Awareness and Knowledge of Pneumococcal Vaccination in Cardiology Outpatient Clinics and the Impact of Physicians' Recommendations on Vaccination Rates.

AIM: We aimed to evaluate the awareness of pneumococcal vaccination (PCV13, PPSV23) in general cardiology outpatient clinics and impact of physicians' recommendations on vaccination rates. METHODS: This was a multicenter, observational, prospective cohort study. Patients over the age of 18 from 40 hospitals in different regions of Turkey who applied to the cardiology outpatient clinic between September 2022 and August 2021 participated. The vaccination rates were calculated within three months of follow-up from the admitting of the patient to cardiology clinics. RESULTS: The 403 (18.2%) patients with previous pneumococcal vaccination were excluded from the study. The mean age of study population (n = 1808) was 61.9 ± 12.1 years and 55.4% were male. The 58.7% had coronary artery disease, hypertension (74.1%) was the most common risk factor, and 32.7% of the patients had never been vaccinated although they had information about vaccination before. The main differences between vaccinated and unvaccinated patients were related to education level and ejection fraction. The physicians' recommendations were positively correlated with vaccination intention and behavior in our participants. Multivariate logistic regression analysis showed a significant correlation between vaccination and female sex [OR = 1.55 (95% CI = 1.25-1.92), p < 0.001], higher education level [OR = 1.49 (95% CI = 1.15-1.92), p = 0.002] patients' knowledge [OR = 1.93 (95% CI = 1.56-2.40), p < 0.001], and their physician's recommendation [OR = 5.12 (95% CI = 1.92-13.68), p = 0.001]. CONCLUSION: To increase adult immunization rates, especially among those with or at risk of cardiovascular disease (CVD), it is essential to understand each of these factors. Even if during COVID-19 pandemic, there is an increased awareness about vaccination, the vaccine acceptance level is not enough, still. Further studies and interventions are needed to improve public vaccination rates.

The Safety and Tolerability of Nebivolol in Hypertensive Patients with Coronary Artery Disease and Left Ventricular Ejection Fraction ≥ 40%: A Population-Based Cohort Study (Nebivolol-TR Study).

BACKGROUND: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction ≥ 40% in a Turkish cohort. METHODS: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction ≥ 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded. RESULTS: The mean age of the study population was 60.3 ± 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 ± 23.5/-5.1 ± 13.5 mmHg, and the resting heart rate was -12.1 ± 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%. CONCLUSION: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

Systemic immune-inflammation index predicts in-hospital and long-term outcomes in patients with ST-segment elevation myocardial infarction.

OBJECTIVE: This study examines the predictive value of the novel systemic immune-inflammation index (SII) in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: A total of 1660 patients with STEMI who underwent primary percutaneous coronary intervention (pPCI) were enrolled in the study. In-hospital and 3-year outcomes were compared between the four groups (Q1-4). The SII was calculated using the following formula: neutrophil*platelet/lymphocyte. RESULTS: The frequency of in-hospital cardiogenic shock, acute respiratory failure, acute kidney injury, ventricular arrhythmia, stent thrombosis, recurrent myocardial infarction, major adverse cardiac events and mortality were significantly higher in the high SII groups (Q3 and Q4). Logistic regression models demonstrated that Q3 and Q4 had an independent risk of mortality and Q4 had an independent risk of cardiogenic shock compared to Q1. Receiver operating characteristic analysis showed that the best cutoff value of SII to predict the in-hospital mortality was 1781 with 66% sensitivity and 74% specificity. Kaplan-Meier overall survivals for Q1, Q2, Q3 and Q4 were 97.6, 96.9, 91.6 and 81.0%, respectively. Cox proportional analysis for 3-year mortality demonstrated that Q3 and Q4 had an independent risk for mortality compared to Q1. CONCLUSION: SII, a novel inflammatory index, was found to be a better predictor for in-hospital and long-term outcomes than traditional risk factors in patients with STEMI undergoing pPCI.

Epicardial adipose tissue may predict new-onset atrial fibrillation in patients with ST-segment elevation myocardial infarction.

