AIM: The 2023 ESC guidelines for acute coronary syndrome note that contemporary data are heterogenous regarding beta-blockers (BB) use post-myocardial infarction (MI) in patients without reduced ejection fraction (EF) or heart failure (HF). We aimed to address the heterogeneity in contemporary data around BB post-MI in this population. METHODS: We searched 6 databases from Jan 1, 2000 to Sep 1, 2024 to identify contemporary studies enrolling MI patients without reduced EF (≤40%) or history of HF receiving BB at index MI, and comparing outcomes between BB users and non-users...

Heart Rhythm management is a continuously evolving sub-speciality of cardiology. Every year, many physicians and allied professionals start and complete their training in Cardiac Implantable Electronic Devices (CIED) or Electrophysiology (EP) across the EHRA member countries. While this training ideally ends with an EHRA certification, the description of the learning pathway (what, how, when and where) through an EHRA Core Curriculum is also a prerequisite for a successful training. The first EHRA core curriculum for physicians was published in 2009...

BACKGROUND: Patients undergoing transcatheter aortic valve implantation (TAVI) for bicuspid aortic stenosis (AS) frequently present with ascending aortic (AAo) dilatation which is left untreated. The objective of this study was to study the natural progression and underlying mechanisms of AAo dilatation after TAVI for bicuspid AS. METHODS: Patients with a native bicuspid AS and a baseline AAo maximum diameter > 40 mm treated by TAVI and in whom post-TAVI computed tomography (CT) scans beyond 1 year were available were included...

BACKGROUND AND AIMS: The role of biomarkers in diagnosing pulmonary hypertension (PH) and distinguishing between pre- and post-capillary PH remains poorly understood. We aimed to identify biomarkers with a strong association with mean pulmonary arterial pressure, mPAP (PH diagnosis) and pulmonary vascular resistance, PVR (pre-capillary component), but not with pulmonary arterial wedge pressure, PAWP (post-capillary component). METHODS: Blood samples were collected in patients undergoing right heart catheterization within a prospective cross-sectional study...

BACKGROUND: Ferritin is commonly used to evaluate iron stores and guide therapeutic decisions regarding intravenous iron supplementation. However, in the context of AHF, inflammation-driven upregulation of ferritin might disrupt its correlation with iron stores, restricting iron bioavailability and potentially amplifying the inflammatory response. AIM: This study aims to assess the clinical and prognostic associations of ferritin levels in an AHF cohort and to determine whether the prognostic value of ferritin is influenced by the presence of infection, inflammatory activation, and other markers of iron deficiency...

BACKGROUND: Empagliflozin administered after acute myocardial infarction proofed to improve cardiometabolic parameters and biomarkers, but the impact on cardiac function is still largely unknown. The aim of this post-hoc echocardiographic sub-analysis of the EMMY trial was to provide in-depth echocardiographic analysis on the effects of empagliflozin versus placebo on standard and novel echocardiographic structural and functional parameters after acute myocardial infarction. METHODS: In this post-hoc analysis of the EMMY trial a subset of 313 patients (157 empagliflozin vs...

BACKGROUND AND AIMS: Currently, the influence of metabolic syndrome (Mets) on the plaque characteristics and prognosis of patients with acute coronary syndrome (ACS) is poorly understood. Thus, the study aimed to characterize the pancoronay plaques of ACS patients with Mets using optical coherence tomography (OCT) and to evaluate the cohort's prognosis. METHODS: Between February 2015 and September 2020, 745 ACS patients who underwent OCT imaging of the three coronary arteries were included, divided into Mets (n = 252) and non-Mets (n = 493) groups...

BACKGROUND: Left ventricular thrombus (LVT) is associated with high rates of systemic embolism. Vitamin K antagonists (VKAs) are the only approved treatment for LVT. Although evidence suggests direct oral anticoagulant (DOACs) to be at least equally effective in general, the efficacy of individual DOACs remains unclear. METHODS: A literature search was performed in EMBASE, MEDLINE and Web of Science looking for randomized controlled trials (RCTs) and non-randomized controlled studies of interventions (NRSI) comparing individual DOACs to VKAs for the treatment of LVT...

