Background: Serum D-dimer level has been associated with worsening outcomes in patients with acute myocardial infarction. This study aimed to explore the association between serum D-dimer level and clinical outcomes in Taiwanese patients with acute myocardial infarction. Methods: We analyzed Tri-Service General Hospital-Coronary Heart Disease registry data related to patients with acute myocardial infarction who were admitted between January 2014 and December 2018. A total of 748 patients were enrolled and categorized into high (≥ 495 ng/ml) and low (< 495 ng/ml) D-dimer groups. The primary endpoint was in-hospital mortality, and secondary endpoints were post-discharge mortality and post-discharge major adverse cardiovascular events. Results: Overall, 139 patients died, with 77 from cardiovascular causes and 62 from non-cardiovascular causes. In-hospital mortality was higher in the high D-dimer group than in the low D-dimer group. Among the patients alive at discharge, those with a high D-dimer level had higher cardiovascular mortality and future major adverse cardiovascular events than those with a low D-dimer level. Multivariate Cox regression analysis revealed that higher serum D-dimer levels were significantly associated with higher risks of in-hospital mortality [hazard ratio (HR) = 1.11; 95% confidence interval (CI), 1.06-1.16, p < 0.001], subsequent cardiovascular mortality after discharge (HR = 1.15; 95% CI, 1.08-1.22, p < 0.001), and major adverse cardiovascular events (HR = 1.10; 95% CI, 1.04-1.16, p < 0.001). Conclusions: This is the first study in Taiwan to demonstrate that a higher baseline serum D-dimer level was independently associated with higher risks of in-hospital mortality, post-discharge mortality, and major adverse cardiovascular events in patients with acute myocardial infarction.

BACKGROUND: Lifestyle modification is an essential component of prevention and management of hypertension. Existing instruments in Taiwan focus on assessing lifestyle modifications by evaluating medication adherence or confidence in controlling blood pressure. However, other self-care activities, such as diet, physical activity, weight management, smoking, and alcohol consumption are also important. The Hypertension Self-Care Activity Level Effects (H-SCALE) is one such instrument, but there are no similar tools available in Taiwan. AIM: This study aimed to translate the H-SCALE into Chinese and test its validity, and reliability in a sample of adults with hypertension. METHODS: The English version of the 31-item H-SCALE was translated into Chinese using the forward-backward method. The content validity index (CVI) of the translated scale was determined by five experts in hypertension. Item analysis was conducted with a pilot sample of 20 patients with hypertension. Cronbach's α was used to establish the internal consistency reliability for the Chinese version of the H-SCALE (H-SCALE-C). Exploratory factor analysis (EFA) explored the structure of the H-SCALE-C. Additionally, construct validity was examined with confirmatory factor analysis (CFA). Patients with hypertension were recruited by convenience sampling from a cardiovascular outpatient clinic of a medical center in northern Taiwan. A total of 318 patients met the inclusion criteria and participated in factor analysis in the study. RESULTS: Pilot testing of the scale items indicated most patients could not accurately estimate the number of days of alcohol consumption for the previous week. Therefore, three alcohol-related items were removed. The adaptation resulted in a 28-item H-SCALE-C. EFA revealed a 4-factor solution with 13 items that explained 63.93% of the total variance. CFA indicated a good fit for a 4-factor model and construct validity was acceptable. Internal consistency reliability was acceptable (Cronbach's alpha for the four subscales ranged from 0.65 to 0.94). Convergent validity was acceptable, and discriminant validity was significant. CONCLUSIONS: The H-SCALE-C is a valid, reliable tool for promptly assessing life-style activities for patients with hypertension in Taiwan. The instrument is suitable for assisting healthcare providers in evaluating self-care activities, which could be used to facilitate lifestyle modifications for patients with hypertension.

