High on-aspirin treatment platelet reactivity and restenosis after percutaneous coronary intervention: results of the Intracoronary Stenting and Antithrombotic Regimen-ASpirin and Platelet Inhibition (ISAR-ASPI) Registry.

Objective: The aim of this study was to assess the association between high on-aspirin treatment platelet reactivity (HAPR) and the subsequent risk of restenosis after percutaneous coronary intervention (PCI) with predominantly drug-eluting stents.

Background: The association between HAPR and subsequent risk of restenosis after PCI is unclear.

Methods: This study included 4839 patients undergoing PCI (02/2007-12/2011) in the setting of the Intracoronary Stenting and Antithrombotic Regimen-ASpirin and Platelet Inhibition (ISAR-ASPI) registry.

One-Year Ischemic and Bleeding Events According to Renal Function in Patients With Non-ST-Segment Elevation Acute Coronary Syndromes Treated With Percutaneous Coronary Intervention and Third-Generation Antiplatelet Drugs.

The optimal antiplatelet therapy of patients with non-ST-segment elevation acute coronary syndromes (NSTE-ACS) and chronic kidney disease (CKD) remains unknown. This study included 2,364 patients with NSTE-ACS undergoing predominantly percutaneous coronary intervention (PCI), who were randomized to ticagrelor or prasugrel in the ISAR-REACT 5 trial. Estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation.

Ten-year patterns of stent thrombosis after percutaneous coronary intervention with new- versus early-generation drug-eluting stents: insights from the DECADE cooperation.

Introduction And Objectives: The DECADE cooperation is a pooled analysis of individual patient data from drug-eluting stent (DES) trials with a 10-year follow-up. This analysis reports the risk of definite stent thrombosis (ST) through to 10 years after percutaneous coronary intervention (PCI) in patients treated with early- and new-generation DES.

Methods: Individual patient data from 5 DES trials with a 10-year follow-up were pooled.

Body mass index and efficacy and safety of ticagrelor versus prasugrel in patients with acute coronary syndromes.

Introduction And Objectives: The efficacy and safety of ticagrelor vs prasugrel in patients with acute coronary syndromes (ACS) according to body mass index (BMI) remain unstudied. We assessed the efficacy and safety of ticagrelor vs prasugrel in patients with ACS according to BMI.

Methods: Patients (n=3987) were grouped into 3 categories: normal weight (BMI <25kg/m; n=1084), overweight (BMI ≥ 25 to <30kg/m; n=1890), and obesity (BMI ≥ 30kg/m; n=1013).

COVID-19-associated myocarditis presenting as new-onset heart failure and atrial fibrillation.

A 58-year-old man presented to the emergency department with recent-onset palpitations and progressive exertional dyspnoea. ECG demonstrated new-onset atrial fibrillation. Transthoracic echocardiogram showed global impairment in left ventricular systolic function with left ventricular ejection fraction of 20%.

Real World Prescribing Strategies for Patients With an Indication for Oral Anticoagulation Undergoing Percutaneous Coronary Intervention.

Background: Limited data are available regarding real-world prescribing in patients with an indication for oral anticoagulation (OAT) who undergo percutaneous coronary intervention (PCI). Most current guidelines recommend a period of triple therapy with OAT and dual antiplatelet (DAPT) agents over dual therapy with an OAT and DAPT but the clinical benefit is still unclear giving rise to limited evidence-based recommendations.

Aim: To analyze the appropriateness of OAT and anti-platelet strategies post PCI in a real-world cohort of patients in 2 academic teaching hospitals.

Cardiac amyloidosis presenting with recurrent ischaemic strokes.

A 72-year-old man presented to our service with sudden onset right-sided weakness, aphasia and gaze palsy with diplopia. CT angiogram demonstrated an acute thrombotic occlusion of the distal basilar artery, a basilar infarct and the patient underwent successful thrombectomy. ECG and telemetry demonstrated slow atrial fibrillation (AF).

Performing diagnostic radial access coronary angiography on uninterrupted direct oral anticoagulant therapy: a prospective analysis.

Purpose: We sought to assess the safety of performing diagnostic radial access coronary angiography with uninterrupted anticoagulation on patients receiving direct oral anticoagulant therapy.

Background: Direct oral anticoagulants have become a popular choice for the prevention of thromboembolism. Risk factors for thromboembolism are common among cardiovascular conditions and indications for direct oral anticoagulant therapy as well as coronary angiography often overlap in patients.

Assessing suitability for sacubitril-valsartan therapy in an Irish cohort: challenges and opportunities.

Introduction: Sacubitril-valsartan has been shown by the PARADIGM-HF trial to decrease hospital admissions and improve mortality in patients with heart failure with reduced ejection fraction. The PARADIGM trial had stringent exclusion criteria. It is not known how applicable these trial criteria are to real-life practice.

Left distal trans-radial access facilitates earlier discharge post-coronary angiography.

Aims: In 2017, Kiemeneij published a paper on distal trans-radial artery access for coronary angiography in 62 patients. This paper proposed several advantages to this method. Since this paper was published, several other papers have been published describing this technique, with less than 200 cases in total described.

Circadian and seasonal variations in patients with acute STEMI: A retrospective, single PPCI center study.

This was a retrospective observational analysis of all (n = 876) ST-segment elevation myocardial infarction (STEMI) patients treated with primary percutaneous coronary intervention (PPCI) at University Hospital Limerick (UHL) from 2012 to 2016 to determine whether chronological patterns existed in incidence and mortality at our center. Data were obtained from the electronic Cardiology STEMI database in UHL. Statistical analysis was performed using the Independent Samples t Test, ANOVA and Pearson's Chi-Squared test.

Atrial myxoma presenting as infective endocarditis.

A 23-year-old Asian student presented to our service with a 1-month history of fever, weight loss of 10 kg, night sweats, fatigue and general malaise. He was previously well with no significant medical or family history. He had a low-grade pyrexia and cardiac auscultation revealed a diastolic murmur consistent with 'tumour plop'.

Eosinophilic myocarditis: an often subtle and potentially under-recognised phenomenon.

A 34-year-old woman presented to our service with chest pain, a troponin rise and dynamic ECG changes. Of note, she had complained of fatigue, feeling constitutionally unwell and a generalised rash in the days prior to her presentation. Her echocardiogram showed normal wall motion and preserved ejection fraction.
