Predictive Value of the Modified Mehran Score for Contrast-Induced Nephropathy After Transcatheter Aortic Valve Implantation.

Considering the increasing use of the transcatheter aortic valve implantation (TAVI) procedure, the relationship of contrast-induced nephropathy (CIN) with post-TAVI mortality has become important. The Mehran score was developed to detect the risk of CIN development after cardiac intervention. We aimed to compare the role of the modified Mehran score, which can be calculated pre-procedure, in predicting CIN development and compare it with the original Mehran score. We retrospectively collected data from TAVI procedures at our institution between December 2016 and June 2021; of 171 patients, 44 (25.7%) had CIN. We found no association between contrast media volume and CIN (387 ± 120 vs 418 ± 139 mL, P = .303). High and very high modified Mehran score and preoperative C-reactive protein (CRP) level were independent risk factors for CIN development after TAVI procedure. The area under curve (AUC) was .686 with 95% CI: .591-.780 and P < .001, and also, with a cut-off point of >7.5 points, there was 79.5% sensitivity and 63.0% specificity; otherwise, with a cut-off point of >9.5 points, there was 54.5% sensitivity and 71.7% specificity, for the modified Mehran score. The modified Mehran score comes into prominence compared with the original Mehran score since it can be calculated pre-procedure.

Monocyte to HDL ratio may predict thrombosis in patients with mechanical mitral and aortic valve prosthesis.

Increased inflammatory biomarkers have been reported in prosthetic heart valve thrombosis (PHVT). Monocyte to HDL ratio (MHR) and albumin to CRP levels (CAR) are two biomarkers used widely for systemic inflammation but there is a lack of data on prosthetic heart valves. This study aimed to find out the potential predictive value of MHR and CAR for PHVT. Patients who had the diagnosis of mechanical mitral/aortic PHVT and normally functioning prosthesis were retrospectively analyzed. Laboratory data including complete blood count and biochemistry were recorded. Transesophageal echocardiography was performed to diagnose PHVT. The study included 118 patients with mechanical PHVT and 120 patients with normally functioning prosthesis. White blood count, monocyte levels, C-reactive protein, MHR and CAR were significantly higher whereas the lymphocyte, HDL and INR levels on admission were lower in patients with PHVT. Multivariate analysis showed that as well as inadequate anticoagulation, MHR, but not CAR, was found to be an independent predictor of thrombosis in patients with PHVT. Receiver operating characteristic curve analysis was performed to detect the best cut-off value of MHR in the prediction of thrombosis in patients with prosthetic valves. MHR level of > 12.8 measured on admission, yielded an AUC value of 0.791 [(CI 95% 0.733-0.848 p < 0.001) sensitivity 71%, specificity 70%]. Inadequate anticoagulation is the primary cause that leads to thrombosis in mechanical prosthetic valves. Increased MHR, but not CAR, was also shown to be an independent predictor of thrombosis in patients with mechanical mitral and aortic prosthetic valves.

Strain Echocardiographic Evaluation of Myocardial Involvement in Patients with Continuing Chest Pain after COVID-19 Infection. / Avaliação Ecocardiográfica com Strain do Envolvimento Miocárdico em Pacientes com Dor Torácica Contínua após Infecção por COVID-19.

