Risk of Hemorrhagic Stroke among Patients Treated with High-Intensity Statins versus Pitavastatin-Ezetimibe: A Population Based Study.

High-intensity statin (HIS) is recommended for high-risk patients in current guidelines. However, the risk of hemorrhagic stroke (HS) with HIS is a concern for Asians. Pitavastatin carries pharmacological differences compared with other statins. We compared the risk of HS in patients treated with pitavastatin-ezetimibe vs. HIS. We conducted a population-based, propensity score-matched cohort study using data from the Taiwan National Health Insurance Research Database. From January 2013 to December 2018, adults (≥ 18 years) who received pitavastatin 2-4 mg/day plus ezetimibe 10 mg/day (combination group, N = 3,767) and those who received atorvastatin 40 mg/day or rosuvastatin 20 mg/day (HIS group, N = 37,670) were enrolled. The primary endpoint was HS. We also assessed the difference of a composite safety endpoint of hepatitis or myopathy requiring hospitalization and new-onset diabetes mellitus. Multivariable Cox proportional hazards model was used to evaluate the relationship between study endpoints and different treatment. After a mean follow-up of 3.05 ± 1.66 years, less HS occurred in combination group (0.74%) than in HIS group (1.35%) [adjusted hazard ratio (aHR) 0.65, 95% confidence interval (CI) 0.44-0.95]. In subgroup analysis, the lower risk of HS in combination group was consistent among all pre-specified subgroups. There was no significant difference of the composite safety endpoint between the 2 groups (aHR 0.91, 95% CI 0.81-1.02). In conclusion, pitavastatin-ezetimibe combination treatment had less HS compared with high-intensity atorvastatin and rosuvastatin. Pitavastatin-ezetimibe may be a favorable choice for Asians who need strict lipid control but with concern of HS.

Socioeconomic Disparity in the Effect of SARS-CoV-2 on Outpatient Visits among People with Type 2 Diabetes in Taiwan.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak posed impact on healthcare. This study evaluated the effect of SARS-CoV-2 outbreak on the outpatient visits of patients with type 2 diabetes and determined the most affected groups. We analyzed Taiwan's National Health Insurance data, including 1,922,702 patients diagnosed with type 2 diabetes from 2018 to 2021. Group-based trajectory modelling identified four distinct outpatient visit patterns, namely, consistently high (Group 1, 74.2%), low-to-high (Group 2, 8.1%), high-to-low (Group 3, 6.0%) and consistently low (Group 4, 11.7%) utilization. Logistic regression was used to analyze correlations between trajectory types and patients' demographics and health statuses. Group 3 members had higher odds of being male [adjusted odds ratio (aOR) = 1.04, 95% confidence interval (CI) 1.03-1.05] and earning below 20,000 New Taiwan Dollar monthly (aOR = 1.29, 95% CI 1.26-1.31) than those in Group 1. However, they were less likely to be under 80 years old (aOR = 0.70-0.97), from lower median family income regions (aOR = 0.81-0.89) or possess a Charlson Comorbidity Index score > 2 (aOR = 0.67, 95% CI 0.66-0.68). Patients with lower income in affluent areas displayed the highest likelihood of falling into Group 3. Patients with type 2 diabetes and low income from wealthy areas were vulnerable during the pandemic. This result emphasizes the need to target resources and support for this subgroup during such crises.

Recent trends of low-density lipoprotein cholesterol control and lipid-lowering therapy in patients with atherosclerotic cardiovascular disease in Taiwan: 2015-2020.

