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.

Effect of Smokeless Tobacco (Maras Powder) on the Epicardial Fat Thickness and Ventricular Repolarization Parameters.

Background and Objectives: Smokeless tobacco (ST) use has recently become an alternative to cigarettes, and it has been concluded that ST is at least as harmful as cigarettes. ST use is thought to play a role in the pathogenesis of arrhythmia by affecting ventricular repolarization. In this study, we aimed to examine the relationships of Maras powder (MP), one of the ST varieties, with epicardial fat thickness and new ventricular repolarization parameters, which have not previously been described. Materials and Methods: A total of 289 male individuals were included in this study between April 2022 and December 2022. Three groups, 97 MP users, 97 smokers, and 95 healthy (non-tobacco), were compared according to electrocardiographic and echocardiographic data. Electrocardiograms (ECG) were evaluated with a magnifying glass by two expert cardiologists at a speed of 50 m/s. Epicardial fat thickness (EFT) was measured by echocardiography in the parasternal short- and long-axis images. A model was created with variables that could affect epicardial fat thickness. Results: There were no differences between the groups regarding body mass index (p = 0.672) and age (p = 0.306). The low-density lipoprotein value was higher in the MP user group (p = 0.003). The QT interval was similar between groups. Tp-e (p = 0.022), cTp-e (p = 0.013), Tp-e/QT (p =0.005), and Tp-e/cQT (p = 0.012) were higher in the MP user group. While the Tp-e/QT ratio did not affect EFT, MP predicted the epicardial fat thickness (p < 0.001, B = 0.522, 95%CI 0.272-0.773). Conclusions: Maras powder may play a role in ventricular arrhythmia by affecting EFT and causing an increase in the Tp-e interval.

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.

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.

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.

Patients with HFpEF and HFmrEF have different clinical characteristics in Turkey: A multicenter observational study.

BACKGROUND: To determine and compare the demographic characteristics, clinical profile and management of patients with heart failure with mid-range ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF) in a Turkish cohort. METHODS: The APOLLON trial (A comPrehensive, ObservationaL registry of heart faiLure with mid-range and preserved ejection fractiON) is an observational and multicenter study conducted in Turkey. Consecutive patients admitted to the cardiology clinics who were at least 18 years of age and had HFmrEF or HFpEF were included (NCT03026114). RESULTS: The study population included 1065 (mean age of 67.1 ±â€¯10.6 years, 54% women) patients from 12 sites in Turkey. Among participants, 246 (23.1%) had HFmrEF and 819 (76.9%) had HFpEF. Compared to patients with HFpEF, those with HFmrEF were more likely to be male (57.7 vs 42.2%; p < 0.001), had higher N-terminal pro-B-type natriuretic peptide levels (853 vs 528 pg/ml, p < 0.001), were more likely to have ECG abnormalities (72.4 vs 53.5%, p < 0.001) and hospitalization history for heart failure (28 vs 18.6%; p = 0.002). HFmrEF patients were more likely to use ß-blockers (69.9 vs 55.2%, p < 0.001), aldosterone receptor antagonists (24 vs 14.7%, p = 0.001), statins (37 vs 23%, p < .001), and loop diuretics (39.8 vs 30.5%, p = 0.006) compared to patients with HFpEF. CONCLUSIONS: The results of APOLLON study support that the basic characteristics and etiology of HFmrEF are significantly different from HFpEF. This registry also showed that the patients with HFmrEF and HFpEF were younger but undertreated in Turkey compared to patients in western countries.

Rationale, Design, and Methodology of the APOLLON trial: A comPrehensive, ObservationaL registry of heart faiLure with midrange and preserved ejectiON fraction.

