The impact of fetuin-A on predicting aortic arch calcification: secondary analysis of a community-based survey.

Introduction: Atherosclerotic cardiovascular disease is associated with a high mortality rate due to vascular calcification. The role of fetuin-A in aortic arch calcification (AAC) is less well understood. Methods: An analysis of secondary biomarkers was performed on 800 individuals from the biobank using the community database. AAC was defined by radiologists based on imaging. Multiple variables logical analysis was used for risk analysis. Results: A total of 736 individual samples were collected based on age and gender. The average age is 65 ± 10 years, and half the population comprises men. In spite of similar body weight, renal function, and hepatic function, the AAC group had higher blood pressure and fetuin-A levels independently: systolic blood pressure (SBP) index ≥130 mmHg [adjusted odds ratio (aOR) 1.85, 95% confidence interval (CI) 1.34-2.57, p = 0.002] and fetuin-A (aOR 0.62, 95% CI 0.50-0.76, p < 0.001). Moreover, it is evident that AAC can be predicted more accurately when combined with SBP ≥130 mmHg and a low fetuin-A level (<358 µg/ml: aOR 5.39, 95% CI 3.21-9.08) compared with the reference. Conclusion: Low fetuin-A levels are significantly correlated with AAC while there is an increased association between vascular calcification and coexisting hypertension.

Ticagrelor versus Adjusted-Dose Prasugrel in Acute Coronary Syndrome with Percutaneous Coronary Intervention.

Dual antiplatelet therapy (DAPT) with ticagrelor or adjusted-dose prasugrel has been used for acute coronary syndrome (ACS). However, few studies have directly compared these two drugs. In this study, we compared the real-world applications and outcomes of these two drugs in patients with ACS who had undergone percutaneous coronary intervention (PCI). This retrospective cohort study was conducted using the data of eligible patients with ACS who had undergone PCI at Chang Gung Memorial Hospital System between June 2019 and December 2021. The primary efficacy-related outcome was the occurrence of major adverse cardiovascular events (MACEs), and the primary safety-related outcome was major bleeding. Inverse probability of treatment weighting based on propensity score was performed to reduce confounding effects. The study included 2,636 patients; of them, 429 received prasugrel and 2,207 received ticagrelor. No significant between-group difference was observed in the risk of MACE (13.1 vs. 13.1 events per 100 person-years, respectively, hazard ratio (HR): 1.01, 95% confidence interval (CI): 0.71-1.43). Both groups exhibited similar rates of major bleeding (3.9 vs. 4.1 events per 100 person-years, respectively, subdistribution HR: 0.96, 95% CI: 0.68-1.35). In real-world settings, adjusted-dose prasugrel and ticagrelor exhibit comparable safety and efficacy profiles in East Asian patients with ACS after PCI. Our findings offer valuable insights for future clinical decision making and patient management strategies.

Comparing angiotensin receptor-neprilysin inhibitors with sodium-glucose cotransporter 2 inhibitors for heart failure with diabetes mellitus.

BACKGROUND AND AIMS: Clinical comparisons of angiotensin receptor-neprilysin inhibitors (ARNI) and sodium-glucose cotransporter 2 inhibitors (SGLT2i) treatment in patients with HFrEF and T2DM are limited. This study evaluated the clinical outcomes and treatment benefits of SGLT2i versus ARNI treatment in patients with HFrEF and T2DM in a large real-world data set. METHODS: We identified 1487 patients with HFrEF and T2DM who were undergoing ARNI or SGLT2i treatment for the first time (n = 647 and 840, respectively) between January 1, 2016, and December 31, 2021, and with clinical outcomes of CV death, hospitalization for heart failure (HHF), composite CV outcomes, or renal outcomes. RESULTS: The HHF risk reduction conferred by SGLT2i treatment was more significant than that conferred by ARNI treatment (37.7% vs. 30.4%; 95% confidence interval [CI] 1.06-1.41). SGLT2i use conferred significantly greater renal protection against the doubling of serum creatinine (13.1% vs. 9.3%; 95% CI 1.05-1.75), an estimated glomerular filtration rate decline of > 50% (24.9% vs. 20.0%; 95% CI 1.02-1.45), and progression to end-stage renal disease (3.1% vs. 1.5%; 95% CI 1.62-5.23). The improvements in echocardiographic parameters were comparable between the groups. CONCLUSIONS: Compared with ARNI treatment, SGLT2i treatment was associated with a more significant HHF risk reduction and greater preservation of renal function in patients with HFrEF and T2DM. This study also supports the prioritization of SGLT2i use in these patients when patients' conditions or economic resources need to be considered.

