2023 TSOC-TACVPR-TACPAH Consensus Statement of the Rehabilitation on Patients with Pulmonary Hypertension.

In the past, patients with pulmonary hypertension (PH) were advised to avoid exercise due to concerns that it might strain cardiac function and exacerbate symptoms. However, recent evidence indicates that structured exercise programs can enhance outcomes and improve health-related quality of life for these patients. Consequently, exercise rehabilitation is now recommended in international guidelines as a key component of PH management.

Transmission line model as a digital twin for abdominal aortic aneurysm patients.

We investigated the potential of the transmission line model as a digital twin of aneurysmal aorta by comparatively analyzing how a uniform lossless tube-load model were fitted to the carotid and femoral artery tonometry waveforms pertaining to (i) 79 abdominal aortic aneurysm (AAA) patients vs their matched controls (CON) and (ii) 35 AAA patients before vs after endovascular aneurysm repair (EVAR). The uniform lossless tube-load model fitted the tonometry waveforms pertaining to AAA as well as CON and EVAR. In addition, the parameters in the tube-load model exhibited physiologically explainable changes: when normalized, both pulse transit time and reflection coefficient increased with AAA and decreased after EVAR, which can be explained by the increase in arterial compliance and the decrease in arterial inertance due to the aortic expansion associated with AAA.

Tissue inhibitor of metalloproteinase (TIMP)-1 predicts failure of recovery of ejection fraction in acute heart failure with reduced ejection fraction.

Background: Heart failure (HF) with improved ejection fraction (HFimpEF) is a recently identified phenotype of HF, which had better cardiovascular outcomes compared with persistent HF with reduced ejection fraction (HFrEF). The present study aimed to investigate the predictive value of tissue inhibitor of metalloproteinase (TIMP)-1 and matrix metalloproteinases-9 (MMP-9) in the recovery of left ventricular ejection fraction (LVEF).

Methods: Subjects who presented with acute decompensated HF and reduced LVEF of ≤40% were eligible for this study.

Exercise capacity-hemodynamics mismatch in elderly patients with pulmonary hypertension: A nationwide multicenter study from Taiwan Society of Cardiology Pulmonary Hypertension Registry (TAIPANS).

Background: Demographics of pulmonary hypertension (PH) has changed a lot over the past forty years. Several recent registries noted an increase in mean age of PH but only a few of them investigated the characteristics of elderly patients. Thus, we aimed to analyze the characteristics of PH in such a population in this study.

Examining arterial pulsation to identify and risk-stratify heart failure subjects with deep neural network.

Hemodynamic parameters derived from pulse wave analysis have been shown to predict long-term outcomes in patients with heart failure (HF). Here we aimed to develop a deep-learning based algorithm that incorporates pressure waveforms for the identification and risk stratification of patients with HF. The first study, with a case-control study design to address data imbalance issue, included 431 subjects with HF exhibiting typical symptoms and 1545 control participants with no history of HF (non-HF).

Cardiomyocyte Globotriaosylceramide Accumulation in Adult Male Patients with Fabry Disease and IVS4 + 919G>A GLA Mutation is Progressive with Age and Correlates with Left Ventricular Hypertrophy and Reduced Left Ventricular Ejection Fraction.

Background: While cardiovascular complications are the most common cause of mortality in Fabry disease, the relationship between globotriaosylceramide (GL-3) accumulation, the hallmark of Fabry cardiomyopathy, and cardiac hypertrophy has not been fully elucidated.

Methods: We developed unbiased stereology protocols to quantify the ultrastrcture of Fabry cardiomyopathy. Endomyocardial biopsies from 10 adult male enzyme replacement therapy naïve Fabry patients with IVS4 + 919G>A GLA mutation were studied.

TIMP-1 in the prognosis of patients who underwent coronary artery bypass surgery: a 12-year follow-up study.

Introduction: Matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) have been linked to clinical outcomes in patients with coronary artery disease (CAD). However, the prognostic value of TIMP-1 in patients with CAD who underwent coronary artery bypass grafting (CABG) has not been elucidated. We aimed to investigate the correlations of TIMP-1 with high-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-brain natriuretic peptide (NT-proBNP) in the long-term prognosis of consecutive patients who underwent CABG.