AIMS: In this study, we aimed to determine the relationship between EAT thickness in patients with STEMI who underwent primary percutaneous coronary intervention (pPCI) and the development of new-onset atrial fibrillation during hospital follow-up. MATERIAL AND METHODS: Four hundred and thirteen consecutive patients [284 men (69%) and 129 women (31%)] with a mean age of 59 ±â€Š11 years diagnosed with STEMI were included in this study. Atrial fibrillation developed in 52 (12.5%) patients during in-hospital follow-up and the remaining 361 patients were determined as the control group. There was no difference between the two groups in terms of age and sex. EAT thickness was measured using transthoracic echocardiography. Multiple regression analysis was performed to determine the independent predictors of atrial fibrillation. RESULTS: EAT thickness was higher in the group with atrial fibrillation than in the control group (P < 0.001). The SYNTAX risk score was higher in the atrial fibrillation group (P < 0.001). A positive correlation was observed between EAT thickness and SYNTAX score (r = 0.523, P < 0.001). In the logistic regression analysis, EAT was detected to be an independent predictor for the development of atrial fibrillation (odds ratio: 4.135, 95% confidence interval 1.245-8.176, P < 0.001). CONCLUSION: EAT thickness is an important marker of atrial fibrillation development in STEMI patients in the post-pPCI period. We think that EAT thickness can be used as a cardioembolic risk factor in STEMI patients.

Epicardial fat tissue may predict new-onset atrial fibrillation in patients with non-ST-segment elevation myocardial infarction.

OBJECTIVE: In recent years, epicardial fat tissue (EFT) has been found to be strongly associated with the development of atrial fibrillation (AF). It was also reported to be a predictor of cardiac arrhythmias in different clinical situations. However, in the current literature, the role of EFT thickness in the development of AF in patients with non-ST-segment elevation myocardial infarction (NSTEMI) has not been studied. In this study, we aimed to investigate the relationship between EFT thickness and the development of new-onset AF in patients with NSTEMI during in-hospital follow-up. METHODS: We enrolled 493 consecutive patients who were diagnosed NSTEMI in this study. During in-hospital follow-up, 68 patients developed AF, and the remaining 425 patients were determined as the control group. The thrombolysis in myocardial infarction (TIMI) risk score for NSTEMI was calculated. All clinical, echocardiographic, and laboratory parameters were compared between the 2 groups. RESULTS: EFT thickness was higher in the AF group than in the controls (p<0.001). The TIMI risk scores were higher in the AF group (p<0.001). Logistic regression analysis demonstrated that EFT was an independent determinant for the development of AF (odds ratio 3.521, 95% confidence interval 1.616-6.314, p<0.001). CONCLUSION: Incident AF was observed more frequently in patients with NSTEMI and higher EFT thickness. EFT was an important determinant of AF in patients with NSTEMI.

Epicardial fat tissue can predict subclinical left ventricular dysfunction in patients with erectile dysfunction.

BACKGROUND: Erectile dysfunction (ED) is an early form of atherosclerosis and subclinical myocardial dysfunction. Epicardial fat tissue (EFT) is associated with impaired left ventricular (LV) function, even in the absence of cardiovascular disease. The aim of this study was to investigate the association between EFT and LV systolic function in patients with erectile ED by speckle tracking echocardiography (2D-STE) method. METHODS: A total of 129 consecutive patients with ED were compared with 145 age- and sex-matched control subjects. ED was evaluated using the International Index of Erectile Function questionnaire. Thickness of EFT was measured by TTE. Global LV longitudinal strain (LV-GLS) and global LV circumferential strain (LV-GCS) were measured by 2D-STE method. RESULTS: The EFT thickness was significantly higher in the patients with ED (p <.01). LV-GLS and LV-GCS were revealed to be more deterioration in the ED group compared to controls (-18.2 ± 2.7 vs. (-21.1 ± 3.9, p<.001; -19.5 ± 4.1 vs. -21.9 ± 3.9, p<.001, respectively). It has been shown that EFT thickness is an independent predictor of LV dysfunction. CONCLUSIONS: These results indicate that EFT thickness is associated with subclinical LV systolic dysfunction in patients with ED.

Speckle-tracking echocardiography can predict atrial fibrillation in patients with supraventricular tachycardia.

