FHL2 in arterial medial calcification in chronic kidney disease.

BACKGROUND AND HYPOTHESIS: Arterial medial calcification (AMC) is a common complication in individuals with chronic kidney disease (CKD), which can lead to cardiovascular morbidity and mortality. The progression of AMC is controlled by a key transcription factor called runt-related transcription factor 2 (RUNX2), which induces vascular smooth muscle cells (VSMCs) transdifferentiation into a osteogenic phenotype. However, RUNX2 has not been targeted for therapy due to its essential role in bone development. The objective of our study was to discover a RUNX2 coactivator that is highly expressed in arterial VSMCs as a potential therapy for AMC. METHODS: We employed transcriptomic analysis of human data and an animal reporter system to pinpoint FHL2 as a potential target. Subsequently, we investigated the mRNA and protein expression patterns of FHL2 in the aortas of both human and animal subjects with CKD. To examine the role of FHL2 in the RUNX2 transcription machinery, we conducted coimmunoprecipitation (Co-IP) and chromatin immunoprecipitation (ChIP) experiments. Next, we manipulated FHL2 expression in cultured VSMCs to examine its impact on high phosphate-induced transdifferentiation. Finally, we employed FHL2 null mice to confirm the role of FHL2 in the development of AMC in vivo. RESULTS: Among all the potential RUNX2 cofactor, FHL2 displays selective expression within the cardiovascular system. In the context of CKD subjects, FHL2 undergoes upregulation and translocation from the cytosol to the nucleus of arterial VSMCs. Once in the nucleus, FHL2 interacts structurally and functionally with RUNX2, acting as a coactivator of RUNX2. Notably, the inhibition of FHL2 expression averts transdifferentiation of VSMCs into an osteogenic phenotype and mitigates aortic calcification in uremic animals, without causing any detrimental effects on the skeletal system. CONCLUSION: These observations provide evidence that FHL2 is a promising target for treating arterial calcification in patients with CKD.

Representativeness of the PIONEER-HF and PARAGLIDE-HF in patients hospitalized with acute heart failure.

AIMS: The PIONEER-HF and PARAGLIDE-HF trials aimed to determine the efficacy and safety of the in-hospital initiation of sacubitril/valsartan in patients hospitalized for AHF. However, whether the inclusion and exclusion criteria of the trials apply to patients encountered in real-world routine care is unclear. This study aimed to investigate the applicability of the PIONEER-HF and PARAGLIDE-HF trials to real-world AHF patients. METHODS AND RESULTS: We identified 28 293 AHF hospitalized patients between August 2008 to August 2017 from the Chang Gung Research Database and classified them into four groups based on left ventricular ejection fraction (LVEF) and trial criteria. Cox proportional hazards models were used to compare the risk of HF hospitalization and cardiovascular (CV) death. We defined PIONEER-HF eligible (n = 3683) and non-eligible (n = 3502) patients with an LVEF ≤40%, and PARAGLIDE-HF eligible (n = 5191) and non-eligible (n = 5832) patients with an LVEF >40%. Over a mean follow-up of 3.5 years, the PIONEER-HF non-eligible and eligible groups exhibited similar rates of HF hospitalization and CV death (41.1% vs. 41.8%, adjusted hazard ratio [aHR]: 0.95; 95% CI: 0.88-1.04). No significant difference was found in the composite outcome between PARAGLIDE-HF non-eligible and eligible groups (36.7% vs. 38.6%; aHR: 0.97; 95% CI: 0.90-1.04). CONCLUSIONS: Using trial criteria, only 31.3% of AHF patients were eligible for sacubitril-valsartan. Yet, non-eligible patients demonstrated similar outcomes to eligible patients, indicating a need for further evaluation of sacubitril-valsartan benefits in non-eligible AHF patients.

Syphilis and cardiovascular risk: a Taiwanese registry.

