Item Effects of Continuous-Flow Left Ventricular Assist Device Therapy on Peripheral Vascular Function(2022) Kaya, Ersin; Kocabas, Umut; Simsek, Evrim; Nalbantgil, Sanem; Kahraman, Umit; Engin, Cagatay; Yagdi, Tahir; Ozbaran, Mustafa; Akilli, Azem; 35089263; GXG-7709-2022The peripheral vascular effects of continuous-flow left ventricular assist device (CF-LVAD) implantation are still unclear. The aim of the current study was to determine peripheral vascular function before and after implantation of CF-LVAD in patients with end-stage heart failure (HF), and to compare this data to age- and sex-matched chronic heart failure with reduced ejection fraction (HFrEF) patients. Forty-three consecutive end-stage HF patients (New York Heart Association [NYHA] class III/IV; three women and 40 men; mean age 53 +/- 11 years) who planned to receive CF-LVAD implantation comprised the LVAD patient population, and their clinical characteristics, preoperative and third postoperative month peripheral vascular function assessment data including flow-mediated dilation (FMD) and pulsatility index (PI) assessed by ultrasound Doppler in brachial artery were compared to age- and sex-matched chronic, stable HFrEF patients (NYHA class II; five women and 30 men; mean age 51 +/- 10 years). After CF-LVAD implantation, median FMD decreased from 5.4 to 3.7% (p < 0.001), and median PI decreased from 6.9 to 1.4 (p < 0.001). In patients with end-stage HF before CF-LVAD implantation, FMD and PI were significantly lower compared to the chronic HFrEF patients (FMD: 5.4% +/- 0.9% vs. 7.6% +/- 1.1%; p < 0.001, respectively) and (PI: 6.9 +/- 1.3 vs. 7.4 +/- 1.2; p = 0.023, respectively). The current study revealed impaired peripheral vascular function in the end-stage HF patients compared to stable HFrEF patients, and documented the deterioration of peripheral vascular function after CF-LVAD implantation. These results suggest that impaired peripheral vascular function in the CF-LVAD patients compared to preoperative assessment is a consequence of the nonpulsatile blood flow due to the continuous-flow mechanical support.Item Resting Heart Rate and Real-Life Treatment Modalities in Outpatients with Left Ventricular Systolic Dysfunction Study: A Multicenter, Prospective, Observational, and National Registry(2021) Cavusoglu, Yuksel; Kozan, Omer; Temizhan, Ahmet; Kucukoglu, Mehmet Serdar; 33960305; ABC-9349-2021Objective: Heart rate (HR) reduction is associated with improved outcomes in heart failure (HF). This multicenter, prospective, observational, and national registry aimed to evaluate resting HR and the impacts of HR-related medications in real-life clinical practice in patients with HF. Methods: The Resting HR and Real-Life Treatment Modalities in Outpatients with Left Ventricular Systolic Dysfunction (REALITY HF) study enrolled 1054 patients with HF and left ventricular ejection fraction (LVEF) of <40% from 16 centers. Clinical characteristics, HR, and medications were noted (enrollment phase). A total of 487 patients with sinus rhythm and HR of >= 70 bpm were included in a further 4-month follow-up (FU) program (V0). Changes in HR and medications were reevaluated at 1-month (V1) and 4-month (V2) FU visits. The Kansas City Cardiomyopathy Questionnaire (KCCQ) was used to assess the quality of life (QoL) of 320 patients in a 4-month FU program. Results: During enrollment, 794 patients (75.3%) were in sinus rhythm, in whom resting HR was 76.7 +/- 14 bpm, 69.1% had a resting HR of >= 70 bpm, 79.1% were receiving beta blocker (BB), and 6.1% were receiving ivabradine. Resting HR was lower in patients receiving BB (75.8 +/- 13 vs. 80.4 +/- 16 bpm; p=0.001); however, 65.8% of those still had a resting HR of >= 70 bpm. A significant association was found between elevated HR and worse New York Heart Association (NYHA) class, worse QoL, or lower LVEF. During the 4-month FU, adjustment of HR-lowering therapy was left to the physician's discretion. Resting HR significantly reduced from 83.6 +/- 12 (80) bpm at V0 to 78.6 +/- 13 (77) bpm at V1 (p=0.001) and further decreased to 73.0 +/- 11 (73) bpm at V2 (p=0.001). Patients achieving a resting HR of >= 70 bpm were 21.7% at V1 (p=0.001) and 39.9% at V2 (p=0.001). KCCQ significantly increased from 59.7 +/- 23 (62.7) at V0 to 73.1 +/- 18 (78.5) at V2 (p=0.001). In addition, patients