RESUMO
AIMS: Right ventricular (RV) failure is one of the leading causes of death in patients with pulmonary hypertension (PH). Conventional echocardiographic parameters are not included in risk stratification and follow-up for prognostic assessment due to PH's diverse nature and the RV's complex geometry. RV outflow tract velocity time integral (RVOT VTI) is a simple, non-invasive estimate of pulmonary flow and an echocardiographic surrogate of RV stroke volume. In this study, we aimed to define the prognostic value of RVOT VTI in PH patients. METHODS: Sixty-three subjects with idiopathic PAH (IPAH) (n = 23), connective tissue disease-associated PAH (CTD-associated PAH) (n = 19) and chronic thromboembolic pulmonary hypertension (CTEPH) (n = 21) were retrospectively included. A comprehensive two-dimensional echocardiographic evaluation, including RVOT-VTI measurement, was performed during the follow-up and the New York Heart Association functional class (NYHA FC), 6 min walk distance (6MWD) and brain natriuretic peptide (BNP) levels were recorded. RESULTS: The median age of the whole cohort was 63 years (52-68), and 47 (74.6%) of the patients were women. The median follow-up period was 20 months (11-33), and 20 (31.7%) patients died in this period. BNP values were higher [317 (210-641) vs 161 (47-466), P = 0.02], and 6MWD values were lower [197.5 ± 89.5 vs 339 ± 146.3, P < 0.0001] in the non-survivor group, and the non-survivor group had a worse NYHA-FC (P = 0.02). Among echocardiographic data, tricuspid annular plane systolic excursion (TAPSE) (15.4 ± 4.8 vs 18.6 ± 4.2, P = 0.01) and RVOT VTI (11.9 ± 4.1 vs 17.2 ± 4.3, P < 0.0001) values were lower whereas right atrial area (RAA) (26.9 ± 10.1 vs 22.2 ± 7.1, P = 0.04) values were higher in the non-survivor group. The area under curve of the RVOT VTI for predicting mortality was 0.82 [95% confidence interval (CI) 0.715-0.940, P < 0.0001], and the best cut-off value was 14.7 cm with a sensitivity of 80% and specificity of 77%. Survival was significantly lower in subjects with RVOT VTI ≤ 14.7 cm (log-rank P < 0.0001). Survival rates for patients with RVOT VTI ≤ 14.7 cm were 70% at 1 year, 50% at 2 years, %29 at 3 years and 21% at 5 years. The univariate determinants of all-cause mortality were BNP [hazard ratio (HR) 1.001 (1.001-1.002), P = 0.001], 6MWD [HR 0.994 (0.990-0.999), P = 0.012] and NYHA-FC III-IV [HR 3.335 (1.103-10.083), P = 0.03], TAPSE [HR 0.838 (0.775-0.929), P = 0.001], RAA [HR 1.072 (1.013-1.135), P = 0.016] and RVOT VTI [HR 0.819 (0.740-0.906), P < 0.0001]. RVOT VTI was found to be the only independent determinant of mortality [HR 0.857 (0.766-0.960), P = 0.008]. CONCLUSIONS: The decreased RVOT VTI predicts mortality in patients with PH and each 1 mm decrease in RVOT VTI increases the risk of mortality by 14.3%. This parameter might serve as an additional parameter in the follow-up of these patients especially when 6MWD and NYHA-FC could not be determined.
RESUMO
OBJECTIVE: Heart failure is a leading cause of death and the most common diagnosis leading to hospitalization. Its awareness is lower than that of other cardiovascular diseases, both in the general population and among patients with heart failure (HF). This study aimed to establish the current level of knowledge about HF in patients with HF with reduced ejection fraction (HFrEF) and mildly reduced ejection fraction (HFmrEF) in Türkiye. METHODS: This questionnaire-based survey study is multicenter, conducted across 34 centers from December 2021 to July 2022. We performed a survey consisting of two sets of questions focusing on individual characteristics of the patients and HF-related knowledge. RESULTS: The study included a total of 2,307 outpatient HF patients, comprising 70.5% males and 29.5% females with a mean age of 64.58 ± 13 (56-74) years and a mean body mass index value of 32.5 ± 10 kg/m2. HFrEF and HFmrEF were determined in 74.7% and 25.3% of patients, respectively. Thirty percent of the patients were unaware that they had HF. While 28.7% of the patients thought that they had sufficient information about HF, 71.3% believed they lacked adequate knowledge. In the study, 25.2% of the participants identified dyspnea, 22% identified tiredness, and 25.4% identified leg edema as the most common symptoms of HF. Only 27.4% of patients recognized all three typical symptoms of HF. CONCLUSION: We found that the study population's knowledge about HF symptoms and the nature of the disease was poor. Educational and awareness activities are necessary to optimize outcomes and benefits.

