Cardiovascular disease risk assessment and multidisciplinary care in prostate cancer treatment with ADT: recommendations from the APMA PCCV expert network.

PURPOSE: Androgen deprivation therapy (ADT) is the mainstay approach for prostate cancer (PCa) management. However, the most commonly used ADT modality, gonadotropin-releasing hormone (GnRH) agonists, has been associated with an increased risk of cardiovascular disease (CVD). METHODS: The PCa Cardiovascular (PCCV) Expert Network, consisting of multinational urologists, cardiologists and oncologists with expertise in managing PCa, convened to discuss challenges to routine cardiovascular risk assessment in PCa management, as well as how to mitigate such risks in the current treatment landscape. RESULTS: The experts identified several barriers, including lack of awareness, time constraints, challenges in implementing risk assessment tools and difficulties in establishing multidisciplinary teams that include cardiologists. The experts subsequently provided practical recommendations to improve cardio-oncology care for patients with PCa receiving ADT, such as simplifying cardiovascular risk assessment, individualising treatment based on CVD risk categories, establishing multidisciplinary teams and referral networks and fostering active patient engagement. A streamlined cardiovascular risk-stratification tool and a referral/management guide were developed for seamless integration into urologists' practices and presented herein. The PCCV Expert Network agreed that currently available evidence indicates that GnRH antagonists are associated with a lower risk of CVD than that of GnRH agonists and that GnRH antagonists are preferred for patients with PCa and a high CVD risk. CONCLUSION: In summary, this article provides insights and guidance to improve management for patients with PCa undergoing ADT.

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.

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.

Fluoroquinolones and Risk of Aortic Aneurysm or Dissection in Patients With Congenital Aortic Disease and Marfan Syndrome.

BACKGROUND: Fluoroquinolone use can be associated with an increased risk of aortic aneurysm (AA) or aortic dissection (AD). The US Food and Drug Administration recently warned against fluoroquinolone use for high-risk patients, such as those with Marfan syndrome. However, the association between fluoroquinolone use and AA/AD risk was unknown in these high-risk patients and therefore it was studied in this work.Methods and Results: Data were collected from a national database between 2000 and 2017 for 550 patients with AA/AD and any congenital aortic disease (mean age 41.5 years; 415 with Marfan syndrome). A case cross-over study was conducted to compare the risk of aortic events (AA/AD) associated with fluoroquinolone and amoxicillin use between the hazard period (from -60 days to -1 day) and a randomly selected reference period (-180 to -121 days; -240 to -181 days; and -300 to -241 days). Compared to the reference period without fluoroquinolone use, fluoroquinolone use during the hazard period was not associated with a greater risk of AA/AD (1.09% vs. 1.09%; odds ratio [OR] 1.000; 95% confidence interval [CI] 0.32-3.10), AA (OR 0.67; 95% CI 0.11-3.99), or AD (OR 1.33; 95% CI 0.30-5.96) in patients with congenital aortic disease or Marfan syndrome. This lack of association was maintained in subgroup analysis, including Marfan syndrome or not, age (≤50 vs. >50 years) and sex. CONCLUSIONS: Fluoroquinolone use was not associated with an increased risk of AA/AD in patients with congenital aortic disease, including Marfan syndrome. More evidence is required for a fluoroquinolone pharmacovigilance plan in these patients.

Cholinesterase inhibitors associated with lower rate of mortality in dementia patients with heart failure: a nationwide propensity weighting study.

