Evaluation of right ventricular function in patients with Behcet's disease by four-dimensional echocardiography.

AIM: Behcet's disease (BD) is a systemic disorder characterized by vasculitis, resulting in thickened vascular walls that reduce elasticity and impair function. BD can involve the cardiovascular system in three ways: cardiac, arterial, and venous. In this study, our objective was to evaluate the efficacy of pulmonary arterial stiffness (PAS) and pulmonary pulse transit time (PPTT) measures in demonstrating right ventricular functions in asymptomatic BD patients. We aimed to objectively evaluate right ventricular function in patients with BD using four-dimensional echocardiography (4DE). METHOD: This study included 40 patients diagnosed with BD and 40 healthy subjects. Demographic, clinical, laboratory, and echocardiographic parameters were compared. In addition to standard transthoracic echocardiographic evaluation, right ventricle quantification (RVQ) by using the 4DE and 2D-speckle tracking echocardiography were performed. RESULTS: The sPAP, 4D RVQ, and right ventricular strain values exhibited significant differences between the BD and control groups. Right ventricular end-diastolic diameter (RVDD), right ventricular end-systolic diameter (RVSD), right atrium (RA) area, right ventricular myocardial performance index (RVMPI), and PAS were increased in BD patients compared to the control group. Right ventricular ejection fraction (RVEF), right ventricular fractional area change (RVFAC), tricuspid annular plane systolic excursion (TAPSE), Tricuspid S', and PPTT were decreased in BD patients compared to control subjects. PPTT correlated with right ventricular free wall strain (RV-FWS) and PAS. In a multivariate linear regression analysis, PAS and RVFAC were found to be independent predictors of RVFWS. In addition, RVFAC and TAPSE are independent predictors for PPTT. CONCLUSION: Patients with BD may have elevated pulmonary arterial stiffness (PAS) in correlation with decreased PPTT. To ascertain the prognosis for these individuals, right ventricular (RV) functions must be evaluated. Measurements of RVFAC and RVEF via 4DE and deformation imaging techniques may be more useful in identifying subclinical impairment of RV. Individuals with BD, PAS, and PPTT may suggest a link between early pulmonary vascular remodeling and RV subclinical impairment.

Association between pan-immune-inflammation value and no-reflow in patients with ST elevation myocardial infarction undergoing percutaneous coronary intervention.

Noreflow is a condition associated with a poor prognosis in ST segment elevation myocardial infarction patients. It has been shown that many inflammatory markers and index such as procalcitonin, C-reactive protein, neutrophil to lymphocyte ratio, systemic immune inflammatory index (SII), are associated with noreflow. We used a brand-new index pan-immune-inflammation value (PIV) to retrospectively evaluate the relationship between PIV and noreflow. A total of 1212 patients were included for analysis. Noreflow was observed in 145 patients. In multivariate analysis, PIV (odds ratio (OR): 1.025; [1.002-1.115], p < 0.001), baseline ejection fraction (OR: 0.963; [0.934-0.993], p = 0.015), stent length (OR: 1.032; [1.010-1.054], p = 0.004), age (OR: 1.034; [1.014-1.053], p = 0.001) and pain to PCI time (OR: 1.003 [1.002-1.005], p < 0.001) were observed to be the independent predictors of noreflow. ROC curve analysis showed that the best cut off value of PIV for predicting noreflow was ≥889 with 77.2% sensitivity and 77.5% specificity (AUC, 0.828; 95% CI [0.806-0.849]). A ROC curve comparison analysis was performed to compare PIV and SII. The predictive power of PIV was higher than SII (differences between areas: 0.154; p < 0.001). According to our findings, an increase in PIV is an independent predictor of noreflow in patients with STEMI.

Evaluation of pulmonary artery stiffness and right ventricle functions in polycythemia vera patients by transthoracic echocardiography.

