estudo tem o objetivo de avaliar a associação entre nível de big endotelina-1 plasmática (ET-1) e o escore SYNTAX (SS) em pacientes com IAMSSST. MÉTODOS: Foram recrutados 766 pacientes com IAMSSST que passaram por angiografia coronária. Os pacientes foram divididos em três grupos: SS baixo (≤22), SS intermediário (23-32), e SS alto (>32). A correlação de Spearman, o ajuste de curva suave, a regressão logística, e a análise de curva característica de operação do receptor (ROC) foram realizados para avaliar a associação entre o nível de big ET-1 plasmática e o SS. Um p-valor <0.05 foi considerado estatisticamente significativo. RESULTADOS: Foi identificada uma correlação significativa entre a big ET-1 e o SS (r=0,378, p<0,001). A curva suavizada indicou uma correlação positiva entre o nível de big ET-1 plasmática e o SS. A análise de curva ROC demonstrou que a área sob a curva foi de 0,695 (0,661-0,727) e o ponto de corte ideal do nível de big ET-1 plasmática foi de 0,35 pmol/l. A regressão logística demonstrou que a big ET-1 elevada era um preditor independente de SS intermediário a alto em pacientes com IAMSSST, seja como variável contínua [RC (IC 95%: 1,110 (1,053-1,170), p<0,001] ou como variável categórica [RC (IC 95%: 2,962 (2,073-4,233), p<0,001]. CONCLUSÃO: Em pacientes com IAMSSST, o nível de big ET-1 plasmática estava significativamente correlacionado ao SS. O nível de big ET-1 plasmática elevado foi um preditor independente para SS intermediário a alto.

ABSTRACT
BACKGROUND AND AIMS: Stress-induced hyperglycemia (SIH) generally occurs in critical illness. Recently, glycemic gap (GAP) has been considered to be a superior indicator of SIH. However, data on the association between GAP and prognosis in ST-segment elevation myocardial infarction (STEMI) is limited. This observational study aimed to estimate the prognostic value of GAPmean, defined as the difference between mean blood glucose level (MGL) within 24 h after admission and A1c-derived average glucose (ADAG), in patients with acute STEMI. METHODS: A total of 4952 patients with acute STEMI were included in the final analysis, and they were divided into four groups according to GAPmean quartiles and diabetes mellitus (DM). The primary outcomes were all-cause mortality and major adverse cardiovascular events (MACEs). Cox proportional hazards regression analysis and net reclassification improvement (NRI) analysis were performed. RESULTS: At 30 days of follow-up, 324 (6.5%) deaths and 569 (11.5%) MACEs occurred. With the elevation of GAPmean, the incidence of all-cause mortality (4.0%, 5.6%, 6.5%, and 10.1%) and MACEs (7.3%, 9.6%, 11.4%, and 17.7%) significantly increased. Receiver operating characteristic curve analysis demonstrated that GAPmean was superior to admission blood glucose (ABG) and GAPadm (defined as the difference between ABG and ADAG) to detect adverse outcomes. Multivariate Cox regression analysis revealed that elevated GAPmean was independently associated with all-cause death and MACEs. With the first quartile as a reference, the hazards ratios (HRs) for all-cause death in the second, third, and fourth quartiles were 1.49 (95% CI 1.02-2.18), 1.58 (95% CI 1.09-2.30), and 2.11 (95% CI 1.48-3.02), respectively, and the HRs for MACEs were 1.40 (95% CI 1.05-1.86), 1.60 (95% CI 1.21-2.11), and 2.17 (95% CI 1.66-2.83), respectively, which were independent of DM status. Continuous NRI analysis revealed that GAPmean significantly improved risk stratification for all-cause mortality and MACEs by 21.6% and 19.8%, respectively. CONCLUSIONS: The glycemic gap between MGL within 24 h after admission and ADAG was independently associated with 30-day all-cause mortality and MACEs in patients with acute STEMI, which was not affected by DM status. Further, the glycemic gap provided incremental accuracy in the risk stratification of STEMI.

