RESUMO
INTRODUCTION: Pregnancy is a process that can cause several physiologic changes to the cardiovascular system such as ventricular hypertrophy and dilation of cardiac chambers. Although there are studies about pregnancy-related changes in echocardiographic examination; there is no data about the long-term effects of parity on these alterations. Therefore, we evaluated the long-term effect of pregnancy on right ventricular (RV) dilation and RV hypertrophy and their relation to the parity number. METHODS: This prospective study included a total of 600 women (200 consecutive women who had no parity, 200 women who had a parity number of 1 to 4 and 200 women who had a parity number of more than 4). Right chambers' measurements were compared between the groups. RESULTS: In echocardiographic analysis, RV and right atrial dimensions and areas and RV wall thickness were higher in parous women. On the other hand, RV systolic function parameters were significantly lower in parous women. These significant changes showed a gradual increase or decrease by increasing parity number. By multivariate hierarchical logistic regression analysis, the four independent factors that increased the risk of RV dilation were age (OR: 1.16 CI: 1.10-1.20), body mass index (OR: 1.05, CI: 1.02-1.08), smoking (OR: 1.87, CI: 1.28-4.02), and giving a birth (OR: 3.94 CI: 1.82-8.81). There was also independent relationship between the number of parity and RV hypertrophy even after adjustment for several confounders. CONCLUSION: Pregnancy-related physiological changes mostly resolve after delivery. This study about long-term effects of pregnancy on RV has demonstrated that there is a significant relation between the number of parity and either RV dilation or RV hypertrophy. Each parity had also additive effect on these changes.

There is minimal information available regarding the early effects of bronchial asthma (BA) and its treatment on cardiac function in children. We used two-dimensional speckle-tracking echocardiography (2D-STE) to evaluate cardiac function before and after the treatment of childhood BA. We enrolled 44 children with moderate and severe BA who had not been treated over the preceding 3 months or who were newly diagnosed. All children received the same treatment (that recommended by the Global Initiative for Asthma [GINA] in 2017). All children also underwent transthoracic 2D-STE before treatment and 6 months later. Clinical data were compared before and after treatment. After treatment, significant increases were evident in right ventricular (RV) systolic and diastolic strain, as well as the systolic strain rate. Before and after treatment, the RV global longitudinal systolic strains were - 22.8 ± 3.6 and - 25.1 ± 4.5, respectively (p = 0.036); the RV global longitudinal diastolic strains were - 18.5 ± 6.0 and - 21.5 ± 5.2, respectively (p = 0.038); and the RV systolic strain rates were - 1.26 ± 0.4 and - 1.12 ± 0.3, respectively (p = 0.025). After treatment, significant increases were observed in the right atrial (RA) peak longitudinal strain and strain rate. Before and after treatment, the RA peak atrial longitudinal strains were 32.5 ± 10.8 and 44.7 ± 11.2, respectively (p = 0.042) and the RA longitudinal strain rates were - 1.6 ± 0.3 and - 2.0 ± 0.5, respectively (p = 0.041). RV and RA subclinical dysfunction may develop in children with early-stage BA. However, asthma treatment appears to improve such dysfunction. In children with BA, clinical and subclinical changes in cardiac functions can be easily detected via 2D-STE.
RESUMO
BACKGROUND: Atrial fibrillation (AF) is a common complication of ST-segment elevation myocardial infarction (STEMI), and AF might require anticoagulant treatment in some conditions. STUDY QUESTION: There are no clear recommendations about vitamin K antagonist (VKA) use in patients with STEMI who complicated with new-onset transient AF. In this study, we examined the association of concomitant use of VKA and dual antiplatelet therapy (DAPT) with clinical outcomes of this patient population. STUDY DESIGN: A total of 4086 patients with STEMI who underwent primary percutaneous coronary intervention retrospectively investigated. Among these patients, a total of 286 patients who developed new-onset transient AF during hospitalization were enrolled. VKA group consisted of 116 patients treated with warfarin, aspirin, and clopidogrel, and DAPT group consisted of 170 patients treated with aspirin and clopidogrel. MEASURES AND OUTCOMES: One-year mortality, ischemic stroke, major, and minor bleeding were determined as clinical outcomes. RESULTS: Although VKA group had proportionally lower mortality (17.2% vs. 20.0%) and ischemic stroke (7.8% vs. 11.8%) compared with DAPT group, the differences did not reach to statistical significance, whereas the 1-year major bleeding had higher rates at VKA group and that had 3.5-times higher major bleeding than DAPT group. This relationship was persisted after multivariable analysis (hazard ratio = 3.37, 95% CI, 1.76-10.04, P = 0.012). CONCLUSIONS: There is not a widely accepted treatment algorithm in patients with STEMI who complicated with new-onset AF in clinical guidelines. The current study indicated that transient form of new-onset AF might not require long-term VKA. Besides, addition of VKA to DAPT therapy may increase the rates of major and minor bleeding.

