A mix of aminophylline and heparin plus nitroglycerin can reduce bradycardia during rotational atherectomy on the right coronary artery and dominant circumflex artery.

BACKGROUND: Rotational atherectomy (RA) may cause bradyarrhythmias and transitory atrioventricular block when performed in the right coronary artery (RCA) or a dominant circumflex (CX) coronary artery. However, there are no studies of a solution that can prevent coronary flow deterioration and bradycardia complications that may occur during RA. We aimed to create an alternative rota-flush solution to minimize the risk of bradycardia and complete atrioventricular block (AVB) that can occur during RA. MATERIALS AND METHODS: The study comprised 60 patients who were randomly divided into two groups: 30 received rotaphylline (= 240 mg aminophylline, 10,000 U unfractionated heparin, and 2000 mcg nitroglycerin to 1000 mL saline), and 30 received the traditional rota-flush (= 10,000 U unfractionated heparin, 2000 mcg nitroglycerin, and 1000 mL saline). The incidence of bradycardia or high-grade AVB (HAVB) during RA, coronary slow-flow phenomenon or no-reflow phenomenon, and coronary spasm were the primary endpoints of the study. Procedure success and RA-related procedural complications were secondary endpoints. RESULTS: The use of rotaphylline was an independent predictor of bradycardia and HAVB after accounting for all other factors (OR: 0.47, 95% CI: 0.24-0.79, p < 0.001). Lesion length (OR: 2.17, 95% CI: 1.24-3.04, p < 0.001), burr-to-artery ratio (OR: 0.59, 95% CI: 0.39-1.68, p < 0.001), and total run duration (OR: 0.79, 95% CI: 0.35-1.43, p < 0.001) were additional independent predictors. CONCLUSION: Bradycardia and the development of HAVB may be avoided by rotaphylline intracoronary infusion during RA applied to the RCA and dominant CX lesions. Multicenter studies including sizable patient populations should be conducted to validate the present findings.

The role of baseline and post-treatment frontal QRS-T angle for detecting arterial blood pressure control.

Objectives: In this study, we aimed to investigate the value of the frontal QRS-T angle (f(QRS-T)) in determining blood pressure control among newly diagnosed hypertensive patients with no left ventricular hypertrophy.Methods: Fifty patients with newly diagnosed hypertension were included in this single-center study. The patients were examined with 12-lead ECGs and 24-hour ambulatory blood pressure monitoring (24 h-ABPM) before and 1 month after antihypertensive treatment.Results: Baseline and post-treatment f(QRS-T) angle values were observed to be similar (38.0 [0.0-174.0] and 37.0 [1.0-139.0], respectively; p = .827). The values of QT minimum (p = .006), QTc mean (p = .030), Tp-e (p = .027), and JTc (p = .010) significantly decreased after control of blood pressure.Conclusions: The f(QRS-T) angle, which can be easily calculated on the ECG, is not a useful tool to determine hypertension control at early stage in newly diagnosed hypertensive patients.

Interpretation of arrhythmogenic effects of COVID-19 disease through ECG.

OBJECTIVE: We aimed to detect the malignant arrhythmic potential of COVID-19 with surface electrocardiographic (ECG) markers. MATERIAL AND METHOD: Of the ECG parameters PR, QT, QTc, QTd, TPe, and Tpe/QTc were measured in 51 COVID-19 patients and 40 in control subjects. RESULTS: Compared to control group mean QTc (410.8 ± 24.3 msec vs. 394.6 ± 20.3 msec, p < .001) and Tpe/QTc (0.19 ± 0.02 vs. 0.18 ± 0.04, p = .036) and median QTd (47.52 vs. 46.5) values were significantly higher in COVID-19 patients. Troponin levels were significantly correlated with heart rate (r = 0.387, p = .006) but not with ECG parameters. CONCLUSION: Several ventricular arrhythmia surface ECG predictors including QTc, QTd, and Tpe/QTc are increased in COVID-19 patients. Since medications used in COVID-19 patients have the potential to affect these parameters, giving importance to these ECG markers may have a significant contribution in decreasing disease-related arrhythmias.

