Takotsubo syndrome (TTS) is a transient left ventricle dysfunction usually caused by a stressful trigger (emotional or physical). We report the case of a 77 year-old female patient who presented with TTS caused by a pheochromocytoma, a catecholamine-producing neuroendocrine tumour. Diagnosis was facilitated by acute kidney injury prompting renal ultrasound, recurrence of TTS and symptoms of episodic palpitations, profuse sweating and labile blood pressure. Furthermore, during her hospitalisation the patient also developed an Ogilvie syndrome, an acute colonic pseudo-obstruction, due to the catecholamine-excess...

BACKGROUND: The resting full-cycle ratio (RFR), a new non-congestive resting index, is commonly used for physiological evaluations of coronary arteries. AIMS: This study aims to evaluate the accuracy of RFR in detecting coronary artery stenosis with hemodynamic significance using fractional flow reserve (FFR) as the reference standard. METHODS: Using 'RFR, resting full-cycle ratio' as the search term, we searched PubMed, Embase, Cochrane Library, and Web of Science databases, screening the literature according to the inclusion and exclusion criteria...

OBJECTIVE: To systematically evaluate the diagnostic value of growth differentiation factor-15 (GDF-15) for heart failure with preserved ejection fraction (HFpEF). METHODS: Chinese and English literature on the diagnosis of HFpEF using GDF-15 were searched in PubMed, Embase, Web of Science (WOS), Cochrane Library, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database, WanFang Database, and others. The literature on the diagnostic value of the GDF-15 test for HFpEF was screened from the establishment of the database to April 2023 according to the inclusion and exclusion criteria...

BACKGROUND: Heart failure (HF) is a global growing health threat. This case-control clinical trial aimed to detect the predictive value and difference in aldosterone level between right side heart failure, heart failure with decreased ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpEF) and compare the efficacy and safety of adding mineralocorticoid receptor antagonist (MRA) for treatment. PATIENTS AND METHODS: We recruited 151 participants, 135 HF patients divided equally into 45 patients in each group:(1) right side HF (2) HFrEF and (3) HFpEF and 16 healthy controls...

INTRODUCTION: Hypertrophic cardiomyopathy(HCM) is a genetic cardiomyopathy with a prevalence of 1/500 and causes adverse outcomes, usually due to left ventricular outflow tract obstruction. AIM: In this study, we aimed to determine the possible differences and predictors of obstructive hypertrophic cardiomyopathy HCM (Obs-HCM) and nonobstructive HCM (Nonobs-HCM) by electrocardiographic (ECG) and echocardiographic (ECHO) evaluations with clinical, demographic, and biochemical characteristics...

BACKGROUND: This study aimed to report the genotypes and phenotypes of hereditary transthyretin cardiac amyloidosis (hATTR-CA) in a Western Chinese cohort and review the genetic profiles of this disorder in the Chinese population. METHODS: Transthyretin ( TTR ) gene sequencing of probands diagnosed with TTR cardiac amyloidosis and their relatives was performed at West China Hospital of Sichuan University from January 2018 to December 2021. All patients underwent endomyocardial biopsy for light and electron microscopy examinations...

Background: In 2019, the European Atherosclerosis Society (EAS) published updated guidelines, recommending even lower blood cholesterol targets than previously. In patients with familial hypercholesterolaemia (FH), who have very elevated blood cholesterol levels and are at ('Very') 'High risk' of atherosclerotic cardiovascular disease (ASCVD), this represents a real challenge. Anti-Proprotein convertase subtilisin/kexin type 9 monoclonal antibody (anti-PCSK9 mAb) has been commercially available for FH in Belgium since 2015...

BACKGROUND: Evidence suggests patients undergoing Primary Percutaneous Coronary Intervention (PPCI) who have a prior history of Coronary Artery Bypass Grafting (CABG) are more likely to experience adverse cardiac events compared to patients without prior CABG. We aimed to study risk factors of one-year Major Adverse Cardiovascular Events (MACE) in patients undergoing PPCI with a prior history of CABG. METHODS: Patients with a history of CABG undergoing PPCI on Saphenous Vein Graft (SVG) were contacted one year after PPCI...

OBJECTIVES: Insulin resistance (IR) is associated with an increased risk of adverse cardiovascular outcomes. The triglyceride-glucose index (TyG index) is a reliable marker of IR. No study has examined the impact of the TyG index on major adverse cardiac and cerebrovascular events (MACCEs) in RTRs. Therefore, this study aimed to investigate the predictive value of the TyG index for MACCEs in RTRs. MATERIALS AND METHODS: Non-diabetic patients undergoing renal transplantation were retrospectively enrolled...
