Inflammation Burden and Atrial Fibrillation Burden: A Bidirectional Relationship. / Carga Inflamatória e Carga de Fibrilação Atrial: Uma Relação Bidirecional.

BACKGROUND: Atrial fibrillation (AF) burden is defined as the proportion of time the patient remains in AF over a given period of time; thus, it is theoretically highest in permanent AF and lowest in paroxysmal AF. Inflammation is associated with the initiation and maintenance of AF. However, the relationship between systemic immune-inflammation index (SII) and AF burden is unknown. OBJECTIVE: In the present study, we investigated the relationship between SII and AF burden. METHODS: The present study is a cross-sectional analysis of 453 patients (252 females and 201 males, aged 44 to 94 years) with AF (138 with paroxysmal AF and 315 with permanent AF) who visited the cardiology outpatient clinic between October 2022 and June 2023. SII was calculated as (neutrophils × platelets/lymphocytes). The predictive role of SII and other inflammatory markers in the likelihood of AF pattern was evaluated by logistic regression analyses, and p value < 0.05 was considered statistically significant. RESULTS: Age, diastolic blood pressure, heart rate, diabetes mellitus, neutrophil, platelet-to-lymphocyte ratio, neutrophil-to-lymphocyte ratio, SII, C-reactive protein, red blood cell distribution width, hemoglobin A1c, and left atrial diameter were significantly higher in the permanent AF group. According to the logistic regression analysis, age (p = 0.038), diabetes mellitus (p = 0.024), red blood cell distribution width (p = 0.023), C-reactive protein (p = 0.010), SII (p = 0.001), and left atrial diameter (p < 0.001) significantly contributed to the prediction of the likelihood of permanent AF. CONCLUSION: SII is independently associated with the AF burden. Prospective studies are needed to determine whether SII may be useful in identifying patients at high risk for AF progression.

FUNDAMENTO: A carga de fibrilação atrial (FA) é definida como a proporção de tempo que o paciente permanece em FA durante um determinado período de tempo; portanto, é teoricamente mais elevado na FA permanente e mais baixo na FA paroxística. A inflamação está associada ao início e à manutenção da FA. No entanto, a relação entre o índice de inflamação imune sistêmica (SII, do inglês systemic immune-inflammation index) e a carga de FA é desconhecida. OBJETIVO: No presente estudo, investigamos a relação entre o SII e a carga de FA. MÉTODOS: O presente estudo é uma análise transversal de 453 pacientes (252 do sexo feminino e 201 do sexo masculino, com idade entre 44 e 94 anos) com FA (138 com FA paroxística e 315 com FA permanente) atendidos no ambulatório de cardiologia entre outubro de 2022 e junho de 2023. O SII foi calculado como (neutrófilos × plaquetas/linfócitos). O papel preditivo do SII e de outros marcadores inflamatórios na probabilidade do padrão de FA foi avaliado por análises de regressão logística, sendo considerado estatisticamente significativo o valor de p < 0,05. RESULTADOS: Idade, pressão arterial diastólica, frequência cardíaca, diabetes mellitus, neutrófilos, relação plaquetas-linfócitos, relação neutrófilos-linfócitos, SII, proteína C reativa, largura de distribuição de glóbulos vermelhos, hemoglobina A1c e diâmetro do átrio esquerdo foram significativamente maiores no grupo com FA permanente. De acordo com a análise de regressão logística, idade (p = 0,038), diabetes mellitus (p = 0,024), largura de distribuição de glóbulos vermelhos (p = 0,023), proteína C reativa (p = 0,010), SII (p = 0,001) e o diâmetro do átrio esquerdo (p < 0,001) contribuíram significativamente para a predição da probabilidade de FA permanente. CONCLUSÃO: O SII está independentemente associado à carga de FA. Estudos prospectivos são necessários para determinar se o SII pode ser útil na identificação de pacientes com alto risco de progressão da FA.