Background: This study aimed to evaluate the association between plasma big ET-1 levels and long-term outcomes in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). Methods: A total of 930 patients were enrolled and followed up for a median duration of 2.3 years. According to the optimal cutoff of big ET-1 for predicting all-cause death, these patients were divided into two groups. The primary endpoints were all-cause death and net adverse clinical events (NACE). The secondary endpoints included cardiovascular death, major adverse cardiovascular events (MACE), BARC class ≥ 3 bleeding, and BARC class ≥ 2 bleeding. Cox regressions were performed to evaluate the association between big ET-1 and outcomes. Results: Based on the optimal cutoff of 0.54 pmol/l, 309 patients (33.2%) had high big ET-1 levels at baseline. Compared to the low big ET-1 group, patients in the high big ET-1 group tended to have more comorbidities, impaired cardiac function, elevated inflammatory levels, and worse prognosis. Univariable and multivariable Cox regressions indicated that big ET-1 ≥ 0.54 pmol/l was associated with increased incidences of all-cause death [HR (95%CI):1.73 (1.10-2.71), p = 0.018], NACE [HR (95%CI):1.63 (1.23-2.16), p = 0.001], cardiovascular death [HR (95%CI):1.72 (1.01-2.92), p = 0.046], MACE [HR (95%CI):1.60 (1.19-2.16), p = 0.002], BARC class ≥ 3 [HR (95%CI):2.21 (1.16-4.22), p = 0.016], and BARC class ≥ 2 bleeding [HR (95%CI):1.91 (1.36-2.70), p < 0.001]. Subgroup analysis indicated consistent relationships between the big ET-1 ≥ 0.54 pmol/l and the primary endpoints. Conclusion: Elevated plasma big ET-1 levels were independently associated with increased risk of all-cause death, NACE, cardiovascular death, MACE, BARC class ≥ 3 bleeding, and BARC class ≥ 2 bleeding in patients with AF and ACS or undergoing PCI.
ABSTRACT
This study aims to evaluate the predictive values of the HAS-BLED, ORBIT, ATRIA, REACH, PARIS, and PRECISE-DAPT scores in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) who received both anticoagulant and antiplatelet therapy. 930 patients were consecutively recruited and followed up for 1 year. The primary endpoints were BARC class ≥3 bleeding and BARC class ≥2 bleeding. BARC class ≥3 bleeding occurred in 36 patients(3.9%), while BARC class ≥2 bleeding was seen in 134 patients (14.4%). The predictive performance of the HAS-BLED score for BARC class ≥3 bleeding was unsatisfactory (c-statistic = 0.575). The discrimination of the ATRIA, ORBIT, PARIS, and PRECISE-DAPT scores was also low-to-moderate. The REACH score was useless in bleeding risk stratification for this population. Multivariable logistic regression indicated that previous bleeding events and hemoglobin were two independent predictors of BARC class ≥3 bleeding. Compared to the HAS-BLED score, the model constructed by previous bleeding events and hemoglobin displayed a significant improvement in bleeding risk prediction [c-statistics: 0.704 vs. 0.575 (p = .008), NRI = 0.662,IDI = 0.049]. In patients with AF and ACS or undergoing PCI who received anticoagulant+antiplatelet therapy, the HAS-BLED, ORBIT, ATRIA, REACH, PARIS, and PRECISE-DAPT scores displayed only low-to-moderate performance in predicting BARC class≥3 bleeding. Future studies are required to develop more reliable scoring systems for bleeding risk evaluation in this population.

BACKGROUND: This study aims to validate the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria in Chinese patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) who received both oral anticoagulants (OAC) and antiplatelet therapy (APT). METHODS: 930 consecutive patients with AF and ACS or undergoing PCI receiving both OAC and APT were recruited and followed up for 1 year. The primary endpoint was BARC type 3 or 5 bleeding. The secondary endpoints included BARC type 2, 3, or 5 bleeding, TIMI major bleeding, TIMI major or minor bleeding, and major adverse cardiovascular events (a composite of all-cause death, stroke, non-central nervous system embolism, myocardial infarction, definite or probable stent thrombosis, and target vessel revascularization). Cox regressions were performed to evaluate the association between the ARC-HBR score and outcomes. Discrimination was evaluated through analysis of the receiver operating characteristic (ROC) curves, net reclassification improvement (NRI), and integrated discrimination improvement (IDI). RESULTS: Compared to patients with no HBR other than OAC, patients with HBR besides OAC tended to have more comorbidities and worse outcomes. The ARC-HBR score was significantly associated with the primary and secondary endpoints, both as a continuous variable and as a categorical variable. The ARC-HBR score performed better than the HAS-BLED score (c-statistic: 0.692 vs. 0.575, NRI = 0.313, IDI = 0.061) and the PRECISE-DAPT score (c-statistic: 0.692 vs. 0.616, NRI = 0.393, IDI = 0.049). CONCLUSIONS: In patients with AF and ACS or undergoing PCI receiving both OAC and APT, the ARC-HBR score was a significant predictor of 1-year bleeding and ischemic endpoints. The ARC-HBR score performed better than the HAS-BLED score and the PRECISE-DAPT score in BARC type 3 or 5 bleeding prediction.

