BACKGROUND: Detection of atrial fibrillation (AF) in patients who had ischaemic stroke and transient ischaemic attack (IS/TIA) is recommended. We aimed to compare external loop recording (ELR) against simultaneous continuous ECG recording for AF detection in patients who had acute IS/TIA and determine sensitivity, specificity and positive predictive value of AF detection using ELR. We hypothesised ELR to detect 15% fewer patients with AF than continuous ECG recording. METHODS: In this prospective cohort study, we included 1412 patients who had acute IS/TIA without prior AF...

AIM: To examine the effect of endothelial shear stress (ESS) on the dynamic changes in plaque phenotype. METHODS: Patients with myocardial infarction that had intravascular ultrasound-virtual histology (IVUS-VH) and optical coherence tomography (OCT) at baseline and 13-month follow-up were studied. The IVUS-VH data were used to reconstruct the nonculprit vessels, and in the obtained models the ESS was estimated in 3 mm segments. Plaque morphology was derived in each segment from IVUS-VH and OCT...

OBJECTIVE: To investigate whether regular blood donation decreases cardiovascular risk. METHODS: All 159 934 Dutch whole-blood donors with an active donation career of at least 10 years were categorised into sex-specific donation tertiles based on the number of donations during this 10-year qualification period. Cardiovascular endpoints were based on hospital discharge diagnoses and death certificates from Dutch Hospital Data and Statistics Netherlands and occurring after the 10-year qualification period...

This review provides a comprehensive overview of the available data on antithrombotic therapy after transcatheter aortic valve implantation (TAVI). In the absence of large randomised clinical trials, clinical practice is leaning towards evidence reported in other populations. Due to the greater risk of major bleeding associated with oral anticoagulation using a vitamin-K antagonist (VKA), antiplatelet therapy (APT) may be considered as the first-line treatment of patients undergoing TAVI. Overall, single rather than dual APT is preferred...

BACKGROUND: To evaluate the effects of proprotein convertase subtilisin/kexin 9 (PCSK9) inhibitors on major adverse cardiovascular events (MACE). METHODS: Our systematic review included randomised controlled trials if they studied PCSK9 inhibitors in patients for primary and/or secondary prevention of cardiovascular diseases or with hypercholesterolaemia/hyperlipidaemia. Dichotomous variables from individual studies were pooled by relative risks (RR) and their 95% CIs using the random-effect model...

OBJECTIVES: Congestion is associated with worse outcomes in critically ill surgical patients but can be difficult to quantify noninvasively. We hypothesised that plasma volume status (PVS), estimated preoperatively using a validated formula that enumerates percentage change from ideal plasma volume (PV), would provide incremental prognostic utility after coronary artery bypass graft (CABG) surgery. METHODS: In this retrospective cohort study, patients who underwent CABG surgery (1999-2010) were identified from a prospectively collected database...

BACKGROUND: Fenestration in the Fontan circulation potentially liberates patients from factors leading to cardiovascular remodelling, through stable haemodynamics with attenuated venous congestion. We hypothesised that a fenestrated Fontan procedure would possess chronic haemodynamic advantages beyond the preload preservation. METHODS: We enrolled 35 patients with fenestrated Fontan with a constructed pressure-volume relationship under dobutamine (DOB) infusion and/or transient fenestration occlusion (TFO)...

The diagnosis of acute mitral regurgitation (MR) is often missed or delayed because the clinical presentation is substantially different from that in patients with chronic MR. Management of acute MR depends on the specific aetiology of valve dysfunction and there is a lack of consensus on the optimal therapeutic approach in many patients. In particular, management of secondary MR due to acute ischaemia is challenging because of unique mechanisms of valve incompetence compared with chronic ischaemic MR. Another clinical challenge is management of acute MR due to transient systolic anterior motion of the mitral valve in the acute phase of Takotsubo cardiomyopathy, which commonly resolves within a few weeks...

CLINICAL INTRODUCTION: A 42 year-old man with hypertension, hyperlipidaemia and tobacco abuse presented with typical chest pain. The pain was located in the substernal area, described as squeezing, non-radiating and awoke him from sleep. The pain was not associated with shortness of breath, abdominal pain, nausea and diaphoresis. On physical examination, blood pressure was 171/115 mm Hg, heart rate was 60 beats/min, heart sounds were normal without murmur, lung fields were clear and there was no peripheral oedema...

OBJECTIVE: To describe the prevalence and incidence of cardiovascular risk factors, established cardiovascular disease (CVD) and cardiovascular medication use, among immigrant individuals of diverse national origins living in Catalonia (Spain), a region receiving large groups of immigrants from all around the world, and with universal access to healthcare. METHODS: We conducted a population-based analysis including >6 million adult individuals living in Catalonia, using the local administrative healthcare databases...

OBJECTIVE: To evaluate cardiovascular (CV) outcomes in outpatients with coronary artery disease (CAD) living alone compared with those living with others. METHODS: The prospeCtive observational LongitudinAl RegIstry oF patients with stable coronarY artery disease (CLARIFY) included outpatients with stable CAD. CLARIFY enrolled participants in 45 countries from November 2009 to July 2010, with 5 years of follow-up. Living arrangement was documented at baseline. The primary outcome was a composite of major adverse cardiovascular events (MACEs) defined as CV death, myocardial infarction (MI) and stroke...

INTRODUCTION: Studies on pregnancy risk in women with ischaemic heart disease (IHD) have mainly excluded pregnancies in women with pre-existent IHD. There is a need for better information about the pregnancy risks in these women and their offspring. METHODS: We performed a systematic review searching the PubMed/MEDLINE public database for pregnancy in women with pre-existent IHD analysing the cardiac, obstetric and fetal/neonatal outcome of pregnancy in women with pre-existing IHD...

OBJECTIVE: To describe the epidemiology, long-term outcomes and temporal trends in mortality in ambulatory patients with chronic heart failure (HF) with reduced (HFrEF), mid-range (HFmrEF) or preserved ejection fraction (HFpEF) from three European countries. METHODS: We identified 10 312 patients from the Norwegian HF Registry and the HF registries of the universities of Heidelberg, Germany, and Hull, UK. Patients were classified according to baseline left ventricular ejection fraction (LVEF) and time of enrolment (period 1: 1995-2005 vs period 2: 2006-2015)...

OBJECTIVE: The aim of this study is to evaluate the long-term risk of cardiac death and sudden cardiac death (SCD) and/or sustained ventricular arrhythmias (SVAs) in patients with coronary chronic total occlusions (CTO) revascularised versus those with CTO not revascularised by percutaneous coronary intervention (PCI). METHODS: From a cohort of 1357 CTO-PCI patients, 1162 patients who underwent CTO PCI attempt were included in this long-term analysis: 837 patients were revascularised by PCI (CTO-R group) and 325 were not revascularised (CTO-NR group)...