INTRODUCTION: Polycythemia vera (PV) is known to be a subgroup of chronic myeloproliferative neoplasms and is recognized as a cause of pulmonary hypertension (PH). Pulmonary artery stiffness (PAS) is a relatively new noninvasive echocardiographic index developed to evaluate the structural features and functions of the pulmonary vascular bed. In this study, we aimed to evaluate right ventricular (RV) functions and PAS in PV patients and healthy controls. METHODS: A group of 65 consecutive PV patients and 40 healthy controls were included in the study. RV global longitudinal strain (RVGLS) and RV free wall longitudinal strain were (RVFwLS) evaluated using two-dimensional (2D) strain echocardiography. RV volume, systolic and diastolic functions were evaluated with three-dimensional (3D) echocardiography. PAS was calculated using the maximum frequency shift (MFS) and acceleration time of the pulmonary artery flow trace. RESULTS: PAS values were significantly higher in the PV group than in the control group (25.2 ± 5.2 vs. 18.2 ± 4.2, p < .001). We found that tricuspid annular plane systolic excursion (TAPSE) (p < .001), RV fractional area change (p < .001) and RV ejection fraction (p < .001) measurements evaluated by 3D echocardiography were significantly lower in the PV group. CONCLUSION: In our study, PAS values were higher in PV patients than in the healthy control group. Patients with PV may have subclinical RV dysfunction, and PAS value can be used in the early diagnosis of PH and RV dysfunction in this patient group.

The importance of pulmonary pulse transit time in indicating right ventricular dysfunction and pulmonary arterial stiffness in rheumatoid arthritis.

SUBJECT: Rheumatoid arthritis patients are at risk of developing cardiovascular disease such as right heart failure and pulmonary hypertension (PH). Arterial stiffness can be used to assess pulmonary hemodynamics. Noninvasive approaches can also be used to assess pulmonary hemodynamics. Recently, there have been reports that pulmonary pulse transit time (PPTT) may also be a useful measure. This study aims to examine the effects of pulmonary hemodynamic alterations on PPTT in RA patients. METHODS: Forty RA patients and 40 healthy controls were included in the study. Sociodemographic characteristics, laboratory data, and echocardiographic examinations were performed in both groups. Conventional echocardiographic examination included left and right ventricular systolic and diastolic diameters, right ventricular myocardial performance index (RVMPI), right ventricular diastolic function, estimated pulmonary artery systolic pressure (sPAP), tricuspid annular plane systolic excursion (TAPSE), pulmonary artery stiffness (PAS), and PPTT. Right ventricular diastolic and systolic volumes, right ventricular ejection fraction (RVEF), and right ventricular fractional area change (RVFAC) were determined by four-dimensional echocardiography (4DE). RESULTS: There was no difference between the sPAP values of the patients. RVMPI and PAS were increased in RA patients compared with controls. The PPTT was shortened in RA patients and correlated with RVEF, RVFAC, RVMPI, TAPSE/sPAP, disease duration, and C-reactive protein (CRP). In univariate linear regression analysis, PPTT (p < .001) was thought to be an independent predictor of PAS. RVFAC, disease duration, and PAS were also independent predictors of PPTT. CONCLUSION: In RA patients, PPTT may be the first evidence of early abnormalities in pulmonary vascular hemodynamics. PPTT and PAS are the values that may predict each other in RA patients. Due to its more practical application, PPTT can be used instead of PAS to assess pulmonary hemodynamics.

The CHA2DS2-VASc risk score predicts successful endovascular treatment in patients with acute ischemic stroke.