BACKGROUND: A new clinical manifestation called post or long coronavirus disease (p/l COVID) has walked into our lives after the acute COVID-19 phase. P/l COVID may lead to myocardial injury with subsequent cardiac problems. Diagnosing these patients quickly and simply has become more important due to the increasing number of patients with p/l COVID. OBJECTIVES: We compared strain echocardiography (SE) parameters of patients who suffered from atypical chest pain and had sequel myocarditis findings on cardiac magnetic resonance (CMR). We aimed to investigate the value of SE for detection of myocardial involvement in patients with p/l COVID. METHODS: A total of 42 patients were enrolled. Our population was separated into two groups. The CMR(-) group (n = 21) had no myocardial sequelae on CMR, whereas the CMR(+) group had myocardial sequelae on CMR (n = 21). The predictive value of SE for myocarditis was also evaluated by age-adjusted multivariate analysis. P values < 0.05 were considered statistically significant. RESULTS: When compared with left ventricular ejection fraction (LVEF), global longitudinal strain (GLS) and global circumferential strain (GCS) had a stronger relationship (LVEF, p = 0.05; GLS, p < 0.001; GCS, p < 0.001) with p/l COVID associated myocardial involvement. GLS < 20.35 had 85.7% sensitivity and 81% specificity; GCS < 21.35 had 81% sensitivity and 81% specificity as diagnostic values for myocardial sequelae detected with CMR. While there was no difference between the groups in terms of inflammatory markers (C-reactive protein, p = 0.31), a difference was observed between biochemical markers, which are indicators of cardiac involvement (brain natriuretic peptide, p < 0.001). CONCLUSION: SE is more useful than traditional echocardiography for making diagnosis quickly and accurately in order not to delay treatment in the presence of myocardial involvement.

FUNDAMENTO: Tem surgido uma nova manifestação clínica chamada pós-COVID ou COVID longa (COVID p/l) após a fase aguda da COVID-19. COVID p/l pode levar à lesão miocárdica com problemas cardíacos subsequentes. Diagnosticar esses pacientes de forma rápida e simples é cada vez mais importante devido ao número crescente de pacientes com COVID p/l. OBJETIVOS: Comparamos os parâmetros de ecocardiografia com strain (ES) de pacientes que apresentaram dor torácica atípica e achados de sequelas de miocardite na ressonância magnética cardíaca (RMC). Nosso objetivo foi investigar o valor da ES para detecção de envolvimento miocárdico em pacientes com COVID p/l. MÉTODOS: Foram incluídos um total de 42 pacientes. Nossa população foi separada em 2 grupos. O grupo RMC(-) (n = 21) não apresentou sequelas miocárdicas na RMC, enquanto o grupo RMC(+) apresentou sequelas miocárdicas na RMC (n = 21). O valor preditivo da ES para miocardite também foi avaliado por análise multivariada ajustada por idade. Valores de p < 0,05 foram considerados estatisticamente significativos. RESULTADOS: Quando comparado com a fração de ejeção do ventrículo esquerdo (FEVE), o strain longitudinal global (SLG) e o strain circunferencial global (SCG) tiveram uma relação mais forte (FEVE, p = 0,05; SLG, p < 0,001; SCG, p < 0,001) com envolvimento miocárdico associado à COVID p/l. SLG < 20,35 apresentou sensibilidade de 85,7% e especificidade de 81%; SCG < 21,35 apresentou sensibilidade de 81% e especificidade de 81% como valores diagnósticos para sequelas miocárdicas detectadas com RMC. Enquanto não houve diferença entre os grupos quanto aos marcadores inflamatórios (proteína C-reativa, p = 0,31), houve diferença entre os marcadores bioquímicos, que são indicadores de envolvimento cardíaco (peptídeo natriurético cerebral, p < 0,001). CONCLUSÃO: A ES é mais útil do que a ecocardiografia tradicional para diagnosticar com rapidez e precisão, a fim de não atrasar o tratamento na presença de envolvimento miocárdico.

The Clinical Value of the Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy Score in Predicting Long-Term Major Adverse Cardiovascular And Cerebrovascular Events and Major Bleeding in Acute Coronary Syndrome Patients Who Underwent Percutaneous Coronary Intervention.

The PRECISE-DAPT (predicting bleeding complications in patients undergoing stent implantation and subsequent dual antiplatelet therapy) score is recommended for predicting out-of-hospital bleeding after percutaneous coronary intervention (PCI). However, its long-term prediction remains unclear. We investigated the performance of this score in predicting long-term outcomes in patients with the acute coronary syndrome (ACS). We divided retrospectively enrolled patients (n = 1071) into two groups according to their PRECISE-DAPT scores: low < 25 and high ≥ 25. Bleeding was assessed using the Bleeding Academic Research Consortium criteria. The ischemic endpoints were all-cause death and major adverse cardiovascular and cerebrovascular events (MACCE). During follow-up (median 7.3 years), MACCE (55 vs 35%, P<.001) and major bleeding (9 vs 4%, P = .002) rates were greater in the high score group. The PRECISE-DAPT score was an independent predictor of MACCE in multivariate analysis (Hazard ratio [HR]: 1.028, 95% confidence interval [CI]: 1.016-1.039, P < .001). Also, the PRECISE-DAPT score predicted all-cause mortality (HR: 2.115, 95% CI: 1.508-2.965, P < .001) at long-term follow-up. The PRECISE-DAPT score may be useful for predicting MACCE at long-term follow-up in addition to the risk of bleeding.

