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.

Effects of lorcaserin on cardiometabolic risk factors in overweight and obese patients: A systematic review and meta-analysis.

WHAT IS KNOWN AND OBJECTIVE: Lorcaserin is a selective serotonin 2c receptor agonist approved as an anti-obesity agent. The additional cardiometabolic benefits associated with lorcaserin have not been conclusively established. The aim of the systematic review and meta-analysis is to examine the effects of lorcaserin on blood pressure, heart rate and other metabolic parameters in overweight and obese patients from randomized controlled clinical trials (RCTs). METHODS: A literature search was conducted on PubMed, EMBASE and Cochrane Central using the search terms 'lorcaserin' and 'randomized controlled trials' without language restrictions. RCTs with a follow-up period of at least 24 weeks were included in the meta-analysis. RESULTS AND DISCUSSION: Six studies with 9452 patients in the lorcaserin group and 9392 patients in the placebo group were included. Compared with placebo, lorcaserin not only reduced weight, BMI and waist circumference but also improved SBP, DBP, heart rate, LDL, triglycerides, fasting plasma glucose and HbA1c. Our findings suggest that lorcaserin has trivial though consistent and favourable effects on blood pressure, heart rate and metabolic syndrome. WHAT IS NEW AND CONCLUSION: Lorcaserin improved all cardiometabolic parameters modestly in addition to its weight loss effect in overweight and obese patients. More research is needed to determine its long-term cardiovascular benefits.

Modulation effects of black-vinegar-based supplement against a high-fat dietary habit: antiobesity/hypolipidemic, antioxidative, and energy-metabolism effects.

BACKGROUND: An imbalanced fat or excess energy intake always results in obesity and increased serum/liver lipids, thus leading to metabolic syndromes. Given the bioactive components in black vinegar (BV), such as branched amino acids, phenolic profile, and mineral contents, we investigated the antiobesity effects of BV-based supplements in rats fed a high-fat diet (HFD). RESULTS: HFD (30% fat, w/w) feeding increased (P < 0.05) body weight, weight gains, weights of livers and mesenteric, epididymal, and perirenal adipose tissues, and serum/liver triglyceride levels relative to those of rats fed a normal diet (4% fat, w/w; CON). These increased values were ameliorated (P < 0.05) by supplementing with BV-based supplements but were still higher (P < 0.05) than those of CON rats. The increased areas of perirenal adipocytes in rats fed with an HFD were also decreased (P < 0.05) by supplementing with BV-based supplements, which might result from an upregulation (P < 0.05) of 5'-adenosine monophosphate-activated protein kinase (AMPK), carnitine palmitoyltransferase-1 (CPT1), and uncoupling protein-2 (UCP2) in the perirenal adipose tissues. A similar effect was observed for AMPK, peroxisome proliferator-activated receptor alpha, retinoid X receptor alpha, CPT1, and UCP2 gene and protein levels in livers (P < 0.05). Generally, BV-based supplements increased the fecal triglyceride, cholesterol, and bile acid levels of rats fed with an HFD, which partially contribute to the lipid-lowering effects. Furthermore, BV-based supplements increased (P < 0.05) hepatic Trolox equivalent antioxidant capacity and lowered (P < 0.05) serum/liver thiobarbituric acid reactive substances values in HFD-fed rats. CONCLUSION: In a chronic high-fat dietary habit, the food-grade BV-based supplement is a good daily choice to ameliorate obesity and its associated comorbidities. © 2020 Society of Chemical Industry.

Patient satisfaction with dabigatrean and warfarin for stroke prevention in atrial fibrillation: Taiwan PASSION study.

