RESUMO
OBJECTIVES: Exosomes are membrane vesicles that are actively secreted in response to microenvironmental stimuli. In this study, we quantified the amount of exosomes in patients with significant coronary artery disease (CAD) and evaluated its relationship with myocardial perfusion imaging (MPI) results. METHODS: Patients who underwent both MPI and coronary angiography were recruited. Plasma was collected during angiography, and exosomes were extracted via the precipitation method. The summed stress scores (SSS), summed difference scores, and ventricular functional parameters were calculated from the MPI and compared with the amounts of exosomes and extracted miRNAs. RESULTS: In total, 115 patients were enrolled (males: 78 %; mean age: 66.6 ± 10.6 years). Those with abnormal SSS according to the MPI had significantly fewer exosomes (p = 0.032). After multivariate analysis, the SSS remained significantly related to the amount of exosomes (p = 0.035). In forty randomly selected samples, miRNA-432-5p and miRNA-382-3p were upregulated in patients with abnormal SSS. CONCLUSIONS: Patients with compromised poststress myocardial perfusion on MPI tended to have fewer exosomes in association with CAD-related miRNAs. This is the first study to clarify the fundamental and pathophysiological causes of CAD using radiographic examinations.
RESUMO
OBJECTIVE: In patients with atrial fibrillation (AF) and end-stage renal disease (ESRD), oral anticoagulants are contraindicated, and left atrial appendage occlusion (LAAO) is an alternative treatment. However, the efficacy of thromboembolic prevention using LAAO in these patients has rarely been reported in Asian populations. To our knowledge, this is the first long-term LAAO study in patients with AF undergoing dialysis in Asia. METHODS: In this study, 310 patients (179 men) with a mean age of 71.3 ± 9.6 years and mean CHA2DS2-VASc 4.2 ± 1.8 were consecutively enrolled at multiple centers in Taiwan. The outcomes of 29 patients with AF and ESRD undergoing dialysis who underwent LAAO were compared to those without ESRD. The primary composite outcomes were stroke, systemic embolization, or death. RESULTS: No difference in mean CHADS-VASc score was noted between patients with versus without ESRD (4.1 ± 1.8 vs. 4.6 ± 1.9, p = 0.453). After a mean follow-up of 38 ± 16 months, the composite endpoint was significantly higher in patients with ESRD (hazard ratio, 5.12 [1.4-18.6]; p = 0.013) than in those without ESRD after LAAO therapy. Mortality was also higher in patients with ESRD (hazard ratio, 6.6 [1.1-39.7]; p = 0.038). The stroke rate was numerically higher in patients with versus without ESRD, but the difference was not statistically significant (hazard ratio, 3.2 [0.6-17.7]; p = 0.183). Additionally, ESRD was associated with device-related thrombosis (odds ratio, 6.15; p = 0.047). CONCLUSION: Long-term outcomes of LAAO therapy may be less favorable in patients with AF undergoing dialysis, possibly because of the poor condition of patients with ESRD.

BACKGROUND: Social detachment includes the subjective aspect "loneliness" and the objective aspect "social isolation," but tools to assess both dimensions are limited. This study aims to develop a questionnaire, the Social Detachment Questionnaire for Older Population (SDQO), that considers multiple dimensions of social detachment simultaneously. METHODS: The study collected 600 valid samples from individuals aged 55 and above to examine the psychometric properties of the developed SDQO. Item analysis was conducted to assess the performance of each item, and exploratory factor analysis (EFA) was employed to analyze its initial structure and eliminate less ideal items. Subsequently, confirmatory factor analysis (CFA) was used to examine the model fit of the suggested structure by EFA, using different subsamples. Internal consistency, concurrent validity, and other analyses were also performed. RESULTS: The original 27-item SDQO was reduced to 17 items after removing 4 questions in item analysis and 6 questions in EFA. The Cronbach's alpha for the 17-item version of SDQO was 0.80. Both EFA and CFA supported its 6-factor structure, with factors identified as community activities, loneliness, personal resources, leisure activities, friendship, and family resources. SDQO also demonstrated expected performance in concurrent validity. CONCLUSION: The 17-item version of SDQO exhibited good reliability and validity, measuring various aspects of social detachment behavior, feelings, and resources. It holds value for future research applications.