Acute heart failure with mildly reduced ejection fraction and myocardial infarction: a multi-institutional cohort study.

BACKGROUND: Little research has been done on ischemic outcomes related to left ventricular ejection fraction (EF) in acute decompensated heart failure (ADHF). METHODS: A retrospective cohort study was conducted between 2001 and 2021 using the Chang Gung Research Database. ADHF Patients discharged from hospitals between January 1, 2005, and December 31, 2019. Cardiovascular (CV) mortality and heart failure (HF) rehospitalization are the primary outcome components, along with all-cause mortality, acute myocardial infarction (AMI) and stroke. RESULTS: A total of 12,852 ADHF patients were identified, of whom 2,222 (17.3%) had HFmrEF, the mean (SD) age was 68.5 (14.6) years, and 1,327 (59.7%) were males. In comparison with HFrEF and HFpEF patients, HFmrEF patients had a significant phenotype comorbid with diabetes, dyslipidemia, and ischemic heart disease. Patients with HFmrEF were more likely to experience renal failure, dialysis, and replacement. Both HFmrEF and HFrEF had similar rates of cardioversion and coronary interventions. There was an intermediate clinical outcome between HFpEF and HFrEF, but HFmrEF had the highest rate of AMI (HFpEF, 9.3%; HFmrEF, 13.6%; HFrEF, 9.9%). The AMI rates in HFmrEF were higher than those in HFpEF (AHR, 1.15; 95% Confidence Interval, 0.99 to 1.32) but not in HFrEF (AHR, 0.99; 95% Confidence Interval, 0.87 to 1.13). CONCLUSION: Acute decompression in patients with HFmrEF increases the risk of myocardial infarction. The relationship between HFmrEF and ischemic cardiomyopathy, as well as optimal anti-ischemic treatment, requires further research on a large scale.

The cardiovascular and renal effects of glucagon-like peptide 1 receptor agonists in patients with advanced diabetic kidney disease.

BACKGROUND: To determine whether glucagon-like peptide 1 receptor agonists (GLP-1RAs) have cardiovascular and renal protective effects in patients with advanced diabetic kidney disease (DKD) with an estimated glomerular filtration rate (eGFR) < 30 mL/min per 1.73 m2. METHODS: In this cohort study, patients with type 2 diabetes mellitus and eGFR < 30 mL/min per 1.73 m2 with a first prescription for GLP-1RAs or dipeptidyl peptidase 4 inhibitors (DPP-4is) from 2012 to 2021 (n = 125,392) were enrolled. A Cox proportional hazard model was used to assess the cardiorenal protective effects between the GLP-1RA and DDP-4i groups. RESULTS: A total of 8922 participants [mean (SD) age 68.4 (11.5) years; 4516 (50.6%) males; GLP-1RAs, n = 759; DPP-4is, n = 8163] were eligible for this study. During a mean follow-up of 2.1 years, 78 (13%) and 204 (13.8%) patients developed composite cardiovascular events in the GLP-1RA and DPP-4i groups, respectively [hazard ratio (HR) 0.88, 95% confidence interval CI 0.68-1.13]. Composite kidney events were reported in 134 (38.2%) and 393 (44.2%) patients in the GLP-1RA and DPP-4i groups, respectively (subdistribution HR 0.72, 95% CI 0.56-0.93). CONCLUSIONS: GLP-1RAs had a neutral effect on the composite cardiovascular outcomes but reduced composite kidney events in the patients with advanced DKD compared with DPP-4is.

Optimal Heart Rate Control Improves Long-Term Prognosis of Decompensated Heart Failure with Reduced Ejection Fraction.

