Gender-related clinical variations in patients with acute heart failure have been described in previous studies. However, there is still a lack of research on gender differences in patients hospitalized for acute heart failure in Türkiye. The aim of this study is to compare the clinical features, in-hospital approaches, and outcomes of male and female patients hospitalized for acute heart failure. Differences in clinical characteristics, medication prescription, hospital management, and outcomes between males and females with acute heart failure were investigated from the Journey Heart Failure-Turkish Population study. Nine hundred eighteen patients (57.2%) were men and 688 (42.8%) were women. Women were older than men (70.48 ± 13.20 years vs. 65.87 ± 12.82 years; P <.001). The frequency of comorbidities such as hypertension (72.7% vs. 62.4%, P <.001), diabetes (46.5% vs. 38.5%, P = .001),  atrial  fibrillation  (46.5%  vs.  33.4%,  P <.001), New York Heart Association class III-IV symptoms (80.6% vs. 71.2%, P =.001), and dyspnea in the rest (73.8% vs. 68.3%, P =.044) were more common in women on admission. Male patients were more frequently hospitalized with reduced left ventricular ejection fraction (51.0% vs. 72.4%, P <.001). In-hospital mortality was higher among female patients (9.3% vs. 6.4%, P =.022). Higher  New  York  Heart  Association  class,  lower  estimated  glomerular  filtration  rate, higher N-terminal pro-B type natriuretic peptide on admission, and mechanical ventilation usage were the independent parameters of in-hospital mortality, whereas the female gender was not. Our study clearly demonstrated the diversity in presentation, management, and in-hospital outcomes of acute heart failure between male and female patients. Although left ventricular systolic functions were better in female patients, in-hospital mortality was higher. Recognizing these differences in the management of heart failure in different sexes will serve better results in clinical practice.

Atrial fibrillation (AF) is strongly associated with an increased risk of ischemic events. Anticoagulation focuses on reducing the risk of embolism. Guideline recommended CHA2DS2-VASc scoring system is most widely used; however, different scoring systems do exist. Thus, we sought to assess the impact of anticoagulant treatment and different scoring systems on the development of stroke, myocardial infarction, and all-cause mortality in patients with nonvalvular AF. The present study was designed as a prospective cohort study. The enrollment of the patients was conducted between August 1, 2015, and January 1, 2016. The follow-up period was defined as the time from enrollment to the end of April 1, 2017, which also provided at least 12 months of prospective follow-up for each patient. A total of 1807 patients with AF were enrolled. During the follow-up, 2.7% (48) of patients had stroke, 0.8% (14) had myocardial infarction, and 7.5% (136) died. The anticoagulation and risk factors in AF (ATRIA) score had a better accuracy for the prediction of stroke compared to other scoring systems (0.729, 95% CI, 0.708-0.750, P <.05). Patients under low-dose rivaroxaban treatment had significantly worse survival (logrank P <.001). Age, CHA2DS2-VASc score, R2CHADS2 score, ATRIA score, chronic heart failure, prior stroke, and being under low-dose rivaroxaban treatment were independent predictors of clinical endpoint (P <.001). Low-dose rivaroxaban treatment was independently and strongly associated with the combined clinical endpoint. Furthermore, the ATRIA score proved to be a stronger predictor of stroke in the Turkish population.

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.

Aim: Paroxysmal nocturnal hemoglobinuria (PNH) a is a clonal disorder that may lead to several conditions such as thromboses, Budd-Chiari syndrome, renal failure, impotence, and pulmonary hypertension (pHT). Since the presentation of PNH may be occult, monitoring for clonal evolution is recommended in certain situations including aplastic anemia, Myelodysplastic syndrome, and unexplained cytopenia, and thrombosis. The prevalence of PNH clone in patients with idiopathic pHT is unknown. We designed a study to determine the prevalence of PNH clone in patients with idiopathic pHT, since it may be the first isolated presentation of the disease. Methods: A total of 45 patients with pHT were screened for PNH clone by proaerolysin conjugated with fluorescein. Results: Only two out of 45 patients had elevated lactate dehydrogenase (LDH) levels at presentation. PNH clone was detected in none of the patients. Conclusion: Screening for PNH clone in patients with pHT, who have normal LDH levels is unnecessary.