OBJECTIVES: Acute ischemic stroke is a common cause of mortality and morbidity worldwide. Percutaneous endovascular intervention is an important treatment method in ischemic stroke. Endovascular procedure success is associated with the clinical outcome of the patients. The CHA2DS2-VASC score is an important score used to determine the risk of ischemic stroke in patients with atrial fibrillation. In our study, we aimed to evaluate the relationship between procedure success and CHA2DS2-VASC score in patients with acute ischemic stroke who underwent endovascular intervention. MATERIALS AND METHODS: A total of 102 consecutive patients who underwent endovascular intervention with acute ischemic stroke were included in the study. The admission CHA2DS2-VASc scores of the patients were recorded. After the procedure, the relationship between the TICI score and the CHA2DS2-VASc score was evaluated. RESULTS: CHA2DS2-VASc score was significantly higher in the group that resulted in unsuccessful endovascular intervention (2.78 ± 1.44, 5.02 ± 1.77 p < .001). Receiver-operating characteristics analysis revealed the cutoff value of CHA2DS2-VASc score ≥3 as a predictor of unsuccessful intervention with 76,6% sensitivity and 83,3% specificity, positive predictive value 50%, negative predictive value 84,6% (area under the curve [AUC]: 0.827,95% CI: 0.739-0.895, p < .001). In the multivariate analysis; atrial fibrillation ([ß] = 4.201; [CI]: 1.251-14.103, p = .020), CHA2DS2-VASc score ([ß] = 0.053; [CI]: 0.004-0.750, p = .030) were found independent predictors for unsuccessful intervention treatment. CONCLUSIONS: In our study, we showed that the CHA2DS2-VASc score is associated with the success of endovascular intervention in patients with acute ischemic stroke who underwent percutaneous endovascular treatment.

The relationship between bioelectrical impedance parameters and pulmonary artery stiffness in obese subjects.

OBJECTIVES: Obesity is a public health problem that needs to be treated and it occurs as a result of excessive fat accumulation in the body. The relationship between obesity and pulmonary hypertension is well known. The aim of this study is to evaluate the relationship between pulmonary artery stiffness, right ventricular functions and bioelectrical impedance parameters in obese, overweight, and healthy individuals. METHODS: In this study, 41 obese (17 female and 24 male, mean age 43.5±10.3), 39 overweight (20 female and 19 male, mean age 38.6±10.4), 34 healthy control group (19 female and 15 male, mean age 40.5±8.6) were included. Anthropometric measurements and bioelectrical impedance parameters of all participants were performed. Right ventricular functions and pulmonary artery stiffness were evaluated by using conventional echocardiography. RESULTS: Right ventricle myocardial performance index, pulmonary artery stiffness values were statistically different between groups. Positive correlation was observed between pulmonary artery stiffness and Body Mass Index, Waist and Hip circumferences. Significant negative correlation was observed between muscle to fat ratio and pulmonary artery stiffness. In the linear regression analysis, it was observed that the muscle to fat ratio was independent predictor of pulmonary artery stiffness (ß = -1.835; 95%CI(-2.434 - - .784); p < 0.001). CONCLUSIONS: This study showed that right ventricular function was impaired and pulmonary artery stiffness increased in obese individuals. These findings could be considered as early markers of pulmonary hypertension in obese patients who do not yet have clinical evidence of cardiovascular disease.

Fragmented QRS complexes are associated with subclinical left ventricular dysfunction in patients with Behcet's disease: Four-dimensional speckle tracking echocardiography.

BACKGROUND: Behcet's disease (BD) is a chronic systemic inflammatory disease in which early detection of cardiac involvement is essential. The aim of this study was to assess the left ventricular (LV) functions in BD patients using four-dimensional (4D) speckle tracking echocardiography (STE) and to test the correlation between LV dysfunction and the presence of QRS fragmentation. METHODS: This cross-sectional study included 64 Behcet's patients and 48 healthy volunteers. The BD group was divided into two subgroups depending on the presence (fQRS+) or absence (fQRS-) of fragmented QRS (fQRS). In both groups, left ventricular global area strain (LV-GAS), global radial strain (GRS), global longitudinal strain (GLS), and global circumferential strain (GCS) were obtained with 4D echocardiography. RESULTS: GAS, GRS, GLS, and GCS values were significantly different in Behcet's patients and in healthy volunteers. GLS and GAS values were lower in the fQRS+ than in the fQRS- group (-15.8 ± 1.8 and -17.9 ± 1.6, P = .001 vs -25.0 ± 3.1 and -29.2 ± 4.2, P < .001, respectively). The duration of disease was longer in fQRS+ than in fQRS- patients (120.8 ± 67.4 vs 71.0 ± 40.5, P < .001). Multiple linear regression analysis showed that fQRS and disease duration were independent predictors of LV-GAS. CONCLUSIONS: Four-dimensional STE may be helpful for the prediction of early cardiac dysfunction in patients with BD. The presence of fQRS may be an indicator of subclinical LV dysfunction.

