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.
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.
Psoriatic disease is a chronic inflammatory disorder with skin and joint manifestations. Due to the persistent inflammatory state exhibited by patients with psoriasis, multiple systemic comorbidities occur more frequently in patients with psoriasis than in the general population, and the risk of cardiovascular (CV) diseases is significantly increased. As the pathophysiology of psoriatic disease is becoming better understood, the sharing of underlying pathogenic mechanisms between psoriatic and CV diseases is becoming increasingly apparent. Consequently, careful attention to CV comorbidities that already exist or may potentially develop is needed in the management of patients with psoriasis, particularly in the screening and primary prevention of CV disease and in treatment selection due to potential drug-drug and drug-disease interactions. Furthermore, as the use of effective biologic therapy and more aggressive oral systemic treatment for psoriatic disease is increasing, consideration of the potential positive and negative effects of oral and biologic treatment on CV disease is warranted. To improve outcomes and quality of care for patients with psoriasis, the Taiwanese Dermatological Association, the Taiwanese Association for Psoriasis and Skin Immunology, and the Taiwan Society of Cardiology established a Task Force of 20 clinicians from the fields of dermatology, cardiology, and rheumatology to jointly develop consensus expert recommendations for the management of patients with psoriatic disease with attention to CV comorbidities.

Fibrosis is a hallmark of atrial structural remodeling. The main aim of this study was to investigate the role of micro-ribonucleic acids (miRNAs) in the modulation of fibrotic molecular mechanisms in response to hypoxic conditions, which may mediate atrial fibrosis. Under a condition of hypoxia induced by a hypoxia chamber, miRNA arrays were used to identify the specific miRNAs associated with the modulation of fibrotic genes. Luciferase assay, real-time polymerase chain reaction, immunofluorescence and Western blotting were used to investigate the effects of miRNAs on the expressions of the fibrotic markers collagen I and III (COL1A, COL3A) and phosphorylation levels of the stress kinase c-Jun N-terminal kinase (JNK) pathway in a cultured HL-1 atrial cardiomyocytes cell line. COL1A and COL3A were found to be the direct regulatory targets of miR-let-7a, miR-let-7e and miR-133a in hypoxic atrial cardiac cells in vitro. The expressions of COL1A and COL3A were influenced by treatment with miRNA mimic and antagomir while hypoxia-induced collagen expression was inhibited by the delivery of miR-133a, miR-let-7a or miR-let-7e. The JNK pathway was critical in the pathogenesis of atrial fibrosis. The JNK inhibitor SP600125 increased miRNA expressions and repressed the fibrotic markers COL1A and COL3A. In conclusion, MiRNA let-7a, miR-let-7e and miR-133a play important roles in hypoxia-related atrial fibrosis by inhibiting collagen expression and post-transcriptional repression by the JNK pathway. These novel findings may lead to the development of new therapeutic strategies.

