Baseline Characteristics of a Patient Cohort and Predictors of In-hospital MORtality in CORonary Care Units (MORCOR-TURK) Trial in Türkiye.

OBJECTIVE: The MORtality in CORonary Care Units in Türkiye (MORCOR-TURK) trial is a national registry evaluating predictors and rates of in-hospital mortality in coronary care unit (CCU) patients in Türkiye. This report describes the baseline demographic characteristics of patients recruited for the MORCOR-TURK trial. METHODS: The study is a multicenter, cross-sectional, prospective national registry that included 50 centers capable of 24-hour CCU service, selected from all seven geographic regions of Türkiye. All consecutive patients admitted to CCUs with cardiovascular emergencies between September 1-30, 2022, were prospectively enrolled. Baseline demographic characteristics, admission diagnoses, laboratory data, and cardiovascular risk factors were recorded. RESULTS: A total of 3,157 patients with a mean age of 65 years (range: 56-73) and 2,087 (66.1%) males were included in the analysis. Patients with arterial hypertension [1,864 patients (59%)], diabetes mellitus (DM) [1,184 (37.5%)], hyperlipidemia [1,120 (35.5%)], and smoking [1,093 (34.6%)] were noted. Non-ST elevation myocardial infarction (NSTEMI) was the leading cause of admission [1,187 patients (37.6%)], followed by ST elevation myocardial infarction (STEMI) in 742 patients (23.5%). Other frequent diagnoses included decompensated heart failure (HF) [339 patients (10.7%)] and arrhythmia [272 patients (8.6%)], respectively. Atrial fibrillation (AF) was the most common pathological rhythm [442 patients (14%)], and chest pain was the most common primary complaint [2,173 patients (68.8%)]. CONCLUSION: The most common admission diagnosis was acute coronary syndrome (ACS), particularly NSTEMI. Hypertension and DM were found to be the two leading risk factors, and AF was the most commonly seen pathological rhythm in all hospitalized patients. These findings may be useful in understanding the characteristics of patients admitted to CCUs and thus in taking precautions to decrease CCU admissions.

Different Cardio-Selective ß-Blockers and the Prevention of Exaggerated Blood Pressure Response During Exercise: A Retrospective Cross-Sectional Study.

OBJECTIVE: The aim of this study was to analyze the role of various ß-blockers in managing exercise-induced blood pressure escalations, referred to as exaggerated blood pressure response (eBPR). Despite the importance of this phenomenon, there is limited data on the efficacy of ß-blockers in controlling eBPR. METHOD: Our retrospective cohort for this study comprised 2,803 individuals who underwent treadmill tests from January 2016 to February 2018. A further subgroup analysis of 1,258 patients receiving ß-blocker treatment was performed to evaluate the influence of different ß-blockers on eBPR. RESULTS: The results demonstrated that ß-blockers play a significant role in mitigating the occurrence of eBPR (P = 0.026), irrespective of the specific type of ß-blocker. Additionally, no significant variance was observed in the development of eBPR among the different ß-blocker groups (P = 0.532 for systolic blood pressure (BP); P = 0.068 for diastolic BP). This finding remained consistent even among the 992 hypertensive patients, where no notable association was found between the type of ß-blocker and the development of eBPR (P = 0.736 for systolic BP; P = 0.349 for diastolic BP). It is noteworthy that patients using ß-blockers had unique clinical and demographic attributes. CONCLUSION: Our study suggests that ß-blockers can potentially deter the development of eBPR during physical activity, a benefit that is consistent across all types of ß-blockers. The study sheds light on prospective randomized studies on the use of eBPR as a new treatment target.

The 6-minute walk test and fall risk in patients with heart failure: A cross-sectional study.

BACKGROUND: Given the increased risk of falls in patients with heart failure (HF), there is limited information in the literature about the possible relationship between fall risk and functional capacity. OBJECTIVE: To investigate the relationship between functional capacity and fall risk in patients with HF and to determine whether there are differences in clinical parameters between patients with and without fall risk. METHODS: The study included 64 patients with HF. The Activity-Specific Balance Confidence Scale (ABC) determined the fall risk. Functional capacity was assessed with the 6-minute walk test (6MWT). The Berg Balance Scale (BBS), the timed up-and-go test (TUG), and the five times sit-to-stand (5-STS) test were used to evaluate functional balance and mobility. Comorbidities and dyspnea perception were assessed with the Charlson Comorbidity Index (CCI) and modified Medical Research Council (mMRC), respectively. RESULTS: The 6MWT was associated with fall risk in logistic regression with an odds ratio of 0.979 (0.970-0.989, p < 0.001). Furthermore, the 6MWT had a discriminative value for increased fall risk in patients with HF, with a cutoff value of 248 m. Patients with increased fall risk had lower 6MWT distance, BBS, and gait speed, and higher CCI and mMRC, number of falls, duration of TUG and 5STS compared to patients with no increased fall risk (p < 0.05). CONCLUSIONS: The study results demonstrated that 6MWT may be a clinically useful tool in quickly identifying potential balance problems and increased fall risk by providing insight into fall risk/balance confidence in addition to assessing functional capacity.