Triphasic mitral flow pattern may indicate subclinical left ventricular systolic dysfunction.

PURPOSE: In this study, the presence and severity of left ventricular (LV) systolic dysfunction were investigated by speckle tracking echocardiography (STE) technique in patients with mitral triphasic mitral flow pattern (TMFP). The aim of the study was to evaluate the possible role of TMFP in the ethiopathogenesis of congestive heart failure. METHODS AND RESULTS: A total of 45 patients who were diagnosed with TMFP and 30 age- and gender-matched healthy volunteers were included in the study. The mean age in the study and control groups was 64 ± 12 and 62 ± 11 (P = .642), respectively. When echocardiographic parameters were evaluated, LV ejection fraction was found to be 63% ± 14 and 64 ± 12 (P = .745), in the study and control groups, respectively. LV end-diastolic and systolic diameters and LV mass index were also similar (P < .05). When LV diastolic parameters were compared, diastolic dysfunction was detected in 38 (84.4%) patients in the study population and 13 patients (43.3%) in the control group (P < .001). When STE findings were evaluated, both global longitidunal strain and global circumferential strain were significantly lower in the TMFP group when compared to controls (18.3 ± 1.7 vs 21.5 ± 1.5, P < .001 and 17.9 ± 1.6 vs 21.3 ± 2.1, P < .001, respectively). CONCLUSION: TMFP results in LV systolic dysfunction. Therefore, these patients may develop congestive heart failure in the long term. It will be rational that the patients with TMFP should be followed up more closely in terms of preventing manifest heart failure symptoms.

Subclinical left ventricular dysfunction in Sjögren's syndrome assessed by four-dimensional speckle tracking echocardiography.

OBJECTIVE: The aim of this study was to evaluate the left ventricular (LV) systolic strain by four-dimensional speckle tracking echocardiography (4D-STE) in order to provide the early detection of myocardial dysfunction in patients with Sjögren's syndrome (SS). METHODS: Forty consecutive patients with primary SS diagnosed at the rheumatology outpatient clinic and 35 age- and sex-matched healthy volunteers were included in the study. 4DSTE was performed, and global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and global area strain (GAS) were measured. 4DSTE results were compared with the healthy volunteers. RESULTS: No significant differences were observed between the GRS and GCS values of the two groups. A significant difference was observed in the GLS and GAS measurements between the two groups (P = .005 for GLS, P < .001 for GAS). Positive correlation was detected between disease duration and LV-GLS and LV-GAS. CONCLUSION: We demonstrated subclinical systolic dysfunction in SS patients by 4DSTE, which is a sensitive marker of ventricular dysfunction. Deterioration of the LV became more evident as duration of the disease increased. Therefore, we believe that a cardiac evaluation will be of benefit to patients with long-term SS.

Assessment of left atrial volume and function in patients with Sjögren's syndrome using three-dimensional echocardiography.

OBJECTIVE: We used real time, three-dimensional transthoracic echocardiography (3DTTE) to evaluate left atrial (LA) volume and mechanical function in patients with primary Sjögren's syndrome (SS). METHODS: We prospectively included 42 consecutive patients with primary SS and 42 controls who were similar in terms of basal characteristics. 3DTTE was used to assess LA function. RESULTS: Maximum LA volume, minimum LA volume, pre-atrial contraction LA volume, LA Active Stroke Volume (ASV), LA Total Stroke Volume (TSV), maximal left atrial volume index (LAVImax), Left atrial pre-contraction volume index, and Left atrial minimum volume index, ASV index, and TSV index were significantly higher in the SS group, and the LA Total Emptying Fraction, LA Expansion Index, and LA Passive Emptying Fraction were significantly lower. Although the active emptying fraction was higher in the SS group, the difference was not statistically significant. LAVImax was positive correlated with disease duration (r = .753). CONCLUSION: Left atrial function is impaired in SS patients and serves as an early marker of subclinical cardiac involvement.