Acute pulmonary embolism (APE) is a thromboembolism situation that can be central or peripheral. APE risk analysis and classification are essential for therapy planning. Our aim is to determine the novel MAPH score (including age, mean platelet volume (MPV), total protein, and hematocrit parameters) that can distinguish APE subtypes. Our retrospective cohort analysis includes 97 APE patients referred to the emergency medicine department who underwent pulmonary computed tomography angiography (CTA) in 24 h from 2020 to 2022. The hospital information system provided demographic, clinical, laboratory, and pulmonary CTA data. APE was classified into central (46 patients) and peripheral (51 patients) depending on the area of vascular involvement. The central APE group had higher hypertension (HT) (67.4%) and atrial fibrillation (AF) (39.1%) incidence than the peripheral APE group (all p values > 0.05). The central APE had higher total protein and platelet counts (p = 0.003 and p = 0.036), but peripheral APE had higher troponin values (p = 0.029). Central APE had 2.17 ± 0.85 MAPH and peripheral APE 1.76 ± 0.95 (p = 0.029). HT, AF, platelet count, and MAPH score differed significantly in univariate logistic regression (all p values < 0.05). However, only platelet count varied in multivariate logistic regression (p = 0.042). ROC curve analysis revealed that the MAPH score predicts central APE with 83% sensitivity and 45% specificity at a cut-off level of 1.5. The new MAPH score as an indicator of blood viscosity may distinguish between central and peripheral APE. Our result is significant, especially for centers with limited examinations, as it may accelerate the diagnosis and treatment processes. We think that our results might guide future investigations.

BACKGROUND: Hypertrophic cardiomyopathy (HCM) and Fabry disease (FD) are genetically inherited diseases with left ventricular hypertrophy (LVH) phenotype characteristics that cause adverse cardiac outcomes. OBJECTIVES: To investigate the demographic, clinical, biochemical, electrocardiographic (ECG), and echocardiographic (ECHO) differences between HCM and FD. METHODS: 60 HCM and 40 FD patients were analyzed retrospectively as a subanalysis of the 'LVH-TR study' after excluding patients with atrial fibrillation, pace rhythm, bundle branch blocks, and second and third-degree atrioventricular (AV) blocks. The significance level was accepted as <0.05. RESULTS: Male gender (p=0.048) and creatinine (p=0.010) are significantly higher in favor of FD; however, ST depression (p=0.028), QT duration (p=0.041), interventricular septum thickness (IVSd) (p=0.003), posterior wall thickness (PWd) (p=0.009), moderate-severe mitral regurgitation (MR) (p=0.013), and LV mass index (LVMI) (p=0.041) are significantly higher in favor of HCM in the univariate analyses. In multivariate analysis, statistical significance only continues in creatinine (p=0.018) and QT duration (0.045). FD was positively correlated with creatinine (rho=0.287, p=0.004) and HCM was positively correlated with PWd (rho=0.306, p=0.002), IVSd (rho=0.395, p<0.001), moderate-severe MR (rho=0.276, p<0.005), LVMI (rho=0.300, p=0.002), relative wall thickness (RWT) (rho=0.271, p=0.006), QT duration (rho=0.213, p=0.034) and ST depression (rho=0.222, p=0.026). CONCLUSION: Specific biochemical, ECG, and ECHO characteristics can aid in the differentiation and early diagnosis of HCM and FD.