with NYHA I increased from 22.2% at V0 to 29.2% at V1 and 39.4% at V2 (p=0.01). Conclusion: In real-life clinical practice, elevated HR is highly prevalent in HF despite widely used BB therapy and is associated with worse clinical picture. Therapeutic interventions targeting HR significantly reduce HR, and HR lowering is associated with improved clinical outcomes.Item Left atrial strain is a predictor of left ventricular systolic and diastolic reverse remodelling in CRT candidates(2021) Galli, Elena; Oger, Emmanuel; Aalen, John M.; Duchenne, Jurgen; Larsen, Camilla K.; Sade, Elif; Hubert, Arnaud; Gallard, Aban; Penicka, Martin; Linde, Cecilia; Le Rolle, Virginie; Hernandez, Alfredo; Leclercq, Christophe; Voig, Jens-Uwe; Smiseth, Otto A.; Donal, Erwan; 34432006Aims The left atrium (LA) has a pivotal role in cardiac performance and LA deformation is a well-known prognostic predictor in several clinical conditions including heart failure with reduced ejection fraction. The aim of this study is to investigate the effect of cardiac resynchronization therapy (CRT) on both LA morphology and function and to assess the impact of LA reservoir strain (LARS) on left ventricular (LV) systolic and diastolic remodelling after CRT. Methods and results Two hundred and twenty-one CRT-candidates were prospectively included in the study in four tertiary centres and underwent echocardiography before CRT-implantation and at 6-month follow-up (FU). CRT-response was defined by a 15% reduction in LV end-systolic volume. LV systolic and diastolic remodelling were defined as the percent reduction in LV end-systolic and end-diastolic volume at FU. Indexed LA volume (LAVI) and LV-global longitudinal (GLS) strain were the main parameters correlated with LARS, with LV-GLS being the strongest determinant of LARS (r = -0.59, P < 0.0001). CRT induced a significant improvement in LAVI and LARS in responders (both P < 0.0001). LARS was an independent predictor of both LV systolic and diastolic remodelling at follow-up (r = -0.14, P = 0.049 and r = -0.17, P = 0.002, respectively). Conclusion CRT induces a significant improvement in LAVI and LARS in responders. In CRT candidates, the evaluation of LARS before CRT delivery is an independent predictor of LV systolic and diastolic remodelling at FU.Item Snapshot evaluation of acute and chronic heart failure in real-life in Turkey: A follow-up data for mortality(2020) Yilmaz, Mehmet Birhan; Aksakal, Emrah; Aksu, Ugur; Altay, Hakan; Nesligul, Yildirim; Celik, Ahmet; Akil, Mehmet Ata; Bekar, Lutfu; Vural, Mustafa Gokhan; Guvenc, Rengin Cetin; Ozer, Savas; Ural, Dilek; Cavusoglu, Yuksel; Tokgozoglu, Lale; 32120368; AAE-1392-2021Objective: Heart failure (HF) is a progressive clinical syndrome. SELFIE-TR is a registry illustrating the overall HF patient profile of Turkey. Herein, all-cause mortality (ACM) data during follow-up were provided. Methods: This is a prospective outcome analysis of SELFIE-TR. Patients were classified as acute HF (AHF) versus chronic HF (CHF) and HF with reduced ejection fraction (HFrEF), HF with mid-range ejection fraction, and HF with preserved ejection fraction and were followed up for ACM. Results: There were 1054 patients with a mean age of 63.3 +/- 13.3 years and with a median follow-up period of 16 (7-17) months. Survival data within 1 year were available in 1022 patients. Crude ACM was 19.9% for 1 year in the whole group. ACM within 1 year was 13.7% versus 32.6% in patients with CHF and AHF, respectively (p<0.001). Angiotensin-converting enzyme inhibitor/angiotensin receptor blocker, beta blocker, and mineralocorticoid receptor antagonist were present in 70.6%, 88.2%, and 50.7%, respectively. In the whole cohort, survival curves were graded according to guideline-directed medical therapy (GDMT) scores <= 1 versus 2 versus 3 as 28% versus 20.2% versus 12.2%, respectively (p<0.001). Multivariate analysis of the whole cohort yielded age (p=0.009) and AHF (p=0.028) as independent predictors of mortality in 1 year. Conclusion: One-year mortality is high in Turkish patients with HF compared with contemporary cohorts with AHF and CHF. Of note, GDMT score is influential on 1-year mortality being the most striking one on chronic HFrEF. On the other hand, in the whole cohort, age and AHF were the only independent predictors of death in 