Clinical Presentations

Spontaneous Coronary Artery Dissection (SCAD) is an important cause of myocardial infarction that typically affects women without traditional cardiovascular risk factors. It is the most common cause of myocardial infarction in pregnant and postpartum women. SCAD is often underdiagnosed due to the lack of clinician familiarity, and patients with pregnancy-associated SCAD often have more severe clinical presentations than those without. We present a case of SCAD in a multiparous woman who presented with acute chest pain in the postpartum period.

Abstract Aims  Spontaneous coronary artery dissection (SCAD) diagnosis is challenging as angiographic findings are often subtle and differ from coronary atherosclerosis. Herein, we describe characteristics of patients with acute myocardial infarction (MI) caused by first septal perforator (S1) SCAD. Methods and results  Patients were gathered from SCAD registries at Minneapolis Heart Institute and Vancouver General Hospital. First septal perforator SCAD prevalence was 11 of 1490 (0.7%). Among 11 patients, age range was 38–64 years, 9 (82%) were female. Each presented with acute chest pain, troponin elevation, and non-ST-elevation MI diagnosis. Initial electrocardiogram demonstrated ischaemia in 5 (45%); septal wall motion abnormality was present in 4 (36%). Angiographic type 2 SCAD was present in 7 (64%) patients with S1 TIMI 3 flow in 7 (64%) and TIMI 0 flow in 2 (18%). Initial angiographic interpretation failed to recognize S1-SCAD in 6 (55%) patients (no culprit, n = 5, septal embolism, n = 1). First septal perforator SCAD diagnosis was established by review of initial coronary angiogram consequent to cardiovascular magnetic resonance (CMR) demonstrating focal septal late gadolinium enhancement with corresponding oedema (n = 3), occurrence of subsequent SCAD event (n = 2), or second angiogram showing healed S1-SCAD (n = 1). Patients were treated conservatively, each with ejection fraction >50%. Conclusion  First septal perforator SCAD events may be overlooked at initial angiography and mis-diagnosed as ‘no culprit’ MI. First septal perforator SCAD prevalence is likely greater than reported herein and dependent on local expertise and availability of CMR imaging. Spontaneous coronary artery dissection events may occur in intra-myocardial coronary arteries, approaching the resolution limits of invasive coronary angiography.

Life Threatening

A healthy 17-year-old boy was admitted to the emergency department presenting with a pressure-like sternal pain that started during exercise. His physical examination was normal. Twelve-lead ECG and transthoracic echocardiogram suggested a myocardial infarction. The patient was submitted to an invasive coronary angiography, which revealed a distal occlusion of the left anterior descending artery, due to a spontaneous coronary artery dissection. A balloon angioplasty was performed, with good results. Aetiological study did not discover any pathologic condition. Chest pain in paediatric age is a frequent complaint, despite not being usually caused by a serious condition. However, it is important to remember warning signs in order to diagnose life-threatening diseases, as soon as possible.

Spontaneous Dissection

Spontaneous coronary artery dissection is a rather rare cause of myocardial infarction, chest pain, and sudden death.There are currently no known direct causes of this condition.Most of the reported dissections have occurred in the left anterior descending coronary artery.Herein, we report the case of a 58-year-old woman who presented at our institution with an acute ST-elevation myocardial infarction secondary to a spontaneous dissection of the right coronary artery. Primary PCIresolved the occlusion of the artery, and the patient was discharged from the hospital on medical therapy.University Heart Journal Vol. 12, No. 2, July 2016; 105-107