FUNDAMENTO: A cardiomiopatia hipertrófica (CMH) e a doença de Fabry (DF) são doenças herdadas geneticamente com características fenotípicas de hipertrofia ventricular esquerda (HVE) que causam resultados cardíacos adversos. OBJETIVOS: Investigar as diferenças demográficas, clínicas, bioquímicas, eletrocardiográficas (ECG) e ecocardiográficas (ECO) entre CMH e DF. MÉTODOS: 60 pacientes com CMH e 40 pacientes com DF foram analisados retrospectivamente como uma subanálise do "estudo LVH-TR" após exclusão de pacientes com fibrilação atrial, ritmo de estimulação, bloqueios de ramo e bloqueios atrioventriculares (AV) de segundo e terceiro graus. O nível de significância foi aceito como <0,05. RESULTADOS: O sexo masculino (p=0,048) e a creatinina (p=0,010) são significativamente maiores a favor da DF; entretanto, infradesnivelamento do segmento ST (p=0,028), duração do QT (p=0,041), espessura do septo interventricular (SIVd) (p=0,003), espessura da parede posterior (PWd) (p=0,009), insuficiência mitral moderada a grave (IM) (p=0,013) e o índice de massa ventricular esquerda (IMVE) (p=0,041) são significativamente maiores a favor da CMH nas análises univariadas. Na análise multivariada, a significância estatística apenas permanece na creatinina (p=0,018) e na duração do intervalo QT (0,045). A DF foi positivamente correlacionada com a creatinina (rho=0,287, p=0,004) e a CMH foi positivamente correlacionada com o PWd (rho=0,306, p=0,002), IVSd (rho=0,395, p<0,001), IM moderada-grave (rho= 0,276, p<0,005), IMVE (rho=0,300, p=0,002), espessura relativa da parede (ERP) (rho=0,271, p=0,006), duração do QT (rho=0,213, p=0,034) e depressão do segmento ST (rho =0,222, p=0,026). CONCLUSÃO: Características bioquímicas, ECG e ECO específicas podem auxiliar na diferenciação e no diagnóstico precoce da CMH e da DF.

INTRODUCTION: Hypertrophic cardiomyopathy(HCM) is a genetic cardiomyopathy with a prevalence of 1/500 and causes adverse outcomes, usually due to left ventricular outflow tract obstruction. AIM: In this study, we aimed to determine the possible differences and predictors of obstructive hypertrophic cardiomyopathy HCM (Obs-HCM) and nonobstructive HCM (Nonobs-HCM) by electrocardiographic (ECG) and echocardiographic (ECHO) evaluations with clinical, demographic, and biochemical characteristics. METHODS: This study is a subgroup analysis of a multicentre, national, and observational 'LVH-TR study' that included 886 left ventricular hypertrophy(LVH) patients in 22 centres between February 2020 and August 2021. After excluding six patients with atrial fibrillation, pace rhythm, bundle branch blocks, and second, and third-degree atrioventricular(AV) block, 60 HCM patients were included, 23 of whom were obstructive, and 37 were nonobstructive. RESULTS: Body surface area(BSA) (2.01 ± 0.17, 1.89 ± 0.19; p = .01), ST-segment depression (%82.6, %54.1; p = .02), QT and QTc durations (436.3 ± 58.3, 398.0 ± 65.5; p = .02/470.6 ± 58.7, 432.8 ± 74.7; p = .04), left ventricular mass index(LVMI) (176.4 ± 47.0, 152.7 ± 10.2; p = .004), and systolic anterior motion(SAM) rates (%82.6, %18.9; p < 0.001) were significantly higher in the obstructive HCM compared to nonobstructive HCM. Furthermore, the significance of ST-segment depression, QT duration, LVMI, and SAM continued in the univariate analyses to assess obstruction prediction (all p values < .05). CONCLUSION: In multivariate and correlation analyses, ST segment depression (rho = 0.29), QT prolongation (rho = 0.34), and SAM (rho = 0.62) are found as predictors for obstruction (all p values < .05). Our study will guide future studies since it has detailed ECG and ECHO comparisons of Obs-HCM and Nonobs-HCM patients over 18 are made.