Differential value of eosinophil count in acute coronary syndrome among elderly patients.

We aimed to search eosinophil (EOS) counts in elderly acute coronary syndrome (ACS) subjects and to investigate its value for discrimation between unstable angina pectoris (UAP) and myocardial infarction (MI) [non-ST elevation MI (NSTEMI) or ST elevation MI (STEMI)]. The patients were divided into three groups regarding the diagnosis: patients with UAP (63), with NSTEMI (154), and with STEMI (73). General characteristics such as gender, age, systolic and diastolic blood pressure were obtained from patients' files. Complete blood count and biochemical parameters were measured before coronary angiography. EOS was found significantly higher in UAP (0.134 (0.002-0.746) u/mm3) compared to NSTEMI (0.085(0.001-0.601) u/mm3) and STEMI (0.020(0.001-0.479) u/mm3) groups. Kruskal-Wallis test with Bonferroni-corrected Mann-Whitney U-test revealed that EOS count was significantly different between UAP and NSTEMI (p < .001), UAP and STEMI (p < .001) and NSTEMI and STEMI (p < .001) groups. A receiver operating curve (ROC) analysis revealed that a cut-off >0.083 u/mm3 EOS value had a sensitivity of 79% and specificity of 57% for determination of ACS as UAP (AUC = 0.686, 95% CI, 0.617-0.755). In the present study, we detected an inverse relationship between the number of blood eosinophil count and the severity of ACS subgroups in elderly patients with higher counts in UAP than MI groups.

The Left Distal transradial access site could give a safe alternate site for transradial coronary intervention (The Litaunent Study).

Transradial Access (TRA) is the suggested method when performing coronary procedures. TRA has several advantages over the transfemoral approach, but also some restrictions. The present study compared the efficacy and safety of the traditional proximal transradial approach (pTRA) with a newer technique known as the distal transradial approach (dTRA) for performing a coronary angiography (CAG) and percutaneous coronary intervention (PCI). Patients (n = 700) were placed into one of two categories (dTRA or pTRA) based on a random technique. The primary endpoint was RAO at follow-up. The secondary endpoints included the time required for sheath insertion, the rate of successful sheath insertion, rate of successful completion of CAG and PCI, total procedure time, total fluoroscopy time, total radiation dose, total contrast volume used, pain perception (visual analog scale 0-10), and hemostasis duration. dTRA patients had more skin punctures, failed punctures, failed wiring, overlap of access sites, sheath insertion time, and pain evaluation scale, while the pTRA group had more hemostasis time and first-time cannulation. RAO and pseudoaneurysm (PseA) were lower in the dTRA group. In this randomized study, dTRA had lower RAO and PseA than pTRA. However, multicenter, larger-patient trials are needed to provide definitive evidence.

Hypertension and Occupational Health: A General Overview and Expert Consensus Suggestions.

Hypertension is a common public health issue, and its incidene increases parallel to age. It is inevitable that certain occupational conditions may pose risks for high blood pressure or cause difficulties in managing blood pressure. Working under specific circumstances may compromise the safety of individuals with hypertension and potentially others. Therefore, it is crucial to implement activities that enhance awareness of hypertension, to ensure regular periodic examinations, and to establish necessary precautions in the workplace for the health of employees and the public. Given the limited resources offering guidance on hypertension in the context of occupational health, the authors of this paper, who hail from different disciplines, have prepared a set of consensus-based suggestions.

A novel echocardiographic method for the detection of subclinical atherosclerosis in newly diagnosed, untreated type 2 diabetes.