The Relationship Between Endocan and Serum Inflammatory Markers in Patients with Senile Calcific Aortic Stenosis.

BACKGROUND: Endocan is an indicator of many pathologies accompanied by inflammation, endothelial cell activation, and dysfunction. In this study, we examined the relationship between degenerative aortic sclerosis, which progresses in a similar pathophysiologic mechanism as atherosclerosis, and serum inflammatory markers and endocan levels. METHODS: A total of 155 patients without known coronary artery disease, aged between 65 and 80 years, were consecutively included in the prospective cross-sectional study. The study population was analyzed in 4 different groups. The control group consisted of patients with normal aortic valve structure, while patients with aortic stenosis were classified as mild aortic stenosis (2-2.9 m/s), moderate aortic stenosis (3-3.9 m/s), and severe aortic stenosis (≥ 4 m/s) according to their aortic velocity. While there were 39 patients in the control group, there were 58, 24, and 34 patients in the mild, moderate, and severe aortic stenosis groups, respectively. RESULTS: There was no statistically significant difference between the groups in terms of patient distribution and characteristics. History of dyspnea and angina was correlated with the severity of aortic stenosis (P <.001). In this study, no statistically significant correlation was found between serum endocan levels and the severity of aortic stenosis (control group: 17.3 ± 6.3 ng/mL, mild aortic stenosis: 17.6 ± 8.7 ng/mL, moderate aortic stenosis: 16.3 ± 3.8 ng/mL, severe aortic stenosis: 15.2 ± 5.9 ng/mL, P =.396). However, it was figured out that there was a positive correlation between endocan levels and hemoglobin (Hg) (r = 0.308, P =.001), platelet (PLT) (r = 0.320, P <.001), and albumin (Alb) (r = 0.206, P =.026). CONCLUSION: In this study, no significant correlation was found between serum endocan levels and the severity of aortic stenosis. On the other hand, there was a positive correlation between endocan levels and Hg, PLT, and Alb.

Conclusion SII is independently associated with the AF burden. Prospective studies are needed to determine whether SII may be useful in identifying patients at high risk for AF progression.

[Serum Carcinoembryonic Antigen Level Is Associated with Aortic Stiffness]. / Serum Karsinoembriyonik Antijen Seviyesi Aortik Sertlik ile Iliskilidir.

OBJECTIVE: Carcinoembryonic antigen is a serological marker used in the diagnosis of malignancies and is also associated with inflammatory events. It has also been reported that carcinoembryonic antigen is associated with cardiovascular diseases. However, not much is known about the relationship between arterial stiffness and carcinoembryonic antigen. In this study, we investigated the relationship between serum carcinoembryonic antigen levels and arterial stiffness. METHODS: The data of 371 (female = 192, male = 179) individuals who applied for cardiac check-up without obvious cardiovascular diseases were analyzed cross-sectionally. Echocardiography was used to assess the participants' aortic stiffness index. RESULTS: In our sample, aortic stiffness index and carcinoembryonic antigen were determined as median = 8.98, interquartile range 7.60 and median = 1.58 ng/mL, interquartile range 1.52, respectively. Aortic stiffness index and carcinoembryonic antigen levels were significantly higher in males than females. A significant correlation was observed between carcinoembryonic antigen and aortic stiffness index in the whole sample (r = 0.550, P < 0.001) and separately in females (r = 0.480, P < 0.001) and males (r = 0.602, P < 0.001). In multivariate stepwise regression analysis, female gender (r = -0.081, P < 0.001), age (r = 0.006, P < 0.001), BMI (r = 0.007, P = 0.002), and carcinoembryonic antigen (r = 0.375, P < 0.001) were determined as the strongest independent variables associated with aortic stiffness. When the model was adapted separately for females and males, age and carcinoembryonic antigen were determined as independent variables for aortic stiffness in both genders. CONCLUSION: Carcinoembryonic antigen level is associated with aortic stiffness in healthy individuals. However, the clinical significance of this relationship is unknown.