This study aimed to evaluate the predictive performance of the REACH, PARIS, BleeMACS, and PRECISE-DAPT scores in Chinese patients undergoing coronary drug-eluting stent (DES) implantation. A total of 1911 patients undergoing coronary DES implantation were consecutively recruited and followed up for 1 year. The primary endpoints were BARC type 3 or 5 bleeding and BARC type 2,3, or 5 bleeding. The BleeMACS score and the PRECISE-DAPT score were significantly associated with 1-year incidence of BARC type 3 or 5 bleeding, but not BARC type 2, 3, or 5 bleeding. The discrimination of the PRECISE-DAPT score was moderate for BARC type 3 or 5 bleeding (c-statistic = 0.633), while those of the REACH (c-statistic = 0.533), PARIS (c-statistic = 0.553), and BleeMACS scores (c-statistic = 0.613) were relatively low. However, the analysis of c-statistic, NRI, and IDI detected no significant discrimination improvement of the PRECISE-DAPT score for BARC type 3 or 5 bleeding compared to the other three scores. The calibrations of the PRECISE-DAPT and BleeMACS scores were modest (Hosmer-Lemeshow test p > .05). Decision curve analysis indicated net benefit of the PRECISE-DAPT score in bleeding risk evaluation. In conclusion, the PRECISE-DAPT score performed moderately in predicting BARC type 3 or 5 bleeding, while the discriminative capacities of the REACH, PARIS, BleeMACS scores were relatively low in patients undergoing DES implantation. But no significant discrimination improvement of the PRECISE-DAPT score compared to the other scores could be detected. Further studies are required to develop standardized bleeding risk scores for this population.

PURPOSES: The POPular Risk Score (PRiS), a pharmacogenetic-driven algorithm consisting of CYP2C19 genotype, platelet reactivity, and clinical risk factors, is developed to evaluate ischemic risk and guide dual antiplatelet therapy (DAPT). This study aimed to evaluate the efficacy and safety of DAPT in accordance with the PRiS in patients undergoing drug-eluting stent (DES) implantation. METHODS: A total of 1757 patients recruited in this cohort study were divided into four groups according to the PRiS and type of P2Y12 receptor inhibitor treatment at discharge. The primary endpoint was major adverse cardiovascular events (MACE, a composite of cardiovascular death, myocardial infarction, stroke, definite or probable stent thrombosis, and target vessel revascularization) during 1-year follow-up. The safety endpoints were defined by Bleeding Academic Research Consortium (BARC) criteria as major bleeding (BARC 3a, 3b, 3c, and 5) and clinically relevant bleeding (BARC 2, 3a, 3b, 3c, and 5). RESULTS: Among 1046 patients with PRiS < 2 and 711 patients with PRiS ≥ 2, 34.2% and 38.3% of them were treated with ticagrelor, respectively. The PRiS ≥ 2 was an independent predictor for the 1-year incidence of MACE (HR(95%CI): 2.09 (1.37-3.20), p = 0.001). Multivariable Cox regression indicated that in the PRiS ≥ 2 group, ticagrelor was superior to clopidogrel in reducing the risk of MACE (HR(95%CI): 0.53 (0.29-0.98), p = 0.042), without increasing the bleeding risk. On the other hand, in the PRiS < 2 group, clopidogrel treatment was related to a remarkably lower rate of BARC class ≥ 2 bleeding (HR(95%CI): 0.39 (0.20-0.72), p = 0.003), but comparable incidences of MACE and BARC class ≥ 3 bleeding during 1-year follow-up. Similar associations between P2Y12 receptor inhibitors and 1-year endpoints in the PRiS < 2 and PRiS ≥ 2 group could also be identified in propensity score-weighted analysis and propensity score-matched analysis. CONCLUSION: Tailored DAPT based on the PRiS could assist in improving the prognosis of patients undergoing DES implantation. Further randomized controlled trials are required to provide more evidence for PRiS-guided DAPT.