Background and Objectives: An elevated heart rate is an independent risk factor for cardiovascular disease; however, the relationship between heart rate control and the long-term outcomes of patients with heart failure with reduced ejection fraction (HFrEF) remains unclear. This study explored the long-term prognostic importance of heart rate control in patients hospitalized with HFrEF. Materials and Methods: We retrieved the records of patients admitted for decompensated heart failure with a left ventricular ejection fraction (LVEF) of ≤40%, from 1 January 2005 to 31 December 2019. The primary outcome was a composite of cardiovascular death or hospitalization for heart failure (HHF) during follow-up. We analyzed the outcomes using Cox proportional hazard ratios calculated using the patients' heart rates, as measured at baseline and approximately 3 months later. The mean follow-up duration was 49.0 ± 38.1 months. Results: We identified 5236 eligible patients, and divided them into five groups on the basis of changes in their heart rates. The mean LVEFs of the groups ranged from 29.1% to 30.6%. After adjustment for all covariates, the results demonstrated that lesser heart rate reductions at the 3-month screening period were associated with long-term cardiovascular death, HHF, and all-cause mortality (p for linear trend = 0.033, 0.042, and 0.003, respectively). The restricted cubic spline model revealed a linear relationship between reduction in heart rate and risk of outcomes (p for nonlinearity > 0.2). Conclusions: Greater reductions in heart rate were associated with a lower risk of long-term cardiovascular death, HHF, and all-cause mortality among patients discharged after hospitalization for decompensated HFrEF.

Effect of the Ligation and Reperfusion Timeframe on Maximal Ischemia-Reperfusion Injury in Diverse Rat Models.

Background: Little is known about the effect that different time sequences for coronary ligation and reperfusion have on ischemic-reperfusion (IR) injury. Objective: To investigate the relationship between the extent of IR injury and the timeframe for coronary ligation/reperfusion in three animal models. Methods: Three rat models were used: normal Sprague-Dawley rats, diabetes mellitus (DM) rats, and fat rats. The rats in each model were divided into four groups based on the coronary ligation period (L): 30, 60, 120, and 180 min, and then divided into seven sub-groups based on the reperfusion period (R): 0, 30, 60, 120, 180, 270, and 360 min. R0 was the IR injury baseline for each sub-group. The hearts were harvested and stained with Evans blue and 2,3,5-triphenyl tetrazolium chloride dye to distinguish the different myocardial injury areas: area at risk (AAR) and myocardial necrosis. The difference between each subgroup and baseline (R0) for the necrotic area/AAR was calculated. Results: In the normal rats, the highest IR injury differences compared with the baseline group occurred at L120, with a reperfusion time of > 180 min. The highest IR injury difference compared to the baseline group occurred at L30, with a reperfusion time of > 180 min in the DM rats and at L60R270, L120R180 in the fat rats. Conclusions: IR injury, as induced by different coronary ligation and reperfusion time intervals, had diverse expression profiles in the different animal models. Optimal animal models with optimal coronary ligation/reperfusion protocols to achieve maximal IR injury will affect the results and interpretation of future studies.

Direct-Acting Antivirals Reduce the De Novo Development of Esophageal Varices in Patients with Hepatitis C Virus Related Liver Cirrhosis.

The real-world benefits of direct-acting antiviral (DAA)-induced sustained virologic response (SVR) on the de novo occurrence and progression of esophageal varices (EV) remain unclear in patients with hepatitis C virus (HCV)-related liver cirrhosis (LC). This is a retrospective cohort study evaluating all patients with Child-Pugh class A HCV-related LC during 2013 to 2020 in the Chang Gung Medical System. A total of 215 patients fit the inclusion criteria and were enrolled. Of them, 132 (61.4%) patients achieved DAA induced-SVR and 83 (38.6%) did not receive anti-viral treatment. During a median follow-up of 18.4 (interquartile range, 10.1−30.9) months, the 2-year incidence of de novo EV occurrence was 8 (7.0%) in the SVR group and 7 (12.7%) in the treatment-naïve group. Compared to the treatment-naïve group, the SVR group was associated with a significantly lower incidence of EV occurrence (adjusted hazard ratio [aHR]: 0.47, p = 0.030) and a significantly lower incidence of EV progression (aHR: 0.55, p = 0.033). The risk of EV progression was strongly correlated with the presence of baseline EV (p < 0.001). To the best of our knowledge, this is the first study to demonstrate that DAA-induced SVR is associated with decreased risk of de novo EV occurrence and progression in the real world.

From self-care behaviours to cardiometabolic risks prevention for the health of farmers: Nursing implications.