Determinants of Coronary Angiography in Non-ST-elevation Myocardial Infarction with Low Ejection Fraction.

OBJECTIVE: To investigate the clinical and demographic factors affecting the selection of angiography in patients with severe left ventricular systolic dysfunction (SLVSD, ejection fraction lower than 30%) developing non-ST-segment elevation (NSTEMI). STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: This study was conducted at the Department of Cardiology, School of Medicine, Izmir Katip Celebi University, Izmir, Turkey, between March 2018 and March 2021. METHODOLOGY: Patients with SLVSD (Ejection fraction <30%) developing Clinical and demographic factors were compared between the patients who were or were not decided for angiography. Associated factors for the decision of angiography were evaluated. RESULTS: Overall, 68 (46%) out of 147 patients underwent coronary angiography. Angiography led to coronary artery bypass grafting (CABG) in 14 (21%), percutaneous coronary intervention (PCI) in 30 (44%), and medical treatment in 24 (35%). Among the patients who decided for CABG, 10 (71%) underwent surgery. In multivariate analysis; Killip score ≥2 [Odds ratio (OR) :33.85, 95% Confidence Interval (CI): 5.03-227.405 p<0.001], lower education level (OR: 17.66, 95% CI: 2.25-138.44, p=0.006), anaemia (OR: 10.60, 95% CI: 2.07-54.28, p=0.005), age ≥65 years (OR: 7.124, 95% CI: 1.33-38.12, p=0.02), and PCI history (OR: 0.132, 95% CI: 0.02-0.84, p=0.032) were associated factors with the decision of only medical treatments instead of angiography. CONCLUSION: Demographic factors such as age and education level and clinical factors such as decompensation, PCI history, and anaemia significantly affect the decision of angiography in the patients with SLVSD and NSTEMI. KEY WORDS: Heart failure, NSTEMI, Revascularisation, Severe left ventricular systolic dysfunction, Ejection fraction.

Accuracy of Multi-organ Point-of-Care Ultrasound for Acute Kidney Injury Etiologies.

This study investigated the diagnostic performance of point-of-care ultrasound (POCUS) for acute kidney injury (AKI) etiological subgroups in emergency department (ED) patients. Multi-organ POCUS including kidney, bladder, inferior vena cava (IVC), lung and cardiac examinations were used to identify five AKI subgroups: hypovolemia, reduced cardiac output, systemic vasodilatation and renal vasomodulation, renal and post-renal. One hundred sixty-five AKI patients were included in the study. The most diagnostic parameter in the post-renal group was the presence of any hydronephrosis, with a sensitivity of 93.3% (95% confidence interval [CI]: 68.1-99.8) and specificity of 85.9% (95% CI: 79.3-91.1). For the reduced cardiac output group, the most diagnostic parameter was IVC maximum diameter >17 mm with a sensitivity of 100% (95% CI: 83.2-100) and specificity of 70.2% (95% CI: 61.6-77.7). For the hypovolemia group, the most diagnostic parameter was IVC maximum diameter ≤17.9 mm with a sensitivity of 81.2% (95% CI: 71.2-88.8) and specificity of 56.5% (95% CI: 44-68.4). For the systemic vasodilatation and renal vasomodulation group, the most diagnostic parameter was diffuse ascites with a sensitivity of 56.3% (95% CI: 29.9-80.2) and specificity of 89.9% (95% CI: 83.8-94.2). None of the parameters were significant for the renal group. We concluded that multi-organ POCUS is of diagnostic value for AKI subgroups.