PURPOSE: Atrioventricular nodal reentry tachycardia (AVNRT) is the most common supraventriculer arrhythmia in daily clinical practice. Comorbidity of AVNRT and atrial fibrillation (AF) has been well documented in some patients and AF development has been observed more frequently in AVNRT patients during their long-term follow-up. This study was conducted in order to investigate the left atrial two-dimensional-speckle-tracking echocardiographic (STE) parametres as the predictors of the occurence of AF in long-term follow-up in patients with spontaneously developed AF during AVNRT ablation. METHODS: Two hundred and thirty two consecutive AVNRT patients who developed spontaneous AF during ablation procedure were included in the study. The patients were followed up for a mean follow-up period of 6.2 ± 2.1 years. All patients were evaluated using the 2D-STE method. AF was developed in 34 patients during the follow-up period. Cox regression analysis was performed in order to identify the independent predictors of AF occurence. RESULTS: Left atrial LA-res, LA-pump, LA-SRs, LA-SRe, and LA-SRa values were found to be significantly decreased in the group of patients that developed AF during the follow-up period (p < .001 for all aforementioned values). Multivariate cox regression analysis revealed that LA-res (hazard ratio [HR], 0.367; 95% confidence interval [CI], 0.161-0.0.683, p < .001) and SRe (HR, 0.472; 95% CI, 0.346-0.825, p = .006) were independent risk factors associated with the occurrence of AF. CONCLUSION: In conclusion, it was demonstrated for the first time with this study that 2D-STE can effectively predict the development of AF in long-term follow-up in patients with spontaneously developed AF during AVNRT ablation.

Usefulness of CHA2DS2-VASc Score to predict clinical outcomes of patients undergoing carotid artery stenting.

The CHA2DS2-VASc score predicts stroke and mortality risk in several cardiovascular diseases regardless of atrial fibrillation. In this study, we aimed to investigate the ability of CHA2DS2-VASc score to predict in-hospital and long-term outcomes in patients undergoing carotid artery stenting (CAS). The study population included 558 patients undergoing CAS. The patients were stratified into three groups based on their CHA2DS2-VASc scores [low (≤ 2, n = 123), moderate (3-5, n = 355) and high (6-8, n = 80)]. In-hospital and 3-year outcomes were compared between the groups. In-hospital rates of ipsilateral and major strokes and death were significantly different between the groups (1.6% vs. 3.9% vs. 16.2%; 1.6% vs. 4.5% vs. 16.2%; 0.8% vs. 3.1% vs. 13.8%, p < 0.001 for all, respectively). At 3 years of follow-up, rates of ipsilateral and major strokes and death were significantly increased in patients with highscore compared to those with moderate and low scores (1.6% vs. 5.8% vs. 13%, p = 0.005; 0.8% vs. 5.2% vs. 13%, p = 0.001; 1.6% vs. 8.4% vs. 15.9%; p = 0.002, respectively). After adjusting for multi-model Cox regression analysis, CHA2DS2-VASc score persisted as an independent prognostic factor for mortality and major stroke in patients undergoing CAS. Higher CHA2DS2-VASc score predicted increased risk of in-hospital and 3- year stroke and mortality in patients undergoing CAS.

Presence of fragmented QRS may be associated with complex ventricular arrhythmias in patients with type-2 diabetes mellitus.

BACKGROUND: Ventricular arrhythmias (VAs) are frequent in diabetes mellitus (DM) patients. Myocardial fibrosis is one of the components of diabetic cardiomyopathy secondary to DM. Fragmented QRS (fQRS) on electrocardiography (ECG) has been shown to be a marker of myocardial fibrosis. In this study, we aimed to investigate the association between fQRS and complex VAs in patients with DM. METHODS: Three hundred and thirty-six consecutive patients who were diagnosed with DM were included in the study. The control group consisted of 275 age- and sex-matched healthy individuals. ECG and transthoracic echocardiography were performed in all the patients. fQRS was defined as additional R' wave or notching/splitting of S wave in two contiguous ECG leads. All the patients underwent 24-h Holter monitoring and VAs were classified using Lown's scoring system. Lown class ≥ 3 VAs were considered as complex VAs. RESULTS: As compared to the healthy individuals, prevalence of fQRS (37.5% vs. 6.9%, p < .001) and complex VAs (14% vs. 0%, p < .001) were significantly higher in patients with DM. Furthermore, complex VAs (28.4% vs. 6.4%, p < .001) were significantly higher in DM patients with fQRS. In multiple logistic regression analysis, DM duration (OR: 1.510, 95% CI:1.343 to 1.698; p < .001) and presence of fQRS (OR: 3.262, 95% CI: 1.443 to 7.376; p = .004) were independent predictors for complex VAs. CONCLUSIONS: The presence of fQRS may be associated with complex VAs in patients with DM. Therefore, fQRS may be used as a predictor of complex VAs and the risk of sudden death in patients with DM.

Increased epicardial adipose tissue thickness is associated with microalbuminuria in hypertensive patients with left ventricular hypertrophy.