Usefulness of platelet to lymphocyte ratio for predicting recurrence of atrial fibrillation after direct current cardioversion.

OBJECTIVE: Atrial fibrillation (AF) is the most common cardiac rhythm disorder with the associated risks of stroke and mortality. The usefulness of platelet to lymphocyte ratio (PLR), a recently described inflammatory marker, in predicting adverse cardiovascular events has been demonstrated in several studies. In the current study, we investigated the role of PLR in predicting recurrence after successful electrical cardioversion (ECV) in patients with non-valvular persistent AF. METHODS: A total of 287 patients with non-valvular persistent AF achieving restoration of the sinus rhythm after successful ECV were included in this study. At study entry, complete blood count, routine biochemistry tests, and transthoracic echocardiography (TTE) were performed routinely in all subjects. Patients were followed up for 6 months following the procedure and comparisons were performed between patients who recurred and who maintained the sinus rhythm (SR). RESULTS: At 6 months of follow-up, AF recurred in 108 patients, corresponding to a recurrence rate of 39%. Mean PLR values in the "AF recurrence group" (mean age 57.4 ± 12.0 years, 47.6% [n = 80] female) and in "SR maintenance" group (mean age 65.0 ± 9.4 years, 55.6% [n = 60] female) were 184.8 ± 44.2 and 103.3 ± 44.2, respectively, with a significant difference between the two groups (p < 0.001). In multiple regression analyses, PLR emerged as a risk factor associated with AF recurrence during the 6-month follow-up period after successful ECV (odds ratio [OR]: 3.029 (1.013-9.055 95% confidence interval [CI]), p = 0.047). When a cutoff value of 147 was used, the sensitivity and specificity of PLR for predicting AF recurrence were 83.3% and 84.5%, respectively. CONCLUSION: Elevated PLR is a marker of increased inflammation and may serve as a practical and inexpensive predictor for recurrence during 6 months of follow-up in patients with non-valvular persistent AF who had restoration of the sinus rhythm after successful ECV.

Association between fragmented QRS complexes and left ventricular dysfunction in healthy smokers.

OBJECTIVE: Smoking is a known risk factor for cardiovascular diseases and may cause myocardial damage independently of coronary artery disease. Fragmented QRS (fQRS) is an important marker of myocardial fibrosis, while speckle-tracking echocardiography is a method used to show subclinical left ventricle dysfunction. METHODS: Our study included 230 healthy individuals aged 18-40 years. The patients included were separated into two groups: those smokers (n = 130) and non-smokers (n = 100). After that healthy smokers group were divided into two groups: those with fQRS (n = 24) and those without (n = 106). In both groups, the arithmetic mean of three images was used to obtain the left ventricle global longitudinal strain (LV-GLS). The E/SRe ratio was also calculated and analyzed. RESULTS: There were significant differences between the smokers and non-smokers in terms of, E/SRe (55.7 ± 17.9 vs 50.3 ± 14.8; P = 0.015), LV-GLS (23.1 ± 1.9 vs 24.0 ± 1.7; P = 0.001), and fQRS (18.5% vs 6%; P = 0.005). As a result of subgroup analysis, pack-year history was higher in the fQRS positive group (16.7 ± 3.7 vs 11.2 ± 3.7, P < 0.001). While a negative correlation was observed between pack-year history and LV-GLS (r = -0.678, P < 0.001), there was a positive correlation between pack-year history and E/SRe (r = 0.730, P < 0.001). CONCLUSION: In conclusion, our study demonstrated that fQRS is a parameter that can be used to determine left ventricle subclinical systolic and diastolic dysfunction in smokers, and that left ventricle dysfunction is related to the duration and intensity of smoking.

Evaluation of left atrial volume and functions by real time three-dimensional echocardiography in patients with subclinical hypothyroidism before and after levothyroxine therapy.

