Turkish Real Life Atrial Fibrillation in Clinical Practice: TRAFFIC Study.

BACKGROUND: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes. METHODS: The TRAFFIC study is a national, prospective, multicenter, observational registry. The study aims to collect data from at least 1900 patients diagnosed with atrial fibrillation, with the participation of 40 centers from Türkiye. The following data will be collected from patients: baseline demographic characteristics, medical history, vital signs, symptoms of AF, ECG and echocardiographic findings, CHADS2-VASC2 and HAS-BLED (1-year risk of major bleeding) risk scores, interventional treatments, antithrombotic and antiarrhythmic medications, or other medications used by the patients. For patients who use warfarin, international normalized ratio levels will be monitored. Follow-up data will be collected at 6, 12, 18, and 24 months. Primary endpoints are defined as systemic embolism or major safety endpoints (major bleeding, clinically relevant nonmajor bleeding, and minor bleeding as defined by the International Society on Thrombosis and Hemostasis). The main secondary endpoints include major adverse cardiovascular events (systemic embolism, myocardial infarction, and cardiovascular death), all-cause mortality, and hospitalizations due to all causes or specific reasons. RESULTS: The results of the 12-month follow-up of the study are planned to be shared by the end of 2023. CONCLUSION: The TRAFFIC study will reveal the prevalence and incidence, demographic characteristics, and risk profiles of AF patients in Türkiye. Additionally, it will provide insights into how current treatments are reflected in this population. Furthermore, risk prediction modeling and risk scoring can be conducted for patients with AF.

Serum sortilin as a predictor of stroke in patients with intermediate carotid artery stenosis.

BACKGROUND: Sortilin was an important molecular protein involved in the pathogenesis of atherosclerosis. Besides, serum sortilin was associated with adverse cerebrovascular events. Atherosclerotic stenosis in the carotid artery is a major etiology for ischemic stroke. The risk of stroke in patients with intermediate carotid artery stenosis (CAS) was unknown. Hence, the aim of the present study was to evaluate the relationship between serum sortilin levels and stroke in patients with intermediate CAS. METHODS: A total of 195 intermediate CAS patients were included in this cross-sectional study. The patients were divided into two groups as symptomatic (N = 95) and asymptomatic (N = 100) patients. Patients with a transient ischemic attack (TIA), retinal ischemic event, or ischemic stroke resulting from the narrowed carotid artery were considered to be symptomatic. Serum sortilin concentrations were measured using the enzyme-linked immunosorbent assay. RESULTS: Serum sortilin level was significantly higher in the symptomatic group than in the severe asymptomatic group (1.53 ± 0.25 ng/mL vs 1.34 ± 0.19 ng/mL, p < 0.001). Besides, high serum sortilin levels (odds ratio = 4.91, 95% confidence intervals 1.24-19.51, p = 0.023) were identified as independent predictors of symptomatic carotid plaque. In the receiver operating characteristic curve analysis, serum sortilin levels higher than 1.34 ng/mL predicted stroke/TIA with a sensitivity of 66.3% and a specificity of 67% (AUC = 0.725, p < 0.001). CONCLUSIONS: Serum sortilin level is increased in the presence of symptomatic intermediate CAS and may have clinical value in the management of patients with carotid artery disease.

Left Atrial Dysfunction as Marker of Arrhythmic Events in Patients with Hypertrophic Cardiomyopathy.