OBJECTIVE: This study aimd to assess recent trends in the control of low-density lipoprotein cholesterol (LDL-C) and the utilization of lipid-lowering drugs (LLD) among patients with atherosclerotic cardiovascular disease (ASCVD) in Taiwan. METHODS: Patients with ASCVD and without a history of hemorrhagic stroke were identified from the Taiwanese Secondary Prevention for patients with AtheRosCLErotic disease (T-SPARCLE) Registry. ASCVD patients were stratified into four categories: those who ever had acute coronary syndrome (ACS), those who underwent percutaneous coronary intervention or coronary artery bypass grafting (PCI/CABG) without ACS, those who ever had an ischemic stroke (IS) without ACS or PCI/CABG, and other ASCVD cases. We assessed their latest recorded LDL-C levels for the periods 2015-16, 2017-18, and 2019-20. LLD therapy patterns were presented as monotherapy, dual therapy, or combination therapy of three or more drugs, with statin use classified by intensity. RESULTS: We identified 3831 ASCVD patients in 2015-16, 3531 in 2017-18, and 1231 in 2019-20. LLD utilization rose from 58.4% in 2015-16 to 73.2% in 2019-20. The proportions of patients achieving LDL-C goals in 2015-16, 2017-18, and 2019-20 were 21.5%, 25.8%, and 33.3% in the ACS cohort (goal <70 mg/dL); 20.4%, 26.1%, and 39.0% in the PCI/CABG cohort (goal <70 mg/dL); 54.4%, 58.5%, and 58.9% in the IS cohort (goal <100 mg/dL); and 60.0%, 65.5%, and 67.0% in the other ASCVD cohort (goal <100 mg/dL), respectively. Over half of the patients were prescribed moderate-intensity statins. Statin use, age, history of diabetes mellitus, and hypertension were important factors for attaining LDL-C goal in ACS patients. CONCLUSION: Despite improvements in LDL-C management observed over recent years, significant gaps remain in guideline adherence, especially for patients with ACS or PCI/CABG in Taiwan, with over 60% not meeting LDL-C targets. Intensifying efforts to align clinical practice with guidelines are imperative.

2024 Guidelines of the Taiwan Society of Cardiology for the Diagnosis and Treatment of Heart Failure with Preserved Ejection Fraction.

Heart failure with preserved ejection fraction (HFpEF) is a multi-organ systemic syndrome that involves cardiac and extra-cardiac pathophysiological abnormalities. Its growing prevalence causes a major public concern worldwide. HFpEF is usually associated with multiple comorbidities, and non-cardiovascular death is common in patients with HFpEF. In Asia, patients with HFpEF has a younger age, higher prevalence of diabetes and chronic kidney disease than Western countries. A 2-step diagnostic algorithm is recommended in this guideline. In the first step, the diagnosis of HFpEF can be made if patients have symptoms and/or signs of heart failure, left ventricular ejection fraction ≥ 50%, increased natriuretic peptide, and objective evidence of left atrial or left ventricular abnormalities or raised left ventricular filling pressure. If diagnosis is still uncertain, invasive or noninvasive stress test can be performed in the second step. Comorbidities need to be controlled in HFpEF. Weight reduction for obesity and supervised exercise training are recommended for HFpEF. For pharmacological therapy, diuretic is used to relieve congestion and sodium-glucose cotransporter 2 inhibitor, empagliflozin or dapagliflozin, is recommended to improve prognosis of HFpEF. The research on HFpEF is advancing at a rapid pace. It is expected that newer modalities for diagnosis and management of HFpEF could appear in the near future.

Application of genetic risk score for in-stent restenosis of second- and third-generation drug-eluting stents in geriatric patients.

