Time to ECG diagnosis delays inter-hospital transfer to revascularization in STEMI patients presenting to a regional emergency department: a five-year audit.

Background: Reducing the door-to-balloon time (D2BT) in ST-elevation myocardial infarction (STEMI) patients maximizes myocardial salvage and mitigates morbidity/mortality.

Aims: To assess the D2BT in STEMI patients requiring inter-hospital transfer for revascularization and identify any potential causes of delay.

Methods: Consecutive patients presenting to the Connolly Hospital Blanchardstown (CHB) emergency department (ED) who were transferred to the Mater Misericordiae University Hospital in Dublin for primary percutaneous coronary intervention from January 2018 to October 2022 were identified in a regional database and their D2BTs calculated.

Interhospital and interindividual variability in secondary prevention: a comparison of outpatients with a history of chronic coronary syndrome versus outpatients with a history of acute coronary syndrome (the iASPIRE Study).

Background: Studying variability in the care provided to secondary prevention coronary heart disease (CHD) outpatients can identify interventions to improve their outcomes.

Methods: We studied outpatients who had an index CHD event in the preceding 6-24 months. Eligible CHD events included acute coronary syndrome (ACS) and coronary revascularisation for stable chronic coronary syndrome (CCS).

Study of patients with iron deficiency and HF in Ireland: prevalence and treatment budget impact.

This study aims to present the screening, prevalence and treatment of heart failure (HF) patients with iron deficiency in an Irish hospital and use an economic model to estimate the budget impact of treating eligible patients with intravenous ferric carboxymaltose (IV FCM). Retrospective data were collected on 151 HF patients over a one-year period from all newly referred HF patients to a secondary care hospital. This included 36 patients with preserved ejection fraction (HFpEF) and 115 with reduced ejection fraction (HPrEF).

A first case report of dapsone inducing recurrent ventricular arrhythmia.

Background: Ventricular arrhythmias (VAs) are life-threatening arrhythmias which are associated with significant morbidity and mortality. Ventricular arrhythmias are induced by a change in the myocardial environment altering cardiomyocyte electrophysiology. The substrate for VA includes myocardial scar, electrolyte disturbances, and drugs altering cellular electrophysiology.
