The association between CHA2DS2-VASc score and aortic valve sclerosis.

BACKGROUND: Antithrombotic therapy in atrial fibrillation is generally managed with the CHA2DS2-VASc score. Aortic valve sclerosis (AVS) is a focal thickening of the aortic valve without a restriction of motion. AVS is related to several cardiovascular risk factors. Our study was performed to evaluate whether the presence of AVS was associated with the CHA2DS2-VASc score. METHODS: This cross-sectional, observational study comprised 411 patients with AVS grades 1-3 [AVS (+)] and 102 patients with AVS grade 0 [AVS (-)]. We compared CHA2DS2-VASc scores between the AVS (+) and AVS (-) groups. RESULTS: We determined that the AVS (+) group had a higher CHA2DS2-VASc score than the AVS (-) group [3 (0-8) vs 1 (0-4), p < 0.001) ]. CONCLUSIONS: In our study, the CHA2DS2-VASc score was found to be higher in patients with AVS than in those without AVS. AVS may predict cardiovascular risk in the general population.

Venous leg symptoms, ecchymosis, and coldness in patients with peripheral varicose vein: A multicenter assessment and validation study (VEIN-VIOLET study).

OBJECTIVES: We aimed to evaluate peripheral varicose vein symptoms including ecchymosis and coldness by using the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms (VEINES-QoL/Sym) questionnaire. METHODS: A total of 1120 patients were enrolled to the analysis after the exclusion of 199 patients who did not match the inclusion criteria. Patients were asked to answer the VEINES-Sym questionnaire and questions about ecchymosis and coldness. Scores of ecchymosis and coldness were calculated similar to VEINES-Sym questionnaire. Classifications of peripheral varicose vein were made according to the clinical part of clinical, etiological, anatomical, and pathophysiological classification system and patients with grade 2 or higher were considered as positive for peripheral varicose vein. RESULTS: Frequency of symptoms present in the VEINES-Sym instrument, ecchymosis and coldness were significantly higher in patients with peripheral varicose vein. Mean score of each symptom was significantly lower in peripheral varicose vein patients including scores of ecchymosis and coldness. Logistic regression analysis revealed that presence of hemorrhoids and all symptoms in VEINES-Sym questionnaire except restless leg were significantly and independently associated with peripheral varicose vein. Besides, ecchymosis (odds ratio: 2.04, 95% confidence interval: 1.34-3.08, p = 0.008) but not coldness was significantly and independently associated with peripheral varicose vein. There was also significant correlation of VEINES-Sym score with ecchymosis (r = 0.43, p < 0.001) and coldness (r = 0.47, p < 0.001). CONCLUSIONS: Venous leg symptoms present in VEINES-Sym questionnaire except restless legs, presence of hemorrhoids and ecchymosis are significantly and independently associated with peripheral varicose vein. Not only ecchymosis but also coldness has shown an independent association with total VEINES-Sym score.

Hemolytic Anemia Due To Anti-c Incompatibility in The Newborn Period: A Case Report.

Hemolytic disease of the fetus and newborn is a disease that is caused by maternal alloantibodies to the fetus. In the literature, the frequency of hemolytic disease of the newborn due to Rh (D) sensitization decreased inversely with the increase in the use of anti-D gammaglobulin. However, the importance of minor blood group incompatibilities has increased in the etiology. Clinical presentation in patients with minor blood group incompatibility may vary from subclinical hemolysis findings to active hemolysis and hyperbilirubinemia requiring blood exchange. In this case study, we present a patient with hemolytic anemia due to anti-c antibody incompatibility.

Ecchymosis and Coldness in Peripheral Varicose Vein Patients: Observations From VEIN-TURKEY Study.