PURPOSE: This study investigates the potential impact of cholinesterase inhibitors (ChEIs) on patients with heart failure (HF) and dementia. ChEIs are known to boost acetylcholine levels and benefit cognition in patients with dementia; however, their effect on patients with HF is uncertain. This study aimed to assess whether cardiovascular events and mortality among patients with HF and dementia are altered by ChEI therapy. METHODS: Data from the National Health Insurance Research Database in Taiwan were retrospectively analyzed. Dementia patients diagnosed with HF were followed for 5 years until all-cause mortality, cardiovascular mortality, hospitalization for worsening HF, or the end of the study. Multivariable Cox models and inverse probability of treatment weighting (IPTW) were employed. RESULTS: Out of 20,848 patients with dementia, 5138 had HF. Among them, 726 were ChEI users and 4412 were non-users. Based on IPTW, the ChEI users had significantly lower estimated risks of all-cause mortality [hazard ratio (HR) 0.43; 95% confidence interval (CI) 0.38-0.49, p < 0.001] and cardiovascular mortality (HR 0.41; 95% CI 0.33-0.53, p < 0.001) compared with the non-users, but there was no significant difference in hospitalization for worsening HF (HR 0.73; 95% CI 0.51-1.05, p = 0.091) after 5 years. The survival benefits of ChEIs were consistent across subgroups. CONCLUSIONS: The results of this retrospective cohort study suggest that ChEIs may be beneficial in reducing all-cause and cardiovascular mortality in patients with dementia with HF. Further research is needed to validate these findings and explore the potential benefits of ChEIs in all patients with HF, including those without dementia.

Gonadotropin-releasing hormone antagonist associated with lower cardiovascular risk compared with gonadotropin-releasing hormone agonist in prostate cancer: A nationwide cohort and in vitro study.

BACKGROUND: We aimed to determine whether cardiovascular (CV) risk in patients with prostate cancer (PCa) differs between those who receive gonadotropin-releasing hormone (GnRH) agonist (GnRHa) therapy and those who receive GnRH antagonist therapy. METHODS: Using the Taiwan National Health Insurance Research Database, we analyzed data by comparing 666 participants receiving GnRH antagonists and 1332 propensity score-matched participants treated with GnRHa in a 1:2 fashion during the period from May 1, 2015, to September 30, 2018. Cox proportional-hazards models were used to estimate the treatment effect on CV outcomes. Furthermore, we conducted an in vitro study to investigate the effect of a GnRHa (leuprolide) or a GnRH antagonist (degarelix) on matrix metalloproteinase-9 (MMP-9) expression and invasion ability in THP-1 differentiated macrophages. RESULTS: GnRH antagonist therapy was associated with a lower risk of composite CV events of myocardial infarction, ischemic stroke, or CV death (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.25-0.90) than GnRHa therapy, with a mean follow-up period of 1.21 years. Significantly lower risks of CV death (HR, 0.21; 95% CI, 0.06-0.70) and all-cause mortality (HR, 0.77; 95% CI, 0.61-0.97) were observed in the GnRH antagonist group. In the in vitro study, leuprolide, but not degarelix, significantly increased the expression of MMP-9 activity and the invasive ability of THP-1 differentiated macrophages through gelatin zymography and the matrix invasion assay, respectively. CONCLUSION: GnRH antagonists were associated with reduced risk CV events compared with the GnRHa among patients with PCa, which may be through effects on macrophages.

LncRNA EWSAT1 Regulates the Tumorigenesis of NSCLC as a ceRNA by Modulating miR-330-5p/ITGA5 Axis.

The aim of the study is to investigate how lncRNA EWSAT1 regulates the tumorigenesis of non-small cell lung cancer (NSCLC) as a ceRNA by modulating miR-330-5p/ITGA5 axis. qRT-PCR was conducted to evaluate the expression of EWSAT1 in NSCLC tissue. Then, A549 cells were selected and divided into Blank shScramble, shEWSAT1, miR-330-5p inhibitor, shEWSAT1 + miR-330-5p inhibitor, and siITGA5 and miR-330-5p inhibitor + siITGA5 groups. Besides, a series of in-vitro experiments were carried out to determine the changes in cell proliferation, apoptosis, invasion, and migration in each group. In addition, xenograft models were also constructed on nude mice to detect the tumor volume and weight, and the expression of Ki67 and apoptosis in xenograft tumor were evaluated. In NSCLC tissue and cell, EWSAT1 was upregulated significantly, demonstrating a correlation with tumor diameter, differentiation, lymph node metastasis, and TNM stage. Dual luciferase reporter gene assay confirmed targeting relationships among miR-330-5p, EWSAT1, and ITGA5. In comparison with the Blank group, the number of cell clones in the shEWSAT1 group and siITGA5 decreased, with declined invasion and migration but increased apoptotic rate. Meanwhile, ITGA5, MMP-2, and MMP-9 were downregulated with upregulated cleaved caspase-3. However, the changes above were totally reversed in the miR-330-5p inhibitor group, and miR-330-5p inhibitor transfection abolished the effect of shEWSAT1. In addition, subcutaneous xenotransplantation showed that the tumor growth in shEWSAT1 group retarded significantly, with downregulation of Ki67 and increase apoptotic rate. Silencing EWSAT1 could inhibit the expression of ITGA5 via upregulating miR-330-5p, thus, resulting in the inhibition of NSCLC cell growth.

