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.

Turkish Real Life Atrial Fibrillation in Clinical Practice: TRAFFIC Study.

BACKGROUND: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia worldwide and is associated with an increased risk of thromboembolism, ischemic stroke, impaired quality of life, and mortality. The latest research that shows the prevalence and incidence of AF patients in Türkiye was the Turkish Adults' Heart Disease and Risk Factors study, which included 3,450 patients and collected data until 2006/07.The Turkish Real Life Atrial Fibrillation in Clinical Practice (TRAFFIC) study is planned to present current prevalence data, reveal the reflection of new treatment and risk approaches in our country, and develop new prediction models in terms of outcomes. METHODS: The TRAFFIC study is a national, prospective, multicenter, observational registry. The study aims to collect data from at least 1900 patients diagnosed with atrial fibrillation, with the participation of 40 centers from Türkiye. The following data will be collected from patients: baseline demographic characteristics, medical history, vital signs, symptoms of AF, ECG and echocardiographic findings, CHADS2-VASC2 and HAS-BLED (1-year risk of major bleeding) risk scores, interventional treatments, antithrombotic and antiarrhythmic medications, or other medications used by the patients. For patients who use warfarin, international normalized ratio levels will be monitored. Follow-up data will be collected at 6, 12, 18, and 24 months. Primary endpoints are defined as systemic embolism or major safety endpoints (major bleeding, clinically relevant nonmajor bleeding, and minor bleeding as defined by the International Society on Thrombosis and Hemostasis). The main secondary endpoints include major adverse cardiovascular events (systemic embolism, myocardial infarction, and cardiovascular death), all-cause mortality, and hospitalizations due to all causes or specific reasons. RESULTS: The results of the 12-month follow-up of the study are planned to be shared by the end of 2023. CONCLUSION: The TRAFFIC study will reveal the prevalence and incidence, demographic characteristics, and risk profiles of AF patients in Türkiye. Additionally, it will provide insights into how current treatments are reflected in this population. Furthermore, risk prediction modeling and risk scoring can be conducted for patients with AF.

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.

Relationship between left atrial functions and ambulatory blood pressure variability in patients with heart failure and preserved ejection fraction.

Aim    The aim of this study was to investigate the relationship between left atrial (LA) abnormalities and ambulatory blood pressure variability (BPV) in heart failure with preserved ejection fraction (HFpEF) patients.Material and methods    In this single-center, prospective study, we included 187 patients with HFpEF. Eighteen patients with poor image quality were excluded from the study. BPV was evaluated using 24-h ambulatory blood pressure (BP) monitoring. The standard deviation of systolic BP (SBP-SD) was calculated to assess BPV. The patients were classified into two groups according to median SBP-SD (10.5 mm Hg).Results    Overall, 169 HFpEF patients (69.2% women, mean age 69.2±11 yrs) were evaluated. There were 98 patients (57.9%) with a SBP-SD greater than 10.5 mm Hg. Patients with higher SPB-SD had significantly higher left atrial stiffness (LASt) and lower LA reservoir strain (LASr) than those with low SPB-SD. LASt was correlated with 24 hr SBP-SD in both sinus rhythm (r= 0.35, p= 0.015) and atrial fibrillation patients (r= 0.32, p= 0.005). There were significant correlations between night-time SBP-SD and LASr (r=-0.23, p=0.045) in HFpEF with sinus rhythm. For all HFpEF patients, multiple regression analyses showed that 24-hr SBP-SD was correlated with LASt (coeff.=0.40, 95%CI= 0.52-5.25, P= 0.017).Conclusions    High BPV is associated with impaired LA function, especially for LASt and LASr. This study may provide insight for larger multicenter studies to evaluate the effects on outcomes in HFpEF.

Vaccine-Induced Myocarditis in Two Intern Doctors in the Same Night Shift.

The coronavirus disease 2019 (COVID-19) pandemic has affected millions of people around the globe and vaccines against the disease have started to develop. Side effects of the vaccine have been reported in the literature, including myocarditis, which has a very low incidence and with a good prognosis. This case report aims to present two medical students' vaccine-induced myocarditis cases after the first doses of BNT162b2.These patients were young males with no previous medical history and both of them had good recovery after the disease. Both of them had their vaccine very recently before the event. These cases show that myocarditis can be seen after the first dose as well.Global vaccination is the most effective prevention method against COVID-19. Considering the fact that morbidities after the disease occur more than the side effects of the vaccine, they are still the best option against the current pandemic.

Clinical characteristics and in-hospital outcomes of COVID-19 patients with history of heart failure: a propensity score-matched study.

BACKGROUND: Data on the clinical course and outcomes of COVID-19 disease among patients with a history of heart failure (HF) are scarce. Therefore, the aim of this study was to assess the clinical characteristics, prognostic biomarkers and in-hospital outcomes of patients with a history of HF hospitalised with confirmed COVID-19. METHODS: A total of 8321 consecutive patients hospitalised with suspected COVID-19 disease were screened. Furthermore, 3849 patients with laboratory-confirmed SARS-CoV-2 infection were included in the study. Two hundred and forty COVID-19 patients with a history of HF and 240 without HF paired with PSM were evaluated. RESULTS: Mean age was 72.7 ± 9.90 years, and 64.6% were men. Oxygen saturation, systolic and diastolic blood pressure at admission were significantly lower and heart rate was significantly higher in patients with a history of HF compared to those without. Patients with HF, compared to those without, had significantly higher leukocyte count, D-dimer, CRP, procalcitonin, hsTnI, lactate and lower albumin and lymphocyte. Compared with patients without HF, those with previous HF had a longer length of stay at ICU (6.22 d vs. 3.71 d; p < 0.001), increased risk of mechanical ventilation (42.1% vs. 15.4%; p < 0.001), in-hospital death (39.2% vs. 15.4%; p < 0.001) and composite outcomes (52.9% vs. 17.1%; p < 0.001). CONCLUSION: History of HF is associated with a higher risk of mechanical ventilation, cardiogenic shock, mortality and longer ICU stay in patients hospitalised for COVID-19, therefore the diagnosis of HF alone is important for predicting clinical outcomes.