The Relationship Between Carcinoembryonic Antigen and Epicardial Adipose Tissue

Abstract Background: Inflammation, which is associated with an unhealthy lifestyle, plays a critical role in the development of both cardiometabolic diseases (CMD) and cancer. Carcinoembryonic antigen (CEA) is a tumor marker which also has proinflammatory properties. Recent studies have reported CEA to be associated with atherosclerosis, metabolic syndrome, and visceral adiposity. Epicardial adipose tissue (EAT) can exhibit highly inflammatory and pathogenic properties, and is a known risk factor for CMD. However, its relationship with CEA is still unknown. Objectives: This study aimed to investigate the possible association of CEA with EAT. Methods: A total of 134 Caucasian (males = 56, females = 78) individuals, aged (22-83 years), who were admitted for routine health control, were enrolled in this cross-sectional study. CEA was measured with chemiluminescent microparticle immunoassay (CMIA). EAT was measured by transthoracic echocardiography, and the visceral fat rating (VFR) was assessed by a body composition analyzing machine. The p-value <0.05 was considered statistically significant. Results: CEA levels were categorized as tertiles: T1, 0.5-1.04; T2, 1.06-1.69; and T3, ≥1.7 ng/ml. The mean age, weight, VFR, EAT, and fasting glucose, as well as the median of systolic blood pressure (SBP), creatinine, and AST increased with the increasing CEA tertiles. CEA was significantly associated with EAT (r = 0.55, P<0.001) and VFR (r = 0.36, P<0.001). Multivariate linear regression analysis confirmed that gender, age, and EAT were the significant independent variables associated with CEA. Conclusion: Individuals with increased EAT have higher levels of CEA, suggesting that this biomarker is most likely produced by EAT; however, additional investigations are required to improve the present work.

Comparação das Novas Equações de Martin/Hopkins e Sampson para o Cálculo do Colesterol de Lipoproteína de Baixa Densidade em Pacientes Diabéticos / Comparison of Novel Martin/Hopkins and Sampson Equations for Calculation of Low-Density Lipoprotein Cholesterol in Diabetic Patients

Resumo Fundamentos A determinação precisa do colesterol de lipoproteína de baixa densidade (LDL-C) é importante para se alcançar concentrações de LDL-C recomendadas por diretrizes e para reduzir resultados cardiovasculares adversos em pacientes diabéticos. A equação de Friedewald comumente usada (LDL-Cf) produz resultados imprecisos em pacientes diabéticos devido a dislipidemia diabética associada. Recentemente, duas novas equações - Martin/Hopkins (LDL-CMH) e Sampson (LDL-Cs) - foram desenvolvidas para melhorar a precisão da estimativa de LDL-C, mas os dados são insuficientes para sugerir a superioridade de uma equação sobre a outra. Objetivos O presente estudo comparou a precisão e a utilidade clínica das novas equações de Martin/Hopkins e Sampson em pacientes diabéticos. Método Foram incluídos no estudo quatrocentos e dois (402) pacientes com diabetes. O risco cardiovascular dos pacientes e as metas de LDL-C foram calculadas por diretrizes europeias. As concentrações de LDL-Cmh, LDL-Cs, e LDL-Cf calculadas foram comparadas à concentração de LDL-C direto (LDL-Cd) para testar a concordância entre essas equações e LDL-Cd. Um P valor <0,05 foi aceito como estatisticamente significativo. Resultados A LDL-CMH e a LDL-Cs tiveram concordância melhor com o LDL-Cd em comparação com a LDL-Cf, mas não houve diferenças estatísticas entre as novas equações para concordância com o LDL-Cd (Alfa de Cronbach de 0,955 para ambos, p=1). Da mesma forma, a LDL-CMH e a LDL-Cs tinham um grau semelhante de concordância com o LDL-Cd para determinar se o paciente estava dentro da meta de LDL-C (96,3% para LDL-Cmh e 96,0% para LDL-Cs), que eram ligeiramente melhores que a LDL-Cf (94,6%). Em pacientes com uma concentração de triglicérides >400 mg/dl, a concordância com o LDL-Cd foi ruim, independentemente do método usado. Conclusão As equações de Martin/Hopkins e Sampson mostram uma precisão similar para o cálculo de concentrações de LDL-C nos pacientes com diabetes, e ambas as equações são ligeiramente melhores que a equação de Friedewald.