BACKGROUND: Diabetes accelerates the natural process of atherosclerosis and is a predictor for progression of atherosclerotic lesions. To improve clinical outcomes, noninvasive imaging modalities have been proposed to measure and monitor atherosclerosis. Recently, it has been shown that the color M-mode-derived propagation velocity of the descending thoracic aorta (aortic velocity propagation [AVP]) was associated with coronary and carotid atherosclerosis. METHODS: Carotid intima-media thickness (CIMT) and AVP were measured in 72 patients with newly diagnosed type 2 diabetes and 44 healthy people. Individuals who had previously used oral hypoglycemic agents or insulin treatment or had a history of hyperlipidemia, cigarette smoking, hypertension, and cardiovascular disease were excluded from this study. RESULTS: Compared with control group, patients with type 2 diabetes had significantly lower AVP (39.9 ± 6.5 vs. 58.4 ± 6.7 cm/sec, P < 0.001) and higher CIMT (1.1 ± 0.1 vs. 0.95 ± 0.12 mm, P < 0.001) measurements. There were significant correlations between AVP and CIMT (r = -0.835, P < 0.001), AVP and fasting plasma glucose (r = -0.796, P < 0.001)), AVP and HbA1 c (r = -0918 P < 0.001). CONCLUSIONS: Diabetes mellitus may be associated with subclinical atherosclerosis assessed by measurement of AVP and CIMT. These simple methods might improve patient selection for primary prevention atherosclerotic progression.

Increased risk of atrial and ventricular arrhythmia in long-lasting psoriasis patients.

BACKGROUND: Several reports have demonstrated an association between psoriasis and cardiovascular diseases. P wave dispersion (PWD) is the most important electrocardiographic (ECG) markers used to evaluate the risk of atrial arrhythmias. QT dispersion (QTD) can be used to assess homogeneity of cardiac repolarization and may be a risk for ventricular arrhythmias. AIM: To search PWD and QTD in patients with psoriasis. METHODS: Ninety-four outpatient psoriasis patients and 51 healthy people were evaluated by physical examination, 12-lead ECG, and transthoracic echocardiography. Severity of the psoriasis was evaluated by psoriasis area and severity index (PASI). RESULTS: Mean disease duration was 129.4 ± 83.9 (range, 3-360) months and PASI ranged from 0 to 34.0 (mean ± SD; 7.6 ± 6.7). Compared to control group, psoriatic patients had significantly shorter Pmax and Pmin durations, longer QTcmax, and greater PWD and QTcD. Transmitral deceleration time (DT) and isovolumetric relaxation time (IVRT) were significantly longer among psoriasis patients. QTcD and PWD were significantly correlated with disease duration (r = 0.693, P < 0.001, and r = 0.368, P = 0.003, resp.). CONCLUSIONS: In this study, we found that both PWD and QTcD are increased in psoriasis patients compared to healthy subjects. In addition, they had longer DT and IVRT.

Clinical and echocardiographic follow-up in pregnant patients with valvular heart disease.

OBJECTIVES: Pregnancy associated cardiovascular changes may result in a significant hemodynamic burden and can lead to morbidity and even mortality in women with cardiac disease. The present study aimed to evaluate clinical and echocardiographic follow-up in pregnant patients with valvular heart disease (VHD). STUDY DESIGN: The medical records of pregnant patients diagnosed with VHD from January 2004 to January 2011 were screened. Demographic characteristics including history of cardiac intervention performed during pregnancy, pulmonary edema, and maternal and fetal mortality, and cesarean section (C/S) history were collected from the hospital database and clinical records of the cardiology and obstetrics departments. The echocardiographic examination was carried out at presentation, 3rd trimester, and 1 month after delivery. The outcomes evaluated were cardiac intervention, pulmonary edema, and both fetal and maternal mortality during pregnancy and C/S. RESULTS: We evaluated the outcomes of 884 pregnant patients with VHD. Adverse clinical outcomes including death, pulmonary edema, and valvular interventions were frequent among patients with severe VHD, whereas no adverse clinical outcome was observed in patients with mild-moderate VHD (n=49, 5.5% vs. n=0, 0%, p<0.001). In patients with severe VHD, clinical outcomes were frequent among patients with valve stenosis, but lower among patients with regurgitation [death 4 (0.45%) vs. 0 (0%); pulmonary edema (15 (1.7%) vs. 13 (1.5%); valvular intervention 11 (1.2%) vs. 6 (0.7%); respectively). CONCLUSION: Valvular heart disease is associated with fetal/maternal morbidity and mortality. Pregnant with severe VHD constitute a high-risk group in which life-threatening complications are likely to occur in the course of pregnancy.

