Aims: We aimed to determine the use of sodium-glucose cotransporter 2 inhibitors (SGLT2is) and to identify clinical factors associated with their use in patients with heart failure (HF) in a real-life setting., Methods: Real-world data on Empagliflozin and Dapagliflozin use in patients with HEART failure: The RED-HEART study is a multicentre, cross-sectional and observational study that included HF patients in the outpatient setting regardless of ejection fraction from 19 cardiology centres between August 2023 and December 2023., Results: The study population consisted of 1923 patients with HF, predominantly men (61.2%), with a median age of 66 (range: 19-101) years. Overall, 925 patients (48.1%) were receiving SGLT2is. Among the study population, 22.1% had HF with preserved ejection fraction, 21.5% had HF with mildly reduced ejection fraction, 56.4% had HF with reduced ejection fraction and the use of SGLT2is was 42.0%, 47.9% and 50.6% in each group, respectively (P = 0.012). The use of SGLT2is was 76.6% in patients with HF and diabetes, 19.8% in patients with HF and chronic kidney disease and 26.8% in patients without diabetes and chronic kidney disease (P < 0.001). Higher education level [odds ratio (OR): 1.80; 95% confidence interval (CI): 1.06-3.05; P = 0.027], higher household income (OR: 3.46; 95% CI: 1.27-9.42; P = 0.015), New York Heart Association functional class IV (OR: 2.72; 95% CI: 1.16-6.35; P = 0.021), diabetes (OR: 9.42; 95% CI: 6.72-13.20; P < 0.001), the use of angiotensin receptor-neprilysin inhibitors (ARNis) (OR: 4.09; 95% CI: 2.39-7.01; P < 0.001), the use of mineralocorticoid receptor antagonists (MRAs) (OR: 2.02; 95% CI: 1.49-2.75; P < 0.001), the use of loop diuretics (OR: 1.62; 95% CI: 1.18-2.22; P = 0.003) and the use of thiazide diuretics (OR: 1.72; 95% CI: 1.30-2.29; P < 0.001) were independently associated with the use of SGLT2is. Conversely, atrial fibrillation (OR: 0.63; 95% CI: 0.45-0.88; P = 0.008), chronic kidney disease (OR: 0.53; 95% CI: 0.37-0.76; P = 0.001), the use of dihydropyridine calcium channel blockers (OR: 0.68; 95% CI: 0.48-0.98; P = 0.042) and the use of statins (OR: 0.67; 95% CI: 0.49-0.91; P = 0.010) were independently associated with the non-use of SGLT2is., Conclusions: The RED-HEART study provided comprehensive real-world data about implementing SGLT2is in patients with HF. These results suggest that there is a need for organized action and close collaboration between healthcare providers to improve the implementation of SGLT2is, especially in patients with HF with preserved ejection fraction and chronic kidney disease., (© 2024 The Author(s).

Objective: Integrating heart failure (HF) guideline recommendations into clinical practice takes time and is often suboptimal in real-life settings. Physician-related factors may be significant barriers to the adoption of these guidelines. This survey aims to assess the current opinions of cardiologists practicing in Türkiye regarding the management of heart failure with reduced ejection fraction (HFrEF)., Methods: The survey comprised 22 questions and was published on the SurveyMonkey platform., Results: A total of 177 cardiologists (mean age: 39.5 years; 73.3% male) participated in the survey. Of these, 38.7% worked in a training and research hospital, and 10.2% were specialists in HF. The threshold EF value to define HFrEF was ≤ 40% for 80.1% of the cardiologists. While 52.6% of physicians considered angiotensin receptor-neprilysin inhibitor (ARNi) treatment the most effective medication for HF, 62.7% would initiate HF treatment with an angiotensin-converting enzyme inhibitor (ACEi) instead of ARNi due to reimbursement and cost issues. More than half of the cardiologists (52.3%) stated that adding another class of HF medication is more important than up-titrating those already prescribed. Although 69.5% of the study participants indicated prescribing all four classes of HF medications during the initial hospitalization is feasible, most cardiologists preferred a sequential approach starting with ACEi/ARNi, followed by beta-blockers, mineralocorticoid receptor antagonists (MRAs), and sodium-glucose cotransporter 2 inhibitors (SGLT2i)., Conclusion: This survey highlights significant discrepancies between guideline recommendations and the real-life clinical practice of cardiologists in Türkiye. These results suggest that there is a need for organized action by healthcare providers to improve the implementation of guideline recommendations.