AIMS: The study aimed to explore farmers' self-care behaviours including oral hygiene, remaining natural teeth, cardiometabolic risks, hepatitis, risk of stroke and their determinant factors. METHODS: This cross-sectional study was conducted between June 2020 and March 2021 in the south-western remote areas of Taiwan. We recruited current farmers who participated in an annual community health screening conducted by a collaborated local hospital. Data were collected through face-to-face interviews using a semi-structured questionnaire. Blood samples were drawn and stored in the central laboratory of the cooperating hospital. The study outcomes included cardiometabolic risks, the remaining natural teeth, and farmers' self-care behaviours including oral hygiene, adopting a healthy diet and substance use. RESULTS: Overall, 183 current farmers (55.2% women, aged 66.9 ± 11.7 years) were enrolled. Abnormal blood pressure, high risk of stroke, metabolic syndrome and hepatitis C virus infection were found among the participants. The average remaining teeth were 12.1, 73.2% of participants had <20 teeth; 90.2% and 71% did not undergo regular dental check-ups and scaling or use dental floss, respectively. The determinant factors associated with the remaining teeth included a high risk of stroke, teeth scaling and dental floss use. Although only 3.8% felt mentally distressed, many farmers were unaware of having potential cardiometabolic diseases and curable viral hepatitis, and only two had received antiviral treatment. CONCLUSION: The farmers in this study had a high prevalence of cardiometabolic risks, a high probability of stroke, inadequate number of remaining teeth and poor oral hygiene behaviours. These findings can provide evidence to develop health promotion programmes for farmers. IMPACT: This study demonstrates the health needs of farmers. We strongly recommend that community nurses empower farmers to engage in self-care behaviours through tailored health promotion programmes. For instance, by discussing cardiometabolic risk prevention from the farmers' perspectives to improve their health literacy.

Association between viral hepatitis and metabolic syndrome in lung function impairment: A Taiwan community-based study.

OBJECTIVES: Metabolic syndrome (MetS) and hepatitis C virus (HCV) are associated with a higher risk of impaired pulmonary function (iPF). This study aimed to investigate the relationships among MetS, iPF, and viral hepatitis. METHODS: This community-based study enrolled participants undergoing annual health check-ups in southern Taiwan between March and December 2019. We performed multivariable logistic regression analyses adjusted for demographics and characteristics to identify the factors associated with iPF. RESULTS: A total of 2337 participants completed examinations, of whom 928 (39.7%) had iPF. The participants with iPF were elderly (68.8 ± 12.8 years old) and predominately female (63%). MetS increased the risk of iPF (odds ratio (OR) 1.51, 95% confidence interval (CI) 1.27-1.81, p < 0.001). Beyond age (OR 1.03, 95% CI 1.02-1.04) and smoking (OR 1.309, 95% CI 1.004-1.705), female sex (OR 0.74, 95% CI 0.59-0.93) and high education level (OR 0.96, 95% CI 0.94-0.98, p < 0.001) protected against iPF. HCV was not significantly associated with iPF (OR 1.17, 95% CI 0.90-1.52, p = 0.235) in multivariable analysis. MetS was associated with a higher risk of iPF in the non-HBV/HCV group (OR 1.86, 95% CI 1.54-2.26) and HBV alone group (OR 3.44, 95% CI 1.89-6.28), but not in the HCV alone group (OR 1.02, 95% CI 0.64-1.62). DISCUSSION: MetS was an independent predictor of iPF, especially the restrictive type, and had different effects in the HBV/non-viral hepatitis and HCV groups. Female sex and education were inversely associated with iPF.

A novel nomogram for predicting cardiometabolic diseases from modifiable risks in middle-aged adults-implication for health education.

Background: Middle-aged adults often overlook critical modifiable risk factors that contribute to the emergence of cardiometabolic diseases (CMDs), including hypertension and diabetes. Many CMDs can be alleviated by addressing these modifiable risks. However, there has been insufficient research focused on rural adults with lower levels of health literacy in this regard. The aim of this study was to explore and develop an intuitive assessment tool for predicting cardiometabolic diseases (CMDs), which can be used for health education with adults of low health literacy. Methods: This was a community-based, cross-sectional study. A structured questionnaire on health-promoting habits, smoking, sleep, and physiological biomarkers was obtained via community health screening in the coastal region of Yunlin County, Taiwan. Multivariate logistic regression was used to screen for significant variables in the nomogram construction. Analysis with nonlinear restricted cubic spline was performed. Results: A total of 712 participants (60.9% females) aged 40-64 years, with middle school level or lower education, were included. The average age was 55.6 years (SD=7.3), and 220 individuals (31%) had CMDs. Multivariate logistic regression analysis revealed that age, lower scores of vegetables, fruit, water, and exercise (VFWE), smoking history, sleep deprivation, and being overweight were significantly associated with CMDs. The model incorporating these modifiable risk factors demonstrated good discriminatory ability, as indicated by an area under the receiver operating characteristic curve of 0.75 (0.73-0.76). A predictive nomogram was developed that presented modifiable risk factors in a simple graphical format to facilitate the prediction of CMDs. Conclusions: This study highlights a high prevalence of CMDs among middle-aged adults, along with the disregard for important risk factors that could be modified. The developed nomogram could be a practical and effective tool for community health education to enhance health literacy and prevent the progression of CMDs.