Platelet distribution width in young patients with chronic venous insufficiency.

OBJECTIVE: Platelet distribution width (PDW) has been reported in a wide range of pathological settings. In this study, we aimed to investigate the relationship between PDW and lower extremity chronic venous insufficiency (CVI) by comparing the levels of PDW and other parameters derived from complete blood count (CBC) tests in young individuals with or without lower extremity CVI. METHODS: This prospective clinical study was conducted between January 2020 and December 2020. A total of 108 patients, 72 patients with lower extremity CVI (study group) and 36 healthy volunteers (control group) were enrolled from the Bursa Yuksek Ihtisas Education Research Hospital and the Bolu Abant Izzet Baysal University Training and Research Hospital. The age range of the participants was between 18 and 50 years old. Participants' baseline clinical features and CBC parameters including PDW, white blood cell, hemoglobin, hematocrit, mean corpuscular volume, red cell distribution width, neutrophil, lymphocyte, platelet count, mean platelet volume, plateletcrit, neutrophil-to-lymphocyte ratio, and platelet-to-lymphocyte ratio were compared between the two groups. RESULTS: The groups were statistically similar in terms of baseline clinical features. The median PDW value was significantly higher for the CVI patients relative to the control group (17.6 vs 16.8; p < 0.001). In terms of other CBC parameters, there were no significant differences between the groups. According to ROC analysis, area under the curve of PDW was 0.749 (95% confidence interval: 0.653-0.846 and p < 0.001). If the value of PDW was accepted as 17, it could predict CVI with 76% sensitivity and 59% specificity, whereas a PDW value of 17.5 could predict CVI with 51% sensitivity and 81% specificity. CONCLUSION: Platelet distribution width might be a useful marker to determine an increased inflammatory response and thrombotic status in young patients with CVI.

Is coronary artery tortuosity a predisposing factor for drug-eluting stent restenosis?

BACKGROUND: Coronary artery tortuosity (CAT) is a relatively common finding on coronary angiography and may be associated with impaired left ventricular relaxation and coronary ischemia However, the significance of CAT remains unknown. This study aimed to investigate whether the severity of tortuosity in the targeted coronary segment is a predictor of stent restenosis. METHODS: The study included a total of 637 patients undergoing drug-eluting stent implantation due to stable or unstable angina and who had no native coronary artery stenosis on their last coronary angiogram. The patients were separated into two groups: 312 patients with in-stent restenosis and 325 patients without in-stent restenosis. All patients underwent computed tomography (CT) coronary angiography after invasive angiography and CAT was calculated using the computer software. RESULTS: Patients with in-stent restenosis had higher CAT than those without restenosis (1.25 ± 0.11 vs. 1.11 + 0.07, p < 0.001). Multivariate Cox regression analysis showed that the tortuosity index (hazard ratio [HR]: 1.246 95% confidence interval [CI]: 1.127-1.376 p < 0.001) and the circumflex lesion (HR: 1.437 95% CI: 1.062-1.942 p = 0.019) were independently associated with in-stent restenosis. With the threshold value of severe tortuosity set at 1.15, the prediction of could be made with 81% sensitivity and 80% specificity. CONCLUSION: The severity of tortuosity is proportional to coronary in-stent stenosis in patients with stable and unstable angina pectoris undergoing drug-eluting stent implantation for a severe single coronary artery.

Kinesiophobia, physical performance, and health-related quality of life in patients with coronary artery disease.