Hypertension is the most important modifiable cause of cardiovascular (CV) disease and all-cause mortality worldwide. Despite the positive correlations between blood pressure (BP) levels and later CV events since BP levels as low as 100/60 mmHg have been reported in numerous epidemiological studies, the diagnostic criteria of hypertension and BP thresholds and targets of antihypertensive therapy have largely remained at the level of 140/90 mmHg in the past 30 years. The publication of both the SPRINT and STEP trials (comprising > 8,500 Caucasian/African and Chinese participants, respectively) provided evidence to shake this 140/90 mmHg dogma. Another dogma regarding hypertension management is the dependence on office (or clinic) BP measurements. Although standardized office BP measurements have been widely recommended and adopted in large-scale CV outcome trials, the practice of office BP measurements has never been ideal in real-world practice. Home BP monitoring (HBPM) is easy to perform, more likely to be free of environmental and/or emotional stress, feasible to document long-term BP variations, of good reproducibility and reliability, and more correlated with hypertension-mediated organ damage (HMOD) and CV events, compared to routine office BP measurements. In the 2022 Taiwan Hypertension Guidelines of the Taiwan Society of Cardiology (TSOC) and the Taiwan Hypertension Society (THS), we break these two dogmas by recommending the definition of hypertension as ≥ 130/80 mmHg and a universal BP target of < 130/80 mmHg, based on standardized HBPM obtained according to the 722 protocol. The 722 protocol refers to duplicate BP readings taken per occasion ("2"), twice daily ("2"), over seven consecutive days ("7"). To facilitate implementation of the guidelines, a series of flowcharts encompassing assessment, adjustment, and HBPM-guided hypertension management are provided. Other key messages include that: 1) lifestyle modification, summarized as the mnemonic S-ABCDE, should be applied to people with elevated BP and hypertensive patients to reduce life-time BP burden; 2) all 5 major antihypertensive drugs (angiotensin-converting enzyme inhibitors [A], angiotensin receptor blockers [A], ß-blockers [B], calcium-channel blockers [C], and thiazide diuretics [D]) are recommended as first-line antihypertensive drugs; 3) initial combination therapy, preferably in a single-pill combination, is recommended for patients with BP ≥ 20/10 mmHg above targets; 4) a target hierarchy (HBPM-HMOD- ambulatory BP monitoring [ABPM]) should be considered to optimize hypertension management, which indicates reaching the HBPM target first and then keeping HMOD stable or regressed, otherwise ABPM can be arranged to guide treatment adjustment; and 5) renal denervation can be considered as an alternative BP-lowering strategy after careful clinical and imaging evaluation.
Oxygen pulse (O2P) is a function of stroke volume and cellular oxygen extraction and O2P curve pattern (O2PCP) can provide continuous measurements of O2P. However, measurements of these two components are difficult during incremental maximum exercise. As cardiac function is evaluated using ejection fraction (EF) according to the guidelines and EF can be obtained using first-pass radionuclide ventriculography, the aim of this study was to investigate associations of O2P%predicted and O2PCP with EF in patients with heart failure with reduced or mildly reduced ejection fraction (HFrEF/HFmrEF) and chronic obstructive pulmonary disease (COPD), and also in normal controls. This was a prospective observational cross-sectional study. Correlations of resting left ventricular EF, dynamic right and left ventricular EFs and outcomes with O2P% and O2PCP across the three participant groups were analyzed. A total of 237 male subjects were screened and 90 were enrolled (27 with HFrEF/HFmrEF, 30 with COPD and 33 normal controls). O2P% and the proportions of the three types of O2PCP were similar across the three groups. O2P% reflected dynamic right and left ventricular EFs in the control and HFrEF/HFmrEF groups, but did not reflect resting left ventricular EF in all participants. O2PCP did not reflect resting or dynamic ventricular EFs in any of the subjects. A decrease in O2PCP was significantly related to nonfatal cardiac events in the HFrEF/HFmrEF group (log rank test, p = 0.01), whereas O2P% and O2PCP did not predict severe acute exacerbations of COPD. The findings of this study may clarify the utility of O2P and O2PCP, and may contribute to the currently used interpretation algorithm and the strategy for managing patients, especially those with HFrEF/HFmrEF. (Trial registration number NCT05189301.).
AIMS: Use of antiarrhythmic drugs (AADs) in patients with chronic kidney disease (CKD) is challenging owing to issues with renal clearance, drug accumulation, and increased proarrhythmic risks. Because CKD is a common comorbidity in patients with atrial fibrillation/atrial flutter (AF/AFL), it is important to establish the efficacy and safety of AAD treatment in patients with CKD. METHODS AND RESULTS: Dronedarone efficacy and safety in individuals with AF/AFL and varying renal functionality [estimated glomerular filtration rate (eGFR): ≥60, ≥45 and <60, and <45 mL/min] was investigated in a post hoc analysis of ATHENA (NCT00174785), a randomized, double-blind trial of dronedarone vs. placebo in patients with paroxysmal or persistent AF/AFL plus additional cardiovascular (CV) risk factors. Log-rank testing and Cox regression were used to compare the incidence of endpoints between treatments. Overall, 4588 participants were enrolled from the trial. There was no interaction between treatment group and baseline eGFR assessed as a continuous variable (P = 0.743) for the first CV hospitalization or death from any cause (primary outcome). This outcome was lower with dronedarone vs. placebo across a wide range of renal function. First CV hospitalization and first AF/AFL recurrence were both lower in the two least renally impaired subgroups with dronedarone vs. placebo. Treatment emergent adverse events leading to treatment discontinuation were more frequent with dronedarone vs. placebo and occurred more often in patients with severe renal impairment. CONCLUSION: Dronedarone is an effective AAD in patients with AF/AFL and CV risk factors across a wide range of renal function.

