The second Euro Heart Survey on acute coronary syndromes: Characteristics, treatment, and outcome of patients with ACS in Europe and the Mediterranean Basin in 2004.

AIMS: Our study aimed to examine the management of acute coronary syndromes (ACS) in Europe and the Mediterranean basin, and to compare adherence to guidelines with that reported in the first Euro Heart Survey on ACS (EHS-ACS-I), 4 years earlier. METHODS AND RESULTS: In a prospective survey conducted in 2004 (EHS-ACS-II), data describing the characteristics, treatment, and outcome of 6385 patients diagnosed with ACS in 190 medical centres in 32 countries were collected. ACS with ST-elevation was the initial diagnosis in 47% of patients, no ST-elevation in 48%, and undetermined electrocardiographic pattern in 5% of patients. Comparison of data collected in 2000 and 2004 showed similar baseline characteristics, but greater use of recommended medications and coronary interventions in EHS-ACS-II. Among patients with ST-elevation, the use of primary reperfusion increased slightly (from 56 to 64%), with a significant shift from fibrinolytic therapy to primary percutaneous coronary intervention (PPCI). The use of PPCI rose from 37 to 59% among those undergoing primary reperfusion therapy. Analysis of data in 34 centres that participated in both surveys showed even greater improvement with respect to the use of recommended medical therapy, interventions, and outcome. CONCLUSION: Data from EHS-ACS-II suggest an increase in adherence to guidelines for treatment of ACS in comparison with EHS-ACS-I.

Decrease in triglyceride level by bezafibrate is related to reduction of recurrent coronary events: a Bezafibrate Infarction Prevention substudy.

BACKGROUND: Fibrates were reported to be effective in reducing recurrent coronary events in coronary heart disease patients with elevated triglycerides. It is not known whether this effect is related to the extent of triglyceride reduction. METHODS: Participants comprised 3090 coronary heart disease patients enrolled in the Bezafibrate Infarction Prevention study, which showed a nonsignificant reduction (9.4%; P=0.26) in fatal or nonfatal myocardial infarction and sudden death during a mean follow-up time of 6.2 years. RESULTS: Significant reduction in triglyceride serum level was evident only among patients allocated to bezafibrate, ranging between 0.06 mmol/l (5 mg/dl) in the lowest decile of baseline triglycerides level and 0.68 mmol/l (60 mg/dl) in the highest baseline decile. The extent of triglyceride reduction with bezafibrate was significantly associated with the reduction of risk; relative risk reduction of 55% (hazards ratio: 0.45; 95% confidence interval: 0.24-0.84) was observed among patients with baseline triglycerides>or=2.26 mmol/l who reduced triglyceride level to >0.50 mmol/l (>44.3 mg/dl). In contrast, the risk of recurrent events among patients treated with bezafibrate and achieving less triglyceride reduction or failing to reduce triglyceride level was not significantly different from that of patients treated with placebo. CONCLUSION: Bezafibrate treatment was associated with significant risk reduction among coronary heart disease patients with elevated triglyceride levels that substantially reduced their triglyceride level with treatment.

Endoscopy in asymptomatic minidose aspirin consumers.

Aspirin is widely used for its antiplatelet activity, but it harbors a risk of severe adverse gastrointestinal effects, such as bleeding and perforation, especially in elderly people. Our aim to assess the prevalence of upper gastrointestinal lesions and the effect of aspirin on the gastrointestinal mucosa in asymptomatic subjects taking minidose aspirin (100 to 325 mg per day) for more than 3 months. A prospective, open design was used. Patients attending the ophthalmology and cardiology outpatient clinics who had a medical history of more than 3 months of regular aspirin consumption were referred for esophagogastroduodenoscopy (EGD). Of the 90 patients referred for EGD, 44 were symptomatic (epigastric pain or dyspepsia) and were excluded from the study. The 46 asymptomatic patients included 22 men and 24 women of mean age 70 +/- 10 years (range, 36 to 87 years); 32% were current or former smokers. Mean daily aspirin dose was 129.34 +/- 76.61 mg. Only 24% were taking a gastroprotective agent. EGD revealed ulcer or erosions in 47.83% of the patients: erosive gastroduodenitis in 13 patients, gastric ulcer in 14, duodenal ulcer in 2, and gastric and duodenal ulcers in 2. Urease test for Helicobacter pylori infection was positive in 26%. Univariate and multivariate analysis revealed no factor other than aspirin predictive of a positive endoscopy. Minidose aspirin treatment is associated with a high prevalence of ulcerations of the stomach and duodenum.
