Background: The recent increase in the public’s interest in health matters has been accompanied by greater attention to the development of Web-based programs by many health-related professional and educational services. Wikiheart is a Web-based program that has been designed to narrow the gaps between care and secondary prevention by directly delivering knowledge to patients in their homes and communities. Purpose: To develop a Web-based program aimed at educating patients and targeted to the specific learning needs of patients with heart disease and associated risk factors. Methods and results: This pilot program is relatively easy to use, web-based educational model. It consists of a collaborative feature, the content of which can be easily edited by users, thus enabling powerful information sharing, interactive chat and article discussions. Participants are categorized into two principal groups: (1) invited or volunteer medical professionals; and (2) patients with their own experiences. This program can be used as an information resource for patients and method of real-time communication between healthcare professionals and patients. This virtual program allows patients to engage with each other, share experiences and become part of an online community. As an online interactive medical reference, this program is also intended to help patients with heart disease learn more about their specific conditions and be educated about preventive measures. For patient confidentiality, password protection would be employed and all clinical images and videos would be required to be de-identified. Material that violates patient privacy will be easily removed. Conclusions: Wikiheart aims to enable the sharing of knowledge relevant to secondary prevention and thus improve the quality of care for patients with heart disease or cardiovascular risk factors. If successfully implemented, the program is likely to enhance researchers’, healthcare providers’ and patients’ learning experiences, and communication within digital world, leading to the improvement of clinic outcome and adherence for patients. Further research is needed in order to identify the best approaches to apply these tools and ultimately boost research productivity, learning experience and patient education.

BACKGROUND: Idiopathic recurrent pericarditis (IRP) is a debilitating condition that can be recalcitrant to conventional therapy. Some patients develop steroid dependency with the attendant risks of systemic side effects and increased future recurrence. Anakinra is a recombinant human interleukin-1 receptor antagonist that reduces systemic inflammatory responses. The aim of this study was to evaluate the therapeutic role of anakinra in IRP. Methods: We retrospectively studied consenting patients with treatment refractory IRP who received anakinra, between January 2009 and November 2013. The primary end points were symptom resolution and steroid discontinuation. Results: Nine patients were followed for a median of 16.8 (IQR 1.3-24) months. Study subjects were predominantly female (7 [78%]) with a median age of 53 (IQR 38 - 58) years. All 9 patients had failed maximum tolerated doses of NSAIDs, colchicine and prednisone (median dose 20 mg [IQR 15 - 22.5]). Primary symptom was chest pain in 9 (100%), with concurrent dyspnea in 5 (56%) patients. Symptom duration prior to anakinra initiation was 24 (IQR 13 - 71) months. Indication for anakinra was steroid sparing agent in 7 (78%) and symptom control in 2 (22%) patients. The dosage was 100 mg once daily via subcutaneous injection. Baseline LVEF was 62% (IQR 59% - 67%). Echocardiographic findings include pericardial effusion in 3 (33%), pericardial thickening in 6 (67%), and constrictive physiology in 4 (44%). Pericardial enhancement on cardiac MRI was seen in 7 (78%) patients. All 9 patients (100%) had symptom improvement with complete resolution in 8 (89%) and partial resolution in 1 (11%) patient. At last follow up, all 9 (100%) patients had discontinued NSAIDs and colchicine, 5 (56%) patients discontinued and 4 (44%) had reduced prednisone dosage. All patients remained on anakinra at the end of follow up. The only reported side effect was transient injection site reaction in 4 (44%) patients. In 2 (22%) patients, attempted anakinra weaning was unsuccessful due to symptomatic flare after 6 weeks. Conclusion: Anakinra is an effective alternative agent for the management of steroid dependent IRP. It provides remarkable symptomatic amelioration, limits steroid dependency, and is associated with minimal side effects.