RESUMO
OBJECTIVE: The ventriculoarterial uncoupling has been linked with unfavorable results as measured noninvasively by tricuspid annular plane systolic excursion divided by systolic pulmonary artery pressure (TAPSE/sPAP). However, its prognostic importance in chronic thromboembolic pulmonary hypertension (CTEPH) is limited. Thus, we determine the effect of the TAPSE/sPAP ratio on outcomes and predictors of all-cause mortality in these patients. METHODS: We analyzed 56 subjects with medically treated CTEPH. Two-dimensional echocardiographic examination and right heart catheterization findings were recorded from the hospital database. Baseline New York Heart Association functional class (NYHA-FC), 6-min walk distance (6MWD), and brain natriuretic peptide (BNP) test results were recorded. RESULTS: The median age was 65.5 years. Over a median follow-up time of 27 months, 29 (51.8%) patients died. BNP values were higher (P = 0.008), 6MWD values were lower (P = 0.004), and NHYA-FC (P = 0.0001) was worse in the non-survivor group. TAPSE (P = 0.0001) and TAPSE/sPAP ratio (P = 0.001) were significantly lower and pulmonary vascular resistance (PVR) was higher in the non-survivor group (P = 0.03). The best cut-off value for the TAPSE/sPAP ratio for predicting mortality was 0.20 mm/mmHg and the survival rates were significantly lower in the TAPSE/sPAP ratio ≤0.20 group (log-rank P = 0.012). 6MWD (P = 0.005), NHYA-FC III-IV (P = 0.0001), TAPSE/sPAP ratio ≤0.20 (P = 0.017), PVR (P = 0.008), and TAPSE/sPAP ratio ≤0.20 combined with NYHA-FC III-IV (P = 0.0001) were significant determinants and TAPSE/sPAP ratio ≤0.20 combined with NYHA-FC III-IV was the only independent predictor of mortality (P = 0.003). CONCLUSION: Medically treated CTEPH patients with a TAPSE/sPAP ratio ≤0.20 had lower survival rates. TAPSE/sPAP ratio≤0.20 combined with NYHA-FC III-IV was the independent predictor of poor prognosis.

Aim Coronary artery tortuosity is a common coronary angiographic finding. This tortuosity can cause myocardial ischemia even in the absence of significant coronary artery stenosis. Our aim was to compare the demographic, clinical and echocardiographic features of patients with chronic coronary syndrome (CCS) and with and without coronary artery tortuosity.Material and methods 361 patients who underwent elective coronary angiography (CAG) due to CCS were included in the study. These patients divided into two groups, those with coronary tortuosity (Group 1) and those without (Group 2). Univariable and multivariable logistic regression analysis was performed to identify predictors associated with coronary artery tortuosity.Results The mean age of the 361 CCS patients (44â% female; 56â% male) was 56.7±11.5 years. In the univariable regression analysis, age, female sex, hypertension (HT), PR interval, QTc interval, STâ/âT segment changes, left ventricle diastolic dysfunction (LVDD), left ventricle hypertrophia (LVH) were identified as predictors of coronary tortuosity. In the multivariable regression analysis, age (OR: 1.059; 95â%CI: 1.032-1.087, p<0.001) and hypertension (OR: 0.484; 95â%CI: 0.278-0.843, p=0.01) were identified as independent predictors of coronary tortuosity.Conclusion Coronary artery tortuosity is an angiographic finding that develops as a result of adaptive mechanisms in the heart and can cause myocardial ischemia. Predictors of coronary artery tortuosity in patients with CCS were long PR and QTc intervals, STâ/âT segment changes, LVH, LVDD, advanced age, and female gender. Evaluation of these demographic, electrocardiographic, and echocardiographic data may help clinicans to anticipate coronary artery tortuosity in patients with CCS and to be precautious for PCI.