Abstract Background The accurate determination of low-density lipoprotein cholesterol (LDL-C) is important to reach guideline-recommended LDL-C concentrations and to reduce adverse cardiovascular outcomes in diabetic patients. The commonly used Friedewald equation (LDL-Cf), gives inaccurate results in diabetic patients due to accompanying diabetic dyslipidemia. Recently two new equations - Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) - were developed to improve the accuracy of LDL-C estimation, but data are insufficient to suggest the superiority of one equation over the other one. Objective The present study compared the accuracy and clinical usefulness of novel Martin/Hopkins and Sampson equations in diabetic patients. Methods This study included 402 patients with diabetes. Patients' cardiovascular risk and LDL-C targets were calculated per European guidelines. Calculated LDL-Cmh, LDL-Cs, and LDL-Cf concentrations were compared with direct LDL-C concentration (LDL-Cd) to test agreement between these equations and LDL-Cd. A p-value <0.05 was accepted as statistically significant. Results Both LDL-Cmh and LDL-Cs had a better agreement with LDL-Cd as compared to LDL-Cf, but no statistical differences were found among novel equations for agreement with LDL-Cd (Cronbach's alpha 0.955 for both, p=1). Likewise, LDL-Cmh and LDL-Cs showed a similar degree of agreement with LDL-Cd in determining whether a patient was in a guideline-recommended LDL-C target (96.3% for LDL-Cmh and 96.0% for LDL-Cs), which were marginally better than LDL-Cf (94.6%). In patients with a triglyceride concentration >400 mg/dl, agreement with LDL-Cd was poor, regardless of the method used. Conclusion Martin/Hopkins and Sampson's equations show a similar accuracy for calculating LDL-C concentrations in patients with diabetes, and both equations were marginally better than the Friedewald equation.

Transcutaneous Puncture and Successfully Retrieval of Undeflated Peripheral Angioplasty Balloon.

Percutaneous transluminal angioplasty has gained increasing popularity in the treatment of peripheral artery disease. However, the increase in the frequency of this procedure also increases the risk of complications. Percutaneous transluminal angioplasty has serious and general complications in terms of device and technique at puncture and dilatation sites. In this case, we describe the easy and practical management of deflating an undeflated ballon in the right superficial femoral artery.

Lack of right ventricular hypertrophy is associated with right heart failure in patients with left ventricular failure.

Presence of right heart failure (RHF) is associated with a worse prognosis in patients with left ventricular failure (LVF). While the cause of RHF secondary to LVF is multifactorial, an increased right ventricular (RV) afterload is believed as the major cause of RHF. However, data are scarce on the adaptive responses of the RV in patients with LVF. Our aim was to understand the relationship of right ventricular hypertrophy (RVH) with RHF and RV systolic and diastolic properties in patients with LVF. 55 patients with a left ventricular ejection fraction of 40% or less were included in the present study. A comprehensive two-dimensional transthoracic echocardiographic examination was done to all participants. 12 patients (21.8%) had RHF, and patients with RHF had a significantly lower right ventricular free wall thickness (RVFWT) as compared to patients without RHF (5.3 ± 1.7 mm vs. 6.6 ± 0.9 mm, p = 0.02) and the difference remained statistically significant after adjusting for confounders (Δx̅:1.34 mm, p = 0.002). RVFWT had a statistically significant correlation with tricuspid annular plane systolic excursion (r = 0.479, p < 0.001) and tricuspid annular lateral systolic velocity (r = 0.360, p = 0.007), but not with the indices of the RV diastolic function. None of the patients with concentric RVH had RHF, while 22.2% of patients with eccentric RVH and 66.7% of patients without RVH had RHF (p < 0.01 as compared to patients with concentric RVH). In patients with left ventricular systolic dysfunction, absence of RVH was associated with worse RV systolic performance and a significantly higher incidence of RHF.

