Assessment of aortic stiffness and ventricular diastolic functions in patients with Behçet’s disease

Arterial Stiffness and Adult Onset Vasculitis: A Systematic Review

Chronic inflammation represents the cornerstone of the raised cardiovascular (CV) risk in patients with inflammatory rheumatic diseases (IRD), including vasculitis. Standardized mortality ratios in these patients are higher as compared to the general population, and the excess of premature mortality is due to early atherosclerotic events. Thus, IRD patients need appropriate CV risk assessment and management according to this CV disease (CVD) burden. Adequate control of CV risk is still lacking in usual care, but early diagnosis of silent and subclinical CVD is crucial to improve the long-term prognosis of these patients. Increased arterial stiffness may provide a pathophysiological link between inflammation and increased cardiovascular risk. Several noninvasive methods are now available to estimate artery stiffness in the clinical setting, including pulse wave velocity assessment. The independent predictive value of arterial stiffness for cardiovascular events has been demonstrated in general as well as in selected populations, and reference values adjusted for age and blood pressure have been suggested. Thus, arterial stiffness is an interesting biomarker for cardiovascular risk stratification. This systematic review summarizes the additional value that PWV measurement can provide in the setting of vasculitis, with a focus in the different clinical stages and CV risk prevention. This systematic review is registered with registration number: Prospero CRD42021259603.

The pattern of cardiovascular manifestations in Egyptian Behçet’s patients and its relation to disease activity

Background

Behçet’s disease (BD) is also referred to as vascular BD when it frequently involves the heart and vessels. This study aimed to describe the cardiovascular manifestations in patients with BD and its correlation to disease activity. We conducted a cross-sectional study on 40 patients diagnosed with BD according to the International Criteria for Behçet’s Disease 2014. All the patients were subjected to detailed history taking, full clinical examination, lab investigations, resting electrocardiogram, trans-thoracic echocardiography, and carotid artery duplex for measuring intimal thickness, peripheral arterial and venous duplex, computed tomography pulmonary angiography, and full ophthalmological examination. Regarding the activity of the disease, it was assessed according to the score of Behçet’s Disease Current Activity Form (BDCAF).

Results

The most common cardiac manifestation was valvular lesion (67.5%) where the most frequently affected valve was the tricuspid valve (27.5%). Although 25% of patients had left ventricular diastolic dysfunction, only 5% had intracardiac masses. Approximately 52.5% of patients had vascular lesion (deep venous thrombosis 45%, arterial involvement 7.5% [as pulmonary artery thrombosis 5% and aneurysm 2.5%]). Increase in intima media thickness (IMT) was observed in 7.5% of patients, while 60% had abnormal lipid profiles. Hypercholesterolemia was the most common lipid abnormality (50%). BDCAF score range was 4–12, which was significantly correlated to multiple cardiovascular parameters as a mitral, tricuspid valve, and vascular venous involvement (p < 0.05), while not significantly correlated to lipid profile (p > 0.05).

Conclusion

Cardiovascular complications are frequent among patients with BD, even those who are asymptomatic; therefore, these complications must be screened for early detection and proper management.

The association of inflammatory markers and echocardiographic parameters in Behçet's disease

Background: The main objective of the current study is to find out if any association exists between specific inflammatory markers such as homocysteine (Hcy) and pentraxin-3 (PTX-3) and cardiac involvement determined by means of echocardiographic parameters in patients with Behçet disease (BD).Methods: From January 2011 to January 2012, a total of 62 Behçet's patients were enrolled in the study. Thirty-two healthy subjects constituted the control group. The diagnosis of BD was made as proposed by International Study Group of BD.Results: The mean PTX-3, Hcy, and C-reactive protein levels were significantly higher in patients with BD compared to the control group. The electromechanical delay (EMD) times were found to be prolonged in patients with BD. Also, the aortic stiffness index (SI) and elastic modulus (Ep) were significantly higher, while the aortic dispensibility was significantly lower in patients with BD. The left atrial volume, left atrial volume index, E/A ratio, E/E' septal, IRight-EMD, PA'-ML, PA'-MS, PA'-TL, SI, and Ep were correlated with PTX-3 levels. In addition, the E/A, PA'-ML, PA'-MS, SI, and Ep displayed correlation with Hcy levels in patients having BD.Conclusion: Elevated levels of PTX-3 and Hcy were found to be correlated with cardiac involvement determined by means of echocardiographic parameters in patients with BD.