BACKGROUND: The second-and third-generation drug-eluting stents (DESs) in-stent restenosis (ISR) genetic risk score (GRS) model has been previously validated. However, the model has not been validated in geriatric patients. Therefore, we conducted this study to test the feasibility of the DES-ISR GRS model in geriatric patients with coronary artery disease (CAD) in Taiwan. METHODS: We conducted a retrospective, single-center cohort study and included geriatric patients (age ≥ 65 years) with CAD and second-or third-generation DES(s) deployment. Patients undergoing maintenance dialysis were excluded. ISR was defined as ≥ 50% luminal narrowing on the follow-up coronary arteriography. The DES-ISR GRS model included five selected exonic single-nucleotide polymorphisms (SNPs): CAMLG, GALNT2, C11orf84, THOC5, and SAMD11. The GRS was defined as the sum of the five selected SNPs for the risk allele. RESULTS: We enrolled 298 geriatric patients from January 2010 and December 2019 in this study. After propensity score matching, there were 192 geriatric patients with CAD in the final analysis, of which 32 patients had ISR. Patients were divided into two groups based on their GRS values: low (0-2) and high (≥ 3) GRS. A high GRS was significantly associated with DES-ISR in geriatric patients. CONCLUSION: Those geriatric patients with a high GRS had significantly higher second-or third-generation DES ISR rates. The five SNP-derived DES-ISR GRS model could provide genetic information for interventional cardiologists to treat geriatric patients with CAD. TRIAL REGISTRATION: The primary study protocol was registered with clinicaltrials.org. with registration number: NCT03877614; on March 15, 2019. ( http://clinicaltrials.gov/ct2/show/NCT03877614 ).

2023 Guidelines of the Taiwan Society of Cardiology on the Diagnosis and Management of Chronic Coronary Syndrome.

Coronary artery disease (CAD) covers a wide spectrum from persons who are asymptomatic to those presenting with acute coronary syndromes (ACS) and sudden cardiac death. Coronary atherosclerotic disease is a chronic, progressive process that leads to atherosclerotic plaque development and progression within the epicardial coronary arteries. Being a dynamic process, CAD generally presents with a prolonged stable phase, which may then suddenly become unstable and lead to an acute coronary event. Thus, the concept of "stable CAD" may be misleading, as the risk for acute events continues to exist, despite the use of pharmacological therapies and revascularization. Many advances in coronary care have been made, and guidelines from other international societies have been updated. The 2023 guidelines of the Taiwan Society of Cardiology for CAD introduce a new concept that categorizes the disease entity according to its clinical presentation into acute or chronic coronary syndromes (ACS and CCS, respectively). Previously defined as stable CAD, CCS include a heterogeneous population with or without chest pain, with or without prior ACS, and with or without previous coronary revascularization procedures. As cardiologists, we now face the complexity of CAD, which involves not only the epicardial but also the microcirculatory domains of the coronary circulation and the myocardium. New findings about the development and progression of coronary atherosclerosis have changed the clinical landscape. After a nearly 50-year ischemia-centric paradigm of coronary stenosis, growing evidence indicates that coronary atherosclerosis and its features are both diagnostic and therapeutic targets beyond obstructive CAD. Taken together, these factors have shifted the clinicians' focus from the functional evaluation of coronary ischemia to the anatomic burden of disease. Research over the past decades has strengthened the case for prevention and optimal medical therapy as central interventions in patients with CCS. Even though functional capacity has clear prognostic implications, it does not include the evaluation of non-obstructive lesions, plaque burden or additional risk-modifying factors beyond epicardial coronary stenosis-driven ischemia. The recommended first-line diagnostic tests for CCS now include coronary computed tomographic angiography, an increasingly used anatomic imaging modality capable of detecting not only obstructive but also non-obstructive coronary plaques that may be missed with stress testing. This non-invasive anatomical modality improves risk assessment and potentially allows for the appropriate allocation of preventive therapies. Initial invasive strategies cannot improve mortality or the risk of myocardial infarction. Emphasis should be placed on optimizing the control of risk factors through preventive measures, and invasive strategies should be reserved for highly selected patients with refractory symptoms, high ischemic burden, high-risk anatomies, and hemodynamically significant lesions. These guidelines provide current evidence-based diagnosis and treatment recommendations. However, the guidelines are not mandatory, and members of the Task Force fully realize that the treatment of CCS should be individualized to address each patient's circumstances. Ultimately, the decision of healthcare professionals is most important in clinical practice.