Sodium-glucose cotransporter 2 inhibitor versus metformin as first-line therapy in patients with type 2 diabetes mellitus: a multi-institution database study.

BACKGROUND: Sodium-glucose co-transporter 2 inhibitors (SGLT2i) has shown evidence of cardiovascular benefit in patients with type 2 diabetes mellitus (T2DM). Currently metformin is the guideline-recommended first-line treatment. We aimed to investigate the benefit of SGLT2i vs metformin as first-line therapy. METHODS: Electronic medical records from Chang Gung Research Database during 2016-2019 were retrieved for patients with T2DM. Patients aged < 20, not receiving anti-diabetic medication, first-line treatment neither metformin nor SGLT2i were excluded. Primary outcomes were heart failure hospitalization, acute coronary syndrome, ischemic stroke, and all-cause mortality. Patients were followed up for events or December 31, 2019, whichever comes first. RESULTS: After exclusion criteria, a total of 41,020 patients with T2DM were eligible for analysis. There were 1100 patients with SGLT2i as first-line and 39,920 patients with metformin as first-line treatment. IPTW was used for propensity score matching. During one year follow-up, the hazard ratio (HR) of patients on SGLT2i as first-line treatment to patients on metformin as first-line treatment were HR 0.47 (95% CI 0.41-0.54, p < 0.0001) in heart failure hospitalization, HR 0.50 (95% CI 0.41-0.61, p < 0.0001) in acute coronary syndrome, HR 1.21 (95% CI 1.10-1.32, p < 0.0001) in ischemic stroke, and HR 0.49 (95% CI 0.44-0.55, p < 0.0001) in all-cause mortality. CONCLUSIONS: In patients with T2DM, SGLT2i as first-line treatment may be associated with decreased events of heart failure hospitalization, acute coronary syndrome, and all-cause mortality, compared with metformin as first-line treatment. However, there may be an increased events of ischemic stroke using SGLT2i compared to metformin.

Angiographic Complete versus Clinical Selective Incomplete Percutaneous Revascularization in Heart Failure Patients with Multivessel Coronary Disease.

BACKGROUND: Patients with multivessel disease (MVD) often pursue complete revascularization (CR) during percutaneous coronary intervention (PCI) to improve prognosis. However, angiographic CR is not always feasible and is associated with some procedure-related complications in heart failure (HF) patients with MVD. Clinical selective incomplete revascularization (IR) may be reasonable for these high-risk patients, but its role in long-term outcomes remains uncertain. METHODS: Six hundred patients with HF and MVD submitted to PCI were enrolled. Major adverse cardiac events (MACEs) were defined as a composite of recurrent myocardial infarction, any revascularization, and all-cause mortality at 5 years. RESULTS: During a mean follow-up period of 3.7 ± 1.9 years, there was no significant difference in 5-year MACEs between selective IR and successful angiographic CR in HF patients with MVD. However, patients who failed CR had a significantly greater incidence of 5-year MACEs than those in the other two groups (failed CR: 46.4% vs. selective IR: 27.7% vs. successful CR: 27.8%, p < 0.001). CONCLUSIONS: Long-term outcomes of selective IR were comparable with those of successful angiographic CR in HF patients with MVD. However, patients that failed CR showed 2.53-fold increased risk of MACEs compared to patients undergoing either selective IR or successful angiographic CR. A more comprehensive planning strategy should be devised before PCI in HF patients with MVD.