Patients with hypertension (HTN) are at increased risk of developing cardiovascular disease, which can be reduced with blood pressure (BP) control. Anxiety can contribute to high BP and low heart rate variability (HRV). Although relationships between social support, self-rated health-status (SRHS), anxiety and measures of HRV and BP have been suggested, they have not been clearly established. This cross-sectional correlational study aimed to 1) examine relationships between social support, SRHS, and anxiety; and 2) examine if HRV mediated relationships between anxiety symptoms and BP. Patients with primary HTN were recruited from a cardiovascular outpatient clinic using convenience sampling (N = 300). Data included scale scores for SRHS, social support, and anxiety (Hospital Anxiety and Depression Scale). A handheld limb-lead electrocardiogram monitor measured HRV, using the ratio of low-frequency bands to high-frequency bands; an automatic sphygmomanometer measured systolic and diastolic blood pressure (SBP and DBP, respectively). Path analysis of structural equation models examined relationships between variables; the bootstrap method examined the mediating effects of HRV. Analysis showed scores for SRHS and social support had a direct effect on anxiety scores. Scores for anxiety directly affected HRV and BP. HRV also had a direct effect on BP. Bootstrapping indicated HRV mediated the relationship between anxiety symptoms and BP. The final model indicated SRHS, social support, and anxiety symptoms together explained 80% of SBP and 33% of DBP. These findings suggest HRV could be used to measure the effectiveness of strategies aimed at reducing anxiety and improving control of BP.

The intracellular sensor protein complex known as the NACHT, LRR, and PYD domain-containing protein 3 (NLRP3) inflammasome plays a crucial role in regulating inflammatory diseases by overseeing the production of interleukin (IL)-1ß and IL-18. Targeting its abnormal activation with drugs holds significant promise for inflammation treatment. This study highlights LCZ696, an angiotensin receptor-neprilysin inhibitor, as an effective suppressor of NLRP3 inflammasome activation in macrophages stimulated by ATP, nigericin, and monosodium urate. LCZ696 also reduces caspase-11 and GSDMD activation, lactate dehydrogenase release, propidium iodide uptake, and the extracellular release of NLRP3 and apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) in ATP-activated macrophages, suggesting a potential mitigation of pyroptosis. Mechanistically, LCZ696 lowers mitochondrial reactive oxygen species and preserves mitochondrial integrity. Importantly, it does not significantly impact NLRP3, proIL-1ß, inducible nitric oxide synthase, cyclooxygenase-2 expression, or NF-κB activation in lipopolysaccharide-activated macrophages. LCZ696 partially inhibits the NLRP3 inflammasome through the induction of autophagy. In an in vivo context, LCZ696 alleviates NLRP3-associated colitis in a mouse model by reducing colonic expression of IL-1ß and tumor necrosis factor-α. Collectively, these findings suggest that LCZ696 holds significant promise as a therapeutic agent for ameliorating NLRP3 inflammasome activation in various inflammatory diseases, extending beyond its established use in hypertension and heart failure treatment.

BACKGROUND: Poor functional status relating to heart failure (HF) negatively affects health-related quality of life (HRQOL). Patients with HF, especially those with New York Heart Association (NYHA) Class III or IV HF, often exhibit poor HRQOL because of physical limitations and HF-related symptoms. Although sense of coherence (SOC) has been reported to be a determinant of HRQOL, its role as a mediator between functional status and HRQOL remains unclear, and few studies have explored the prevalence of HF in patients in NYHA Classes I and II. PURPOSE: This study was designed to investigate SOC as a mediator between different functional status classes and HRQOL in patients with HF. METHODS: A cross-sectional study was conducted on patients with HF recruited from a hospital in northern Taiwan from April 2020 to September 2020. The Minnesota Living with Heart Failure Questionnaire and a questionnaire on sociodemographic characteristics; functional classification in terms of NYHA Classes I, II, and III; and SOC were administered. The PROCESS v3.5 (by Andrew F. Hayes) macro was applied to analyze the effects, and Model 4 was used to examine the mediating role of SOC on the relationship between NYHA functional class and HRQOL. RESULTS: Of the 295 participants, SOC was found to mediate the effects of functional status on HRQOL more significantly in patients in Class II than those in Class III but not more significantly in patients in Class I than those in Class III. A weaker mediating effect of SOC was noted on the relationship between functional status and HRQOL in patients with HF in NYHA Class II than those in Class III. CONCLUSIONS: In patients with HF, poor functional status often reduces HRQOL significantly. SOC mediates the relationship between functional status and HRQOL more significantly in those in NYHA Class II than those in Class III. Nursing staff should work to increase patients' SOC by strengthening their coping capacity and improving their functional status to improve their HRQOL.