BACKGROUND AND AIMS: Studies on the impact of syphilis on the cardiovascular system in large populations are limited. This study investigated the effects of syphilis on cardiovascular outcomes. METHODS: Medical records from 2010 to 2015 were retrieved from the Taiwan National Health Insurance Research Database, linked to the Notifiable Infectious Diseases database from the Taiwan Centers for Disease Control. Patients with syphilis were identified, excluding those with missing information, under 20 years of age, or with a history of human immunodeficiency virus infection, acute myocardial infarction, heart failure, aortic regurgitation, replacement of the aortic valve, aneurysm and/or dissection of the aorta, atrial fibrillation, ischaemic stroke, haemorrhagic stroke, and venous thromboembolism. Primary outcomes included new-onset acute myocardial infarction, heart failure, aortic regurgitation, aneurysm and dissection of the aorta, atrial fibrillation, ischaemic stroke, haemorrhagic stroke, venous thromboembolism, cardiovascular death, and all-cause mortality. RESULTS: A total of 28 796 patients with syphilis were identified from 2010 to 2015. After exclusions and frequency matching, 20 601 syphilis patients and 20 601 non-syphilis patients were analysed. The relative rate (RR) was utilized in the analysis, as the competing risk of death was not considered. Compared with patients without syphilis, patients with syphilis had increased risks of acute myocardial infarction (RR 38%, 95% confidence interval [CI] 1.19-1.60, P < .001), heart failure (RR 88%, 95% CI 1.64-2.14, P < .001), aortic regurgitation (RR 81%, 95% CI 1.18-2.75, P = .006), atrial fibrillation (RR 45%, 95% CI 1.20-1.76, P < .001), ischaemic stroke (RR 68%, 95% CI 1.52-1.87, P < .001), haemorrhagic stroke (RR 114%, 95% CI 1.74-2.64, P < .001), venous thromboembolism (RR 67%, 95% CI 1.23-2.26, P = .001), cardiovascular death (RR 155%, 95% CI 2.11-3.08, P < .001), and all-cause death (RR 196%, 95% CI 2.74-3.19, P < .001) but not for aneurysm and dissection of the aorta. CONCLUSIONS: This study demonstrates that patients with syphilis have a higher risk of cardiovascular events and all-cause mortality compared with those without syphilis.

Early Surgery for Infective Endocarditis Complicated With Neurologic Injury.

OBJECTIVES: To estimate the association between early surgery and the risk of mortality in patients with left-sided infective endocarditis in the context of stroke. DESIGN: Retrospective cohort study. SETTING: This study was a multiinstitution study based on the Chang Gung Research Database, which contains electronic medical records from 7 hospitals in northern and southern Taiwan; these include 2 medical centers, 2 regional hospitals, and 3 district hospitals. PARTICIPANTS: Patients with active left-sided infective endocarditis who underwent valve surgery between September 2002 and December 2018. INTERVENTIONS: The authors divided patients into 2 groups, with versus without preoperative neurologic complications, had undergone early (within 7 d) or later surgery, and with brain ischemia or hemorrhage. MEASUREMENTS AND MAIN RESULTS: Three hundred ninety-two patients with a median time from diagnosis to surgery of 6 days were included. No significant differences in postoperative stroke, in-hospital mortality, or follow-up outcomes were observed between the patients with and without neurologic complications. Among the patients with preoperative neurologic complications, patients who underwent early surgery had a lower 30-day postoperative mortality rate (13.1% v 25.8%; hazard ratio, 0.21; 95% CI 0.07-0.67). In the subgroup analysis of the comparison between brain ischemia and hemorrhage groups, there was no significant between-group difference in the in-hospital outcomes or outcomes after discharge. CONCLUSIONS: Early cardiac surgery may be associated with more favorable clinical outcomes in patients with preoperative neurologic complications. Thus, preoperative neurologic complications should not delay surgical interventions.

Efficacy of Sacubitril-Valsartan on Survival and Cardiac Remodeling in Hypotensive Heart Failure With Reduced Ejection Fraction: A Multicenter Study.

OBJECTIVE: To investigate whether hypotensive patients diagnosed with heart failure and reduced ejection fraction (HFrEF) might benefit from angiotensin receptor-neprilysin inhibitors (ARNis) in real-world practice because patients with baseline systolic blood pressure (SBP) of less than 100 mm Hg have been excluded from landmark trials. PATIENTS AND METHODS: In this multicenter study conducted between January 1, 2013, and December 31, 2021, a total of 7562 symptomatic patients with HFrEF were enrolled and grouped by SBP (hypotension was defined as an SBP of less than 100 mm Hg) and ARNi use as follows: group 1, hypotensive/non-ARNi users (n=484); group 2, hypotensive/ARNi users (n=308); group 3, nonhypotensive/non-ARNi users (n=4560); and group 4, nonhypotensive/ARNi users (n=2210). Inverse probability of treatment weighting was used to balance baseline characteristics for survival analysis. RESULTS: Diverse baseline characteristics and lower rates of medication use were found among non-ARNi users compared with ARNi users. Hypotensive/ARNi users had lower ARNi initiation doses than nonhypotensive/ARNi users. We observed significantly lower mortality, composite heart failure hospitalization, and CV death for hypotensive/ARNi and the other 2 nonhypotensive groups (groups 3 and 4) during a median follow-up of 3.43 years (all P<.05), with a similar effect on reverse remodeling for the hypotensive/ARNi group compared with the hypotensive/non-ARNi group. The event-free survival benefits of ARNi vs renin-angiotensin system inhibitors were consistent with the lower boundary of SBP for clinical benefits found until 88 mm Hg (spline curves) after inverse probability of treatment weighting. CONCLUSION: Patients with HFrEF and hypotension may still benefit from ARNi treatment. Patients with hypotensive HFrEF should not be routinely excluded from ARNi use in a real-world setting.