Spontaneous bilateral haemothorax with haemopericardium secondary to rivaroxaban.

WHAT IS KNOWN AND OBJECTIVE: Although the risk of major bleeding with non-vitamin K antagonist oral anticoagulant (NOAC) is low, life-threatening bleeding can occur. CASE SUMMARY: We report a case of an 81-year-old female with deep vein thrombosis who developed bilateral spontaneous haemothorax and haemopericardium after rivaroxaban therapy. Diagnostic thoracentesis revealed a grossly bloody pleural effusion. She was treated with factor eight inhibitor bypassing agent, but the result was not satisfactory. WHAT IS NEW AND CONCLUSION: To our knowledge, this is the first case report of a concomitant presentation of spontaneous bilateral haemothorax and haemopericardium due to rivaroxaban use. This case highlights the potential risk of major haemorrhagic complication of NOAC, which could be life-threatening and require emergent reversal.

Cardiovascular toxicity of immune checkpoint inhibitors in cancer patients: A review when cardiology meets immuno-oncology.

Immune checkpoint inhibitors (ICIs) are a novel treatment option for cancer therapy, which help direct the immune system to recognize and target cancer cells. ICIs have been shown to provide significant mortality benefits for cancer patients, but they are also associated with immune-mediated toxicity. Unlike most immune-related adverse events, which are a common occurrence, reversible and can be treated effectively with glucocorticoid therapy, ICI-associated cardiotoxicities are uncommon, with serious complications and a relatively high mortality even when treated with glucocorticoids. ICI-associated cardiotoxicity can manifest in various ways, including myocarditis, arrhythmias and conduction disease, pericardial disease, myocardial infarction, non-inflammatory cardiomyocyte dysfunction, and even Takotsubo-like cardiomyopathy. The present review summarizes the current understanding of ICI-associated cardiotoxicities, examining the epidemiology and timing of onset, as well as their clinical presentation, diagnostic modalities, pathophysiology, clinical management and outcomes. Although the literature describing ICI-associated cardiotoxicity remains limited to case reports, case series and early clinical trials, strategies for the surveillance, diagnosis and management of this potentially fatal cardiovascular complication of cancer therapy have been proposed.

Comparison of 9-Month Angiographic Follow-Up and Long-Term Clinical Outcomes of Biodegradable Polymer Drug-Eluting Stents and Second-Generation Durable Polymer Drug-Eluting Stents in Patients Undergoing Single Coronary Artery Stenting.

BACKGROUND: The durable polymers (DP) used in first-generation drug-eluting stents (DESs) were associated with long-term cardiovascular events, and thus biodegradable polymer DESs (BP-DESs) and second-generation DP-DESs were designed to overcome this problem. In this study, we compared angiographic follow-up and long-term clinical outcomes between patients who received BP-DESs or second-generation DP-DESs. METHODS: We enrolled 436 patients with single coronary lesions who received a second-generation DP-DES or BP-DES between June 2009 and October 2012. All patients received follow-up angiography when new clinical events developed or at 9 months after index stenting. All participants received follow-up for 5 years. RESULTS: There were no significant differences in patient and lesion characteristics between the two groups. The 9-month angiographic follow-up showed a lower net gain in the second-generation DP-DES group (2.19 mm vs. 2.41 mm, p = 0.040), but a similar binary restenosis rate between the two groups (5.4% vs. 8.7%, p = 0.276). During the 5-year follow-up period, no significant differences were observed between the two groups in major adverse cardiac events (MACEs), cardiovascular death, nonfatal myocardial infarction (MI), target vessel revascularization (TVR), all revascularization, stent thrombosis (ST), or MACE-free survival. CONCLUSIONS: No significant differences were observed in cardiovascular death, nonfatal MI, TVR, all revascularization, ST, or MACE-free survival between the patients undergoing single coronary artery stenting with BP-DESs and second-generation DP-DESs.