Evaluation of the relationship between Behcet's disease and cardiovascular disorders through metabolic function and copeptin

Introduction

Behcet's disease (BD) is a chronic inflammatory and multisystem vasculitis. Cardiac involvement is one of the major complications of BD. Cardiac involvement is sporadic in terms of its specific relationship to mortality. How to identify and follow up on cardiac-related complications in BD patients has yet to be determined.

Aim

The aim of our study is to assess cardiovascular diseases in BD patients by measuring metabolic function and copeptin levels and comparing these to a healthy control group. Knowing the specific metabolic functions that are negatively affected by BD will help doctors determine which functions need to be more closely monitored in BD patients. Our study is the first study in the available literature that evaluates copeptin in BD patients.

Material and methods

A control group of 58 healthy volunteers, including 32 females and 26 males (average age: 39.8 ±10.3 years, range: 18-50 years), was formed to compare with 84 BD patients (average age: 40.5 ±11 years, range: 21-63 years), including 39 females and 45 males. Diastolic and systolic blood pressure, height, weight, body mass index (BMI), and waistline were measured for both groups. All study patients were also given hemograms, and fasting blood sugar (FBS), uric acid, lipid profile, insulin, C-reactive protein (CRP), and copeptin levels were measured. An ELISA Kit was used to measure copeptin.

Results

FBS, CRP, and insulin levels were significantly higher in the patient group (p < 0.001, p = 0.004, and p = 0.038, respectively). Patients who had had the disease for more than 10 years had higher BMIs, total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels (p = 0.034, p = 0.004, p = 0.016, and p = 0.045, respectively). Additionally, CRP levels were found to be higher in long-term patients and patients with active lesions. Diastolic blood pressure and waist circumference were also higher in the BD group. Patients who had active lesions had significantly higher diastolic blood pressure (p = 0.047). There were no statistically significant differences in copeptin levels between BD and control groups.

Conclusions

Cardiovascular involvement rarely contributes to the high mortality rate of BD patients. There were meaningful elevations in metabolic markers identified when BD and cardiovascular disease risk was assessed with metabolic parameters. The cardiac disease risk should be closely followed using metabolic functions, particularly in long-term BD patients with vascular involvement.

Cardiac findings in patients with Behçet's disease: Facts and controversies

Behçet’s disease (BD) is a systemic vasculitis of unknown etiology. It is characterized by recurrent oral and genital ulcers, uveitis, and a number of systemic manifestations. Although the disease is recognized worldwide, its prevalence is highly variable. A detailed review and analysis of the worldwide published reports on BD showed that not only the prevalence of the disease but also its cardiac complications differ according to the geographic distribution of the studied population. With the exception of France, Greece, Spain, and Italy, very few reports and studies regarding BD have been published from the western countries. Cardiovascular complications are an important cause of poor outcome in patients with BD. Over the past few years, many case reports and studies have been published, providing more facts about these complications. For example, peculiar echocardiographic findings in patients with aortic valve regurgitation and intracardiac thrombi secondary to BD were recently described. The role of these findings in the initial diagnosis of the disease, however, remains to be evaluated. On the other hand, some reports present contradictory results, especially concerning the left ventricular diastolic function, pathogenesis of coronary artery disease, and proper management of the cardiac complications in BD. Importantly, management of these complications is based mainly on the discretion of the treating physician due to the absence of large controlled studies and clear guidelines. This approach sometimes creates inconsistent data and allows controversies to persist. The review presented here will discuss some of the facts and controversies related to cardiac complications in BD.

Carotid artery stiffness in Behçet's disease

OBJECTIVE

Increased carotid arterial stiffness (CAS) is a predictor of subclinical early atherosclerosis as well as carotid intima-media thickness (cIMT). We aimed to determine CAS and cIMT in Behçet's disease (BD).

MATERIAL AND METHODS

BD (n=49) and rheumatoid arthritis (RA) (n=64) patients and healthy controls (HC) (n=40) were included in the study. cIMT was measured. CAS indices, including arterial compliance (AC), arterial distensibility (AD), Young's elastic modulus (YEM), Peterson's elastic modulus (Ep), and β stiffness index (βSI) were measured based on the diameter-pressure relationship.

