Coronary artery involvements in Takayasu arteritis: systematic review of reports

Severe Left Main Coronary Artery Stenosis and Aortic Regurgitation in a Patient Presenting with Takayasu Arteritis

We herein report the case of a 46-year-old woman with Takayasu arteritis (TA), severe stenosis in the left main coronary artery (LMCA), and severe aortic regurgitation. Prednisolone and tacrolimus were initiated as TA treatments. Two months after initiating medical therapy, the aortic regurgitation severity improved to a moderate grade, although there was no obvious improvement in LMCA stenosis. Thus, after confirming the resolution of inflammation, we performed coronary artery bypass grafting alone without any aortic valve intervention. In TA patients with severe LMCA stenosis, surgical management of the coronary artery should therefore be considered only after successfully administering anti-inflammatory therapy.

Left Main Snorkel Stent Thrombosis in Association With Takayasu Arteritis

Takayasu arteritis (TA) is a rare form of large vessel arteritis that predominantly affects the aorta and its major branches. This inflammation leads to thickening, fibrosis, and stenosis of the arterial walls, which may lead to thrombus formation. The resulting symptoms are typically due to ischemia of the end organs. Coronary artery involvement is uncommon and primarily affects the ostia of the arteries. Ostial involvement of the coronary arteries can have a dramatic course, including fatal outcomes. We present the case of a 16-year-old female with TA involving the ostium of the left main coronary artery, causing severe stenosis. A successful percutaneous coronary intervention was performed on the left main artery with snorkel stent placement, which was complicated by cardiac arrest seven months later due to complete thrombosis of the proximal opening of the protruding stent.

Coronary artery lesions in Takayasu arteritis

Introduction

Takayasu arteritis (TAK) is a granulomatous inflammation of vessels of large diameter, mainly affecting the aorta and its proximal branches, which is more common in young women. The incidence of coronary artery disease in TAK is unknown and not sufficiently studied.

Material and methods

A literature review was performed for the period 2003 to 2023 using a search of the PubMed and Scopus scientific databases. We used the following key words to search the academic journal databases: "Takayasu arteritis", "coronary angiography", "myocardial revascularization", "coronary artery disease", "angina pectoris", and "myocardial infarction".

Results

The analysis of studies showed that coronary artery lesions (CAL) in TAK are not uncommon, being identified particularly in children and young individuals. Pathology of the coronary arteries increases the morbidity and mortality of TAK patients. In TAK, the ostia and proximal segments of the coronary arteries are more frequently affected, presenting as stenosis or occlusion with the development of stable coronary artery disease, unstable coronary artery disease, acute myocardial infarction, and sudden death. The diagnosis of TAK and coronary artery pathology is often complicated due to nonspecific manifestations and frequently the absence of symptoms. The treatment of patients with TAK with CAL is challenging and requires both pharmacological therapy and interventional or surgical methods of myocardial revascularization.

Conclusions

Takayasu arteritis is a more prevalent cause of CAL development, especially in young patients, than previously believed, and cardiovascular death due to CAL is not rare. Early diagnosis of TAK with CAL, particularly occlusion or hemodynamically significant stenosis, and the prompt initiation of appropriate treatment prevent dangerous complications, reduce mortality, and improve prognosis.

Accelerated Atherosclerosis and Management of Cardiovascular Risk in Autoimmune Rheumatic Diseases: An Updated Review

Even though diagnosis and management pathways have been substantially improved over the last years, autoimmune rheumatic diseases (AIRDs) such as rheumatoid arthritis, systemic sclerosis, systemic lupus erythematosus, antiphospholipid syndrome, Sjögren's syndrome, and systemic vasculitides have been linked to elevated rates of cardiovascular morbidity and mortality, primarily secondary to accelerated atherosclerosis. This phenomenon can be partially attributed to the presence of established cardiovascular risk factors but may also be a result of other inflammatory and autoimmune mechanisms that are enhanced in AIRDs. According to the current guidelines, the recommendations regarding cardiovascular disease prevention in patients with AIRDs are not significantly different from those applied to the general population. Herein, we present a review of the current literature on the risk of accelerated atherosclerosis in AIRDs and provide a summary of available recommendations for the management of cardiovascular risk in rheumatic diseases.

