Objectives: Ankle brachial pressure index (ABPI) is limited for diabetic patients. This can have costly impacts upon patient's quality of life along with healthcare budgets, with diabetic care equating to approximately 10% of NHS expenditure.11 We aimed to determine whether ultrasound waveform parameters are an alternative for quantifying lower extremity peripheral arterial disease (PAD) where ABPI is unreliable. Design: This was a prospective, observational study. Waveform parameters, systolic rise time (SRT), maximal systolic acceleration (AccMax) and peak systolic velocity (PSV) were recorded at ankle and compared to the ABPI and an aorta-ankle duplex ultrasound scan (DUS) as gold standard...

The use of intracoronary imaging with intravascular ultrasound (IVUS) or optical coherence tomography (OCT) can define vessel architecture and has an established role in guidance and optimisation of percutaneous coronary intervention. Additionally intracoronary imaging has an emerging role in diagnosis, afforded by the ability to depict vessel wall characteristics not seen on angiography alone. Use of intracoronary imaging is recommended by international consensus guidelines from the European Society of Cardiology and two recent expert consensus position statements from the European Association of Percutaneous Coronary Interventions (EAPCI)...

Background: Susceptibility to and severity of COVID-19 is associated with risk factors for and presence of cardiovascular disease. Methods: We performed a 2-sample Mendelian randomization to determine whether blood pressure (BP), body mass index (BMI), presence of type 2 diabetes (T2DM) and coronary artery disease (CAD) are causally related to presentation with severe COVID-19. Variant-exposure instrumental variable associations were determined from most recently published genome-wide association and meta-analysis studies (GWAS) with publicly available summary-level GWAS data...

Purpose: Coagulation-fibrinolysis markers are widely used for the diagnosis of Stanford type A acute aortic dissection (SAAAD). However, the role of these markers in estimating prognosis remains unclear. Methods: A single-center retrospective study was conducted to identify the relationship between preoperative D-dimer and fibrinogen levels on SAAAD postoperative early prognosis. Results: Of 238 SAAAD patients who underwent surgery between January 2012 and December 2018, 201 (84...

The practice of interventional cardiology has changed dramatically over the last four decades since Andreas Gruentzig carried out the first balloon angioplasty. The obvious technological improvements in stent design and interventional techniques have facilitated the routine treatment of a higher risk cohort of patients, including those with complex coronary artery disease and poor left ventricular function, and more often in the setting of cardiogenic shock (CS) complicating acute myocardial infarction (AMI)...

Objectives: We aimed to assess associations between depressive symptoms, lifestyle, and somatic symptoms during the COVID-19 pandemic. Design: A prospective, observational study using a self-designed questionnaire. Setting: Three general practitioners' (GP) offices in rural Germany. Participants: 271 adult patients without manifest cardiovascular or pulmonary disease with (n = 82) and without (n = 189) hypertension reporting to our GP offices...

Previous studies have found critically ill patients with COVID-19 to have an increased risk of thromboembolic complications. In this case report of two patients admitted with symptomatic COVID-19, both patients developed pulmonary embolism within a few days after hospital discharge. Both patients received thromboprophylaxis and had an increasing fibrin D-dimer during their hospital stay. Continued thromboprophylaxis after hospital discharge may be indicated for patients with COVID-19, especially for patients at high risk of thrombosis with elevated levels of fibrin D-dimer...

Background: The European Society of Cardiology (ESC) published an updated stable chest pain guideline in 2019, recommending the use of an updated pre-test probability (PTP) risk score (RS) to assess the likelihood of coronary artery disease (CAD). We sought to compare the 2019 and 2013 PTPRS in a contemporary cohort of patients. Methods: 612 patients who were investigated with computed tomography coronary angiography (CTCA) for stable chest pain were included in a retrospective analysis...

Objective: To compare statin prescribing rates between intermediate-risk people living with human immunodeficiency virus (HIV; PLWH) and intermediate-risk patients without a diagnosis of HIV for primary prevention of atherosclerotic cardiovascular disease (ASCVD). Methods: Retrospective cohort study . Electronic health record data were used to identify a cohort of PLWH aged 40-75 years with a calculated 10-year ASCVD risk between 7.5%-19.9% as determined by the Pooled Cohort Equation (PCE)...

An 86-year-old woman was admitted for a ruptured popliteal artery aneurysm (rPAA, 26 × 28 mm). Due to the patient's age and comorbidities, emergency endovascular repair was performed. After the failed antegrade guidewire crossing, a retrograde approach from the anterior tibial artery and snaring was performed for lesion crossing, and stentgraft (5 × 50 mm) was deployed from antegrade fashion. At the 14-month follow-up, computed tomography angiogram demonstrated stentgraft patency and reduced aneurysmal size...