Misperceptions and management of LDL-cholesterol in secondary prevention of patients with familial hypercholesterolemia in cardiology practice: Real-life evidence from the EPHESUS registry.

BACKGROUND AND AIMS: Familial hypercholesterolemia (FH) is a common inherited disease, leading to premature atherosclerotic cardiovascular disease (ASCVD) due to elevated low-density lipoprotein cholesterol (LDL-C) levels. Achieving LDL-C goals is extremely important for preventing the complications of this fatal disease. We evaluated the management of FH patients with ASCVD in cardiology practice. METHODS: We analyzed patients with ASCVD from the nationwide EPHESUS registry, which was conducted in 40 cardiology outpatient clinics, and compared those with and without FH. RESULTS: Of the 1482 consecutively enrolled patients with ASCVD, 618 (41.7%) had FH, among which 455 were categorized as 'Possible FH' and 163 as 'Probable or Definite FH'. Proposed LDL-C goals were not attained in more than 90% of the patients with FH. The proportion of those on statin therapy was 77% for possible and 91% for probable or definite FH, whereas 34.2 % and 59.4% were in use of high-intensity statins, respectively. None of the patients were on PCSK-9 inhibitors, and only 2 used ezetimibe. Adverse media coverage was the most common cause of statin discontinuation (32.5% in 'possible FH' and 45.7% in 'probable/definite FH'). The negative impact of media in the decision to stop lipid lowering therapy (LLT) was increasing with education level. CONCLUSIONS: In real life most of the FH patients with ASCVD are undertreated in cardiology practice regarding statin dosing and combined LLT. Drug discontinuation rates are notably high and are mostly media-related, and side effects very rarely cause cessation of LLT. Urgent measures are needed to increase the awareness of FH among healthcare providers and patients and to develop improved treatment strategies aimed at preventing the complications of FH.

Comparing the Diagnostic Performance of HFA-PEFF and H2FPEF Scoring Systems in Heart Failure with Preserved Ejection Fraction Patients: Insights from the APOLLON Registry.

BACKGROUND: Heart failure with preserved ejection fraction is a complex and heterogeneous clinical syndrome, poses significant diagnostic challenges. The HFA-PEFF [Heart Failure Association of ESC diagnostic algorithm, P (Pretest Assessment), E  (Echocardiographic and Natriuretic Peptide score), F1 (Functional testing in Case of Uncertainty), F2 (Final Aetiology)] and H2FPEF [Heavy (BMI>30 kg/m2), Hypertensive (use of ≥2 antihypertensive medications), atrial Fibrillation (paroxysmal or persistent), Pulmonary hypertension (Doppler Echocardiographic estimated Pulmonary Artery Systolic Pressure >35 mm Hg), Elderly (age >60 years), Filling pressure (Doppler Echocardiographic E/e' >9)] scoring systems were developed to aid in diagnosing heart failure with preserved ejection fraction. This study aimed to assess the concordance and clinical accuracy of these scoring systems in the 'A comPrehensive, ObservationaL registry of heart faiLure with mildly reduced and preserved ejection fractiON' cohort. METHODS: A comPrehensive, ObservationaL registry of heart faiLure with mildly reduced and preserved ejection fractiON study was conducted as a multicenter, cross-sectional, and observational study; to evaluate a group of Heart failure with mildly reduced ejection fraction and heart failure with preserved ejection fraction patients who were seen by cardiologists in 13 participating centers across 12 cities in Türkiye. RESULTS: The study enrolled 819 patients with heart failure with preserved ejection fraction, with high probability heart failure with preserved ejection fraction rates of 40% and 26% for HFA-PEFF and H2FPEF scorings, respectively. The concordance between the 2 scoring systems was found to be low (Kendall's taub correlation coefficient of 0.242, P < .001). The diagnostic performance of both scoring systems was evaluated, revealing differences in their approach and ability to accurately identify heart failure with preserved ejection fraction patients. CONCLUSION: The low concordance between the HFA-PEFF and H2FPEF scoring systems underscores the ongoing challenge of accurately diagnosing and managing patients with heart failure with preserved ejection fraction. Clinicians should be aware of the strengths and limitations of each scoring system and use them in conjunction with other clinical and laboratory findings to arrive at an accurate diagnosis. Future research should focus on identifying additional diagnostic factors, developing more accurate and comprehensive diagnostic algorithms, and investigating alternative methods of diagnosis or stratification of patients based on different clinical characteristics.