[Percutaneous closure of secundum atrial septal defects in pediatric and adult patients: short- and mid-term follow-up results]. / Eriskin ve çocuklardaki sekundum tip atriyal septal defektlerin perkütan yaklasim ile kapatilmasi: Kisa-orta dönem izlem sonuçlarimiz.

OBJECTIVES: We aimed to evaluate the short- and mid-term results of patients with atrial septal defect (ASD) who were treated with percutaneous closure. STUDY DESIGN: Seventy-nine patients with secundum ASD (54 female and 25 male; mean age 26.2±17.2; range 3 to 71] years) were included in this study. Patients were evaluated by transthoracic (TTE) and/or transesophageal echocardiography (TEE). Amplatzer septal occluder (ASO) was used in all patients. In 76 patients, the procedure was performed under local anesthesia with TTE, while in the other 3 patients, it was performed with general anesthesia with TEE. Patients were followed up at the 1st, 3rd, 6th and 12th months and annually thereafter. Mean follow-up time was 13.6±6.6 months. RESULTS: Mean diameter of ASDs was 18.2±7.5 mm and 20.7±8.04 mm during balloon dilatation, and mean diameter of implanted devices was 22.7±8.5 mm. Procedural time was 40.2±12.6 minutes and fluoroscopy time was 10.9±4.1 minutes. The procedure was successfully performed in all patients (100%). One patient with cardiac tamponade died seven days after cardiac surgery. In two patients, the implanted devices embolized to the pulmonary circulation. Residual flow was found in three patients immediately after the procedure, without residual shunts one month after closure. Mild pericardial effusion in one patient and significant residual shunt due to device malposition in another were discovered during the follow-up at 1 and 6 months, respectively, after the procedure. CONCLUSION: Our findings showed that percutaneous closure of ASDs is successful in most patients with a low complication rate, and demonstrated that residual shunts do not develop in the majority of patients in the short- and mid-term.

Evaluation of Endothelial Dysfunction in COVID-19 With Flow-Mediated Dilatation. / Avaliação da Disfunção Endotelial em Casos de COVID-19 com Dilatação Fluxo-Mediada.

BACKGROUND: Inflammation is known to play a crucial role in many diseases, including COVID-19. OBJECTIVE: Using flow-mediated dilatation (FMD), we aimed to assess the effects of inflammation on endothelial function in COVID-19 patients. METHODS: This study was conducted with a total of 161 subjects, of whom 80 were diagnosed with COVID-19 within the last six months (comprising 48 women and 32 men with a mean age of 32.10 ± 5.87 years) and 81 were healthy controls (comprising 45 women and 36 men with a mean age of 30.51 ± 7.33 years). We analyzed the findings of transthoracic echocardiography and FMD in all subjects. All results were considered statistically significant at the level of p < 0.05. RESULTS: The echocardiography and FMD of the COVID-19 group were performed 35 days (range: 25-178) after diagnosis. There was no statistically significant difference in echocardiographic parameters. Differently, FMD (%) was significantly higher in the control group (9.52 ± 5.98 vs. 12.01 ± 6.18, p=0.01). In multivariate analysis with the forward stepwise model, FMD was significantly different in the control group compared to the COVID-19 group (1.086 (1.026 - 1.149), p=0.04). A Spearman's correlation test indicated that FMD (r=0.27, p=0.006) had a weak positive correlation with the presence of COVID-19. CONCLUSION: Our findings point to COVID-19-induced endothelial dysfunction, as assessed by FMD, in the early recovery phase.

