ABSTRACT

Introduction: Sacubitril/valsartan, an angiotensin receptor-neprilysin inhibitor (ARNI), is superior to enalapril for chronic heart failure (CHF) with reduced ejection fraction (EF). However, its efficacy and safety in older Japanese patients in clinical practice are poorly understood. We aimed to investigate the efficacy and safety of ARNI compared with angiotensin receptor blocker (ARB) in older patients with CHF in real-world clinical practice. In addition, nutritional status and body composition were investigated as essential indicators of efficacy. Methods: This retrospective single-center observational study enrolled 55 consecutive older patients (aged ≥75 years) with CHF who received ARNI (n = 27) or ARB (n = 28) therapy between October 2020 and March 2021. Blood samples were collected before (baseline) and 4, 12, and 24 weeks after ARNI or ARB therapy initiation. Furthermore, echocardiography was performed before (baseline) and 24 weeks after ARNI or ARB therapy initiation. The efficacy endpoints were changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels, left ventricular EF, nutritional status, and body composition changes. The controlling nutritional status (CONUT) score and geriatric nutritional risk index were investigated as nutritional status indices. The safety endpoints were symptomatic hypotension, renal function exacerbation, and hyperkalemia in patients who continued ARNI or ARB therapy for >24 weeks without additional nonpharmacological treatment. Results: There were no significant changes in NT-proBNP levels and estimated glomerular filtration rates; however, there was a significant CONUT score improvement in the ARNI group (least-squares mean difference, -1.0; 95% confidence interval, -1.4 to -0.3; p = 0.04). The initial ARNI dose could not be uptitrated in five patients (19%) due to hypotension. Conclusions: ARNI exhibited significant improvement in the nutritional status in older patients with CHF compared with ARB. However, the ARNI dose should be adjusted according to the patient's blood pressure.

ABSTRACT

This study aims to clarify why the aiming method in golf putting in risky situations differs based on skill level. This study set up a difficult challenge (steep slopes and fast ball rolling greens), which required even professional golfers to change their aim. A total of 12 tour professionals and 12 intermediate amateurs were asked to perform a steep-slope task with no visual feedback of outcomes (no FB) followed by a task with visual feedback (with FB). The aim of the task was for the ball to enter the hole in one shot. Additionally, the participants were told that if the ball did not enter the hole, it was to at least stop as close to it as possible. The participant's aim (as an angle) and the kinematics of the putter head and ball were measured. The results indicated that professionals' highest ball trajectory points were significantly higher than that of amateurs, especially with FB. Additionally, professionals had higher ball-launch angles (the direction of the ball when the line connecting the ball and the center of the hole is 0 degrees) and lower peak putter head velocities than amateurs. Furthermore, the aim angle, indicating the golfer's decision-making, was higher for professionals under both conditions. However, even with FB, the amateurs' aim angles were lower and the difference between trials was smaller than that of professionals. Therefore, this study confirmed that the professionals made more drastic changes to their aim to find low-risk routes than the amateurs and that the amateurs' ability to adjust their aim was lower than that of professionals. The results suggest that the reason for the amateurs' inability to find low-risk routes lies in their decision-making. The professionals found better routes; however, there were individual differences in their routes.

ABSTRACT

BACKGROUND: Hyperpolypharmacy is associated with adverse outcomes in older adults, but because literature on its association with cardiovascular (CV) outcomes after acute decompensated heart failure (ADHF) is sparse, we investigated the relationships among hyperpolypharmacy, medication class, and death in patients with HF.Methods and Results: We evaluated the total number of medications prescribed to 884 patients at discharge following ADHF. Patients were categorized into nonpolypharmacy (<5 medications), polypharmacy (5-9 medications), and hyperpolypharmacy (≥10 medications) groups. We examined the relationship of polypharmacy status with the 2-year mortality rate. The proportion of patients taking ≥5 medications was 91.3% (polypharmacy, 55.3%; hyperpolypharmacy, 36.0%). Patients in the hyperpolypharmacy group showed worse outcomes than patients in the other 2 groups (P=0.002). After multivariable adjustment, the total number of medications was significantly associated with an increased risk of death (hazard ratio [HR] per additional increase in the number of medications, 1.05; 95% confidence interval [CI], 1.01-1.10; P=0.027). Although the number of non-CV medications was significantly associated with death (HR, 1.07; 95% CI, 1.02-1.13; P=0.01), the number of CV medications was not (HR, 1.01; 95% CI, 0.92-1.10; P=0.95). CONCLUSIONS: Hyperpolypharmacy due to non-CV medications was associated with an elevated risk of death in patients after ADHF, suggesting the importance of a regular review of the prescribed drugs including non-CV medications.