OBJECTIVE: Although almost half of chronic heart failure (HF) patients have mid-range (HFmrEF) and preserved left-ventricular ejection fraction (HFpEF), no studies have been carried out with these patients in our country. This study aims to determine the demographic characteristics and current status of the clinical background of HFmrEF and HFpEF patients in a multicenter trial. METHODS: A comPrehensive, ObservationaL registry of heart faiLure with mid range and preserved ejectiON fraction (APOLLON) trial will be an observational, multicenter, and noninterventional study conducted in Turkey. The study population will include 1065 patients from 12 sites in Turkey. All data will be collected at one point in time and the current clinical practice will be evaluated (ClinicalTrials.gov number NCT03026114). RESULTS: We will enroll all consecutive patients admitted to the cardiology clinics who were at least 18 years of age and had New York Heart Association class II, III, or IV HF, elevated brain natriuretic peptide levels within the last 30 days, and an left ventricular ejection fraction (LVEF) of at least 40%. Patients fulfilling the exclusion criteria will not be included in the study. Patients will be stratified into two categories according to LVEF: mid-range EF (HFmrEF, LVEF 40%-49%) and preserved EF (HFpEF, LVEF ≥50%). Regional quota sampling will be performed to ensure that the sample was representative of the Turkish population. Demographic, lifestyle, medical, and therapeutic data will be collected by this specific survey. CONCLUSION: The APOLLON trial will be the largest and most comprehensive study in Turkey evaluating HF patients with a LVEF ≥40% and will also be the first study to specifically analyze the recently designated HFmrEF category.

Real-world stroke prevention strategies in nonvalvular atrial fibrillation in patients with renal impairment.

BACKGROUND: The data regarding stroke prevention strategies in nonvalvular atrial fibrillation (NVAF) are limited especially in patients with renal impairment (RI). We sought to evaluate management dilemmas in patients with concurrent NVAF and RI in RAMSES (ReAl-life Multicenter Survey Evaluating Stroke Prevention Strategies inTurkey) study. METHODS: We conducted a prospective, multicenter, nation-wide registry in NVAF patients in outpatient cardiology clinics. All consecutive patients with NVAF were enrolled in RAMSES study (ClinicalTrials.gov identifier NCT02344901). The baseline data were collected. Glomerular filtration rate (GFR) was estimated by Cockcroft-Gault equation. RESULTS: A total number of 6273 patients from 29 provinces of Turkey with the contribution of 83 investigators were enrolled to the study. Of the study population, 1964(33%) patients had RI which was defined as GFR < 60 mL/min. Patients with RI had significantly higher CHA2 DS2 VASc and HAS-BLED scores compared to those without RI (3·9 ± 1·5 vs. 2·9 ± 1·5, and 2·0 ± 1 vs. 1·4 ± 1; P < 0·001). Prior history of major bleeding (6·9% vs. 4·1%, P < 0·001) and stroke (16·2% vs. 11·8%, P < 0·001) was significantly higher among individuals with concomitant RI and NVAF. Although RI patients had a higher risk for thromboembolism, number of the patients who did not receive any anticoagulant therapy was higher in patients with RI than without RI (30·1 vs. 26·4%, P = 0·003). CONCLUSION: RAMSES study showed that one-third of the patients with NVAF had RI in the real-world setting. Although it is mandatory in most of the patients with concomitant NVAF and RI, nearly one-third of these patients did not receive any anticoagulant therapy.

Gender-related differences in presentation and treatment of patients with non-valvular atrial fibrillation: results from RAMSES study.