How Did the Updated 2019 European Society of Cardiology/European Atherosclerosis Society Risk Categorization for Patients with Diabetes Affect the Risk Perception and Lipid Goals? A Simulated Analysis of Real-life Data from EPHESUS Study.

BACKGROUND: The recent 2019 European Society of Cardiology/European Atherosclerosis Society practice guidelines introduced a new risk categorization for patients with diabetes. We aimed to compare the implications of the 2016 and 2019 European Society of Cardiology/European Atherosclerosis Society guidelines with regard to the lipid-lowering treatment use, low-density lipoprotein cholesterol goal attainment rates, and the estimated proportion of patients who would be at goal in an ideal setting. METHODS: Patients with diabetes were classified into 4 risk categories according to 2019 European Society of Cardiology/European Atherosclerosis Society dyslipidemia guidelines from the database of EPHESUS (cross-sectional, observational, countrywide registry of cardiology outpatient clinics) study. The use of lipid-lowering treatment and low-density lipoprotein cholesterol goal attainment rates were then compared according to previous and new guidelines. RESULTS: This analysis included a total of 873 diabetic adults. Half of the study population (53.8%) were on lipid-lowering treatment and almost one-fifth (19.1%) were on high-intensity statins. While low-density lipoprotein cholesterol goal was achieved in 19.5% and 7.5% of patients, 87.4% and 69.6% would be on target if their lipid-lowering treatment was intensified according to 2016 and 2019 European Society of Cardiology/European Atherosclerosis Society lipid guidelines, respectively. The new target <55 mg/dL could only be achieved in 2.2% and 8.1% of very high-risk primary prevention and secondary prevention patients, respectively. CONCLUSION: The control of dyslipidemia was extremely poor among patients with diabetes. The use of lipid-lowering treatment was not at the desired level, and high-intensity lipid-lowering treatment use was even lower. Our simulation model showed that the high-dose statin plus ezetimibe therapy would improve goal attainment; however, it would not be possible to get goals with this treatment in more than one-third of the patients.

Prognostic value of D-dimer/fibrinogen ratio on in-hospital outcomes of patients with heart failure and COVID-19.

Aim: In the present study, the relationship between D-dimer/fibrinogen ratio (DFR) and in-hospital outcomes was evaluated in patients with COVID-19 and a diagnosis of heart failure (HF). Materials & methods: In-hospital outcomes were compared in patients with high and low DFR values. Results: With regard to in-hospital outcomes, patients in the third tertile of DFR had a higher rate of mechanical ventilation, cardiogenic shock and death (p < 0.001). The length of ICU stay was longer in the third tertile group (p < 0.001). When evaluated together with infection markers, DFR was found to be an independent predictor of outcomes. Conclusion: DFR can be used as a prognostic marker in patients with COVID-19 with a diagnosis of HF, and perhaps more valuable than other infection markers.

Management of LDL-cholesterol levels in patients with Diabetes Mellitus in Cardiology Practice: Real-life evidence of Under-treatment from the EPHESUS registry.