RESUMO
OBJECTIVES: This study investigated the impact of social activities on cognitive functioning and psychopathological symptoms. METHODS: Participants aged 55 or older were enrolled through communities. Initial measures assessed demographic data, neuropsychological functioning, psychopathological state, and happiness. Social activities were evaluated using a modified 12-item tool, with 3-4 activities as the cutoff. Follow-up after 6-9 months included Mini-Mental State Examination (MMSE), Beck Depression Inventory - II (BDI-II), Beck Anxiety Inventory (BAI), Health Assessment Questionnaire (HAQ), and Patient Health Questionnaire-15 (PHQ-15) measurements. Predictive models for psychiatric and cognitive statuses were built using multiple linear regression, adjusting for baseline conditions. RESULTS: Initially, 516 older individuals enrolled, with 403 undergoing follow-up. During follow-up, the low participation group reported lower MMSE scores, higher BAI scores, and increased PHQ-15 risk. Negative correlations between social activity numbers and PHQ-15 results were found. Engagement in social clubs correlated positively with higher MMSE scores, while regular interactions with one's adult child(ren) were linked to decreased BAI scores. CONCLUSIONS: The quantity of social activities was associated with lower somatic distress. Social club engagement positively influenced cognition, and regular interactions with one's adult child(ren) mitigated anxiety among older individuals. CLINICAL IMPLICATIONS: Enough types of social activities, participating in social clubs, and adequate interactions with children protected against psychopathologies.
RESUMO
Background: Heart failure (HF) is a significant public health problem worldwide. Death and rehospitalization rates are similar across different HF phenotypes. However, the existing Taiwanese HF registries mainly enrolled inpatients with HF and reduced ejection fraction (HFrEF) before 2019, so their results may not apply to outpatients or patients with HF with mildly reduced ejection fraction (HFmrEF) and HF with preserved ejection fraction (HFpEF) phenotypes. Methods: The Taiwan Society of Cardiology Heart Failure Registry 2020 is a prospective, multicenter, observational registry that will enroll patients with HF from 27 hospitals in Taiwan between 2020 and 2022 and will be followed for two years. Patients eligible for enrollment include those admitted due to acute decompensated heart failure or outpatients with a history of hospitalization for heart failure within the past six months. The registry will collect patient demographics, medical history, HF diagnosis, medication use, examination results, and comorbidities. The registry plans to enroll 3,370 patients, with the distribution of HFrEF/HFmrEF/HFpEF as 59%/13%/28%. Follow-up intervals will occur every six months for up to two years to monitor clinical outcomes and major cardiac interventions. The registry will conclude in December 2024. Conclusions: The Taiwan Society of Cardiology Heart Failure Registry 2020 is a comprehensive and meticulous effort to demonstrate the epidemiology, adherence to guidelines, clinical outcomes, and disease progression of Taiwanese patients with HF in contemporary clinical practice.
RESUMO
AIMS: Atrial fibrillation (AF) is one of the major causes of ischaemic stroke. In addition to clinical risk evaluated by the CHA2DS2-VASC score, the impact of genetic factors on the risk of AF-related thromboembolic stroke has been largely unknown. We found several copy number variations (CNVs) in novel genes that were associated with thromboembolic stroke risk in our AF patients by genome-wide approach. Among them, the gasdermin D (GSDMD) gene was related to inflammation. We aimed to test whether GSDMD deletion was associated with AF-related stroke. METHODS AND RESULTS: A total of 400 patients with documented non-familial AF were selected, of which 100 patients were diagnosed with ischaemic stroke. The baseline characteristics of age, sex, valvular heart disease, coronary artery disease, heart failure, and CHA2DS2-VASc scores were not statistically different between cases and controls. We found that individuals who carried GSDMD homozygous deletion genotype had a higher risk for ischaemic stroke (odds ratio 2.195; 95% confidence interval, 1.24-3.90; P = 0.007), even adjusted by CHA2DS2-VASc scores. We also validated the association of GSDMD with AF stroke in a large Caucasian population (UK Biobank). CONCLUSION: We found a link between the homozygous deletion of the GSDMD gene and an increased risk of stroke in patients with AF. This may implicate the use of therapy targeting GSDMD in the prevention of ischaemic stroke for AF patients.