Background: Early risk stratification of patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI) has relevant implication for individualized management strategies. The CHA 2 DS 2 -VASc and GRACE ACS risk model are well-established risk stratification systems. We aimed to assess their prognostic performance in AF patients with ACS or PCI. Methods: Consecutive patients with AF and ACS or referred for PCI were prospectively recruited and followed up for 3 years. The primary endpoint was major adverse cardiovascular and cerebrovascular events (MACCEs), including cardiovascular mortality, myocardial infarction, ischemic stroke, systemic embolism and ischemia-driven revascularization. Results: Higher CHA 2 DS 2 -VASc (HR [hazard ratio] 1.184, 95% CI 1.091-1.284) and GRACE at discharge score (HR 1.009, 95% CI 1.004-1.014) were independently associated with increased risk of MACCEs. The CHA 2 DS 2 -VASc (c-statistics: 0.677) and GRACE at discharge (c-statistics: 0.699) demonstrated comparable discriminative capacity for MACCEs (p = 0.281) while GRACE at admission provided relatively lower discrimination (c-statistics: 0.629, p vs. CHA 2 DS 2 -VASc = 0.041). For predicting all-cause mortality, three models displayed good discriminative capacity (c-statistics: 0.750 for CHA 2 DS 2 -VASc, 0.775 for GRACE at admission, 0.846 for GRACE at discharge). A significant discrimination improvement of GRACE at discharge compared to CHA 2 DS 2 -VASc was detected (NRI = 45.13%). Conclusions: In the setting of coexistence of AF and ACS or PCI, CHA 2 DS 2 -VASc and GRACE at discharge score were independently associated with an increased risk of MACCEs. The GRACE at discharge performed better in predicting all-cause mortality.
ABSTRACT
BACKGROUND AND AIMS: The aim of this study was to evaluate the association between body mass index (BMI) and mortality in atrial fibrillation (AF) patients with and without diabetes mellitus (DM). METHODS AND RESULTS: A total of 1991 AF patients were enrolled and divided into two groups according to whether they have DM at recruitment. Baseline information was collected and a mean follow-up of 1 year was carried out. The primary outcome was defined as all-cause mortality with the secondary outcomes including cardiovascular mortality, stroke and major adverse events (MAEs). Univariable and multivariable Cox regression were performed to estimate the association between BMI and 1-year outcomes in AF patients with and without DM. 309 patients with AF (15.5%) had comorbid DM at baseline. Patients with DM were more likely to have cardiovascular comorbidities, receive relevant medications but carry worse 1-year outcomes. Multivariable Cox regressions indicated that elevated BMI was related with reduced risk of all-cause mortality, cardiovascular mortality and major adverse events. Compared to normal weight, overweight [HR (95% CI): 0.548 (0.405-0.741), p < 0.001] and obesity [HR (95% CI): 0.541 (0.326-0.898), p = 0.018] were significantly related with decreased all-cause mortality for the entire cohort. Remarkably reduced all-cause mortality in the overweight [HR (95% CI): 0.497 (0.347-0.711), p < 0.001] and obesity groups [HR (95% CI): 0.405 (0.205-0.800), p = 0.009] could also be detected in AF patients without DM, but not in those with DM. CONCLUSION: Elevated BMI was associated with reduced mortality in patients with AF. This association was modified by DM. The obesity paradox confined to AF patients without DM, but could not be generalized to those with DM.

Cytochrome P450 (CYP) 2C19 genotype is closely associated with the metabolism and efficacy of clopidogrel, thereby having an important impact on clinical outcomes of patients with acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). This study aimed to evaluate the efficacy and safety of CYP2C19 genotype-guided antiplatelet therapy in patients with ACS or undergoing PCI. PubMed, EMBASE, the Cochrane Library and clinicaltrials.gov were searched to identify randomized controlled trials (RCTs) comparing CYP2C19 genotype-guided antiplatelet therapy with conventional therapy in patients with ACS or undergoing PCI. Eight RCTs involving 6708 patients were included in this meta-analysis. CYP2C19 genotype-guided antiplatelet therapy was slightly superior to the conventional antiplatelet therapy in reducing the risk of MACE [RR(95%CI): 0.71(0.51-0.98), p = .04]. Meanwhile, the genotype-guided therapy group had significantly lower incidence of myocardial infarction [RR(95%CI): 0.56(0.40-0.78), p < .01], but similar risk of all-cause mortality, cardiovascular mortality, stent thrombosis, urgent revascularization and stroke compared to the conventional therapy group. Incidences of major/minor bleeding and major bleeding were comparable between the two groups. In patients with ACS or undergoing PCI, CYP2C19 genotype-guided antiplatelet therapy displayed benefit over conventional antiplatelet therapy in reducing the risk of MACE and myocardial infarction, without increasing bleeding risk. Further RCTs are needed to provide more evidences for CYP2C19 genotype-guided antiplatelet therapy.