AIMS: Blood pressure control requires medication adherence and lifestyle modifications. Social cognitive theory suggests social support, psychological adaptation, and self-efficacy can reinforce lifestyle modifications. This study investigated if self-efficacy was a mediator between self-rated health status (SRHS), social support, depressive symptoms, anxiety, and self-care among patients with hypertension. METHOD AND RESULTS: This cross-sectional study recruited patients with primary hypertension by convenience sampling (N = 318) from an outpatient cardiology clinic. Data included participant characteristics and self-report scales for social support, SRHS, anxiety, depressive symptoms, Self-efficacy and self-care diet quality and weight management. We used path analysis to test the hypothesized model. The mean age of participants was 63.91 ± 11.80 years. Mean scale scores for social support and depressive symptoms were 54.23 ± 13.26 and 6.14 ± 3.14, respectively; SRHS was 66.91 ± 13.80, self-efficacy was 34.31 ± 11.62, self-care for diet quality and weight management were 36.50 ± 13.19 and 27.38 ± 8.64, respectively. Bootstrapping demonstrated self-efficacy was the mediator between social support and self-care for diet quality and weight management; depressive symptoms mediated the relationship between social support and self-efficacy. In addition, the variable of depressive symptoms was also a mediator between SRHS and self-efficacy. The final model showed SRHS, social support, depressive symptoms, and self-efficacy explained 28% of self-care. CONCLUSION: Our findings suggest developing theory-based interventions for patients with hypertension that provide education and/or psychological support for increasing patients' self-efficacy and reducing depressive symptoms simultaneously to facilitate their long-term self-care behaviours.

The intracellular sensor NACHT, LRR, and PYD domain-containing protein 3 (NLRP3) inflammasome controls caspase-1 activity and the maturation and release of the cytokines interleukin (IL)-1ß and IL-18. The NLRP3 inflammasome has attracted the attention of the pharmaceutical industry because it promotes the pathogenesis of many diseases, making it a promising target for drug development. Litsea cubeba (Lour.) is a plant traditionally used as a seasoning in Taiwan and in other Asian countries. In this study, we investigated the inhibitory activity of the leaves of L. cubeba against the NLRP3 inflammasome. We found that the ethanol extract of L. cubeba leaves (MLE) inhibited the NLRP3 inflammasome in macrophages by reducing caspase-1 activation and IL-1ß secretion. MLE reduced pyroptosis in macrophages and inhibited the release of NLRP3 and apoptosis-associated speck-like protein containing a CARD (ASC). In a mechanistic study, MLE reduced mitochondrial reactive oxygen species (ROS) production and preserved mitochondrial integrity, which led to reduced mitochondrial DNA release into the cytosol. MLE did not reduce the expression levels of NLRP3, IL-1ß precursor or TNF-α in lipopolysaccharide (LPS)-activated macrophages. These results indicated that MLE inhibited the NLRP3 inflammasome by suppressing the activation signals of the NLRP3 inflammasome but not by reducing the priming signal induced by LPS. In addition, oral administration of MLE (20-80 mg/kg) ameliorated dextran sulfate sodium (DSS)-induced colitis in a mouse model. Notably, mice that received MLE (1 and 2 g/kg) daily for 7 days did not exhibit visible side effects. Gas chromatography-mass spectrometry (GC-MS) analysis found that α-Terpinyl acetate (27.2%) and 1,8-Cineole (17.7%) were the major compounds in MLE. These results indicated that L. cubeba leaves have the potential to be a nutraceutical for preventing and improving NLRP3 inflammasome-related diseases.

Aberrant activation of the NLRP3 inflammasome promotes the pathogenesis of many inflammatory diseases. The development of the NLRP3 inflammasome inhibitors from existing drugs for new therapeutic purposes is becoming more important. Candesartan is an angiotensin II receptor antagonist widely used as a blood pressure-lowering drug; however, the inhibitory potential of candesartan on the NLRP3 inflammasome has not yet been investigated. We demonstrated that candesartan significantly inhibited the NLRP3 inflammasome and pyroptosis in macrophages. Mechanistic analysis revealed that candesartan inhibited the expression of NLRP3 and proIL-1ß by suppressing NF-κB activation and reducing the phosphorylation of ERK1/2 and JNK1/2. Candesartan reduced mitochondrial damage and inhibited the NLRP3 inflammasome assembly by suppressing NLRP3 binding to PKR, NEK7 and ASC. In addition, candesartan inhibited IL-1ß secretion partially through autophagy induction. Furthermore, oral administration of candesartan reduced peritoneal neutrophil influx, NLRP3 and ASC expression in peritoneal cells, and lavage fluid concentrations of active caspase-1, IL-1ß, IL-6 and MCP-1 in uric acid crystal-injected mice. These results indicated that candesartan has board anti-inflammatory effects and has the potential to be repositioned to ameliorate inflammatory diseases or NLRP3-associated complications.

