“…SCAD can manifest as angina pectoris, ACS, or even sudden cardiac death. It is now estimated that SCAD is the underlying cause of 1.7 to 4% of ACS and accounts for 0.5% of sudden cardiac deaths [3]. SCAD predominantly afflicts young to middle-aged people with few traditional risk factors for ACS.…”

Background Spontaneous coronary artery dissection (SCAD) has emerged as an increasingly diagnosed cause of ST-segment elevation myocardial infarction (STEMI), which is easily missed or delayed. The effective use of coronary angiography (CAG) and advanced intracoronary imaging examinations in STEMI patients has led to increased detection of SCAD. Case presentation A 59-year-old woman with acute angina pectoris was diagnosed with STEMI detected by electrocardiography combined with measurement of myocardial enzymes. Due to the ongoing pandemic of coronavirus disease 2019 (COVID-19) in Wuhan, she was first given thrombolytic therapy after excluding contraindications according to the requirements of the current consensus statement; however, subsequently, both the symptoms of ongoing chest pain and the electrocardiographic results indicated the failure of thrombolytic therapy, so the intervention team administered rescue percutaneous coronary intervention treatment under third-grade protection. CAG confirmed total occlusion in the distal left anterior descending (LAD) artery, with thrombolysis in myocardial infarction (TIMI) 0 flow, whereas the left circumflex and right coronary arteries appeared normal, with TIMI 3 flow. Intravenous ultrasound (IVUS) was further performed to investigate the causes of occlusion, which verified the absence of atherosclerosis but detected SCAD with intramural haematoma. During the operation, the guidewire reached the distal end of the LAD artery smoothly, the balloon was dilated slightly, and the reflow of TIMI blood could be seen by repeated CAG. During the follow-up period of one and a half years, the patient complained of occasional, slight chest tightness. The repeated CAG showed that the spontaneous dissection in the LAD artery had healed well, with TIMI 3 flow. The repeated IVUS confirmed that the SCAD and intramural haematoma had been mostly resorbed and repaired. Conclusion This was a case of failed STEMI thrombolysis in our hospital during the outbreak of COVID-19. This case indicates that doctors need to consider the cause of the disease when treating STEMI patients, especially patients without traditional cardiovascular risk factors. Moreover, CAG and intracoronary imaging examinations should be actively performed to identify the aetiology and improve the treatment success rate.

“…This meta-analysis showed that a non-invasive approach to SCAD treatment is favored for hemodynamically stable patients with NP-SCAD, which confirms the results of previous studies. Although heparin is indicated in patients with ACS, it is recommended to discontinue the anticoagulation therapy after angiographic findings of SCAD to minimize bleeding and enable intramural hematoma to organize ( 46 ).…”

“…According to the contemporary guidelines, in SCAD patients undergoing subsequent PCI, dual antiplatelet therapy (DAPT) is recommended. The duration of dual antiplatelet therapy after PCI is recommended during 12 months if patients are not on high bleeding risk ( 46 ). The optimal duration of monotherapy after 12 months in SCAD patients after PCI remains still unknown ( 46 , 47 ).…”

The optimal duration of monotherapy after 12 months in SCAD patients after PCI remains still unknown ( 46 , 47 ). The use of dual antiplatelet therapy for 12 months, in SCAD patients, was advocated after the publication of studies where in addition to hematoma, an intraluminal thrombus was frequently found on OCT ( 47 ).…”

IntroductionSpontaneous coronary artery dissection (SCAD) is a non-traumatic and non-iatrogenic separation of the coronary arterial wall.Materials and methodsThis systematic review and meta-analysis is reported following the PRISMA guidelines and is registered in the PROSPERO database. A literature search was focused on female patients in generative period (16–55 of age) with acute coronary syndrome (ACS) caused by SCAD, and comparison from that database NP-SCAD (spontaneous coronary artery dissection in non pregnant women) and P-SCAD (spontaneous coronary artery dissection in pregnant women).Results14 studies with 2,145 females in the generative period with ACS caused by SCAD were analyzed. The median age was 41 years (33.4–52.3 years). The most common risk factor was previous smoking history in 24.9% cases. The most common clinical presentation of ACS was STEMI in 47.4%. Conservative treatment was reported in 41.1%. PCI was performed in 32.7%, and 3.8% of patients had CABG surgery. LAD was the most frequently affected (50.5%). The prevalence of composite clinical outcomes including mortality, non-fatal MI and recurrent SCAD was 3.3% (95% CI: 1.4–5.1), 37.7% (95% CI: 1.9–73.4) and 15.2% (95% CI: 9.1–21.3) of patients. P-SCAD compared to NP-SCAD patients more frequently had STEMI (OR = 3.16; 95% CI: 2.30–4.34; I2 = 64%); with the left main and LAD more frequently affected [(OR = 14.34; 95% CI: 7.71–26.67; I2 = 54%) and (OR = 1.57; 95% CI: 1.06–2.32; I2 = 23%)]; P-SCAD patients more frequently underwent CABG surgery (OR = 6.29; 95% CI: 4.08–9.70; I2 = 0%). NP-SCAD compared to P-SCAD patients were more frequently treated conservatevly (OR = 0.61; 95% CI: 0.37–0.98; I2 = 0%). In P-SCAD compared to NP-SCAD mortality rates (OR = 1.13; 95% CI: 0.06–21.16; I2 = not applicable) and reccurence of coronary artery dissection (OR = 2.54; 95% CI: 0.97–6.61; I2 = 0%) were not more prevalent.ConclusionThe results of this meta-analysis indicated that patients with P-SCAD more frequently had STEMI, and events more frequently involved left main and LAD compared to NP-SCAD patients. Women with NP-SCAD were significantly more often treated conservatively compared to P-SCAD patients. P-SCAD compared to NP-SCAD patients did not have significantly higher mortality rates or recurrent coronary dissection.

This review highlights sex- and gender-specific considerations in cardiovascular diseases with a particular focus on pathophysiology, epidemiology, clinical presentation, risk factors, diagnosis, and management of spontaneous coronary artery dissection. It aims to summarize the most up to date evidence and gaps in knowledge that exist in the spontaneous coronary artery dissection space while highlighting salient points with regards to sex- and gender-based differences in clinical implications, current management, and recommended counseling practices.
