Comparative StudyReperfusion strategies and quality of care in 5339 patients age 80 years or older presenting with ST-elevation myocardial infarction: analysis from get with the guidelines-coronary artery disease.
Data regarding reperfusion strategies, adherence to national guidelines, and in-hospital mortality in ST-elevation myocardial infarction (STEMI) patients age ≥80 years are limited. The aim of this study was to determine current reperfusion trends, medical treatment, and in-hospital mortality during STEMI in older adults. ⋯ Among patients ≥80 years old admitted with STEMI to GWTG-CAD hospitals, less than half undergo mechanical or pharmacological reperfusion. However, the proportion of patients undergoing PPCI has increased substantially over the 8-year study period. Patients undergoing PPCI or TL had lower in-hospital mortality compared with the NR strategy.

Independent association between obstructive sleep apnea and noncalcified coronary plaque demonstrated by noninvasive coronary computed tomography angiography.
Coronary artery atherosclerosis has been associated with obstructive sleep apnea (OSA). However, the type and severity of plaque formation have not been characterized. This study evaluated the association of coronary noncalcified plaques and severity of stenosis in patients with OSA. ⋯ Our study finds that the frequency of noncalcified/mixed plaques is much higher in patients with OSA than in non-OSA patients. Patients with OSA also have more severe stenosis and a higher number of vessels involved. This study adds to a growing body of data regarding our understanding of the association of OSA and atherosclerosis.