1 year.Item Sodium glucose co-transporter 2 inhibitors in heart failure therapy(2020) Cavusoglu, Yuksel; Altay, Hakan; Cahn, Avivit; Celik, Ahmet; Demir, Serafettin; Kilicaslan, Baris; Nalbantgil, Sanem; Raz, Itamar; Temizhan, Ahmet; Yildirimturk, Ozlem; Yilmaz, Mehmet Birhan; AAE-1392-2021; 32281958Sodium-glucose cotransporter-2 inhibitors (SGLT-2i) are a new class of drugs for patients with type 2 diabetes (T2DM) which inhibit urinary glucose reabsorption in the proximal tubule of the nephron and result in glucosuria, natriuresis and diuresis. In large, randomized clinical trials, SGLT-2i have been shown to reduce major cardiovascular (CV) events and heart failure (HF) hospitalizations in patients with T2DM who have atherosclerotic CV disease or CV risk factors. In these trials, SGLT-2i is have their greatest and most consistent effect on reducing the risk of HF hospitalization. The reduction in HF hospitalization was also observed in subgroups of patients with a HF diagnosis at baseline, which raised the possibility of a clinical benefit of SGLT-2i in HF patients, regardless of the presence or absence of T2DM. In very recently published DAPA-HF trial, a SGLT-2i, dapagliflozin treatment on top of standard HF therapy has been shown to have clear clinical benefits in terms of reducing HF hospitalization, CV mortality, all-cause mortality and improving quality of life in HF patients. This compelling evidence suggests that SGLT-2i have a potential to be an effective treatment option in HF, regardless of diabetes. This article provides a comprehensive overview focused on the role of SGLT-2i in the treatment of HF.Item Clinical characteristics and in-hospital outcomes of acute decompensated heart failure patients with and without atrial fibrillation(2020) Kocabas, Umut; Sinan, Umit Yasar; Arugaslan, Emre; Kursun, Mustafa; Coner, Ali; Celebi, Ozlem Ozcan; Ozturk, Cengiz; Dalgic, Onur; Turkoglu, Ebru Ipek; Kemal, Hatice Soner; Gazi, Emine; Altin, Cihan; Zoghi, Mehdi; 32352420Objective: Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular diseases. The impact of AF on in-hospital outcomes in acute decompensated heart failure (ADHF) is controversial. The aim of this study is to determine the prevalence of AF among hospitalized patients with ADHF and describe the clinical characteristics and in-hospital outcomes of these patients with and without AF. Methods: We examined the multicenter, observational data from the real-life data of hospitalized patients with HF: Journey HF-TR study in Turkey that studied the clinical characteristics and in-hospital outcomes of hospitalized patients with ADHF between September 2015 and September 2016. Results: Of the 1,606 patients hospitalized with ADHF, 626 (39%) had a history of AF or developed new-onset AF during hospitalization. The patients with AF were older (71 +/- 12 vs. 65 +/- 13 years; p<0.001) and more likely to have a history of hypertension, valvular heart disease, and stroke. The AF patients were less likely to have coronary artery disease and diabetes. In-hospital adverse event rates and length of in-hospital stay were similar in ADHF patients, both with and without AF. In-hospital all-cause mortality rate was higher in patients with AF than in patients without AF, although the difference was not statistically significant (8.9% vs. 6.8%; p=0.121). Conclusion: AF has been found in more than one-third of the patients hospitalized with ADHF, and it has varied clinical features and comorbidities. The presence of AF is not associated with increased adverse events or all-cause mortality during the hospitalization time.Item EuroEcho 2019: highlights(2020) Magne, Julien; Bharucha, Tara; Cikes, Maya; Galderisi, Maurizio; Price, Suzanna; Sade, Leyla Elif; Popescu, Bogdan A.; Cosyns, Bernard; Edvardsen, Thor; 32182333The annual meeting of the European Association of Cardiovascular Imaging, EuroEcho 2019, was held in Vienna, Austria, in December 2019. In this article, we present a summary of the 'Highlights' session.Item Increased frequency of occurrence of bendopnea is associated with poor outcomes in heart failure outpatients(2020) Kaya, Hakki; Sahin, Anil; Gunes, Hakan; Bekar, Lutfu; Celik, Ahmet; Cavusoglu, Yuksel; Caldir, Vedat; Gungor, Hasan; Yilmaz, Mehmet Birhan; 32812491Background Relationship between the frequency of occurrence of