ABSTRACT

BACKGROUND: Acute decompensated heart failure (ADHF) has a poor prognosis and common comorbidities may be contributory. However, evidence for the association between dementia and clinical outcomes in patients with is sparse and it requires further investigation into risk reduction.Methods and Results: We assessed the clinical profiles and outcomes of 1,026 patients (mean age 77.8 years, 43.2% female) with ADHF enrolled in the CURE-HF registry to evaluate the relationship between investigator-reported dementia status and clinical outcomes (all-cause death, cardiovascular (CV) death, non-CV death, and HF hospitalization) over a median follow-up of 2.7 years. In total, dementia was present in 118 (11.5%) patients, who experienced more drug interruptions and HF admissions due to infection than those without dementia (23.8% vs. 13.1%, P<0.01; 11.0% vs. 6.0%, P<0.01, respectively). Kaplan-Meier analysis revealed that dementia patients had higher mortality rates than those without dementia (log-rank P<0.001). After multivariable adjustment for demographics and comorbidities, dementia was significantly associated with an increased risk of death (adjusted hazard ratio, 1.43; 95% confidence interval, 1.06-1.93, P=0.02) and non-CV death (adjusted hazard ratio, 1.65; 95% confidence interval, 1.04-2.62, P=0.03), but no significant associations between dementia and CV death or HF hospitalization were observed (both, P>0.1). CONCLUSIONS: In ADHF patients dementia was associated with aggravating factors for HF admission and elevated risk of death, primarily non-CV death.

ABSTRACT

Peripheral artery disease (PAD) is commonly caused by atherosclerosis and has an unfavorable prognosis. Complete revascularization (CR) of the coronary artery reduces the risk of major adverse cardiovascular event (MACE) in patients with coronary artery disease (CAD). However, the impact of CR in patients with PAD has not been established to date. Therefore, we evaluated the impact of CR of CAD on the five-year clinical outcomes in patients with PAD. This study was based on a prospective, multicenter, observational registry in Japan. We enrolled 366 patients with PAD undergoing endovascular treatment. The primary endpoint was MACE, defined as a composite of all-cause death, non-fatal myocardial infarction, and non-fatal stroke. After excluding ineligible patients, 96 and 68 patients received complete revascularization of the coronary artery (CR group) and incomplete revascularization of the coronary artery (ICR group), respectively. Freedom from MACE in the CR group was significantly higher than in the ICR group at 5 years (66.7% vs 46.0%, p < 0.01). Multivariate analysis revealed that CR emerged as an independent predictor of MACE (Hazard ratio: 0.56, 95% confidential interval: 0.34-0.94, p = 0.03). CR of CAD was significantly associated with improved clinical outcomes in patients with PAD undergoing endovascular treatment.

ABSTRACT

BACKGROUND: Transvenous lead extraction has been possible since the 1980s. However, complications during lead extraction, such as the distal end fragment of the lead remaining in the myocardium or venous system and injury to the veins or heart, have been reported. OBJECTIVE: The purpose of this study was to examine our method for complete removal of a separated lead, as extraction of long-term implanted devices is difficult using standard methods and may require additional procedures. The removal of leads with inner conductor coil and lead tip separated from outer insulation, conductor coil, and proximal ring electrode using a multipurpose catheter is reported. METHODS: In total, 345 consecutive patients who underwent transvenous lead extraction (TLE) from April 2014 to March 2021 were retrospectively analyzed. Lead characteristics, device type, and indications for extraction were further analyzed in 20 patients who developed separation of the proximal ring electrode and outer conductor coil from the inner conductor and distal tip at the time of extraction. RESULTS: Extractions were performed using an excimer laser sheath laser and a Byrd polypropylene telescoping sheath (n = 15); laser, Byrd polypropylene telescoping sheath, and Evolution RL (n = 2); laser and Evolution RL (n = 3); Byrd polypropylene telescoping sheath and Evolution RL (n = 1); Byrd polypropylene telescoping sheath only (n = 4); and Evolution RL only (n = 2). Twenty-seven leads implanted for more than 10 years had lead separation. A multipurpose catheter was used to protect the fragile leads from further damage. All leads were completely extracted. CONCLUSION: All distal tip-to-proximal ring electrode separated leads were successfully removed using laser and other sheaths with the assistance of a multipurpose catheter, without any part of the leads remaining in the heart.

