Lower Extremity Arterial Disease in Patients with Type 2 Diabetes: Prevalence and Associated Factors at the Libreville University Hospital Center

Introduction: Lower extremity arterial disease in diabetic patients has distinct characteristics. Objectives: To study the hospital frequency of lower extremity arterial disease and identify associated factors in diabetic patients at the Libreville University Hospital Center (CHUL). Materials and Methods: This was a cross-sectional study conducted from July 1, 2023, to January 31, 2024, in the endocrinology department of the CHUL. All patients with type 2 diabetes over the age of 18 admitted to this department, regardless of the reason for hospitalization, who provided informed consent, were included. Socio-demographic data and cardiovascular risk factors were recorded. Personal and family cardiovascular history and functional symptoms were investigated. The physical examination included measuring blood pressure, heart rate, and the ankle-brachial index in all patients. Results: A total of 219 patients were included, of whom 75 had lower extremity arterial disease, representing a prevalence of 34.24%. It was compensated in 28 cases (37.33%) and decompensated in 39 patients (52%). In eight cases (10.67%), there was critical chronic ischemia. Cardiovascular risk factors associated with diabetes were physical inactivity (89.5%), hypertension (55.25%), overweight (49.77%), obesity (22.84%), and smoking (10.04%). In multivariate analysis, only hypertension (OR = 2.09;95% CI: 1.05 - 4.17;p = 0.035) and LDL cholesterol (OR = 2.75;95% CI: 1.10 - 6.85;p = 0.03) were significantly associated with lower extremity arterial disease in diabetics at the University Hospital of Libreville. Conclusion: Lower extremity arterial disease is common in diabetic patients at the University Hospital of Libreville. It is often asymptomatic, thus requiring systematic screening.[-rId11-]

Risk Stratification and Prognosis of Pulmonary Arterial Hypertension Associated with Congenital Heart Disease

Background:Current guidelines for managing pulmonary arterial hypertension(PAH)recommend a risk strati-fication approach.However,the applicability and accuracy of these strategies for PAH associated with congenital heart disease(PAH-CHD)require further validation.This study aims to validate the reliability and predictive accuracy of a simplified stratification strategy for PAH-CHD patients over a three-year follow-up.Additionally,new prognostic variables are identified and novel risk stratification methods are developed for assessing and managing PAH-CHD patients.Methods:This retrospective study included 126 PAH-CHD patients.Clinical and biochemical variables across risk groups were assessed using Kruskal-Wallis and Fisher’s exact tests.Indepen-dent risk factors were identified using ordered logistic regression,while Kaplan-Meier and Cox proportional hazards regression analyses evaluated their impact on all-cause mortality.A new stratification model for the PAH-CHD population was constructed based on these analyses.Results:Significant survival differences across stratified risk groups were observed(p<0.001),validating the effectiveness of the simplified risk stratification method in PAH-CHD patients.Prothrombin activity was a strong independent predictor of adverse outcomes of PAH-CHD patients(Hazard ratio 0.95,p<0.001,C-index 0.70).A model combining N-terminal pro-brain natriuretic peptide,prothrombin activity,albumin,and right atrial area achieved an area under the curve of 0.89 and a C-index of 0.85.Conclusions:The simplified risk stratification method is applicable to PAH-CHD patients.Prothrombin activity is a strong independent predictor of adverse outcomes.A comprehensive risk stratification approach,incorporating both established and novel biomarkers,enhances accessibility and offers predictive efficacy during follow-up for PAH-CHD patients,comparable to established models.

Pilot study on the effect of flavonoids on arterial stiffness and oxidative stress in chronic kidney disease