BACKGROUND AND AIMS: Effective treatment of high low-density lipoprotein cholesterol (LDL-C) levels has been shown to improve cardiovascular outcomes of patients with diabetes mellitus (DM). Herein, we aimed to provide insight to the real-life management of patients with DM in terms of LDL-C goal attainment and adherence to lipid management recommendations. Our objective was also to reveal the reasons of poor LDL-C goal attainment by assessing the perceptions of both physicians and patients. METHODS: We compared the diabetic and non-diabetic patients from the database of a nationwide registry conducted in cardiology outpatient clinics with regard to the demographic characteristics, educational status, comorbidities, medications, laboratory parameters and LDL-C goal attainment. Also, both the patients and attending physicians were surveyed to analyse perceptions and awareness of hypercholesterolemia. RESULTS: Of the 1868 consecutively enrolled patients, 873 (47%) had DM. Proportion of patients on statins was significantly lower in patients with DM (67.8% vs 55.3%; P < .001). The proportion of patients who attained LDL-C targets were lower among the diabetic patients (17.8% vs 15%; P = .06). The most common causes of the discontinuation of statin therapy were negative media coverage about statins (32.1%), and recommendations of physicians to stop the lipid lowering therapy (29.6%). Analysis of the physician survey revealed that the physicians could determine the off-target patients accurately (negative predictive value 98.4%) while the positive predictive value (48.8%) was low. The reasons for not attaining the LDL-C goals in diabetic patients were not prescription of statins (38%) and inadequate (eg low-dose, non-adherent) statin (28.3%) dosages. CONCLUSIONS: In real-life clinical cardiology practice, diabetic patients are far below the recommended LDL-C treatment goals. High-intensity statin treatment in diabetic population is still avoided because of the concerns about polypharmacy and drug interactions. Also, the inertia of physicians and even cardiologists is probably a major cause of refraining of prescription of optimal statin dosages.

The association of exaggerated hypertensive response to exercise and beta-blockers use in hypertensives.

PURPOSE: An elevation in blood pressure (BP) during exercise is the normal physiological response, however an abnormally exaggerated rise in BP, in terms of hypertensive response to exercise (HRE), is seen as a prognostic factor for end-organ damage and mortality. HRE is more common in hypertensive (HT) patients and data are lacking on the effect of antihypertensive medication on HRE. In this study, we evaluated patients who underwent treadmill exercise testing (TET) to reveal the effect of antihypertensive medication on HRE. MATERIALS AND METHODS: A cohort of 2970 individuals underwent TET and data were evaluated for HRE development. HRE has been defined as a systolic BP>210 mmHg in males and >190 mmHg in females throughout the TET. To reveal the effects of antihypertensive medication on HRE, 992 HT patients were analyzed. RESULTS: HRE was observed in 11.4% (n = 113) of HT patients and 5.9% (n = 107) of non-HT individuals(p < .001). HRE was observed significantly more in males (57.6% vs. 67.3%;p = .033), and in patients with higher body mass index BMI (29.1 ± 4.5 vs. 30.3 ± 5.2;0.033). There was no significant association between medication and HRE development apart from beta-blockers. Also, gender (odds ratio:1.787; 95%CI:1.160-2.751;p = .008), BMI (odds ratio:1.070;95%CI:1.025-1.116;p = .002) and being under beta-blocker treatment (odds ratio:0.637;95%CI:0.428-0.949;p = .026) were found to be independent predictors of HRE in multivariate logistic regression analysis. CONCLUSION: HRE was associated with gender, BMI and beta-blocker use in hypertensive with male gender and higher BMI associated with higher HRE, while beta-blocker-based treatment, either mono- or combination therapy, associated with lower HRE.

Comparison of clinical characteristics of patients with heart failure and preserved ejection fraction with atrial fibrillation versus sinus rhythm: Insights from the APOLLON registry.

OBJECTIVE: The aim of this study was to assess the clinical characteristics of patients with heart failure and preserved ejection fraction (HFpEF) and atrial fibrillation (AF) and compare them with those of HFpEF patients without AF. METHODS: This study was a sub-group analysis of a multicenter, observational, and cross-sectional registry conducted in Turkey (ClinicalTrials.gov identifier: NCT03026114). Patients with HFpEF were divided into 2 groups: HFpEF with AF and HFpEF with sinus rhythm (SR), and the clinical characteristics of the groups were compared. RESULTS: In a total of 819 HFpEF patients (median age: 67 years; 58% women), 313 (38.2%) had AF. Compared to the patients with SR, those with AF were older (70 years vs 66 years; p<0.001) and more symptomatic, with a higher rate of classification as New York Heart Association functional class III-IV, paroxysmal nocturnal dyspnea, orthopnea, palpitations, fatigue, pulmonary crepitations, and peripheral edema. The hospitalization rate for heart failure was higher (28.4% vs 12.6%; p<0.001) in patients with AF, and participants with AF had higher level of N-terminal pro-B-type natriuretic peptide (887 pg/mL vs 394.8 pg/mL; p<0.001) and higher left atrial volume index level. Patients without AF had a higher burden of diabetes mellitus, obstructive sleep apnea, and coronary artery disease. The prescription rate of nondihydropyridine calcium blockers, digoxin, loop diuretics, and anticoagulant drugs was higher in the AF group. CONCLUSION: The results of this study revealed that in a large Turkish cohort with HFpEF, significant clinical differences were present between those with and without AF and. Further prospective studies are needed to clarify the prognostic implications of AF in this growing heart failure population in our country.