OBJECTIVE: To assess coronary artery calcification (CAC) in patients with acute pulmonary embolism and determine whether this correlates with right ventricular dilation (RVD) and mortality. METHODS: Computed tomography pulmonary angiography scans of 330 patients were used to perform retrospective assessment of the pulmonary artery computed tomography obstruction index (PACTOI), the right/left ventricle diameter ratio, the diameter of the pulmonary trunk, and the ordinal CAC score. RESULTS: Age (P < 0.001), urea level (P < 0.001), D-dimer level (P = 0.006), diameter of the pulmonary trunk (P < 0.001), and PACTOI (P < 0.001) were significantly higher in the RVD-positive patient group. We found a significant relation between increased CAC score and increased mortality (P = 0.038). Left-sided CAC was detected much more often in RVD-positive patients (P = 0.008). CONCLUSIONS: Coronary artery calcification is common in patients with acute pulmonary embolism, especially when those patients are also RVD-positive. A significant relation was found between RVD and left-sided CAC.

BACKGROUND: Although aortic valve replacement (AVR) when successfully performed boasts low mortality rates in selected patients, prosthesis-patient mismatch (PPM) can be found in the majority of these individuals. Limited research is available supporting the benefit of two-dimensional speckle tracking echocardiography (2D-STE) in patients with severe PPM. This study sought to assess myocardial strain using 2D-STE to determine the relationship between subclinical left ventricular (LV) dysfunction and aortic PPM in patients undergoing AVR with preserved LV ejection fraction. MATERIAL AND METHODS: We retrospectively examined all consecutive patients with isolated AVR who presented to our center from 2005 to 2018. The data of 1086 patients were analyzed. Severe PPM was defined as an indexed effective orifice area of 0.65â¯cm2/m2 or less. As a result of the detailed assessment, 54 patients meeting the eligibility criteria were included in the study. Baseline data were collected and compared between the two groups of patients with severe PPM (nâ¯= 27) and those with normofunctional aortic prosthesis valve as a control group (nâ¯= 27). All patients underwent baseline echocardiography. Global longitudinal strain (GLS) and global circumferential strain (GCS) were evaluated by 2D-STE. RESULTS: When compared with controls, patients with severe PPM had significantly decreased GLS (18.6⯱ 2.9 vs. 21.4⯱ 2.1; pâ¯<â¯0.01) and GCS (17.2⯱ 3.6 vs. 21.7⯱ 2.1; pâ¯<â¯0.01) values. CONCLUSION: In addition to standard clinical and echocardiographic parameters, GLS and GCS suggest subclinical dysfunction and have incremental value in patients with severe PPM.

OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is a life-threatening complication that leads to comorbidities and prolonged hospital stay lengths in the setting of peripheral interventions. The presence of some CI-AKI risk factors has already been investigated. In this study, we evaluated the predictors of CI-AKI after carotid artery stenting. METHODS: A total of 389 patients with 50% to 99% carotid artery stenosis who underwent carotid artery stenting were included in this study. Patients were grouped according to CI-AKI status. RESULTS: CI-AKI developed in 26 (6.6%) patients. Age, baseline creatinine level, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were higher and estimated glomerular filtration rate, haemoglobin and lymphocyte count were lower in CI-AKI patients. In the multivariate regression analysis, the neutrophil-to-lymphocyte ratio triggered a 1.39- to 2.63-fold increase in the risk of CI-AKI onset (p < 0.001). CONCLUSIONS: The neutrophil-to-lymphocyte ratio may be a significant predictor of CI-AKI in patients with carotid artery stenting and higher neutrophil-to-lymphocyte ratio values may be independently associated with CI-AKI.