BACKGROUND: Hypertension is a major risk factor for cardiovascular diseases, which contributes to the worldwide mortality rate. Successful blood pressure control requires adherence to medications and lifestyle modifications. However, motivating patients with primary hypertension to change and sustain behaviors long-term is challenging. A web-based self-care program centered on self-efficacy theory could provide feedback for effective control of blood pressure. PURPOSE: To examine the effect of a web-based self-care program for patients with primary hypertension on cardiovascular risk-factors (pulse pressure and lipids), self-efficacy, and self-care behaviors (medication adherence and lifestyle). DESIGN: A two-armed randomized controlled trial with 3-month and 6-month follow-ups. SETTING AND PARTICIPANTS: A total of 222 patients with primary hypertension were recruited between February 2017 and August 2018 at a cardiology clinic of a medical center in Taipei, Taiwan. METHODS: Eligible patients were randomized by permuted block randomization into the intervention group (n = 111) and control group (n = 111). Patients in the intervention group received a 6-month web-based self-care program, based on the theory of self-efficacy, while patients in the control group received usual care. Baseline and outcome measures (3 and 6 months) included self-efficacy, evaluated with the Chinese version of the 6-item Self-Efficacy for Managing Chronic Diseases (SEMC6), self-care, using subscales of the Hypertension Self-Care Activity Level Effects Scale (H-SCALE) for lifestyle and medication adherence, and blood pressure and serum lipid data, collected through web-based self-reports and chart review. Generalized estimating equations evaluated the effects of the intervention. FINDINGS: At baseline, the control group had higher scores on the SEMC6, and lower cholesterol (HDL) compared with the intervention group (t = -2.70, p < 0.05; and t = 1.76, p < 0.05, respectively). Pulse pressure decreased significantly (ß = -20.30, 95% CI -23.76, -16.83), and serum triglycerides and low-density lipoprotein cholesterol levels were significantly lower compared with controls at 6 months (all p < 0.001). At 6 months, the intervention group had significantly higher mean scores for the SEMC6 compared with the control group (ß = 21.84, 95% confidence interval [CI] 19.25, 24.42) and H-SCALE subscale for medication adherence, diet, weight management, and physical activity compared with controls at 6 months (all, p < 0.001). CONCLUSIONS AND CLINICAL RELEVANCE: The greatest benefit of this program was allowing participants to immediately consult with the researchers about self-care issues via the website. Lifestyles vary from person to person; therefore, the individuality of each participant was considered when providing feedback. We provided devising interventions for participants that would increase their confidence in self-care for hypertension and ultimately achieve home blood pressure control. We encourage incorporating this program into standard clinical care for patients with hypertension.

Cardiovascular events such as myocarditis following mRNA COVID-19 vaccination are increasing. We present a 67-year-old postmenopausal woman with Takotsubo Syndrome and Graves' disease after mRNA COVID-19 vaccination. She developed chest pain and shortness of breath one week after vaccination. An electrocardiogram revealed ST elevation in the precordial leads. Coronary angiography revealed the absence of obstructive coronary artery disease, and the left ventriculography showed a typical feature with apical ballooning. Laboratory workup showed the elevation of free T4 and thyrotropin receptor antibodies. It was presumed that Takotsubo Syndrome and Graves' disease were probably related to the COVID-19 mRNA vaccination. The patient was treated with low-dose bisoprolol, diuretics, carbimazole, and steroid and discharged uneventfully. The mRNA COVID-19 vaccination is still safe and effective to defend against COVID-19 pandemic. However, clinicians should be aware of the possible cardiovascular adverse events other than myocarditis following vaccination.