The purpose of this subgroup analysis is to investigate and analyze the venous leg symptoms including sense of coldness and sign of ecchymosis in patients with or without peripheral varicose veins (PVVs) from VEIN-TURKEY study population. A total of 600 patients, who were enrolled to VEIN-TURKEY study recently, were included in this subgroup analysis. Patients were examined clinically for the presence and severity of PVV and varicocele. Patients were asked to answer the VEINES-Sym questionnaire consisting of 10 parts and questions about ecchymosis and coldness in their legs. Frequency of symptoms present in the VEINES-Sym instrument, coldness (16.6%, 6.5%, P = .002, respectively), and ecchymosis (16.6%, 2.7%, P < .001, respectively) were significantly higher in patients with PVV compared to patients without PVV. Mean score of each symptom was significantly lower in PVV (+) patients including scores of ecchymosis and coldness. Total VEINES-Sym score was also correlated with the scores of ecchymosis (r = 0.18, P < .001) and coldness (r = 0.35, P < .001). Logistic regression analysis revealed that heavy legs, aching legs, night cramps, and ecchymosis are significantly and independently associated with PVV. In conclusion, sign of ecchymosis and coldness are significantly higher in patients with PVV compared to patients without PVV in a population recruited from the urology clinics. In clinical evaluation, presence or sign of ecchymosis and coldness in legs should be considered to be compatible with PVV in the absence of trauma, hematologic pathologies including antiplatelet treatment, and arterial stenosis or obstruction.

Association between atrial septal aneurysm and arrhythmias.

Objective. This study aimed to assess the association of atrial septal aneurysm (ASA) with cardiac arrhythmias by comparing patients with ASA with a control group with non-ASA, matched for age and gender. Methods. 641 patients with ASA who fulfilled the inclusion criteria were enrolled into the study. The control group consisted of 641 patients without ASA. Patients underwent physical, electrocardiographic and transthoracic echocardiographic examinations. Additional examinations such as transesophageal echocardiography, 24-h rhythm Holter monitoring, and electrophysiological study were performed when clinically needed. Results. There were no differences between the groups in respect to baseline demographic, clinical parameters and echocardiographic parameters except ischemic stroke and smoking status. Percentages of patients suffering from atrial premature complex (APC), ventricular premature complex (VPC), supraventricular tachycardia (SVT) and paroxysmal atrial fibrillation (AF) were higher in ASA patients compared to non-ASA patients. In addition, these parameters were independently associated with the presence of ASA in logistic regression analysis. Conclusions. Certain types of arrhythmias such as APC, VPC, SVT and paroxysmal AF have been shown to be independently associated with the presence of ASA.

Transcatheter Self-Expandable Aortic Valve (Portico) Implantation in a Patient with Previous Mitral Valve Replacement: A Case Report.

Transcatheter aortic valve implantation (TAVI) has shown favorable outcomes in patients with severe symptomatic aortic valve stenosis who are at high surgical risk or who are unsuitable candidates for open-heart surgery. However, concerns exist over treating patients who have undergone previous mitral valve surgery due to the potential interference between the mitral prosthetic valve or ring and the TAVI device. In this case report, we present a case in which a patient with symptomatic severe aortic stenosis and previous mechanical mitral valve replacement was successfully treated with TAVI using a Portico valve, which is under-researched.

The role of thiol levels in predicting contrast-induced nephropathy in patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention.