Introduction: Kinesiophobia is an important risk factor for physical activity and exercise restrictions. It is important to assess kinesiophobia and identify high-risk patients to help prevent sedentary behaviour and increase exercise participation among cardiac patients. Aim: To evaluate kinesiophobia and its association with physical performance, health-related quality of life (HRQOL), patients' limitations and symptoms, and disease history in patients with coronary artery disease (CAD). Material and methods: Fifty-two patients diagnosed with CAD were enrolled in this study. Kinesiophobia was assessed with the Tampa Scale of Kinesiophobia for Heart. The 5× Sit-to-Stand Test (5-STST), the Timed Up and Go Test (TUGT), and the 6-Minute Walk Test (6-MWT) were used to assess physical performance. Patients' limitations and symptoms and HRQOL were evaluated with the Cardiovascular Limitations and Symptoms Profile. CAD duration and history of myocardial infarction (MI) were also recorded. Results: 87.2% of the patients had high level of kinesiophobia, which was higher in patients with previous MI compared to patients without history of MI (p = 0.031). Kinesiophobia was positively correlated with 5-STST duration, TUGT duration, angina, shortness of breath, HRQOL, and CAD duration, and it was negatively correlated with 6-MWT distance (p < 0.05). According to regression analysis, only angina was a significant predictor for kinesiophobia (p = 0.014). Kinesiophobia was found to be a predictor of physical performance and HRQOL (p < 0.05). Conclusions: Levels of kinesiophobia are high in patients with CAD, especially in those with a history of MI. Angina is a predictor of kinesiophobia while kinesiophobia is a predictor of both physical performance and HRQOL in CAD patients.

Association between Intermountain Risk Score and long-term mortality with the transcatheter aortic valve implantation procedure.

BACKGROUND: Since its first introduction, the spectrum and frequency of use of transcatheter aortic valve implantation (TAVI) have increased throughout the world. Therefore, it is crucial to determine which patients are at high mortality risk with TAVI. The Intermountain Risk Score (IMRS) is a score calculated from laboratory parameters. This study aimed to determine the long-term mortality of TAVI patients using the IMRS and to compare it with traditional scoring systems. METHODS: The study included a total of 133 patients undergoing TAVI at our hospital from 2010 to 2019. Demographic data, co-morbid diseases, echocardiographic and laboratory parameters were collected retrospectively. The performance of IMRS was assessed as compared to the mortality determined in the overall patient population. RESULTS: During the follow-up, 54.9% of patients (60 patients) (Group 1) survived; the mortality in Group 2 (60 patients) was 45.1%. The survival period had a mean of 1433 (±124) days. The mean IMRS was 1.67 (0.7) in Group 1 and 2.33 (0.72) in Group 2 (P <0.001). In multivariable analyses, only high risk of IMRS (hazard ratio [HR], 3.430; 95% confidence interval [CI], 1.537-7.653; P = 0.003) and EuroSCORE II (HR, 1.141; 95% CI, 1.011-1.288; P = 0.03) independently predicted long-term mortality. CONCLUSIONS: From the evaluation of all laboratory and echocardiography parameters, long-term mortality (>30 days) following the TAVI procedure can be said to be higher in patients with a high IMRS. The data from this study can be considered of value in demonstrating the clinical significance of IMRS calculation before the TAVI procedure.

Identification of Circulating Diagnostic Biomarkers for Coronary Microvascular Disease in Postmenopausal Women Using Machine-Learning Techniques.

Coronary microvascular disease (CMD) is a common form of heart disease in postmenopausal women. It is not due to plaque formation but dysfunction of microvessels that feed the heart muscle. The majority of the patients do not receive a proper diagnosis, are discharged prematurely and must go back to the hospital with persistent symptoms. Because of the lack of diagnostic biomarkers, in the current study, we focused on identifying novel circulating biomarkers of CMV that could potentially be used for developing a diagnostic test. We hypothesized that plasma metabolite composition is different for postmenopausal women with no heart disease, CAD, or CMD. A total of 70 postmenopausal women, 26 healthy individuals, 23 individuals with CMD and 21 individuals with CAD were recruited. Their full health screening and tests were completed. Basic cardiac examination, including detailed clinical history, additional disease and prescribed drugs, were noted. Electrocardiograph, transthoracic echocardiography and laboratory analysis were also obtained. Additionally, we performed full metabolite profiling of plasma samples from these individuals using gas chromatography-mass spectrometry (GC-MS) analysis, identified and classified circulating biomarkers using machine learning approaches. Stearic acid and ornithine levels were significantly higher in postmenopausal women with CMD. In contrast, valine levels were higher for women with CAD. Our research identified potential circulating plasma biomarkers of this debilitating heart disease in postmenopausal women, which will have a clinical impact on diagnostic test design in the future.