Early administration of ivabradine in patients admitted for acute decompensated heart failure.

Background: Heart rate (HR) control is important in heart failure (HF) patients with reduced ejection fraction, and ivabradine is indicated for patients with chronic HF and sinus rhythm. However, ivabradine is limited in initiation of ivabradine at acute stage of HF. Materials and methods: This multi-institutional retrospective study enrolled 30,639 patients who were admitted for HF from January 01, 2013 to December 31, 2018 at Chang Gung Memorial Hospitals. After applying selection criteria, the eligible patients were divided into ivabradine and non-ivabradine groups according to the initiation of ivabradine at the index hospitalization. HR, clinical outcomes including HF hospitalization, all-cause hospitalization, mortality, the composite of cardiovascular (CV) death or HF hospitalization and newly developed atrial fibrillation, and left ventricular ejection fraction (LVEF) and left atrium size were compared between the ivabradine and non-ivabradine groups after inverse probability of treatment weighting (IPTW) analysis after 12 months. Results: The HR at admission in the ivabradine group (n = 433) was 99.04 ± 20.69/min, compared to 86.99 ± 20.34/min in the non-ivabradine group (n = 9,601). After IPTW, HR was lower in the ivabradine group than that in the non-ivabradine group after 12 months (74.14 ± 8.53 vs. 81.23 ± 16.79 bpm, p = 0.079). However, there were no significant differences in HF hospitalization (HR = 1.02; 95% CI, 0.38-2.79), all-cause hospitalization (HR = 0.95; 95% CI, 0.54-1.68), mortality (HR = 0.87; 95% CI, 0.69-1.08), the composite of CV death or HF hospitalization (HR = 0.87; 95% CI, 0.69-1.08) and newly developed AF between the two groups. In addition, LVEF increased with time in both groups, but there were no significant differences during the observation period. Conclusion: Ivabradine was beneficial in controlling HR when initiated in patients with acute stage of HF, but it did not seem to provide any benefits in reducing HF hospitalization, all-cause hospitalization, and mortality in 1 year after discharge.

Alanine aminotransferase to aspartate aminotransferase ratio and hepatitis B virus on metabolic syndrome: a community-based study.

Background: The serum aminotransferase elevation in metabolic syndrome (MetS) reflected hepatosteatosis, but there is a conflict with the coexistence of viral hepatitis, especially for the hepatitis B virus (HBV). Thus, this study aimed to investigate the relationship between the alanine aminotransferase (ALT)/aspartate aminotransferase (AST) ratio, MetS, and HBV infection in a rural Taiwanese population. Methods: We conducted a cross-sectional analysis in southern Taiwan between March and December 2019. Multivariable logistic regression analyses adjusted for demographics, education, dietary behaviors, irregular exercise, substance use, and viral markers were performed to investigate the association between the ALT/AST ratio and MetS. Results: Altogether, 2,416 participants (891 men and 1,525 women; mean age, 64.1 ± 14.9 years) were enrolled. Of the participants, 22.7% (n = 519) were seropositive for viral hepatitis. In the multivariable analysis, age [odds ratio (OR) 1.02, 95% CI 1.01-1.03, p < 0.001], ALT/AST ratio >1 (OR 2.63, 95% CI 2.15-3.21, p < 0.001), education (OR 0.96, 95% CI 0.94-0.98, p < 0.001), and HBV seropositivity (OR 0.70, 95% CI 0.52-0.95, p = 0.021) were associated with the risk of MetS. The area under the curve of the ALT/AST ratio was 0.62 (95% CI 0.60-0.64, p < 0.001), and the cutoff value was >0.852 for the Youden index. Conclusion: An ALT/AST ratio >1 could be a simple index for MetS prediction during community checkups. In contrast to age and betel nut chewing, HBV seropositivity and higher education might be inversely associated with MetS. Aggressive health promotion for MetS prevention has emerged as essential in participants without HBV and with lower education levels. Further large-scale, longitudinal studies are needed to unlink these correlations.