2023 TAMIS/TSOC/TACVPR Consensus Statement for Patients with Acute Myocardial Infarction Rehabilitation.

Cardiac rehabilitation is a comprehensive intervention recommended in international and Taiwanese guidelines for patients with acute myocardial infarction. Evidence supports that cardiac rehabilitation improves the health-related quality of life, enhances exercise capacity, reduces readmission rates, and promotes survival in patients with cardiovascular disease. The cardiac rehabilitation team is comprehensive and multidisciplinary. The inpatient, outpatient, and maintenance phases are included in cardiac rehabilitation. All patients admitted with acute myocardial infarction should be referred to the rehabilitation department as soon as clinically feasible. Pre-exercise evaluation, including exercise testing, helps physicians identify the risks of cardiac rehabilitation and organize appropriate exercise prescriptions. Therefore, the Taiwan Myocardial Infarction Society (TAMIS), Taiwan Society of Cardiology (TSOC), and Taiwan Academy of Cardiovascular and Pulmonary Rehabilitation (TACVPR) address this consensus statement to assist healthcare practitioners in performing cardiac rehabilitation in patients with acute myocardial infarction.

2023 Consensus of Taiwan Society of Cardiology on the Pharmacological Treatment of Chronic Heart Failure.

The prevalence of heart failure is increasing, causing a tremendous burden on health care systems around the world. Although mortality rate of heart failure has been significantly reduced by several effective agents in the past 3 decades, yet it remains high in observational studies. More recently, several new classes of drugs emerged with significant efficacy in reducing mortality and hospitalization in chronic heart failure with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF). To integrate these effective therapies and prioritize them in the management of Asian patients, Taiwan Society of Cardiology has recently appointed a working group to formulate a consensus of pharmacological treatment in patients with chronic heart failure. Based on most updated information, this consensus provides rationales for prioritization, rapid sequencing, and in-hospital initiation of both foundational and additional therapies for patients with chronic heart failure.

2022 focused update of the 2017 Taiwan lipid guidelines for high risk patients: Coronary artery disease, peripheral artery disease and ischemic stroke.

The previously published 2017 Taiwan Lipid Guidelines for High Risk Patients becomes the standard guidance of dyslipidemia management for patients with atherosclerotic cardiovascular disease (ASCVD) in Taiwan. New clinical trials of lipid lowering therapy were published successively after 2017. The study results changed the treatment concept of ASCVD. Therefore, an update focusing on the lipid treatment strategy for patients with ASCVD becomes necessary. In this focused update of the 2017 guideline, the treatment targets of low-density lipoprotein cholesterol (LDL-C) for patients with ASCVD were modified. The algorithm of LDL-C lowering therapy was revised. The recommendations in this focused update were made mainly based on the scientific evidence from recently published clinical trials and endorsed by the major medical societies in Taiwan.

2022 Taiwan lipid guidelines for primary prevention.

Elevated circulating low-density lipoprotein cholesterol (LDL-C) is a major risk factor of atherosclerotic cardiovascular disease (ASCVD). Early control of LDL-C to prevent ASCVD later in life is important. The Taiwan Society of Lipids and Atherosclerosis in association with the other seven societies developed this new lipid guideline focusing on subjects without clinically significant ASCVD. In this guideline for primary prevention, the recommended LDL-C target is based on risk stratification. A healthy lifestyle with recommendations for foods, dietary supplements and alcohol drinking are described. The pharmacological therapies for LDL-C reduction are recommended. The aim of this guideline is to decrease the risk of ASCVD through adequate control of dyslipidemia in Taiwan.

Effects of Cilostazol on Angiogenesis in Diabetes through Adiponectin/Adiponectin Receptors/Sirtuin1 Signaling Pathway.

