Multicenter Study Observational Study
Management and 1-year outcomes of patients with atrial fibrillation in the Middle East: Gulf survey of atrial fibrillation events.
We describe management and outcomes of patients with nonvalvular atrial fibrillation (AF) in the Middle East. Consecutive patients with AF presenting to emergency departments (EDs) were prospectively enrolled. Among 1721 patients with nonvalvular AF, mean age was 59 ± 16 years and 44% were women. ⋯ Prior history of heart failure and peripheral vascular disease was independent mortality predictors. Our patients are relatively young with significant cardiovascular risk. Their anticoagulation treatment is suboptimal, and 1-year all-cause mortality and stroke/TIA event rates are relatively high.

Multicenter Study
Health-related quality of life in coronary heart disease in Korea: the Korea National Health and Nutrition Examination Survey 2007 to 2011.
Using data from 2007 to 2011 of the Korea National Health and Nutrition Examination Survey, we evaluated the influence of coronary heart disease (CHD) on health-related quality of life (HRQoL) as measured by the EQ-5D in comparison with the general population and the predictors of HRQoL in CHD. Compared with the general population, HRQoL was impaired in the EQ-5D dimensions of mobility, usual activities, pain/discomfort, and anxiety/depression. ⋯ In subjects with CHD, the predictors for a low EQ-5D index were old age, female sex, low education, stroke, and noncardiovascular comorbidities, and the predictors for a low EQ Visual Analogue Scale were low income and noncardiovascular comorbidities. For the improvement in HRQoL, preventing stroke and noncardiovascular comorbidities is important, especially among female and older Asian patients with CHD.

Multicenter Study Comparative Study Observational Study
Saudi Atrial Fibrillation Survey: national, observational, cross-sectional survey evaluating atrial fibrillation management and the cardiovascular risk profile of patients with atrial fibrillation.
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. The Saudi Atrial Fibrillation Survey registry was designed to provide epidemiological and clinical data on patients with AF. The registry included 400 consecutive patients who met the eligibility criteria. ⋯ This is the first nationwide registry of patients with AF in Saudi Arabia. Compared to developed countries, our patients with AF are relatively young and have higher rates of diabetes and rheumatic heart disease. Rate control is the main strategy currently used for managing AF.

Multicenter Study
Use of emergency medical services in the second gulf registry of acute coronary events.
Data are scarce regarding emergency medical service (EMS) usage by patients with acute coronary syndrome (ACS) in the Arabian Gulf region. This 9-month in-hospital prospective ACS registry was conducted in Arabian Gulf countries, with 30-day and 1-year follow-up mortality rates. Of 5184 patients with ACS, 1293 (25%) arrived at the hospital by EMS. ⋯ The EMSs are underused in the Arabian Gulf region. Short- and long-term mortality rates in patients with ACS are similar between those who used and did not use EMS. Quality improvement in the EMS infrastructure and establishment of integrated STEMI networks are urgently needed.

Multicenter Study Clinical Trial Controlled Clinical Trial
Chronic venous insufficiency: worldwide results of the RELIEF study. Reflux assEssment and quaLity of lIfe improvEment with micronized Flavonoids.
Chronic venous insufficiency (CVI) results in considerable morbidity and may seriously affect patients' quality of life. The RELIEF (Reflux assEssment and quaLity of life improvEment with micronized Flavonoids) Study was a prospective controlled study designed to assess differences in the severity and in the evolution of symptoms and signs of CVI according to presence or not of venous reflux. Patients were thus separated into 2 comparative groups: those presenting venous reflux and those without venous reflux. ⋯ The relationship shown in this study between these parameters and clinical CEAP classification reflects the progressive nature of CVI. Despite obvious symptoms of CVI, a very low percentage (21.8%) of the "intention-to-treat" (ITT) population had previously been treated. This was the case whether venous reflux was present or not.