BACKGROUND: In this study, we investigated whether left atrial functions evaluated by speckle tracking echocardiography , classic echocardiographic and clinic parameters predict appropriate Implantable Cardioverter Defibrillator (ICD) shock in patients who underwent ICD implantation for hypertrophic cardiomyopathy. METHODS: Totally 87 patients who received ICD implantation for primary or secondary prevention were included in the study. Patients' clinical, electrocardiographic, 2 dimen- sion classic, and speckle tracking echocardiographic data were collected. Left atrial functions were assessed by speckle tracking echocardiography. Left atrial strain just before mitral valve opening was taken as peak atrial longitudinal strain. Appropriate ICD therapy was defined as cardioversion or defibrillation due to ventricular tachycardia or fibrillation. Patients were divided into 2 groups as occurrence or absence of appropri- ate ICD therapy during follow-up (mean, 50.2 ± 9.3 months). Patients with an European Society of Cardiology (ESC) risk score >6% were considered high-risk patients. RESULTS: A total of 24 (27.5 %) patients were observed to have an appropriate ICD therapy. In patients on whom appropriate ICD therapy was performed, a higher Sudden Cardiac Death risk Score and decreased peak atrial longitudinal strain and global longitudinal peak strain were observed. In patients with high ESC risk score (> 6%), in Cox regres- sion analysis, peak atrial longitudinal strain (odds ratio: 0.806, P = .008), Sudden Cardiac Death risk score (odds ratio: 1.114, P = .03) and global longitudinal peak strain (odds ratio: 1.263, P = .02) were found to be independent predictors of occurrence of appropriate ICD therapy. CONCLUSION: Easily measurable peak atrial longitudinal strain may provide additional information in predicting ventricular arrhythmias or deciding on prophylactic medical treatment to prevent ventricular arrhythmias or reduce the frequency of appropriate shock in high-risk patients with ICD implanted.

Clinical Utility of Left Atrial Asynchrony and Mechanical Function in Patients with Hypertrophic Cardiomyopathy.

Background: The aim of this study was to examine whether left atrial dispersion and left atrial strain as measured by speckle tracking echocardiography and clinical parameters are predictors of the development of atrial fibrillation in patients with hypertrophic cardiomyopathy. Methods: A total of 151 patients (69% male, mean age 48.9 ± 14.2 years) with hypertrophic cardiomyopathy were included in the study. The patients' demographic, clinical, electrocardiographic, 2-dimensional classic and speckle tracking echocardiographic data were collected. Atrial fibrillation was identified by 12-lead electrocardiograms or 24-72 hours of Holter recordings during the follow-up period. Atrial dispersion was defined as the standard deviation of time to peak strain in 12 left atrial segments. Results: During the follow-up period, 40 patients (26%) developed atrial fibrillation. Peak atrial longitudinal strain (16.8 ± 6 vs. 22.1 ± 6.6, p ≤ 0.001) was significantly lower in the patients who developed atrial fibrillation than in those who did not. However, atrial dispersion was significantly higher in the group which developed atrial fibrillation (61 [46.7,78.6] vs. 41.3 [30.6-51], p ≤ 0.001). In multivariate Cox regression analysis, atrial dispersion (msn) (hazard ratio: 1.019, 95% confidence interval: 1.004-1.033, p = 0.01), peak atrial longitudinal strain, and age were found to be independent predictors of atrial fibrillation. Conclusions: In patients with hypertrophic cardiomyopathy, atrial dispersion, peak atrial longitudinal strain and age are predictive of the development of atrial fibrillation. Atrial dispersion measured by a speckle tracking-based method may provide further information on left atrial function in patients with hypertrophic cardiomyopathy or other disease states.

Inter-arm blood pressure difference is associated with contrast-induced nephropathy in patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention.

OBJECTIVE: Contrast-induced nephropathy (CIN) is a serious complication in patients with ST segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (p-PCI). An interarm systolic blood pressure difference (IASBD) ≥10 mmHg has been identified as an independent risk factor for cardiovascular disease and mortality. The aim of this study was to evaluate the predictive value of the IASBD for the risk of CIN in patients with STEMI who underwent p-PCI. METHOD: We prospectively investigated 2120 consecutive patients who were hospitalized with a diagnosis of STEMI and underwent p-PCI. A relative increase in serum creatinine levels of ≥ 25% or an absolute increase of ≥ 0.5 mg/dL from baseline within 72 h of contrast exposure was defined as CIN. The IASBD was calculated on admission to the emergency department. The risk of CIN was evaluated. RESULTS: The incidence of CIN was 6.6% (n = 139). The patients were divided into 2 groups based on the development of CIN. Age (p = .001), baseline creatinine levels (p < .001), DM (p < .001), HT (p < .001) and anemia (p = .001) were higher in patients with CIN. An IASBD ≥10 mmHg was noted in 13 (9.3%) patients in the CIN group and 83 (4.1%) (p = .001) in the non-CIN group (Table 1). According to the multivariate analysis, the IASBD was found to be a predictor of CIN development (OR: 2.36, 95% CI: 1.42-3.90, p: 0.001). CONCLUSION: The IASBD on admission can be a potential predictor of CIN development in patients with STEMI who underwent p-PCI.