Effects of mitral valve disease etiology on the outcomes of mechanical and biological valve replacement: retrospective cohort study.

INTRODUCTION: The choice of an artificial mitral valve (MV) is a crucial clinical decision that affects the long-term survival and quality of life of patients. However, current guidelines recommend selecting MV based on patient age and life expectancy at the time of MV replacement (MVR), without considering the etiology of MV disease. This study aimed to investigate whether MV disease etiology should be considered when choosing a valve for MVR and to evaluate the impact of MV disease etiology on long-term patient survival. METHODS: Using data (2002 to 2018) from Taiwan's National Health Insurance Research Database, we conducted a nationwide retrospective cohort study to compare the biological and mechanical valves in terms of all-cause mortality as the primary outcome. The inverse probability of the treatment weighting method was used to reduce the effects of the confounding factors. The following etiologies were assessed: infective endocarditis (IE), rheumatic heart disease (RHD), ischemic mitral regurgitation (IMR), and degenerative mitral regurgitation (DMR). RESULTS: In patients aged <70 years, it was observed that mechanical valves demonstrated an association with benefits compared to biological valves in the context of survival. In patients with IE aged <72 years, mechanical valves were associated with survival benefits, but not in those with stroke during hospitalization. These valves were also found to be linked with survival advantages for patients with RHD aged <60 years and for those with DMR aged < 72 years. However, no age-dependent effects of valve type on all-cause mortality were observed in patients with IMR. CONCLUSION: The etiology of MV disease appears to be important in the selection of a suitable MV and determination of a cutoff age for mechanical and biological MVR.

Urinary cadmium concentration is associated with the severity and clinical outcomes of COVID-19: a bicenter observational cohort study.

BACKGROUND: Cadmium and nickel exposure can cause oxidative stress, induce inflammation, inhibit immune function, and therefore has significant impacts on the pathogenesis and severity of many diseases. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can also provoke oxidative stress and the dysregulation of inflammatory and immune responses. This study aimed to assess the potential associations of cadmium and nickel exposure with the severity and clinical outcomes of patients with coronavirus disease 2019 (COVID-19). METHODS: We performed a retrospective, observational, bicenter cohort analysis of patients with SARS-CoV-2 infection in Taiwan between June 2022 and July 2023. Cadmium and nickel concentrations in blood and urine were measured within 3 days of the diagnosis of acute SARS-CoV-2 infection, and the severity and clinical outcomes of patients with COVID-19 were analyzed. RESULTS: A total of 574 patients were analyzed and divided into a severe COVID-19 group (hospitalized patients) (n = 252; 43.9%), and non-severe COVID-19 group (n = 322; 56.1%). The overall in-hospital mortality rate was 11.8% (n = 68). The severe COVID-19 patients were older, had significantly more comorbidities, and significantly higher neutrophil/lymphocyte ratio, C-reactive protein, and interleukin-6 than the non-severe COVID-19 patients (all p < 0.05). Blood and urine cadmium and urine nickel concentrations were significantly higher in the severe COVID-19 patients than in the non-severe COVID-19 patients. Among the severe COVID-19 patients, those in higher urine cadmium/creatinine quartiles had a significantly higher risk of organ failure (i.e., higher APACHE II and SOFA scores), higher neutrophil/lymphocyte ratio, lower PaO2/FiO2 requiring higher invasive mechanical ventilation support, higher risk of acute respiratory distress syndrome, and higher 60-, 90-day, and all-cause hospital mortality (all p < 0.05). Multivariable logistic regression models revealed that urine cadmium/creatinine was independently associated with severe COVID-19 (adjusted OR 1.643 [95% CI 1.060-2.547], p = 0.026), and that a urine cadmium/creatinine value > 2.05 µg/g had the highest predictive value (adjusted OR 5.349, [95% CI 1.118-25.580], p = 0.036). CONCLUSIONS: Urine cadmium concentration in the early course of COVID-19 could predict the severity and clinical outcomes of patients and was independently associated with the risk of severe COVID-19.