Cilostazol is an antiplatelet agent with vasodilating effects that functions by increasing the intracellular concentration of cyclic adenosine monophosphate. We have previously shown that cilostazol has favorable effects on angiogenesis. However, there is no study to evaluate the effects of cilostazol on adiponectin. We investigated the effects of cilostazol on angiogenesis in diabetes in vitro and in vivo through adiponectin/adiponectin receptors (adipoRs) and the sirtuin 1 (SIRT1)/AMP-activated protein kinase (AMPK) signaling pathway. Human umbilical vein endothelial cells (HUVECs) and human aortic smooth muscle cells (HASMCs) were cocultured under high glucose (HG) conditions. Adiponectin concentrations in the supernatants were significantly increased when HASMCs were treated with cilostazol but not significantly changed when only HUVECs were treated with cilostazol. Cilostazol treatment enhanced the expression of SIRT1 and upregulated the phosphorylation of AMPK in HG-treated HUVECs. By sequential knockdown of adipoRs, SIRT1, and AMPK, our data demonstrated that cilostazol prevented apoptosis and stimulated proliferation, chemotactic motility, and capillary-like tube formation in HG-treated HUVECs through the adipoRs/SIRT1/AMPK signaling pathway. The phosphorylation of downstream signaling molecules, including acetyl-CoA carboxylase (ACC) and endothelial nitric oxide synthase (eNOS), was downregulated when HUVECs were treated with a SIRT1 inhibitor. In streptozotocin-induced diabetic mice, cilostazol treatment could improve blood flow recovery 21-28 days after inducing hindlimb ischemia as well as increase the circulating of CD34+CD45dim cells 14-21 days after operation; moreover, these effects were significantly attenuated by the knockdown of adipoR1 but not adipoR2. The expression of SIRT1 and phosphorylation of AMPK/ACC and Akt/eNOS in ischemic muscles were significantly attenuated by the gene knockdown of adipoRs. Cilostazol improves HG-induced endothelial dysfunction in vascular endothelial cells and enhances angiogenesis in diabetic mice by upregulating the expression of adiponectin/adipoRs and its SIRT1/AMPK downstream signaling pathway.

Management of acute coronary syndrome in patients with suspected or confirmed coronavirus disease 2019: Consensus from Taiwan Society of Cardiology.

Coronavirus disease 2019 (COVID-19) is a highly contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Infection with SARS-CoV may cause coronary plaque instability and lead to acute coronary syndrome (ACS). Management of ACS in patients with COVID-19 needs more consideration of the balance between clinical benefit and transmission risk of virus. This review provides recommendations of management strategies for ACS in patients with suspected or confirmed COVID-19 in Taiwan.

Reduced-Dose Prasugrel versus Clopidogrel for Patients Undergoing Percutaneous Coronary Intervention.

Whether reduced-dose prasugrel has a better efficacy or safety than standard-dose clopidogrel remains unknown in patients undergoing percutaneous coronary intervention (PCI).A systematic search of PubMed, EMBASE, Google Scholar, and Cochrane Library from database inception to May 1, 2020 was performed to compare the clinical outcomes in patients with acute coronary syndrome or stable coronary artery disease undergoing PCI between those treated with reduced-dose prasugrel and clopidogrel. The pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using the fixed-effect or random-effect model if significant heterogeneity was observed. The primary efficacy endpoint was major adverse cardiovascular events (MACE), including cardiovascular (CV) death, myocardial infarction (MI), or ischemic stroke. The primary safety endpoint was all bleeding events.Overall, seven studies with 32,951 patients with PCI were included in the analysis. Reduced-dose prasugrel was associated with a lower risk of MACE than clopidogrel (OR 0.80, 95% CI 0.67-0.97). Except for MI (OR 0.74, 95% CI 0.56-0.98), the secondary efficacy endpoints of CV death, ischemic stroke, all-cause death, and stent thrombosis were similar. For the primary safety endpoint of all bleeding events, there was no significant difference between reduced-dose prasugrel and clopidogrel (OR 1.31, 95% CI 0.87-1.98), but the risk of minor bleeding was significantly higher in reduced-dose prasugrel (OR 1.73, 95% CI 1.25-2.41).In patients undergoing PCI, a lower risk of MACE was found in patients receiving reduced-dose prasugrel than in those with clopidogrel, but a higher risk of minor bleeding events was noted.