BACKGROUND: Patient satisfaction with oral anticoagulant (OAC) therapy is an important metric of care quality and has been associated with higher medication persistence. Among OACs, dabigatran has been shown to be non-inferior to vitamin K antagonists (VKAs) with increased ease of use for stroke prevention in patients with atrial fibrillation (AF). In this study, we sought to evaluate the expectations, convenience, and satisfaction of Taiwanese AF patients on dabigatran and VKA therapies as well as associated clinical outcomes. METHODS: Patients with AF (paroxysmal, persistent, or permanent) receiving OAC medication from outpatient facilities were enrolled in 24 hospitals across Taiwan. Cohort A consisted of 139 patients switched from VKA to dabigatran, while cohort B was comprised of 1113 patients on newly initiated OAC therapy (VKA, 54). The Perception of Anticoagulant Treatment Questionnaire was distributed, and responses on a five-point Likert scale were aggregated and analyzed across demographic groups. RESULTS: In cohort A, convenience and satisfaction scores continued to increase at follow-up and significantly higher, compared to baseline, but both treatments scored similarly in cohort B. In cohort B, the two highest expectation scores were that the OAC would be "easy to take" and could be "taken independently." On the other hand, the patients were relatively less concerned about the side effects and cost of therapy before taking the OAC. For dabigatran-receiving patients, there were 1.1 stroke-related events per 100 patient-years and 3.0 bleeding-related events per 100 patient-years. CONCLUSION: In Taiwanese patients with AF and initially treated with VKA, switched to dabigatran resulted in higher convenience and treatment satisfaction. For those patients on newly initiated OAC treatment, VKA and dabigatran convenience and satisfaction scores were similar.

2021 Consensus Pathway of the Taiwan Society of Cardiology on Novel Therapy for Type 2 Diabetes.

Type 2 diabetes is a major threat to human health in the 21st century. More than half a billion people may suffer from this pandemic disease in 2030, leading to a huge burden of cardiovascular complications. Recently, 2 novel antidiabetic agents, glucagon-like peptide 1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, reduced cardiovascular complications in a number of randomized control trials. To integrate new information and to achieve a streamlined process for better patient care, a working group was appointed by the Taiwan Society of Cardiology to formulate a stepwise consensus pathway for these therapies to reduce cardiovascular events in patients with type 2 diabetes. This consensus pathway is complementary to clinical guidelines, acting as a reference to improve patient care.

2020 Consensus of Taiwan Society of Cardiology on the pharmacological management of patients with type 2 diabetes and cardiovascular diseases.

The global incidence and prevalence of type 2 diabetes have been escalating in recent decades. The total diabetic population is expected to increase from 415 million in 2015 to 642 million by 2040. Patients with type 2 diabetes have an increased risk of atherosclerotic cardiovascular disease (ASCVD). About two-thirds of patients with type 2 diabetes died of ASCVD. The association between hyperglycemia and elevated cardiovascular (CV) risk has been demonstrated in multiple cohort studies. However, clinical trials of intensive glucose reduction by conventional antidiabetic agents did not significantly reduce macrovascular outcomes.In December 2008, U.S. Food and Drug Administration issued a mandate that every new antidiabetic agent requires rigorous assessments of its CV safety. Thereafter, more than 200,000 patients have been enrolled in a number of randomized controlled trials (RCTs). These trials were initially designed to prove noninferiority. It turned out that some of these trials demonstrated superiority of some new antidiabetic agents versus placebo in reducing CV endpoints, including macrovascular events, renal events, and heart failure. These results are important in clinical practice and also provide an opportunity for academic society to formulate treatment guidelines or consensus to provide specific recommendations for glucose control in various CV diseases.In 2018, the Taiwan Society of Cardiology (TSOC) and the Diabetes Association of Republic of China (DAROC) published the first joint consensus on the "Pharmacological Management of Patients with Type 2 Diabetes and Cardiovascular Diseases." In 2020, TSOC appointed a new consensus group to revise the previous version. The updated 2020 consensus was comprised of 5 major parts: (1) treatment of diabetes in patients with multiple risk factors, (2) treatment of diabetes in patients with coronary heart disease, (3) treatment of diabetes in patients with stage 3 chronic kidney disease, (4) treatment of diabetes in patients with a history of stroke, and (5) treatment of diabetes in patients with heart failure. The members of the consensus group thoroughly reviewed all the evidence, mainly RCTs, and also included meta-analyses and real-world evidence. The treatment targets of HbA1c were finalized. The antidiabetic agents were ranked according to their clinical evidence. The consensus is not mandatory. The final decision may need to be individualized and based on clinicians' discretion.