BACKGROUND Flavonoids,the main class of polyphenols,exhibit antioxidant and antihypertensive properties.AIM To prospectively investigate the impact of flavonoids on arterial stiffness in patients with chronic kidney disease(CKD)stagesⅠ-Ⅳ.METHODS In this prospective,single-arm study,CKD patients with arterial hypertension and diabetes mellitus were enrolled.Baseline demographic,clinical,and laboratory variables were recorded.Patients received daily treatment with a phenol-rich dietary supplement for 3 months.Blood pressure,arterial stiffness(carotidfemoral pulse wave velocity,central pulse pressure),and oxidative stress markers(protein carbonyls,total phenolic compound,total antioxidant capacity)were measured at baseline and at study end.RESULTS Sixteen patients(mean age:62.5 years,87.5%male)completed the study.Following intervention,peripheral systolic blood pressure decreased significantly by 14 mmHg(P<0.001).Carotid-femoral pulse wave velocity decreased from 8.9 m/s(baseline)to 8.2 m/s(study end)(P<0.001),and central pulse pressure improved from 59 mmHg to 48 mmHg(P=0.003).Flavonoids also reduced oxidative stress markers including protein carbonyls(P<0.001),total phenolic compound(P=0.001),and total antioxidant capacity(P=0.013).CONCLUSION Flavonoid supplementation in CKD patients shows promise in improving blood pressure,arterial stiffness,and oxidative stress markers.

Imperative for long-term management and surveillance in Kawasaki disease

Kawasaki disease(KD)is a significant pediatric vasculitis known for its potential to cause severe coronary artery complications.Despite the effectiveness of initial treatments,such as intravenous immunoglobulin,KD patients can experience long-term cardiovascular issues,as evidenced by a recent case report of an adult who suffered a ST-segment elevation myocardial infarction due to previous KD in the World Journal of Clinical Cases.This editorial emphasizes the critical need for long-term management and regular surveillance to prevent such complications.By drawing on recent research and case studies,we advocate for a structured approach to follow-up care that includes routine cardiac evaluations and preventive measures.

Current status of high on-treatment platelet reactivity in patients with coronary or peripheral arterial disease:Mechanisms,evaluation and clinical implications

Antiplatelet therapy with aspirin or clopidogrel or both is the standard care for patients with proven coronary or peripheral arterial disease,especially those undergoing endovascular revascularization procedures. However,despite the administration of the antiplatelet regiments,some patients still experience recurrent cardiovascular ischemic events. So far,it is well documented by several studies that in vitro response of platelets may be extremely variable. Poor antiplatelet effect of clopidogrel or high on-treatment platelet reactivity(HTPR) is under investigation by numerous recent studies. This review article focuses on methods used for the ex vivo evaluation of HTPR,as well as on the possible underlying mechanisms and the clinical consequences of this entity. Alternative therapeutic options and future directions are also addressed.

PREVALENCE AND RISK FACTORS OF PERIPHERAL ARTERIAL DISEASE IN DIABETIC PATIENTS OVER 50 YEARS OLD IN CHINA

Objective To investigate the prevalence of peripheral arterial disease (PAD) in China type 2 diabetic patients and to demonstrate the relationships between putative risk factors and PAD. Methods In total 1 397 type 2 diabetic patients aged 50 years and older were enrolled and determined ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) in 15 Class III Grade A hospitals in 7 major cities of China. Results Mean patient age was 63.7±8.2 years and mean duration of diabetes mellitus was 9.39±7.4 years. Two hundreds and seventy-two (19.47%) patients were diagnosed as PAD by ABI <0.9, 122 (18.37%) in male and 150 (20.46%) in female. PAD patients had a significantly longer duration of diabetes mellitus, higher hemoglobin Alc, and a significantly lower mean body mass index than non-PAD ones. Aging, smoking, and systolic blood pressure were found to be positively related with the prevalence of PAD. In terms of lipid profiles, no variable was found to relate with PAD. Notably, baPWV showed as the same significant guiding index for PAD, almost matched with ABI. Conclusions PAD is a common complication in China type 2 diabetic patients. Therefore, PAD screening and treatment should be emphasized for diabetic patients with high risk factors.