Health Inequality among Fishery Workers during Climate Change: A National Population-Based and Retrospective Longitudinal Cohort Study.

Background: Owing to specific working environments, it is important to attain sustainable development goals for the health of fishery workers during climate change. Fishery workers have a hazardous working environment, leading to specific injuries and fatal events. However, limited studies have investigated the health status of fishery workers through long-term longitudinal follow-up and compared it with that of farmers and employed workers with similar socioeconomic status. Methods: The Longitudinal Health Insurance Database 2000, a subset of the Taiwan National Health Insurance Research Database was used for this retrospective cohort study. Only fishery workers, farmers, and employed workers were included. Based on the majority of causes of death and related diseases, participants newly diagnosed with 18 diseases, classified into cardiometabolic diseases, mental illness, chronic kidney disease, infection, and malignancy, were included. Participants with an old diagnosis of these diseases were excluded. All included participants were followed up from 1 July 2000 to the diagnosis and withdrawal date, or 31 December 2012, whichever occurred first. Due to the substantial difference in the baseline demographics, we executed a cohort study with propensity score-matched and applied the Cox model to explore the participants' health status. Results: After matching, there were negligible differences in the baseline demographics of fishery workers, farmers, and employed workers. Compared to farmers and employed workers, fishery workers were more frequently diagnosed with 11 and 14 diseases, respectively, such as hypertension (hazard ratio [HR]: 1.11, p < 0.01), diabetes (HR: 1.21, p < 0.001), dyslipidemia (HR: 1.18, p < 0.001), depression (HR: 1.38, p < 0.001), peptic ulcer (HR: 1.17, p < 0.001), chronic viral hepatitis (HR: 2.06, p < 0.001), hepatocellular carcinoma (HR: 1.67, p < 0.001), and total malignancy (HR: 1.26, p < 0.001). Conclusions: Compared to farmers and employed workers, fishery workers were more impacted by cardiometabolic diseases, mental illness, infection, and malignancy. Therefore, it is imperative to specifically focus on health policies for fishery workers, such as providing curable antiviral treatment and initiating culture-tailored health promotion programs, to mitigate health inequality.

Ivabradine in heart failure patients with reduced ejection fraction and history of paroxysmal atrial fibrillation.

AIMS: Ivabradine is indicated for heart failure (HF) patients with reduced ejection fraction (HFrEF), but limited data are available with regards to the use of ivabradine in those with a history of paroxysmal atrial fibrillation (AF). To assess the effect of ivabradine in HFrEF patients with paroxysmal AF, we analysed heart failure (HF) hospitalization and mortality from multiple-centre registry database. METHODS AND RESULTS: We conducted a multicentre observational matched cohort study, and this study enrolled patient with symptomatic HFrEF from 1 January 2015 to 31 December 2018 who had a history of paroxysmal AF in Chang Gung Memorial Hospital medical database in Taiwan. A total of 2042 patients were eligible for the study, of whom 887 were prescribed with ivabradine and 1115 were not. The primary outcome, including HF hospitalization and cardiovascular death, and individual outcome during the 12 month observation period were analysed after inverse probability of treatment weighting. The ivabradine group had significantly lower mean heart rate after 12 months follow-up than the non-ivabradine group (P < 0.05). The primary outcome was significantly higher in the ivabradine group than the non-ivabradine group after 12 months follow-up (hazard ratio [HR] = 1.58; 95% confidence interval [CI], 1.26-2.00, P < 0.001). Moreover, the ivabradine group had a significantly higher event rate of HF hospitalization (HR = 1.56; 95% CI, 1.40-1.75, P < 0.001) and HF death (HR = 1.67; 95% CI, 1.14-2.44, P = 0.009) than the non-ivabradine group. CONCLUSIONS: Ivabradine treatment was associated with an increased risk of HF hospitalization in symptomatic HFrEF patients with a history of paroxysmal AF. Further prospective randomized studies are warranted.

The Impact of Hepatitis C Virus, Metabolic Disturbance, and Unhealthy Behavior on Chronic Kidney Disease: A Secondary Cross-Sectional Analysis.

