A study on the risk factors of coronary artery disease in patients with Takayasu arteritis

Impact of non-immunosuppressive medical therapy on disease progression and complications of Takayasu arteritis: A narrative review

Takayasu's arteritis is a rare large vessel vasculitis typically affecting young Asian women. It causes inflammation of the aorta and its major branches, leading to stenosis and aneurysmal dilations, and increasing cardiovascular morbidity due to accelerated atherosclerosis. Although glucocorticoids are effective for acute disease control and preliminary data on immunosuppressive drugs are promising, standardized treatment protocols are lacking. The use of prophylactic treatments with antihypertensives, antiplatelets, anticoagulants, and lipid-lowering drugs to prevent thrombotic and ischemic complications remains debated. This study reviews the evidence on the effectiveness of non-immunosuppressive medical therapy in Takayasu's arteritis. A search of the PubMed database identified eleven studies involving 204 patients. Antiplatelets: data on 68 patients were mixed, in fact low-dose aspirin did not prevent major cardiovascular events in 36 patients, but higher doses reduced ischemic complications in 24 patients. Anticoagulants: no data on new oral anticoagulants were available, and vitamin K antagonists in 9 patients did not alter cardiovascular complications. Antihypertensives: ACE-inhibitors controlled blood pressure in patients with renovascular hypertension but increased the risk of acute renal function decline, while β-blockers reduced the symptoms and the progression of myocardial hypertrophy in patients with heart failure and aortic regurgitation. Statins: data from two cohorts showed that while statins reduced the recurrence rate of arteritis in 30 patients, they did not affect recurrence rates or cardiovascular complications in 13 patients. Overall, current evidence, although not definitive, supports the use of non-immunosuppressive medical treatments to prevent long-term complications and damage in Takayasu's arteritis, considering the disease's pathophysiological mechanisms and increased cardiovascular risk. Further research is strongly encouraged.

Takayasu arteritis with recurrent coronary artery disease

Takayasu arteritis is a rare type of large vessel vasculitis that commonly affects individuals of Asian descent. Coronary artery involvement is rare. We report the case of a young female with history of Takayasu arteritis who underwent stenting and reported with in-stent restenosis. She was managed with robot-assisted coronary artery bypass grafting using bilateral internal mammary arteries.

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.

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.

A Case Report: An Elderly Male Patient With Takayasu Arteritis After Coronary Artery Bypass Grafting

Background: Takayasu arteritis is a rare chronic granulomatous inflammation involving the aorta and its main branches. In this report, we describe an extremely rare elderly male patient with Takayasu arteritis (TA) after coronary artery bypass grafting (CABG). Case Summary: A 61-year-old male patient with persistent precordial pain underwent angiography. Vascular murmurs could be heard in carotid artery and bilateral renal artery by auscultation. Laboratory parameters showed high Erythrocyte Sedimentation Rate (ESR) and C-reactive protein (CRP). CT coronary angiography showed multiple stenoses of aorta and its main branches, such as carotid and renal artery involvement. Coronary angiography showed that the coronary artery had multiple branch stenoses, the left anterior descending artery (LAD) had severe stenosis, the distal end of which was reversed to the right coronary artery (RCA), and the RCA was completely occluded. Because of the high level of markers of inflammatory activity, the patient began to take glucocorticoid. Although the patient still had multibranch stenosis of coronary artery, considering the previous CABG operation history, surgery, and interventional therapy of the patient were not feasible, the patient was given conservative drug for further treatment. After treatment, the inflammatory index was significantly descended, and N terminal-pro Brain natriuretic peptide (NT-pro BNP) was decreased. Discussion: A rare case of an elderly male patient with Takayasu arteritis after coronary artery bypass grafting was reported. In addition to hypertension, hyperlipidemia, and other risk factors, coronary artery involvement caused by TA may be a major cause of aggravation of symptoms in patients with acute myocardial infarction (AMI), especially after CABG.

The clinical features of pulmonary artery involvement in Takayasu arteritis and its relationship with ischemic heart diseases and infection

Background

Pulmonary artery involvement (PAI) in Takayasu arteritis (TAK) can lead to severe complications, but the relationship between the two has not been fully clarified.

Methods

We retrospectively investigated 166 consecutive patients with TAK who attended Kyoto University Hospital from 1997 to 2018. The demographic data, clinical symptoms and signs, comorbidities, treatments, and imaging findings were compared between patients with and without PAI. TAK was diagnosed based on the American College of Rheumatology Classification Criteria (1990) or the Japanese Clinical Diagnostic Criteria (2008). PAI was identified using enhanced computed tomography, magnetic resonance imaging, or lung scintigraphy.

Results

PAI was detected in 14.6% (n = 24) of total TAK patients. Dyspnea (25.0% vs. 8.6%; p = 0.043), pulmonary arterial hypertension (PAH) (16.7% vs. 0.0%; p < 0.001), ischemic heart disease (IHD) (29% vs. 9.3%; p = 0.018), respiratory infection (25.0% vs. 6.0%; p = 0.009), and nontuberculous mycobacteria (NTM) infection (20.8% vs. 0.8%; p < 0.001) were significantly more frequent, and renal artery stenosis (0% vs. 17%; p = 0.007) was significantly less frequent in TAK patients with PAI than in those without PAI. PAI and biologics were risk factors for NTM.

Conclusions

TAK patients with PAI more frequently have dyspnea, PAH, IHD, and respiratory infection, including NTM, than TAK patients without PAI.

Male Patients with Takayasu Arteritis and Coronary Artery Involvement are Prone to have Serious Coronary Stenosis and High Mortality

BACKGROUND

Takayasu arteritis (TAK) is a rare autoimmune vasculitis that predominantly affects the aorta and its major branches, including the coronary arteries. Limited information is available regarding sex-specific differences in coronary artery involvement among TAK patients.

OBJECTIVE

To assess the differences in coronary angiographic findings and the long-term outcomes between male and female TAK patients having coronary artery involvement.

METHODS

This retrospective cohort study included 87 TAK patients, grouped by sex, who underwent coronary angiography. General characteristics, clinical features, coronary angiographic findings, and therapeutic strategies were obtained from medical records. Major Adverse Cardiac Events (MACE), including death from any cause; myocardial infarction; repeated coronary artery revascularization; and rehospitalization due to unstable or progressive angina, or heart failure occurring during follow-up, were also recorded.

RESULTS

A total of 207 coronary lesions with stenosis were found in 87 TAK patients. The prevalence of ostial coronary lesions was lower in men than in women (9.1 vs. 23.9%, p=0.031). We observed less moderate stenosis (6.8 vs 22.7%, p=0.018) and more severe stenosis or occlusion (70.5 vs 46.0%, p=0.004) in the coronary lesions of male TAK patients. During the up to 7-year follow-up, death from any cause was greater in men than in women (21.4 vs. 1.5%, p=0.003); no other significant differences in MACE occurrence were observed between sexes.

CONCLUSIONS

Among TAK patients with coronary artery involvement, males tend to have more severe coronary stenosis and a higher risk for long-term mortality than females.