The reasons of poor lipid target attainment for secondary prevention in real life practice: Results from EPHESUS.

OBJECTIVE: There are lack of studies considering the suboptimal management of dyslipidemia especially in cardiology outpatient clinics. This study was conducted to assess the patient adherence to cholesterol treatment recommendations and attainment of low-density-lipoprotein cholesterol (LDL-C) goals. METHODS: EPHESUS (NCT02608645) is a national, observational and multicenter registry which has been designed as a cross-sectional study to allow inclusion of all consecutive patients with hypercholesterolemia in cardiology outpatient clinics. The present subgroup analyses of the EPHESUS trial included patients with known peripheral artery disease or atherosclerotic cerebrovascular disease, and coronary heart disease namely secondary prevention. RESULTS: The present analysis of the EPHESUS study included 1482 patients (62.79 ± 10.4 years, 38.2% female) with secondary prevention from 40 sites in Turkey. Regarding recommended lipid targets for LDL-C, only 267 patients (18%) were below the target of 70 mg/dL. Females were significantly more off-target when compared with male patients (396, 85.5% vs 67, 14.5%; P = 0.017). Moreover, the achievement of LDL-C goal was significantly decreased with illiteracy (233, 19.2% vs 35, 13.1%; P = 0.02). Patients who think that the cholesterol treatment should be terminated when the cholesterol level of a patient has normalised were higher in the off-target group (34.0% vs 24.7%, P < 0.001). Besides, physician perceptions about LDL-C goal for secondary prevention were significantly related with LDL-C target attainment. CONCLUSIONS: EPHESUS is an important study with large population in terms of representing real-life practice of the adherence to dyslipidemia guidelines in secondary prevention patients in Turkey. Perceptions, knowledge, and compliance with the guidelines for secondary prevention have increased, but it is far below from the desired levels even in cardiology outpatient clinics. There is a need for patients' and physicians' education regarding the treatment of hyperlipidemia.

Gender disparities in heart failure with mid-range and preserved ejection fraction: Results from APOLLON study.

OBJECTIVE: This study aimed to examine gender-based differences in epidemiology, clinical characteristics, and management of consecutive patients with heart failure with mid-range ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF). METHODS: The APOLLON trial (A comPrehensive, ObservationaL registry of heart faiLure with mid-range and preserved ejection fractiON) is a multicenter, cross-sectional, and observational study. Consecutive patients with HFmrEF or HFpEF who were admitted to the cardiology clinics were included (NCT03026114). Herein, we performed a post-hoc analysis of data from the APOLLON trial. RESULTS: The study population included 1065 (mean age of 67.1+-10.6 years, 54% women) patients from 11 sites in Turkey. Compared with men, women were older (68 years vs. 67 years, p<0.001), had higher body mass index (29 kg/m2 vs. 27 kg/m2, p<0.001), and had higher heart rate (80 bpm vs. 77.5 bpm, p<0.001). Women were more likely to have HFpEF (82% vs. 70.9%, p<0.001), and they differ from men having a higher prevalence of hypertension (78.7% vs. 73.2%, p=0.035) and atrial fibrillation (40.7% vs. 29.9%, p<0.001) but lower prevalence of coronary artery disease (29.5% vs. 54.9%, p<0.001). Women had higher N-terminal pro-B-type natriuretic peptide (691 pg/mL vs. 541 pg/mL, p=0.004), lower hemoglobin (12.7 g/dL vs. 13.8 g/dL, p<0.001), and serum ferritin (51 ng/mL vs. 64 ng/mL, p=0.001) levels, and they had worse diastolic function (E/e'=10 vs. 9, p<0.001). The main cause of heart failure (HF) in women was atrial fibrillation, while it was ischemic heart disease in men. CONCLUSION: Clinical characteristics, laboratory findings, and etiological factors are significantly different in female and male patients with HFmrEF and HFpEF. This study offers a broad perspective for increased awareness about this patient profile in Turkey.