Purpose: Inappropriate dosing of direct oral anticoagulants is associated with an increased risk of stroke, systemic embolism, major bleeding, cardiovascular hospitalization, and death in patients with atrial fibrillation. The main goal of the study was to determine the prevalence and associated factors of inappropriate dosing of direct oral anticoagulants in real-life settings., Methods: This study was a multicenter, cross-sectional, observational study that included 2004 patients with atrial fibrillation. The study population was recruited from 41 cardiology outpatient clinics between January and May 2021. The main criteria for inappropriate direct oral anticoagulant dosing were defined according to the recommendations of the European Heart Rhythm Association., Results: The median age of the study population was 72 years and 58% were women. Nine-hundred and eighty-seven patients were prescribed rivaroxaban, 658 apixaban, 239 edoxaban, and 120 dabigatran. A total of 498 patients (24.9%) did not receive the appropriate dose of direct oral anticoagulants. In a logistic regression model, advanced age, presence of chronic kidney disease and permanent atrial fibrillation, prescription of reduced doses of direct oral anticoagulants or edoxaban treatment, concomitant use of amiodarone treatment, and non-use of statin treatment were significantly associated with potentially inappropriate dosing of direct oral anticoagulants., Conclusion: The study demonstrated that the prevalence of inappropriate direct oral anticoagulant dosing according to the European Heart Rhythm Association recommendations was 24.9% in patients with atrial fibrillation. Several demographic and clinical factors were associated with the inappropriate prescription of direct oral anticoagulants., (© 2022.

Aims: The use of guideline-directed medical therapy (GDMT) among patients with heart failure (HF) with reduced ejection fraction (HFrEF) remains suboptimal. The SMYRNA study aims to identify the clinical factors for the non-use of GDMT and to determine the prognostic significance of GDMT in patients with HFrEF in a real-life setting., Methods and Results: The SMYRNA study is a prospective, multicentre, and observational study that included outpatients with HFrEF. Patients were divided into three groups according to the status of GDMT at the time of enrolment: (i) patients receiving all classes of HF medications including renin-angiotensin system (RAS) inhibitors, beta-blockers, and mineralocorticoid receptor antagonists (MRAs); (ii) patients receiving any two classes of HF medications (RAS inhibitors and beta-blockers, or RAS inhibitors and MRAs, or beta-blockers and MRAs); and (iii) either patients receiving class of HF medications (only one therapy) or patients not receiving any class of HF medications. The primary outcome was a composite of hospitalization for HF or cardiovascular death. The study population consisted of 1062 patients with HFrEF, predominantly men (69.1%), with a median age of 68 (range: 20-96) years. RAS inhibitors, beta-blockers, and MRAs were prescribed in 76.0%, 89.4%, and 55.1% of the patients, respectively. The proportions of patients receiving target doses of guideline-directed medications were 24.4% for RAS inhibitors, 11.0% for beta-blockers, and 11.1% for MRAs. Overall, 491 patients (46.2%) were treated with triple therapy, 353 patients (33.2%) were treated with any two classes of HF medications, and 218 patients (20.6%) were receiving only one class of HF medication or not receiving any HF medication. Patient-related factors comprising older age, New York Heart Association functional class, rural living, presence of hypertension, and history of myocardial infarction were independently associated with the use or non-use of GDMT. During the median 24-month period, the primary composite endpoint occurred in 362 patients (34.1%), and 177 of 1062 (16.7%) patients died. Patients treated with two or three classes of HF medications had a decreased risk of hospitalization for HF or cardiovascular death compared with those patients receiving ≤1 class of HF medication [hazard ratio (HR): 0.65; 95% confidence interval (CI): 0.49-0.85; P = 0.002, and HR: 0.61; 95% CI: 0.47-0.79; P < 0.001, respectively]., Conclusions: The real-life SMYRNA study provided comprehensive data about the clinical factors associated with the non-use of GDMT and showed that suboptimal GDMT is associated with an increased risk of hospitalization for HF or cardiovascular death in patients with HFrEF., (© 2023 The Authors.

