The prevalence of patent foramen ovale (PFO) is higher in patients who have experienced a cryptogenic ischemic stroke. Recent trials have demonstrated the efficacy of PFO closure in preventing recurrent cerebrovascular events. This study evaluated the clinical outcomes of percutaneous PFO closure at a tertiary center in Northern Taiwan.

The aim of this study was to investigate the consistency of diastolic hyperemia-free ratio (DFR) and instantaneous wave-free ratio (iFR) before and after lesions in the distal coronary artery.

To evaluate the feasibility, safety, and effectiveness of the TAI QING single-hub occluder for patent foramen ovale (PFO) in preclinical animal experiments.

Cardiovascular disease, particularly ST-segment elevation myocardial infarction (STEMI), continues to be a leading cause of death worldwide despite advances in treatment options. Contrast-induced nephropathy (CIN) increases the risk of morbidity and mortality after percutaneous coronary intervention (PCI) in STEMI patients. Blood pressure variability (BPV), defined as fluctuations in blood pressure (BP) over time, has been associated with cardiovascular events, stroke, target organ damage and renal dysfunction independently of BP levels. The relationship between BPV and CIN is unknown.

Myocardial ischemia can cause repolarization heterogeneity, manifesting as variations in QT interval; we hypothesized that repolarization heterogeneity could help identify patients with coronary artery disease (CAD). We tested this hypothesis by measuring repolarization heterogeneity with a newly developed multielectrode electrocardiogram (MECG) system, which uses 28 electrodes to increase the spatial resolution of body surface electrical activity.

Various factors associated with cardiopulmonary bypass (CPB) can produce an inflammatory response, resulting in morbidity and mortality. The aim of this study was to investigate how adenosine deaminase (ADA) activity changes after surgery in relation to the emergence of CPB-related complications.

Obesity is a major risk factor for atrial fibrillation (AF). Individuals with obesity can be further classified into metabolically unhealthy obesity (MUO) or healthy obesity (MHO) groups based on the metabolic health subtype. The influence of these phenotypes and overweight status on AF ablation outcomes remains unclear.

Thyroid storm represents a critical and potentially life-threatening complication of thyrotoxicosis. Despite modern critical care, it has a high mortality rate and often requires admission to the intensive care unit (ICU) and the application of extracorporeal membrane oxygenation (ECMO). This study aimed to investigate the outcomes of thyroid storm patients requiring ECMO in a Taiwanese ICU setting.

The efficacy, safety, and clinical outcomes in patients switching to generic rosuvastatin compared to those taking other brand-name atorvastatin are unclear.

The uric acid-to-high-density lipoprotein cholesterol ratio (UHR) has been associated with both the functional and anatomical significance of coronary lesions. This study aimed to investigate the relationship between UHR and the severity of coronary artery disease (CAD) in patients with non-ST-elevation myocardial infarction (NSTEMI), as evaluated using the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score.