Myocardial early systolic lengthening predicts mid-term outcomes in patients with hypertrophic cardiomyopathy.

In this study, we investigated whether early systolic lengthening (ESL) which reflects subclinical ischemia and other echocardiographic and clinic parameters predict primary outcome [appropriate ICD shock, cardiovascular mortality and ventricular tachycardia (VT) or fibrillation] in patients with hypertrophic cardiomyopathy (HCM). 202 Patients with HCM (68% male, mean age 48 ± 13.9 years) were included in the study. Patients' clinical, electrocardiographic, 2D classic and speckle tracking echocardiography (STE) data were collected. ESL was defined as time from onset of the Q wave on ECG (onset of the R wave if the Q wave was absent) to maximum myocardial systolic lengthening. Patients were divided into two groups as occurrence or absence of primary outcome during 5 years follow up. During the follow-up period of 5 years (mean follow-up duration, 45.9 ± 10.8 months), 31 patients (15%) developed primary outcome [appropriate ICD shock 22 (11%), cardiovascular death 6 (3%), VT/VF 3(1.5%)]. Higher HCM Risk SCD score, longer ESL, and decreased global longitudinal peak strain (GLPS) were observed in patients with primary outcome. A Cox regression analysis, ESL, GLPS and HCM Risk SCD score were found to be independent predictors of occurrence of primary outcome. In ROC curve analysis, ESL > 53.5 msn could discriminate between groups with and without a primary outcome (AUC 0.768, 80% sensitivity and 60% specificity, CI 95% 0.666-0.871). ESL were found to be predictive for primary outcome in patients with HCM. Readily measurable ESL could be helpful to distinguish patients at high risk who could optimally benefit from ICD therapy.

Kounis Syndrome: Dexketoprofen-Associated ST-Elevation Myocardial Infarction.

Allergic angina and allergic myocardial infarction are common diseases associated with acute coronary syndromes and encompass a wide spectrum of mast cell activation disorders termed "Kounis Syndrome". We present here a patient with Kounis syndrome presenting with sudden cardiac arrest after intravenous infusion of dexketoprofen in the emergency room. LEARNING POINTS: There are 3 types of Kounis syndrome, of which Type I, allergic coronary vasospasm, is the most common.The most common presentation of Kounis syndrome is ST-elevation myocardial infarction.Although not all cases of Kounis syndrome are reported, they are common in clinical practice and many more causal factors are predicted to play a role in the future.

The Role of the Left Atrial Strain Parameters on Grading of Aortic Regurgitation.

BACKGROUND: Grading the severity of aortic regurgitation (AR) is very important for clinical follow-up. In AR, left atrial (LA) mechanics can be affected in time and LA strain variations can be illuminating for the grading of AR. The purpose of this study is to determine whether the LA strain parameters are associated with the severity of AR or not. METHODOLOGY: Sixty-four consecutive patients with AR were included in this study. Patients divided into three groups as mild (n: 22), moderate (n: 15), or severe (n: 27). All patients' LA strain measurements were performed and results were compared between groups. RESULTS: Between the groups, LA reservoir (LA-Res) in the mild, moderate, and severe AR groups was 42.0 ± 18.0, 41.4 ± 14.8, and 29.2 ± 6.0, respectively (P: 0.002) and LA pump in the mild, moderate, and severe AR groups was 21.2 ± 8.7, 19.3 ± 7.4, and 13.1 ± 4.4, respectively (P < 0.001), different, while no difference was noticed on LA SRs, LA SRe, and LA SRa. CONCLUSION: This study showed that LA-Res and LA pump parameters of the patients with severe AR significantly decreased compared to those of the mild and moderate AR group. The grading of the LA mechanics in patients with chronic AR might provide a supplementary contribution to the present parameters in the grading of AR.