Objective: Oral anticoagulant therapy is the cornerstone of atrial fibrillation management to prevent stroke and systemic embolism. However, there is limited real-world information regarding stroke and systemic embolism prevention strategies in patients with atrial fibrillation. The aim of the ROTA study is to obtain the real-world data of anticoagulant treatment patterns in patients with atrial fibrillation., Methods: The ROTA study is a prospective, multicenter, and observational study that included 2597 patients with atrial fibrillation. The study population was recruited from 41 cardiology outpatient clinics between January 2021 and May 2021., Results: The median age of the study population was 72 years (range: 22-98 years) and 57.4% were female. The median CHA2DS2-VASc and HAS-BLED scores were 4 (range: 0-9) and 1 (range: 0-6), respectively. Vitamin K antagonists and direct oral anticoagulants were used in 15.9% and 79.4% of patients, respectively. The mean time in therapeutic range was 52.9% for patients receiving vitamin K antagonists, and 76% of those patients had an inadequate time in therapeutic range with <70%. The most common prescribed direct oral anticoagulants were rivaroxaban (38.1%), apixaban (25.5%), and edoxaban (11.2%). The rate of overuse of vitamin K antagonists and direct oral anticoagulants was high (76.1%) in patients with low stroke risk, and more than one-fourth of patients on direct oral anticoagulant therapy were receiving a reduced dose of direct oral anticoagulants. Among patients who were on direct oral anticoagulant treatment, patients with apixaban treatment were older, had higher CHA2DS2-VASc and HAS-BLED scores, and had lower creatinine clearance than the patients receiving other direct oral anticoagulants., Conclusions: The ROTA study provides important real-world information about anticoagulant treatment patterns in patients with atrial fibrillation.time in therapeutic range with <70%.

Objective: Resistin, a cysteine-rich peptide, is associated with atherosclerosis and diabetes. Resistin levels increase corresponding to coronary artery disease (CAD) and heart failure severity. Since resistin level tends to elevate with symptomatic heart failure, it is expected to be associated with left ventricular end-diastolic pressure (LVEDP). However, there is no relevant literature on the relationship between resistin levels and LVEDP. We aimed to evaluate the association between resistin levels and LVEDP, severity of CAD, carotid intima-media thickness (CIMT), and echocardiographic diastolic dysfunction parameters., Methods: For this study, 128 euvolemic patients with creatinine clearance >50 mg/dL and without acute coronary syndrome, who had typical chest pain or were stress test positive, were enrolled. Resistin level was measured by Enzyme-linked immunosorbent assays (ELISA) method. Severe CAD is defined as ≥50% stenosis in one of the major coronary arteries. LVEDP was measured during left heart catheterization., Results: After coronary angiography, 60 patients (46.9%) had severe CAD. The mean LVEDPs were similar for patients with and without severe CAD (p=0.480). The resistin levels did not differ between the groups (p=0.154). The resistin levels did not correlate with LVEDP (r=-0.045, p=0.627), ejection fraction (EF; r=0.110, p=0.228), the Gensini score (r=-0.091, p=0.328), and CIMT (r=0.082, p=0.457). No significant correlation was found between the echocardiographic diastolic dysfunction parameters and resistin levels., Conclusion: There was no significant correlation between resistin level and LVEDP, CAD severity, echocardiographic diastolic dysfunction parameters, and CIMT. Further studies are warranted to determine the efficacy of resistin in clinical use.

Presence of a persistent left superior vena cava (PLSVC) is generally clinically asymptomatic and discovered incidentally during central venous catheterization. However, PLSVC may cause technical difficulties during cardiac device implantation. An 82-year-old man with heart failure symptoms and an ejection fraction (EF) of 20% was scheduled for resynchronization therapy-defibrillator device (CRT-D) implantation. A PLSVC draining via a dilated coronary sinus into an enlarged right atrium was diagnosed. First, an active-fixation right ventricular lead was inserted into the right atrium through the PLSVC. The stylet was preshaped to facilitate its passage to the right ventricular apex. An atrial lead was positioned on the right atrium free wall, and an over-the-wire coronary sinus lead deployed to a stable position. CRT-D implantation procedure was successfully completed.
