Anatomo-functional substrate of high risk arrhythmia after myocardial infarct

Ventricular arrhythmias detected in the late-hospital phase of myocardial infarction have been identified as a risk factor for sudden death, being their prognostic value independent of ventricular function. However, relations between both factors are not clarified. In order to study hypothetic associations between ventricular arrhythmias and some clinical, hemodynamic and angiographic variables, 60 patients (52 males, 8 females) underwent 24-hour Holter recordings and cardiac catheterization with left ventricular and coronary angiographies, 3-5 weeks after hospital admission. Past history data, acute phase complications and hemodynamic and angiographic results were compared between patients with and without significant ventricular arrhythmias during Holter monitoring (10 or more PVC's/hour and/or repetitive forms). No significant differences were found between both groups neither in mean age nor in the incidence of previous angina or infarction, cerebral ischemia, diabetes, lipid disorders or subjective feeling of being under psychological stress. Prior history of arterial hypertension was, however, significantly more frequent in patients with ventricular arrhythmias (53.3% vs 17.8%; p = 0.0183). No differences were observed in the localization of the infarct or in the complications during the acute phase (CPK peak, Killip's score, angina after 24 hours of evolution, intraventricular or A-V conduction disorders and supraventricular and ventricular arrhythmias). Among hemodynamic data, only left ventricular and aortic systolic pressures were different in both groups, being significantly higher in patients with ventricular arrhythmias. There were not differences in left ventricular segmentary contraction and in number of coronary vessels involved. To conclude, significant ventricular arrhythmias were recorded in 25% of patients.(ABSTRACT TRUNCATED AT 250 WORDS)     

Effectiveness of brief intervention on non-dependent alcohol drinkers (EBIAL): a Spanish multi-centre study

OBJECTIVE: The project was designed to compare the effectiveness of brief intervention (BI) versus simple advice (SA) in the secondary prevention of hazardous alcohol consumption. METHODS: A randomized controlled trial with a 12-month follow-up was conducted. A total of 74 community-based primary care practices (328 physicians) located in 13 Spanish autonomous regions were recruited initially. Out of 546 men screened, only 229 were randomized into BI (n = 104) and SA (n = 125); 44.6% of practices finalized the study. The interventions on the BI group consisted of a 15-minute counselling visit carried out by physicians which included: (i) alcohol quantification, (ii) information on safe limits, (iii) advice, (iv) drinking limits agreement, (v) self-informative booklet with drinking diary record and (vi) unscheduled reinforcement visits. The SA group spent 5 minutes which included (i), (ii) and (iii). RESULTS: There were no significant differences between both groups at baseline on alcohol use, age, socioeconomic status and CAGE score. After the 12-month follow-up there was a significant decrease in frequency of excessive drinkers (67% of BI group reached targeted consumption, versus 44% of SA; P < 0.001) as well as weekly alcohol intake reduction (BI reached 52 versus 32% in SA; P < 0.001). A trend to improve outcome with the number of reinforcement visits was found with BI. The only predictor of success was the initial alcohol consumption level. CONCLUSIONS: Brief intervention is more effective than simple advice to reduce alcohol intake on adult men who attend primary care services in Spain.     

Valoración formativa: experiencia de las unidades docentes de medicina familiar y comunitaria de Cataluña

The purpose of this article is to report on the experience in formative evaluation that was carried out in the Catalonian family and community medicine teaching units during the years 2001–2007. This formative evaluation project included the use of several evaluation tools such as, self-listening, video-recording, structured observation of clinical practice, cases by computer and simulated patients. Different resident intakes have participated in the development of the project, as well as their teaching unit tutors and coordinators. This accumulated experience has allowed it to progress into the field of formative evaluation, and to adapt and integrate the activities that were being carried out in a resident portfolio, which in our opinion is the best tool for the formative evaluation of the family medicine resident.
