Coronary CT angiography can depict in-stent low-attenuation filling defects, which appear to be a reliable sign of stent restenosis, and 64-section CT depicts such defects with a high degree of accuracy.
BackgroundCoronary artery disease (CAD) is the leading cause of mortality worldwide. The present study evaluated the impact of gender in patients hospitalized with acute coronary syndromes (ACS) over a 20-year period in Qatar.MethodsData were collected retrospectively from the registry of the department of cardiology for all patients admitted with ACS during the study period (1991–2010) and were analyzed according to gender.ResultsAmong 16,736 patients who were admitted with ACS, 14262 (85%) were men and 2474 (15%) were women. Cardiovascular risk factors were more prevalent among women in comparison to men. On admission, women presented mainly with non-ST-elevation ACS and were more likely to be undertreated with β-blockers (BB), antiplatelet agents and reperfusion therapy in comparison to men. However, from 1999 through 2010, the use of aspirin, angiotensin-converting enzyme inhibitors and BB increased from 66% to 79%, 27% to 41% and 17% to 49%, respectively in women. In the same period, relative risk reduction for mortality was 64% in women and 51% in men. Across the 20-year period, the mortality rate decreased from 27% to 7% among the Middle Eastern Arab women. Multivariate logistic regression analysis showed that female gender was independent predictor of in-hospital mortality (odd ratio 1.51, 95% CI 1.27–1.79).ConclusionsWomen presenting with ACS are high-risk population and their in-hospital mortality remains higher for all age groups in comparison to men. Although, substantial improvement in the hospital outcome has been observed, guidelines adherence and improvement in the hospital care have not yet been optimized.
HF patients in the Middle East present at relatively younger age regardless of ethnicity. In-hospital mortality and stroke rates decreased significantly over the 20-years.
The prevalence of diabetes mellitus among patients with acute myocardial infarction in a geographically defined population in the developing world is high with a trend for poor outcomes. However, mortality was not significantly higher in diabetes mellitus than non-diabetes mellitus patients.
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.