OBJECTIVES: The choice of optimal antithrombotic therapy in atrial fibrillation (AF) patients with acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) remains controversial. The aim of this longitudinal cohort study is to investigate the prescribing pattern of antithrombotic regimen in different cohorts and its subsequent impact. SETTING AND DESIGN: Longitudinal data from the Tri-Service General Hospital-Coronary Heart Disease (TSGH-CHD) registry, between January 2016 and August 2018 was screened. PARTICIPANTS AND METHOD: Patients with prior history of nonvalvular AF, who had ACS presentation or underwent PCI were selected, and these patients were divided into cohort 1 and cohort 2, according to the index date of antithrombotic prescription before and after the PIONEER AF-PCI study. PRIMARY AND SECONDARY OUTCOMES: The primary safety endpoints were composites of major bleeding and/or clinically relevant non-major bleeding. The secondary efficacy endpoints included the occurrence of all-cause mortality, stroke/systemic embolization, nonfatal myocardial infarction (MI), and >30-days coronary revascularization. RESULTS: A total of 121 patients were included into analysis (cohort 1=35; cohort 2=86). Comparing with cohort 1, the prescription rate of triple antithrombotic therapy (TAT) increased from 17.1 to 38.4%, especially the regimen with dual antiplatelet therapy (DAPT) plus low-dose non-vitamin-K dependent oral anticoagulation (NOAC). However, the prescription rate of dual antithrombotic therapy (DAT) decreased (14.3-10.5%), as well as the prescription rate of DAPT (68.6-51.2%). These changes of antithrombotic prescription across different cohorts were not associated with risk of adverse safety (HR= 0.87; 95% CI, 0.42-1.80, p=0.710) and efficacy outcomes (HR=0.96; 95% CI, 0.40-2.32, p=0.930). CONCLUSIONS: Entering the NOAC era, the prescription of TAT increased alongside the decrease in DAT. As the prescription rate of DAPT without anticoagulation remained high, future efforts are mandatory to improve the implementation of guidelines and clinical practice.

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.

For patients with acute myocardial infarction scheduled to undergo percutaneous coronary stent implantation, in most cases a drug-eluting stent is recommended as the first choice for treatment. However, there is a lack of research on the effectiveness of bare-metal stents and drug-eluting stents on patients with different types of myocardial infarction. Our objective was to explore the effects of bare-metal stents and drug-eluting stents on patients with different types of myocardial infarction in terms of major cardiovascular incidents. This retrospective cohort study included 934 patients with myocardial infarction undergoing coronary artery stent implantation for the first time at the cardiac catheter room of the Tri-Service General Hospital in the Neihu District between 2014 and 2018. Patients' information, including demographic data, laboratory data, cardiac echocardiography results, and angiocardiography results, was collected by reviewing medical records. Cox proportional hazards regression was used to adjust the potential confounding factors, and the adjusted data were then used to compare the correlation between different types of stents and major cardiovascular incidents in patients with ST-elevation myocardial infarction and non-ST-elevation myocardial infarction. After the confounding factors were adjusted, in patients with ST-elevation myocardial infarction receiving a drug-eluting stent compared with those receiving a bare-metal stent, it was found that the mortality risk was lower in terms of all causes of death (Adj-HR = 0.26, 95% CI = 0.14-0.48, p < 0.001) and cardiogenic death (Adj-HR = 0.20, 95% CI = 0.08-0.55, p = 0.002), the risk of non-fatal myocardial infarction was lower (Adj-HR = 0.17, 95% CI = 0.04-0.73, p = 0.017), and there was no difference in the risk of revascularization at the lesion site (Adj-HR = 0.59, 95% CI = 0.24-1.43, p = 0.243). It terms of the findings in patients with non-ST-elevation myocardial infarction, those receiving a drug-eluting stent had a lower risk of revascularization at the lesion site (Adj-HR = 0.48, 95% CI = 0.24-0.97, p = 0.04); however, there was no difference in the mortality risk in terms of all causes of death (Adj-HR = 0.71, 95% CI = 0.37-1.35, p = 0.296) or cardiogenic death (Adj-HR = 0.59, 95% CI = 0.18-1.90, p = 0.379),or in the risk of non-fatal myocardial infarction (Adj-HR = 0.27, 95% CI = 0.06-1.25, p = 0.093). Compared with bare-metal stents, drug-eluting stents provide better protection against death to receivers with ST-elevation myocardial infarction; however, this protection is decreased in receivers with non-ST-elevation myocardial infarction. It is recommended that for patients with non-ST-elevation myocardial infarction who are indicated to receive a drug-eluting stent, the clinical effectiveness of the treatment must be considered.