BACKGROUND: We have demonstrated that bioresorbable vascular scaffold (BVS) for ACC/AHA type C lesions was associated with higher risks of long-term target lesion revascularization (TLR) and target lesion failure (TLF). We determined the specific time after which higher risks of BVS for type C lesions are reduced in a longer-term follow-up. METHODS: We analyzed data of 457 patients (59 ± 12 years, 87% male) with 714 BVS implanted for 529 lesions and a median follow-up of 56.4 (48.6-62.6) months. Patients with BVS for at least one type C lesion (N = 177) at index intervention and all non-type C lesions (N = 280) were compared for TLF (cardiac death, target vessel myocardial infarction, TLR). We specified the interactions between the non-type C versus type C group and the event-free survival times dichotomized at 24, 30, 32, 33, 36, and 39 months respectively. RESULTS: The type C group had more multivessel disease (86% versus 65%, p < 0.001), left anterior descending artery treated (68% versus 53%, p = 0.002), intravascular imaging used (48% vs. 25%, p < 0.001), and BVS (2.3 ± 0.9 vs. 1.1 ± 0.3, p < 0.001) implanted with a longer total length (57 ± 21 vs. 29 ± 8 mm, p < 0.001). The TLR or TLF was higher (both log-rank p < 0.05) in the type C than in the non-type C group. However, the risks of TLR (hazard ratio: 3.6, 95% CI = 1.1-11.6) and TLF (hazard ratio: 3.8, 95% CI = 1.2-12.1) for type C lesions only remained higher until 24 months post-BVS implantation. CONCLUSION: BVS provides a longer-term advantage, particularly for type C lesions with the majority requiring long stenting.

INTRODUCTION: Social participation activities have a close association with health aging. However, the clinical significance of numbers of social participation activities and its cutoff value has not been defined. METHODS: We recruited 516 people aged ≥55 years. Twelve social participation behaviors modified according to Taiwanese culture were investigated, and the adequacy of cutoff number was determined by the area under the receiver operating characteristic curve (AUC) according to the results of cluster analysis of individual activities and scores of the Brief Symptom Rating Scale-5 (BSRS-5) and the Chinese Happiness Inventory (CHI). Demographic, BSRS-5 and CHI data were then compared according to the candidate cutoff numbers. RESULTS: The distribution of the numbers of social activities suggested that the highest partition of numbers of social activities was 3 in women and 4 in men. The AUC regarding the cluster of activity types was 0.917, with the highest Youden's J value located between 3 and 4. The AUC regarding the cluster of activity types and scores of the BSRS-5 and the CHI was 0.929, with similar cutoffs. If 3 and 4 were used as cutoffs, the between-group differences of both the CHI and the BSRS-5 were significant. More types of social activities had a different engaging frequency with the 3 and 4 cutoffs. CONCLUSION: Our findings found an adequate cutoff with better differential power in the psychopathology and happiness of older people that provided a basis for application in intervention and policy formation.

BACKGROUND/PURPOSE: School-based cardiac screening is useful for identifying children and adolescents with a high risk of sudden cardiac death. However, because of challenges associated with cost, distance, and human resources, cardiac screening is not widely implemented, especially in rural areas with limited medical resources. This study aims to establish a cloud-based system suitable for mass cardiac screening of schoolchildren in rural areas with limited medical resources. METHODS: Students from three schools were included. They or their guardians completed a simple questionnaire, administered in paper or electronic form. Heart sounds were recorded using an electronic stethoscope. Twelve-lead electrocardiograms (ECGs) were recorded and digitalized. The signals were transmitted through Bluetooth to a tablet computer and then uploaded to a cloud server over Wi-Fi. Crowdsourced pediatric cardiologists reviewed those data from a web-based platform and provided remote consultation. In cases in which abnormal heart sounds or ECGs were noted, the students were referred to the hospital for further evaluation. RESULTS: A total of 1004 students were enrolled in this study. Of the 138 students referred, 62 were diagnosed as having an abnormal heart condition and most had previously been undiagnosed. The interrater agreeability was high. CONCLUSION: An innovative strategy combining a cloud-based cardiac screening system with remote consultation by crowdsourced experts was established. This system allows pediatric cardiologists to provide consultation and make reliable diagnoses. Combined with crowdsourcing, the system constitutes a viable approach for mass cardiac screening in children and adolescents living in rural areas with insufficient medical resources.