OBJECTIVE: Contrast-induced nephropathy (CIN) is a common complication of diagnostic or interventional procedures that may arise from administration of intravascular contrast media. Recent studies have reported the thiol-disulfide ratio as a novel oxidative stress marker. Therefore, we investigated the role of thiol levels in predicting CIN in patients with ST-segment elevation myocardial infarction (STEMI) who had undergone primary percutaneous coronary intervention (PCI). METHODS: A total of 302 patients were enrolled in the study. CIN was defined as an increase in serum creatinine concentration ≥0.5 mg/dL compared with the admission value or a >25% relative rise during the first 48-72 hours after the procedure. To evaluate the relationship between thiol levels and CIN, the patients were divided into a CIN group and a non-CIN group. RESULTS: CIN occurred in 44 (15%) patients. Native thiol (274.8±84.7 µmol/L vs. 220.8±97.1 µmol/L, p=0.001) and total thiol (305.4±89.7 µmol/L vs. 260.1±102.1 µmol/L, p=0.009) levels were higher in patients within the non-CIN group. Disulfide (15.8±6.6 µmol/L vs. 19.6±8.4 µmol/L, p=0.002) levels, and mean disulfide/total thiol ratios (8.4±3.7 vs. 5.9±3.1, p=0.001) were higher in patients with CIN (+) group. In univariate analysis, the initial native thiol, total thiol, disulfide levels, and disulfide/total thiol ratio were found to have prognostic significance in the development of CIN. In the multivariate regression analysis, only the disulfide/total thiol ratio (OR=1.190; 95% CI: 1.090-1.300; p=0.001) was significantly and independently associated with CIN. The cutoff value of the disulfide/total thiol ratio to predict CIN on admission in patients with STEMI who underwent primary PCI was 7, with a sensitivity of 68.2% and a specificity of 79.8%. CONCLUSION: Our results suggest that thiol/disulfide homeostasis could be a good biochemical risk marker for CIN in STEMI patients who underwent primary PCI.

Echocardiographic Findings in Patients with Atrial Septal Aneurysm: A Prospective Case-Control Study.

BACKGROUND: Atrial septal aneurysm (ASA) is a congenital deformity of the interatrial septum with a prevalence of 1-2% in the adult population. Although ASA has been supposed to be an incidental finding in echocardiographic examination, its structural and clinical associations have gained an increasing interest. AIM: To investigate and compare the clinical features and echocardiographic parameters between ASA patients and age- and gender-matched control group patients. METHODS: 410 patients with ASA were enrolled in the study, prospectively. After the exclusion of 33 patients, the remaining 377 patients comprised the study group. The control group consisted of 377 age- and gender-matched patients without ASA. RESULTS: Aortic valve regurgitation and mitral valve regurgitation were more often observed in patients with ASA, and percentages of patients with ascending aortic aneurysm (AAA), patent foramen ovale (PFO), and atrial septal defect (ASD) were higher in ASA patients compared to control group patients. Aortic root diameter was larger in ASA patients compared to control group patients (29.2 ± 3.9, 28.6 ± 3.1, p=0.05, respectively). Ascending aorta diameter was higher in ASA patients compared to patients without ASA (44 ± 0.3, 41.5 ± 0.2, p=0.02). Logistic regression analysis revealed that mitral valve regurgitation (OR: 2.05, 95% CI : 1.44-2.92, p < 0.001) and PFO (OR: 11.62, 95% CI : 2.64-51.02, p=0.001) were positively and independently associated with the presence of ASA. AAA tended to be statistically and independently associated with ASA (OR: 2.69, 95% CI : 0.97-7.47, p=0.05). CONCLUSIONS: We have demonstrated a higher incidence of mitral/aortic valvular regurgitations, AAA, PFO, and ASD in ASA patients compared to age- and gender-matched control group patients. In addition, we have shown that ASA is significantly and positively associated with mild mitral regurgitation and PFO.

Venous leg symptoms in patients with varicocele: A multicenter assessment study (VEIN-TURKEY study).

OBJECTIVE: The aim of this study is to evaluate chronic venous disease symptoms by using the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms (VEINES-QoL/Sym) questionnaire in varicocele patients. MATERIAL AND METHODS: The study was designed as a prospective, case controlled study and conducted in four hospitals from Turkey. A total of 600 patients who admitted to urology outpatient clinic were enrolled to the study. After the exclusion of 44 patients who do not match the inclusion criteria, the remaining 556 patients were examined for the presence and grade of varicocele and subsequently examined clinically for the presence of chronic venous disease findings. Finally, patients were asked to answer the VEINES-Sym questionnaire consisting of 10 items. All patients' demographic parameters, cardiovascular risk factors, other co-morbid diseases and drug usage were noted. RESULTS: Patients were classified into two groups: varicocele (+) group ( n = 269) and varicocele (-) group ( n = 287). VEINES-Sym scores of varicocele patients were lower compared to patients without varicocele (41.41 ± 5.21, 43.19 ± 3.22, respectively, p < 0.001). Grades of varicocele significantly but inversely correlated with VEINES-Sym score ( r = 0, -206, p = 0.001). Logistic regression analysis revealed that presence of varicocele irrespective of grading significantly and independently associated with the presence of aching (odds ratio: 2.054, 95% confidence interval: 1.265-3.338, p = 0.004) and throbbing (odds ratio: 2.586, 95% confidence interval: 1.353-4.943, p = 0.004). CONCLUSION: Varicocele patients have lower VEINES-Sym scores compared to patients without varicocele and this finding is inversely correlated with the degree of the varicocele. This association supports the hypothesis that there may be a systemic vessel wall abnormality in venous disease patients. Patients with symptoms related to vascular dilatation in any territory may deserve to be assessed systematically with the support of further clinical studies.