BACKGROUND: Inflammatory mechanisms play an important role in both atherosclerosis and stroke. There are several inflammatory peripheral blood count markers associated with carotid artery stenosis degree, symptomatic carotid artery lesions and carotid artery stent restenosis that reported in previous studies. However, the prognostic role of the blood cell counts and their ratios in predicting in-hospital and long-term outcomes in patients undergoing carotid artery stenting (CAS) has not been comprehensively investigated. Systemic immune-inflammation index (SII) proved its' efficiency in patients with solid tumors and its' role was rarely examined in cardiovascular disorders and stroke. The current study evaluated the effect of this novel risk index on in-hospital and long-term outcomes in a large patient population who underwent CAS. METHOD: A total of 732 patients with carotid artery stenosis who underwent CAS were enrolled to the study. SII was calculated using the following formula: neutrophil-to-lymphocyte ratio × total platelet count in the peripheral blood (per mm3) and the patients were stratified accordingly: T1, T2 and T3. In-hospital and 5-year outcomes were compared between the tertiles of SII. RESULTS: During the hospitalization, major stroke, ipsilateral stoke, myocardial infarction, death and major adverse cardiovascular events (MACE) rates were significantly higher in high SII level (T3) compared to SII levels (T1 and 2). In long-term outcomes, ipsilateral stroke, major stroke, transient ischemic attack, death, and MACE were significantly higher in the patients with higher SII level (T3). The 5-year Kaplan-Meier overall survival for T1, T2, and T3 were 97.5%, 96.7% and 86.0% respectively. In-hospital and 5-year regression analyses demonstrated that high SII was independently associated with MACE and mortality. CONCLUSION: SII was independently associated with in-hospital and long-term clinical outcomes in patients undergoing CAS. Immune and inflammation status, as assessed easily and quickly using SII, has a good discriminative value in these patients.

BACKGROUND: We aimed to investigate the relationship between hemoglobin A1c (HbA1c) and coronary thrombus load in type-2 diabetes mellitus (T2DM) patients with non-ST segment elevation myocardial infarction (NSTEMI). MATERIALS AND METHODS: Ninety diabetic patients with NSTEMI were recruited for the study. They were separated into two groups according to HbA1c levels. Forty-seven patients having HbA1c ≤6.5% formed Group-I (35 male, mean age 58 ± 10.5 years) and the remaining 43 patients with HbA1c >6.5% formed Group-II (23 male, mean age 58 ± 11.1 years). Both the groups were evaluated in terms of thrombolysis in myocardial infarction (TIMI) thrombus score and Syntax score. RESULTS: Baseline patient characteristics were comparable in both the groups. TIMI thrombus score and Syntax score were higher in Group II than in Group I (3.2 ± 1.4 vs. 4.7 ± 0.5 and 20.2 ± 3.4 vs. 26.3 ± 3.0 respectively, P < 0.05). No significant difference was found in other parameters. In stepwise linear regression analysis, prepercutaneous coronary intervention (PCI) and post-PCI TIMI frame number and HbA1c were significantly related to the coronary thrombus scale. However, no significant relationship has been found between thrombus formation and hypertension, previous PCI history, pre-PCI heart rate, pre-PCI cholesterol status, and high-sensitive troponin T. CONCLUSION: In NSTEMI with T2DM, increased HbA1c (HbA1c >6.5%) is related with coronary thrombus in the target vessel. In those patient population, strict anticoagulation should be considered to prevent potential adverse events.
RESUMO
INTRODUCTION: The present research aimed to determine the relation between the use of angiotensin-converting enzyme inhibitors (ACE inh) and angiotensinogen receptor blockers (ARBs) and in-hospital mortality of hypertensive patients diagnosed with Covid-19 pneumonia. MATERIAL AND METHOD: In this retrospective study, we included 113 consecutive hypertensive patients admitted due to Covid-19 infection. In all patients, Covid-19 infection was confirmed with using reverse-transcription polymerase chain reaction. All patients were on ACE inh/ARBs or other antihypertensive therapy unless no contraindication was present. The primary outcome of the study was the in-hospital all-cause mortality. RESULTS: In total, 113 hypertensive Covid-19 patients were included, of them 74 patients were using ACE inh/ARBs. During in-hospital follow up, 30.9% [n = 35 patients] of patients died. The frequency of admission to the ICU and endotracheal intubation were significantly higher in patients using ACE inh/ARBs. In a multivariable analysis, the use of ACE inh/ARBs was an independent predictor of in-hospital mortality (OR: 3.66; 95%CI: 1.11-18.18; p= .032). Kaplan-Meir curve analysis displayed that patients on ACE inh/ARBs therapy had higher incidence of in-hospital death than those who were not. CONCLUSION: The present study has found that the use of ACE inh/ARBs therapy might be associated with an increased in-hospital mortality in patients who were diagnosed with Covid-19 pneumonia. It is likely that ACE inh/ARBs therapy might not be beneficial in the subgroup of hypertensive Covid-19 patients despite the fact that there might be the possibility of some unmeasured residual confounders to affect the results of the study.