Refractory Takayasu's Arteritis with Severe Coronary Involvement-Case Report and Literature Review

This report presents the case of a female patient diagnosed with Takayasu arteritis from childhood, with severe, refractory coronary involvement, leading to two acute coronary syndromes and multiple anginous episodes. Consequently, the patient suffered aorto-bicarotid bypass two times, multiple interventional procedures with stent implantation, balloon angioplasty, and up to ten repeated in-stent restenosis that required reinterventions, despite being on maximal immunosuppressive treatment. In recent years, various studies have been reported that aim to best characterize this particular type of vascular damage and to indicate optimal therapeutic options for treatment. The latter should be based on the activity of the underlying disease; however, no reliable markers are available in TA. The management of TA patients with coronary involvement continues to be a challenge and requires both drug and interventional techniques to avoid life-threatening events.

Monocyte-to-high-density lipoprotein ratio as a predictor for patients with Takayasu arteritis and coronary involvement: a double-center, observational study

Background

The implication of the monocyte-to-high-density lipoprotein ratio (MHR) in Takayasu arteritis (TAK) remains unclear.

Objective

We aimed to assess the predictive value of the MHR to identify coronary involvement with TAK and determine the patient prognosis.

Methods

In this retrospective study, 1,184 consecutive patients with TAK were collected and assessed, and those who were initially treated and with coronary angiography were enrolled and classified according to coronary involvement or no involvement. Binary logistic analysis was performed to assess coronary involvement risk factors. Receiver-operating characteristic analysis was used to determine the MHR value to predict coronary involvement in TAK. Major adverse cardiovascular events (MACEs) were recorded in patients with TAK and coronary involvement within a 1-year follow-up, and Kaplan-Meier survival curve analysis was conducted to compare MACEs between them stratified by the MHR.

Results

A total of 115 patients with TAK were included in this study, and 41 of them had coronary involvement. A higher MHR was found for TAK with coronary involvement than for TAK without coronary involvement (P = 0.014). Multivariate analysis showed that the MHR is an independent risk factor for coronary involvement in TAK (odds ratio: 92.718, 95% confidence interval (CI): 2.813-3056.291, P = 0.011). With the best cut-off value of 0.35, the MHR identified coronary involvement with 53.7% sensitivity and 68.9% specificity [area under the curve (AUC): 0.639, 95% CI: 0.544-0.726, P=0.010] and identified left main disease and/or three-vessel disease (LMD/3VD) with 70.6% sensitivity and 66.3% specificity (AUC: 0.704, 95% CI: 0.612-0.786, P = 0.003) in TAK. Combined with other variables, the MHR identified coronary involvement with 63.4% sensitivity and 90.5% specificity (AUC: 0.852, 95% CI: 0.773-0.911, P < 0.001), and identified LMD/3VD with 82.4% sensitivity and 78.6% specificity (AUC: 0.827, 95% CI: 0.720-0.934, P < 0.001) in TAK. A total of 39 patients with TAK and coronary involvement were followed up for 1 year, and 5 patients suffered a MACE. Those with an MHR >0.35 had a higher MACE incidence than their counterparts with an MHR ≤0.35 (χ² = 4.757, P = 0.029).

Conclusions

The MHR could be a simple, practical biomarker for identifying coronary involvement and LMD/3VD in TAK and predicting a long-term prognosis.

Operative experience on descending aorta with Takayasu Arteritis: a review

Patients with Takayasu arteritis (TA) and descending aorta involvement often experience insidious onset and slow progression, leading to irreversible vascular lesions despite medication therapy. Surgical management plays a crucial role in resolving hemodynamic disturbances and has shown promise in improving the outcomes of this patient population, owing to significant advancements in surgical expertise. However, studies focusing on this rare disease are lacking. This review summarizes the characteristics of patients with stenosis in descending aorta, emphasizing surgical approaches, perioperative management, and disease outcomes. The operative approach depends on lesion location and extent. Existing studies have confirmed that the choice of surgical modality significantly influences postoperative complications and long-term prognosis in patients, highlighting the effectiveness of bypass surgery as a favorable option in clinical practice with a satisfactory long-term patency rate. To mitigate postoperative complications, it is advisable to conduct regular imaging follow-ups to prevent the deterioration of the condition. Notably, the occurrence of restenosis and pseudoaneurysm formation deserves particular attention due to their impact on patient survival. The use of perioperative medication remains a topic of debate, as previous studies have presented divergent perspectives. The primary objective of this review is to provide a comprehensive perspective on surgical treatment and offer customized surgical approaches for patients in this population.

Clinical characteristics and risk factors of coronary artery lesions in chinese pediatric Takayasu arteritis patients: a retrospective study

BACKGROUD

To summarize the clinical characteristics and identify the risk factors for pediatric Takayasu arteritis (TAK) with coronary artery lesions (CALs).

METHODS

Clinical data of pediatric TAK patients in our center were retrospectively assessed. Independent risk factors for CALs were identified using multivariate logistic regression analysis. Survival analysis was used to compare differences in survival rates between the groups.