INTRACRANIAL ARTERIAL OCCLUSIVE LESION IN PATIENTS WITH GRAVES DISEASE

Objective To investigate the distribution and clinical manifestations of intracranial arterial occlusive lesions （IA- OLs）, and their correlation with thyroid function. Methods We enrolled 7 patients who had Graves＇ disease （GD） with IAOLs screened and evidenced by transcranial Doppler, then further confirmed with digital substract angiography in 2 patients and magnetic resonance angiography in 5 patients. Brain magnetic resonance imaging （MRI） was performed in all 7 patients. Three patients were followed up. Results Among 7 patients, 1 was male and 6 were females. The mean age was 32.0 ± 5.5 （ range from 11 to 49） years old. Six of them had symptoms of GD but one was asymptomatic with abnormality of I3, T4, and thyroid stimulating hormone. The lesions of intracranial arteries were symmetrical bilaterally in the intemal carotid artery system in 6 patients, as well as asymmetrical in 1 patient. Terminal internal carotid artery （TICA） were involved in all 7 patients. Middle cerebral artery （MCA） were involved in 3, anterior cerebral artery in 2, and basilar artery in 1 patient. Net-like collateral vessels and mimic moyamoya disease were observed in the vicinity of the occlusive arteries in 2 patients. All patients presented symptoms of ischemic stroke including transient ischemic attack and/or infarction while IA- OLs were found. Three patients had obvious involuntary movements. Brain MRI revealed infarctions located in the cortex, basal ganglion, or hemiovular center in 5 patients. The remaining 2 patients had normal brain MRI. The neurological symptoms were improved concomitant with relief of the thyroid function in 2 patients, while IAOLs were aggravated with deterioration of the thyroid function in 1 patient. Conclusion IAOLs in patients with GD mainly involve intracranial arteries, especially the TICA and MCA, which is similar to moyamoya disease. The neurological symptoms and severity of involved arteries may relieve while the hyperthyroidism is gradually under control.

Association of arterial stiffness with coronary flow reserve in revascularized coronary artery disease patients

AIM: To investigate the association of arterial wave reflection with coronary flow reserve(CFR) in coronary artery disease(CAD) patients after successful revascularization.METHODS: We assessed 70 patients with angiographically documented CAD who had undergone recent successful revascularization. We measured(1) reactive hyperemia index(RHI) using fingertip peripheral arterial tonometry(RH-PAT Endo-PAT);(2) carotid to femoral pulse wave velocity(PWVc-Complior);(3) augmentation index(AIx), the diastolic area(DAI%) and diastolic reflection area(DRA) of the central aortic pulse wave(Arteriograph);(4) CFR using Doppler echocardiography; and(5) blood levels of lipoprotein-phospholipase A2(LpPLA2).RESULTS: After adjustment for age, sex, blood pressure parameter, lipidemic, diabetic and smoking status, we found that coronary flow reserve was independently related to AIx(b =-0.38, r = 0.009), DAI(b = 0.36, P = 0.014), DRA(b = 0.39, P = 0.005) and RT(b =-0.29,P = 0.026). Additionally, patients with CFR < 2.5 had higher PWVc(11.6 ± 2.3 vs 10.2 ± 1.4 m/s, P = 0.019), SBPc(139.1 ± 17.8 vs 125.2 ± 19.1 mm Hg, P = 0.026), AIx(38.2% ± 14.8% vs 29.4% ± 15.1%, P = 0.011) and lower RHI(1.26 ± 0.28 vs 1.50 ± 0.46, P = 0.012), DAI(44.3% ± 7.9% vs 53.9% ± 6.7%, P = 0.008), DRA(42.2 ± 9.6 vs 51.6 ± 11.4, P = 0.012) and Lp PLA2(268.1 ± 91.9 vs 199.5 ± 78.4 ng/m L, P = 0.002) compared with those with CFR ≥ 2.5. Elevated Lp PLA2 was related with reduced CFR(r =-0.33, P = 0.001), RHI(r =-0.37, P < 0.001) and DRA(r =-0.35, P = 0.001) as well as increased PWVc(r = 0.34, P = 0.012) and AIx(r = 0.34, P = 0.001). CONCLUSION: Abnormal arterial wave reflections are related with impaired coronary flow reserve despite successful revascularization in CAD patients. There is a common inflammatory link between impaired aortic wall properties, endothelial dysfunction and coronary flow impairment in CAD.

Transgelin as a potential target in the reversibility of pulmonary arterial hypertension second to congenital heart disease

Background The reversibility of pulmonary arterial hypertension(PAH)in congenital heart disease(CHD)is of great importance for the operability of CHD.Proteomics analysis found that transgelin was significantly upregulated in the lung tissue of CHD-PAH patients,especially in the irreversible group.However,how exactly it participated in CHD-PAH development is unknown.