BACKGROUND: Elevated body mass index (BMI) is related with reduced mortality in various cardiovascular diseases. HYPOTHESIS: Gender-specific association between BMI and mortality exists in atrial fibrillation (AF). METHODS: In this multicenter observational study with a mean follow-up of 1 year, a total of 1991 AF patients were enrolled and divided into two groups based on the gender. The primary endpoint was all-cause mortality while the secondary endpoints were defined as cardiovascular mortality, stroke, and major adverse events during 1-year follow-up. Cox regression was performed to identify the association between BMI and clinical outcomes according to gender. RESULTS: Female patients with AF tended to be older (P = .027) and thinner (P < .001) than male patients with AF. They were more likely to have heart failure, hyperthyroidism, and valvular AF (all P < .05), but less likely to have coronary artery disease and prior myocardial infarction (all P < .01). Multivariate analysis revealed that overweight (HR(95%CI): 0.55(0.41-0.75), P < .001) and obese patients (HR(95%CI): 0.56(0.34-0.94), P = .028) were associated with significant lower all-cause mortality compared with normal weight patients for the entire cohort. Similar association between elevated BMI and reduced all-cause mortality were only identified in female patients with AF (overweight vs normal weight: HR(95%CI): 0.43(0.27-0.70); obesity vs normal weight: HR(95%CI): 0.46(0.22-0.97)), but not in male patients with AF. CONCLUSION: This study indicates that overweight and obesity were related with improved survival in patients with AF. The association between elevated BMI and reduced mortality was dependent on gender, which was only significant in female patients, rather than male patients.

OBJECTIVE: To evaluate the effect of angiotensin-converting enzyme inhibitor (ACEI)/angiotensin II receptor blocker (ARB) therapy on the prognosis of patients with atrial fibrillation (AF). METHODS: A total of 1, 991 AF patients from the AF registry were divided into two groups according to whether they were treated with ACEI/ARB at recruitment. Baseline characteristics were carefully collected and analyzed. Logistic regression was utilized to identify the predictors of ACEI/ARB therapy. The primary endpoint was all-cause mortality, while the secondary endpoints included cardiovascular mortality, stroke and major adverse events (MAEs) during the one-year follow-up period. Univariable and multivariable Cox regression were performed to identify the association between ACEI/ARB therapy and the one-year outcomes. RESULTS: In total, 759 AF patients (38.1%) were treated with ACEI/ARB. Compared with AF patients without ACEI/ARB therapy, patients treated with ACEI/ARB tended to be older and had a higher rate of permanent AF, hypertension, diabetes mellitus, heart failure (HF), left ventricular ejection fraction (LVEF) < 40%, coronary artery disease (CAD), prior myocardial infarction (MI), left ventricular hypertrophy, tobacco use and concomitant medications (all P < 0.05). Hypertension, HF, LVEF < 40%, CAD, prior MI and tobacco use were determined to be predictors of ACEI/ARB treatment. Multivariable analysis showed that ACEI/ARB therapy was associated with a significantly lower risk of one-year all-cause mortality [hazard ratio (HR) (95% CI): 0.682 (0.527-0.882), P = 0.003], cardiovascular mortality [HR (95% CI): 0.713 (0.514-0.988), P = 0.042] and MAEs [HR (95% CI): 0.698 (0.568-0.859), P = 0.001]. The association between ACEI/ARB therapy and reduced mortality was consistent in the subgroup analysis. CONCLUSIONS: In patients with AF, ACEI/ARB was related to significantly reduced one-year all-cause mortality, cardiovascular mortality and MAEs despite the high burden of cardiovascular comorbidities.