BACKGROUND/AIMS: The cardiovascular system is one of the major targets of thyroid hormones. Subclinical hypothyroidism (SCH) is a common disease that can represent "early" thyroid failure. Our aim was to evaluate left atrial (LA) volume and functions in patients with SCH using real time three-dimensional echocardiography (RT3DE) and also to investigate changes in LA parameters after the levothyroxine treatment. METHODS: In total, 44 patients with SCH and 40 age- and gender-matched controls were studied. Assessments included history, physical examination and echocardiography. All patients with SCH were followed up with replacement therapy until the euthyroid status was achieved. RESULTS: In patients with SCH, LA total emptying volume, passive emptying volume, and passive ejection fraction were significantly reduced while LA minimal volume, active emptying volume, and active emptying fraction were significantly increased than in control group. Following the levothyroxine treatment, LA volume and function parameters were observed to be significantly improved. A negative correlation between the change of thyroid stimulating hormone (TSH) and change of LA active emptying volume and a positive correlation between the change of TSH level and change of LA passive emptying volume were found. CONCLUSION: It was shown that volume and functions of LA were impaired in patients with SCH. However, impaired parameters were improved after the levothyroxine treatment. These findings may be indicative of subclinical heart involvement that could lead to functional and structural changes in patients with SCH.

Prediction of no-reflow and major adverse cardiovascular events with a new scoring system in STEMI patients.

BACKGROUND: No-reflow is associated with a poor prognosis in STEMI patients. There are many factors and mechanisms that contribute to the development of no-reflow, including age, reperfusion time, a high thrombus burden, Killip class, long stent use, ejection fraction ≤40, and a high Syntax score. In this study, we aimed to evaluate the parameters associated with no-reflow prediction by creating a new scoring system. METHODS: The study included 515 consecutive STEMI patients who underwent PCI; 632 STEMI patients who had undergone PCI in another center were included in the external validation of the scoring system. The correlations between 1-year major adverse cardiac events and low/high risk score were assessed. RESULTS: In this study, seven independent variables were used to build a risk score for predicting no-reflow. The predictors of no-reflow are age, EF ≤40, SS ≥22, stent length ≥20, thrombus grade ≥4, Killip class ≥3, and pain-balloon time ≥4 h. In the derivation group, the optimal threshold score for predicting no-reflow was >10, with a 75% sensitivity and 77.7% specificity (Area under the curve (AUC) = 0.809, 95%CI: 0.772-0.842, P < 0.001). In the validation group, AUC was 0.793 (95%CI: 0.760-0.824, P < 0.001). CONCLUSION: This new score, which can be calculated in STEMI patients before PCI and used to predict no-reflow in STEMI patients, may help physicians to estimate the development of no-reflow in the pre-PCI period.

Epicardial fat thickness: A new predictor of successful electrical cardioversion and atrial fibrillation recurrence.

OBJECTIVE: In recent years, epicardial fat tissue (EFT) has been found to be strongly associated with the development of atrial fibrillation (AF) and post-ablation long-term recurrence. The current study investigated the procedural success rate of electrical cardioversion (ECV) and potential predictors of treatment failure in patients with nonvalvular persistent AF. METHODS: A total of 262 nonvalvular persistent AF patients who were scheduled for elective ECV were included in this prospective study. Routine transthoracic echocardiography was performed before the procedure and EFT thickness was measured. The presence of left atrial appendage thrombus was evaluated by transesophageal echocardiography. The patients were followed up for 6 months to examine any recurrence after ECV. RESULTS: The success rate of ECV was 85% and the recurrence rate was 35% during the 6-month follow-up period. The mean EFT thickness was 8.67 ± 1.2 mm in the persistent AF group with unsuccessful ECV and 6.81 ± 0.8 in the patients in whom sinus rhythm (SR) was maintained, the EFT was significantly thicker in the AF group (P = 0.001). EFT (P = 0.001) and left ventricular end-diastolic diameters (LVEDD) (P = 0.001) were significantly different between those who had maintained SR and those with recurrent AF during the 6-month follow-up period after ECV. In the multiple logistic regression analysis, LVEDD (odds ratio [OR]: 1.320 (1.023-1.703 95% confidence interval [CI]), P = 0.032)] and EFT [OR: 3.029 (1.013-9.055 95% CI), P = 0.047)] were identified as independent predictors of successful ECV. CONCLUSION: Epicardial fat tissue thickness can be effectively used for the prediction of successful ECV and AF recurrence during follow-up in AF patients.