Creation of sizable subintima during intervention for chronic total occlusions (CTO) could lead to the key selection preference of metallic stents rather than bioresorbable vascular scaffolds (BVS) and then possibly deviate the outcome comparisons in real-world studies. By including recanalized CTO with true lumen tracking, we tested if any selection preference remained and compared the outcomes between everolimus-eluting stent (EES) and BVS implantation.Among 211 consecutive CTO interventions with true lumen tracking from August 2014 to April 2018 when BVS was available, we compared the clinical and interventional features between 28 patients with BVS and 77 patients with EES implantation. With propensity score matching and a median follow-up of 50.5 (37.3-60.3) months, we further assessed 25 patients with BVS and 25 with EES for target vessel failure (TVF: cardiac death, target vessel myocardial infarction, and target lesion revascularization).Multivariate analyses showed that BVS was still favored in the presence of LAD CTO (odds ratio (OR) = 3.4, 95% confidence interval (CI) = 1.0-11.7) and an average scaffold/stent size ≥ 3 mm (OR = 10.5, 95% CI = 3.0-37.3). EES was preferred for lesions with a J-CTO score ≥ 3 (OR = 19.3, 95% CI = 3.4-110.8) and multivessel intervention necessary at index procedure (OR = 11.3, 95% CI = 1.9-67.3). With matched comparisons, the TVF-free survival of EES was better than that of BVS for CTO recanalization (P = 0.049 by log-rank test) at long-term follow-up.Even with true lumen tracking techniques, selection bias remained substantial when determining either device for CTO implantation. The matched comparison of outcomes suggested the unfavorable longer-term impacts of the first generation of BVS on CTO lesions.

BACKGROUND: Although previous studies indicated the association between peripheral biomarkers and psychological conditions, a higher prevalence of cardiovascular diseases (CVD) among geriatric populations may hinder the applicability of the biomarkers. The objective of this study was to assess the adequacy of the application of biomarkers to evaluate psychological conditions among geriatric populations. METHOD: We collected information on the demographics and history of CVD in all participants. All participants completed the Brief Symptom Rating Scale (BSRS-5) and the Chinese Happiness Inventory (CHI), which are the measurement of negative and positive psychological conditions, respectively. Four indicators of the peripheral biomarkers, including the standard deviation of normal to normal RR intervals (SDNN), finger temperature, skin conductance, and electromyogram were collected for each participant during a 5-min resting state. Multiple linear regression models were conducted to evaluate the association between the biomarkers and the psychological measurements (BSRS-5, CHI) with and without the inclusion of the participants with CVD. RESULTS: A total of 233 participants without CVD (non-CVD group) and 283 participants with CVD (CVD group) were included. The CVD group was older and with higher body mass index compared to the non-CVD group. In the multiple linear regression model with all participants, only BSRS-5 scores had a positive association with electromyogram. After the exclusion of the CVD group, the association between the BSRS-5 scores and electromyogram was more relevant, while CHI scores became positively associated with SDNN. CONCLUSIONS: A single measurement of the peripheral biomarker may be insufficient to depict psychological conditions among geriatric populations.