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.
A febrile state may provoke a Brugada electrocardiogram (ECG) pattern and trigger ventricular tachyarrhythmias in susceptible individuals. However, the prognostic value of fever-induced Brugada ECG pattern remains unclear. We analyzed the clinical and extended long-term follow-up data of consecutive febrile patients with a type 1 Brugada ECG presented to the emergency department. A total of 21 individuals (18 males; mean age, 43.7 ± 18.6 years at diagnosis) were divided into symptomatic (resuscitated cardiac arrest in one, syncope in two) and asymptomatic (18, 86%) groups. Sustained polymorphic ventricular tachycardias were inducible in two patients with previous syncope. All 18 asymptomatic patients had no spontaneous type 1 Brugada ECG recorded at second intercostal space and no family history of sudden death. Among asymptomatic individuals, 4 had a total 12 of repeated non-arrhythmogenic febrile episodes all with recurrent type 1 Brugada ECGs, and none had a ventricular arrhythmic event during 116 ± 19 months of follow-up. In the symptomatic group, two had defibrillator shocks for a new arrhythmic event at 31- and 49 months follow-up, respectively, and one without defibrillator therapy died suddenly at 8 months follow-up. A previous history of aborted sudden death or syncope was significantly associated with adverse outcomes in symptomatic compared with asymptomatic individuals (log-rank p < 0.0001). In conclusion, clinical presentation or history of syncope is the most important parameter in the risk stratification of febrile patients with type 1 Brugada ECG. Asymptomatic individuals with a negative family history of sudden death and without spontaneous type 1 Brugada ECG, have an exceptionally low future risk of arrhythmic events. Careful follow-up with timely and aggressive control of fever is an appropriate management option.
The study evaluated the changes in polycyclic aromatic hydrocarbons (PAHs) of Oolong tea samples at each heat treatment stage of the manufacturing process, different post-treatment methods and different brewing conditions. The content of PAHs in the tea leaves was significantly increased during stir fixation (280 °C for 8 min) stage of the manufacturing process. In the subsequent heat treatment process, the PAHs content did not change much until the Oolong tea product (primary) was further roasted. The level of PAHs increased with the roasting time. Charcoal roasting resulted in higher PAHs content in the product compared with electric roasting. Higher brewing temperature caused higher level of PAHs released into the tea infusion. The level of released PAHs decreased with the increase of the number of tea brewing (the total released PAHs was about 4%). The risk assessment results for PAHs in the tea infusions showed a low level of health concern.

By promoting atrial structural remodeling, atrial hypoxia contributes to the development of the atrial fibrillation substrate. Our study aimed to investigate the modulatory effect of hypoxia on profibrotic activity in cultured HL-1 cardiomyocytes and explore the possible signaling transduction mechanisms of profibrotic activity in vitro. Hypoxia (1% O2) significantly and time-dependently increased the expression of hypoxia-inducible factor (HIF)-1α and fibrotic marker proteins collagen I and III (COL1A and COL3A), transforming growth factor (TGF)-ß1 and α-smooth muscle actin (SMA). Western blot or immunohistochemistry analysis showed that hypoxia-induced increase in COL1A and COL3A was significantly attenuated by the addition of SP600125 (a specific c-Jun N-terminal kinase [JNK] inhibitor) or expression of dominant-negative JNK before hypoxia treatment. The inhibition of hypoxia-activated phosphorylation of JNK signal components (JNK, MKK4, nuclear c-Jun and ATF-2) by pre-treatment with SP600125 could suppress hypoxia-stimulated HIF-1α upregulation and fibrotic marker proteins expression. Hypoxia significantly increased reactive oxygen species (ROS) production in cultured HL-1 atrial cells. Pre-treatment with N-acetylcysteine significantly abrogated the expression of nuclear HIF-1α, JNK transduction components and fibrotic marker proteins. Taken together, these findings indicated that the hypoxia-induced atrial profibrotic response occurs mainly via the ROS/JNK pathway, its downstream upregulation of HIF-1α and c-Jun/ATF2 phosphorylation and nuclear translocation to up-regulate the expression of fibrosis-related proteins (COL1A, COL3A, TGF-ß1 and α-SMA). Our result suggests that suppression of ROS/JNK signaling pathway is a critical mechanism for developing a novel therapeutic strategy against atrial fibrillation.

BACKGROUND: Preoperative skin preparation is associated with surgical site infection (SSI). Traditional preoperative shaving fails to reduce the risk of SSI. The efficacy of 2% chlorhexidine for preoperative skin preparation in percutaneous coronary intervention (PCI) is sketchy. The aim of this trial was to evaluate whether preoperative skin preparation performed with chlorhexidine was not inferior to a conventional hair removal method. METHODS: Seventy-eight patients undergoing PCI were randomized into 2 groups of 39 patients, receiving either single sterilization with 2% chlorhexidine or hair shaving respectively between July 2016 and October 2016. The primary endpoints were wound infection rate and bacterial counts. Secondary endpoints were rate of SSI and adverse effects of 2% chlorhexidine. RESULTS: The results showed that 2% chlorhexidine significantly reduced the colonization of Staphylococcus aureus (Pâ=â.032), S epidermidis (Pâ=â.000), and miscellaneous bacteria (Pâ=â.244) in comparison with hair shaving, respectively. Redness in 24âhours after surgery was observed in 6 patients in the control group (15.4%) and 5 patients (12.8%) in 2% chlorhexidine group. There was no statistically significant difference in SSI rate between 2 skin preparations. CONCLUSION: In PCI, preoperative skin preparation with 2% chlorhexidine was not inferior to conventional hair shaving in terms of the wound infection rate and SSI rate.