OBJECTIVE: Epicardial adipose tissue (EAT) is a cardiometabolic risk factor, and its possible relationship with hypertension has been previously reported. Microalbuminuria (MA) is associated with target-organ damage, especially in patients with hypertension with left ventricular hypertrophy (LVH) and suggest endothelial dysfunction. This study aimed to investigate the relationship between echocardiographic EAT thickness and presence of MA in patients with hypertension. METHODS: A total of 297 newly diagnosed hypertension patients who applied to the outpatient clinic were enrolled consecutively in this study. Patients were divided into two groups regarding the presence of LVH in echocardiography. An age and gender matched control group was set including 156 healthy patients without HT. All subjects underwent transthoracic echocardiography for the measurement of EAT thickness. Spot urine samples were collected for the assessment of MA. RESULTS: In hypertensive patients with LVH, the EAT thicknesses (6.6 ± 1.8 vs 5.3 ± 1.5 vs 5.1 ± 1.3, p < .001; respectively) and prevalence of MA (41.2 vs 20.1 vs 3.2%; p < .001 respectively) were significantly higher than the other two groups. In hypertensive patiens without LVH, no relationship was found between the presence of MA and EAT thickness. In multivariate regression analyses, EAT thickness (OR: 3.141, 95%CI: 2.425-6.123, p < .001) and left ventricular mass index (OR: 1.339, 95%CI: 1.145-2.143, p = .003) were determined as independent predictors for MA development in hypertensive patients with LVH. CONCLUSION: Measurement of EAT thickness may help to identify high-risk hypertensive patients for target-organ damage especially among patients with LVH.

What should be the Optimal Carotid Stent Opening Rate Without Post-Dilation?

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% ≤ Post-stent deployment (SD) <80% and 80% ≤ Post-SD ≤ 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, P = 0.190; 1.5% vs. 1.8, P = 0.811; 1.5% vs. 1.9%, P = 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 P = 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 P = 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% ≤ Post-SD <80% and 80% ≤ Post-SD ≤ 100%. The need for post-stent balloon dilation might have been eliminated due to subsequent stent self-expansion.

Prognostic significance of pre-procedural prognostic nutritional index in patients with carotid artery stenting.

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.

Relationship between fragmented QRS complexes and ejection fraction recovery in anterior ST-segment elevation myocardial infarction patients undergoing thrombolytic treatment.

BACKGROUND: Acute anterior ST-segment elevation myocardial infarction (STEMI) is a life-threatening disease. Adverse cardiac events of acute anterior STEMI include cardiovascular death or worsening congestive heart failure. This study investigated the role of fragmented QRS complex (fQRS) in predicting insufficient ejection fraction (EF) recovery in acute anterior STEMI. METHODS: Patients with acute anterior STEMI who received thrombolytic therapy were prospectively enrolled in this study. Twelve-lead electrocardiography (ECG) was obtained from all patients during admission and 24 and 48 h after admission. We divided the patients into two groups according to the presence of fQRS appearance within 48 h: absence of fQRS in any lead (fQRS-), and its presence in two or more contiguous leads (fQRS+). All patients were evaluated with transthoracic echocardiography at admission, and at follow-up 6 and 12 months later. RESULTS: A total of 138 consecutive patients were included in the study. Seventy-three patients (52.9%) had fQRS in the ECG. EF recovery in the fQRS(+) group was significantly lower than that of the fQRS(-) group (39% vs. 43.9%, P < 0.001). Multiple logistic regression analysis showed that the fQRS (odds ratio: 4.147, 95% confidence interval: 1.607-10.697, P = 0.003) were an independent predictor of poor EF recovery. CONCLUSION: The presence of fQRS is an independent predictor for inadequate EF recovery in acute anterior STEMI patients undergoing thrombolytic treatment. Assessment of fQRS on surface ECG may be used in determining high-risk patients for poor EF recovery after acute anterior STEMI.

Fragmented QRS may be associated with complex ventricular arrhythmias in mitral valve prolapse.