The prevalence of heart failure is increasing, causing a tremendous burden on health care systems around the world. Although mortality rate of heart failure has been significantly reduced by several effective agents in the past 3 decades, yet it remains high in observational studies. More recently, several new classes of drugs emerged with significant efficacy in reducing mortality and hospitalization in chronic heart failure with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). To integrate these effective therapies and prioritize them in the management of Asian patients, Taiwan Society of Cardiology has recently appointed a working group to formulate a consensus of pharmacological treatment in patients with chronic heart failure. Based on most updated information, this consensus provides rationales for prioritization, rapid sequencing, and in-hospital initiation of both foundational and additional therapies for patients with chronic heart failure.
RESUMO
OBJECTIVE: Obesity is a significant risk factor for atherosclerotic cardiovascular disease; however, the "obesity paradox", in which obese patients enjoy superior survival, has been observed in various cardiovascular conditions. Whether this phenomenon exists for peripheral artery disease (PAD) remains uncertain. The goal of this study was to evaluate the relationship between body mass index (BMI) and mortality in patients with PAD. METHODS: A comprehensive literature search identified seven eligible cohort studies that reported the association between BMI and all cause mortality in patients with PAD. A dose response meta-analysis was done for all cause mortality, short term (30 day or in hospital) mortality and long term mortality. The dose response association between BMI and mortality was also assessed in patients who received endovascular therapy (EVT). RESULTS: The non-linear dose response analysis showed that higher BMI values were associated with a lower mortality risk from the range between 15 kg/m2 to approximately 33 - 34 kg/m2. The risk of mortality increased slightly thereafter. This relationship was consistent with that of long term mortality but was not apparent in short term mortality. A U shaped relationship was also observed between BMI and mortality in patients who received EVT with the lowest mortality observed at around 30 kg/m2. CONCLUSION: The obesity paradox was evident in the analysis of long term survival among patients with PAD, with the lowest mortality rates observed in obese patients. However, this association was not observed for short term or in hospital mortality.

BACKGROUND/PURPOSE: In patients with non-valvular atrial fibrillation (NVAF), the left atrial appendage occluder (LAAO) is an alternative treatment for stroke prevention. However, the long-term outcomes in Asia was generally unknown. METHODS AND RESULTS: This was a retrospective longitudinal study and a total of 124 patients with contraindications to oral anticoagulants or stroke despite under anticoagulants had been enrolled since 2013. Primary efficacy was defined as any type of stroke/systemic embolization and adverse event as any procedure or anti-thrombotic related complications. Twelve patients were excluded due to thrombus in the LAA or oversize LAA. Watchman was successfully implanted in 55 patients (98%) and ACP/Amulet also 55 patients (98%). During follow-up, the ischemic stroke rate was 1.9 in the Watchman and 1.4 per 100 patient-year in the ACP/Amulet group. There were 2 Watchman patients experiencing intracranial hemorrhage. Device-related thrombus (DRT) was noted in 3 patients (2.7%).There was no patient with peri-device lead â§5 mm. In those patients receiving only local anesthesia, the follow-up echocardiography showed no significant peri-device leak, malposition of LAAO and DRT. CONCLUSION: This long-term follow-up study shows that percutaneous closure of LAA is a safe and technically feasible procedure with satisfactory outcomes in Asia. The procedure success rate, efficacy and adverse event were similar to those reported in the Caucasian populations.

BACKGROUND/PURPOSE: Sport-specific adaptations of athlete's hearts are still under investigation. This study sought to 1) identify athlete groups with similar characteristics by clustering echocardiographic data; 2) externally validate the data-driven clusters with sport classifications of various dynamic or static loads to support the conventional hypothesis-driven approach in delineating the athlete's heart. METHODS: Anthropometric, echocardiographic and electrocardiographic assessments were collected during the 2017 Summer Universiade in Taiwan. Besides standard echocardiography and strain measurements, ventricular-arterial coupling (VAC) was assessed by the ratio of effective arterial elastance (Ea) to left ventricular end-systolic elastance (Ees) as calculated by a modified single-beat algorithm. RESULTS: We grouped 598 elite athletes (348 male, age 23 ± 2.5 years, across 24 disciplines) using Mitchell's classification. The hypothesis-driven analysis showed dynamic training-related adaptations in heart rate and morphology, including ventricular size, mass, and stroke volume. In comparison, the unsupervised approach found two clusters for each sex. Male athletes participating in high dynamic-load exercises had larger chambers, supranormal diastolic functions, depressed Ees, lower Ea and preserved optimal VAC implicating the resting status of a reservoir-rich pump, which affirmed sport-specific adaptation. The female athletes could be clustered with more noticeable functional alterations, such as depressed biventricular strain. However, the imbalanced number between clusters impeded the validation of load-related remodeling. CONCLUSION: Hierarchical clustering could analyze complicated multiparametric interactions among numerous echocardiography-derived phenotypes to discern the adaptive propensity of the athlete's heart. The endorsement or generation of hypotheses by a data-driven approach can be applied to various domains.