FUNDAMENTO: Sabe-se que a inflamação desempenha um papel crucial em muitas doenças, incluindo a COVID-19. OBJETIVO: Utilizando a dilatação fluxo-mediada (DFM), objetivou-se avaliar os efeitos da inflamação na função endotelial de pacientes com COVID-19. MÉTODOS: Este estudo foi realizado com um total de 161 indivíduos, dos quais 80 foram diagnosticados com COVID-19 nos últimos seis meses (48 mulheres e 32 homens com idade média de 32,10±5,87 anos) e 81 eram controles saudáveis (45 mulheres e 36 homens com idade média de 30,51±7,33 anos). Os achados do ecocardiograma transtorácico e da DFM foram analisados em todos os indivíduos. Resultados com p<0,05 foram considerados estatisticamente significantes. RESULTADOS: O ecocardiograma e a DFM do grupo COVID-19 foram realizados 35 dias (intervalo: 25­178) após o diagnóstico. Não houve diferença estatisticamente significativa nos parâmetros ecocardiográficos. Em contraste, a DFM (%) foi significativamente maior no grupo controle (9,52±5,98 versus 12,01±6,18; p=0,01). Na análise multivariada com o modelo stepwise progressivo, a DFM foi significativamente diferente no grupo controle em relação ao grupo COVID-19 (1,086 (1,026­1,149), p=0,04). O teste de correlação de Spearman indicou que a DFM (r=0,27; p=0,006) apresentou correlação positiva fraca com a presença de COVID-19. CONCLUSÃO: Os achados deste estudo apontam para disfunção endotelial induzida por COVID-19, avaliada por DFM, na fase inicial de recuperação.

Poorly controlled hypertension is associated with elevated serum uric acid to HDL-cholesterol ratio: a cross-sectional cohort study.

OBJECTIVES: The diagnosis and follow-up of hypertension (HT) depend on the blood pressure measurements, which can be affected by several factors. In the present work, we aimed to explore the role of uric acid/HDL-cholesterol ratio (UHR) in HT and whether/or not it was associated with poor blood pressure control. METHODS: In this retrospective cross-sectional cohort study, all the participants treated for hypertension and then followed up in the internal medicine clinics of our institution were enrolled. Hypertensive patients were grouped as either poorly or well-controlled hypertension groups, according to the suggestions of Joint National Committee VIII criteria and healthy volunteers were enrolled as control group. UHR of the study groups was compared. RESULTS: Our study cohort consisted of 535 subjects; 258 in the well-controlled HT group, 186 in the poorly controlled HT group, and 91 in the control group. Median UHR levels of the poorly controlled HT group (13 (4-43) %) were significantly higher than well-controlled HT group 11 (4-22) %) and control group (8 (4-19) %) (p < 0.001). UHR was correlated with systolic (r = 0.33, p < 0.001) and diastolic (r = 0.28, p < 0.001) BP. UHR level greater than 11% has 70% sensitivity and 60% specificity in predicting poor BP control (AUC: 0.73, p < 0.001, 95%CI: 0.68-0.77). UHR was an independent risk factor for poor BP control in HT subjects and a unit elevation in UHR increased the risk of poorer BP control by 7.3 times (p < 0.001, 95%CI: 3.9-13.63). CONCLUSION: Assessment of UHR may be useful in HT patients since elevated UHR levels could be associated with poor blood pressure control in this population.

Trace elements, heavy metals and vitamin levels in patients with coronary artery disease.

AIM: In the present study, we aimed to assess serum concentrations of zinc (Zn), copper (Cu), iron (Fe), cadmium (Cd), lead (Pb), manganese (Mn), vitamins A (retinol), D (cholecalciferol) and E (α-tocopherol) in patients with coronary artery disease (CAD) and to compare with healthy controls. METHODS: A total of 30 CAD patients and 20 healthy subjects were included in this study. Atomic absorption spectrophotometry (UNICAM-929) was used to measure heavy metal and trace element concentrations. Serum α-tocopherol, retinol and cholecalciferol were measured simultaneously by high performance liquid chromatography (HPLC). RESULTS: Demographic and baseline clinical characteristics were not statistically different between the groups. Serum concentrations of retinol (0.3521 ± 0.1319 vs. 0.4313 ± 0.0465 mmol/I, p=0.013), tocopherol (3.8630 ± 1.3117 vs. 6.9124 ± 1.0577 mmol/I, p<0.001), cholecalciferol (0.0209 ± 0.0089 vs. 0.0304±0.0059 mmol/I, p<0.001) and Fe (0.5664 ± 0.2360 vs. 1.0689 ± 0,4452 µg/dI, p<0.001) were significantly lower in CAD patients. In addition, while not statistically significant serum Cu (1.0164 ± 0.2672 vs. 1.1934 ± 0.4164 µg/dI, p=0.073) concentrations were tended to be lower in patients with CAD, whereas serum lead (0.1449 ± 0.0886 vs. 0.1019 ± 0.0644 µg/dI, p=0.069) concentrations tended to be higher. CONCLUSIONS: Serum level of trace elements and vitamins may be changed in patients with CAD. In this relatively small study we found that serum levels of retinol, tocopherol, cholecalciferol, iron and copper may be lower whereas serum lead concentrations may be increased in patients with CAD.