Prevalence of Anti-endothelial Cell Antibodies in Patients with Pulmonary Arterial Hypertension Associated with Connective Tissue Diseases

Objective To investigate the prevalence of anti-endothelial cell antibodies (AECAs) in the sera of connective tissue diseases (CTD) patients with pulmonary arterial hypertension (PAH) and its correlation with clinical manifestations. Methods AECAs in sera of 39 CTD patients with PAH,22 CTD patients without PAH,and 10 healthy donors as controls were detected with Western blotting. The prevalence of different AECAs in different groups was compared and its correlation with clinical manifestations was also investigated. Results The prevalence of AECAs was 82.1% in CTD patients with PAH,72.7% in CTD patients without PAH,and 20.0% in healthy donors. Anti-22 kD AECA was only detected in CTD patients with PAH (15.4%). Anti-75 kD AECA was more frequently detected in CTD patients with PAH than in those without PAH (51.3% vs. 22.7%,P<0.05). In CTD patients with PAH,anti-75 kD AECA was more frequently detected in those with Raynaud’s phenomenon or with positive anti-RNP antibody. Conclusion AECAs could be frequently detected in CTD patients with or without PAH,while anti-22 kD and anti-75 kD AECA might be specific in CTD patients with PAH.

Peripheral arterial disease, type 2 diabetes and postprandial lipidaemia: Is there a link?

Peripheral arterial disease, manifested as intermittent claudication or critical ischaemia, or identified by an ankle/brachial index < 0.9, is present in at least one in every four patients with type 2 diabetes mellitus.Several reasons exist for peripheral arterial disease indiabetes. In addition to hyperglycaemia, smoking and hypertension, the dyslipidaemia that accompanies type2 diabetes and is characterised by increased triglyceride levels and reduced high-density lipoprotein cholesterol concentrations also seems to contribute to this association. Recent years have witnessed an increased interest in postprandial lipidaemia, as a result of various prospective studies showing that non-fasting triglycerides predict the onset of arteriosclerotic cardiovascular disease better than fasting measurements do. Additionally,the use of certain specific postprandial particle markers,such as apolipoprotein B-48, makes it easier and more simple to approach the postprandial phenomenon. Despite this, only a few studies have evaluated the role of postprandial triglycerides in the development of peripheral arterial disease and type 2 diabetes. The purpose of this review is to examine the epidemiology and risk factors of peripheral arterial disease in type 2 diabetes, focusing on the role of postprandial triglycerides and particles.

Risk of coronary arterial lesions in immunoglobulin resistant Kawasaki disease

Objective: High-dose intravenous immunoglobulin (IVIG) decreases the risk for development of coronary arterial lesions (CAL) in Kawasaki disease (KD) while patients resistant to IVIG have higher risk. This study is aimed to investigate an additional therapy affects the risk for CAL in IVIG resistant KD. Design: The information from 11,510 children with KD was collected by the nationwide survey (2003-2004) in Japan. The secondary therapeutic strategies for IVIG resistant KD were an additional IVIG dose, steroids or both. The incidence of CAL was compared among 4 groups: G1, children responded to initial IVIG;G2, IVIG resistant patients receiving an additional IVIG dose;G3, IVIG resistant patients receiving additional steroids;G4, IVIG resistant patients receiving an additional IVIG dose plus steroids. CAL was assessed at 30th day of illness using ultrasound echocardiography. Results: 2229 patients (19.4%) were resistant to initial IVIG. Incidence of CAL was significantly lower in children responding to initial IVIG than in IVIG resistant patients (1.9% and 11.0%, respectively;odd’s ratio 6.3). The incidences of CAL in an each additional therapy group were as follows: G2: 6.7%, G3: 9.7%, G4: 22.2%. The risk for CAL was significantly higher in G4 as compared with G2 and G3. Giant aneurysmal formation (GA) was more frequently developed in G3 and G4 consisting of the patients receiving steroids (G1: 0.03%, G2: 0.63%, G3: 4.3%, G4: 3.7%). Conclusion: The incidence of CAL was considerably high in IVIG resistant KD and an additional therapy by steroids may increase the risk for GA.

Association between Free Triiodothyronine Levels and Peripheral Arterial Disease in Euthyroid Participants

This current cross-sectional study investigates the relationship between thyroid hormones and peripheral artery disease （PAD） among euthyroid Chinese population aged 40 years and above. Serum free triiodothyronine （FT3）, free thyroxin （FT4）, thyroid-stimulating hormone （TSH）, and thyroid antibodies were measured.