BACKGROUND: Hepatitis C virus (HCV) infection is associated with a higher risk of chronic kidney disease (CKD). This study investigates the relationship among HCV, CKD, and understudied confounders, such as unhealthy behaviors and metabolic disturbances. METHODS: This cross-sectional study was conducted as part of a community health promotion program in an HCV endemic area of Taiwan from June to December 2019. Multivariable logistic regression analyses adjusted for demographic and clinical characteristics were performed to investigate the association between CKD and HCV seropositivity. RESULTS: Of 2387 participants who underwent health check-ups, the mean age was 64.1 years old; females predominated (63.2%), and 306 (12.8%) subjects were seropositive for HCV. CKD, defined as a lower estimated glomerular filtration rate (eGFR) was associated with unhealthy dietary habits, metabolic syndrome, and HCV. Less frequent exercise, higher waist circumference (WC) and HbA1c all affected risk of CKD; HCV increased risk of CKD by 44% compared to non-HCV (OR 1.44, 95% confidence interval (CI) 1.05-1.98) in the multivariable analysis. In the HCV group, lower eGFR was also significantly associated with the severity of metabolic syndrome (MetS) (median eGFR was 86.4, 77.1, and 64.5 mL/min/1.73 m2 for individuals with three and five MetS components, respectively). CONCLUSIONS: Beyond metabolic disturbance and irregular exercise, HCV seropositivity is independently associated with CKD in a community survey. Healthy lifestyle promotion might protect against renal function decline in HCV; however, the mechanisms underlying the association need further large-scale investigation.

Cardioselective Versus Nonselective ß-Blockers After Myocardial Infarction in Adults With Chronic Obstructive Pulmonary Disease.

OBJECTIVE: To investigate which types of ß-blockers have better efficacy and safety profiles in patients with concomitant chronic obstructive pulmonary disease (COPD) and myocardial infarction (MI) to address concerns about use of ß-blockers in COPD. METHODS: We identified 65,699 patients with COPD prescribed ß-blockers after first MI in the Taiwan National Health Insurance Research Database between January 1, 2001, and December 31, 2013. Comparisons were performed using the inverse probability of treatment weighting method. The primary outcome was all-cause mortality; secondary outcomes were heart failure hospitalization, major adverse cardiac and cerebrovascular event (MACCE), and major adverse pulmonary event (MAPE). RESULTS: A total of 14,789 patients prescribed ß-blockers were enrolled, of whom 7247 (49.0%) used cardioselective ß-blockers and 7542 (51.0%) used nonselective ß-blockers. The cardioselective group had lower incidence rates of mortality (hazard ratio [HR], 0.93; 95% CI, 0.89 to 0.96), MACCE (HR, 0.96; 95% CI, 0.93 to 0.998), heart failure hospitalization (subdistribution HR, 0.84; 95% CI, 0.78 to 0.91), and MAPE (HR, 0.94; 95% CI, 0.90 to 0.98) at the end of follow-up after weighting. Similar results were also found in subgroup analysis between those prescribed bisoprolol and those prescribed carvedilol. CONCLUSION: Patients prescribed a cardioselective ß-blocker may have a lower incidence of all-cause mortality, MACCE, heart failure hospitalization, and MAPE than those prescribed a nonselective ß-blocker. Cardioselective ß-blocker treatment during hospitalization and continuing after discharge appears to be superior to nonselective ß-blocker treatment in patients with COPD after MI.

Venous Thromboembolism and Critical Limb Events in Patients with Atrial Fibrillation: A Nationwide Population-Based Cohort Study.

Little is known about whether venous thromboembolism (VTE) causes worse critical limb events in populations with atrial fibrillation (AF). A retrospective cohort study using claims data from Taiwan's National Health Insurance program between 2001 and 2013 compared AF patients with or without VTE. Outcomes were percutaneous transluminal angioplasty (PTA), amputation, systemic thromboembolism, all-cause mortality, cardiovascular death, ischemic stroke, and acute myocardial infarction. Patients (n = 316,817) with newly diagnosed AF were analyzed; of those, 2514 (0.79%) had VTE history. After inverse probability of treatment weighting, a history of VTE was significantly associated with higher risks of PTA (3.3 vs 2.2%; subdistribution hazard ratio [SHR] 1.47; 95% confidence interval [CI] 1.17-1.84); above knee amputation (0.7 vs 0.3%; HR 2.15; 95% CI 1.10-4.21); systemic thromboembolism (5.8 vs 3.9%; SHR 1.48; 95% CI 1.21-1.80); all-cause mortality (53 vs 46.4%; HR 1.20, 95% CI 1.12-1.29); and cardiovascular death (34.8 vs 29.4%; HR 1.25, 95% CI 1.14-1.36). In conclusion, VTE might increase the risk of critical lower limb events (PTA and above-knee amputation), systemic thromboembolism, and mortality in the AF population. However, current data cannot confirm a causal relationship between VTE and clinical outcomes in this population.