BACKGROUND: Although mitral valve prolapse (MVP) is a benign disease, several studies have indicated its association with ventricular arrhythmias (VAs). Some histopathological studies have pointed to left ventricular fibrosis as the underlying cause of arrhythmia in MVP patients. Fragmented QRS (fQRS) on electrocardiography (ECG) has been shown to be a marker of myocardial fibrosis. This study aimed to investigate the association between fQRS and complex VAs in patients with MVP. METHODS: A total of 230 consecutive patients who were diagnosed with MVP were included in the study. The control group consisted of 302 healthy individuals matched according to age and sex. fQRS was defined as additional R' wave or notching/splitting of S wave in two contiguous ECG leads. All patients underwent 24-hour Holter monitoring and VAs were classified using Lown's scoring system. Lown class ≥3 VAs were considered as complex VAs. RESULTS: As compared to the healthy individuals, prevalence of fQRS (40% vs. 9.6%, P<0.001) and complex VAs (18.7% vs. 0%, P<0.001) were significantly higher in patients with MVP. Furthermore, complex VAs (35.9% vs. 7.2%, P=0.001) were significantly higher in MVP patients with fQRS. In multiple logistic regression analysis, the presence of bileaflet prolapse (OR: 2.567, 95%CI: 1.434 to 4.367; P=0.002) and presence of fQRS (OR: 3.021, 95%CI: 1.556 to 6.232; P<0.001) were independent predictors for complex VAs. CONCLUSIONS: The presence of fQRS may be associated with complex VAs in patients with MVP. Therefore, fQRS may be used in risk stratification of complex VAs in patients with MVP.

Colchicine's Effects on Electrocardiographic Parameters in Newly Diagnosed Familial Mediterranean Fever Patients : Colchicine may have Favourable Effects on Parameters Related to Ventricular Arrhythmias in New Diagnosed Familial Mediterranean Fever.

OBJECTIVE: Colchicine may prevent both recurrent serositis attacks and secondary amyloidosis in familial Mediterranean fever (FMF). Furthermore, colchicine may decrease the frequency of atrial fibrillation in some groups of patients without FMF. However, there is no study that evaluates the effect of colchicine on arrhythmogenic electrocardiographic indices in FMF. In this study, we evaluated the impact of 1 year of colchicine treatment on atrial and ventricular arrhythmogenic electrocardiographic (ECG) parameters in newly diagnosed FMF patients. MATERIALS AND METHODS: We enrolled 28 newly diagnosed FMF (20 female, mean age 31.4 ± 8.2 years) patients who fulfilled the modified Tel Hashomer criteria. Electrocardiographic, demographic and laboratory parameters were obtained at the first visit and at the end of the 1­year colchicine treatment. Herein, we assessed P wave dispersion (Pd) for atrial arrhythmia risk and peak-to-end interval of T wave (Tp-E), Tp-E/QT, Tp-E/QTc values for ventricular arrhythmia risk. RESULTS: Colchicine treatment significantly decreased Tp-E and Tp-E/QT values (p = 0.02 and p = 0.01, respectively) by the end of the 1­year treatment. However, Pd values did not change with treatment. CONCLUSION: Colchicine treatment may have a favourable effect on ventricular repolarisation indices that relate to ventricular arrhythmia and sudden death.

The presence of fragmented QRS may predict the recurrence of nonvalvular atrial fibrillation after successful electrical cardioversion.

OBJECTIVE: Atrial fibrillation (AF), the most common cardiac rhythm disorder, affects approximately 2% of the general population and is associated with increased risk of stroke and mortality as well as reduced exercise capacity and quality of life. After restoring normal sinus rhythm, a portion of these patients develops recurrent AF despite optimal medical treatment. In this study, we aimed to assess the relationship between the presence of fragmented QRS (fQRS) and AF recurrence following successful electrical cardioversion (ECV). MATERIAL AND METHODS: A total of 306 patients with nonvalvular persistent AF achieving restoration of the sinus rhythm after successful ECV were included in this study. After ECV, patients were monitored at least 6 months for recurrence. The patients were divided into two groups according to the presence of fQRS and compared for AF recurrence during follow-up. RESULTS: Patients were followed up for a mean time of 220 ± 113 days. AF recurred in 119 patients, corresponding to a recurrence rate of 38.8%. AF recurrence was found to be significantly increased in patients with fQRS as compared to those without fQRS (76.4% vs. 23.5%, p < .001). Furthermore, the presence of fQRS was higher in patients with recurrent AF as compared to others (57.1% vs. 11.2%, p < .001). In multiple regression analyses, the presence of fQRS was one of the independent predictors of AF recurrence (hazard ratio: 9.670, 95% CI: 4.714-19.837, p < .001). CONCLUSION: The presence of fQRS may be associated with the recurrence of AF after successful ECV in persistent nonvalvular AF patients.

Association between fragmented QRS complexes and left-ventricular dysfunction in anabolic androgenic steroid users.

