Supplementary Video 2) revealed moderate asymmetric septal LV hypertrophy (interventricular septum thickness 14 mm, posterior wall thickness 9 mm), mildly reduced LV ejection fraction (45%), apical akinesia, and an image suggestive of thrombus, explaining the cardioembolic stroke. Cardiovascular magnetic resonance (CMR) confirmed the diagnosis of HCM, with extensive apical fibrosis and akinesia of the apical segments, outlining an apical aneurysm and thrombus (Figure 2). Coronary angiography was performed regarding the possibility of concomitant ischemic heart disease, ruling out obstructive coronary artery disease. Serologic examination for Trypanosoma cruzi was negative. The patient was started on systemic anticoagulation with a vitamin K antagonist (VKA). Considering the diagnosis of HCM with extensive apical fibrosis and an apical aneurism, after patient-shared decision-making, it was decided to place a subcutaneous implantable cardioverter-defibrillator (S-ICD). He was discharged after 18 days. At the 1-year follow-up, control transthoracic echocardiography showed complete resolution of the apical thrombus, and the patient remained on systemic anticoagulation with a VKA. HCM is a relatively common but still underdiagnosed cardiac disease. 1 This case illustrates an extremely rare and life-threatening non-cardiac first presentation of HCM. This unusual HCM phenotype with a thin-walled, scarred LV apical aneurysm is associated with an increased risk of sudden arrhythmic death and thromboembolic stroke. 2,3

Background: Warfarin is an oral anticoagulant that is very useful in preventing thromboembolism, though it is considered a drug with a high risk of causing adverse events. Considering the practical challenges in controlling oral anticoagulation, the patients on warfarin could benefit from educational strategies aimed at behavioral changes, active participation in self-care, and adherence to drug therapy.

Objective: The aim was to construct and validate the EmpoderACO protocol for behavioral changes in warfarin patients.

Methods: The methodological steps were: definition of concepts and domains of self-care, identification of objectives, construction and selection of items, assessment of content validity, and pre-test in the target population.

Results: Relevance, adequacy, clarity, and internal reliability of the instrument's items were assessed by a multidisciplinary judges committee (JC) through the E-surv web platform, obtaining an average agreement of ≥0.91. The understanding of the instrument measured by the target population revealed adequate clarity with a coefficient average of 0.96.

Conclusion: EmpoderACO can aid in qualifying the communication process between medical professionals and patients, as well as in improving adherence to both treatment and clinical outcomes, and can be replicated in healthcare settings.

背景:华法林是一种口服抗凝药,在预防血栓栓塞方面非常有用,但它被认为是一种极易引起不良反应的药物。考虑到控制口服抗凝药的实际困难,华法林患者可以从旨在改变行为、积极参与自我护理和坚持药物治疗的教育策略中获益:目的:构建并验证针对华法林患者行为改变的 EmpoderACO 方案:方法步骤包括:定义自我护理的概念和领域、确定目标、构建和选择项目、评估内容效度以及在目标人群中进行预测试:由一个多学科评委委员会(JC)通过 E-surv 网络平台对工具项目的相关性、适当性、清晰度和内部可靠性进行了评估,获得的平均一致性≥0.91。目标人群对该工具的理解程度显示出足够的清晰度,平均系数为 0.96:EmpoderACO 有助于改善医务人员与患者之间的沟通过程,提高患者对治疗和临床结果的依从性,可在医疗机构中推广使用。

Background: Myocardial bridges (MB) are anatomical anomalies with possible clinical repercussions; hence, their understanding deserves attention.

Objective: To determinate the prevalence and characterize MB in human hearts from the state of Ceará. Methods: Fifty hearts of adult human cadavers from the Medicine School of Federal University of Ceará, Brazil. The hearts were dissected to identify MBs that pass over part of the coronary artery. The segment of the artery (proximal, middle, and distal) with a bridge was identified. The external diameter of the artery at the proximal and distal points of the MB was measured. The length and thickness of the MB were also measured with an electronic caliper. The muscle index (MMI) of the MB was calculated as the product of length and thickness expressed in millimeters. The significance level adopted in the statistical analysis was 5%.

Results: MB was confirmed in 40% of sample. Approximately one third of the sample had only 1 MB. MB was most frequently found over the anterior interventricular branch of the left coronary artery (59.25%, p=0.02), and its prevalence in other branches was much lower (22.23%). The most affected segments of arteries were the superior (44.44%) and medium (40.74%). The mean diameter of arteries proximal to the MB was 2.38±0.97mm (range=0.78-5.15mm), and the diameter distal to the MB was 1.71±0.75mm (range=0.42-3.58mm). The length was measured as mean=8.55±5.27mm, while the mean thickness was 0.89±0.33mm.

Conclusion: A high prevalence of MB is more likely to affect the left coronary artery system with larger MMI than other affected branches.

背景:心肌桥(MB)是一种可能引起临床反应的解剖异常;因此,他们的理解值得关注。目的:了解心肌梗死患者心肌MB的患病率及特征。方法:取材于巴西塞埃尔联邦大学医学院成人尸体50具心脏。解剖心脏以确定通过部分冠状动脉的MBs。确定了带桥的动脉段(近、中、远)。测量MB近端和远端动脉外径。同时用电子卡尺测量MB的长度和厚度。MB的肌肉指数(muscle index, MMI)计算为长度与厚度的乘积,单位为毫米。统计学分析采用显著性水平5%。结果:40%的标本确诊为MB。大约三分之一的样本只有1 MB。MB最常见于左冠状动脉前室间支(59.25%,p=0.02),其他分支的患病率要低得多(22.23%)。受影响最大的动脉段为上动脉(44.44%)和中动脉(40.74%)。动脉近端平均直径为2.38±0.97mm(范围0.78 ~ 5.15mm),远端平均直径为1.71±0.75mm(范围0.42 ~ 3.58mm)。长度平均值为8.55±5.27mm,厚度平均值为0.89±0.33mm。结论:MMI较大的左冠状动脉系统比其他分支更易发生MB的高发。