Introduction: Spontaneous coronary artery dissection (SCAD) is one of the most common non-atherosclerotic causes of myocardial infarction (MI) in young patients, yet little is known about post-discharge outcomes. Given the high psychological stress of a SCAD diagnosis, we sought to understand the rehospitalization burden after SCAD so as to provide more prognostic data to SCAD patients. Methods: Using data from the Nationwide Readmission Database 2010-16, we identified patients 18-55 years of age hospitalized with MI with and without SCAD. We compared readmission over 1 year after index hospitalization for all-cause, MI, chest pain without MI, and heart failure. Cox proportional regression was used to examine factors associated with readmission, and we explored interactions of patient factors*SCAD to identify factors associated with differential risk of readmission in patients with SCAD. Results: Among 327,227 young patients admitted with an MI, 3704 (1.1%) had a diagnosis of SCAD. Patients with SCAD were more likely to be younger, women, have a higher burden of anxiety or depression, and longer length of stay compared with those without SCAD. While the risk of all-cause rehospitalization over 1 year was similar in those with versus without SCAD (KM-estimated rates: 22.3% vs. 24.1%; log-rank p=0.596, Figure), patients with SCAD were more likely to be rehospitalized for MI (4.9% vs. 4.2%, log-rank p=0.012) and chest pain without MI (3.6% vs. 2.8%, log-rank p=0.060) but less likely to be rehospitalized for heart failure (1.0 % vs. 1.8%, log-rank p=0.005). In the multivariable model, a diagnosis of SCAD was not associated with risk of rehospitalization (HR 1.00, 95% CI 0.92-1.08) nor was a diagnosis of SCAD associated with a differential effect of any of the patient factors on the risk of rehospitalization (all interaction p-values >0.05). Conclusion: Although patients with SCAD had a similar risk of rehospitalization compared with young patients with MI but without SCAD, we identified different patterns of hospitalization, which may be explained by the different underlying conditions. Further studies are needed to investigate possible interventions to reduce the high burden of post-SCAD rehospitalizations.

Abstract Background  Acute myocardial infarction in pregnancy is occasionally due to spontaneous coronary artery dissection (SCAD). Although uncommon, the majority of cases of pregnancy-associated SCAD (pSCAD) has critical presentations with more profound defects that portend high maternal and foetal mortality, and frequently necessitate preterm delivery. This is a case of pSCAD with ongoing ischaemia that required temporary mechanical circulatory support (MCS) and emergent revascularization, while the pregnancy was successfully continued to early-term. Case summary  A 30-year-old woman G2P1 at Week 32 of gestation with no medical history, presented to the emergency department with severe chest pain. An electrocardiogram showed ST-segment elevation in the anterolateral leads. An emergent cardiac catheterization revealed dissection of the proximal left anterior descending (LAD) artery with TIMI (thrombolysis in myocardial infarction) 3 flow. Although initially stable, she later experienced recurrent chest pain and developed cardiogenic shock, necessitating MCS, and emergent revascularization. She was stabilized and remained closely monitored in the hospital prior to vaginal delivery at early-term. Discussion  This case of pSCAD at Week 32 of gestation complicated by refractory ischaemia illustrates the complexity of management, which requires a multi-disciplinary team to reduce both maternal and foetal mortality. Conservative management of SCAD, while preferred, is not always possible in the setting of ongoing ischaemia, particularly if complicated by cardiogenic shock. A thorough weighing of risks vs. benefits and ongoing discussions among multiple subspecialists in this case allowed for the stabilization of the patient and subsequent successful early-term delivery.

Abstract Background Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial infarction (MI) in young to middle-aged women. However, the role of revascularization for SCAD, especially percutaneous coronary intervention (PCI), remains controversial. Purpose To compare revascularization strategies and outcomes in SCAD patients presenting with ST-elevation MI (STEMI) vs. unstable angina or non-STEMI (UA/NSTEMI). Methods We analyzed SCAD patients who presented acutely between June 2014 and June 2018 to 22 centers participating in the Canadian SCAD Cohort Study. We compared treatment patterns and clinical outcomes in SCAD patients with an initial clinical presentation of STEMI vs. UA/NSTEMI. We assessed follow-up major adverse cardiovascular event (MACE) rate, a composite of all-cause death, MI, and stroke. The impact of revascularization on MACE was also evaluated according to clinical presentations (STEMI vs. UA/NSTEMI). Results Among 750 SCAD patients (mean age 51.7±10.5 years; 88.5% were women), 234 (31.2%) presented with STEMI. In the STEMI group, left anterior descending artery was more commonly involved (62.0% vs. 47.5%, p<0.001) and TIMI 0 flow was more frequently observed (24.8% vs. 7.2%, p<0.001). A total of 27.8% of STEMI patients were treated with revascularization (98.5% PCI), whereas only 8.7% of UA/NSTEMI patients were revascularized (93.3% PCI). For STEMI patients, 93.9% were planned procedures, whereas, for UA/NSTEMI patients, 71.1% were planned revascularization. Successful or partially successful PCI was 65.5% for STEMI and 76.9% for UA/NSTEMI (p<0.001). The median follow-up period was 850 (interquartile range: 619–1096) days. MACE rate was not different between STEMI and UA/NSTEMI (UA/NSTEMI as a reference: hazard ratio [HR] 1.08, 95% confidence interval [CI] 0.70–1.68, p=0.72). Regardless of clinical presentations, revascularization was associated with increased risk of MACE (STEMI: HR 2.57, CI 1.25–5.25, p=0.01; UA/NSTEMI: HR 5.41, CI 3.19–9.19, p<0.001). The association of revascularization and increased risk of MACE was more prominent in UA/NSTEMI than in STEMI (Figure), but it did not reach statistical significant (P for interaction = 0.09). Conclusions In SCAD patients, long-term clinical outcome was not different between STEMI and UA/NSTEMI presentations. Revascularization was more frequently performed with STEMI; however, regardless of clinical presentations, revascularization was associated with worse clinical outcomes. Careful patient selection for revascularization is key for SCAD patients and further studies are needed to clarify selection criteria.