ABSTRACT

INTRODUCTION: Data are lacking on the extent to which patients with non-valvular atrial fibrillation (AF) who are aged ≥80 years benefit from ablation treatment. The question pertains especially to patients' postablation quality of life (QoL) and long-term clinical outcomes. METHODS AND ANALYSIS: We are initiating a prospective, registry-based, multicentre observational study that will include patients aged ≥80 years with non-valvular AF who choose to undergo treatment by catheter ablation and, for comparison, such patients who do not choose to undergo ablation (either according to their physician's advice or their own preference). Study subjects are to be enrolled from 52 participant hospitals and three clinics located throughout Japan from 1 June 2022 to 31 December 2023, and each will be followed up for 1 year. The planned sample size is 660, comprising 220 ablation group patients and 440 non-ablation group patients. The primary endpoint will be the composite incidence of stroke/transient ischaemic attack (TIA) or systemic embolism (SE), another cardiovascular event, major bleeding and/or death from any cause. Other clinical events such as postablation AF recurrence, a fall or bone fracture will be recorded. We will collect standard clinical background information plus each patient's Clinical Frailty Scale score, AF-related symptoms, QoL (Five-Level Version of EQ-5D) scores, Mini-Mental State Examination (optional) score and laboratory test results, including measures of nutritional status, on entry into the study and 1 year later, and serial changes in symptoms and QoL will also be secondary endpoints. Propensity score matching will be performed to account for covariates that could affect study results. ETHICS AND DISSEMINATION: The study conforms to the Declaration of Helsinki and the Ethical Guidelines for Clinical Studies issued by the Ministry of Health, Labour and Welfare, Japan. Results of the study will be published in one or more peer-reviewed journals. TRIAL REGISTRATION NUMBER: UMIN000047023.

ABSTRACT

BACKGROUND: In adult patients, subcutaneous implantable cardioverter defibrillators (S-ICDs) have been reported to be non-inferior to transvenous ICDs with respect to the incidence of device-related complications and inappropriate shocks. Only a few reports have investigated the efficacy of S-ICDs in the pediatric field. This study aimed to investigate the utility and safety of S-ICDs in patients ≤18 years old. METHODS: This study was a multicenter, observational, retrospective study on S-ICD implantations. Patients <18 years old who underwent S-ICD implantations were enrolled. The detailed data on the device implantations and eligibility tests, incidence of appropriate- and inappropriate shocks, and follow-up data were assessed. RESULTS: A total of 62 patients were enrolled from 30 centers. The patients ranged in age from 3 to 18 (median 14 years old [IQR 11.0-16.0 years]). During a median follow up of 27 months (13.3-35.8), a total of 16 patients (26.2%) received appropriate shocks and 13 (21.3%) received inappropriate shocks. The common causes of the inappropriate shocks were sinus tachycardia (n = 4, 30.8%) and T-wave oversensing (n = 4, 30.8%). In spite of the physical growth, the number of suitable sensing vectors did not change during the follow up. No one had any lead fractures or device infections in the chronic phase. CONCLUSIONS: Our study suggested that S-ICDs can prevent sudden cardiac death in the pediatric population with a low incidence of lead complications or device infections. The number of suitable sensing vectors did not change during the patients' growth.

