BACKGROUND The effects of shift work on coronary heart diseases (CHD) are well described. Most of the studies on coronary events in shift workers are supportive of the hypothesis that they are at increased risk. OBJECTIVE The objective of this study was to investigate the relation shift work has to risk of CHD in a cohort of men from different Asian races(More)
BACKGROUND Why do some patients suffer acute myocardial infarction (MI) despite angiographically normal coronary arteries (NL + MI) whereas others enjoy an acute MI-free life despite extensive three-vessel disease (3VD-MI)? The present study contrasts these two groups to identify some differences in the risk profile. METHODS In 10,000 patients admitted to(More)
AIMS To evaluate the presentation and outcome of South Asian (SAP) to Middle Eastern Arabs (MEAP) patients presenting with acute coronary syndrome. METHODS Data were collected retrospectively in Qatar between 1991 and 2010, and were analyzed according to patient ethnicity. RESULTS Of 14,593 acute coronary syndrome patients, 49% were MEAP and 51% were(More)
We assessed the prevalence of unrecognized diabetes mellitus (DM) in patients with acute coronary syndrome (ACS) as determined by elevated glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), and random plasma glucose (RPG) levels. This prospective study recruited 583 patients admitted with ACS without previous diagnosis of DM during 1-year(More)
Cardiac catheterization in Qatar was initiated in July 1982. In ten years, a total of 3900 procedures were performed at Hamad General Hospital. Computerized data registry has been maintained since 1982. Isolated coronary angiography was done in 2911 patients; of these, 2635 (90.5%) were men, and 276 (9.5%) were women, the average age of the patients was(More)
We aimed to define the temporal trend in the initial Acute Myocardial Infarction (AMI) management and outcome during the last two decades in a Middle Eastern country. A total of 10,915 patients were admitted with initial AMI with mean age of 53 ± 11.8 years. Comparing the two decades (1991-2000) to (2001-2010), the use of antiplatelet drugs increased from(More)
In a prospective study, a radionuclide technique was used to evaluate the limb blood flow (LBF) changes in 30 patients undergoing dynamic (n=15) or balloon (n=15) angioplasty for arterial occlusions or stenoses, respectively. The results were compared with Doppler Ankle Brachial Index (DABI) and treadmill exercise tests. Whilst LBF values (ml of blood flow(More)
AIM OF THE STUDY We studied the clinical profile, management, and outcomes of patients with out-of-hospital cardiac arrest (OHCA) with and without ST-elevation myocardial infarction (STEMI). METHODS Retrospective analysis of the 20-year registry data (January 1991- June 2010) was conducted on patients with cardiac disease hospitalized at Hamad General(More)