Effects of National Hospital Accreditation in Acute Coronary Syndrome on In-Hospital Mortality and Clinical Outcomes.

BACKGROUND: Acute coronary syndrome (ACS) is a life-threatening medical condition that accounts for an annual expenditure of more than $300 billion in the United States. Hospital accreditation has been shown to improve patient and hospital outcomes for various conditions. OBJECTIVES: This study aimed to determine the benefits of hospital accreditation in patients with ACS. METHODS: This nationwide population-based cohort study used Taiwan's National Health Insurance Research Database from 1997 to 2011 (n = 249,354). Multivariable logistic regression was used to analyze the risk of in-hospital events among those treated in accredited and non-accredited hospitals, and to compare outcomes in hospitals before and after accreditation. The effect of accreditation on these events was also stratified by accreditation grade. RESULTS: A total of 823 hospitals were included, of which 2.4% were medical centers, 13.7% were regional hospitals, and 83.8% were district hospitals. The in-hospital mortality [odds ratio (OR), 0.82; 95% confidence interval (CI), 0.79-0.85; p < 0.001] and recurrent acute myocardial infarction (AMI) admission (OR, 0.81; 95% CI, 0.71-0.93; p = 0.003) rates were significantly lower in the after-accreditation group than in the before-accreditation group. There was a substantial and marked decrease in the in-hospital mortality rate after accreditation in 2008. CONCLUSIONS: This cohort study demonstrated that ACS accreditation was associated with better in-hospital mortality and recurrent AMI admission rates in ACS patients.

Complete and incomplete revascularization in non-ST segment myocardial infarction with multivessel disease: long-term outcomes of first- and second-generation drug-eluting stents.

The therapeutic effects of reperfusion strategies with complete revascularization (CR) or incomplete revascularization (IR) in non-ST segment myocardial infarction (NSTEMI) patients with multivessel disease (MVD) are controversial. In such patients, whether utilization of different generations of drug-eluting stents (DES) for IR or CR affect long-term major adverse cardiovascular events (MACE) is unknown. This study included 702 NSTEMI patients with MVD who received first-generation (1G) or second-generation (2G) DES. In multivariable analysis, chronic kidney disease, chronic total, 1G DES and IR were independent predictors of long-term MACE. In patients receiving 1G DES, no significant differences of MACE were observed between the IR and CR groups (39.1% vs. 36.2%, p = 0.854). However, in patients receiving 2G DES, significantly fewer MACE were observed in the CR group than in the IR group (3.7% vs. 10.2%, p = 0.002). Compared with patients receiving 1G DES for IR, those receiving 2G DES for IR and CR exhibited significantly lower risk of MACE (59% and 83% lower, respectively). CR could not provide clinical benefits over IR in NSTEMI patients with MVD receiving 1G DES. However, in patients receiving 2G DES, compared with IR, CR was associated with a lower risk of long-term MACE, which was mainly caused by low rates of non-TLR and any revascularization.

Linagliptin and cardiovascular outcomes in type 2 diabetes after acute coronary syndrome or acute ischemic stroke.

BACKGROUND: The cardiovascular safety and efficacy of linagliptin, a dipeptidyl peptidase-4 inhibitor, in patients with type 2 diabetes mellitus (T2DM) after acute coronary syndrome (ACS) or acute ischemic stroke (AIS) are unclear. The aim of our real-world cohort study was to evaluate the cardiovascular outcomes of linagliptin in patients with T2DM after ACS or AIS. METHODS: An open observational noncrossover retrospective cohort study was conducted between June 1, 2012 and December 31, 2013 utilizing Taiwan National Health Insurance Research Database. A total of 1203 patients with T2DM after ACS or AIS were selected as the study cohort. Cardiovascular safety and efficacy of linagliptin were evaluated by comparing outcomes of 401 subjects receiving linagliptin after ACS or AIS to 802 matched control subjects not receiving any incretin-based therapy after ACS or AIS. The primary composite outcome included cardiovascular death, non-fatal myocardial infarction and non-fatal ischemic stroke. RESULTS: The primary composite outcome after 15-month follow-up was 7% (28 patients) in the linagliptin group compared with 6.1% (49 patients) in the control group [hazard ratio (HR) 1.06; 95% confidence interval (CI) .66-1.68]. The linagliptin group also had similar risks of all-cause mortality, hospitalization for heart failure, percutaneous coronary intervention and coronary artery bypass grafting compared to the control group in terms of the secondary outcomes. CONCLUSIONS: In T2DM patients after ACS or AIS, treatment with linagliptin was not associated with increased risks of cardiovascular death, non-fatal myocardial infarction, or non-fatal ischemic stroke.