Prediction of postoperative atrial fibrillation with left atrial mechanical functions and NT-pro ANP levels after coronary artery bypass surgery: A three-dimensional echocardiography study.

OBJECTIVE: Postoperative AF (POAF) is the most common cause of morbidity after coronary artery bypass surgery. In this study, we aimed to show the relationship between POAF and N-terminal pro-atrial natriuretic peptide (NT-pro ANP) levels and the relationship between mechanical functions and left atrial volume measured using preoperative three-dimensional echocardiography (3D ECHO) among patients that will undergo isolated coronary artery bypass grafting (CABG) in elective conditions. METHOD: Sixty-six consecutive patients (51 male, 15 female) who were decided to undergo CABG and had normal sinus rhythm were involved in the study. Patients were followed by continuous electrocardiography monitoring and daily electrocardiogram. LA volume and mechanical functions were calculated with 3D ECHO. In addition, for the analysis of plasma levels of NT-pro ANP, blood samples were collected before the surgery. RESULTS: During follow-up after the operation, 15 patients (22.7%) had postoperative atrial fibrillation. LA Vmax, Vmin, VpreA values were higher (P < .001, P = .004, P < .001 respectively) Also in POAF-developed group and SR group, LAVI values were 27.56 ± 4.2 and 20.7 ± 4.64 mL/m2 , respectively (P < .001). In POAF-developing group, NT-pro ANP levels were significantly higher (P < .001). In multiple logistic regression analysis, age (ß = 0.355, P = .007) and LAVI (ß = 0.668, P = .012) are independent predictors of POAF. CONCLUSION: It was found that 3D echocardiography can be used as a helping noninvasive method to show subclinical atrial volume and mechanical dysfunction in patients undergoing CABG. Also, blood levels of NT-pro ANP in POAF group were increased.

Association between Fragmented QRS and Left Ventricular Systolic Function in Patients with Erectile Dysfunction.

PURPOSE: The aim of this study was to investigate the association between fragmented QRS and left ventricular (LV) systolic function in patients with erectile dysfunction (ED). METHODS: A total of 106 patients with ED and without a history of coronary artery disease (CAD) were compared with 54 age- and gender-matched healthy controls. LV systolic function was evaluated using speckle tracking echocardiography via global longitudinal strain (GLS) and global circumferential strain (GCS). The patients with ED were compared with healthy controls. The study group was further subdivided into fQRS (+) and fQRS (-) groups and compared with each other. RESULTS: The frequency of fQRS was significantly higher in the patients with ED (p = 0.01). The frequency of fQRS was higher in the patients with mild and moderate ED, and significantly higher in those with severe ED (p < 0.001). LV-GLS (%) was 17.46 ± 1.37 and 20.05 ± 1.42 in the fQRS (+) and fQRS (-) groups, respectively (p ≤ 0.001). LV-GCS (%) was 17.33 ± 0.81 and 18.55 ± 0.92 in the fQRS (+) and fQRS (-) groups, respectively (p ≤ 0.001). fQRS and age were independent predictors of LV-GLS. CONCLUSIONS: The frequency of fQRS was higher in the patients with ED even in the absence of overt CAD. In the patients with ED, the fQRS (+) group had significantly lower values of LV-GLS and LV-GCS. These results indicate that presence of fQRS is associated with subclinical LV dysfunction in patients with ED.

Imaging behind occluded areas with an iatrogenic perforated balloon: A safe, practical, and simple new method of visualizing the distal lumen in total occlusion.

