Dysglycemia, in this survey defined as impaired glucose tolerance (IGT) or type 2 diabetes, is common in patients with coronary artery disease (CAD) and associated with an unfavorable prognosis. This European survey investigated dysglycemia screening and risk factor management of patients with CAD in relation to standards of European guidelines for cardiovascular subjects. RESEARCH DESIGN AND METHODS The European Society of Cardiology's European Observational Research Programme (ESC EORP) European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EUROASPIRE) V (2016-2017) included 8,261 CAD patients, aged 18-80 years, from 27 countries. If the glycemic state was unknown, patients underwent an oral glucose tolerance test (OGTT) and measurement of glycated hemoglobin A 1c. Lifestyle, risk factors, and pharmacological management were investigated. RESULTS A total of 2,452 patients (29.7%) had known diabetes. OGTT was performed in 4,440 patients with unknown glycemic state, of whom 41.1% were dysglycemic. Without the OGTT, 30% of patients with type 2 diabetes and 70% of those with IGT would not have been detected. The presence of dysglycemia almost doubled from that selfreported to the true proportion after screening. Only approximately one-third of all coronary patients had completely normal glucose metabolism. Of patients with known diabetes, 31% had been advised to attend a diabetes clinic, and only 24% attended. Only 58% of dysglycemic patients were prescribed all cardioprotective drugs, and use of sodium-glucose cotransporter 2 inhibitors (3%) or glucagon-like peptide 1 receptor agonists (1%) was small. CONCLUSIONS Urgent action is required for both screening and management of patients with CAD and dysglycemia, in the expectation of a substantial reduction in risk of further cardiovascular events and in complications of diabetes, as well as longer life expectancy.
This study was designed to evaluate the effects of chronic exercise training on carnitine acetyl- and palmitoyltransferase activity and the distribution of carnitine forms and concentrations in various organs and tissues of female rats. Sprague-Dawley rats were swim trained 6 days/wk and progressed to 75-min swims twice daily (with 3% of their total body weight attached to the medial portion of the tail) at the end of 5 wk of training. Sedentary (S, n = 12) and trained (T, n = 13) animals were killed by decapitation, and the livers, kidneys, hearts, and several skeletal muscle types were removed and immediately frozen in liquid N2 and/or extracted for enzyme activity assays. Blood was collected and plasma was stored frozen. Samples were assayed for free, acid-soluble, and acid-insoluble carnitine. Free carnitine increased significantly (P less than 0.03) in T hearts. Free carnitine remained unchanged in liver, but short-chain acylcarnitines increased significantly (P less than 0.001). There was a significant (P less than 0.001) reduction in long-chain acylcarnitines in kidney in the trained rats, and plasma short-chain acylcarnitine levels also decreased (P less than 0.001). Several significant changes in carnitine distribution also occurred in the superficial and deep portions of the vastus lateralis and in the mixed gastrocnemius muscles. There was a significant reduction in carnitine acetyltransferase activity with training in both the soleus (P less than 0.02) and superficial gastrocnemius (P less than 0.002) muscles. The deep portion of the gastrocnemius muscle contained significantly higher activity than either the superficial portion or the soleus.(ABSTRACT TRUNCATED AT 250 WORDS)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