RESULTS

Among the 66 pediatric TAK cases, the incidence of accompanying CALs was 39.4%. In the CAL group, 19 (73.1%) cases started within 36 months. None of the patients had symptoms of angina or ischemia on electrocardiogram (ECG), the CALs were detected using coronary ultrasound. The CALs most commonly were the left main and right coronary arteries. The lesions were mostly small or middle coronary artery aneurysms; some children may have giant coronary aneurysmal dilations, thrombosis and heart failure. The age of onset and symptom onset to diagnosis in TAK patients with CAL were lower than those in TAK patients without CAL(P < 0.005). TAK patients with CAL had significantly higher CRP,WBC, PLT,TNF-α and IL-2R levels (P < 0.05), lower HGB (P = 0.01), lower rate of renal artery stenosis (RAS) (P = 0.009). In multivariate logistic regression, the risk factors for pediatric TAK combined with CAL included the age of TAK onset (OR = 0.9835, 95% CI: 0.9710-0.9946, P = 0.006) and RAS (OR = 0.1901, 95% CI: 0.0386-0.7503, P = 0.03). In addition, there was no significant difference in survival rates between the two groups after regular treatment.

CONCLUSION

This study showed that the occurrence of CAL in pediatric TAK patients has a relatively more rapid clinical course, and a stronger inflammatory state at the time of diagnosis. The earlier the age of TAK onset and without RAS are more likely to cause CAL.

Clinical and vascular lesion characteristics of the patients with takayasu arteritis manifested firstly as acute myocardial infarction at onset

Objective

To explore clinical and vascular lesion characteristics of the patients with Takayasu arteritis (TA) manifested firstly as acute myocardial infarction (AMI) at onset and to improve the diagnostic rate of TA.

Methods

The clinical and angiographic data of six patients with TA manifested firstly as AMI at onset were retrospectively analyzed.

Results

Of six patients (16-25 years old), 83.33% (five cases) was female, three patients had a history of hypertension and three patients did not have any medical history. One patient had intermittent effort chest tightness. On admission patients all presented with chest pain, dyspnea, hypotension, cardiogenic shock, abnormal electrocardiogram, and elevated cardiac troponin I. The vessel involvement was left coronary main trunk 83.33%, left anterior descending artery 33.33% and left circumflex branch 16.67%, right coronary artery 66.67%, subclavian artery 83.33%, and renal artery 50%. Five patients received the emergency PCI. One patient died of heart failure. During follow-up 3 patients received again PCI treatment.

Conclusion

Clinical and vascular lesion characteristics of those patients were no discomfort before admission, and the suddenly typical manifestation of AMI. Severe stenosis or occlusion occurred in main coronary artery ostia and peripheral large artery. For the TA patients with hemodynamic instability the effectiveness of emergency PCI is positive.

The Treatment Dilemma of Arteriopathy in Takayasu Arteritis- A State-of-the-Art Approach

Takayasu Arteritis (TA) is a chronic idiopathic granulomatous pan-arteritis affecting the pulmonary artery, the aorta, and its principal derived branches. The majority of TA patients are female (82.9-97.0 percent). Due to the inflammatory character of the illness, arterial stenosis therapy must be treated differently than the atherosclerosis process. In this review paper, we outline a strategy using real-world challenging cases.

Risk factors of avascular necrosis in Takayasu arteritis: a cross sectional study

Takayasu arteritis (TA) is a large-cell vasculitis, and is not usually associated with avascular necrosis (AVN). The objective of the study was to investigate any association between TA and AVN, including the possible pathogenic effect of glucocorticoid (GCs) use. The study design was retrospective and cross sectional. TA patients were enrolled in the study. Demographic variables, disease activity, treatments, physician global assessment, Indian Takayasu Clinical activity score 2010, and Kerr criteria were recorded. Logistic regression analysis was performed to identify predictors of AVN. A total of 29 patients were assessed. AVN was observed in four (13.8%) patients with TA. Male gender and elevated C-reactive protein (CRP) were found to be significantly associated with AVN (p = 0.001 and p = 0.006, respectively). While type IIb TA was more common in patients with AVN (n = 2, 50%), type V was more likely in the absence of AVN (n = 13, 52%). Descending aorta and thoracic aorta were usually involved in patients with AVN (both, n = 3, 75%). In multivariate logistic regression, increased CRP levels were the only predictor for AVN (OR = 1.183, 95% Cl = 1.025-1.364, p = 0.021). No association was identified between AVN in TA patients and either duration or cumulative dose of GCs. The present study found that higher CRP levels and male gender were associated with AVN in patients with TA.