Clinical significance of regional constructive and wasted work in patients receiving cardiac resynchronization therapy.

Background: Previous studies have shown that global constructive work (CW) and wasted work (WW) predict response to cardiac resynchronization therapy (CRT). This study evaluated the predictive value of regional CW and WW for reverse remodeling and clinical outcomes after CRT. Methods: We performed a prospective study involving 134 CRT candidates with left bundle branch block and left ventricular ejection fraction ≤35%. Global and regional CW and WW were calculated using pressure-strain loop analysis. CRT response was defined by reverse remodeling as a reduction of ≥15% in left ventricular end-systolic volume after six months. Results: At six-month follow-up, 92 (69%) patients responded to CRT. Of the regional CW and WW measures, lateral wall (LW) CW and septal WW were most strongly and significantly correlated with reverse remodeling. At multivariate analysis, LW CW and septal WW were both independent determinants of reverse remodeling. When LW CW and septal WW were included in the model, global CW and WW were not independently associated with reverse remodeling. LW CW and septal WW predicted reverse remodeling with an area under the curve (AUC) of 0.783 (95% CI: 0.700-0.866) and 0.737 (95% CI: 0.644-0.831), respectively. Using both variables increased the AUC to 0.832 (95% CI: 0.755-0.908). Both LW CW ≤878 mmHg% (HR 2.01; 95% CI: 1.07-3.79) and septal WW ≤181 mmHg% (HR 2.60; 95% CI: 1.38-4.90) were significant predictors of combined death and HF hospitalization at two-year follow-up. Conclusion: LW CW and septal WW before CRT are important determinants of reverse remodeling and clinical outcomes.

Identification of Endothelial Cell Protein C Receptor by Urinary Proteomics as Novel Prognostic Marker in Non-Recovery Kidney Injury.

Acute kidney injury is a common and complex complication that has high morality and the risk for chronic kidney disease among survivors. The accuracy of current AKI biomarkers can be affected by water retention and diuretics. Therefore, we aimed to identify a urinary non-recovery marker of acute kidney injury in patients with acute decompensated heart failure. We used the isobaric tag for relative and absolute quantification technology to find a relevant marker protein that could divide patients into control, acute kidney injury with recovery, and acute kidney injury without recovery groups. An enzyme-linked immunosorbent assay of the endothelial cell protein C receptor (EPCR) was used to verify the results. We found that the EPCR was a usable marker for non-recovery renal failure in our setting with the area under the receiver operating characteristics 0.776 ± 0.065; 95%CI: 0.648-0.905, (p < 0.001). Further validation is needed to explore this possibility in different situations.

Fibrate and the risk of cardiovascular disease among moderate chronic kidney disease patients with primary hypertriglyceridemia.

Introduction: Hypertriglyceridemia is the most prevalent dyslipidemia in patients with chronic kidney disease (CKD). However, research about fibrate treatment in CKD patients is limited, and assessing its benefits becomes challenging due to the frequent concurrent use of statins. Thus, this study is aimed to investigate the role of fibrate in CKD stage 3 patients with hypertriglyceridemia who did not receive other lipid-lowering agents. Methods: This study enrolled patients newly diagnosed CKD3 with LDL-C<100mg/dL and had never received statin or other lipid-lowering agents from Chang Gung Research Database. The participants were categorized into 2 groups based on the use of fibrate: fibrate group and non-fibrate group (triglyceride >200mg/dL but not receiving fibrate treatment). The inverse probability of treatment weighting was performed to balance baseline characteristics. Results: Compared with the non-fibrate group (n=2020), the fibrate group (n=705) exhibited significantly lower risks of major adverse cardiac and cerebrovascular events (MACCEs) (10.4% vs. 12.8%, hazard ratios [HRs]: 0.69, 95% confidence interval [CI]: 0.50 to 0.95), AMI (2.3% vs. 3.9%, HR: 0.52, 95% CI: 0.37 to 0.73), and ischemic stroke (6.3% vs. 8.0%, HR: 0.67, 95% CI: 0.52 to 0.85). The risk of all-cause mortality (5.1% vs. 4.5%, HR: 1.09, 95% CI: 0.67 to 1.79) and death from CV (2.8% vs. 2.3%, HR: 1.07, 95% CI: 0.29 to 2.33) did not significantly differ between the 2 groups. Conclusion: This study suggests that, in moderate CKD patients with hypertriglyceridemia but LDL-C < 100mg/dL who did not take other lipid-lowering agents, fibrates may be beneficial in reducing cardiovascular events.