Can hemodialysis change QRS axis in patients without cardiovascular disease?

OBJECTIVE: Due to rapid changes in volume and electrolyte concentration during hemodialysis (HD), some electrocardiographic (ECG) changes or arrhythmias can be seen. The aim of this study was to assess ECG QRS axis changes and other ECG parameters after HD in patients with end-stage renal disease (ESRD). METHODS: A total of 46 patients (65% male, mean age 52±15 years) with a sinus rhythm and without cardiovascular disease who were undergoing chronic HD treatment were included to the study. Blood samples, 12-lead electrocardiograms, and echocardiograms were recorded immediately before and at the end of an HD session. The QRS axis and other electrocardiographic, echocardiographic, electrolyte parameter, and volume changes were analyzed. RESULTS: The serum urea, creatinine, potassium, and B-type natriuretic peptide concentrations significantly decreased after HD, and the serum calcium levels significantly increased after HD. Body weight significantly decreased after HD. There was no significant difference in the QRS duration, PR interval, P-wave axis, QRS axis, or QT and QTc interval following HD. Based on a comparison of variables according to the any QRS axis change after HD treatment, there was no significant difference in biochemical values, HD time, ultrafiltration volume, left ventricular ejection fraction, or other echocardiographic findings. CONCLUSION: ESRD and HD are complex and dynamic processes, and the change in the QRS axis is rarely emphasized in these patients. In our study, there was no significant change in the QRS axis with HD in patients without cardiovascular disease.

Ecchymosis: A novel sign in patients with varicose veins.

BACKGROUND: In the absence of trauma, hematologic disease and anti-platelet use, no attention has been paid to elucidate the mechanism of ecchymosis. It has taken our attention that ecchymosis on lower limb might be a sign of varicose vein. Accordingly, we aimed to analyze and describe the frequency of leg symptoms and presence of ecchymosis in patients with varicose vein. MATERIALS AND METHODS: Four hundred and ninety four patients who had been diagnosed as having varicose vein or chronic venous insufficiency either by clinical examination or Doppler ultrasonography were included in the study. Leg symptoms were defined as pain, itching, muscle cramps, throbbing, and swelling. Ulcers, pigmentations and ecchymosis were recorded as signs of varicose vein. Ecchymosis was defined as a hemorrhagic lesions, larger than >3 mm on the skin of lower extremities, forming a flat, rounded or irregular, blue or purplish patch. RESULTS: Leg pain was the most common symptom in our study population. Ecchymosis was observed in 24 patients (5%). Logistic regression analysis showed that ecchymosis was significantly and positively associated with muscle cramps (Odds ratio: 5.82, p = 0.001) and female gender (Odds ratio: 5.17 p = 0,019 but negatively associated with age (Odds ratio: 0.94, p = 0.004). CONCLUSION: We have documented for the first time that the frequency of ecchymosis and its association with muscle cramps in a relatively large patient population with peripheral varicose vein or chronic venous insufficiency. Ecchymosis on lower limbs should be considered as a novel sign of varicose vein.

Combination of change in hematological parameters with exercise stress test to predict coronary artery disease.