BACKGROUND: Inflammation and malnutrition play a critical role in the outcomes of patients undergoing carotid artery stenting (CAS). Prognostic nutritional index (PNI) is commonly utilized to evaluate the peri-operative immune-nutritional status of patients undergoing colorectal cancer surgery and is independently associated with survival. We assessed the association between immune-nutritional status, indexed by PNI, and outcomes in CAS patients. METHODS: A total of 615 patients hospitalized for CAS in a tertiary heart center were enrolled in the study. PNI was calculated using the following formula: 10× serum albumin value (g/dL) + 0.005 × total lymphocyte count in the peripheral blood (per mm3). In-hospital and 5-year outcomes (ipsilateral stroke, major stroke, transient ischemic attack, myocardial infarction, and mortality) were compared between the tertiles of PNI. RESULTS: In-hospital outcomes were similar between the groups except the increased mortality in decreasing tertiles of PNI. During a mean follow-up duration of 51.1 months, the lower PNI tertile was related to unfavorable outcomes. After adjusting for multi-model Cox regression analysis, PNI persisted as an independent prognostic factor for mortality and major stroke. CONCLUSION: PNI was independently associated with long-term mortality and major stroke in CAS patients. Malnutrition and inflammation, which can be assessed easily and quickly using PNI, have an important prognostic value in the patients undergoing CAS.

BACKGROUND: There is not a widely accepted optimal rate of stent opening in patients underwent carotid artery stenting. In this study we evaluated the effect of carotid stent opening rate (CSOR) without performing post-dilation on in-hospital and long-term outcomes. METHODS: A total of 825 patient patients underwent carotid artery stenting without post-dilation enrolled to the study. The patients divided into two groups according to their final CSOR (50%â¯≤â¯Post-stent deployment (SD) <80% and 80%â¯≤â¯Post-SDâ¯≤â¯100%). In-hospital and 3-year outcomes were compared between the groups. RESULTS: During hospitalization, the rate of ipsilateral stroke, major stroke and transient ischemic attacks were similar between the groups (respectively; 6.2% vs. 4.1, Pâ¯=â¯0.190; 1.5% vs. 1.8, Pâ¯=â¯0.811; 1.5% vs. 1.9%, Pâ¯=â¯0.683). The 3-year Kaplan-Meier overall survival rates for the first and second groups were 87.6% and 84.4%, respectively (log rank test Pâ¯=â¯0.426). The 3-year Kaplan-Meier overall cumulative ipsilateral stroke rates for the first and second groups were 88.0% and 88.6%, respectively (log rank test Pâ¯=â¯0.409) CONCLUSION: Our study demonstrated that a CSOR higher than 50% without performing a post-dilation might be an effective therapeutic approach since there was not a significant difference regarding outcomes between the patients with a 50%â¯≤â¯Post-SD <80% and 80%â¯≤â¯Post-SDâ¯≤â¯100%. The need for post-stent balloon dilation might have been eliminated due to subsequent stent self-expansion.

