Women-focused cardiovascular rehabilitation (CR; phase II) aims to better engage women, and might result in better quality of life than traditional programs. This first clinical practice guideline by the International Council of Cardiovascular Prevention and Rehabilitation (ICCPR) provides guidance on how to deliver women-focused programming. The writing panel comprised experts with diverse geographic representation, including multidisciplinary health care providers, a policy-maker, and patient partners. The guideline was developed in accordance with Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Reporting Items for practice Guidelines in HealTh care (RIGHT). Initial recommendations were on the basis of a meta-analysis. These were circulated to a Delphi panel (comprised of corresponding authors from review articles and of programs delivering women-focused CR identified through ICCPR’s audit; N = 76), who were asked to rate each on a 7-point Likert scale in terms of impact and implementability (higher scores positive). A Web call was convened to achieve consensus; 15 panelists confirmed strength of revised recommendations (Grading of Recommendations Assessment, Development, and Evaluation [GRADE]). The draft underwent external review from CR societies internationally and was posted for public comment. The 14 drafted recommendations related to referral (systematic, encouragement), setting (model choice, privacy, staffing), and delivery (exercise mode, psychosocial, education, self-management empowerment). Nineteen (25.0%) survey responses were received. For all but 1 recommendation, ≥ 75% voted to include; implementability ratings were < 5/7 for 4 recommendations, but only 1 for effect. Ultimately 1 recommendation was excluded, 1 separated into 2 and all revised (2 substantively); 1 recommendation was added. Overall, certainty of evidence for the final recommendations was low to moderate, and strength mostly strong. These recommendations and associated tools can support all programs to feasibly offer some women-focused programming.  相似文献

BackgroundUse of percutaneous mechanical circulatory support has grown exponentially. Vascular complications remain a growing concern and best practices for device removal do not exist. We describe a novel post-closure technique for the next generation Impella CP removal and immediate hemostasis.MethodsThis study is a single center, retrospective, exploratory analysis of 11 consecutive patients receiving an Impella CP for either high-risk PCI or cardiogenic shock and then referred for post-closure compared to 20 patients receiving manual compression for Impella CP removal between 2017 and 2019.ResultsMean age range was 62.7–65.4 years and 50–65% male between groups. Average duration of Impella CP treatment ranged from 3.4 to 5.2 days. Patients referred for post-closure had significantly lower rates of all-cause adverse vascular events (0% versus 40%; n = 0/11 versus n = 8/20; p = 0.01). There was no significant difference in BARC 3 or greater bleeding, transfusion requirement, hospitalization duration or intensive care duration between removal strategies.ConclusionThe novel post-closure technique may significantly reduce vascular complications associated with device removal and may improve clinical outcomes for these critically ill patients.  相似文献