BACKGROUND: Atrial fibrillation (AF) is related to a variety of chronic diseases and life-threatening complications. It is estimated that by 2050, there will be 72 million patients with AF in Asia, of which 2.9 million will have AF-associated stroke. AF has become a major issue for health care systems. OBJECTIVE: We aimed to evaluate the effects of a web-based integrated management program on improving coping strategies, medication adherence, and health-related quality of life (HRQoL) in patients with AF, and to detect the effect on decreasing readmission events. METHODS: The parallel-group, single-blind, prospective randomized controlled trial recruited patients with AF from a medical center in northern Taiwan and divided them randomly into intervention and control groups. Patients in the intervention group received the web-based integrated management program, whereas those in the control group received usual care. The measurement tools included the Brief Coping Orientation to Problems Experienced (COPE) scale, Medication Adherence Rating Scale (MARS), the three-level version of the EuroQoL five-dimension self-report questionnaire (EQ-5D-3L), and readmission events 2 years after initiating the intervention. Data were collected at 4 instances (baseline, 1 month, 3 months, and 6 months after initiating the intervention), and analyzed with generalized estimating equations (GEEs). RESULTS: A total of 231 patients were recruited and allocated into an intervention (n=115) or control (n=116) group. The mean age of participants was 73.08 (SD 11.71) years. Most participants were diagnosed with paroxysmal AF (171/231, 74%), and the most frequent comorbidity was hypertension (162/231, 70.1%). Compared with the control group, the intervention group showed significantly greater improvement in approach coping strategies, medication adherence, and HRQoL at 1, 3, and 6 months (all P<.05). In addition, the intervention group showed significantly fewer readmission events within 2 years (OR 0.406, P=.03), compared with the control group. CONCLUSIONS: The web-based integrated management program can significantly improve patients' coping strategy and medication adherence. Therefore, it can empower patients to maintain disease stability, which is a major factor in improving their HRQoL and reducing readmission events within 2 years.

BACKGROUND: The Taiwan Society of Cardiology (TSOC) has established multicenter registries for coronary artery disease (CAD) to investigate clinical characteristics, management and risks for mortality. However, the impacts of newly-emerged evidence-based therapies, including the use of drug-eluting stents (DESs), on patients with CAD in Taiwan remain unclear. METHODS: The Tri-Service General Hospital-Coronary Heart Disease (TSGH-CHD) registry is a single-center, prospective, longitudinal registry in Taiwan containing data from 2014-2016. Individuals who were admitted for coronary angiography were enrolled. Patient profiles, management and in-hospital outcome data were collected. RESULTS: We included 3352 patients: 2349 with stable angina and 1003 with acute coronary syndrome (ACS). In the stable angina group, both patients receiving stenting and those receiving medical treatment had a 0.7% mortality rate; DESs were used in 70.4% of the patients receiving stenting. In the ACS group, the patients receiving stenting and those receiving medical treatment had a 4.9% and 10.7% mortality rate, respectively; DESs were used in 63.1% of the patients receiving stenting. In the 2008-2010 Taiwan ACS registry, DESs were used in only 28% of all stenting procedures, and the estimated hospital mortality rate was 1.8%. Multivariate analysis indicated that older age, prior stroke, and cardiogenic shock on admission were associated with an increased risk of in-hospital mortality in the ACS group. CONCLUSIONS: Compared with the Taiwan ACS cohort, the TSGH-CHD registry revealed increased DES use and increased disease complexity and severity after 2010. Although unlikely to significantly improve survival, interventionists seemed to perform high-risk procedures for complex CAD more often in the new DES era.