RESULTS

When compared to the HC group, the mean cIMT was significantly higher in the RA group (p=0.033), but it was not higher in the BD group. The CAS indices, including AD, AC, Ep, and βSI were not significantly different among the study groups. Moreover, the cIMT and CAS indices were not significantly different between active (n=20) and inactive BD patients, and these indices were not correlated with the scores of disease activity. AD, AC and Ep were significantly lower in the BD patients with a positive pathergy reaction than in those with a negative reaction.

CONCLUSION

These results suggest that BD does not directly lead to arterial stiffness or to an increase in cIMT.

Noninvasive Imaging of Flow and Vascular Function in Disease of the Aorta

With advancements in technology and a better understanding of human cardiovascular physiology, research as well as clinical care can go beyond dimensional anatomy offered by traditional imaging and investigate aortic functional properties and the impact disease has on this function. Linking the knowledge of the histopathological changes with the alterations in aortic function observed on noninvasive imaging results in a better understanding of disease pathophysiology. Translating this to clinical medicine, these noninvasive imaging assessments of aortic function are proving to be able to diagnose disease, better predict risk, and assess response to therapies. This review is designed to summarize the various hemodynamic measures that can characterize the aorta, the various noninvasive techniques, and applications for various disease states.

Cardiac Function and Diastolic Dysfunction in Behcet's Disease: A Systematic Review and Meta-Analysis

Background. Cardiovascular involvement in Behcet's disease (BD) is reported and has variable manifestations. It is not clear if diastolic dysfunction (DD) is increased in BD. Our objective was to evaluate the existing literature to determine if cardiac dysfunction, particularly DD, was more prevalent in these patients. Methods. A systematic review and meta-analysis of the available studies analyzing the echocardiographic findings in BD was conducted using a random-effects model. Mean differences were used to calculate the effect sizes of the echocardiographic parameters of interest. Results. A total of 22 studies with 1624 subjects were included in the analysis. Patients with BD had statistically significantly larger mean left atrial dimension (0.08, p = 0.0008), greater aortic diameter (0.16, p = 0.02), significantly reduced ejection fraction (−1.08, p < 0.0001), significantly prolonged mitral deceleration time (14.20, p < 0.0001), lower E/A ratio (−0.24, p = 0.05), and increased isovolumetric relaxation time (7.29, p < 0.00001). Conclusion. DD is increased in patients with BD by the presence of several echocardiographic parameters favoring DD as compared to controls. The meta-analysis also identified that LA dimension is increased in BD patients. EF has also been found to be lower in BD patients. Aortic diameter was also increased in BD patients as compared to controls.

Assessment of Left Ventricular Diastolic Function in Egyptian Patients With Behçet's Disease

Objectives

This study aims to evaluate left ventricular diastolic function in Egyptian patients with Behçet's disease using variable echocardiographic parameters by combining both transmitral and tissue Doppler velocities to overcome the occasional false interpretation of preload dependent transmitral parameters and to detect the correlation between various left ventricular diastolic parameters and different disease manifestations.

Patients and methods

Forty patients (35 males, 5 females; mean age 31±8 years; range 19 to 52 years) with Behçet's disease and 32 age- and sex- matched healthy controls (26 males, 6 females; mean age 28±6 years; range 19 to 60 years) were enrolled. Left ventricular diastolic function was assessed using an algorithm that combined transmitral and tissue Doppler derived parameters.

Results

Mean disease duration of the patients was 7.4±6 years. Left and right ventricular systolic function was normal in both groups. The transmitral E/A was<1 in six patients (15%). There was no difference between patients and controls regarding the other left ventricular diastolic parameters. Compared to patients with an E/A ratio >1, patients with E/A<1 were significantly older and had a longer disease duration (p=0.001 and p<0.001, respectively). All the other echocardiographic parameters in both groups were comparable.

Conclusion

Egyptian patients with Behçet's disease have normal left ventricular diastolic function regardless of disease duration and activity.

Non-dipping blood pressure patterns and arterial stiffness parameters in patients with Behcet's disease