OBJECTIVE: In the present study, we investigated the effectiveness and reliability of a new method that reveals whether guidewire advanced distal to the lesion is in the lumen in patients with acute (ATO) or chronic coronary total occlusion (CTO). METHODS: Forty-one patients with symptomatic ATO and 22 patients with CTO who were admitted into our catheterization laboratory between January 2016 and March 2017 were included. In patients in whom antegrade filling could not be demonstrated after passing 0.014″ guidewire beyond the total lesion, a 1.25 × 15 mm balloon was punctured with a needle outside the operative field to visualize the total lesion. This perforated balloon was then used to deliver an opaque substance through this hole to visualize the distal part. RESULTS: The mean age of our 63 patients was 66 ± 12 years. They had diabetes (57%), hypertension (100%), and a history of PCI (85%). The mean procedural time was 27 ± 6.8 min, and the mean volume of contrast material used was 93.9 ± 24 mL. This technique was 100% successful in accurately demonstrating the distal lumen and preventing complications. CONCLUSION: This new method we developed is much simpler and more useful than other methods for visualization of the true lumen because we can re-orient the balloon at the time of opaque injection and use 190 cm guidewire without additional costs. Additionally, one balloon is sufficient for the operation.

Association between metabolic syndrome and fragmented QRS complexes: Speckle tracking echocardiography study.

BACKGROUND: Metabolic syndrome (MetS) is an endocrinological disease with both metabolic and physiological components. Previous studies have shown a relationship between MetS and left ventricular (LV) dysfunction. A fragmented QRS (fQRS) is a reliable electrocardiogram (ECG) finding with the importance of an indicator of myocardial fibrosis and scarring. In this study, we examined the utility of speckle tracking echocardiography (STE) in assessing LV function in MetS patients with fQRS. METHODS: The 164 consecutive MetS patients included in the study. They were separated into two groups; those with (n=33) and those without (n=131) fQRS. The two groups were compared by obtaining LV strain values with STE. RESULTS: Statistically significant differences between the fQRS (-) and fQRS (+) groups were identified for LV global longitudinal strain (LV-GLS) (p<0.001), maximum left atrial volume index (maxLAVI) (p≤0.001), strain rate during isovolumic relaxation period (SRivr) (p<0.001), and the E/SRivr ratio (p<0.001). In the multiple linear regression analysis, fQRS (ß=-1.456, p=0.003), diabetes mellitus (ß=-0.973, p=0.015), hypertension (ß=-0.820, p=0.015) and MaxLAVI (ß=-0.142, p=0.018) were independent predictors of LV-GLS. However, fQRS (ß=21.995, p<0.001), MaxLAVI (ß=3.090, p<0.001), and E/Em ratio (ß=3.326, p<0.001) were also independent predictors of E/SRivr. CONCLUSIONS: The results of this study showed that LV dysfunction was more common in MetS patients with fQRS. MetS patients, and especially those who are fQRS (+), should thus be closely monitored for subclinical LV systolic and diastolic dysfunction.

Effects of the coronary collateral circulation on the Tp-e interval and Tp-e/QT ratio in patients with stable coronary artery disease.

BACKGROUND: The clinical utility of the Tp-e interval and Tp-e/QT ratio in the risk stratification of ventricular arrhythmic events is controversial. Therefore, we investigated the impact of CCC on these electrocardiographic indexes in the course of stable CAD. METHODS: Two hundred three consecutive patients with stable CAD who underwent coronary angiography and had documented total occlusion of one of the major coronary arteries were enrolled in this prospective cross-sectional study. The Tp-e interval and Tp-e/QT ratio were measured by 12-lead electrocardiogram. RESULTS: The Tp-e interval, cTp-e interval, Tp-e/QT ratio, and cTp-e/QT ratio were lower in the grade 3 CCC group compared with the others in all leads. Multivariate linear regression analyses was performed to identify the clinical factors affecting the cTp-e interval and was indicated that age (ß = 0.261, P < 0.001), male sex (ß = 0.334, P < 0.001), poor Rentrop grade (ß = -0.228, P < 0.001), and NLR (ß = 0.137, P = 0.027) were independent predictors of a prolonged cTp-e interval. CONCLUSION: It could be concluded that the decreased dispersion of ventricular repolarization might contribute to the lower incidence of ventricular arrhythmias and SCD in CAD patients with a good CCC.