Abstract Aims We present the case of a 25 years-old patient, presented to the Emergency Department for chest pain and epigastralgia complicated by vomiting. Symptoms started about 30 h before, afterwards an effort. The patient did not have any known cardiovascular risk factors (except for sporadic consumption of cannabis) and family medical history was negative for premature cardiovascular disease or sudden cardiac death. His past medical history was unremarkable. Methods and results Clinical examination was normal. ECG was suggestive for subacute anterior ST-elevation myocardial infarction (QS in V1–V4 leads with ST segment elevation and biphasic T-waves in V4–V6) and was accompanied by significant elevation of myocardial necrosis biomarkers (hsTnT 3416 ng/l, n.v. <15). Echocardiography revealed a severely reduced left ventricular ejection fraction (LVEF = 30%) with regional wall motion abnormalities (apical and septal akinesia, and anterior mid-ventricular segment hypokinesia). Coronary angiography was suggestive for a dissection of the proximal-to-mid left anterior descending artery. Dissection flap, subocclusion of the first septal branch, and intramural thrombosis were noted. Direct stenting with drug-eluting stent was successful, with thrombolysis in myocardial infarction (TIMI) flow grade 3. The patient was started on dual antiplatelet treatment (aspirin and ticagrelor), ACE-inhibitors, beta blockers, and spironolactone. Further testing ruled out other conditions that may be associated with spontaneous coronary artery dissection (autoimmune diseases, including vasculitis, connective tissue disease, coagulative disorders). The clinical course was complicated by pericarditis and the development of LV apical thrombus. So, patient was started on anticoagulation (warfarin) with subsequently downgrading from ticagrelor to clopidogrel. Echocardiographic follow-up documented a progressive improvement of LVEF (50%), and global longitudinal strain (GLS −15%) with persistence of wall motion abnormalities in the apical and septal segments. Partial resolution of intracavitary thrombi was documented. CMR revealed LV apical aneurysm. Moreover, the use of dedicated sequences showed transmural late gadolinium enhancement in akinetic segments, and fatty metaplasia of the apical portion of the anterior wall and anterior septal wall. Finally, early gadolinium enhancement imaging, confirmed the persistence of LV stratified apical thrombus. Conclusions Spontaneous coronary artery dissection (SCAD) is an underdiagnosed and frequent cause of acute coronary syndrome (ACS) in young-to-middle aged patients, particularly women; therefore, even in young people, a chest pain episode suggestive for an ischaemic cause should never be underestimated. Cardiac magnetic resonance is the most accurate method to evaluate the sequelae of myocardial infarction (including LV size and function, presence of fatty metaplasia, extent and transmurality of ischaemic scar, presence of thrombi), to aid in differential diagnosis and to define prognosis and guide the therapeutic management.

A 25-year-old previously healthy male presented to our emergency room with acute chest pain and ventricular arrhythmia-related cardiac arrest. ST elevation myocardial infarction was diagnosed and coronary angiography revealed diffuse critical narrowing from the proximal to the distal left anterior descending artery. Diffuse intramural hematoma was demonstrated on intravascular ultrasound. Two stents were placed to cover the whole dissection length and flow was successfully restored. Spontaneous coronary artery dissection can be a fatal event and could be mistaken for atherosclerotic plaque or coronary spasm rather than luminal compression on coronary angiography and intravascular imaging is helpful in this condition.