Differential Presentations of Arterial Thromboembolic Events Between Venous Thromboembolism and Atrial Fibrillation Patients.

Objective: Atrial fibrillation (AF) and venous thromboembolism (VTE) share several risk factors related to arterial thromboembolism. No study has reported the differential contribution to arterial thromboembolic events and mortality between these two conditions in the same population. We therefore assessed the differential arterial thromboembolic events between AF and VTE. Methods: We included AF and VTE national cohorts derived from Taiwan National Health Insurance Research Database between 2001 and 2013. The eligible population was 314,861 patients in the AF cohort and 41,102 patients in the VTE cohort. The primary outcome was arterial thromboembolic events, including ischemic stroke, extracranial arterial thromboembolism (ECATE) and myocardial infarction (MI). Secondary outcomes were all-cause mortality and cardiovascular death. Results: After a 1:1 propensity matching, 32,688 patients in either group were analyzed. The risk of arterial thromboembolic events was lower in the VTE cohort than that in the AF cohort (subdistribution hazard ratio [SHR], 0.60; 95% confidence interval [CI], 0.57-0.62). The risk of ischemic stroke (SHR, 0.44; 95% CI, 0.42-0.46) and MI (SHR, 0.80; 95% CI, 0.72-0.89) were lower in the VTE cohort, while the risk of ECATE (SHR, 1.23; 95% CI, 1.14-1.33; particularly lower extremities) was higher in the VTE cohort. All-cause mortality rate was higher in the VTE cohort (HR, 1.18; 95% CI, 1.15-1.21) while the risk of cardiovascular death was lower in the VTE cohort (HR, 0.96; 95% CI, 0.93-0.995). Conclusions: Patients with AF had higher risks of arterial thromboembolic events compared to patients with VTE, despite having risk factors in common. The VTE cohort had higher risks of all-cause mortality and ECATE, particularly lower extremity events, compared to AF patients. The differential manifestations of thromboembolism sequelae and mortality between AF and VTE patients merit further investigation.

Hepatitis C-associated late-onset schizophrenia: a nationwide, population-based cohort study.

BACKGROUND: Whether infection with the hepatitis C virus (HCV) causes schizophrenia - and whether the associated risk reverses after anti-HCV therapy - is unknown; we aimed to investigate these topics. METHODS: We conducted a nationwide, population-based cohort study using the Taiwan National Health Insurance Research Database (TNHIRD). A diagnosis of schizophrenia was based on criteria from the International Classification of Diseases, 9th revision (295.xx). RESULTS: From 2003 to 2012, from a total population of 19 298 735, we enrolled 3 propensity-score-matched cohorts (1:2:2): HCV-treated (8931 HCV-infected patients who had received interferon-based therapy for ≥ 6 months); HCV-untreated (17 862); and HCV-uninfected (17 862) from the TNHIRD. Of the total sample (44 655), 82.81% (36 980) were 40 years of age or older. Of the 3 cohorts, the HCV-untreated group had the highest 9-year cumulative incidence of schizophrenia (0.870%, 95% confidence interval [CI] 0.556%-1.311%; p < 0.001); the HCV-treated (0.251%, 95% CI 0.091%-0.599%) and HCV-uninfected (0.118%, 95% CI 0.062%-0.213%) cohorts showed similar cumulative incidence of schizophrenia (p = 0.33). Multivariate Cox analyses showed that HCV positivity (hazard ratio [HR] 3.469, 95% CI 2.168-5.551) was independently associated with the development of schizophrenia. The HCV-untreated cohort also had the highest cumulative incidence of overall mortality (20.799%, 95% CI 18.739%-22.936%; p < 0.001); the HCV-treated (12.518%, 95% CI 8.707%-17.052%) and HCV uninfected (6.707%, 95% CI 5.533%-8.026%) cohorts showed similar cumulative incidence of mortality (p = 0.12). LIMITATIONS: We were unable to determine the precise mechanism of the increased risk of schizophrenia in patients with HCV infection. CONCLUSION: In a population-based cohort (most aged ≥ 40 years), HCV positivity was a potential risk factor for the development of schizophrenia; the HCV-associated risk of schizophrenia might be reversed by interferon-based antiviral therapy.