BACKGROUND: Bioresorbable vascular scaffold (BVS) had been implanted to several kinds of complex coronary lesions in real-world practice. We tested if long-term outcomes of BVS for complex lesions would be worse than that for relatively simple lesions. METHODS: We analyzed 457 patients (59 ± 12 years, 87% male) with 714 BVS implanted for their 529 lesions and median follow-up of 32.7 (26.8-39.3) months. Complex group (N = 284) was defined as those with BVS for acute coronary syndrome, chronic total occlusion, bifurcation/ostial lesions, instent restenosis/hybrid with metallic stents, diffuse lesions (overlapped by 2 BVS with each ⧠18 mm), venous graft/left main lesions, or lesions after rotablation. We compared their outcomes with the remaining 173 patients as non-complex group. RESULTS: The complex group had more chronic kidney disease (7% vs. 2%), multivessel disease (78% vs. 65%), use of intravascular imaging (40% vs. 23%), and more BVS (1.8 ± 0.9 vs. 1.1 ± 0.3) with longer total lengths (47 ± 22 vs. 29 ± 8 mm) implanted than non-complex group (all p < 0.05). However, the long-term target lesion revascularization (TLR) or target lesion failure (TLF) was similar (log rank p > 0.05) between the two groups. Multivariate Cox regression analyses showed BVS for ACC/AHA type C lesions was independently associated with higher risks of TLR (hazard ratio: 2.7, 95% CI = 1.1-6.6) and TLF (hazard ratio: 2.6, 95% CI = 1.1-6.3). CONCLUSION: Comparable outcomes were found between BVS for complex and non-complex lesion category. However, higher risks of TLR and TLF for type C lesions still suggested the prognostic impact of lesion complexity on long-term outcomes of BVS.

BACKGROUND: The purpose of this study was to investigate the psychopathology and level of happiness and their association with the demographic data of the older population in long-term care situations in Taiwan. METHODS: The study enrolled 500 participants who were the elderly in long-term care situations and used the Brief Symptom Rating Scale (BSRS-5) and Chinese Happiness Inventory (CHI) to determine the psychopathology and level of happiness. Multiple linear regression analysis (using a stepwise method) and a two-step cluster analysis were performed to examine the data. RESULTS: The results revealed mean scores for total CHI and total BSRS-5 of 16.08 and 2.34, respectively. Regular exercise habits, higher living expense and having a job were positively associated with happiness. Being older and living in an apartment/condominium were factors negatively associated with happiness. Living in an apartment/condominium was positively associated with a higher BSRS-5 score. Four clusters were grouped according to the variables that contributed the most: housing, exercise habits, living expense and working status. The cluster with no work, no exercise habits and lower living expense had the highest BSRS-5 score and the lowest CHI score. CONCLUSION: We concluded that the association between demographic data and happiness is stronger than the association between demographic data and psychopathology in a community sample in Taiwan. Those who have steady work, higher living expense and regular exercise habits have better happiness and less psychopathology.