BACKGROUND: Delayed diagnosis or misdiagnosis of acute myocardial infarction (AMI) is not unusual in daily practice. Since a 12-lead electrocardiogram (ECG) is crucial for the detection of AMI, a systematic algorithm to strengthen ECG interpretation may have important implications for improving diagnosis. AIMS: We aimed to develop a deep learning model (DLM) as a diagnostic support tool based on a 12-lead electrocardiogram. METHODS: This retrospective cohort study included 1,051/697 ECGs from 737/287 coronary angiogram (CAG)-validated STEMI/NSTEMI patients and 140,336 ECGs from 76,775 non-AMI patients at the emergency department. The DLM was trained and validated in 80% and 20% of these ECGs. A human-machine competition was conducted. The area under the receiver operating characteristic curve (AUC), sensitivity, and specificity were used to evaluate the performance of the DLM. RESULTS: The AUC of the DLM for STEMI detection was 0.976 in the human-machine competition, which was significantly better than that of the best physicians. Furthermore, the DLM independently demonstrated sufficient diagnostic capacity for STEMI detection (AUC=0.997; sensitivity, 98.4%; specificity, 96.9%). Regarding NSTEMI detection, the AUC of the combined DLM and conventional cardiac troponin I (cTnI) increased to 0.978, which was better than that of either the DLM (0.877) or cTnI (0.950). CONCLUSIONS: The DLM may serve as a timely, objective and precise diagnostic decision support tool to assist emergency medical system-based networks and frontline physicians in detecting AMI and subsequently initiating reperfusion therapy.

PURPOSE: Secondary prevention of coronary artery disease, self-management behavior, and blood pressure control are important to cardiovascular event prevention and promotion of quality of life (QOL), but they are underutilized. The purpose of this study was to investigate the effects of a self-efficacy theory-based health information technology intervention implemented through blood control and patient self-management. DESIGN: A clinical randomized waitlist-controlled trial. METHODS: The study was conducted at a medical center in Taipei, Taiwan. A total of 60 subjects were randomly assigned to either the immediate intervention (experimental) group or the waitlist control group. The primary endpoint was systolic blood pressure at 3 months; secondary end points included self-management behavior and QOL. Treatment for the immediate intervention group lasted 3 months, while the waitlist control group received routine care for the first 3 months, at which point they crossed over to the intervention arm and received the same intervention as the experimental group for another 3 months. Both groups were evaluated by questionnaires and physiological measurements at both 3 and 6 months postadmission. The results were analyzed using generalized estimating equations. RESULTS: Systolic blood pressure significantly improved for the intervention group participants at 3 months, when there was also significant improvement in self-management behavior and QOL. There was no significant or appreciable effect of time spent in the waitlist condition, with treatments in the two conditions being similarly effective. CONCLUSION: The use of a theory-based health information technology treatment compared with usual care resulted in a significant improvement in systolic blood pressure, self-management behavior, and QOL in patients with coronary artery disease. CLINICAL RELEVANCE: This treatment would be a useful strategy for clinical care of cardiovascular disease patients, improving their disease self-management. It also may help guide further digital health care strategies during the COVID-19 pandemic.

BACKGROUND: New-onset atrial fibrillation (NOAF) in acute coronary syndrome (ACS) may be associated with a poor prognosis. However, whether restoring sinus rhythm (SR) at discharge in patients with ACS improves outcomes remains unknown. METHODS: A total of 552 patients with ACS at an emergency department during 2011-2016 were enrolled. According to documented electrocardiography at admission and medical records, the patients were classified into without atrial fibrillation (WAF), NOAF, and prior atrial fibrillation (PAF) groups. Major adverse events (MAEs) were defined as cardiac death, recurrent myocardial infarction, heart failure requiring hospitalization, target lesion revascularization, and stroke. The mean follow-up period of MAEs was 25 ± 15 months. RESULTS: Compared with the NOAF and PAF groups, the WAF group was younger and had a significantly lower heart rate, prior stroke rate, CHA2DS2-VASc score, and lower Global Registry of Acute Coronary Events (GRACE) score in the emergency department (p < 0.001). The patients in the NOAF group had the highest incidence of MAEs (p < 0.001) during follow-up, and those whose SR was restored at discharge had a lower MAE rate than those with AF at discharge (p = 0.001). In multivariable analysis, prior myocardial infarction, GRACE score, use of beta-blockers, and restoring SR at discharge were independent predictors of MAEs in the NOAF group. CONCLUSIONS: The patients with ACS who presented with NOAF had worse outcomes than those with PAF or WAF. The patients with NOAF whose rhythm was restored to SR at discharge were associated with better outcomes than those with AF at discharge.

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.