Endovascular Therapy for Venous Thromboembolic Diseases.

Thrombolytic therapy plays an important role in treating venous thromboembolic events in patients with unstable hemodynamics or compromised limb circulation. Standard catheter-directed thrombolysis requires a lower dosage of thrombolytic agents than systemic thrombolysis, thus lowering the risk of bleeding. Pharmacomechanical catheter- directed thrombolysis further decreases the dose of thrombolytic agents and duration of infusion. Percutaneous mechanical thrombolysis may potentially become an alternative for patients not suitable for thrombolytic agents. With an increasing number of devices and ongoing trials, endovascular therapy is a promising development that may improve both safety and efficacy in treating venous thromboembolic diseases.

P2Y12 Inhibitor Monotherapy after Percutaneous Coronary Intervention: Is It Safe to Abandon Aspirin?

Dual antiplatelet therapy (DAPT) with aspirin plus a P2Y12 inhibitor for 6-12 months is the current standard treatment for patients after percutaneous coronary intervention (PCI). However, the optimal DAPT duration is still under debate. A novel strategy with P2Y12 inhibitor monotherapy after PCI has been proposed recently. This strategy shortens the duration of DAPT to 1 to 3 months, followed by monotherapy with a P2Y12 inhibitor instead of aspirin. It has been tested in several clinical trials with promising results. In this article, we reviewed the relevant clinical trial data and the scientific rationale of P2Y12 inhibitor monotherapy with laboratory evidence of platelet inhibition. An early aspirin-free strategy with P2Y12 inhibitor monotherapy seems feasible in some of the patients after PCI.

Addressing Vaccine-Induced Immune Thrombotic Thrombocytopenia (VITT) Following COVID-19 Vaccination: A Mini-Review of Practical Strategies.

In response to the COVID-19 pandemic, several vaccines were developed and rolled out at unprecedented speed, and notwithstanding this rapid pace of development, the results from initial clinical trials involving tens of thousands of adult subjects generally indicated that most vaccines were remarkably effective and safe, with no major safety warnings noted. However, with more than 2 billion vaccination doses administered to date, reports of rare adverse events following immunization (AEFI) are beginning to emerge. In late February 2021, atypical thrombotic events following immunization with the adenoviral vector-based ChAdOx1 nCov-19 vaccine were first reported, and similar events have also been observed in recipients of the adenoviral vector-based Ad26.COV2.S vaccine and the mRNA-based BNT162b2 and mRNA-1273 vaccines. These manifestations of atypical thrombosis and thrombocytopenia following COVID-19 vaccine immunization are now collectively referred to as vaccine-induced immune thrombotic thrombocytopenia (VITT). Although the reported incidence remains very low and does not affect the overall benefit of immunization, it is also true that if left untreated, VITT can be debilitating or even fatal. Therefore, this review seeks to provide a comprehensive overview regarding the incidence, pathogenesis, presentation, diagnosis, and treatment of VITT, as well as considerations for special populations, based on the currently available evidence in the literature. It is hoped that this will enhance awareness of this vaccine side effect, so that cases of VITT may be identified and treated in a timely and appropriate manner.

Antithrombotic Treatment of Stable Coronary Artery Disease.

Coronary artery disease (CAD) is one of the leading causes of death in Taiwan. Despite the use of current guideline-recommended therapies for secondary prevention, the residual risk of recurrent cardiovascular events remains high in CAD, warranting the need for new treatment options. Antithrombotic drugs are one of the most important medical therapies for CAD. In this article, we review the unmet needs of the current antithrombotic agents and summarize the results of clinical trials with dual antiplatelet therapy in stable CAD. We also review data from a recent study demonstrating the benefits of a dual pathway inhibition strategy with antiplatelet and anticoagulant therapy, a new option for CAD treatment. Finally, we propose a treatment algorithm for choosing different antithrombotic regimens for CAD based on current scientific evidence and expert opinions.

