ESC Working Group on Coronary Pathophysiology and Microcirculation position paper on \u27coronary microvascular dysfunction in cardiovascular disease\u27.
Although myocardial ischaemia usually manifests as a consequence of atherosclerosis-dependent obstructive epicardial coronary artery disease, a significant percentage of patients suffer ischaemic events in the absence of epicardial coronary artery obstruction. Experimental and clinical evidence highlight the abnormalities of the coronary microcirculation as a main cause of myocardial ischaemia in patients with \u27normal or near normal\u27 coronary arteries on angiography. Coronary microvascular disturbances have been associated with early stages of atherosclerosis even prior to any angiographic evidence of epicardial coronary stenosis, as well as to other cardiac pathologies such as myocardial hypertrophy and heart failure. The main objectives of the manuscript are (i) to provide updated evidence in our current understanding of the pathophysiological consequences of microvascular dysfunction in the heart; (ii) to report on the current knowledge on the relevance of cardiovascular risk factors and comorbid conditions for microcirculatory dysfunction; and (iii) to evidence the relevance of the clinical consequences of microvascular dysfunction. Highlighting the clinical importance of coronary microvascular dysfunction will open the field for research and the development of novel strategies for intervention will encourage early detection of subclinical disease and will help in the stratification of cardiovascular risk in agreement with the new concept of precision medicine

Although myocardial ischaemia usually manifests as a consequence of
atherosclerosis-dependent obstructive epicardial coronary artery
disease, a significant percentage of patients suffer ischaemic events in
the absence of epicardial coronary artery obstruction. Experimental and
clinical evidence highlight the abnormalities of the coronary
microcirculation as a main cause of myocardial ischaemia in patients
with `normal or near normal' coronary arteries on angiography. Coronary
microvascular disturbances have been associated with early stages of
atherosclerosis even prior to any angiographic evidence of epicardial
coronary stenosis, as well as to other cardiac pathologies such as
myocardial hypertrophy and heart failure. The main objectives of the
manuscript are (i) to provide updated evidence in our current
understanding of the pathophysiological consequences of microvascular
dysfunction in the heart; (ii) to report on the current knowledge on the
relevance of cardiovascular risk factors and comorbid conditions for
microcirculatory dysfunction; and (iii) to evidence the relevance of the
clinical consequences of microvascular dysfunction. Highlighting the
clinical importance of coronary microvascular dysfunction will open the
field for research and the development of novel strategies for
intervention will encourage early detection of subclinical disease and
will help in the stratification of cardiovascular risk in agreement with
the new concept of precision medicine
Long-term outcomes and cost effectiveness of high-dose dexamethasone for cardiac surgery: a randomised trial
Prophylactic intra-operative administration of dexamethasone may improve short-term clinical outcomes in cardiac surgical patients. The purpose of this study was to evaluate long-term clinical outcomes and cost effectiveness of dexamethasone versus placebo. Patients included in the multicentre, randomised, double-blind, placebo-controlled DExamethasone for Cardiac Surgery (DECS) trial were followed up for 12 months after their cardiac surgical procedure. In the DECS trial, patients received a sing

The cardiovascular system is significantly affected in coronavirus disease-19 (COVID-19). Microvascular injury, endothelial dysfunction, and thrombosis resulting from viral infection or indirectly related to the intense systemic inflammatory and immune responses are characteristic features of severe COVID-19. Pre-existing cardiovascular disease and viral load are linked to myocardial injury and worse outcomes. The vascular response to cytokine production and the interaction between severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and angiotensin-converting enzyme 2 receptor may lead to a significant reduction in cardiac contractility and subsequent myocardial dysfunction. In addition, a considerable proportion of patients who have been infected with SARS-CoV-2 do not fully recover and continue to experience a large number of symptoms and post-acute complications in the absence of a detectable viral infection. This conditions often referred to as 'post-acute COVID-19' may have multiple causes. Viral reservoirs or lingering fragments of viral RNA or proteins contribute to the condition. Systemic inflammatory response to COVID-19 has the potential to increase myocardial fibrosis which in turn may impair cardiac remodelling. Here, we summarize the current knowledge of cardiovascular injury and post-acute sequelae of COVID-19. As the pandemic continues and new variants emerge, we can advance our knowledge of the underlying mechanisms only by integrating our understanding of the pathophysiology with the corresponding clinical findings. Identification of new biomarkers of cardiovascular complications, and development of effective treatments for COVID-19 infection are of crucial importance