Behcet's disease is a multisystemic vasculitis involving veins and arteries of various sizes. Non-dipping status, augmentation index and pulse wave velocity are important determinants of cardiovascular mortality and morbidity. We investigated the non-dipping status and arterial stiffness in patients with Behcet's disease. In this cross-sectional study, we examined the vascular parameters of 96 patients with Behcet's disease (53% female) and 60 age- and sex-matched control subjects. The non-dipping status and arterial distensibility were assessed using a Mobil-O-Graph Arteriograph, an automatic oscillometric device. In total, 65.6% of 96 patients were systolic non-dippers, and 34.4% exhibited high augmentation indices. Ten percent of the control subjects were systolic non-dippers, and 11.7% exhibited high augmentation indices. Nocturnal decreases in systolic blood pressure correlated with central systolic blood pressure and diastolic blood pressure, as well as nocturnal decreases in diastolic blood pressure. Furthermore, non-dipper patients with Behcet's disease exhibited higher nocturnal cardiac outputs than did dipper patients with Behcet's disease. Augmentation index correlated negatively with C-reactive protein and correlated positively with both 24 h and nocturnal peripheral resistance, as well as 24 h pulse wave velocity. The patients with high augmentation indices exhibited lower creatinine clearance, as well as lower nocturnal cardiac outputs, higher 24 h peripheral resistance and higher 24 h pulse wave velocities. Non-dipping status and arterial stiffness may exacerbate the harmful cardiovascular effects of the other. In addition to conventional risk factors, non-dipping status and arterial stiffness should be examined during the follow-up evaluations of patients with Behcet's disease.

The assessment of cardiac functions by tissue Doppler-derived myocardial performance index in patients with Behcet’s disease

Vascular involvement is one of the major characteristics of Behcet's disease (BD). However, there are controversial findings regarding cardiac involvement in BD. Although early reports demonstrated that there is diastolic dysfunction in BD, conflicting results were found in the following trials. Hence, a new method for more objectively estimating the cardiac functions is needed. For this aim, we used high-usefulness tissue Doppler echocardiography for detailed analysis of cardiac changes in BD patients because this method was superior to other conventional echocardiographic techniques. The study population included 42 patients with BD (19 men, 23 women; mean age, 35 +/- 10 years, mean disease duration, 2.7 +/- 1.6 years) and 30 healthy subjects (14 men, 16 women; mean age, 38 +/- 7 years). Cardiac functions were determined using echocardiography, comprising standard two-dimensional and conventional Doppler and tissue Doppler imaging (TDI). Peak systolic myocardial velocity at mitral annulus, early diastolic mitral annular velocity (Em), late diastolic mitral annular velocity (Am), Em/Am, and myocardial performance index (MPI) were calculated by TDI. The conventional echocardiographic parameters and tissue Doppler measurements were similar between the groups. Tissue Doppler derived mitral relaxation time was longer (75 +/- 13 vs 63 +/- 16 msn, p = 0.021) in patients with BD. There was statistically significant difference between the two groups regarding left ventricular MPI (0.458 +/- 0.072 vs 0.416 +/- 0.068%, p = 0.016), which were calculated from tissue Doppler systolic time intervals. There was also significant correlation between the disease duration and MPI (r = 0.38, p = 0.017). We have demonstrated that tissue Doppler-derived myocardial left ventricular relaxation time and MPI were impaired in BD patients, although systolic and diastolic function parameters were comparable in the patients and controls.

Changes in cerebral and ocular hemodynamics in Behçet's disease assessed by color-coded duplex sonography

AIM

To quantify the cerebral and retrobulbar hemodynamics in Behçet's disease with and without ocular involvement and compared with that of healthy controls.

MATERIALS AND METHODS

Of 51 people studied, 17 had Behçet's disease with ocular involvement, 17 had Behçet's disease without ocular involvement, and 17 were healthy controls. A single eye was examined in each patient. Peak systolic velocity (PSV), end-diastolic velocity (EDV), time-averaged maximum velocity (Tamax), and resistance index (RI) were evaluated in the ophthalmic (OA), posterior ciliary (PCA), central retinal (CRA) and middle cerebral artery (MCA). Additionally, the average blood flow velocities in the central retinal vein (CRV), and acceleration time (AT) and pulsatility index (PI) in the MCA were calculated.

RESULTS

The mean EDV in the PCA was 25% lower and RI was higher in patients with ocular involvement of BD than in patients without involvement (p = 0.006 and p = 0.005, respectively) and in healthy controls (p = 0.003 and p = 0.004, respectively). Differences were smaller in comparisons of the CRA and absent on comparisons of the OA and MCA. The acceleration time of the MCA was significantly higher in patients with Behçet's disease than in healthy controls (p = 0.03).

CONCLUSION

This study suggests that the flow hemodynamics in retrobulbar circulation has more altered Behçet's disease with ocular involvement than without ocular involvement and healthy control. Additionally, the cerebral hemodynamic might be affected in patients with Behçet's disease compared with healthy controls.