OBJECTIVE: Gender is an important feature in the management of atrial fibrillation (AF). This study investigated gender-related differences in patients with AF in Turkey. METHODS: As a part of RAMSES (ReAl-life Multicenter Survey Evaluating Stroke prevention strategies in Turkey, NCT02344901) study, information of the patients with AF who successively applied to the hospital was analyzed. This cross-sectional, multicenter, nationwide observational study enrolled 6264 non-valvular AF (NVAF) outpatients (55.9% women) from Turkey. RESULTS: Compared with men, women with NVAF were older (71 years [range: 65-78 years] vs. 70 years [range: 62-77 years]; p<0.001), had lower frequency of coronary artery disease (22.0% vs. 38.3%; p<0.001) and congestive heart failure (18.2% vs. 27.2%; p<0.001). Women had higher median CHA2DS2-VASc score (4 [range: 3-5] vs. 3 [range: 2-4]; p<0.001), but similar HAS-BLED score (2 [range: 1-2] vs. 2 [range: 1-2]; p=0.141) when compared with men. Anticoagulant therapy use was higher in women (74.5% vs. 69.9%; p<0.001). Analysis of anticoagulation therapy use revealed that 68.5% of men and 61.6% of women (p=0.204) who had low risk for stroke (CHA2DS2-VASc score: 0 [male], 1 [female]) received anticoagulation therapy, and 30.5% of the men. Meanwhile, 25.3% of the women (p<0.001) with high risk for stroke (CHA2DS2-VASc score: ≥1 [male], ≥2 [female]) had not received any anticogulant therapy. CONCLUSION: Although women with NVAF receive better treatment than men, anticoagulation therapy is suboptimal in large proportion of men and women, with underuse in high-risk patients and overuse in low-risk patients. There is an urgent need to improve optimization of anticoagulation in patients with NVAF.

Impact of valvular heart disease on oral anticoagulant therapy in non-valvular atrial fibrillation: results from the RAMSES study.

The definition of non-valvular atrial fibrillation (NVAF) is controversial. We aimed to assess the impact of valvular heart disease on stroke prevention strategies in NVAF patients. The RAMSES study was a multicenter and cross-sectional study conducted on NVAF patients (ClinicalTrials.gov identifier NCT02344901). The study population was divided into patients with significant valvular disease (SVD) and non-significant valvular disease (NSVD), whether they had at least one moderate valvular disease or not. Patients with a mechanical prosthetic valve and mitral stenosis were excluded. Baseline characteristics and oral anticoagulant (OAC) therapies were compared. In 5987 patients with NVAF, there were 3929 (66%) NSVD and 2058 (34%) SVD patients. The predominant valvular disease was mitral regurgitation (58.1%), followed by aortic regurgitation (24.1%) and aortic stenosis (17.8%). Patients with SVD had higher CHA2DS2VASc [3.0 (2.0; 4.0) vs. 4.0 (2.0; 5.0), p < 0.001] and HAS-BLED [2.0 (1.0; 2.0) vs. 2.0 (1.0; 2.0), p = 0.004] scores compared to patients with NSVD. Overall, 2763 (71.2%) of NSVD and 1515 (73.8%) of SVD patients were on OAC therapy (p = 0.035). When the patients with SVD were analyzed separately, the mean CHA2DS2VASc and HAS-BLED scores were higher in patients with mitral regurgitation compared to patients with aortic regurgitation and aortic stenosis [4.0 (3.0; 5.0), 3.0 (2.0; 4.0), 3.0 (2.0; 4.0) p < 0.001 and 2.0 (1.0; 3.0), 1.0 (1.0; 2.0), 1.0 (0.0; 2.0) p < 0.001, respectively]. In patients with SVD, 65.7% of mitral regurgitation, 82.6% of aortic regurgitation and 88.0% of aortic stenosis patients were on OAC therapy. One out of three NVAF patients had at least one moderate valvular heart disease with the predominance of mitral regurgitation. Patients with SVD were at greater risk of stroke and bleeding compared to patients with NSVD. Although patients with mitral regurgitation should be given more aggressive anticoagulant therapy due to their higher risk of stroke, they are undertreated compared to patients with aortic valve diseases.

ReAl-life Multicenter Survey Evaluating Stroke prevention strategies in non-valvular atrial fibrillation (RAMSES study).