BACKGROUND: Immediate-release carvedilol requires twice-daily dosing and may have low treatment compliance. We assessed the efficacy of a new formulation of once-daily extended-release carvedilol (carvedilol ER) on systolic blood pressure (SBP) and diastolic blood pressure (DBP) among patients with hypertension in this double-blind, randomized, placebo-controlled trial. METHODS: A total of 134 patients with untreated or uncontrolled hypertension were randomly assigned in a 1:1:1 ratio to receive placebo, low-dose carvedilol ER, or high-dose carvedilol ER for 8 weeks. The primary endpoint was the reduction in office SBP at 8 weeks. Secondary endpoints included the reduction in office DBP and the proportion of patients with blood pressure (BP) < 140/90 mm Hg. RESULTS: In the intention-to-treat population, placebo-adjusted changes in SBP/DBP were -2.9 mm Hg [95% confidence interval (CI), -9.6 to 3.7]/-1.7 mm Hg (95% CI, -5.6 to 2.3) and -4.9 mm Hg (95% CI, -11.5 to 1.7)/-3.4 mm Hg (95% CI, -7.3 to 0.5) for low-dose carvedilol ER and high-dose carvedilol ER, respectively. In the per-protocol population, high-dose carvedilol ER was associated with a significant DBP reduction [placebo-adjusted difference, -4.7 mm Hg (95% CI, -8.8 to -0.5); adjusted p = 0.026]. There was a gradational improvement in BP control with carvedilol ER (25%, 37%, and 48% for placebo, low-dose carvedilol ER, and high-dose carvedilol ER, respectively; linear-by-linear association p = 0.028). There were no differences in safety among the three groups. CONCLUSIONS: Carvedilol ER, though well tolerated, did not result in a greater reduction in either SBP or DBP compared with placebo.
BACKGROUND: Procalcitonin (PCT) has been widely investigated as an infection biomarker. The study aimed to prove that serum PCT, combining with other relevant variables, has an even better sepsis-detecting ability in critically ill patients. METHODS: We conducted a retrospective cohort study in a regional teaching hospital enrolling eligible patients admitted to intensive care units (ICU) between July 1, 2016, and December 31, 2016, and followed them until March 31, 2017. The primary outcome measurement was the occurrence of sepsis. We used multivariate logistic regression analysis to determine the independent factors for sepsis and constructed a novel PCT-based score containing these factors. The area under the receiver operating characteristics curve (AUROC) was applied to evaluate sepsis-detecting abilities. Finally, we validated the score using a validation cohort. RESULTS: A total of 258 critically ill patients (70.9±16.3 years; 55.4% man) were enrolled in the derivation cohort and further subgrouped into the sepsis group (n = 115) and the non-sepsis group (n = 143). By using the multivariate logistic regression analysis, we disclosed five independent factors for detecting sepsis, namely, "serum PCT level," "albumin level" and "neutrophil-lymphocyte ratio" at ICU admission, along with "diabetes mellitus," and "with vasopressor." We subsequently constructed a PCT-based score containing the five weighted factors. The PCT-based score performed well in detecting sepsis with the cut-points of 8 points (AUROC 0.80; 95% confidence interval (CI) 0.74-0.85; sensitivity 0.70; specificity 0.76), which was better than PCT alone, C-reactive protein and infection probability score. The findings were confirmed using an independent validation cohort (n = 72, 69.2±16.7 years, 62.5% men) (cut-point: 8 points; AUROC, 0.79; 95% CI 0.69-0.90; sensitivity 0.64; specificity 0.87). CONCLUSIONS: We proposed a novel PCT-based score that performs better in detecting sepsis than serum PCT levels alone, C-reactive protein, and infection probability score.