The effects of perindopril on QT duration and dispersion in patients with coronary slow flow.

Coronary slow flow (CSF) is characterized by delayed opacification of coronary arteries in the absence epicardial occlusive disease. QT duration and dispersion have been reported to be longer in patients with CSF. ACE inhibitors may improve CSF through positive effects on endothelial function. The study included 32 patients having CSF and 25 subjects having normal coronary arteries in coronary angiography. The patients were evaluated with 12-leads electrocardiography and echocardiography before and 3 months after treatment with perindopril. Compared to the control group, maximum corrected QT duration (QTcmax) (432.0 ± 28.9 vs. 407.0 ± 39.1 ms, p = 0.008) and QT dispersion (QTcD) (64.0 ± 16.5 vs. 37.3 ± 12.1 ms, p < 0.001), mitral inflow deceleration time (DT) (251.3 ± 49.4 vs. 218.8 ± 44.5 ms, p = 0.013), and isovolumetric relaxation time (IVRT) (115.8 ± 18.4 vs. 107.2 ± 22.9 ms, p < 0.001) were significantly longer and E/A ratio 0.85 ± 0.2 vs. 1.1 ± 0.3, p = 0.004) was lower in patients with CSF. QTcmax (to 407.0 ± 28.0 ms, p = 0.001), QTcD (to 44.5 ± 11.4 ms, p < 0.001), DT (to 221.6 ± 37.7 ms, p < 0.001) and IVRT (to 103.8 ± 16.1 ms, p < 0.001) were significantly decreased and E/A ratio (to 0.98 ± 0.3, p < 0.001) was significantly increased after treatment with perindopril. Coronary slow may be associated with prolonged QT interval and increased QT dispersion and impaired diastolic filling. Perindopril may be helpful in restoration of these findings.

Dating thrombus organization with eosinophil counts in deep venous thrombosis.

OBJECTIVE: It is known that eosinophils (EOS) are essential for thrombus formation. Studies have demonstrated the association of EOS with coronary artery disease, stent thrombosis, coronary collateral development, and vasospastic angina. However, there is little data about the association of hemogram parameters, especially EOS counts, with deep venous thrombosis (DVT) subgroups. METHODS: The present study comprised 243 patients diagnosed with DVT (of whom 86 were acute, 72 were indeterminate, and 85 were chronic) and 75 control patients. Medical records of all the patients were reviewed, and relevant data were collected retrospectively. The baseline characteristics, as well as hemogram and biochemistry parameters, were recorded. RESULTS: The patients with DVT had significantly lower median EOS count yet higher median neutrophil to lymphocyte ratio (NLR) than those of control patients (P < .001). Similarly, acute DVT patients had lower EOS count yet higher NLR values compared with those of indeterminate and chronic DVT patients. However, EOS count was not significantly different between chronic DVT and control groups. While NLR ratio was significantly correlated with acute DVT (r = 0.34; P < .001), Spearman's correlation test revealed that EOS count was inversely correlated with the presence of acute DVT (r = -0.52; P < .001). CONCLUSIONS: Low EOS count may lead the physician to a higher probability of acute DVT rather than indeterminate and chronic DVT.

P-wave Duration and Dispersion in Lone Obesity.