Geographical Variations in Patients with Heart Failure and Preserved Ejection Fraction: A Sub-Group Analysis of the APOLLON Registry

Background: Clinical characteristics of patients with heart failure may vary geographically. However, limited data are available regarding the geographical differences of patients with heart failure and preserved ejection fraction. Aims: The present subgroup analysis aims to investigate the geographical differences in clinical characteristics, management, and primary etiology of patients with heart failure and preserved ejection fraction in Turkey. Study Design: A cross-sectional study. Methods: A comPrehensive, ObservationaL registry of heart faiLure with mid-range and preserved ejection fractiON (APOLLON) is a multicenter and observational study conducted in seven regions of Turkey (NCT03026114). The present study is a post-hoc analysis of the APOLLON registry. In this substudy, we compared the clinical characteristics of 819 consecutive patients with heart failure and preserved ejection fraction (mean age, 67 years; 57.8% women) admitted to cardiology outpatient units in different geographical regions. Results: Based on the geographical distribution of the entire Turkish population, the highest number of patients enrolled were from Marmara (271 patients, 33.1%). All demographical characteristics, clinical and laboratory findings, comorbidities, primary etiology, and medications prescribed were significantly different between the regions. Furthermore, inter-regional gender differences were identified. Comparatively, the Aegean and Mediterranean regions had older patients with heart failure and preserved ejection fraction (p<0.001), and the Black Sea, Southeast, and East Anatolia regions had predominantly male patients (51.2, 54.5, and 56.9%, respectively; p=0.002). Notably, the Mediterranean and Southeast Anatolia had more symptomatic patients, and history of hospitalization for heart failure was more prevalent in Southeast Anatolia (33.3%, p<0.001). Prevalence of atrial fibrillation was higher in the Mediterranean and Southeast Anatolia regions (51 and 48.5%, p<0.001), and patients with heart failure and preserved ejection fraction had a higher prevalence of hypertension in the Mediterranean, Southeast Anatolia, and Black Sea regions (p=0.002). Angiotensin-converting enzyme inhibitors were more frequently prescribed in East Anatolia (52.3%, p=0.001), and the prevalence of patients with heart failure and preserved ejection fraction using loop diuretics (48.8%, p=0.003) was higher in the Black Sea region. Conclusion: This study was the first to show geographical differences in clinical characteristics of patients with heart failure and preserved ejection fraction in Turkey. Determination of the clinical characteristics of the heart failure and preserved ejection fraction population based on the geographical region may enables physicians to adopt a region-specific clinical approach toward heart failure and preserved ejection fraction.

Clinical features of heart failure with mid-range and preserved ejection fraction in octogenarians: Results of a multicentre, observational study.

OBJECTIVES: To compare real-world characteristics and management of individuals aged 80 and older with heart failure (HF) and mid-range ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF) derived from a large cohort of survey and to compare them with those younger than 80 from the same survey. METHODS: This is an observational, multicentre and cross-sectional study conducted in Turkey (NCT03026114). Consecutive 1065 (mean age of 67.1 ± 10.6 years) patients admitted to the cardiology outpatient units with HFmrEF and HFpEF were included. RESULTS: Participants aged 80 and older (n = 123, 11.5%) were more likely to be female (66.7% vs 52.5%, P = 0.003), had a higher prevalence of atrial fibrillation (49.6% vs 34%, P = 0.001), and anaemia (46.3% vs 33.4%, P = 0.005) than those who were younger than 80. N-terminal pro B-type natriuretic peptide levels were higher in those aged 80 and older than in those younger than 80 (1037 vs 550 pg/ml, P < 0.001). The prescription rates of HF medications (including in ACE-Is/ARBs, ß-blockers, MRAs, digoxin, ivabradine and diuretics) were similar (P > 0.05) in both groups. Octogenarians did not significantly differ from younger patients in the prevalence of HFmrEF (24.4% vs 22.9%) and HFpEF (75.6% vs 77.1%). Coronary artery disease was associated with HFmrEF (P < 0.05), whereas atrial fibrillation was associated with HFpEF (P < 0.05) in octogenarians. CONCLUSIONS: This study revealed that nearly 12% of the individuals with HFmrEF and HFpEF in this real-world sample were aged 80 and older. Participants aged 80 and older are more likely to be female and have more comorbidities than those who were younger than 80. However, HF medication profiles were similar in both groups. This study also showed that associated factors with HFmrEF and HFpEF were differ in octogenarians.
