Introduction: Spontaneous coronary artery dissection (SCAD) is a non-atherosclerotic cause of ACS that preferentially impacts young women. Increasing evidence suggests that patients with SCAD do well with a conservative approach, as intramural hematoma frequently resolves with medical management and complications from PCI are common. Our objective is to describe changes in management of SCAD over time at the University of Pennsylvania Health System (UPHS). Methods: We conducted a retrospective cohort study among patients treated within UPHS from 2005-2019. We identified all patients in the electronic health record with SCAD using ICD-9 (414.12) and ICD-10 (I25.42) codes. Charts were manually reviewed and indexed by date of SCAD event. Time categories were calculated by tertiles of patients. Since the first tertile spanned 21 years, this category was subdivided. The most recent time period represents practice after the AHA Scientific Statement on SCAD was published. Cochran-Armitage trend tests compared trends over time. Results: We identified 140 patients with SCAD. In this cohort, 43% of patients treated from 1993-2005 were managed conservatively, compared to 89% of patients treated in 2018-2019, while 57% of patients treated from 1993-2005 were managed invasively, compared to 11% of patients treated in 2018-2019, p<0.001 for trend over time (Figure). Between 1993-2005 and 2018-2019, the use of DAPT increased from 40% to 80% (p<0.001 for trend) and use of statins increased from 60% to 85% (p=0.021 for trend). Beta blocker use remained stable (80% vs. 89%, p=0.401) and ACEi/ARB use varied considerably without a clear trend over time (p=0.553). Conclusions: The proportion of patients with SCAD managed conservatively has steadily increased since 2015. This trend corresponds to the increased understanding of clinical outcomes of this patient population. Medical treatment has changed over time and most patients are treated with DAPT, statins, and beta blockers.

Introduction: Spontaneous coronary artery dissection (SCAD) is commonly associated with fibromuscular dysplasia (FMD), a vascular condition that can lead to aneurysm and dissection in any arterial bed. SCAD and FMD are increasingly being diagnosed, especially in women. Our objective is to describe screening patterns of FMD over time among patients with SCAD. Methods: We conducted a retrospective cohort study, identifying patients treated for SCAD in the University of Pennsylvania Health System from 2005-2019 using ICD-9 (414.12) and ICD-10 (I25.42) codes. Charts were manually reviewed and clinical data were abstracted. Screening modalities included CT angiogram (CTA) or MR angiogram (MRA) of the head, neck, or abdomen; carotid or renovascular ultrasound; or renal angiography. Complete screening was defined as having head, neck, and abdominal imaging. We indexed cases by date of SCAD event. Time categories were calculated by quartiles of patients. We used Fisher’s exact test to compare proportions and Cochran-Armitage trend test to compare trends over time. Results: We identified 121 patients with SCAD with ≥ 6 months of follow-up prior to the COVID-19 pandemic. FMD screening rates by any modality were higher among patients with SCAD in 2018-2019 compared to 1993-2011 (62% vs. 28%, p=0.009 for trend), see Figure. Rates of complete screening remained low and did not change over time (p=0.451 for trend). In 2018-2019, only 41% of patients were screened with CTA or MRA of the abdomen, 26% with CTA or MRA of the neck, and 15% with CTA or MRA of the head. Patients undergoing complete screening had higher rates of FMD diagnosis compared to those undergoing any screening (63% vs. 37%, p=0.036). Conclusions: While overall FMD screening in SCAD patients has increased, complete screening rates remain low. FMD was diagnosed more often in patients undergoing complete screening, highlighting the importance of head, neck, and abdominal imaging in all patients with SCAD.

Abstract Background Spontaneous Coronary Artery Dissection (SCAD) is an important cause of acute coronary syndrome particularly in young-middle aged women. Revascularisation is challenging due to an underlying disrupted and friable coronary vessel wall leading to widely reported worse outcomes than for atherosclerotic coronary disease. Therefore, a conservative approach where possible is favoured however in some cases haemodynamic instability, ongoing ischaemia and reduced distal flow mandates consideration of revascularisation. Purpose To compare SCAD survivors managed with PCI or conservatively in terms of presentation characteristics, complications and long-term outcomes. Methodology and results 226 angiographically confirmed SCAD survivors (95% female,47±9.7yrs) who underwent PCI were compared in a case control study with two hundred and twenty-five angiographically confirmed SCAD survivors (92% female, 49±9.9yrs) who were conservatively managed. Patients were recruited from UK, Spanish and Dutch SCAD registries and both groups were well matched in terms of baseline demographics. Those treated with PCI were more likely to present with proximal SCAD (30.8% vs 7.6% P&lt;0.01) and ST elevation myocardial infarction (STEMI) or cardiac arrest with reduced flow (32.3% vs 6.3% P&lt;0.01). Intervention was performed with stents in 72.4%, plain old balloon angioplasty in 21.1% and wiring in 6.4% of cases and more often for multi-segment disease (40.8% vs 26.3% P&lt;0.01). In cases with initial reduced flow undergoing PCI an improvement in flow was seen in 83%. Analysis of UK PCI cases (n=144) reveal complications in 56 (38.8%). However, when assessed for significance defined by a reduction in flow in a proximal/mid vessel, stent extension into left main stem, iatrogenic dissection requiring PCI and CABG as a consequence of PCI only 13 cases (9%) met criteria. Iatrogenic dissection accounts for the majority (76.9%). SCAD lesion length was associated with presence of complications (P=0.025). There was a non-significant trend towards major adverse cardiovascular events (MACE) occurring more frequently in those undergoing PCI (18% vs 11% P=0.067) driven by revascularisation (5% vs 1% P=0.036). Median follow up was 2.7 years. Conclusions PCI in SCAD is often performed in higher risk patients; in those presenting with reduced flow, the majority demonstrate improvement. Importantly whilst overall complication rates were similar to those widely reported, clinically significant complications were low. Multivariate modelling will reveal factors associated with complications to aid future decision making in this challenging patient group.