Background: Spontaneous coronary artery dissection (SCAD) is the principal cause of peripartum myocardial infarction (MI). Clinical features remain incompletely understood. Methods: Medical records of all women enrolled in a SCAD registry at the Mayo Clinic were reviewed to identify those who were either pregnant or ≤12 weeks postpartum at time of initial event. Diagnosis of SCAD was confirmed with coronary angiography in all cases. Obstetrical outcomes and incidence of recurrent SCAD events were assessed. Results: In total, 38 of 363 women enrolled in the registry met criteria for peripartum MI due to SCAD. Mean age at time of SCAD was 36±3 (range 27-42) years; 3 patients were pregnant at the time of initial event, and all pregnancies except 2 resulted in a live birth. Ten (26%) were diagnosed with multivessel SCAD (MV-SCAD). Most (60%) postpartum events occurred within 30 days of delivery. Antecedent co-morbidities included gestational hypertension/preeclampsia (9), fibromuscular dysplasia (7), gestational diabetes (4), and mixed connective tissue disease (1). Compared to US population birth data, women with peripartum SCAD were more likely to be ≤ 30 years at the time of first delivery (60% vs 42%) and more often multiparous (80% vs 59%). On long-term follow-up (median 3.7 years, IQR 1.1-7.1), 5 (13%) women experienced recurrent SCAD, with one episode occurring following a subsequent pregnancy. MV-SCAD was not associated with increased risk of recurrence (p=0.44). Conclusion: Women with peripartum SCAD are both older than the general obstetrical population at the time of first pregnancy and frequently multiparous at time of initial SCAD event. The highest frequency of SCAD was encountered during the first postpartum month, suggesting variations in hormonal and hemodynamic factors may contribute to SCAD events in susceptible women.

Background: Spontaneous coronary artery dissection (SCAD) typically presents as acute coronary syndrome in young women with no cardiovascular risk factors. It is associated with high morbidity and mortality, and is underdiagnosed. Despite this, risk factors and pathophysiology associated with SCAD are not completely understood. The objective of the present case series was to assess family history as a risk factor in patients with SCAD. Methods: We reviewed the medical records and questionnaires of 335 participants in the Mayo Clinic SCAD Registry for history of MI, SCAD or CAD in another family member. Coronary angiograms of all affected family members were reviewed by a senior interventional cardiologist. Results: We identified 4 familial cases of SCAD comprised of affected mother-daughter, identical twin sister, sister and aunt-niece pairs, implicating both recessive and dominant modes of inheritance. The mother-daughter pair also reported history of fatal MI in 3 maternal relatives including grandmother, great grandmother and great aunt. One of the affected twin sisters died of SCAD, which was confirmed on autopsy. None of the subjects had other potential risk factors for SCAD including extreme exercise, polycystic kidney disease, connective tissue disorder, peripartum status or diagnosed non-coronary fibromuscular dysplasia. The details of their demographics, risk factors, presentation, location of SCAD and management are presented in the table. Conclusions: This series is the first to identify a familial association in SCAD suggesting a genetic predisposition. Recognition of SCAD as a heritable disorder has implications for at-risk family members and furthers our understanding of the pathophysiology of this complex disease. Whole exome sequencing in these families provides a unique opportunity to identify the molecular underpinnings of SCAD susceptibility.

Introduction: At-work stress is rapidly becoming a significant contributory cause of occupational disease, while sedentary work and dietary indiscretion, taken together, have contributed to cardiovascular disease, known to be associated with substantial morbidity and mortality. The aim of the CV-Ecosystem Model is to provide an individual approach by systematic environmental modification of the work site. Methods and Results: Our model which we term the CV-Ecosystem Model includes two basic tenets: 1) Workstation technologic design 2) Flexible physiologic activity. Workstation technologic design utilizes the services of a certified Ergonomist to engineer a comfortable, safe, and effective work environment. It is tailored to the unique physiologic needs of the worker while enhancing productivity within different environments. Computer aided design software would evaluate ergonomics to maximally mitigate the risk and incidence of eye strain, musculoskeletal disorders, repetitive movement disorders such as Carpal Tunnel Syndrome, etc unique to that work activity. Flexible physiologic activity would permit a worker to actively focus on basic needs during work time, on site; this would include exercise activity and food intake, channeled into healthy options. Exercise time would provide a sense of calm during stressful projects and enhance emotional well-being. In this regard, a three hour period of time, weekly, could be allocated to fitness or meditation. Conveniently located food stations could provide a variety of healthy, plant-based, fresh food options. Both would come with flexible, relative control and scheduling of these activities, within a social environment and context. Conclusions: The CV Ecosystem Model, due to its simple technology and relative low cost, could be successfully implemented in a number of enterprises, including all healthcare facilities, with benefit to employee health, wellbeing, and favorable to the business bottom line.

