Nurse‐led counseling for coronary artery disease patients: A 1‐year follow‐up study
2021
Nurse-led counseling and systematic follow-up has been shown to reduce cardiovascular risk factor levels. The study aim was to investigate if cardiovascular risk factor levels could be reduced in patients with coronary artery disease with a nurse-led intervention and to report patients’ evaluations of nurse-led counseling. The study design was a real-life longitudinal follow-up counseling intervention. Data were collected from November 2017 to May 2020. The nurse-led intervention and patients’ follow-up time was one year. Of the 78 patients recruited, 74 completed the study. The most significant findings were in the levels of total cholesterol, low-density lipoprotein cholesterol and trigly…
Cardiovascular Responses to Muscle Stretching: A Systematic Review and Meta-analysis
2021
AbstractThe aim of this study will be to review the current body of literature to understand the effects of stretching on the responses of the cardiovascular system. A literature search was performed using the following databases: Scopus, NLM Pubmed and ScienceDirect. Studies regarding the effects of stretching on responses of the cardiovascular system were investigated. Outcomes regarded heart rate(HR), blood pressure, pulse wave velocity (PWV of which baPWV for brachial-ankle and cfPWV for carotid-femoral waveforms), heart rate variability and endothelial vascular function. Subsequently, the effects of each outcome were quantitatively synthetized using meta-analytic synthesis with random-…
Proceedings from the European clinical consensus conference for renal denervation: considerations on future clinical trial design: Figure 1
2015
Approximately 8–18% of all patients with high blood pressure (BP) are apparently resistant to drug treatment.1,2 In this situation, new strategies to help reduce BP are urgently needed but the complex pathophysiology of resistant hypertension makes this search difficult. Not surprisingly in this context, the latest non-drug treatment which triggered controversy is catheter-based renal denervation (RDN).3,4 The method uses radiofrequency energy, or alternatively ultrasound or chemical denervation, to disrupt renal nerves within the renal artery wall, thereby reducing sympathetic efferent and sensory afferent signalling to and from the kidneys.5,6 Various experimental models of hypertension s…
Endovascular Aneurysm Repair
2002
Background — The purpose of the present study was to systematically analyze the histopathologic organization processes in excluded aneurysms after endovascular stenting and to develop a noninvasive monitoring method for these processes using MRI. Methods and Results — In 36 mongrel dogs, autologous aortic aneurysms were created. Endovascular treatment was performed using covered stents. Follow-up was after 1 week, 6 weeks, and 6 months. MRI was performed with T 2 -weighted turbo-spin-echo sequences and T 1 -weighted spin-echo sequences and was repeated after contrast bolus with gadolinium. Histopathologic findings were correlated to signal intensities (SIs) of MRI images. SIs of distinct a…
Imaging techniques for the vulnerable coronary plaque
2007
The goal of this article is to illustrate the main invasive and noninvasive diagnostic modalities to image the vulnerable coronary plaque, which is responsible for acute coronary syndrome. The main epidemiologic and histological issues are briefly discussed in order to provide an adequate background. Comprehensive coronary atherosclerosis imaging should involve visualization of the entire coronary artery tree and plaque characterization, including three-dimensional morphology, relationship with the lumen, composition, vascular remodelling and presence of inflammation. No single technique provides such a comprehensive description, and no available modality extensively identifies the vulnerab…
Contemporary practice and technical aspects in coronary intervention with bioresorbable scaffolds : a European perspective
2015
Aims Next to patient characteristics, the lack of a standardised approach for bioresorbable vascular scaffold (BVS) implantation is perceived as a potential explanation for the heterogeneous results reported so far. To provide some guidance, we sought to find a consensus on the best practices for BVS implantation and management across a broad array of patient and lesion scenarios. Methods and results Fourteen European centres with a high volume of BVS procedures combined their efforts in an informal collaboration. To get the most objective snapshot of different practices among the participating centres, a survey with 45 multiple choice questions was prepared and conducted. The results of th…
Coronary artery anomalies: incidence, pathophysiology, clinical relevance and role of diagnostic imaging
2006
Conventional coronary angiography is the gold standard for the diagnosis of coronary artery anomalies. Coronary anomalies are relatively rare findings in patients undergoing conventional coronary angiography for suspected obstructive coronary artery disease. Recently, the increasing performance of diagnostic techniques, such as electron beam tomography (EBT), magnetic resonance (MR) and, more recently, multislice computed tomography (MSCT), has enabled their application to cardiac imaging. MSCT, in particular, has a prominent role in coronary imaging due to its spatial and temporal resolution and three-dimensional capabilities. We report the incidence and pathophysiology of coronary artery …
Methods to investigate coronary microvascular function in clinical practice.
2012
A growing amount of data is increasingly showing the relevance of coronary microvascular dysfunction (CMVD) in several clinical contexts. This article reviews techniques and clinical investigations of the main noninvasive and invasive methods proposed to study coronary microcirculation and to identify CMVD in the presence of normal coronary arteries, also trying to provide indications for their application in clinical practice.
Dietary fiber and health outcomes: an umbrella review of systematic reviews and meta-analyses
2018
Background Several studies have suggested that higher consumption of dietary fiber is beneficial for a variety of health outcomes. However, many results have been inconclusive and, to our knowledge, there has been no attempt to systematically capture the breadth of outcomes associated with dietary fiber intake or to systematically assess the quality and the strength of the evidence on the associations of dietary fiber intake and different health outcomes or medical conditions. Objective The aim of this study was to describe the diverse health outcomes convincingly associated with dietary fiber consumption. Design This was an umbrella review of systematic reviews with meta-analysis of observ…
