Item Cost-of-disease of Heart Failure in Turkey: A Delphi Panel-based Analysis of Direct and Indirect Costs(2022) Cavusoglu, Yuksel; Altay, Hakan; Aras, Dursun; Celik, Ahmet; Ertas, Fatih Sinan; Kilicaslan, Baris; Nalbantgil, Sanem; Temizhan, Ahmet; Ural, Dilek; Yildirimturk, Ozlem; Yilmaz, Mehmet Birhan; 35872647Background: Heart failure (HF) is considered a significant public health issue with a substantial and growing epidemiologic and economic burden in relation to longer life expectancy and aging global population Aims: To determine cost-of-disease of heart failure (HF) in Turkey from the payer perspective. Study Design: Cross-sectional cost of disease study. Methods: In this cost-of-disease study, annual direct and indirect costs of management of HF were determined based on epidemiological, clinical and lost productivity inputs provided by a Delphi panel consisted of 11 experts in HF with respect to ejection fraction (EF) status (HF patients with reduced EF (HFrEF), mid-range EF (HFmrEF) and preserved EF (HFpEF)) and New York Heart Association (NYHA) classification. Direct medical costs included cost items on outpatient management, inpatient management, medications, and non -pharmaceutical treatments. Indirect cost was calculated based on the lost productivity due to absenteeism and presenteeism. Results: 51.4%, 19.5%, and 29.1% of the patients were estimated to be HFrEF, HFmrEF, and HFpEF patients, respectively. The total annual direct medical cost per patient was $887 and non-pharmaceutical treatments ($373, 42.1%) were the major direct cost driver. Since an estimated nationwide number of HF patients is 1,128,000 in 2021, the total annual national economic burden of HF is estimated to be $1 billion in 2021. The direct medical cost was higher in patients with HFrEF than in those with HFmrEF or HFpEF ($1,147 vs. $555 and $649, respectively). Average indirect cost per patient was calculated to be $3,386 and was similar across HFrEF, HFmrEF and HFpEF groups, but increased with advanced NYHA stage. Conclusion: Our findings confirm the substantial economic burden of HF in terms of both direct and indirect costs and indicate that the non-pharmaceutical cost is the major direct medical cost driver in HF management, regardless of the EF status of HF patients.Item Recommendations for Ramadan Fasting to Patients with Cardiovascular Diseases; Turkish Society of Cardiology Consensus Report(2021) Alper, Ahmet Taha; Akboga, Mehmet Kadri; Ozcan, Kazim Serhan; Tengiz, Istemihan; Turk, Ugur Onsel; Yildiz, Mustafa; Yilmaz, Mehmet Birhan; Kayikcioglu, Meral; Gazi, Emine; Yildirir, Aylin; 33960303Item Management of Hyperkalemia in Heart Failure(2021) Altay, Hakan; Cavusoglu, Yuksel; Celik, Ahmet; Demir, Serafettin; Kilicarslan, Baris; Nalbantgil, Sanem; Temizhan, Ahmet; Tokgoz, Bulent; Ural, Dilek; Yesilbursa, Dilek; Yildirimturk, Ozlem; Yilmaz, Mehmet Birhan; 34738907Hyperkalemia is a common electrolyte abnormality in heart failure (HF) that can cause potentially life-threatening cardiac arrhythmias and sudden cardiac death. HF patients with diabetes, chronic kidney disease and older age are at higher risk of hyperkalemia. Moreover, hyperkalemia is also often associated with the use of renin-angiotensin-aldosterone system inhibitors (RAASi) including angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, mineralocorticoid receptor antagonists and sacubitril-valsartan. In clinical practice, the occurrence of hyperkalemia is a major concern among the clinicians and often limits RAASi use and/ or lead to dose reduction or discontinuation, thereby reducing their potential benefits for HF. Furthermore, recurrent hyperkalemia is frequent in the long-term and is associated with an increase in hyperkalemia-related hospitalizations. Therefore, management of hyperkalemia has a special importance in HF patients. However, treatment options in chronic management are currently limited. Dietary restriction of potassium is usually ineffective with variable adherence. Sodium polystyrene sulfonate is commonly used, but its effectiveness is uncertain and reported to be associated with intestinal toxicity. New therapeutic options such as potassium binders have been suggested as potentially beneficial agents in the management of hyperkalemia. This document discusses prevalence, predictors and management of hyperkalemia in HF, emphasizing the importance of careful patient selection for medical treatment, uptitration of the doses of RAASi, regular surveillance of potassium and treatment options of hyperkalemia.