OBJECTIVE: Buerger's disease is one of the worst diseases causing peripheral artery occlusions (especially lower extremity) with increased morbidity and mortality. Endovascular treatment of the diseased arteries gains preference over bypass surgery nowadays. Here, we aimed to present the clinical outcomes of 16 consecutive Buerger's disease patients underwent extended endovascular recanalization which is a new technique to restore direct blood flow to at least one foot artery, with the performance of angioplasty for each tibial and foot artery obstructions. METHODS: A total of 16 consecutive patients with confirmed diagnosis of Buerger's disease that percutaneously treated in our center between February 2014 and March 2018 were included in the study. The mean age of the patients was 44.25 ± 4.28 ranging from 36 to 50 years. After physical examination and complementary diagnostic tests, performance of extended angioplasty for occluded arteries was intended to restore direct blood flow to at least one of the blow-the-knee arteries. RESULTS: A successful extended endovascular treatment was performed in 20 of 22 limbs, achieving a technical success of 91%. All patients were successfully discharged without any complication. Mean follow-up duration was 21.43 ± 7.08 months. Reintervention was performed in one patient and minor amputation was needed in one of the failed limbs. Limb salvage rate was 100%. A significant difference was observed based on Rutherford classification, ankle brachial index, direct blood flow to foot, presence of ulcer and rest pain when compared before and after the intervention. CONCLUSION: We showed successful extended endovascular recanalization of Buerger's disease patients with a high technical success rate and sustained clinical improvement. Extended endovascular recanalization could be a therapeutic option in Buerger's disease patients, since they are not good candidates for surgery.

OBJECTIVE: The aim of this study was to compare the relationship between a novel electrocardiographic (ECG) parameter P wave peak time (PWPT) and classic P wave parameters with atrial fibrillation (AF). METHODS: A total of 140 individuals, including 70 patients with AF history and 70 healthy individuals without AF as the control group were included in the study. These groups were compared in terms of demographic characteristics, laboratory findings and ECG parameters. P wave parameters including; PR interval, P wave dispersion(PWDIS), P wave max duration(PWD) abnormal P wave axis, P-wave terminal force in lead V1 and a novel parameter PWPT were calculated from a 12-lead surface ECG recorded in all patients during sinus rhythm. RESULTS: PR duration, PWDIS, PWD and PWPT in lead V1 and D2 were found to be longer in AF group compared to the control group. The presence of a P-terminal force in lead 1(V1TF)â¯>â¯0.04â¯mm/s and abnormal P wave axis were shown to be significantly more frequent in the AF group. Univariate and multivariate regression analyses revealed independent relationship between the PWPT in lead V1 and AF(OR: 1.09, CI:1.01-1.17, p:0.024). In ROC curve analysis PWPTV1 above a cut-off level of 49.5msc predicted AF with a sensitivity of 79.4% and a specificity of 56.3% (Area Under Curve(AUC): 0.737, pâ¯<â¯0.001). CONCLUSION: In this study, we observed that PWPTV1 is longer in patients with paroxysmal AF than in controls.

BACKGROUND: The prognostic value of thrombolysis in myocardial infarction (TIMI) risk index (TRI) has been reported in patients with coronary artery disease. In this study, we evaluated the additional prognostic value of blood urea nitrogen (BUN) level to the TRI in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: We evaluated the in-hospital and long-term (3-year) prognostic value of modified TRI (mTRI) in patients with STEMI. The mTRI is calculated using the following equation; mTRI = (TRI × BUN)/10. Patients were stratified into 5 groups according to 20-point increments of mTRI. RESULTS: The patients with higher mTRI had significantly higher in-hospital and long-term mortality. The risk for in-hospital and long-term mortality was highest for those within the Q5 (36.8 and 42.3%, respectively) and it was significantly higher than all the other groups (p < .001 for both). CONCLUSIONS: In this study, the prognostic value of TRI has been augmented by multiplication of TRI with BUN/10. Therefore, we present a pilot study of association of mTRI with overall STEMI patients.

BACKGROUND: ST-segment elevation myocardial infarction (STEMI) complicated with cardiogenic shock (CS) remains as an unresolved condition causing high morbidity and mortality despite advances in medical treatment and coronary intervention procedures. In the current study, we evaluated the predictors of in-hospital mortality of STEMI complicated with CS. METHODS: In this retrospective study, we evaluated the predictive value of baseline characteristics, angiographic, echocardiographic and laboratory parameters on in-hospital mortality of 319 patients with STEMI complicated with CS who were treated with primary percutaneous coronary intervention. Patients were divided into two groups consisting of survivors and non-survivors during their index hospitalisation period. RESULTS: The mortality rate was found to be 61.3% in the study population. At multivariate analysis after adjustment for the parameters detected in univariate analysis, chronic renal failure, Thrombolysis In Myocardial Infarction (TIMI) post percutaneous coronary intervention (PCI) ≤2, plasma glucose and lactate level, blood urea nitrogen level, Tricuspid Annular Plane Systolic Excursion (TAPSE) and ejection fraction were independent predictors of in-hospital mortality. CONCLUSIONS: Apart from haemodynamic deterioration, angiographic, echocardiographic and laboratory parameters have an impact on in-hospital mortality in patients with STEMI complicated with CS.