ABSTRACT

For motor tasks that require fine-tuning, such as adjusting the applied force according to the distance to the target, as required for driving and putting in golf, it is important to develop a high degree of sensitivity of one's movement-produced feedback. In previous research focusing on mental representation in golf, this ability to control distance has been called "a sense of distance". In particular, this study focused on three skills: motor control of the putter head, perception of the impact force, and prediction of the ball's travel distance. However, the relationship between the motor control of the putter head and the error of the outcome estimation is yet to be clarified. The purpose of the present study is two-fold: first, to clarify whether kinematic variation of putter head is correlated with error in estimating the outcome and, second, to quantitatively evaluate the performer's sensations of good and poor performance generated by the ball's impact, for a comparison of the kinematics and impact force of the putter head based on their assessment. Twelve professionals and 12 intermediate amateurs played two distance targets (at 2.4 and 4.8 m) without visual feedback of the outcomes. The kinematics of the putter head, impact force, final ball position, outcome estimation, and subjective assessment were measured. Our results show that the variability in the peak velocity was moderately correlated with the error of the outcome estimation in amateurs' 4.8-m putting task. In addition, amateurs estimated undershoots (overshoots) when they provided worse (better) evaluations. However, the amateurs' trials that were rated as better putts were actually overshoots. These results suggest that the subjectively "good putt" of amateurs was not physically good, and the amateurs putted hard to compensate for the risk of undershoots. However, no remarkable feature of the professional's sense of distance was found. This suggests that professional golfers' sensation is not significantly different from the outcomes that can be physically detected.

ABSTRACT

BACKGROUND: Deep vein thrombosis with arteriovenous fistulas is rare, with few therapeutic options available for chronic-phase deep vein thrombosis. Moreover, the effectiveness of endovascular treatment for chronic-phase deep vein thrombosis with arteriovenous fistulas has not been established. We describe herein a case of successful endovascular treatment for chronic deep vein thrombosis with multiple arteriovenous fistulas. CASE PRESENTATION: We describe the case of a 72-year-old Asian woman who had begun experiencing left leg swelling and intermittent claudication 2 years prior. Enhanced computed tomography revealed left common iliac vein occlusion with vein-to-vein collateral formation and several arteriovenous fistulas. Angiography and ultrasound showed the arteriovenous fistulas to run from the common and internal iliac arteries to the external iliac and superficial femoral veins. We opted against surgical repair for the arteriovenous fistulas due to their complex nature and complicated morphology. Since her condition was progressive, endovascular treatment with a stent graft was performed for the deep vein thrombosis, after which her symptoms gradually improved. Four months following the procedure, enhanced computed tomography confirmed remarkable reduction of the vein-to-vein collaterals and arteriovenous fistulas. CONCLUSIONS: In the present case, enhanced computed tomography with a stent graft was effective in improving symptoms. This strategy may therefore be a treatment option for intractable chronic deep vein thrombosis with arteriovenous fistulas.

ABSTRACT

BACKGROUND: Transvenous lead extraction (TLE) is an established procedure for the management of cardiovascular implantable electronic devices. However, some difficulties and risks of complications still exist, especially in old and adhered leads. Evolution RL (Cook Medical, Bloomington, IN, USA) is a newly introduced device for TLE; however, no clinical results have been reported in Japan, and the results with older leads are unknown. We investigated the efficacy and safety of Evolution RL and its usefulness for old leads at two TLE centers in Japan. METHODS: A total of 27 consecutive patients who underwent lead extraction using Evolution RL at Shinshu University Hospital and Tokyo Women's Medical University Hospital from September 2017 to December 2019 were retrospectively enrolled. We examined the backgrounds of the patients and leads and investigated the efficacy and safety of the procedures. We divided the leads into two groups according to the number of years of implantation (10 years) and compared the results. RESULTS: Among the 27 patients, 20 (74.1%) were men, and the median age was 62 (14-91) years. The total number of leads was 58, and the median implantation duration was 136 months (8-448). We achieved clinical success in all patients and complete procedural success in 24 patients (88.9%). In three patients, the broken tip of the lead remained in the heart. No major complications were noted. Of the 58 leads, there were 34 leads with more than 10 years of implantation, with significantly more Evolution RLs used (94.1% vs. 54.2%, p = 0.001) and significantly higher percentages of Evolution 11Fr, 13Fr, and steady sheaths used (79.4% vs. 33.3%, p = 0.001, 52.9% vs. 16.7%, p = 0.006, and 64.7% vs. 20.8%, p = 0.001, respectively). CONCLUSIONS: In two TLE centers in Japan, Evolution RL was shown to be safe and effective, even in leads older than 10 years.