OBJECTIVE: Data regarding stroke prevention strategies in non-valvular atrial fibrillation (NVAF) are limited to vitamin K antagonists (VKAs). This study aimed to evaluate real-life stroke prevention strategies for NVAF patients in the era of non-VKA oral anticoagulants (NOACs). METHODS: We established a cross-sectional, multicenter, nationwide registry of NVAF patients. All consecutive atrial fibrillation (AF) patients and without mechanical heart valves or rheumatic mitral stenosis (but including those with any degree of mitral regurgitation) were enrolled in the ReAl-life Multicenter Survey Evaluating Stroke Prevention Strategies (RAMSES Study; ClinicalTrials.gov identifier NCT02344901) in Turkey. Baseline demographic data, medical history, and medications prescribed for NVAF treatment were collected. Univariate analyses were performed for continuous variables, and the chi-square test was used for categorical variables. RESULTS: In total, 6273 patients from 29 provinces of Turkey were enrolled in the study between February and May 2015, with the contribution of 83 investigators. The mean age was 69.6±10.7 years; 56% of the patients were females, and one-fifth of the patients had at least one comorbid disease, the most common being hypertension (69%). The mean CHA2DS2-VASc and HAS-BLED scores were 3.3±1.6 and 1.6±1.1, respectively. The rate of oral anticoagulant (OAC) therapy use was 72% (37% NOAC and 35% VKA). CONCLUSION: The RAMSES study showed a higher prevalence of OAC use among NVAF patients than that reported in previous studies. Although NOACs were preferred over VKAs in daily cardiology practice, there is a need for improved OAC therapies for NVAF patients.

Suboptimal use of non-vitamin K antagonist oral anticoagulants: Results from the RAMSES study.

This study aimed to investigate the potential misuse of novel oral anticoagulants (NOACs) and the physicians' adherence to current European guideline recommendations in real-world using a large dataset from Real-life Multicenter Survey Evaluating Stroke Prevention Strategies in Turkey (RAMSES Study).RAMSES study is a prospective, multicenter, nationwide registry (ClinicalTrials.gov identifier NCT02344901). In this subgroup analysis of RAMSES study, patients who were on NOACs were classified as appropriately treated (AT), undertreated (UT), and overtreated (OT) according to the European Society of Cardiology (ESC) guidelines. The independent predictors of UT and OT were determined by multivariate logistic regression.Of the 2086 eligible patients, 1247 (59.8%) received adequate treatment. However, off-label use was detected in 839 (40.2%) patients; 634 (30.4%) patients received UT and 205 (9.8%) received OT. Independent predictors of UT included >65 years of age, creatinine clearance ≥50 mL/min, urban living, existing dabigatran treatment, and HAS-BLED score of <3, whereas that of OT were creatinine clearance <50 mL/min, ongoing rivaroxaban treatment, and HAS-BLED score of ≥3.The suboptimal use of NOACs is common because of physicians' poor compliance to the guideline recommendations in patients with nonvalvular atrial fibrillation (NVAF). Older patients who were on dabigatran treatment with good renal functions and low risk of bleeding were at risk of UT, whereas patients who were on rivaroxaban treatment with renal impairment and high risk of bleeding were at risk of OT. Therefore, a greater emphasis should be given to prescribe the recommended dose for the specified patients.

Coronary artery disease in outpatients with nonvalvular atrial fibrillation: results from the multicenter RAMSES study.