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 Natriuretic Peptides in Clinical Practice(2019) Cavusoglu, Yüksel; Alper, Ahmet Taha; Altay, Hakan; Celik, Ahmet; Demirkan, Burcu; Guvenc, Tolga Sinan; Kucukoglu, Mehmet Serdar; Nalbantgil, Sanem; Ozdemir, Murat; Ozin, Bulent; Sayin, Tamer; Yildirimturk, Ozlem; Yilmaz, Mehmet Birhan; Zorkun, Cafer; 30860204; AAE-1392-2021; AAD-9938-2021Natriuretic peptides have long been introduced into clinical practice. These biomarkers have certainly been shown to provide useful information in the diagnosis, prognosis and risk stratification in heart failure and also may have a role in the guidance of heart failure therapy. Although, there are some limitations in using of these markers such as lack of specificity, aging, renal dysfunction or obesity, among the huge number of candidates for heart failure biomarkers, only natriuretic peptides are currently widely used in daily clinical practice in heart failure. Recent heart failure guidelines recognize natriuretic peptides as an essential tool in the new diagnostic and therapeutic algorithms. Furthermore, natriuretic peptides are not only used in the diagnosis or prognosis of heart failure, but also these biomarkers are referred to have some potential role in primary prevention, cardio-oncology, advanced heart failure, assessment of response to cardiac resynchronization therapy, pulmonary arterial hypertension, acute coronary syndromes, atrial fibrillation and valvular heart disease. In this article, natriuretic peptides have been reviewed for their updated information and new recommendations in heart failure and also potential role of these biomarkers in the management of various clinical conditions have been addressed in the form of expert opinion based on the available data in the literature.Item Iron deficiency and anemia in heart failure(2017) Altay, Hakan; Cavusoglu, Yuksel; Cetiner, Mustafa; Guvenc, Tolga Sinan; Temizhan, Ahmet; Ural, Dilek; Yesibursa, Dilek; Yildirim, Nesligul; Yilmaz, Mehmet Birhan; 28446734; AAE-1392-2021Heart failure is an important community health problem. Prevalence and incidence of heart failure have continued to rise over the years. Despite recent advances in heart failure therapy, prognosis is still poor, rehospitalization rate is very high, and quality of life is worse. Co-morbidities in heart failure have negative impact on clinical course of the disease, further impair prognosis, and add difficulties to treatment of clinical picture. Therefore, successful management of co-morbidities is strongly recommended in addition to conventional therapy for heart failure. One of the most common co-morbidities in heart failure is presence of iron deficiency and anemia. Current evidence suggests that iron deficiency and anemia are more prevalent in patients with heart failure and reduced ejection fraction, as well as those with heart failure and preserved ejection fraction. Moreover, iron deficiency and anemia are referred to as independent predictors for poor prognosis in heart failure. There is strong relationship between iron deficiency or anemia and severity of clinical status of heart failure. Over the last two decades, many clinical investigations have been conducted on clinical effectiveness of treatment of iron deficiency or anemia with oral iron, intravenous iron, and erythropoietin therapies. Studies with oral iron and erythropoietin therapies did not provide any clinical benefit and, in fact, these therapies have been shown to be associated with increase in adverse clinical outcomes. However, clinical trials in patients with iron deficiency in the presence or absence of anemia have demonstrated considerable clinical benefits of intravenous iron therapy, and based on these positive outcomes, iron deficiency has become target of therapy in management of heart failure. The present report assesses current approaches to iron deficiency and anemia in heart failure in light of recent evidence.