Evaluation of Bleeding Rate and Time in Therapeutic Range in Patients Using Warfarin Before and During the COVID-19 Pandemic-Warfarin Treatment in COVID-19.

The treatment process of patients using warfarin is expected to be hindered during the COVID-19 pandemic. Therefore we investigated whether the time in therapeutic range (TTR) and bleeding complications were affected during the COVID-19 pandemic. 355 patients using warfarin were included between March 2019 to March 2021. Demographic parameters, INR (international normalized ratio), and bleeding rates were recorded retrospectively. The TTR value was calculated using Rosendaal's method. The mean age of the patients was 61 ± 12 years and 55% of them were female. The mean TTR value during the COVID-19 pandemic was lower than the pre-COVID-19 period (56 ± 21 vs 68 ± 21, P < 0.001). Among the patients, 41% had a lack of outpatient INR control. During the COVID-19 pandemic, 71 (20%) patients using VKA suffered bleeding. Among patients with bleeding, approximately 60% did not seek medical help and 6% of patients performed self-reduction of the VKA dose. During the COVID-19 pandemic, TTR values have decreased with the lack of monitoring. Furthermore, the majority of patients did not seek medical help even in case of bleeding.

Platelet-Lymphocyte ratio is a predictor for the development of no-reflow phenomenon in patients with ST-segment elevation myocardial infarction after thrombus aspiration.

BACKROUND: We aimed to evaluate the utility of the preprocedural platelet-lymphocyte ratio (PLR) for predicting the no-reflow phenomenon after thrombus aspiration during percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI). METHOD: We retrospectively analyzed postprocedural thrombolysis in myocardial infarction (TIMI) flow grades and myocardial blush grades (MBG) of 247 patients who underwent a PCI procedure with thrombus aspiration.We divided these patients into two groups according to whether they had no-reflow (TIMI < 3, MBG < 2) or not (TIMI 3, MBG ≥ 2). RESULTS: No-reflow developed in 43 (17%) patients.Preprocedural PLR was significantly higher in the no-reflow group (183.76 ± 56.65 vs 118.32 ± 50.42 p < 0.001).Independent predictors of no-reflow were as follows: higher preprocedural platelet-lymphocyte ratio (PLR) (OR = 1.018; 95% CI = 1.004, 1.033; p = 0.013),mean corpuscular volume (MCV) (OR = 1.118; 95% CI = 1.024, 1.220; p = 0.012) and SYNTAX Score-2 (OR = 1.073; 95% CI = 1.005, 1.146; p = 0.036). PLR of 144 had 79% sensitivity and 75% specificity for the prediction of no-reflow. CONCLUSION: PLR is a reliable predictor for no-reflow in STEMI patients undergoing thrombus aspiration.

Association between lower extremity venous insufficiency and duration of atrial fibrillation.

OBJECTIVE: Physiologic studies have shown that atrium has an active role in venous blood return from lower extremity. In this context we investigated the association between AF and chronic venous disease (CVD). METHODS: In this observational study we included 392 AF patients which were divided into two groups (chronic AF, 218 (56%)) and non-chronic. AF, 174 (44%)). These two groups were compared in terms of CVD after matching conventional risk factors for CVD. RESULTS: CEAP classification was different between chronic and non-chronic patients (C0-C2: 72% vs 47%; C3-C6: 28% vs 53% <0.001). Chronic AF patients had also higher rate of venous reflux on Doppler ultrasound (38% vs 16% P < 0.05). There was a correlation between AF duration, right atrial volume index and CEAP classification respectively (rho:0.314 p < 0.001), (rho:0.258, p < 0.001). CONCLUSION: Prevalence of CVD is higher in patients with chronic AF. In addition, atrial volume is directly correlated with CVD.

Association of Inflammatory Markers with Multisite Artery Disease in Patients with Peripheral Arterial Disease.