Objectives: Postoperative pleural effusion (PE) is common after pediatric cardiac surgery, and if prolonged can lead to the deterioration of the general condition due to malnutrition and result in death. This study aims at identifying the prognostic factors of prolonged PE after pediatric cardiac surgery. Design and settings: Patients were divided into the effective (with chest tube removal within 10 days after medical therapy) and ineffective (with chest tube in place for more than 10 days) groups...

The electrocardiogram (ECG) is a commonly used clinical tool that reflects cardiac excitability and disease. Many parameters are can be measured and with the improvement of methodology can now be quantified in an automated fashion, with accuracy and at scale. Furthermore, these measurements can be heritable and thus genome wide association studies inform the underpinning biological mechanisms. In this review we describe how we have used the resources in UK Biobank to undertake such work. In particular, we focus on a substudy uniquely describing the response to exercise performed at scale with accompanying genetic information...

Background: In FEVAR, visceral stents provide continuity and maintain perfusion between the main body of the stent and the respective visceral artery. The aim of this study was to characterise the incidence and mode of visceral stent failure (type Ic endoleak, type IIIa endoleak, stenosis/kink, fracture, crush and occlusion) after FEVAR in a large cohort of patients at a high-volume centre. Methods: A retrospective review of visceral stents placed during FEVAR over 15 years (February 2003-December 2018) was performed...

Objectives: The right ventricular (RV) function is an important prognostic factor in acute and chronic heart failure (HF). Echocardiography is an essential imaging modality with established parameters for RV function which are useful and easy to perform. However, these fail to reflect global RV volumes due to reliability on one acoustic window. It is therefore attractive to calculate RV volumes and ejection fraction (RVEF/E) using an ellipsoid geometric model which has been validated against MRI in healthy adults but not in the HF patients...

BACKGROUND: Stress from obstructive sleep apnoea (OSA) stimulates catecholamine release and consequently can exacerbate hypertension, even in the absence of a catecholamine-producing tumour (phaeochromocytoma). As such, a positive screening test for suspected phaeochromocytoma may be misleading. There exists only a handful case reports, and no controlled trials, how continuous positive airway pressure (CPAP) to treat OSA influences catecholamine levels. We examined changes to levels of urinary catecholamine and blood pressure in response to CPAP treatment...

Background: It is well-documented that women tend to be worse off post-stroke. They are often frailer, have less independence, lower functionality, increased rates of depression, and overall a lower quality of life. People who have had strokes benefit from rehabilitative support to increase their independence and reduce the risk of stroke reoccurrence. Despite the gender differences in the effects of stroke, interventions explicitly aimed at helping women have not been identified. Purpose: This systematic review aimed to summarize the effectiveness of the health promoting behavioural interventions for reducing risk factors and improved self-management in women post-stroke, compared to usual care...

Objective: The aim of this online clinical vignette-based survey study was to compare risk assessments by vascular surgeons, anaesthesiologists and interventional radiologists involved in treating patients with aortic aneurysms in the Netherlands with the NSQIP risk calculator outcomes. Methods: Participants, recruited using purposive sampling, provided their estimation of the likelihood of postoperative complications and events following aortic surgery in five fictional cases...

OBJECTIVES: There is a high rate of false-positive arterial Thoracic Outlet Syndrome (ATOS) diagnoses due to limited research into the optimal use of ultrasound. To improve future diagnostic efficiency, we aimed to characterise the haemodynamic effects of different provocative positions and estimate the prevalence of compression in the healthy population. DESIGN: In this cross-sectional, observational study, the effect of varying degrees of arm abduction on discomfort levels and/or changes in subclavian artery Doppler waveform was analysed in the healthy population; the peak systolic velocity (PSV), systolic rise time (SRT), phasicity and extent of turbulence were recorded...

Objectives: Following surgical creation of arterio-venous fistulae (AVF), the desired outward remodeling is often accompanied by the development of neointimal hyperplasia (NIH), which can stymie maturation and may lead to thrombosis and access failure. The aim of this study was to investigate the feasibility of using a non-invasive test, to detect and quantify the turbulent flow patterns believed to be associated with NIH development. Design: This was a prospective, observational study...

Background: Smoking and dyslipidaemia are known individual risk factors of coronary artery disease (CAD). The present study examined the combined risk of smoking and dyslipidaemia on coronary atherosclerosis. Methods: Coronary artery calcium (CAC), measured by cardiac CT, was used to assess the extent of CAD, which was related to smoking and dyslipidaemia using logistic regression, adjusted for age, sex, hypertension, BMI and family history of ischaemic heart disease...
