Background: This retrospective propensity-matched study investigated the impact of prior percutaneous coronary intervention (PCI) on short-term and long-term survival after coronary artery bypass graft surgery (CABG).

Methods: A total of 4,634 patients underwent isolated first-time CABG between April 2004 and March 2014. Among these, 424 (9.

The decision-making process in the management of patients with ischaemic heart disease has historically been the responsibility of the cardiologist and encompasses medical management, percutaneous coronary intervention (PCI) or coronary artery bypass surgery (CABG). Currently, there is significant geographical variability in the PCI:CABG ratio. There are now emerging recommendations that this decision-making process should be carried out through a multidisciplinary approach, namely the Heart Team.

Objective: We evaluated differences in clinical outcomes between patients who underwent final kissing balloon inflation (FKBI) and patients who did not undergo FKBI in bifurcation treatment using the Tryton Side Branch Stent (Tryton Medical, Durham, North Carolina, USA).

Methods: Clinical outcomes were defined as target vessel failure (composite of cardiac death, any myocardial infarction and clinically indicated target vessel revascularisation), cardiac death, myocardial infarction (MI), clinically indicated target vessel revascularisation and stent thrombosis. Cumulative event rates were estimated using the Kaplan-Meier method.

Aims: Smaller studies have previously shown promising results after Tryton Side Branch Stent™ (Tryton Medical, Durham, NC, USA) placement. However, these previous studies were limited by their small sample size and relatively short follow-up. We performed a patient-level pooled analysis to evaluate six-month and one year clinical outcomes of more than 900 patients who were enrolled in eight registries with the Tryton stent.

Recent ESC/EACTS revascularization guidelines advocate a 'Heart Team' (HT) approach in the decision-making process when managing patients with coronary disease. We prospectively assessed HT decision-making in 150 patients analysing personnel attendance, data presented, the 'actioning' of the HT decision and, if not completed, then the reasons why. Additionally, 50 patients were specifically re-discussed after 1 year in order to assess consistency in decision-making.

Aims: Revascularization is frequently advocated to improve ventricular function and prognosis for patients with heart failure due to coronary artery disease, especially when there is evidence of extensive myocardial viability.

Methods And Results: Patients with heart failure, coronary artery disease, and a left ventricular (LV) ejection fraction < 35%, who had a substantial volume of viable myocardium with contractile dysfunction assessed by any standard imaging technique, were randomly assigned to a strategy of conservative management vs. angiography with the intent of percutaneous or surgical revascularization.

Cardiogenic shock is the commonest cause of death in acute myocardial infarction (AMI). Although the syndrome of cardiogenic shock complicating AMI is common to all, the spectrum of underlying pathology is broad. While thrombolysis can be attempted with inotropic support or augmentation of blood pressure with an intra-aortic balloon pump, the greatest mortality benefit is seen after urgent coronary angiography and early revascularization.

No-reflow phenomenon, defined as inadequate myocardial perfusion of the adequately dilated target vessel without evidence of angiographic mechanical obstruction. It is a multifactorial, well-recognised, secondary phenomenon following reperfusion therapy such as thrombolysis or percutaneous coronary interventions (PCI). The pathophysiological mechanisms leading to the no-reflow state are incompletely understood.

Cardiac conditions account for at least half of acute medical admissions. The provision of a comprehensive and responsive cardiological service in the UK is therefore pivotal to the manner in which the NHS continues to modernise. This article reviews recent developments in cardiology, describes the current provision of cardiac services for the more commonly encountered conditions, and explores future developments that will impact on the care patients presenting with heart disease receive.