Risk assessment is recommended for patients with congenital heart disease-associated pulmonary arterial hypertension. This study aims to compare an abbreviated version of the risk assessment strategy, noninvasive French model, and an abridged version of the Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management 2.0 risk score calculator, Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2. We enrolled a mixed prevalent and incident cohort of patients with congenital heart disease-associated pulmonary arterial hypertension (n = 126). Noninvasive French model comprising World Health Organization functional class, 6-minute walk distance, and N-terminal pro-hormone of brain natriuretic peptide or brain natriuretic peptide was used. Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 includes functional class, systolic blood pressure, heart rate, 6-minute walk distance, brain natriuretic peptide/N-terminal pro-hormone of brain natriuretic peptide, and estimated glomerular filtration rate. The mean age was 32.17 ± 16.3 years. The mean follow-up was 99.41 ± 58.2 months. Thirty-two patients died during follow-up period. Most patients were Eisenmenger syndrome (31%) and simple defects (29.4%). Most patients received monotherapy (76.2%). Most patients were World Health Organization functional class I-II (66.6%). Both models effectively identified risk in our cohort (P =.0001). Patients achieving 2 or 3 noninva-sive low-risk criteria or low-risk category by Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 at follow-up had a significantly reduced risk of death. Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2 approximates noninvasive French model at discriminating among patients based on c-index. Age, high risk by Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension Disease Management Lite 2, and the presence of 2 or 3 low-risk criteria by noninvasive French model emerged as an independent predictors of mortality (multivariate hazard ratio: 1.031, 95% CI: 1.005-1.058, P =.02; hazard ratio: 4.258, CI: 1.143-15.860, P =.031; hazard ratio: 0.095, CI: 0.013-0.672, P =.018, respectively). Both abbreviated risk assessment tools may provide a simplified and robust method of risk assessment for congenital heart disease-associated pulmonary arterial hypertension. Patients not achieving low risk at follow-up may benefit from aggressive use of available therapies.

Chronic thromboembolic pulmonary hypertension (CTEPH) is one of the leading causes of pulmonary hypertension (PH). We aimed to investigate the outcome of CTEPH patients who were followed-up by a PH outpatient clinic. We screened the medical records of 29 PH patients who were followed-up by a PH outpatient clinic between 2009 and 2018. The patients' demographics and their clinical, echocardiographic, and hemodynamic characteristics were recorded. Our study group consisted of 16 females (55.2%) and 13 males (44.8%). The mean age was 59.5±13.7 years and the median follow-up duration was 44 months (1-113 months). The mean initial 6-minute walking distance (6MWD) was 321.4±119.9 m. The initial median N-terminal pro brain natriuretic peptide (NT-proBNP) level was 2468 pg/mL (46.1-20.564 pg/mL). All patients were on oral anticoagulant therapy. Pulmonary endarterectomy (PEA) was performed in 17 of 29 patients (58.6%). Twelve patients (41.4%) were not operated upon due to distal disease, comorbidities, or their own preference. The operated patients were younger than the non-operated patients (55 years & 65 years, p=0.04). At the follow-up, the 6MWD in the operated patients increased (+76 m) and decreased in non-operated patients (-46 m). The survival rate at 10-year follow-up was 58.6% for the whole group. Twelve patients died during the follow-up period. While 7 of 12 not-operated patients died (58.3%), just 5 of 17 operated patients (4 perioperatively and 1 at follow-up) died (29%). Advanced-stage final functional capacity (FC) [New York Heart Association (NYHA) III-IV], inoperability, lower final 6MWD, higher final NT-proBNP, and reduced tricuspid annular plane systolic excursion (TAPSE) were associated with an increased mortality rate. Univariate Cox regression analysis showed that patients with NYHA I-II final FC showed a 166-fold decreased mortality rate. The long-term prognosis of operated patients is better than the outcome of not-operated patients. The strongest predictor associated with mortality was a worse final FC (NYHA III-IV).