Arterial hypertension and electrocardiographic diagnosis of left ventricular hypertension in the group of geriatric patients with coronary heart disease living in the far north

As a result of research, high prevalence of arterial hypertension has been identified in the group of patients with coronary heart disease aged 60 and older. Most often, occurring form of arterial hypertension among geriatric patients is isolated systolic arterial hypertension (ISAH). The comparison of two ethnic groups of the population has showed higher levels of systolic and diastolic blood pressure (SBP and DBP) in the group of patients of non-indigenous nationality, rather than Yakut patients. Correlation was recorded in the group of non-indigenous patients as they age. Significant increase in the level of SBP was identified in the group of senile and long-livers than in the elderly. Detection of ECG signs of LVH showed the lowest specificity of Cornell voltage criterion comparing to Sokolow-Lyon criterion with its more often occurrence. ECG-signs of left ventricle hypertrophy are significantly more often established by Sokolow-Lyon criterion for men, Cornell voltage—for women. Correlation has been found between the presence of LVH and combination of Cornell voltage criterion with both Gubner-Ungerleider and Sokolow-Lyon criteria.

Current evidence of drug-elution therapy for infrapopliteal arterial disease

New and sophisticated endovascular devices, such as drug-eluting stents(DES)and drug-coated balloons(DCB), provide targeted drug delivery to affected vessels. The invention of these devices has made it possible to address the reparative cascade of arterial wall injury following balloon angioplasty that results in restenosis. DESs were first used for the treatment of infrapopliteal lesions almost 20 years ago. More recently, however, DCB technology is being investigated to improve outcomes of endovascular below-the-knee arterial procedures, avoiding the need for a metallic scaffold. Today, level IA evidence supports the use of infrapopliteal DES for short to medium length lesions,although robust evidence that justifies the use of DCBs in this anatomical area is missing. This review summarizes and discusses all available data on infrapopliteal drug-elution devices and highlights the most promising future perspectives.

The Role of Color Doppler Ultrasound Arterial Mapping for Decision Making in the Treatment of Patients with Lower Extremity Peripheral Arterial Disease

Purpose: To assess the efficacy of color Doppler imaging for decision making in the treatment of patients with lower extremity peripheral arterial disease (PAD) compared to digital subtraction angiography (DSA). Materials and Methods: Color Doppler scan was done on patients suspected for lower limb PAD, a day prior to the DSA which was done by a vascular surgeon. Also, for the patients who were candidates for endovascular intervention based on the color Doppler arterial mapping results, endovascular interventions were performed at the same time if the DSA findings are correlated with the color Doppler map. The grading for evaluated segments was normal, insignificant stenosis (<50%), hemodynamically significant stenosis (≥50%) and occlusion. We yielded the diagnostic efficacy indices of Doppler for detecting arterial stenosis in each 18 different arterial segments below the renal arteries including, infrarenal aorta, common and external iliac, common femoral, superficial femoral (proximal, middle and distal segments), deep femoral, popliteal artery, tibioperoneal trunk, anterior and posterior tibial arteries (proximal, middle and distal segments) and peroneal artery (proximal and distal segments). Then, we yielded the kappa agreement between Doppler and DSA findings considering the grade of stenosis in 18 arterial segments separately. Results: Totally 115 lower extremities (2045 arterial segments) were evaluated in 90 patients [mean age: 60.8 ± 8.9 (range: 47 - 84 years old)] of which 68 (75.6%) were men. The sensitivity of color Doppler for all arterial segments was 90% or higher except for common iliac artery, distal segment of superficial femoral artery and proximal segments of anterior and posterior tibialis and peroneal arteries. However, the specificity was 89% or higher, in all arterial segments. Kappa agreement was 0.72 or higher in all segments (All P-Values 0.001). Conclusion: This study suggests that considering excellent capability of color Doppler sonography in the evaluation of lower extremity arterial disease, color Doppler arterial mapping is sufficient for decision making in the treatment of these patients and can reduce the rate of diagnostic angiography.

