Recurrent spontaneous coronary artery dissection

Online information for spontaneous coronary artery dissection (SCAD) survivors and their families: A systematic appraisal of content and quality of websites

BACKGROUND

Spontaneous coronary artery dissection (SCAD) survivors often seek information online. However, the quality and content of websites for SCAD survivors is uncertain. This review aimed to systematically identify and appraise websites for SCAD survivors.

METHODS

A systematic review approach was adapted for websites. A comprehensive search of SCAD key-phrases was performed using an internet search engine during January 2023. Websites targeting SCAD survivors were included. Websites were appraised for quality using Quality Component Scoring System (QCSS) and Health Related Website Evaluation Form (HRWEF), suitability using the Suitability Assessment Method (SAM), readability using a readability generator, and interactivity. Content was appraised using a tool based on SCAD international consensus literature. Raw scores from tools were concerted to percentages, then classified variably as excellent through to poor.

RESULTS

A total of 50 websites were identified and included from 600 screened. Overall, content accuracy/scope (53.3 ± 23.3) and interactivity (67.1 ± 11.5) were poor, quality was fair (59.1 ± 22.3, QCSS) and average (83.1 ± 5.8, HRWEF) and suitability was adequate (54.9 ± 13.8, SAM). The mean readability grade was 11.6 (±2.3), far exceeding the recommendations of ≤ 8. By website type, survivor affiliated and medically peer-reviewed health information websites scored highest. Appraisal tools had limitations, such as overlapping appraisal of similar things and less relevant items due to internet modernity.

CONCLUSION

Many online websites are available for SCAD survivors, but often have limited and/or inaccurate content, poor quality, are not tailored to the demographic, and are difficult to read. Appraisal tools for health website require consolidation and further development.

Spontaneous Coronary Artery Dissection Across the Health Care Pathway: A National, Multicenter, Patient-Informed Investigation

BACKGROUND

Clinical practice guidelines for the management and convalescence of patients with spontaneous coronary artery dissection (SCAD) have yet to be developed. The targeted content, delivery, and outcomes of interventions that benefit this population remain unclear. Patient-informed data are required to substantiate observational research and provide evidence to inform and standardize clinical activities.

METHODS AND RESULTS

Patients diagnosed with SCAD (N=89; 86.5% women; mean age, 53.2 years) were purposively selected from 5 large tertiary care hospitals. Patients completed sociodemographic and medical questionnaires and participated in an interview using a patient-piloted semistructured interview guide. Interviews were transcribed and subjected to framework analysis using inductive and then deductive coding techniques. Approximately 1500 standard transcribed pages of interview data were collected. Emotional distress was the most commonly cited precipitating factor (56%), with an emphasis on anxiety symptoms. The awareness and detection of SCAD as a cardiac event was low among patients (35%) and perceived to be moderate among health care providers (55%). Health care providers' communication of the prognosis and self-management of SCAD were perceived to be poor (79%). Postevent psychological disorders among patients were evident (30%), and 73% feared recurrence. Short- and longer-term follow-up that was tailored to patients' needs was desired (72%). Secondary prevention programming was recommended, but there were low completion rates of conventional cardiac rehabilitation (48%), and current programming was deemed inadequate.

CONCLUSIONS

This early-stage, pretrial research has important implications for the acute and long-term management of patients with SCAD. Additional work is required to validate the hypotheses generated from this patient-oriented research.

Current challenges in treatment and management of spontaneous coronary artery dissection

Though an infrequent cause of acute coronary syndrome, spontaneous coronary artery dissection is an increasingly recognized cardiovascular condition predominantly seen in middle-aged females. Its pathophysiology is defined by separation of coronary arterial wall layers which cause acute coronary syndrome-like presentations with relatively high recurrence rates. Overall, there is a lack of reported literature and understanding of the short- and long-term management for spontaneous coronary artery dissection. Therapeutic approaches include, but are not limited to, percutaneous coronary intervention, surgical revascularization, antithrombotic therapy, and beta-blocker therapy. There is a significant absence of randomized control trials to help guide both interventional and medical management for spontaneous coronary artery dissection. This review is aimed to review the current literature regarding risk factors and considerations for the short- and long-term management of spontaneous coronary artery dissection.

Factors associated with recurrent spontaneous coronary artery dissection: a systematic review and meta-analysis

BACKGROUND

The risk of recurrent spontaneous coronary artery dissection (SCAD) is a major concern to SCAD patients and clinicians. Identifying the high-risk subsets of recurrent SCAD remains an ongoing challenge. The meta-analysis aimed to assess the potential predictors for SCAD recurrence.

METHODS

A literature search was performed in PubMed to collect studies that assessed potential factors associated with recurrence of SCAD among angiographically confirmed SCAD patients, including pregnancy, ventricular arrhythmia at presentation, history of hypertension, migraine, fibromuscular dysplasia (FMD), extracoronary vascular abnormalities (EVA), recent emotional or physical stress, and use of thienopyridine, beta-blocker, or statin. A meta-analytic approach was employed to estimate the relative risk (RR) with a 95% confidence interval (CI) by fitting random-effects models using the generic inverse variance weighted method.

RESULTS

A total of 14 studies representing 4206 SCAD patients were included. Hypertension (RR, 1.49; 95% CI, 1.05-2.12; P = 0.0247) and FMD (RR, 2.02; 95% CI, 1.03-3.94; P = 0.0404) were associated with a greater risk of SCAD recurrence. The use of beta-blocker (RR, 0.51; 95% CI, 0.33-0.77; P = 0.0013) was associated with a lower risk of SCAD recurrence. Pregnancy, ventricular arrhythmia at presentation, migraine, EVA, recent emotional or physical stress, and use of thienopyridine or statin were not significantly associated with recurrent SCAD (P > 0.05).

CONCLUSION

SCAD patients with hypertension or FMD were at a higher risk of recurrence, whereas beta-blocker usage was related to a reduced risk. These findings may provide insights into risk prediction and management after the SCAD episode.