Changing Treatment Patterns in Patients With Venous Thromboembolism in Taiwan.

BACKGROUND: In Asia, little information is available about contemporary real-world treatment patterns for venous thromboembolism (VTE).Methods and Results:Consecutive patients (n=11,414) from the Taiwan National Health Insurance Research Database with initial VTE and taking oral anticoagulants between May 1, 2014 and June 30, 2016 were included. The temporal trends of using oral anticoagulants and pharmacomechanical therapy during the study period were evaluated. The efficacy and safety of nonvitamin K antagonist oral anticoagulants (NOACs) vs. warfarin were compared. Propensity score analysis (NOACs n=3,647 vs. warfarin n=3,647) was used to balance covariates between groups, and Cox proportional hazards models with adjustment were used to estimate the risks of clinical outcomes. The use of NOACs increased from 0.3% to 60.2% for VTE treatment during the study period. Pharmacomechanical therapy was used in 9.60%, 8.22%, and 5.63% from 2014 through 2016. NOACs were associated with a 16% risk reduction (adjusted hazard ratio [aHR] 0.84, 95% confidence interval [CI] 0.77-0.93) in all-cause mortality and a 21% risk reduction (aHR 0.79, 95% CI 0.65-0.96) in recurrent VTE vs. warfarin. Overall, NOACs were associated with a lower risk of major bleeding compared with warfarin (aHR 0.804, 95% CI 0.648-0.998). CONCLUSIONS: In real-world practice, NOACs have become the major anticoagulant used for Asians with VTE. Although NOACs had a lower risk of recurrent VTE and major bleeding compared with warfarin in Taiwan, we still need a large-scale randomized controlled trial to confirm the findings.

The Asia-Pacific Society of Cardiology (APSC) Expert Committee Consensus Recommendations for Assessment of Suspected Acute Coronary Syndrome Using High-Sensitivity Cardiac Troponin T in the Emergency Department.

The Asia-Pacific Society of Cardiology (APSC) high-sensitivity troponin T (hs-TnT) consensus recommendations and rapid algorithm were developed to provide guidance for healthcare professionals in the Asia-Pacific region on assessing patients with suspected acute coronary syndrome (ACS) using a hs-TnT assay. Experts from Asia-Pacific convened in 2 meetings to develop evidence-based consensus recommendations and an algorithm for appropriate use of the hs-TnT assay. The Expert Committee defined a cardiac troponin assay as a high-sensitivity assay if the total imprecision is ≤10% at the 99th percentile of the upper reference limit and measurable concentrations below the 99th percentile are attainable with an assay at a concentration value above the assay's limit of detection for at least 50% of healthy individuals. Recommendations for single-measurement rule-out/rule-in cutoff values, as well as for serial measurements, were also developed. The Expert Committee also adopted similar hs-TnT cutoff values for men and women, recommended serial hs-TnT measurements for special populations, and provided guidance on the use of point-of-care troponin T devices in individuals suspected of ACS. These recommendations should be used in conjunction with all available clinical evidence when making the diagnosis of ACS.

A performance guide for major risk factors control in patients with atherosclerotic cardiovascular disease in Taiwan.

Atherosclerotic cardiovascular disease (ASCVD), including coronary artery disease, cerebrovascular disease, and peripheral artery disease, carries a high morbidity and mortality. Risk factor control is especially important for patients with ASCVD to reduce recurrent cardiovascular events. Clinical guidelines have been developed by the Taiwan Society of Cardiology, Taiwan Society of Lipids and Atherosclerosis, and Diabetes Association of Republic of China (Taiwan) to assist health care professionals in Taiwan about the control of hypertension, hypercholesterolemia and diabetes mellitus. This article is to highlight the recommendations about blood pressure, cholesterol, and sugar control for ASCVD. Some medications that are beneficial for ASCVD were also reviewed. We hope the clinical outcomes of ASCVD can be improved in Taiwan through the implementation of these recommendations.