Advance Care Planning Affects End-of-Life Treatment Preferences Among Patients With Heart Failure: A Randomized Controlled Trial.

This study explored the effects of advance care planning interventions on end-of-life treatment decisions among patients with heart failure. The study design was a randomized controlled trial. An intervention involving a motivational video, a cartoon version educational brochure, and a guided discussion was implemented.

Symptom-limited exercise capacity is associated with long-term survival.

The prognostic value of exercise capacity has been demonstrated in subjects with established cardiovascular diseases. We aim to evaluate the independence of exercise capacity measured by treadmill exercise test (TET) in predicting long-term outcomes among various comorbidities. This study was conducted from January 2003 to December 2012 in a tertiary medical center in Taiwan.

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).

2023 Taiwan Society of Cardiology (TSOC) and Taiwan College of Rheumatology (TCR) Joint Consensus on Connective Tissue Disease-Associated Pulmonary Arterial Hypertension.

Background: Pulmonary arterial hypertension (PAH), defined as the presence of a mean pulmonary artery pressure > 20 mmHg, pulmonary artery wedge pressure ≤ 15 mmHg, and pulmonary vascular resistance (PVR) > 2 Wood units based on expert consensus, is characterized by a progressive and sustained increase in PVR, which may lead to right heart failure and death. PAH is a well-known complication of connective tissue diseases (CTDs), such as systemic sclerosis, systemic lupus erythematosus, Sjogren's syndrome, and other autoimmune conditions. In the past few years, tremendous progress in the understanding of PAH pathogenesis has been made, with various novel diagnostic and screening methods for the early detection of PAH proposed worldwide.

Improvement of clinical outcomes in patients undergoing peritoneal dialysis using hydroxymethylglutaryl-CoA reductase inhibitors: A systematic review and meta-analysis.

Background: It is unclear whether hydroxymethylglutaryl-CoA reductase inhibitor (statin) therapy decreases the risk of mortality and cardiovascular disease (CVD) in patients undergoing peritoneal dialysis (PD).

Methods: We performed a literature search of PubMed, Cochrane Library, Embase, and other databases for research publications up to June 2022. The outcomes of interest were fatal and nonfatal CVDs, all-cause mortality, and changes in the biochemical profiles.

Left Ventricular Apical Aneurysm in Fabry Disease: Implications for Clinical Significance and Risk Stratification.

Background A previously underrecognized phenotype of left ventricular apical aneurysm (LVAA) has been increasingly identified in Fabry disease. This study explored LVAA's clinical prevalence and its prognostic implications over a long-term follow-up. Methods and Results We retrospectively analyzed 268 consecutive patients with Fabry disease at a tertiary medical center.

Abdominal aortic aneurysm monitoring via arterial waveform analysis: towards a convenient point-of-care device.

Abdominal aortic aneurysms (AAAs) are lethal but treatable yet substantially under-diagnosed and under-monitored. Hence, new AAA monitoring devices that are convenient in use and cost are needed. Our hypothesis is that analysis of arterial waveforms, which could be obtained with such a device, can provide information about AAA size.

Risk stratification in patients with hypertrophic cardiomyopathy: Looking beyond the left side myocardial function.

Background: Patients with hypertrophic cardiomyopathy (HCM) have heterogeneous outcomes. As risk stratification mostly focuses on left-side myocardial function, we sought to investigate the prognostic value of right ventricular (RV) function in patients with HCM.

Methods: This retrospective cohort study included patients with HCM.

Effectiveness of salt substitute on cardiovascular outcomes: A systematic review and meta-analysis.

Hypertension-related death is the leading cause of mortality worldwide, making blood pressure (BP) control an important issue. Salt substitute is a non-pharmaceutical strategy to improve hypertension control. The goal of this study was to evaluate the effect of salt substitute on BP and cardiovascular disease.

Association between visit-to-visit blood pressure variability and adverse events in coronary artery disease patients after coronary intervention.

Blood pressure variability (BPV) is independently associated with higher cardiovascular risks. However, whether BPV is associated with poor outcomes for coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) remained undetermined. We aimed to investigate the relationship between BPV and the outcomes of CAD patients undergoing PCI.