OBJECTIVE: In this study, we aimed to determine the predictive value of the CHA2DS2VASc score for acute stent thrombosis in patients with an ST elevation myocardial infarction treated with a primary percutaneous coronary intervention (pPCI). METHODS: This was a retrospective study conducted among 3,460 consecutive patients with STEMI who underwent a pPCI. The stent thrombosis was considered a definite or confirmed event in the presence of symptoms suggestive of acute coronary syndrome and angiographic confirmation of stent thrombosis based on the diagnostic guidelines of the Academic Research Consortium. The stent thrombosis was classified as acute if it developed within 24 h. RESULTS: The mean CHA2DS2VASc score was 3.29 ± 1.73 in the stent thrombosis group, whereas it was 2.06 ± 1.14 in the control group (p < 0.001). In multivariable logistic regression analysis, CHA2DS2VASc scores ≥ 4 were independently associat ed with acute stent thrombosis (OR = 1.64; 95% CI 1.54-1.71, p < 0.001). In a receiver operating characteristic curve ana-lysis, the best cut-off value for the CHA2DS2VASc score was ≥4, with 60% sensitivity and 73% specificity. Of note, pa tients with a CHA2DS2VASc score of 4 had a 4.3 times higher risk of acute stent thrombosis compared to those with a CHA2DS2VASc score of 1. CONCLUSIONS: The CHA2DS2VASc score may be a significant independent predictor of acute stent thrombosis in patients with STEMI treated with a pPCI. Therefore, the CHA2DS2VASc score may be used to assess the risk of acute stent thrombosis in patients with STEMI following a pPCI.

Background: The Glasgow prognostic score (GPS), which is obtained from a combination of C-reactive protein (CRP) and serum albumin level, predicts poor prognoses in many cancer types. Systemic inflammation also plays an important role in pathogenesis of cardiovascular diseases. In this study, we aimed to investigate the effect of inflammation-based GPS on in-hospital and long-term outcomes in patients hospitalized in intensive cardiovascular care unit (ICCU). Methods: A total of 1004 consecutive patients admitted to ICCU were included in the study, and patients were divided into three groups based on albumin and CRP values as GPS 0, 1, and 2. Patients' demographic, clinic, and laboratory findings were recorded. In-hospital and one-year mortality rates were compared between groups. Results: Mortality occurred in 109 (10.8%) patients in in-hospital period, 82 (8.1%) patients during follow-up period, and thus, cumulative mortality occurred in 191 (19.0%) patients. Patients with a high GPS score had a higher rate of comorbidities and represented increased inflammatory evidence. In the multivariate regression model there was independent association with in-hospital mortality in GPS 1 patients compared to GPS 0 patients (Odds ratio, (OR); 5.52, 95% CI: 1.2â»16.91, p = 0.025) and in GPS 2 patients compared to GPS 0 patients (OR; 7.01, 95% CI: 1.39â»35.15, p = 0.018). A higher GPS score was also associated with a prolonged ICCU and hospital stay, and increased re-hospitalization in the follow-up period. Conclusion: Inflammation based GPS is a practical tool in the prediction of worse prognosis both in in-hospital and one-year follow-up periods in ICCU patients.