Comparison of the Acute and Long-Term Outcomes of Patients With Multivessel Coronary Artery Disease After Angiographic Complete and Incomplete Revascularization With Drug-Eluting Stents.

BACKGROUND: Data regarding the long-term outcomes of a large patient population with multivessel coronary artery disease (MV-CAD) after complete revascularization (CR) and incomplete revascularization (IR) with drug-eluting stent (DES) implantation are controversial. The objective of this study was to evaluate differences between the clinical outcomes of CR and IR in such patients.Methods and Results:A total of 1,502 patients with MV-CAD who received DES between April 2005 and August 2016 were enrolled in this study after propensity score matching. The CR group had 751 patients with 1,368 stents implanted in 1,215 lesions, and the IR group had 751 patients with 1,077 stents implanted in 948 lesions. The CR group had a similar rate of in-hospital major adverse cardiovascular events to the IR group (1.9% vs. 1.6%, P=0.844). Follow-up angiography at 9 months showed no significant difference between the 2 groups for restenosis. The CR group had a higher cardiovascular event-free survival rate than the IR group during a mean follow-up period of 71±62 months (81.8% vs. 72.0%, P<0.001). Kaplan-Meier survival analysis also showed better results in the CR group than in the IR group. CONCLUSIONS: Angiographic CR was associated with more favorable long-term cardiovascular outcomes than angiographic IR in patients with MV-CAD after DES implantation.

Propensity Score Matched Analysis of Mechanical vs. Bioprosthetic Valve Replacement in Patients With Previous Stroke.

BACKGROUND: This study compared the long-term outcomes of prosthetic heart valve replacement with mechanical or bioprosthetic valves in patients with prior stroke.Methods and Results:In total, 1,984 patients with previous stroke who had received valve replacement between 2000 and 2011 were identified using the Taiwan National Health Insurance Research Database. Propensity score matching analysis was used. Ultimately, 547 patients were extracted from each group and were eligible for analysis. On survival analysis, the risks of all-cause mortality and recurrence of stroke were similar. The incidence of major bleeding was greater in the mechanical valve group than in the bioprosthetic valve group (P=0.040), whereas no difference was observed in re-do valve surgery. On subgroup analysis, the bioprosthetic valve was favored for older age (≥60 years) and previous gastrointestinal (GI) bleeding patients. The mechanical valve, however, was favored for younger patients (<60 years). CONCLUSIONS: In patients with previous stroke, bioprosthetic valves had a lower incidence of complications connected to major bleeding than did the mechanical valves. Survival and stroke recurrence rates, however, did not differ between the 2 groups. We recommend bioprosthetic valves for patients >60 years or who have a history of GI bleeding.

Predictors of Long-Term Outcomes After Drug-Eluting Balloon Angioplasty for Bare-Metal Stent Restenosis.