A subanalysis of Taiwanese patients from ODYSSEY South Korea and Taiwan study evaluating the efficacy and safety of alirocumab.

BACKGROUND: Alirocumab can provide significant reductions in low-density lipoprotein cholesterol (LDL-C). However, data regarding its efficacy and safety in Asians are limited. METHODS: A subgroup analysis of Taiwanese patients (n = 116) in a randomized trial evaluating the efficacy and safety of alirocumab in South Korea and Taiwan (ODYSSEY KT, clinicaltrials.gov Identifier: NCT02289963) was performed. Patients with hypercholesterolemia at high cardiovascular risk on maximally tolerated statin were randomized to alirocumab (75 mg every 2 weeks; with dose increased to 150 mg at Week 12 if LDL-C ≥ 70 mg/dL at Week 8) or placebo for 24 weeks. The primary efficacy endpoint was the percent change in LDL-C from baseline to Week 24. Safety was assessed for a total of 32 weeks. RESULTS: At Week 24, the percent change in calculated LDL-C in the alirocumab group (n = 57) was -51%, whereas that in the placebo group (n = 59) was 2.5%. Alirocumab significantly improved other lipid parameters, including non-high-density lipoprotein cholesterol, apolipoprotein B and A1, lipoprotein (a), high-density lipoprotein cholesterol, and total cholesterol. A significantly higher proportion of patients in the alirocumab group reached an LDL-C target below 70 mg/dL than those in the placebo group (81.3% vs 15.4%). The incidence of treatment-emergent adverse events was comparable between both groups. CONCLUSION: Alirocumab treatment provided a favorable effect on LDL-C levels and other lipid parameters, and was generally well-tolerated in patients from Taiwan. The results of current analysis were consistent with the overall ODYSSEY phase 3 program.

A randomized trial evaluating the efficacy and safety of alirocumab in South Korea and Taiwan (ODYSSEY KT).

BACKGROUND: Alirocumab, a fully human monoclonal antibody to proprotein convertase subtilisin/kexin type 9, has been shown to provide significant reductions in low-density lipoprotein cholesterol (LDL-C). Data about its efficacy and safety in patients from South Korea and Taiwan are limited. OBJECTIVE: ODYSSEY KT assessed the efficacy and safety of alirocumab in patients from South Korea and Taiwan. METHODS: Patients with hypercholesterolemia at high cardiovascular risk who were on maximally tolerated statin were randomized (1:1) to alirocumab (75 mg every 2 weeks, with dose increase to 150 mg every 2 weeks at week 12 if LDL-C ≥70 mg/dL at week 8) or placebo for 24 weeks. The primary efficacy endpoint was percentage change in LDL-C from baseline to week 24. Safety was assessed throughout. RESULTS: At week 24, alirocumab changed LDL-C levels by -57.1% (placebo: +6.3%). In the alirocumab group, 9 patients (9.5%) received dose increase at week 12. At week 24, 85.8% of patients in the alirocumab group reached LDL-C <70 mg/dL (placebo: 14.2%; P ≤ .0001 vs placebo). Alirocumab significantly improved non-high-density lipoprotein cholesterol (non-HDL-C), apolipoprotein B, total cholesterol, lipoprotein (a), and HDL-C vs placebo (P ≤ .05). Two consecutive calculated LDL-C values <25 mg/dL were recorded in 27.8% of alirocumab-treated patients. Overall, 58.8% (alirocumab) and 61.8% (placebo) of patients experienced treatment-emergent adverse events; 2.1% and 1.0% discontinued treatment due to treatment-emergent adverse events, respectively. CONCLUSION: Alirocumab significantly improved LDL-C, apolipoprotein B, non-HDL-C, lipoprotein (a), HDL-C, and total cholesterol in Asian patients. Alirocumab was generally well tolerated. These findings are consistent with ODYSSEY findings to date.