bendopnea during the daily life of heart failure (HF) outpatients and clinical outcomes has never been evaluated before. Methods Turkish Research Team-Heart Failure (TREAT-HF) is a network between HF centres, which undertakes multicentric observational studies in HF. Herein, the data including stable 573 HF patients with reduced ejection fraction out of seven HF centres were presented. A questionnaire was filled by the patients, with the question 'Do you experience shortness of breath while tying your shoelace?', assessing the presence and frequency of bendopnea. Results To the question related to bendopnea, 48% of the patients answered 'yes, every time', 31% answered 'yes, sometimes', and 21% answered 'No'. Patients were followed for an average of 24 +/- 14 months, and the patients who answered 'yes, every time' and 'yes, sometimes' to the bendopnea question were found having increased risk for both HF-related hospitalisations (HR:3.2,p < .001- HR:2.8,p = .005) and composite outcome consisting of 'HF-related hospitalisations and all-cause death in the multi-variate analysis (HR:3.1,p < .001- HR:3.0,p < .001). Kaplan Meier analysis for HF-related hospitalisation, all-cause death, and the composite of these were provided for these three groups, yielding significant and graded divergence curves with the best prognosis in 'no' group, with the moderate prognosis in 'sometimes' group, and with the worst prognosis in the 'every time' group. Conclusion For the first time in the literature, our study shows that the increased frequency of bendopnea occurrence in daily life is associated with poor outcomes in HF outpatients.Item Role ofPoint-of-CareLung and Inferior Vena Cava Ultrasound in Clinical Decisions for Patients Presenting to the Emergency Department With Symptoms of Acute Decompensated Heart Failure(2020) Hacialiogullari, Fakiye; Yilmaz, Fevzi; Yilmaz, Aykut; Sonmez, Bedriye Muge; Demir, Tayfun Anil; Karadas, Mehmet Akif; Duyan, Murat; Ayaz, Gizem; Ozdemir, Metin; 0000-0001-5841-2591; 0000-0002-4719-2535; 32865243; AAJ-3607-2021; AAJ-1600-2021Objectives This prospective study was performed to evaluate the diagnostic role of point-of-care lung ultrasound (LUS) and inferior vena cava (IVC) ultrasound in patients with acute decompensated heart failure (ADHF). Methods A prospective cohort study was conducted between January 2018 and November 2018 on patients with a diagnosis of ADHF in the emergency department (ED). On admission, LUS findings, inspiratory and expiratory IVC diameters, and the inferior vena cava collapsibility index (IVCCI) were obtained. After therapeutic interventions, third-hour changes in LUS and the IVC index and the treatment response were assessed. Results Eighty patients were enrolled. Forty-six (58%) patients had an ejection fraction (EF) greater than 40%, and 34 (42%) had an EF of less than 40%. Significant differences were detected between the admission and third-hour inspiratory IVC diameter, expiratory IVC diameter, and IVCCI (P= .001). There was no correlation between the EF and inspiratory IVC diameter (r= -0.03;P= .976), expiratory IVC diameter (r= -109;P= .336), or IVCCI (r= -0.72;P= .523) and between the B-type natriuretic peptide level and inspiratory IVC diameter (r= -0.58;P= .610), expiratory IVC diameter (r= -0.33;P= .774), or IVCCI (r= -0.78;P= .493) either. A comparison of admission and third-hour numbers of B-lines on LUS imaging showed a significant decrease in the number of B-lines in all zones at the end of 3 hours (P= .001). A significant difference existed between the hospitalized and discharged patients with respect to IVC diameters and number of B-lines. Conclusions In the ED setting, an assessment of B-lines and measurement of IVC diameters are better markers than the B-type natriuretic peptide level, EF, or chest x-ray for diagnosis of ADHF and can be used to make decisions for hospitalization or discharge from the ED.Item The year 2019 in the European Heart Journal - Cardiovascular Imaging: part II(2020) Cosyns, Bernard; Haugaa, Kristina H.; Gerber, Bernrhard; Gimelli, Alessia; Sade, Leyla Elif; Maurer, Gerald; Popescu, Bogdan A.; Edvardsen, Thor; 33188688The European Heart Journal - Cardiovascular Imaging was Launched in 2012 and has during these years become one of the leading multimodality cardiovascular imaging journal.