Background: Association of premature ventricular complexes (PVC) with left ventricular systolic dysfunction (LVSD) and efficacy of catheter ablation treatment have been demonstrated in studies. The role of left atrial (LA) mechanics in the etiopathogenesis of PVC-induced cardiomyopathy (PVC-CMP) as well as changes in LA mechanics with catheter ablation have not been studied before. Methods: A total number of 61 patients (Mean Age 43 ± 3) with idiopathic outflow tract (OT) PVCs undergoing radiofrequency catheter ablation (RFCA) were enrolled. ECG, 24 h Holter, and echocardiographic evaluation with left ventricular (LV) diastolic functions and LA volumetric assessments were performed before and three months after RFCA. Results: Along with a marginal increase in left ventricle ejection fraction (LVEF), improvement in diastolic functions and left atrial mechanics were observed in the study (LVEF 53 ± 7 versus 57 ± 6, p < 0.01) in short-term follow-up. The frequency of LV diastolic dysfunction (LVDD) decreased with catheter ablation (n = 5 to 0, p = 0.02). The overall LA function improved. Left atrium passive and overall emptying fraction (LAEF) increased significantly (0.32 ± 0.04 to 0.41 ± 0.04, p < 0.05 and 0.62 ± 0.04 to 0.65 ± 0.004, p < 0.05, respectively). Active LAEF decreased significantly (0.29 ± 0.005 to 0.24 ± 0.006, p < 0.05). Conclusions: The results of this study are indicative of "PVC-induced atriomyopathy" which responds to RFCA in short-term follow-up. Atrial dysfunction might play a role in symptoms and etiopathogenesis of LVSD.

OBJECTIVE: The combination of electrical phenomena and remote myocardial ischemia is the pathophysiological mechanism of ST segment changes in inferior leads in acute anterior myocardial infarction (MI). We investigated the prognostic value of ST segment changes in inferior derivations in patients with first acute anterior MI treated with primary percutaneous coronary intervention (PCI). METHODS: In this prospective single-center analysis, we evaluated the prognostic impact of ST segment changes in inferior derivations on 354 patients with acute anterior MI. Patients were divided into the following 3 groups according to admission ST segment changes in inferior derivations: ST depression (group 1), no ST change (group 2), and ST elevation (group 3). RESULTS: In-hospital multivariate analysis revealed notably high rates of in-hospital death for patients in group 3 compared to patients in group 2 (OR 2.5; 95% CI 1.6-7.6, p < 0.001). Group 1 and group 2 had similar in-hospital and long-term mortality rates. After adjusting for confounding baseline variables, group 3 had higher rates of 18-month mortality (HR 3.3; 95% CI 1.5-8.2, p < 0.001). CONCLUSION: In patients with a first acute anterior MI treated with primary PCI, ST elevation in inferior leads had significantly worse short-term and long-term outcomes compared to no ST change or ST segment depression.

Prosthetic valve thrombosis (PVT) is a potentially life-threatening complication associated with high morbidity and mortality. The CHA2DS2-VASc is a clinical score used to determine thromboembolism risk in non-valvular atrial fibrillation patients. Therefore; in this study, we aimed to determine predictive value of the CHA2DS2-VASc score for development of PVT in patients with mechanical prosthetic valve. This was a retrospective study included 417 consecutive patients with mechanic prosthetic valve in whom transesophageal echocardiography (TEE) was performed due to different clinical indications from January 2004 to June 2016. After evaluation according to exclusion criteria, 267 patients with mechanic prosthetic valve were enrolled in the study. The definitive diagnosis of the PVT was made as proposed by TEE finding. The study population was divided into two groups; PVT patients (154 patients) and control group (113 patients) with functional prosthetic valve. The CHA2DS2-VASc score was calculated for each patient from the hospital electronic database. The mechanical mitral valve thrombosis predictive value of variables including CHA2DS2-VASc score was tested in our study. The mean CHA2DS2-VASc score was significantly higher in PVT patients compared to control patients (2.51 ± 1.54 vs. 1.13 ± 1.21, p < 0.01). Both on univariate and multivariate analysis demonstrated that the CHA2DS2-VASc score is independently associated with PVT (p < 0.001 and p < 0.001, respectively). The patients whose CHA2DS2-VASc score ≥ 1-3 had 6.20 times higher risk for thrombus formation, and patients whose CHA2DS2-VASc score ≥ 4 had 16.6 times higher risk for thrombus formation compared to patients with CHA2DS2-VASc score = 0 (p < 0.001 and p < 0.001, respectively). The CHA2DS2-VASc score may be a significant independent predictor of PVT in patients with prosthetic valve and the CHA2DS2-VASc score ≥ 2.5 or more was associated with increased PVT in patients with prosthetic valve. Thus; it may be an applicable risk scoring system to assess the risk of development of PVT in patients with prosthetic valve.