Assessment of fragmented QRS formation and its relationship with left ventricular hypertrophy in nonhypertensive acromegaly patients

Background/aim: It is known that the presence of fragmented QRS (fQRS) on electrocardiography (ECG) is associated with cardiovascular events. The aim of this study was the evaluation of fQRS formation and its relationship with the left ventricular hypertrophy (LVH) parameters in acromegaly patients. Materials and methods: In total, 47 previously diagnosed with non-hypertensive acromegaly patients and 48 control subjects were included in the study. ECG and transthoracic echocardiography (TTE) were performed for each participant. Acromegaly patients were divided into two groups according to the fQRS formation on the ECG. Left ventricular wall thicknesses, and left atrial diameter (LAD), left ventricular mass (LVM), left ventricular mass index (LVMi), and relative wall thickness (RWT) were obtained. Results: In control group 5 (10.4%) and in acromegaly group 17 (36.2%) patients had fQRS on ECG (p = 0.003). LAD [36.0 (34.0­38.0) vs. 38.0 (35.0­41.0) mm, p < 0.001], LVM [155.27 ± 27.00 vs. 173.0 (153.0­235.0) g, p < 0.001], LVMi [83.12 ± 13.19 vs. 92.0 (83.0­118.0) g/m², p < 0.001] and RWT [0.39 ± 0.03 vs. 0.43 (0.41­0.45), p = 0.001] were significantly higher in patients with acromegaly. Disease duration was significantly higher (11.59 ± 1.3 vs. 8.2 ± 1.8 years, p < 0.001) in the fQRS (+) group. LAD [41.0 (39.0­42.5) vs. 37.0 (34.7­38.0) mm, p < 0.001], LVM [219.0 (160.5­254.5) vs. 164.0 (153.0­188.0) g, p = 0.017], LVMi [117.0 (92.5­128.5) vs. 86.0 (82.0­100.2) g/m², p = 0.013] and RWT [0.44 (0.42­0.49) vs. 0.43 (0.40­0.44), p = 0.037] were significantly higher in fQSR (+) acromegaly patients. In multivariate logistic regression analysis, disease duration (odds ratio: 10.05, 95% CI: 1.099­92.012, p = 0.041) and LAD (odds ratio: 2.19, 95% CI: 1.030­4.660, p = 0.042) were found to be the independent predictors of fQRS formation. Conclusion: The results of our study revealed that fQRS (+) acromegaly patients had increased LVH parameters compared to fQRS (-) patients.

Assesment of Cerebral Blood Flow Velocities with Transcranial Doppler Ultrasonography in Heart Failure Patients with Reduced Ejection Fraction.

BACKGROUND: Heart and brain interaction is a well-known entity in heart failure (HF) and left ventricular systolic dysfunction poses an increased risk for stroke and cognitive impairment. Transcranial Doppler (TCD) provides valuable information on cerebral blood flow velocities (CBFV). However, less is known about CBFV in HF patients with reduced EF. So, we aimed to evaluate CBFV by means of TCD in patients with HF and reduced ejection fraction (HFrEF). METHODS: This study included 46 HFrEF patients (mean age 65.2±11 years, mean EF 20.1±3.8%) who underwent to TCD examination. In addition, 26 healthy individuals with sinus rhythm and EF >50% were included in the study as a control group. Peak systolic, mean and end diastolic flow velocities of the both right and left middle cerebral artery (RMCA and LMCA) were analyzed. In subgroup analysis, HFrEF patients compared according to rhythm. Correlation analyses was performed in HFrEF group between EF and TCD velocities. RESULTS: The average of RMCA and LMCA peak systolic and mean flow velocities were significantly lower in HF patients than those in control group (76,06±23,7 cm/s and 48,49±16,4 cm/s in HF group vs 87,84±14,5 cm/s and 56,41±10,7 cm/s in control group, p=0,025 and p=0,016, respectively, for RMCA and 75,1±22,3 cm/s and 47,57±14.8 cm/s in HF group vs 88,73±17,7 cm/s and 57,15±12,4 cm/s in control group, p=0,009 and p=0,007, respectively, for LMCA). The average mean flow velocity of RMCA and LMCA was significantly lower in HFrEF patients with AF than HFrEF patients with sinus rhythm. (P=0.04 and P= 0.03, respectively) In correlation analysis, EF was significantly positively correlated with both LMCA and RMCA flow velocities in HFrEF group. CONCLUSION: This study showed that HFrEF patients have lower CBFV as compared to healthy controls and HFrEF patients with AF rhythm have lower CBFV compared to HFrEF with sinus rhythm which might be one of the explanations of the adverse interaction between heart and brain in HFrEF.

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.