Sex Differences in Epidemiological Distribution and Outcomes of Surgical Mitral Valve Disease.

BACKGROUND: Mitral valve (MV) disease is the most common form of valvular heart disease. Findings that indicate women have a higher risk for unfavorable outcomes than men remain controversial. This study aimed to determine the sex-based differences in epidemiological distributions and outcomes of surgery for MV disease.Methods and Results: Overall, 18,572 patients (45.3% women) who underwent MV surgery between 2001 and 2018 were included. Outcomes included in-hospital death and all-cause mortality during follow up. Subgroup analysis was conducted across different etiologies, including infective endocarditis (IE), degenerative, ischemic, and rheumatic mitral pathology. The overall MV repair rate was lower in women than in men (20.5% vs. 30.6%). After matching, 6,362 pairs (woman : man=1 : 1) of patients were analyzed. Women had a slightly higher risk for in-hospital death than men (10.8% vs. 9.8%; odds ratio [OR]: 1.11, 95% confidence interval [CI]: 0.99-1.24; P=0.075). Women tended to have a higher incidence of de novo dialysis (9.8% vs. 8.6%; P=0.022) and longer intensive care unit stay (8 days vs. 7.1 days; P<0.001). Women with IE had poorer in-hospital outcomes than men; however, there were no sex differences in terms of all-cause mortality. CONCLUSIONS: Sex-based differences of MV intervention still persist. Although long-term outcomes were comparable between sexes, women, especially those with IE, had worse perioperative outcomes than men.

Mitral Valve Repair vs. Replacement by Different Etiologies　- A Nationwide Population-Based Cohort Study.

BACKGROUND: When mitral valve (MV) surgery is indicated, repair is preferred over replacement; however, this preference is not supported by evidence from clinical trials. Furthermore, the benefits of MV repair may not be universal for all etiologies of MV disease.Methods and Results: This study identified a total of 18,428 patients who underwent MV repair (n=4,817) or MV replacement (n=13,611) during 2001-2018 from Taiwan's National Health Insurance Research Database. These patients were classified into 4 etiologies: infective endocarditis (IE, n=2,678), rheumatic heart disease (RHD, n=4,524), ischemic mitral regurgitation (IMR, n=3,893), and degenerative mitral regurgitation (DMR, n=7,333). After propensity matching, all-cause mortality during follow-up was lower among patients receiving MV repair than among patients receiving MV replacement in the IE, IMR, and DMR groups (hazard ratio [HR]=0.72, 95% confidence interval [CI]: 0.55-0.93; HR=0.82, 95% CI: 0.73-0.92; and HR 0.73, 95% CI: 0.64-0.84, respectively). However, in the RHD group, the MV reoperation rate was higher after MV repair than after MV replacement (subdistribution HR=1.91, 95% CI: 1.02-3.55). CONCLUSIONS: In comparison with MV replacement, MV repair was associated with a lower late mortality in patients with IE, IMR, and DMR, and a higher risk of reoperation in patients with RHD.

Contactless Blood Pressure Measurement Via Remote Photoplethysmography With Synthetic Data Generation Using Generative Adversarial Networks.

Remote photoplethysmography (rPPG) has been used to measure vital signs such as heart rate, heart rate variability, blood pressure (BP), and blood oxygen. Recent studies adopt features developed with photoplethysmography (PPG) to achieve contactless BP measurement via rPPG. These features can be classified into two groups: time or phase differences from multiple signals, or waveform feature analysis from a single signal. Here we devise a solution to extract the time difference information from the rPPG signal captured at 30 FPS. We also propose a deep learning model architecture to estimate BP from the extracted features. To prevent overfitting and compensate for the lack of data, we leverage a multi-model design and generate synthetic data. We also use subject information related to BP to assist in model learning. For real-world usage, the subject information is replaced with values estimated from face images, with performance that is still better than the state-of-the-art. To our best knowledge, the improvements can be achieved because of: 1) the model selection with estimated subject information, 2) replacing the estimated subject information with the real one, 3) the InfoGAN assistance training (synthetic data generation), and 4) the time difference features as model input. To evaluate the performance of the proposed method, we conduct a series of experiments, including dynamic BP measurement for many single subjects and nighttime BP measurement with infrared lighting. Our approach reduces the MAE from 15.49 to 8.78 mmHg for systolic blood pressure (SBP) and 10.56 to 6.16 mmHg for diastolic blood pressure(DBP) on a self-constructed rPPG dataset. On the Taipei Veterans General Hospital(TVGH) dataset for nighttime applications, the MAE is reduced from 21.58 to 11.12 mmHg for SBP and 9.74 to 7.59 mmHg for DBP, with improvement ratios of 48.47% and 22.07% respectively.