OBJECTIVE: Treadmill exercise stress testing for identifying patients with a higher likelihood of coronary artery disease (CAD) before elective coronary angiography is recommended in the current guidelines. In this study, we aimed to evaluate the changes in the hematological parameters before and after exercise stress test in relation with the presence of CAD. METHODS: A total of 113 patients with chest pain who underwent treadmill exercise testing and coronary angiography were included in this study. RESULTS: Neutrophil count (4.38±0.99 vs 5.19±0.93, P<.001), and neutrophil to lymphocyte ratio (NLR) (2.04±0.63 vs 2.41±0.78, P<.001) were significantly elevated after treadmill exercise test in all the patients. Increase in the NLR after exercise test was significantly higher in patients with positive exercise test (n=68) than negative exercise test (n=45) (0.49±0.58 vs 0.19±0.44, P=.016). The sensitivity and specificity of treadmill exercise testing according to coronary angiography was 79% and 64%, respectively. A cut-off point of 0.2 for the change in the NLR in addition to positive treadmill exercise testing had 91% sensitivity and 92% specificity in predicting significant coronary artery stenosis (AUC:0.913, 95% CI: 0.805-1.000, P<.001). CONCLUSIONS: Neutrophil to lymphocyte ratio is an important inflammatory marker that can contribute to treadmill ECG testing in predicting CAD.

A Novel Risk Scoring System to Predict Cardiovascular Death in Patients With Acute Myocardial Infarction: CHA2DS2-VASc-CF Score.

The present study aimed to determine the long-term prognostic validity of the CHA2DS2-VASc score in patients with acute myocardial infarction (AMI). In addition, we formulated a novel scoring system, the CHA2DS2-VASc-CF (which includes cigarette smoking and a family history of coronary artery disease as risk factors). This study included 4373 consecutive patients with AMI who presented to the emergency department of our hospital and underwent cardiac catheterization procedures between December 2009 and September 2016. Among these patients, 1427 were diagnosed with ST elevation myocardial infarction (STEMI) and 2946 were diagnosed with non-STEMI. The study included 4373 patients. The study population was divided into 2 groups according to the occurrence of cardiovascular death during the follow-up period. Multivariate logistic regression analysis showed that the CHA2DS2-VASc-CF score, CHA2DS2-VASc score, major adverse cardiac events, current cigarette smoking, older age, hypertension, and family history of coronary artery disease were significantly higher, and that the left ventricular ejection fraction and glomerular filtration rate were significantly lower in the cardiovascular death (+) group. Using a cutoff score of >3 for the CHA2DS2-VASc-CF score, long-term cardiovascular death was predicted with a sensitivity of 78.4% and specificity of 76.4%. The CHA2DS2-VASc-CF score is suitable for use in all patients with AMI, regardless of the type of treatment, presence of atrial fibrillation, and type of AMI. This risk score, which is easy to calculate, provides important prognostic data. In the future, we think that interventional cardiologists will be able to use this novel scoring system to identify patients with a high risk of long-term cardiovascular death.

Homocysteine, visceral adiposity-related novel cardiometabolic risk factors, and exaggerated blood pressure response to the exercise treadmill test.