The MAPH (mean platelet volume, age, total protein and hematocrit) score is a newly developed simple scoring system for patients with STEMI that has been associated with satisfactory predictive values to determine thrombus burden in STEMI patients. Therefore, the aim of our study was to determine the relationship between the MAPH risk score and TIMI flow in patients with STEMI.The study included 260 patients who underwent primary percutaneous coronary intervention between December 2019 to July 2022, and had TIMI 0 flow in the responsible coronary artery due to STEMI. According to the TIMI flow score after stent implantation, the patients were classified into either the no-reflow group (n = 59) or the normal flow group (n = 201). In order to calculate the MAPH score, ROC analysis was performed to find the cutoff point for each component of the MAPH score. MAPH scores were calculated (MPV + Age + Protein + Hematocrit) for both groups. Our study was a retrospective, observational study.In the multivariable regression analysis, the MAPH score (OR: 0.567; 95%CI: 0.330-0.973, P = 0.04) and glycoprotein IIb/IIIa inhibitors (OR: 0.249; 95%CI: 0.129-0.483, P < 0.001) were parameters found to be independent predictors of TIMI flow. An MAPH score value > 2.5 predicted the presence of low TIMI coronary flow in patients with STEMI, with 78% specificity and 45% sensitivity (ROC area under curve: 0.691, 95% CI: 0.617-0.766, P < 0.001).The MAPH risk score is simple, inexpensive, and quick to calculate. A high MAPH score may be an indicator of coronary no-reflow in patients with STEMI.

BACKGROUND: Hypertrophic cardiomyopathy is a common genetic heart disease and up to 40%-60% of patients have mutations in cardiac sarcomere protein genes. This genetic diagnosis study aimed to detect pathogenic or likely pathogenic sarcomeric and non-sarcomeric gene mutations and to confirm a final molecular diagnosis in patients diagnosed with hypertrophic cardiomyopathy. METHODS: A total of 392 patients with hypertrophic cardiomyopathy were included in this nationwide multicenter study conducted at 23 centers across Türkiye. All samples were analyzed with a 17-gene hypertrophic cardiomyopathy panel using next-generation sequencing technology. The gene panel includes ACTC1, DES, FLNC, GLA, LAMP2, MYBPC3, MYH7, MYL2, MYL3, PLN, PRKAG2, PTPN11, TNNC1, TNNI3, TNNT2, TPM1, and TTR genes. RESULTS: The next-generation sequencing panel identified positive genetic variants (variants of unknown significance, likely pathogenic or pathogenic) in 12 genes for 121 of 392 samples, including sarcomeric gene mutations in 30.4% (119/392) of samples tested, galactosidase alpha variants in 0.5% (2/392) of samples and TTR variant in 0.025% (1/392). The likely pathogenic or pathogenic variants identified in 69 (57.0%) of 121 positive samples yielded a confirmed molecular diagnosis. The diagnostic yield was 17.1% (15.8% for hypertrophic cardiomyopathy variants) for hypertrophic cardiomyopathy and hypertrophic cardiomyopathy phenocopies and 0.5% for Fabry disease. CONCLUSIONS: Our study showed that the distribution of genetic mutations, the prevalence of Fabry disease, and TTR amyloidosis in the Turkish population diagnosed with hypertrophic cardiomyopathy were similar to the other populations, but the percentage of sarcomeric gene mutations was slightly lower.

AIM: We aimed to evaluate the awareness of pneumococcal vaccination (PCV13, PPSV23) in general cardiology outpatient clinics and impact of physicians' recommendations on vaccination rates. METHODS: This was a multicenter, observational, prospective cohort study. Patients over the age of 18 from 40 hospitals in different regions of Turkey who applied to the cardiology outpatient clinic between September 2022 and August 2021 participated. The vaccination rates were calculated within three months of follow-up from the admitting of the patient to cardiology clinics. RESULTS: The 403 (18.2%) patients with previous pneumococcal vaccination were excluded from the study. The mean age of study population (n = 1808) was 61.9 ± 12.1 years and 55.4% were male. The 58.7% had coronary artery disease, hypertension (74.1%) was the most common risk factor, and 32.7% of the patients had never been vaccinated although they had information about vaccination before. The main differences between vaccinated and unvaccinated patients were related to education level and ejection fraction. The physicians' recommendations were positively correlated with vaccination intention and behavior in our participants. Multivariate logistic regression analysis showed a significant correlation between vaccination and female sex [OR = 1.55 (95% CI = 1.25-1.92), p < 0.001], higher education level [OR = 1.49 (95% CI = 1.15-1.92), p = 0.002] patients' knowledge [OR = 1.93 (95% CI = 1.56-2.40), p < 0.001], and their physician's recommendation [OR = 5.12 (95% CI = 1.92-13.68), p = 0.001]. CONCLUSION: To increase adult immunization rates, especially among those with or at risk of cardiovascular disease (CVD), it is essential to understand each of these factors. Even if during COVID-19 pandemic, there is an increased awareness about vaccination, the vaccine acceptance level is not enough, still. Further studies and interventions are needed to improve public vaccination rates.