BACKGROUND: Nonvalvular atrial fibrillation (NVAF) frequently coexists with coronary artery disease (CAD). However, the optimal antithrombotic strategy for patients with concomitant CAD and NVAF is controversial. The aim of this study is to assess the prevalence of CAD with NVAF and to determine antithrombotic treatment options in patients with or without a history of CAD. METHODS: ReAl-life Multicenter Survey Evaluating Stroke prevention strategies in Turkey (RAMSES study) was a cross-sectional, multicenter, nationwide observational study carried out in NVAF patients. We studied the clinical data of 6264 Turkish patients participating in the RAMSES study. Demographic properties and antithrombotic therapies were recorded and compared between patients with and without CAD. RESULTS: CAD was present in 1828 (29.2%) of patients with NVAF. Most of the NVAF patients with CAD were men (58%) and comorbid diseases were significantly more common in patients with CAD. Although patients with CAD had higher CHA2DS2VASc scores than those without disease (4.1±1.5 vs. 2.9±1.5; P=0.001), they had lower use of oral anticoagulant (OAC) therapy (66.1 vs. 74.4%, P=0.01). Among OAC drugs, warfarin was the preferred medication in patients with CAD (35.4 vs. 30.6%, P=0.01), whereas nonvitamin K antagonist oral anticoagulants were preferred in patients without CAD (40 vs. 34.3%, P=0.01). Patients with CAD required nearly three-fold higher antiplatelet treatment compared with patients without CAD (57.8 vs. 21.4%, P<0.001). CONCLUSION: CAD affects nearly one-third of patients with NVAF in a real-world setting. Although they merit more aggressive therapy, patients with CAD and NVAF were less likely to receive OAC therapy.

The relationship between serum asymmetric dimethylarginine levels and subjective sleep quality in normotensive patients with type 2 diabetes mellitus.

BACKGROUND/AIMS: Poor sleep quality (SQ) is associated with increased cardiovascular mortality and morbidity. Additionally, asymmetric dimethylarginine (ADMA) is an independent predictor of cardiovascular mortality and morbidity. However, no sufficient data regarding the relationship between ADMA levels and SQ have been reported. The goal of the current study was to evaluate the association between SQ and ADMA levels in normotensive patients with type 2 diabetes mellitus. METHODS: The study participants consisted of 78 normotensive type 2 diabetics. The SQ of all participants was assessed using the Pittsburgh Sleep Quality Index (PSQI). Patients with a global PSQI score > 5 were defined as "poor sleepers." Factors associated with poor SQ were analyzed using a multiple regression model. Serum ADMA levels were measured using high performance liquid chromatography. RESULTS: The median ADMA levels of the poor sleepers were increased compared with patients defined as good sleepers (5.5 [4.2 to 6.6] vs. 4.4 [2.9 to 5.4], p < 0.01, respectively). However, the L-arginine/ADMA ratio was decreased in poor sleepers (p < 0.01). Global PSQI scores were positively correlated with ADMA levels (p < 0.01) and negatively correlated with the L-arginine/ADMA ratio (p = 0.02). ADMA levels were correlated with sleep latency (p < 0.01) and sleep efficiency (p = 0.01). Logistic regression analysis showed that ADMA levels (odds ratio [OR], 1.68; 95% confidence interval [CI], 1.16 to 2.44; p = 0.01) and body mass index (OR, 1.15; 95% CI, 1.01 to 1.31; p = 0.04) were associated with poor SQ independently of glomerular filtration rate, sex, age, duration of diabetes, hemoglobin A1c, total cholesterol, and systolic blood pressure. CONCLUSIONS: Self-reported SQ was independently associated with ADMA levels in normotensive patients with diabetes mellitus.

The relationship between exercise capacity and masked hypertension in sedentary patients with diabetes mellitus.