OBJECTIVE: Exaggerated blood pressure response to exercise is a risk factor for the development of future hypertension. In this study, we aimed to investigate the association between homocysteine, epicardial fat thickness, nonalcoholic hepatic steatosis, and exaggerated blood pressure response to exercise. PARTICIPANTS AND METHODS: We included 44 normotensive and 40 patients with exaggerated blood pressure response to exercise who have normal resting blood pressure and without a previous diagnosis of hypertension. All patients underwent treadmill exercise test and clinical, ultrasonographic, and echocardiographic evaluation. Exaggerated blood pressure response to exercise is defined as peak exercise systolic blood pressure of at least 210 mmHg in men and at least 190 mmHg in women. Homocysteine and other biochemical parameters were determined with standardized automated laboratory tests. RESULTS: Mean age of all participants is 47.9±8.5 years, and 36 of 84 participants were female. The frequency of diabetes mellitus in both groups was similar (P=0.250). Homeostasis model assessment index-insulin resistance had a statistically insignificant trend to be higher in a patient with exercise hypertension (P=0.058). The nonalcoholic fatty liver was more frequent in patients with exercise hypertension (13.6 vs. 47.5%, P=0.002). Epicardial fat thickness was increased in patients with exercise hypertension (5.5±1.5 vs. 7.3±1.1 mm; P=0.001). However, homocysteine levels did not significantly differ between normotensive and exercise hypertensive patients [12.3 µmol/l (5.7-16.9 µmol/l) vs. 13 µmol/l (5.9-28.3 µmol/l); P=0.883]. CONCLUSION: In our study, homocysteine levels were not associated with exaggerated blood pressure response to exercise; however, fatty liver and epicardial fat thickness as visceral adiposity-related cardiometabolic risk factors were significantly related with exaggerated blood pressure response to exercise in patients without a previous diagnosis of hypertension.

Evaluation of Whole Blood Viscosity in Patients with Aortic Sclerosis.

Background: Blood viscosity and aortic sclerosis (AS) are strong predictors of cardiovascular events. The effects of blood viscosity on AS have not been studied adequately. We aimed to investigate the potential connection between whole blood viscosity (WBV) and AS. Methods: AS was detected by transthoracic echocardiography. The estimation of WBV was carried out at both high shear rate (HSR) (208/s) and low shear rate (LSR) (0.5/s) by previously validated formulae using hematocrit (HcT) and total protein (TP) in g/L. WBV at HSR (208/s) is: (0.12 × HcT) + 0.17 (TP - 2.07) and WBV at LSR (0.5/s) is: (1.89 × HcT) + 3.76 (TP - 78.42). Comparisons of WBV at both HSR and LSR were made between patients with and without AS. Results: We included 94 patients with AS (male = 30.9%, mean age = 67.5 y) and 97 control subjects without AS (male =26.6%, mean age = 69.1 y). Almost all of the clinical, echocardiographic, and biochemical characteristics were similar, but TP values were significantly higher in the AS group than in the control group (72.9 ± 5 g/L vs. 75.8 ± 6.1 g/L; p value < 0.001). Hemoglobin and HcT levels were similar (p value = 0.604 and p value = 0.431, respectively). In the AS group, WBV at LSR and HSR was higher than that in the control group (p value = 0.001 for both LSR and HSR). In multiple stepwise logistic regression analysis, WBV was an independent predictor of AS (p value < 0.001). Conclusion: We found higher WBV in patients with AS than in patients without AS at both LSR (0.5/s) and HSR (208/s). WBV at both LSR and HSR was independently associated with AS.

The relationship between fragmented QRS and functional significance of coronary lesions.

BACKGROUND: Recently fragmented QRS (fQRS) on electrocardiography (ECG) has been introduced as a predictor of myocardial scarring and myocardial ischemia in coronary artery disease (CAD). OBJECTIVE: The aim of this study was to investigate the relationship between fQRS and fractional flow reserve (FFR) results in patients with the intermediate degree of coronary artery stenosis. METHODS: A total of 301 consecutive patients who underwent coronary angiography (CAG) and FFR measurement for intermediate coronary artery stenosis were included in the study. The study patients were divided into two groups: the low FFR group (FFR value of ≤0.80) and normal FFR (FFR value of >0.80) group. Both groups were compared in terms of the presence of fQRS. RESULTS: Of 301 patients, fQRS was detected in 128 (42.5%) and low FFR was detected in 115 (38.2%). In the low FFR group, fQRS was significantly higher (P<0.001). Multivariate analysis showed that fQRS was an independent predictor of myocardial ischemia in patients with intermediate coronary stenosis (OR=7.202, CI 95%, 4.195-12.367; p<0.001). The presence of fQRS had 70% sensitivity and 74% specificity for the prediction of FFR≤0.80. CONCLUSION: In clinical practice, the presence of fQRS on ECG is associated with myocardial ischemia in patients with intermediate coronary stenosis.