BACKGROUND: A well-functioning cardiopulmonary system, which works as a pump, should generate adequate stroke volume with as little stroke work as possible. We propose a new composite parameter, right ventricular (RV) pump efficiency (η) = left ventricular stroke volume / right ventricular stroke work, to describe this idea in a volume overload population with secundum-type atrial septal defect (ASD). METHODS: We consecutively enrolled 50 patients with secundum-type ASD to investigate the relationship between right-sided volume overload and RV pump efficiency. Sixteen patients with a pulmonary to systemic flow ratio (Qp/Qs) > 1.5 underwent implantation of an occluder. The paired t test was used to compare RV pump efficiency before and after ASD closure. RESULTS: RV pump efficiency was inversely correlated with Qp/Qs and was 60 ± 20 · mmHg-1 at Qp/Qs = 1. After ASD closure, RV volume, ejection fraction and free wall strain all significantly decreased, while RV pump efficiency significantly increased from 27.4 ± 13.6 to 63.9 ± 20.4 · mmHg-1. CONCLUSIONS: RV pump efficiency can superiorly reflect the chronicity and severity of secundum-type ASD.
RESUMO
Background: Patients admitted with acute decompensated heart failure (ADHF) have a poor prognosis and poor quality of life due to dyspnea and edema. Tolvaptan, a vasopressin V2 receptor antagonist, is an effective water diuretic. This study aimed to evaluate the efficacy and safety of a short course of tolvaptan to treat volume overload in patients with ADHF. Methods: We conducted a phase III, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of a short course of tolvaptan (15 mg/day for 4 days) in hospitalized ADHF patients with volume overload despite the use of conventional diuretics. The primary end-point was the change in body weight after 4 days of treatment. The secondary end-points were the change in intake/output balance, change in serum sodium/potassium concentrations, physician/patient assessed signs and symptoms of heart failure after 4 days of treatment, and all-cause mortality in 1 month. Results: A total of 110 patients were screened, and 91 were randomized to receive 15 mg/day of tolvaptan for 4 days (n = 46) or matching placebo (n = 45). Compared to the placebo-treated patients, tolvaptan significantly reduced body weight (-1.36 ± 2.13 kg in the tolvaptan group vs. -0.59 ± 1.27 kg in the placebo group, p = 0.0394). The tolvaptan group also had a negative intake/urine volume balance compared to the placebo group (-509.3 ± 2788.2 ml vs. 975.5 ± 1903.1 ml, p = 0.0059). The safety profile of tolvaptan was acceptable. Conclusions: Tolvaptan significantly reduced volume overload in hospitalized ADHF patients with volume overload despite the use of conventional diuretics.
RESUMO
BACKGROUND AND AIMS: Elevated serum uric acid (SUA) is associated with hypertension according to its traditional definition. We investigated the association between SUA and incident hypertension according to the European Society of Cardiology (ESC) and American Society of Cardiology (ACC) guidelines. METHODS AND RESULTS: In this retrospective cohort study, we enrolled 10,537 healthy individuals ≥30 years old who underwent a routine annual health examination with office blood pressure recorded at our hospital in 2016; of the participants, 7349 repeated the exam in 2017. According to the ESC and ACC guidelines, hypertension was defined as office BP ≥ 140/90 mmHg or ≥130/80 mmHg. Hyperuricemia (HUA) was defined as SUA ≥7 mg/dL in men and ≥6 mg/dL in women. The hypertension incidence was 5.8% among 6378 individuals in the ESC cohort and 19% among 4330 individuals in the ACC cohort. Incident hypertension was significantly more common in the hyperuricemic group than in the normouricemic group (ESC: 8.6% vs. 4.7%, P < 0.001; ACC: 25.5% vs. 16.9%, P < 0.001). In the fully adjusted multivariate logistic regression analyses, each increase in SUA was associated with an increase in incident hypertension risk (ESC: adjusted OR: 1.167, 95% CI: 1.061-1.284, P = 0.001; ACC: adjusted OR: 1.125, 95% CI: 1.044-1.213, P = 0.002). The association can be explained by a significant correlation of baseline SUA with the BP in the following year (r = 0.24, P < 0.001 for baseline SUA and SBP in the following year; r = 0.239, P < 0.001 for baseline SUA and DBP in the following year). CONCLUSION: Elevated SUA was associated with incident hypertension in healthy individuals according to various contemporary BP guidelines (ClinicalTrials.gov: NCT03473951). CLINICAL TRIALS: ClinicalTrials.gov with the identification number of NCT03473951.
