Abstract

fetched live from OpenAlex

Background: Patients with peripheral artery disease are 6 times as likely as healthy individuals to die of cardiovascular causes within 10 years after diagnosis. Combination therapy with a statin, an angiotensinconverting enzyme (ACE) inhibitor or angiotensin II receptor blocker (ARB), and an antiplatelet agent is recommended to reduce cardiovascular events in patients with peripheral artery disease, especially those with concomitant diabetes mellitus and those who have undergone vascular surgery.Objectives: The primary objective was to determine the proportion of patients with concurrent diabetes and peripheral artery disease who were receiving therapy with a statin, ACE inhibitor or ARB, and antiplatelet agent (acetylsalicylic acid or clopidogrel) at the time of discharge after vascular surgery. The secondary objectives were to determine if target blood pressure was achieved and if smoking cessation therapy was offered and/or provided.Methods: This pilot study was a retrospective, cross-sectional chart analysis. The health records database for Alberta Health Services was searched to identify patients with diabetes who underwent vascular surgery at the Foothills Hospital in Calgary with discharge between January 1 and June 30, 2010. In addition to baseline demographic characteristics, blood pressure values at the time of admission and discharge were collected. Discharge medications, including cardiovascular medications such as statins, ACE inhibitor or ARB, and antiplatelet agents, were recorded. Descriptive analysis of the data was performed.Results: Of the 42 patients for whom charts were obtained, 25 (60%) had prescriptions for cardiovascular triple therapy (statin, ACE inhibitor or ARB, antiplatelet agent). Just over half of the patients (23 [55%]) had achieved target blood pressure (< 130/80 mm Hg) at the time of discharge. Of the 14 current smokers, 9 (64%) had documented evidence in the chart that smoking cessation counselling was offered and/or drug therapy was provided.Conclusion: Only about half of the patients in this study were receiving cardiovascular triple therapy, which suggests that many patients were not receiving optimal vascular protection. A larger study is needed to review prescribing patterns for patients with peripheral artery disease.RÉSUMÉContexte : Les patients atteints d’une maladie artérielle périphérique ont un risque six fois plus élevé de mourir d’une maladie cardiovasculaire dans les 10 ans suivant le diagnostic que les personnes non atteintes d’une telle maladie artérielle. Les traitements associant une statine, un inhibiteur de l’enzyme de conversion de l’angiotensine (ECA) ou un antagoniste des récepteurs de l’angiotensine II (ARA), et un antiplaquettaire sont recommandés pour réduire le risque d’événements cardiovasculaires chez les patients atteints d’une maladie artérielle périphérique, particulièrement ceux présentant un diabète sucré concomitant ou ayant subi une chirurgie vasculaire.Objectifs : Le principal objectif était de déterminer la proportion de patients présentant simultanément un diabète et une maladie artérielle périphérique qui recevaient un traitement associant une statine, un inhibiteur de l’ECA ou un ARA, et un antiplaquettaire (acide acétylsalicylique ou clopidogrel) au moment de leur congé de l’hôpital après une chirurgie vasculaire. Les objectifs secondaires étaient de déterminer si les chiffres tensionnels ciblés ont été atteints et si un traitement de cessation tabagique a été offert ou prodigué.Méthodes : Il s’agit d’une étude pilote menée au moyen de l’analyse transversale rétrospective de dossiers médicaux. Une recherche a été effectuée dans la base de données des dossiers médicaux des Services de santé de l’Alberta pour recenser les patients atteints de diabète qui avaient subi une chirurgie vasculaire à l’Hôpital Foothills de Calgary et reçu leur congé entre le 1er janvier et le 30 juin 2010. Les données démographiques de base ont été recueillies, de même que les chiffres tensionnels au moment de l’hospitalisation et du congé des patients. Les médicaments prescrits au congé du patient, dont les agents cardiovasculaires comme les statines, les inhibiteurs de l’ECA ou les ARA, et les antiplaquettaires, ont été relevés. Une analyse descriptive des données a été effectuée.Résultats : Des 42 patients dont les dossiers médicaux ont été obtenus, 25 (60 %) avaient reçu une prescription pour une trithérapie cardiovasculaire (statine, inhibiteur de l’ECA ou ARA, antiplaquettaire). Un peu plus de la moitié des patients (23 [55 %]) avaient atteint les chiffres tensionnels ciblés (< 130/80 mm Hg) au moment de leur congé de l’hôpital. Selon les dossiers médicaux, des 14 fumeurs, 9 (64 %) avaient eu une consultation ou reçu une pharmacothérapie pour la cessation tabagique.Conclusion : Environ seulement la moitié des patients de cette étude avaient reçu une trithérapie cardiovasculaire, ce qui suggère que plusieurs patients n’avaient pas reçu une prophylaxie vasculaire optimale. Une étude de plus grande envergure est nécessaire pour examiner les habitudes de prescription chez les patients atteints d’une maladie artérielle périphérique.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