Peripheral neural blockade for pain control in patients undergoing percutaneous angioplasty for complex infrapopliteal disease.

In recent years, percutaneous transluminal angioplasty has become the preferred revascularization option for chronic limb-threatening ischemia (CLTI) and infrapopliteal (IP) arterial disease. CLTI and IP disease require complex and lengthy procedures that necessitate multiple balloon inflations and frequent contrast injections. It will lead to severe discomfort if periprocedural pain control is inadequate. Conventional methods such as local anesthesia and systemic opioids are usually inadequate to provide pain control for complex IP arterial disease interventions. Ultrasound-guided peripheral nerve blockade (PNB) has been recently employed in peripheral procedures, with several small studies reporting favorable results in patients who underwent not complex interventions. In the present series, we report our experience of 4 patients who underwent PNB to relieve pain during endovascular treatment of complex IP disease, and in whom we have observed excellent periprocedural pain control that led to satisfactory postprocedural outcomes.

Usefulness of novel Martin/Hopkins and Sampson equations over Friedewald equation in cardiology outpatients: A CVSCORE-TR substudy.

BACKGROUND AND AIMS: The Friedewald equation (LDL-Cf) is known to produce inaccurate estimations of low-density lipoprotein cholesterol (LDL-C) when triglycerides are high (>400 mg/dL) or LDL-C is low (<70 mg/dL). The Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) equations were developed to overcome these limitations, but few data are available to assess whether these equations offer incremental usefulness over LDL-Cf. Our aim was to understand whether there was any incremental usefulness of novel equations on decisions regarding patient management. METHODS: Four thousand one hundred and ninety-six cardiology patients who were included in a multicentre registry database were analysed. Each patient was assigned to a cardiovascular risk class using the SCORE (Systematic COronary Risk Evaluation) algorithm, and relevant European guidelines were used to assess LDL-C targets. RESULTS: Compared with LDL-Cmh and LDL-Cs, LDL-Cf was able to correctly identify 96.9%-98.08% of patients as within or outside the LDL-C target, respectively, and 1.95%-2.8% of patients were falsely identified as being within the LDL-C target. Kappa coefficients for agreement between LDL-Cf vs LDL-Cmh and LDL-Cf vs LDL-Cs were 0.868 and 0.918 (P < .001). For patients not on cholesterol-lowering drugs, the decision to initiate treatment would be different in 1.2%-1.8% of cases if LDL-Cs or LDL-Cmh were used, respectively. For those already on cholesterol-lowering drugs, decisions regarding treatment intensification would be different in 1.5%-2.4% of cases if LDL-Cs or LDL-Cmh were used. CONCLUSIONS: In most cardiology outpatients, the Friedewald equation has excellent agreement with the novel Martin/Hopkins and Sampson equations, and treatment decisions should not change in most patients.

Red Cell Distribution Width with CHADS2 and CHA2DS2-VASc score is associated with Post-operative Atrial Fibrillation after Coronary Artery Bypass Grafting.