Outcomes of Endovascular Treatment for Infective Aortic Aneurysms　- A Multicenter Retrospective Study.

BACKGROUND: In Taiwan, infective native aortic aneurysms (INAAs) are relatively common, so the aim of present study was to demonstrate the comparative outcomes of endovascular repair for thoracic and abdominal INAAs.Methods and Results: Patients with naïve thoracic or abdominal INAAs managed with endovascular repair between 2001 and 2018 were included in this multicenter retrospective cohort. The confounding factors were adjusted with propensity score (PS). Of the 39 thoracic and 43 abdominal INAA cases, 41 (50%) presented with aneurysmal rupture, most of which were at the infrarenal abdominal (n=35, 42.7%) or descending thoracic aorta (n=25, 30.5%). Salmonella spp. was the most frequently isolated pathogen. The overall in-hospital mortality rate was 18.3%. The risks of in-hospital death and death due to rupture were significantly lower with thoracic INAAs (12.8% vs. 23.3%; PS-adjusted odds ratio (OR) 0.24, 95% confidence interval (CI) 0.06-0.96; 0.1% vs. 9.3%; PS-adjusted OR 0.11, 95% CI 0.01-0.90). During a mean follow-up of 2.5 years, the risk of all-cause death was significantly higher with thoracic INAAs (35.3% vs. 15.2%; PS-adjusted HR 6.90, 95% CI 1.69-28.19). Chronic kidney disease (CKD) was associated with death. CONCLUSIONS: Compared with thoracic INAAs, endovascular repair of abdominal INAAs was associated with a significantly higher in-hospital mortality rate. However, long-term outcomes were worse for thoracic INAAs, with CKD and infections being the most important predictor and cause of death, respectively.

Cardiovascular and renal outcomes in patients with atrial fibrillation and stage 4-5 chronic kidney disease receiving direct oral anticoagulants: a multicenter retrospective cohort study.

The role of direct oral anticoagulants (DOAC) in patients with atrial fibrillation (AF) and stage 4-5 chronic kidney disease (CKD) is controversial. Electronic medical records from 2012 to 2021 were retrieved for patients with AF and stage 4-5 CKD receiving oral anticoagulants. Patients were separated into those receiving DOACs (dabigatran, rivaroxaban, apixaban, or edoxaban) or vitamin K antagonists (VKA). Primary outcomes included ischemic stroke (IS), systemic thrombosis (SE), major bleeding, gastrointestinal bleeding, hemorrhagic stroke, acute myocardial infarction, cardiovascular death, and all-cause death. Renal outcomes included eGFR declines, creatinine doubling, progression to dialysis, and major adverse kidney events (MAKE). The primary analysis was until the end of follow up and the results at 1-year and 2-year of follow ups were also assessed. 2,382 patients (DOAC = 1,047, VKA = 1,335) between 2012 and 2021 with AF and stage 4-5 CKD were identified. The mean follow-up period was 2.3 ± 2.1 years in DOCAs and 2.6 ± 2.3 years in VKA respectively. At the end of follow up, the DOAC patients had significantly decreased SE (subdistribution hazard ratio [SHR] = 0.50, 95% confidence interval [CI] = 0.34-0.73), composite of IS/SE (SHR = 0.78, 95% CI = 0.62-0.98), major bleeding (HR = 0.77, 95% CI = 0.66-0.90), hemorrhagic stroke (HR = 0.52, 95% CI = 0.36-0.76), and composite of bleeding events (SHR = 0.80, 95% CI = 0.69-0.92) compared with VKA patients. The IS efficacy outcome revealed neutral between DOAC and VKA patients (HR = 1.05, 95% CI = 0.79-1.39). In addition, DOAC patients had significantly decreased rates of eGFR decline > 50% (SHR = 0.75, 95% CI = 0.64-0.87), creatinine doubling (SHR = 0.80, 95% CI = 0.67-0.95), and MAKE (SHR = 0.81, 95% CI = 0.71-0.93). In patients with AF and stage 4-5 CKD, use of DOAC was associated with decreased rates of a composite of ischemic stroke/systemic embolism, a composite of bleeding events, and renal events compared to VKA. Efficacy and safety benefits associated with apixaban at standard doses were consistent throughout follow-up.

