The influence of climate change on human cardiovascular function.

The influence of climate change on human cardiovascular function. Arch Environ Occup Health. 2020 Mar 23;:1-9 Authors: Gostimirovic M, Novakovic R, Rajkovic J, Djokic V, Terzic D, Putnik S, Gojkovic-Bukarica L Abstract Climate change is considered to have great impact on human health. The heat waves have been associated with excess morbidity and mortality of cardiovascular diseases (CVD) across various populations and geographic locations. Important role in the heat-induced cardiovascular damage has endothelial dysfunction. It has been noticed that hot weather can impair tone and structure of the blood vessels via interfering with variety of biological factors such as nitric oxide synthesize, cytokine production and systemic inflammation. Also, due to dehydration and increased blood viscosity, by promoting thrombogenesis, heat has important impact on patients with atherosclerosis. During chronic exposure to the cold or hot weather cardiovascular function can be decreased, leading to a higher risk of developing heart attack, malignant cardiac arrhythmias, thromboembolic diseases and heat-induced sepsis like shock. It has been shown that changes in the ambient temperature through increasing blood pressure, blood viscosity, and heart rate, contribute to the cardiovascular mortality. The majority of deaths due to heat waves especially affect individuals with preexisting chronic CVD. This population can experience a decline in the health status, since extreme...

CONCLUSIONS: Further studies are required in order to establish the complicated association between SARS-CoV-2 infection and its effects on the cardiovascular system. Our knowledge regarding diagnostic approaches, therapeutic management and preventive measures is constantly enriched throughout an abundance of ongoing research in the respective fields.

Authors: Nudi F, Nudi A, Neri G, Procaccini E, Schillaci O, Versaci F, Frati G, Biondi-Zoccai G Abstract BACKGROUND: The management of patients with unprotected left main (LM) coronary artery disease remains challenging, with recent data casting a shadow of doubt on the safety of percutaneous coronary intervention. We aimed at describing the features of patients undergoing myocardial perfusion imaging subsequently found to have LM disease. METHODS: We queried our institutional database for subjects without prior revascularization or myocardial infarction (MI), who had undergone MPI followed by invasive coronary...

Authors: Poznyak AV, Zhang D, Grechko AV, Wu WK, Orekhov AN Abstract Atherosclerosis is a major cause of disease-related mortality around the globe. The main characteristic of the disease is an accumulation of plaque on the arterial wall and subsequent erosion or rupture of some plaques. Atherosclerosis often leads to cardiovascular disease and such acute complications as myocardial infarction or ischaemic stroke due to thrombus formation. Most recent advances in atherosclerotic research state that the modifications of low- density lipoprotein (LDL) are one of the most significant stages in the disease initiation, ...

CONCLUSIONS: If the results are confirmed in further studies, iCEB seems to be a simple, easily measurable and non-invasive marker to predict cannabinoid-induced ventricular arrhythmias. PMID: 32472984 [PubMed - as supplied by publisher]

This study found that though it is often associated with coronary artery disease (CAD), it can also occur in those without significant CAD. It was not specifically associated with disease of right coronary artery disease. This cardioinhibitory response may be a manifestation of the Bezold-Jarisch reflex. Bezold-Jarisch reflex inhibits sympathetic activity (sympathetic withdrawal) and increases parasympathetic activity, resulting in bradycardia, which may be associated with vasodilatation, nausea and hypotension. Bezold-Jarisch has been described in the setting of inferior wall infarction and coronary angiography. Origin...

Conclusions: Many unnecessary tests are obtained to evaluate syncope. Selecting tests based on history and examination and prioritizing less expensive and higher yield tests would ensure a more informed and cost-effective approach to evaluating older patients with syncope._____________________________________________________________________________4)    Reed MJ.  The ROSE (Risk Stratification of syncope in the emergency department) Study.  J Am Coll Cardiol, 2010; 55:713-721, doi:10.1016/j.jacc.2009.09.049  Objectives: The aim of this study was to develop and validate a clinical deci...