BACKGROUND: Clinical trials have investigated efficacy of drug-eluting balloon (DEB) angioplasty for bare-metal stent (BMS) in-stent restenosis (ISR). Few studies have investigated predictors of long-term outcomes following BMS-ISR treatment with DEB. METHODS: From June 2011 to April 2015, 105 patients with 125 BMS-ISR lesions were enrolled from the Cardiovascular Atherosclerosis and Percutaneous TrAnsluminal INterventions (CAPTAIN) registry. All these lesions were treated with DEB angioplasty as final therapy. The major adverse cardiac events (MACEs) were recurrent clinically driven target lesion revascularisation (TLR), myocardial infarction, and cardiac death after DEB angioplasty. RESULTS: After DEB angioplasty, the angiographic stenosis decreased from 84.8%±12.4% to 22.6%±10.4%. Over a mean follow-up duration of 21.7±13.4months, the rates of TLR at 1-12 months and 12-48 months were 4.8% and 4.2%, respectively. The rates of MACEs at 1-12 months and 12-48 months were 6.7% and 6.1%, respectively. Chronic haemodialysis, calcified lesion, chronic total occlusion lesion before stenting, stent with metal-to-artery ratio >16.5%, and residual stenosis >25% after DEB angioplasty were potential risk factors for MACEs in univariate analysis. After adjustment in multivariate analysis, independent predictors of long-term MACEs were identified as chronic haemodialysis, chronic total occlusion lesion before stenting, and residual stenosis >25% after DEB angioplasty. CONCLUSIONS: The long-term results of DEB angioplasty for BMS-ISR are acceptable in this real-world registry. Patient (chronic haemodialysis), lesion (chronic total occlusion) and angioplasty (residual stenosis percentage) related factors predicted long-term outcomes following BMS-ISR treatment with DEB angioplasty.

Heart Failure and Mortality of Adult Survivors from Acute Myocarditis Requiring Intensive Care Treatment - A Nationwide Cohort Study.

Background The correlation between severity and long-term outcomes of pediatric myocarditis have been reported, however this correlation in adults has rarely been studied. Materials and Methods This nationwide population-based cohort study used data from the National Health Insurance Research Database in Taiwan. Patients aged < 75 and > 18 years admitted to an intensive care unit due to acute myocarditis were enrolled and divided into three groups according to mechanical circulatory support (MCS) after excluding major comorbidities. All-cause mortality, cardiovascular death, and heart failure hospitalization were evaluated from January 1, 2001 to December 31, 2011. Results There were 1145 patients with acute myocarditis (mean age 40.2 years, SD: 14.8 years), of which 851 did not require MCS, 99 underwent intra-aortic balloon pump (IABP) support, and 195 extracorporeal membrane oxygenation (ECMO) support. There was no significant difference in heart failure hospitalization between the three groups after index admission. The incidence of cardiovascular death after discharge ranged from 10 % to 22%, which was highest in the ECMO group, and was also significantly different between the three groups within 3 months (p<0.001) but it disappeared after 3 months (p=0.458). The trend was also noted in incidence of all-cause mortality. Conclusions The severity of acute myocarditis did not affect long-term outcomes, however, it was associated with cardiovascular/all-cause death within 3 months after discharge.

Postoperative Renal Outcomes of On-Pump Beating-Heart versus Cardioplegic Arrest Coronary Artery Bypass Grafting.

BACKGROUND: The aim of this investigation is to compare the postoperative renal outcomes after on-pump beating- heart versus conventional cardioplegic arrest coronary artery bypass grafting (CABG). METHODS: Between January 2010 and December 2012, 254 patients who underwent isolated CABG were enrolled. The primary outcome was postoperative acute kidney injury (AKI) within 7 days [defined by the Kidney Disease Improving Global Outcome (KDIGO) Clinical Practice Guideline] and loss of kidney function at 1 year (defined as > 20% loss in estimated glomerular filtration rate from baseline preoperative creatinine level). RESULTS: There was less AKI found for the on-pump beating-heart CABG (30.2% versus 46.3%; p = 0.010) group; with significant less stage I AKI (17.6% versus 29.5%; p = 0.035); a trend of less stage II AKI (4.4% versus 10.5%; p = 0.088) and no significant difference in stage III AKI (8.2% versus 6.3%; p = 0.587). The on-pump beating-heart group also had less patients who have lost their kidney function at 1 year (24.8% versus 41.2%; p = 0.021). Furthermore, multivariate analysis identified conventional arrest CABG is an independent risk factor for postoperative AKI and loss of kidney function at 1 year. CONCLUSIONS: On-pump beating-heart CABG has superior short-term and mid-term renal outcomes than conventional cardioplegic arrest CABG.