Pulmonary Arterial Hypertension Medical Management of the Adult Patient with Congenital Heart Disease

Congenital heart disease(CHD)-associated pulmonary arterial hypertension(PAH)includes a heterogeneous patient population that can be characterized by the underlying cardiac malformation.CHD-associated PAH has an estimated prevalence of 5– 10% in adult patients,with an increasing number of patients surviving to adulthood because of advances in the surgical management and the development of pulmonary arterial hypertension(PAH)-targeted pharmacotherapy.Although limited data exist,targeted PAH pharmacotherapy has proven to be benefi cial in patients with CHD-associated PAH,with observed improvement in functional class,increase in exercise capacity,and improvement in quality of life and cardiopulmonary hemodynamics.Additionally,there has been increasing interest in the“treat-to-close”strategy.PAH-targeted pharmacotherapy may be used to optimize cardiopulmonary hemodynamics so as to improve patients’operability in repairing the cardiac defect.Although there have been signifi cant advances in the management of this disease state in the past 2 decades,mortality remains high,and ongoing clinical trials are needed to better understand the treat-to-close strategy.

Selexipag as Add-on Therapy for Patients with Pulmonary Arterial Hypertension Associated with Congenital Heart Disease:A Single-Center Retrospective Study

Purpose:This study examined the efficacy and safety of selexipag in treating pulmonary arterial hypertension(PAH)associated with congenital heart disease(CHD).Materials and Methods:We conducted a retrospective study of patients with CHD-associated PAH,treated with selexipag since December 2017.Thirteen adult patients(mean age,45.4 years;women,77%)were treated with selexipag as add-on therapy.Baseline characteristics,World Health Organization functional class,6-minute walking distance(6MWD)test results,N-terminal pro-B-type natriuretic peptide levels,echocardiographic data,and incidence of side effects were assessed.Results:The majority of patients(12/13,92.3%)experienced more than one treatment-associated complication;one patient dropped out of the study due to intolerable myalgia.The results of 6MWD test(from 299.2±56.2 m to 363.8±86.5 m,p=0.039)and tricuspid regurgitation(TR)pressure gradient(from 84.7±20.5 mmHg to 61.6±24.0 mmHg,p=0.018)improved and remained improved after selexipag treatment in 12 patients.Based on the results of a non-invasive risk assessment,8(66.7%)patients showed improvement,3(25.0%)showed no interval change,and the status of one patient(8.3%)deteriorated.Moreover,compared to patients treated with a low dosage,patients treated with a medium-to-high dosage showed a greater increase in 6MWD results(88.3±26.4 m vs.55.3±27.6 m,p=0.043)and a greater reduction in the TR pressure gradient(-33.7±10.9 mmHg vs.-12.5±12.0 mmHg,p=0.015).Conclusion:Selexipag is an efficient pulmonary vasodilator as add-on therapy in treating CHD-associated PAH.

Investigation and analysis of lower extremity arterial disease in hospitalized elderly type 2 diabetic patients

Background:The risk of lower extremity arterial disease (LEAD) is increased in diabetic patients.LEAD in diabetic patients occurs earlier and is often more severe and diffuse;however,it is largely underdiagnosed and untreated.The purposes of this study were to investigate and analyze LEAD situation of hospitalized elderly type 2 diabetic patients.Methods:The ankle-brachial index (ABI) was used to screen LEAD in hospitalized elderly type 2 diabetic patients.The patients were divided into 5 groups based on the screening results:non-LEAD group and LEAD group;the LEAD group was divided into mild stenosis group,moderate stenosis group,and severe stenosis group.Results:The percentage of patients who had LEAD was 43%.Significant difference in age,diabetes duration,peak velocity,microalbuminuria,and vibratory sensory neuropathy was observed between patients with and without LEAD;regression analysis showed that urinary albumin and vibratory sensory neuropathy were independent risk factors for LEAD.Significant difference in age,body mass index (BMI),peak velocity,urinary albumin,and high-density lipoprotein cholesterol (HDL-C) was observed between mild stenosis group,moderate stenosis group,and severe stenosis group;regression analysis showed that urinary albumin,BMI,and HDL-C were independent risk factors for accelerating vascular stenosis.Conclusions:The incidence of LEAD in hospitalized elderly type 2 diabetic patients is high;age,diabetes duration,peak velocity,BMI,urinary microalbumin,vibratory sensory neuropathy,and HDL-C are the maior risk factors for LEAD.Active control of risk factors is helpful to reduce or delay LEAD.