BACKGROUND: The use of the CHA2DS2-VASc scoring system and red cell distribution width (RDW) as post-op Atrial Fibrillation (POAF) predictors may be promising for the identification of patients that are at a higher risk of POAF. METHODS: A total of 358 patients (57 patients with POAF, and 301 patients with non-POAF ) with sinus rhythm undergoing a coronary artery bypass graft (CABG) operation were included in the study retrospectively. Preoperative RDW levels and electrocardiograms with sinus rhythm were recorded. Patients with at least one 12-lead electrocardiogram with atrial fibrillation in the postoperative period, with or without medical or electrical cardioversion, were considered to have postoperative atrial fibrillation. A CHADS2 and CHA2DS2-VASc score was calculated for all of the patients. RESULTS: RDW levels were significantly higher in POAF group. RDW levels were significantly correlated with CHADS2 ( r = 0.15, P = .007) and CHA2DS2-VASc (r = 0.19 P = .0001) scores. CHA2DS2-VASc scores were significantly higher in patients with POAF, whereas CHADS2 scores did not differ between groups. In multivariate analysis, left atrial diameter (LAD) (OR:2.44 [95% CI 1.16 - 5.1], P = .018), age (OR:1.04 [95% CI 1.01 - 1.08], P = .01), and RDW (OR:1.16 [95% CI 1.0 - 1.36], P = .05) were found to be predictive for POAF. The area under the receiver-operating characteristic curve of RDW was 0.65 (0.57 - 0.72, P = .0001) with 68.4% sensitivity and 51.2 % specificity to predict POAF. CONCLUSION: Our study showed that age, LAD, and the reduced probability of RDW are predictors of POAF, and that RDW is strongly associated with the thromboembolic risk as determined by CHADS2 and CHA2DS2-VASc scores.

Spontaneous embolization of an atrial septal defect occluder device into the left ventricular outflow tract in a patient with pulmonary stenosis.

A 24-year-old man was admitted to our outpatient clinic for his routine checkup of consecutively percutaneously treated atrial septal defect (ASD) and pulmonary valvular stenosis 45 days ago. A 24 mm ASD occluder device was implanted under transthoracic echocardiographic guidance and 80 mm Hg peak-to-peak pulmonary valvular gradient decreased to 20 mm Hg gradient after pulmonary valve dilatation with 23 mm NUMED II transluminal valvuloplasty catheter balloon. Atrial septal defect (ASD) closure is now routinely performed using a percutaneous approach under echocardiographic guidance especially transthoracic echocardiography (TEE). Centrally located, ostium secundum type and less than 3.5 cm in size are considered ideal for device closure. Although there is considerable variation in size and location of the defects, TEE guidance is quite important for this proportion of ASDs. The selection of patients for percutaneous transcatheter closure of a secundum ASD requires accurate information regarding the anatomy of the defect such as its maximal diameter and the amount of circumferential tissue rims.

A rare complication of mechanical aortic valve replacement: Separation in the region of the mitral-aortic intervalvular fibrosa.

A 28-year-old man was admitted to our emergency service with a shortness of breath and palpitation. On admission, his blood pressure was high and he was in hypertensive pulmonary edema. His physical examination showed rales in both lungs and pansystolic murmur at mitral focus. His medical history included aortic valve replacement (AVR) because of native aortic valve infective endocarditis. Transthoracic echocardiography (TTE) showed normal functional aortic valve. Color flow imaging demonstrated severe mitral regurgitation with posterior eccentric jet. To examine in detail, transesophageal echocardiography (TEE) and three-dimensional (3D) echocardiography were performed. TEE disclosed a separation in the subaortic curtain leading to severe mitral regurgitation from the left ventricle to the left atrium. In addition to severe mitral regurgitation with posterior eccentric jet, 26-mm-long pouch was seen in mitral-aortic intervalvular fibrosa (MAIVF) at 120° TEE view. This pouch was separated from the mitral anterior leaflet junction releasing the mitral anterior leaflet and causing prolapse and chorda rupture in the A2 scallop of the mitral anterior leaflet. The MAIVF connects the anterior mitral leaflet to the posterior portion of the aortic annulus. The separation of the MAIVF represents a complication of the aortic valve replacement.