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.
ABSTRACT: The aim of this study was to examine atrial fibrillation (AF) patients' preferences regarding oral anticoagulation (OAC) characteristics and to investigate differences across 5 different countries. A multicenter discrete choice experiment was conducted in Germany, Sweden, Switzerland, Spain, and Taiwan. Study sites enrolled patients with nonvalvular AF who received continuous OAC therapy. The discrete choice experiment design considered the following 4 attributes with 2 attribute levels each: need for bridging (yes/no), interactions with food/alcohol (yes/no), need for regular international normalized ratio (INR) assessments, and frequency of intake (once/twice daily). Generally, patients (n = 1391) preferred treatment alternatives that were characterized by "no need of bridging," "no need for regular INR controls," "no interactions with food/alcohol," and "once daily intake." For this desired treatment regimen, patients were willing to accept a substantially higher travel distance/time. German patients with AF were strongly impacted in their hypothetical treatment decision by the frequency of intake (37.5%). Swedish patients on the other hand gave little importance to intake frequency (12.6%). In Switzerland, patients were especially concerned with food/alcohol interactions of the medication (34.7%), whereas this was the least important attribute for Taiwanese patients (18.9%), who ascribed the most homogenous importance to the different treatment attributes overall. In Spain, the need for regular INR assessments especially impacted the patient's treatment decision (31.9%). Patients of all countries attributed a moderate importance to the need for bridging (25.9%-34.2%). These findings may facilitate country-specific consideration of patients' preferences regarding OAC therapy, potentially increasing treatment acceptance on the patient's side with the ultimate goal of improving treatment adherence and persistence.

BACKGROUND: In recent years, considerable effort has been devoted to identifying genes that contribute to the risk of coronary artery disease (CAD). Genetic factors can be used to identify individuals who have additional genetic risks. Genetic variations might contribute to cardiovascular disease differentially in men and women. Dipeptidyl peptidase-4 (DPP-4) may be involved in the development of atherosclerotic diseases. OBJECTIVES: To examine the associations between genetic variations of DPP-4 in men and women with CAD. MATERIAL AND METHODS: In this case-control study, blood samples of patients with angiographically documented CAD and of those without CAD were collected. We focused on the DPP-4 gene (rs7608798 and rs3788979 polymorphisms) to assess the association of single nucleotide polymorphisms (SNPs) and the risk of CAD. RESULTS: We identified 1 SNP (rs3788979) that was significantly related to angiographic CAD in women (odds ratio (OR) = 2.437; p = 0.019). Moreover, the SNP (rs7608798) seemed to have a protective effect (OR = 0.291; p = 0.032). We did not find an association between CAD risk factors and DPP-4 polymorphisms. Our study is the first to demonstrate that CAD pathogenesis is influenced by gender differences in polymorphisms in the DPP-4 gene. CONCLUSIONS: This study provides new information on the association of DPP-4 polymorphisms with the risk of CAD in the Taiwanese population, especially in women. Further studies should be performed to verify this association.

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.

BACKGROUND: The aim of this study was to evaluate early and long-term clinical and laboratory findings in patients with resistant hypertension secondary to aldosterone-producing adenoma (APA) treated with radiofrequency ablation (RFA). METHODS: From July 2009 to September 2017, eight adult patients underwent percutaneous computed tomography (CT)-guided RFA for APA. The safety, efficacy and complications of the procedure were determined. Blood pressure (BP), number of antihypertensive agents, serum potassium, plasma aldosterone and aldosterone-to-renin ratio (ARR) were analyzed before RFA and immediately, short-term and long-term after RFA. RESULTS: The technical success rate was 100%. Two patients developed minor complications but there were no major complications. Clinical improvement was achieved immediately and short-term after RFA. In the long-term (mean follow-up duration of 6.7 ± 2.1 years) there were significant improvements in systolic (from 162.3 mmHg ± 18.6 to 125 mmHg ± 16.1, p = 0.02) and diastolic (from 96.3 mmHg ± 12.7 to 68.5 mmHg ± 6.3, p = 0.02) BP, with a significant reduction in the number of antihypertensive agents (from 3.33 ± 0.82 to 1.33 ± 1.21, p = 0.02). Hypokalemia improved significantly (serum potassium from 2.16 meq/L ± 0.22 to 4.34 meq/L ± 0.54, p = 0.04). Although the plasma aldosterone level decreased significantly, ARR did not (from 100.7 ± 124.4 to 28.7 ± 30.7 ng/dL-per-ng/mL/h, p = 0.13). Hypertension was cured in 33.3% of the patients, and the BP of all patients was more easily controlled regardless of the plasma aldosterone and renin status. CONCLUSIONS: CT-guided percutaneous RFA appears to be effective and safe to treat patients with APA, with clinical improvements in BP, reduced number of antihypertensive agents, and normalization of serum potassium level. These favorable outcomes persisted in short-term and long-term follow-up.