Blood pressure (BP) variability (BPV) is associated with an increased risk of cardiovascular events, independent of absolute BP values. However, the predictive significance of very short-term BPV, occurring within seconds or minutes, in patients with ischemic heart disease (IHD) has yet to be established. This prospective study involved 206 consecutive hospitalized patients with IHD (mean age 67.6 years, 78.2% male) who underwent pulse transit time (PTT)-based continuous BP recording during the night-time...

The US dietary supplement (DS) market has expanded exponentially since 1994, with an estimated 50,000-80,000 individual products currently available. Many DS claim cholesterol or cardiovascular benefits. Overall, well-designed randomized controlled trials (RCTs) with DS are lacking, while studies with favorable results are commonly performed outside of the USA, resulting in inconsistent findings. The expansion of the DS market has limited the ability of the Food and Drug Administration to regulate and prevent substandard products...

BACKGROUND: Aromatase inhibitors (AIs) are the standard therapeutic approach for hormone receptor-positive postmenopausal breast cancer. However, there are concerns about increased cardiovascular risk due to their antioestrogenic effects. This study aimed to investigate the potential association between duration of AI treatment and the severity of coronary artery calcification (CAC). METHODS: The study included outpatients who initiated adjuvant endocrine therapy with AIs for breast cancer from August 2010 to October 2022...

BACKGROUND: Exposure to metals, a newly recognized risk factor for cardiovascular disease (CVD), could be related to atherosclerosis progression. OBJECTIVES: The authors hypothesized that higher urinary levels of nonessential (cadmium, tungsten, uranium) and essential (cobalt, copper, zinc) metals previously associated with CVD would be associated with baseline and rate of change of coronary artery calcium (CAC) progression, a subclinical marker of CVD in MESA (Multi-Ethnic Study of Atherosclerosis)...

OBJECTIVE: According to the World Health Organization, 17.9 million individuals died from cardiovascular diseases (CVD) in 2019, constituting 32% of all global mortalities. In recent years, percutaneous coronary interventions such as stenting have become a common treatment approach for coronary artery disease (CAD). However, the problem of angina recurrence after stenting, associated with in-stent restenosis, persists. The aim of this study was to elucidate the intricate structure of relevant countries and regions, prominent research institutions, prolific authors, and recurring keywords shaping the landscape of this field...

Calcific aortic valve disease (CAVD), a nonrheumatic stenosis of the trileaflet aortic valve, is a complex, multifaceted cardiovascular condition involving a widespread inflammatory process and an analogous atheromatous process affecting the arteries. It is currently the most encountered valvular abnormality in cardiology. Although distinctive abnormal mechanical forces are at the core propelling a responsive mechanosensitive feedback cascade, implicated in both initiation and perpetuation of CAVD; we propose a conundrum of metabolic abnormalities including hypertension, elevated fasting blood sugar, decreased high-density lipoprotein, hypertriglyceridemia, and abdominal obesity as perpetuators of this process...

People who experience out-of-hospital cardiac arrest often require care at a regional center for continued treatment after resuscitation, but many do not initially present to the hospital where they will be admitted. For patients who require interfacility transport after cardiac arrest, the decision to transfer between centers is complex and often based on individual clinical characteristics, resources at the presenting hospital, and available transport resources. Once the decision has been made to transfer a patient after cardiac arrest, there is little direct guidance on how best to provide interfacility transport...

BACKGROUND: Analysis of prescription patterns and lipid profiles can play a crucial role in rational drug use and patient safety. This study aimed to analyze the prescription pattern and impact of statin in lipid profile among ischemic heart disease (IHD) patients. MATERIALS AND METHODS: A prospective observational study was conducted for 7 months in the cardiology department. IHD patients above 18 years and undergoing statin therapy for at least 3 months were enrolled...

BACKGROUND: Nicorandil and verapamil can improve coronary blood flow and coronary microcirculation during percutaneous coronary intervention. However, the effects of intracoronary (IC) administration of nicorandil and verapamil on hemodynamics remain unclear. AIMS: To clarify the safety and effects of IC administration of nicorandil and verapamil on blood pressure (BP) and heart rate (HR) to provide evidence-based basis for clinical intervention. METHODS: The study cohort included 70 patients with coronary artery stenosis recruited from Zhejiang Provincial Hospital of Traditional Chinese Medicine...