Correlation between serum sortilin levels and severity of extracranial carotid artery stenosis.

OBJECTIVE: Atherosclerosis is a chronic inflammatory vascular condition characterised by intimal thickening with cholesterol accumulation and macrophage foam cell infiltration causing plaque formation at the site of the injured vessel wall. This condition is a major contributor to carotid artery stenosis (CAS). Sortilin, a member of the mammalian vacuolar protein sorting 10 protein family, promotes uptake of low-density lipoprotein particles into macrophages with consequent foam cell formation independent of the low-density lipoprotein receptor, and thereby, accelerates atherosclerotic plaque formation and progression. We investigated the correlation between serum sortilin levels and the severity of extracranial CAS. MATERIALS AND METHODS: The study included 149 patients who underwent carotid angiography for suspected carotid artery disease. The North American Symptomatic Carotid Endarterectomy Trial 2011 criteria were used to determine the degree of CAS. Serum sortilin concentrations were measured using the enzyme-linked immunosorbent assay. RESULTS: Serum sortilin levels were significantly higher in the severe CAS than in the non-severe CAS group (2.71 ± 0.71 ng/mL vs 1.63 ± 0.57 ng/mL, P < .001). Receiver operating characteristic curve analysis showed that serum sortilin levels >1.66 ng/mL predicted severe CAS with sensitivity of 83.49% and specificity of 56.76%. CONCLUSION: Current data suggest that prediction of severe CAS may serve as an atherosclerosis biomarker and significantly contribute to research on disease progression in atherosclerosis, as well as in other arterial diseases. Sortilin may be a potential therapeutic target owing to its role in the pathogenesis of atherosclerotic carotid artery disease.

Primary patency and amputation free survival after endovascular management of infrarenal aorta total occlusions.

OBJECTIVE: Endovascular therapy (EVT) has increasingly been used even after the development of new techniques and technologies. EVT has displayed durable early and mid-term outcomes for infrarenal aorta occlusions (IAO). Nonetheless, little is known regarding their long-term outcomes and predictors of restenosis. METHODS: A total of 55 consecutive patients (age, 58.8±6.97 years; 67.2% male; 42% critical limb ischemia) from a single-center database, undergoing EVT for IAO disease between January 2011 and March 2019 were retrospectively analyzed. The outcome measures were primary patency rate and amputation free survival calculated by the Kaplan-Meier method. Independent predictors of restenosis were assessed by Cox proportional hazard regression model. RESULTS: In 49 patients (89.1%), technical success was achieved. In total, 190 stents (65 self-expandable stents, 60 balloon-expandable stents) were implanted. During the follow up of 34.5±28 months, 7 patients experienced loss of patency. Primary patency rates were 96%, 82%, and 75% at 1, 3, and 5 years, respectively, and amputation free survival rates were 100%, 90%, and 82% at 1, 3, and 5 years, respectively. CONCLUSION: In this study, five-year outcomes of primary patency and amputation free survival for EVT of infrarenal aorta total occlusive lesions were favorable. None of the demographic, lesion, and device factors were independently associated with loss of primary patency.

Treatment with covered stent of giant femoral artery aneurysm causing deep vein thrombosis.

Femoral artery aneurysm (FAA) is a rare peripheral vascular aneurysm that can lead to thrombosis, embolism and fatal rupture in untreated cases. The clinical presentation of FAA varies from the finding of an asymptomatic mass on routine physical examination to acutelimb-threatening ischemia. Presently, a case of FAA that caused deep vein thrombosis and compartment syndrome has been described. Although the current treatment method recommended for FAA is an open surgical procedure, in this case, an endovascular intervention was performed due to high risk of surgical mortality.

Rationale, design, and methodology of the EPIC (Epidemiology of Polypharmacy and Potential Drug-Drug Interactions in Elderly Cardiac Outpatients) study.