Mechanical Versus Bioprosthetic Aortic Valve Replacement in Patients Undergoing Bentall Procedure.

BACKGROUND: The widely used Bentall procedure is the criterion standard treatment for aortic root pathology. Studies comparing the long-term outcomes of bioprosthetic and mechanical valves in patients undergoing the Bentall procedure are limited. METHODS AND RESULTS: Patients who underwent the Bentall procedure with a bioprosthetic or mechanical valve between 2001 and 2018 were identified from Taiwan's National Health Insurance Research Database. The primary outcome of interest was all-cause mortality. Inverse probability of treatment weighting was performed to compare the 2 prosthetic types. In total, 1052 patients who underwent the Bentall procedure were identified. Among these patients, 351 (33.4%) and 701 (66.6%) chose bioprosthetic and mechanical valves, respectively. After inverse probability of treatment weighting, no significant differences in the in-hospital mortality (odds ratio, 0.96 [95% CI, 0.77-1.19]; P=0.716) and all-cause mortality (34.1% vs. 38.1%; hazard ratio, 0.90 [95% CI, 0.78-1.04]; P=0.154) were observed between the groups. The benefits of relative mortality associated with mechanical valves were apparent in younger patients and persisted until ≈50 years of age. CONCLUSIONS: No differences in survival benefits were observed between the valves in patients who underwent the Bentall procedure. Additionally, bioprosthetic valves may be a reasonable choice for patients aged >50 years when receiving the Bentall procedure in this valve-in-valve era.

Factors affecting the intensity of chronic musculoskeletal pain in patients with cardiovascular disease and evaluation of the efficacy of magnesium emulsion cream for muscle cramps.

Chronic musculoskeletal pain (CMP) is associated with an increased risk of cardiovascular disease (CVD). This study aimed to determine the factors associated with the intensity of CMP in patients with underlying CVD and to evaluate the efficacy of Ice Power Magnesium In Strong Cream in patients with muscle cramps. We investigated 396 patients with or without CMP who visited an outpatient cardiology clinic and analyzed the features of CMP and factors associated with pain intensity and specific types of CVD in study 1. We also analyzed 73 patients who had muscle cramps in the lower extremities in study 2 to evaluate the efficacy of Ice Power Magnesium In Strong Cream in reducing pain intensity. In study 1, multivariable linear regression analysis showed that older age (regression coefficient [B] = 0.66, 95% confidence interval [CI], 0.07-1.24), female sex (B = 1.18, 95% CI, 0.59-1.76), presence of hypertension (B = 0.69, 95% CI, 0.05-1.33), and use of calcium supplements (B = 1.27, 95% CI, 0.31-2.24) were significantly associated with a higher intensity of CMP. In study 2, the mean pain scores at baseline, week 2 and week 4 after treatment were 5.99 ± 2.12, 2.92 ± 2.63, and 1.90 ± 2.41, respectively, and the reductions were significant at both week 2 and week 4 after treatment (P < .05). Older age, female sex, hypertension, and use of calcium supplements were associated with an increased intensity of CMP. Ice Power Magnesium In Strong Cream was effective in reducing the pain intensity of muscle cramps in the lower extremities.

Cancer Therapy-Related Cardiac Dysfunction in Patients With Prostate Cancer Undergoing Androgen Deprivation Therapy.