AIM: Although exaggerated blood pressure responses (EBPR) to exercise have been related to future hypertension and masked hypertension (MHT), the relationship between exercise capacity and MHT remains unclear. A sedentary life style has been related to increased cardiovascular mortality, diabetes mellitus (DM), and hypertension. In this study, we aimed to examine the relationship between exercise capacity and MHT in sedentary patients with DM. METHODS: This study included 85 sedentary and normotensive patients with DM. Each patient's daily physical activity level was assessed according to the INTERHEART study. All patients underwent an exercise treadmill test, and exercise duration and capacity were recorded. Blood pressure (BP) was recorded during all exercise stages and BP values ≥ 200/110 mmHg were accepted as EBPR. MHT was diagnosed in patients having an office BP <140/90 mmHg and a daytime ambulatory BP >135/85 mmHg. Patients were divided into two groups according to their ambulatory BP monitoring (MHT and normotensive group). RESULTS: The prevalence of MHT was 28.2%. Exercise duration and capacity were lower in the MHT group than in the normotensive group (p<0.05) and were negatively correlated with age, HbA1c, mean daytime BP, and mean 24 hour BP. Peak exercise systolic BP and the frequency of EBPR were both increased in the MHT group (25.0% and 8.1%, respectively, p=0.03). According to a multivariate regression, exercise capacity (OR: 0.61, CI95%: 0.39-0.95, p=0.03), EBPR (OR: 9.45, CI95%: 1.72-16.90, p=0.01), and the duration of DM (OR: 0.84, CI95%: 0.71-0.96, p=0.03) were predictors of MHT. CONCLUSION: Exercise capacity, EBPR, and the duration of DM were predictors of MHT in sedentary subjects with DM.

Incidence and predictors of radial artery occlusion associated transradial catheterization.

In this study, we sought to assess the incidence and predictors of radial artery occlusion (RAO), which is a significant complication of transradial cardiac catheterization. We prospectively evaluated the results of 106 patients who underwent coronary angiography and percutaneous coronary intervention (PCI) via the transradial approach (TRA). At the 3(rd) h of intervention, the radial artery was checked by palpation; color doppler ultrasonography was performed at the 24(th) h. Fluoroscopy duration, procedure success, and complications of the radial artery were recorded. The procedure was successfully completed in all patients. RAO was detected in eight female and two male patients. In terms of RAO, there was a statistically significant difference between males and females (p=0.019). Other parameters did not show a significant correlation with RAO. Altough did not have any effect on procedural success, eight patients developed transient radial artery spasm. Gender was not associated with radial arterial spasms (p=0.19). TRA in the diagnosis and treatment of coronary artery disease has shown high procedural success and low complication rates; it addition, it presents a low economic burden. It should be used widely and be involved in the routine cardiology residency program.

The value of serum asymmetric dimethylarginine levels for the determination of masked hypertension in patients with diabetes mellitus.

BACKGROUND: An increased prevalence of masked hypertension (MHT) has been demonstrated among patients with diabetes mellitus (DM). MHT appears to cause cardiovascular (CV) complications similar to clinically overt hypertension. Asymmetric dimethylarginine (ADMA) is an endogenous nitric oxide inhibitor and higher plasma levels of ADMA are related to increased CV risk in both the general population and among patients with DM. The aim of this study was to evaluate the relationship between MHT and ADMA in diabetic patients. METHODS: This study included DM patients (n = 131) with normal office blood pressure (<140/90 mmHg). None of the participants were using antihypertensive medications. All participants utilized an ambulatory blood pressure monitor (ABPM) for 24 h. Serum ADMA and arginine levels were measured using the fluorescence detector high performance liquid chromatography method. RESULTS: The prevalence of MHT was 24.4% among the study subjects. ADMA levels were increased in the MHT group when compared with normotensive diabetics (6.2 ± 2.2 vs 4.2 ± 1.7 µmol/L p = 0.001, respectively). Furthermore, arginine/ADMA ratio was lower in the MHT group than among the normotensive group (29.9 ± 12.1 vs 46.0 ± 19.0 p = 0.001). In the multivariate logistic regression model, ADMA, BMI and HDL levels were found to be independent predictors of MHT Odds ratio: 1.63 (1.28-2.06), 1.19 (1.05-1.35), and 0.95 (0.90-0.99), respectively. The cut-off value of the ADMA was 4.34 µmol/L with a sensitivity, specificity, positive predictive value, and negative predictive value of 84.4%, 59.6%, of 40.3%, and 92.2%, respectively (AUC = 0.78). CONCLUSIONS: Serum ADMA may play a role in both the pathophysiology and screening of MHT in DM subjects.