Background: Anabolic androgen steroid (AS) use has adverse effects on left ventricular functions, such as fibrosis development. Fragmented QRS is an important marker of myocardial fibrosis, while speckle-tracking echocardiographyis a method used to show subclinical left ventricle dysfunction. In this study, we examined the the ability of fQRS + to detect left ventricle fibrosis by speckle tracking echocardiography (STE) in AS users.Methods: The study included a total of 181 healthy athletes. Athletes were divided into two groups as AS users (n = 89) and non-AS users (n = 92). Then, athletes using AS were divided into two groups as fQRS+ (n = 52) and fQRS- (n = 37). 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 analysed.Results: There were significant differences between the AS users and non-AS users 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). When subgroup analysis was performed, both LV-GLS and E/SRivr were found to be poor in the fQRS + group. When multiple linear regression analysis was performed, we determined fQRS as an independent predictor for LV-GLS and E/SRivr ratio.Conclusion: In conclusion, our study demonstrated that fQRS is a parameter that can beused to determine left ventricle subclinical systolic and diastolic dysfunction in AS users. It can be used for cessation of drug use, especially in long-term use.

Normal echocardiographic measurements in a Turkish population: The Healthy Heart ECHO-TR Trial.

OBJECTIVE: Normal reference values for the cardiac chambers are widely based on cohorts from European or American populations. In this study, we aimed to obtain normal echocardiographic measurements of healthy Turkish volunteers to reveal the age, gender, and geographical region dependent differences between Turkish populations and other populations. METHODS: Among 31 collaborating institutions from all regions of Turkey, 1154 healthy volunteers were enrolled in this study. Predefined protocols were used for all participants during echocardiographic examination. Blood biochemical parameters were also obtained for all patients on admission. The American Society of Echocardiography and European Association of Cardiovascular Imaging recommendations were used to assess the echocardiographic cardiac chamber quantification. RESULTS: The study included 1154 volunteers (men: 609; women: 545), with a mean age of 33.5±11 years. Compared to men, women had a smaller body surface area, lower blood pressure and heart rate, lower hemoglobin, total cholesterol, lower low-density lipoprotein (LDL) levels, and higher high density lipoprotein (HDL) levels. Cardiac chambers were also smaller in women and their size varied with age. When we compared the regions in Turkey, the lowest values of left cardiac chamber indices were seen in the Marmara region and the highest values were observed in the Mediterranean region. Regarding the right cardiac indices, the Mediterranean region reported the lowest values, while the Black Sea region and the Eastern Anatolia region reported the highest values. CONCLUSION: This is the first study that evaluates the normal echocardiographic reference values for a healthy Turkish population. These results may provide important reference values that could be useful in routine clinical practice as well as in further clinical trials. (.

Atrial electromechanical delay in patients undergoing heart transplantation.

BACKGROUND: We aimed to assess atrial electromechanical delay (AEMD) in patients who had undergone heart transplantation. METHODS: A total of 32 patients who underwent biatrial anastomosis heart transplantation (24 men, 8 women; mean age: 42±11 years) and 30 healthy volunteers (20 men, 10 women; mean age: 36±13 years) were included in the study. Atrial electromechanical coupling (PA), intra-AEMD, and inter-AEMD were measured. RESULTS: PA lateral (68±7 vs. 51±11 ms, p<0.01), PA septal (50±5 vs. 42±8 ms, p< 0.01) and PA tricuspid (39±6 vs. 36±9 ms, p<0.01), inter-AEMD (PA lateral-PA tricuspid) (27±7 vs. 10±4 ms, p<0.01), left intra-AEMD (PA lateral-PA septal) (18±7 vs. 10±4 ms, p<0.01), right intra-AEMD (PA septal-PA tricuspid) (13±5 vs. 5±3 ms, p<0.01) values were higher in patients who underwent heart transplantation than in a control population. CONCLUSION: Inter-AEMD and intra-AEMD were prolonged in patients who underwent heart transplantation as compared to a control population. This may explain the increased atrial fibrillation and other atrial arrhythmia incidences associated with the biatrial anastomosis heart transplantation technique and may contribute to the treatment of atrial fibrillation in this special patient group.

Intracardiac Thrombus in Behçet's Disease.

Behçet's disease (BD) is a chronic multisystem disease that presents with recurrent oral and genital ulceration and recurrent uveitis. The patients are often diagnosed in the range of 20-30 years of age and BD are more common in men.[1] BD has a worldwide distribution, but it is mainly observed in Mediterranean areas and Japan.[2] Involvement of skin, joints, nervous, respiratory, gastrointestinal, and cardiovascular systems is also recognised.[34] Although the vascular lesions are frequently observed in this disease, the cardiac involvement is rare and is associated with the poor prognosis.[5].