Introduction: Compared to Whites, African-Americans (AAs) have 82% lower odds of meeting ideal levels for five or more cardiovascular (CV) health components that comprise the American Heart Association’s Life’s Simple 7, an evidenced-based metric of seven health promoting behaviors and biological factors that improve CV outcomes. Given expanding mobile technology use among AAs, mobile health (mHealth) interventions are promising avenues to promote CV health within this population. Hypothesis: An evidence-based, theory-informed, culturally relevant, community-based mHealth lifestyle intervention would improve CV health among AAs adults. Methods: Five predominately AA churches collaborated in a community-based participatory research approach to develop a 10-week CV health and wellness digital application-based program ( FAITH! App ). We enrolled AA adults [N=50, mean age 49.6 (SD 12.7), 70% women (35/50)] into a single group, 10-week intervention centered on the FAITH! App with adjunct in-person sessions. The FAITH! App included ten core video education modules from health professionals on CV health, interactive diet/physical activity self-monitoring and a sharing board. The primary outcome was change in individual CV health behaviors (body mass index, physical activity, diet, cigarette smoking) and biological factors (blood pressure (BP), total cholesterol, fasting glucose) from baseline to post-intervention at 28 weeks. Results: Participants were overall high CV risk at baseline (hypertensive [40% (20/50)] with poor/intermediate physical activity [79% (37/47)] and diet [72% (36/50)]). At 28 weeks, there were substantial improvements in CV health factors (systolic and diastolic BPs), CV health behaviors (diet, physical activity) and psychological/psychosocial variables to promote behavior change ( Table 1 ). Conclusions: This study supports the benefits of a culturally relevant, community-based mHealth lifestyle intervention to promote CV health among AAs with high cardiometabolic risk.

Introduction: Spontaneous coronary artery dissection (SCAD) is an uncommon but increasingly recognized cause of acute coronary syndrome and sudden cardiac death. We aim to review the occurrence of atrial fibrillation and atrial flutter in the Mayo Clinic SCAD Registry (MCSR) to gain insight into the association of SCAD and atrial arrhythmias. Methods: Atrial arrhythmias were queried amongst patients in the MCSR using diagnostic codes and text contained in both a large data repository known as the Advanced Cohort Explorer as well as a clinical database maintained by nurse abstractors for patients in the MCSR. All positive were manually verified using available medical records. Univariable logistic regression analysis was performed using JMP to investigate associations with classic cardiovascular risk factors. Results: A total of 1,215 patients from the Mayo SCAD registry were included. Six patients had a pre SCAD atrial arrhythmia, 19 had an atrial arrhythmia during a SCAD event, and 11 had a post SCAD atrial arrhythmia. Univariable analysis did not reveal significant associations with diabetes, hypertension, hyperlipidemia, or smoking. Conclusion: Atrial arrhythmias were not uncommonly seen in patients at the time of or after SCAD, especially after cardiac arrest or coronary artery bypass grafting. No significant associations with traditional cardiovascular risk factors were observed. Further investigation into the mechanism of atrial arrhythmia development as well as its management in the setting of SCAD is warranted.

Introduction: Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial infarction in otherwise healthy and most times presumably fit young women. In the absence of evidence for benefit or harm, exercise prescription (EXP) after SCAD remains arbitrary. We assessed EXP patterns among participants in a large multinational SCAD registry. Methods: Participants with SCAD as confirmed by coronary angiography completed surveys detailing exercise (EX) habits prior to SCAD (initial survey), and EXP from their provider on initial and subsequent visits after SCAD (follow-up survey). Demographic and clinical characteristics were collected by electronic health record review by trained nurse abstractors. EXP was categorized according to EX components that include: type, intensity, frequency, time/session, and external conditions. Results: Among 950 participants, mean ± age was 46.8 ± 9.5 years, 96% were women and 77% reported attending ≥1 Cardiopulmonary Rehabilitation session. Prior to SCAD, 49% were aerobically exercising ≥ 3times per week, and only 32% performed strength-building EX regularly. Initial and subsequent post-SCAD visit details in 299/950 participants showed that most (93%) patients received some form of EX (Figure 1-A) counseling, namely: EXP, unspecific advice or were discouraged from any EX (Figure 1-B) . Limits regarding EX type and intensity were the most common advice received among EXP group (Figure 1-C) . Conclusions: Insights from our study show that only 40% of patients were achieving current exercise recommendations for adults prior to SCAD (vs 53% adult U.S population; CDC, 2018) which suggests that SCAD patients may not be as active as previously described. Most patients receive some form of EX counseling after SCAD; however, a structured EXP is needed to avoid overly cautious approaches that could lead to uncertainty, deconditioning, impaired quality of life, or increase risks associated with a sedentary lifestyle.