Background The risk of cardiac dysfunction for patients with prostate cancer undergoing androgen deprivation therapy (ADT) in the real-world setting remains unclear. Methods and Results A total of 1120 patients with prostate cancer and a baseline echocardiography scan were identified from Chang Gung Research Database between January 1, 2001 and December 31, 2019. Patients were treated with gonadotropin-releasing hormone agonist therapy, gonadotropin-releasing hormone antagonist therapy, or bilateral orchiectomy. Changes in left ventricular ejection fraction (LVEF) were further assessed in 421 patients using repeated measurements of LVEF before and during ADT treatment. The incidence of cancer therapy-related cardiac dysfunction (CT-RCD) was evaluated and defined as a ≥10% absolute decline in LVEF from baseline to a value of <53%. Among 421 patients undergoing ADT, LVEF declined from 66.3±11.3% to 62.5±13.6% (95% CI of mean difference: -5.0% to -2.7%) after a mean follow-up period of 1.6±0.8 years. CT-RCD occurred in 58 patients (13.7%) with a nadir LVEF of 40.3±9.1% after ADT. Lower baseline LVEF was significantly associated with CT-RCD (odds ratio, 1.07 [95% CI, 1.04-1.10]). The area under the curve of baseline LVEF for discriminating CT-RCD was 75.6%, with the corresponding optimal cutoff value of 64.5% (sensitivity, 79.3%; specificity, 67.2%). Conclusions ADT with gonadotropin-releasing hormone agonist therapy, gonadotropin-releasing hormone antagonist therapy, and bilateral orchiectomy were associated with an increased risk of CT-RCD in patients with prostate cancer. In addition, lower baseline LVEF was a significant predictor of CT-RCD in patients with prostate cancer undergoing treatment with ADT.

Clinical outcomes of generic versus brand-name clopidogrel for secondary prevention in patients with acute myocardial infarction: A nationwide cohort study.

Skepticism exists among healthcare workers and patients regarding the efficacy and safety of generic medication, despite its potential to lower healthcare costs. This study aimed to compare the outcomes of a generic clopidogrel and its brand-name counterpart for secondary prevention in patients with acute myocardial infarction (AMI). Using the Taiwan National Health Insurance Research Database, we identified 49,325 patients who were hospitalized for AMI between January 1, 2008 and December 31, 2013 and prescribed either generic or brand-name clopidogrel. Among them, 2419 (4.9%) were prescribed the generic clopidogrel. After propensity score matching, both the generic and brand-name groups consisted of 2382 patients. The primary efficacy outcome was a composite of myocardial infarction, coronary revascularization, ischemic stroke, and all-cause death. The primary safety outcome was major bleeding requiring hospitalization. At a mean follow-up of 2.5 years, the generic and brand-name clopidogrel groups had comparable risks of primary efficacy outcome (41.9% vs. 42%; hazard ratio [HR] 0.96; 95% confidence interval [CI] 0.88-1.04), and the risks of the individual components were also similar. There were no significant differences between the two groups in major bleeding (7.9% vs. 7.9%; HR 0.99; 95% CI 0.81-1.21). Subgroup analyses also revealed no statistically significant interactions between the treatment effect and various subgroups. In this retrospective database analysis, the generic clopidogrel was comparable to its brand-name counterpart regarding cardiovascular and bleeding outcomes for the treatment of patients with AMI.

Durability of Biological Valves Implanted in Aortic or Mitral Positions: A Nationwide Cohort Study.

BACKGROUND: Biologic prostheses are being increasingly used for aortic and mitral valve replacement (AVR and MVR). This study evaluated the long-term durability of bioprosthetic valves in the mitral and aortic positions, as no well-designed population-based studies have addressed this issue before. METHODS: Using Taiwan's National Health Insurance Research Database, we compared biologic valve durability in the mitral and aortic positions in patients hospitalized between 2001 and 2017, with reoperation as the primary outcome. Both between-subject and within-subject designs were used, and the propensity score matching cohort (1:1 ratio) was created for the former. RESULTS: We identified a total of 10,308 patients, 5462 of whom received AVR, 3901 received MVR, and 945 received double valve replacement. Both AVR and MVR cohorts had 2259 patients after matching. During a mean follow-up of 4.2 years (range, 1 day to 17.9 years), the reoperation rate in the MVR cohort (3.5%) was higher than that in the AVR cohort (2.6%) (hazard ratio 1.41; 95% CI, 1.01-1.98). A higher risk of all-cause death was observed in the MVR cohort (36.5%) than in the AVR cohort (32.6%) (hazard ratio 1.21; 95% CI, 1.10-1.34). Among patients receiving double valve replacement with the same prosthesis type, valves implanted in the aortic position were considerably less likely to require reimplantation. CONCLUSIONS: Bioprosthetic valve placement in the aortic position is associated with superior outcomes in terms of durability, long-term mortality, and perioperative morbidity. Developing novel interventions and enhancing valve durability would expand bioprosthesis use for valve replacement.