ABSTRACT

Heart failure with preserved ejection fraction (HFpEF) has currently become a major concern in the aging society owing to its substantial and growing prevalence. Recent investigations regarding sacubitril/valsartan have suggested that there is a gender difference in the efficacy of the medication in HFpEF cohort. However, information of gender difference in clinical profiles, examination, and prognosis have not been well investigated. The present study aimed to evaluate the differences in baseline characteristics and outcomes between women and men in a Japanese HFpEF cohort. We analyzed the data from our prospective, observational, and multicenter cohort study. Overall, 1036 consecutive patients hospitalized for acute decompensated heart failure were enrolled. We defined patients with an ejection fraction (EF) of ≥ 50% as HFpEF. Patients with severe valvular disease were excluded; the remaining 379 patients (women: n = 201, men: n = 178) were assessed. Women were older than men [median: 85 (79-89) years vs. 83 (75-87) years, p = 0.013]. Diabetes mellitus, hyperuricemia, and coronary artery disease were more prevalent in men than in women (34.8% vs. 23.9%, p = 0.019, 23.6% vs. 11.4%, p = 0.002, and 23.0% vs. 11.9%, p = 0.005, respectively). EF was not significantly different between women and men. The cumulative incidence of cardiovascular death or hospitalization for congestive heart failure (CHF) was significantly lower in women than in men (log-rank p = 0.040). Women with HFpEF were older and less often exhibited an ischemic etiology; further, they were associated with a lower risk for cardiovascular death or hospitalization for CHF compared with men in the Japanese population.

ABSTRACT

Endovascular treatment (EVT) is the main treatment for peripheral artery disease (PAD). Despite advances in device development, the restenosis rate remains high in patients with femoropopliteal lesions (FP). This study aimed to evaluate the effectiveness of exercise training in reducing the 1-year in-stent restenosis rate of bare metal nitinol stents for FPs. This prospective, randomized, open-label, multicenter study was conducted from January 2017 to March 2019. We randomized 44 patients who had claudication with de novo stenosis or occlusion of the FP into an intensive exercise group (n = 22) and non-intensive exercise group (n = 22). Non-intensive exercise was defined as walking for less than 30 min per session, fewer than three times a week. We assessed exercise tolerance using an activity meter at 1, 3, 6, and 12 months, and physiotherapists ensured maintenance of exercise quality every month. The primary endpoint was instant restenosis defined as a peak systolic velocity ratio > 2.5 on duplex ultrasound imaging. Kaplan-Meier analysis was used to evaluate the data. There were no significant differences in background characteristics between the groups. Six patients dropped out of the study within 1 year. In terms of the primary endpoint, intensive exercise significantly improved the patency rate of bare nitinol stents at 12 months. The 1-year freedom from in-stent restenosis rates were 81.3% in the intensive exercise group and 47.6% in the non-intensive exercise group (p = 0.043). No cases of stent fracture were observed in the intensive exercise group. Intensive exercise is safe and reduces in-stent restenosis in FP lesions after endovascular therapy for PAD. Clinical trial registration: University Hospital Medical Information Network Clinical Trials Registry (No. UMIN 000025259).

ABSTRACT

OBJECTIVE: This study was designed to evaluate the cariogenic potential of Lactobacillus gasseri YIT 12321. DESIGN: L. gasseri YIT 12321 was isolated from the human oral cavity as a probiotic candidate strain. Three types of experimental biofilm formations on bovine enamel specimens were assessed using Streptococcus sobrinus ATCC 33478, L. gasseri YIT 12321, and a co-culture of S. sobrinus and L. gasseri YIT 12321 in vitro. L. gasseri YIT 12321 was analyzed for its ability to utilize seven carbohydrates. L. gasseri YIT 12321 was cultured in tryptic soy broth without dextrose and containing a test carbohydrate at 37 °C for 16 h. RESULTS: The decrease in pH in the region under the biofilm produced by L. gasseri YIT 12321 was unusually slow, and the pH was maintained above 5.5 for 16 h. The amount of biofilm and the reduction in enamel hardness were minimal in the L. gasseri YIT 12321 group among the three experimental groups. The amount of co-culture-derived biofilms was less than that of S. sobrinus biofilms. When S. sobrinus was grown using sucrose, the pH decreased to 3.98. In contrast, L. gasseri YIT 12321 cultures maintained the pH above the critical pH for dentin demineralization. CONCLUSIONS: L. gasseri YIT 12321 is suggested to have a low cariogenic potential. The application of this strain as a probiotic may contribute to oral safety.