OBJECTIVE: To assess P-wave duration and dispersion (PD) in morbidly obese young subjects who do not have co-associated atrial fibrillation (AF) risk factors, such as hypertension, diabetes, atrial enlargement and diastolic dysfunction. STUDY DESIGN: An observational cross-sectional study. PLACE AND DURATION OF STUDY: Bolu Abant Izzet Baysal University Medical Faculty, Turkey; and the study was conducted between October 2017 and June 2018. METHODOLOGY: P-wave duration and dispersions were determined on 12-lead surface ECG in 47 morbidly obese and 44 healthy weight subjects, aged between 21-40 years. Above mentioned risk factors were studied. The correlation between BMI, PD and Pmax were investigated by Pearson correlation analysis.  Results: Average body mass index (BMI) of obese and control groups were 42.3 (8.5) vs. 19.5 (1.5) (P <0.001). Maximum P-wave duration [(Pmax), 105.3±9.8 vs. 95.6±8.5, p<0.001] and PD [27.6 (7.6) vs. 12.2(8.3), p<0.001] were statistically significantly prolonged in obese patients when compared to the normal weight group. BMI correlation with Pmax and PD (r=0.485; p<0.001 and r=0.620; p<0.001, respectively) were significant. CONCLUSION:   Pmax and PD, which are potential electrocardiographic AF predictors, may increase in lone obese patients having no comorbidities. Key Words:  Electrocardiography, Arrhythmia, P-wave duration, P-wave dispersion, Severe obesity.

Prediction of More Severe MEFV Gene Mutations in Childhood.

AIM: This study aimed to present the demographic, clinical, and laboratory features of children clinically diagnosed with familial Mediterranean fever (FMF) and to predict more severe mutations by evaluating those findings. METHODS: We enrolled cases diagnosed with FMF with a defined variation in at least one allele. The medical charts of the patients were reviewed retrospectively. The patients were grouped as homozygous, compound heterozygous, and simple heterozygous cases, with and without M694V mutation. We compared the data between the subgroups using logistic regression analysis and determined the risk factors for being homozygous or compound heterozygous for M694V. RESULTS: A total of 263 (M/F =109/154) cases were included. The mean age at the onset of symptoms, follow-up duration, and time to diagnosis were 6.75 ± 3.9 (0.25-17) years, 51.78 ± 39.31 (6-166) months, and 9.23 ± 14.44 (1-132) months, respectively. The rates of parental consanguinity, positive family history for FMF, and FMF in a first-degree relative were 15%, 42%, and 31.4% respectively. The most common symptom was abdominal pain (85%). There was no difference between the growth parameters of the cases during the initial and final control periods. The most frequent alleles were M694V, E148Q, and V726A. The most common accompanying disease was IgA vasculitis (20%). Almost 90% of the cases fulfilled all the defined criteria. The rate of patients having a first-degree relative with FMF was higher, Hb values were lower, and the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values were higher during the attack period; the ESR and CRP values were higher in the attack-free period; and Pras disease severity scores were higher in homozygous or compound heterozygous cases carrying M694V. The presence of FMF in a first-degree relative increases the probability of being homozygous and compound heterozygous for M694V by a factor of 2.39; and each 1 unit increase in the Pras score increases this probability by a factor of 1.43. The threshold Pras score for this possibility is 5.5 (AUC = 0.651; 95% CI, 0.545-0.757; P = .006; sensitivity, 65%; specificity, 55%). CONCLUSION: M694V was the most common and severe mutation in our cohort. The presence of a first-degree relative with FMF and Pras scores ≥5.5 may predict a homozygous or compound heterozygous mutation for M694V.

The relation between the color M-mode propagation velocity of the descending aorta and coronary and carotid atherosclerosis and flow-mediated dilatation.