INTRODUCTION: Chronic inflammation plays a considerable role in atherosclerosis and may occur simultaneously in different arteries. This condition is referred to as multisite arterial disease (MSAD). We aimed to investigate the association between inflammatory markers and MSAD. METHODS: In this cross-sectional study we included 526 patients with peripheral artery disease (PAD). Patients with PAD were evaluated by conventional or computed tomography angiography for the presence of coronary artery disease (CAD) and those with at least 30% stenosis were included in the study. Patients were divided into two groups: either MSAD+(PAD and CAD), Group 1) or MSAD- (only PAD without CAD, Group 2). Inflammatory markers were compared between the two groups. RESULTS: Among all patients, 293 had MSAD while 233 had only PAD. The MSAD+group had higher neutrophil-to-lymphocyte ratio (NLR) and platelet-to-neutrophil ratio (PLR) (5.08±0.19, 4.67±0.51, and 207.1±6.23, 169.3±10.8, respectively, p<0.001). In multivariate analysis, HT [odds ratio (OR): 2.40 (1.61-3.59)); p<0.002], male gender [OR: 2.03 (1.29-3.17); p=0.002], DM [OR:1.56 (1.03-2.36); P=0.035], NLR [OR: 1,08 (1.02-1.16); p=0.021, and PLR [OR:1.05 (1.03-1.08); p<0.001] were found to be associated with MSAD. CONCLUSION: NLR and PLR are correlated with MSAD and may indicate the extent of atherosclerosis.

Analysis of thrombophilic gene mutations in coronary artery ectasia.

OBJECTIVE: Coronary artery ectasia (CAE) is defined as localized or diffuse dilatation in the coronary artery lumen of at least 1.5 times the diameter of adjacent healthy reference segments. The etiology of CAE is still unknown, but the most likely cause is atherosclerosis. The aim of this study was to evaluate several gene polymorphisms that are thought to have an effect on the development of coronary atherosclerosis and have been shown to cause thrombophilia in CAE patients. METHODS: The factor V Leiden (G1691A), factor V H1299R, prothrombin G20210A, factor XIII V34L, beta-fibrinogen-455 G>A, plasminogen activator inhibitor (PAI)-1 4G/5G, and methylenetetrahydrofolate reductase (MTHFR) C677T, and MTHFR A1298C polymorphisms were evaluated in 66 patients with CAE and 32 individuals with normal coronary arteries. RESULTS: Comparison of the CAE and control groups revealed that the clinical features and the frequency of polymorphism in the thrombophilic genes were similar in both groups. However, when heterozygous and/or homozygous polymorphism was compared between groups, it was found that there was a significantly higher finding of thrombophilic gene polymorphism in the CAE group (p=0.023). CONCLUSION: Thrombophilic gene polymorphism may be associated with the formation and clinical presentation of CAE.

The effect of successful parathyroid surgery on left ventricle function in patients with primary hyperparathyroidism evaluated with strain echocardiography.

BACKGROUND: Hyperparathyroidism (PHP) is the most common cause of hypercalcemia in outpatients. It is characterized by many cardiac complications including chronic cardiac arrhythmia, hypertrophy, and diastolic insufficiency. However, there are insufficient data about the cardiac systolic function in PHP. Data regarding the positive effects of surgical treatment on cardiac complications are limited and inadequate. The aim of this study was to evaluate the postoperative changes in the left ventricle functions of patients with PHP using strain echocardiography (STE) instead of traditional echocardiographic evaluation. METHODS: This prospective study included 29 patients with PHP. Detailed echocardiographic evaluations were made including conventional and STE' ventricle function preoperatively and at 6 months after surgery. Then, preoperative and postoperative STE changes, global longitudinal (GLS) and circumferential strain (GCS), were compared. Patients with recurrent surgery, poor echogenicity, and comorbid conditions affecting STE were excluded. RESULTS: No significant change was determined in ejection fraction in the period from preoperative to 6 months postoperative (P > .05). The GLS value increased from 18.53 ± 3.06 to 20.25 ± 3.89, to a statistically significant level (P = .004). The other echocardiographic parameters remained unchanged for the same patients. CONCLUSION: Despite normal 2D echocardiography data, it was determined that the GLS values deteriorated preoperatively and improved by the 6th postoperative month. The detection of early disorders in PHP that cannot be detected on 2D echocardiography, even in asymptomatic patients, may suggest a new treatment indication. For asymptomatic PHP patients, strain echocardiography may be more valuable than 2D echocardiographic evaluation to determine myocardial dysfunction. The recent literature is insufficient, and there is a need for further, more extensive studies with longer follow-up periods.