ABSTRACT

(1) Background: The aim of this study was to assess the preventive effect of tooth surface disinfection treatment, in addition to fluoride application, during fixed orthodontic treatment. (2) Methods: An open label randomized control trial for the evaluation of the dental caries preventive procedure was performed for the patients with high caries risk who had been visited at Department of Orthodontics, Tsurumi University Dental Hospital for orthodontics treatment. The follow-up period was six months. White spot lesions (WSLs) were evaluated by quantitative light-induced fluorescence (QLF). Cariogenic bacteria were monitored and evaluated by bacterial culture. In addition, the oral microbiome was evaluated by a next-generation sequence (NGS). (3) Results: By the mixed effect modeling, tooth surface disinfection treatment significantly reduced cariogenic bacteria and all parameters obtained by QLF. (4) Conclusions: Tooth surface disinfection treatment, in addition to PMTC and fluoride application, were effective for dental caries prevention and keeping a healthy microbiome during orthodontic treatment.

ABSTRACT

Although high thromboembolic risk was assumed in elderly patients with heart failure (HF) and atrial fibrillation (AF), inadequate control of prothrombin time/international normalized ratio was often observed in patients using vitamin K antagonists (VKAs). We hypothesized that patients treated with direct oral anticoagulants (DOAC) would have a better outcome than those treated with VKAs. The aim of this study was to compare the efficacies of DOACs and VKAs in elderly patients with HF and AF. We retrospectively analyzed data from a multicenter, prospective observational cohort study. A total of 1036 patients who were hospitalized for acute decompensated HF were enrolled. We assessed 329 patients aged > 65 years who had non-valvular AF and divided them into 2 groups according to the anticoagulant therapy they received. A subgroup analysis was performed using renal dysfunction based on estimated glomerular filtration rate (eGFR; mL/min/1.73 m2). The primary outcome was all-cause mortality, and the secondary outcomes were non-cardiovascular death or stroke. The median follow-up period was 730 days (range 334-1194 days). The primary outcome was observed in 84 patients; non-cardiovascular death, in 25 patients; and stroke, in 14 patients. The Kaplan-Meier analysis revealed that all-cause mortality was significantly lower in the DOAC group than in the VKA group (log-rank p = 0.033), whereas the incidence rates of non-cardiovascular death (log-rank p = 0.171) and stroke (log-rank p = 0.703) were not significantly different in the crude population. DOAC therapy was not associated with lower mortality in the crude population (log-rank p = 0.146) and in the eGFR ≥ 45 mL/min/1.73 m2 subgroup (log-rank p = 0.580). However, DOAC therapy was independently associated with lower mortality after adjustments for age, diabetes mellitus, and albumin level (hazard ratio, 0.55; 95% confidence interval, 0.30-0.99; p = 0.045) in the eGFR < 45 mL/min/1.73 m2 subgroup. Compared with VKA therapy, DOAC therapy was associated with lower risk of all-cause mortality in the elderly HF patients with AF and renal dysfunction.

ABSTRACT

We investigated the prognostic effects of hyperuricemia and high or low body mass index (BMI) in peripheral artery disease (PAD) after endovascular therapy (EVT). Between July 2015-2016, 357 consecutive patients with PAD who underwent EVT were enrolled. Patients were divided into 2 groups: BMI < 25 kg/m2 (low BMI) and ≥ 25 kg/m2 (high BMI); they were also divided into 2 more groups based on the presence/absence of hyperuricemia. The primary and secondary endpoints were major adverse cardiovascular and limb events (MACLE), and all-cause death at 3 years post-EVT. Patients with hyperuricemia had significantly lower freedom from MACLE than patients without hyperuricemia at 3 years (57.0 vs 71.9%, p = .0068). The overall survival of patients with hyperuricemia was significantly lower than that of patients without hyperuricemia (63.9 vs 81.7%, p = .0012). Patients with hyperuricemia who had low BMI experienced significantly lower freedom from MACLE than those without hyperuricemia who had low BMI (48.2 vs 69.9%, p = .002). The overall survival of patients with hyperuricemia who had low BMI was significantly lower than that of patients without hyperuricemia who had low BMI (55.2 vs 77.1%, p = .003). Patients with hyperuricemia had significantly more MACLE and a lower survival at 3 years than patients without hyperuricemia, even if they had a low BMI.