OBJECTIVE: The aim of this study is to assess the prevalence of polypharmacy, inappropriate drug use, and drug-drug interactions (DDIs) in elderly patients presenting at outpatient cardiology clinics in Turkey. METHODS: The EPIC (Epidemiology of Polypharmacy and Potential Drug-Drug Interactions in Elderly Cardiac Outpatients) study will be an observational, real-world, multicenter study conducted to evaluate DDIs and polypharmacy in elderly cardiac outpatients. All consecutive patients (aged ≥65 years) admitted to outpatient cardiology clinics between July 30, 2018 and July 30, 2019 who provide written, informed consent will be enrolled. A total of approximately 5000 patients are to be enrolled in this non-interventional study. All of the data will be collected at one point in time and current clinical practice will be evaluated (ClinicalTrials.gov NCT03370523). RESULTS: Patient demographics, comorbid disease characteristics, laboratory test results, and details of medication use will be collected using self-reports and medical records. The severity of comorbid disease will be recorded and scored according to Charlson Comorbidity Index (CCI) and patients will be divided into 3 groups: mild, those with a CCI score of 1-2; moderate, those with a CCI score of 3-4; and severe, those with a CCI score of ≥5. Polypharmacy will be defined as the use of 5 or more medications at one time. DDIs will be determined using the Lexicomp Online drug interaction screening tool and potentially inappropriate medications will be defined based on the 2015 update of the Beers Criteria for Potentially Inappropriate Medication Use in Older Adults. Severe drug interactions will be defined as those in category D or X. CONCLUSION: EPIC will be the first large-scale study in Turkey to evaluate polypharmacy, potentially inappropriate medications, and DDIs in elderly cardiac outpatients in a real-world clinical setting.

Utility of speckle tracking echocardiography imaging in patients with asymptomatic and symptomatic arrhythmogenic right ventricular cardiomyopathy.

BACKGROUND: Arrhythmogenic right ventricular dysplasia (ARVD) is characterized by the progressive replacement of ventricular myocytes with variable amounts of fibrous and adipose tissue. Several studies have suggested that speckle tracking echocardiographic (STE) parameters such as strain (S) and strain rate (SR) may prove useful in the early detection of right ventricular (RV) dysfunction. Therefore, the aim of this study was to evaluate RV myocardial function using the STE method in both asymptomatic and symptomatic patients with ARVD and to assess its potential role in the differential diagnosis of these two presentations. METHODS: We recruited 34 patients with ARVD. Seventeen patients were symptomatic, and seventeen were asymptomatic. RESULTS: The RV free wall global longitudinal S and SR were significantly lower in symptomatic patients with ARVD than in asymptomatic patients. According to a cutoff value of 1.35 per seconds for RV global SR, the sensitivity and specificity for predicting ARVD were 88% and 77%, respectively. According to a cutoff value of 17.3% for RV S, the sensitivity and specificity for predicting ARVD were 82% and 77%, respectively. CONCLUSION: In conclusion, we present strong evidence that STE-derived global S and SR in the RV free wall are decreased in symptomatic patients with ARVD compared with asymptomatic patients.

Platelet/lymphocyte ratio was associated with impaired myocardial perfusion and both in-hospital and long-term adverse outcome in patients with ST-segment elevation acute myocardial infarction undergoing primary coronary intervention.

INTRODUCTION: Platelet/lymphocyte ratio (PLR) has been shown to be an inflammatory and thrombotic biomarker for coronary heart disease, but its prognostic value in ST-segment elevation myocardial infarction (STEMI) has not been fully investigated. AIM: To investigate the relationship between PLR and no-reflow, along with the in-hospital and long-term outcomes in patients with STEMI. MATERIAL AND METHODS: In the present study, we included 304 consecutive patients suffering from STEMI who underwent primary percutaneous coronary intervention (p-PCI). Patients were stratified according to PLR tertiles based on the blood samples obtained in the emergency room upon admission. No-reflow after p-PCI was defined as a coronary thrombolysis in myocardial infarction (TIMI) flow grade ≤ 2 after vessel recanalization, or TIMI flow grade 3 together with a final myocardial blush grade (MBG) < 2. RESULTS: The mean follow-up period was 24 months (range: 22-26 months). The number of patients characterized with no-reflow was counted to depict increments throughout successive PLR tertiles (14% vs. 20% vs. 45%, p < 0.001). In-hospital major adverse cardiovascular events and death increased as the PLR increased (p < 0.001, p < 0.001). Long-term MACE and death also increased as the PLR increased (p < 0.001, p < 0.001). Multivariable logistic regression analysis revealed that PLR remained an independent predictor for both in-hospital (OR = 1.01, 95% CI: 1.00-1.01; p = 0.002) and major long-term (OR = 1.01, 95% CI: 1.00-1.01; p < 0.001) adverse cardiac events. CONCLUSIONS: Platelet/lymphocyte ratio on admission is a strong and independent predictor of both the no-reflow phenomenon and long-term prognosis following p-PCI in patients with STEMI.