Correlation Between the Severity of Coronary Artery Ectasia and Monocyte/Lymphocyte, Platelet/Lymphocyte, and HDL/LDL Ratios.

OBJECTIVE: To evaluate the efficacy of the monocyte/lymphocyte, platelet/lymphocyte, and HDL/LDL ratios as markers of the severity of coronary artery ectasia(CE). STUDY DESIGN: Cross-sectional study. PLACE AND DURATION OF STUDY: Department of Cardiology, Izmir Katip Celebi University and Balikesir University, Turkey, from January 2017 to October 2018. METHODOLOGY: A total of 7,923 coronary angiographs were retrospectively scanned. Inclusion criteria was >1.5 times dilatated of native coronary artery segment. Exclusion criteria was <1.5 times or no dilatation of native coronary segment compared with normal coronary segment. Demographic features, CE type, clinic status, monocyte/lymphocyte, platelet/ lymphocyte and HDL/LDL ratios are collected. RESULTS: Two hundred and six (2.6%) cases were identified, which had a mean age of 61.4 ±11.4 years. The male to female ratio was 3:1; and 46% of the patients presented with unstable angina. The prevalence of CE was 2.6%; and 118 (57.2%) patients had non-obstructive coronary artery disease. Hypertension, hyperlipidemia and smoking were the most commonly seen disorders. Markis Type 4 was the most common type of CE determined. A statistically significant correlation was determined among the monocyte/lymphocyte ratio, platelet/lymphocyte ratio, and the increased diameter of ectasia of the vessel. CONCLUSION: Although there should be awareness of CE, many clinicians do not pay as much attention to CE as to coronary stenosis. The results of this study showed that the monocyte/lymphocyte ratio and platelet/lymphocyte ratio are consistent with the ectasia severity. This correlation will be useful for the evaluation of follow-up and treatment success in patients with CE.

Evaluation of subclinical myocardial dysfunction using speckle tracking echocardiography in patients with radiographic and non-radiographic axial spondyloarthritis.

OBJECTIVE: To evaluate whether there is any difference between radiographic axial spondyloarthritis (r-axSpA), also termed ankylosing spondylitis (AS), and non-radiographic (nr-) axSpA, with respect to subclinial myocardial dysfunction using speckle tracking echocardiography (STE). METHODS: This was a cross-sectional case control study. We included 72 patients with AS, 38 patients with nr-axSpA, and 56 age-matched healthy subjects. Patients with cardiac disease and cardiac risk factors affecting STE were excluded. The disease burden evaluated by the BASDAI, BASFI, BAS-G, and ASAS-HI scores were comparable in both the r- and nr-axSpA groups. A detailed echocardiographic examination including the M-mode, Doppler, and STE was applied to whole study population. RESULTS: Duration of the disease, the use of an anti-TNFα agent, and CRP levels were higher in patients with AS. Although the AS, nr-axSpA, and control groups had similar ejection fraction values (59±5.2, 60±4.6, 60±4.6, respectively, and p=0.499), the global longitudinal peak systolic strain (GLS) (20.5±3.3, 21.1±3.5, and 22.3±2.4, respectively, and p<0.05) was different between the groups. In a post-hoc analysis, GLS was not different between the nr-axSpA and control groups, and it was significantly lower in patients with AS. In the univariate analysis, peripheral arthritis (p=0.035) and age (p=0.032) were correlated with GLS. A multivariate regression analysis demonstrated that peripheral arthritis (p=0.009) was the only independent GLS predictor. CONCLUSION: Subclinical myocardial dysfunction as assessed by GLS was present in AS, but not in nr-ax-SpA patients. Thus, GLS could be used as a differentiating factor between radiographic and nr-axSpA patients.