BACKGROUND: To improve clinical outcomes, noninvasive imaging modalities have been proposed to measure and monitor atherosclerosis. Common carotid intima-media thickness (CIMT) and brachial artery flow-mediated dilatation (FMD) have correlated with coronary atherosclerosis. Recently, the color M-mode-derived propagation velocity of descending thoracic aorta (AVP) was shown to be associated with coronary artery disease (CAD). METHODS: CIMT, FMD, and AVP were measured in 92 patients with CAD and 70 patients having normal coronary arteries (NCA) detected by coronary angiography. Patients with acute myocardial infarction, renal failure or hepatic failure, aneurysm of aorta, severe valvular heart disease, left ventricular ejection fraction <40%, atrial fibrillation, frequent premature beats, left bundle branch block, and inadequate echocardiographic image quality were excluded. RESULTS: Compared to patients with normal coronary arteries, patients having CAD had significantly lower AVP (29.9 +/- 8.1 vs. 47.5 +/- 16.8 cm/sec, P < 0.001) and FMD (5.3 +/- 1.9 vs. 11.4 +/- 5.8%, P < 0.001) and higher CIMT (0.94 +/- 0.05 vs. 0.83 +/- 0.14 mm, P < 0.001) measurements. There were significant correlations between AVP and CIMT (r =-0.691, P < 0.001), AVP and FMD (r = 0.514, P < 0.001) and FMD and CIMT (r =-0.530, P < 0.001). CONCLUSIONS: The transthoracic echocardiographic determination of the color M-mode propagation velocity of the descending aorta is a simple practical method and correlates well with the presence of carotid and coronary atherosclerosis and brachial endothelial function.

Noninvasive assessment of atherosclerosis in patients with isolated hypertension.

BACKGROUND: Endothelial dysfunction is considered the first stage in the development of atherosclerosis. Brachial artery flow-mediated dilatation (FMD) has been used to assess endothelial dysfunction. An impaired FMD response may reflect a vascular phenotype prone to atherosclerosis. The thickness of the common carotid intima-media (CIMT) as measured by ultrasound represents a marker of structural atherosclerosis. Recently, it has been shown that color M-mode propagation velocity measured along the origin of descending thoracic aorta (AVP) may reflect atherosclerosis. In this study, the effects of isolated hypertension on these atherosclerosis markers are investigated. METHODS: Fifty patients with newly diagnosed hypertension and forty healthy people were enrolled. Patients were evaluated with transthoracic echocardiography. Diastolic functions were evaluated by transmitral filling parameters of deceleration time (DT), E/A ratio, and isovolumetric relaxation time (IVRT). Carotid intima-media thickness, FMD, and AVP were measured. RESULTS: Age, gender, and BMI of both groups were similar. Compared to control group CIMT, DT and IVRT values were significantly higher, and FMD and AVP values were significantly lower in hypertensive patients. There were significant correlations between AVP and CIMT (r =-0.699, P < 0.001), AVP and FMD (r = 0.400, P < 0.001), and FMD and CIMT (r =-0.600, P < 0.001). Carotid intima-media thickness, AVP, and FMD were significantly correlated with systolic and diastolic blood pressures and DT and IVRT. CONCLUSIONS: In patients with isolated hypertension, AVP and FMD decrease and CIMT increases. In addition, CIMT is inversely correlated with AVP and FMD, and AVP is directly correlated with FMD.

[Successful lysis of a mobile left ventricular thrombus by slow infusion of low-dose tissue plasminogen activator]. / Sol ventriküldeki hareketli trombüsün düsük doz ve yavas infüzyonla verilen doku plazminojen aktivatörüyle basariyla çözülmesi.

There is no consensus on the management of intracardiac mural thrombi. A 59-year-old man underwent echocardiographic examination for right leg pain and pulse deficits in the right lower extremity, which showed severe left ventricular systolic dysfunction and a bell-shaped protruding mobile thrombus in the left ventricular apex. Due to high risk of surgery, 50 mg recombinant tissue-type plasminogen activator (rt-PA) was slowly infused over eight hours. Serial echocardiographic examinations showed a progressive decrease in the size of the thrombus within the first hours of rt-PA infusion, resulting in complete lysis after 24 hours. Low-dose and slow-infusion thrombolytic therapy may be an alternative therapy for left ventricular thrombi when surgery is not feasible.