False Lumen Catheterization in a Patient Who Has Type A Aortic Dissection That Mimics Acute Inferior Myocardial Infarction: A Case Report.

We report a 61-year-old patient who suffered from a type A aortic dissection that mimicked an acute inferior myocardial infarction. During a routine cardiac catheterization procedure, diagnostic catheters can be inserted accidentally into the false lumen. Invasive cardiologists should keep this complication in mind.

The Effect of Chronic Anabolic-Androgenic Steroid Use on Tp-E Interval, Tp-E/Qt Ratio, and Tp-E/Qtc Ratio in Male Bodybuilders.

BACKGROUND: The chronic consumption of androgenic anabolic steroids has shown to cause atrial arrhythmias. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. The aim of this study was to evaluate repolarization dispersion measured from the 12-lead surface electrocardiogram (including Tp-e interval, Tp-e/QT ratio, and Tp-e/cQT ratio) in bodybuilders who are using anabolic androgenic steroids (AAS). METHODS: We selected a population of 33 competitive bodybuilders, including 15 actively using AAS for ≥ 2 years (users) and 18 who had never used AAS (nonusers), all men. RESULTS: QT, cQT, QTd, cQTd, JT, and cJT were significantly increased in AAS users bodybulders compared to the nonusers (all P < 0.001). Tp-e interval, Tp-e/QT ratio, and Tp-e/cQT ratio were also significantly higher in AAS user group compared to the nonuser group (all P < 0.001). QRS duration was not different between the groups. There were negative correlation between E(m) and Tp-e, Tp-e/QT ratio, Tp-e/cQT ration (r = -0.657, P < 0.01; r = -0.607, P = 0.02; r = -0.583, P = 0.02; respectively).There were also negative correlation between S(m) and Tp-e, Tp-e/QT ratio, Tp-e/cQT ration (r = -0.681, P < 0.01; r = -0.549, P = 0.03; r = -0.544, P = 0.023; respectively). CONCLUSION: In conclusion, we have presented a strong evidence suggesting that Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio were increased in AAS users, which suggest that there might be a link between AAS use and ventricular arrthymias and sudden death.

Right heart free-floating thrombus in a pregnant woman with massive pulmonary embolism: a case of 'emboli in transit'.

The mainstay of treatment for massive pulmonary embolism in nonpregnant individuals is urgent thrombolytic therapy, but experience with these drugs in pregnancy is limited. We report a case of a 36-year-old woman at 27 weeks' gestation who was admitted with a massive, life-threatening pulmonary embolism. The diagnosis was rapidly accomplished in the coronary care unit by transthoracic echocardiography that showed signs of pulmonary hypertension as well as a large, free-floating thrombus in the right heart. As she was hemodynamically unstable, we started treatment with tissue plasminogen activator resulting in complete resolution of cardiorespiratory symptoms. A live baby was delivered by Caesarean section at 37 weeks of gestation, and no complications were seen during the 1-year follow-up. The present case report emphasizes the pivotal role of repeat echocardiography in clinical decision-making and the life-saving potential of thrombolytic therapy without serious adverse effects.

Long-term anabolic androgenic steroid use is associated with increased atrial electromechanical delay in male bodybuilders.

We investigated the effect of long-term supraphysiologic doses of anabolic androgenic steroids (AAS) on atrial electromechanical delay (AEMD) in male bodybuilders. We clearly demonstrated that long-term consumption of supraphysiologic doses of AAS is associated with higher values of inter- and intra-AEMD in healthy young bodybuilders.