RESUMO
PURPOSE: In this prospective study we aimed to determine the rate of Fabry Disease (FD) in patients with left ventricular hypertrophy (LVH), and to evaluate the clinical presentations of patients with FD in a comprehensive manner. In addition, we aimed to raise awareness about this issue by allowing early diagnosis and treatment of FD. METHODS: Our study was planned as national, multicenter, observational. Totally 22 different centers participated in this study. A total of 886 patients diagnosed with LVH by echocardiography (ECHO) were included in the study. Demographic data, biochemical parameters, electrocardiography (ECG) findings, ECHO findings, treatments and clinical findings of the patients were recorded. Dry blood samples were sent from male patients with suspected FD. The α-Gal A enzyme level was checked and genetic testing was performed in patients with low enzyme levels. Female patients suspected of FD were genetically tested with the GLA Gene Mutation Analysis. RESULTS: FD was suspected in a total of 143 (16.13%) patients included in the study. The α-Gal-A enzyme level was found to be low in 43 (4.85%) patients whom enzyme testing was requested. GLA gene mutation analysis was positive in 14 (1.58%) patients. Male gender, E/e' mean ,and severe hypertrophy are important risk factor for FD. CONCLUSION: In daily cardiology practice, FD should be kept in mind not only in adult patients with unexplained LVH but also in the entire LVH population. Dry blood test (DBS) should be considered in high-risk patients, and mutation analysis should be considered in required patients.

BACKGROUND: The ACEF risk score (age, creatinine, and ejection fraction) has been associated with satisfactory predictive values not only for short-term and long-term mortality but also for major adverse cardiovascular events. OBJECTIVES: Investigate the relationship between ACEF risk score and degree of coronary artery stenosis. DESIGN: Retrospective, observational study. SETTING: Tertiary percutaneous coronary intervention center. PATIENTS AND METHODS: In patients with coronary coronary artery stenosis <70% were compared with patients with stenosis ≥70%. All were diagnosed with chronic coronary syndrome (CCS) and had undergone coronary computed tomography angiography (CTA). Receiver operating characteristic analysis was performed for the cut-off value of the ACEF risk score. Univariable and multivariable regression analyses were performed for significant parameters related to degree of coronary artery stenosis in coronary CTA. MAIN OUTCOME MEASURES: Relationship between ACEF risk score and degree of coronary artery stenosis in coronary CTA. SAMPLE SIZE: 148 patients. RESULTS: In the multivariable regression analysis; left ventricular ejection fraction (OR: 0.94; 95%CI: 0.89-0.99, P=.015) and ACEF risk score (OR: 5.63; 95% CI: 1.62-19.57, P=.007) were independent predictors for degree of coronary artery stenosis. The ACEF risk score was statistically significantly higher in with patients with stenosis ≥70% (1.43 [0.59]) than in patients with stenosis <70% (0.98 [0.35]), P<.001). An ACEF risk score value >1.04 was a predictor of the presence of severe coronary artery stenosis detected by coronary CTA in patients with CCS, with 66% sensitivity and 69% specificity. CONCLUSIONS: A high ACEF risk score (age, creatinine, ejection fraction) in patients with CCS is associated with the presence of severe coronary artery stenosis detected by coronary CTA, and was useful as an assessment tool for coronary angiography in patients with CCS. LIMITATIONS: Since we do not have long-term follow-up results, we do not know the prognostic value of the ACEF risk score in the long-term follow-up of patients with CCS. CONFLICT OF INTEREST: None.

BACKGROUND: This study aimed to assess the safety and tolerability of nebivolol in hypertensive patients with coronary artery disease and left ventricular ejection fraction ≥ 40% in a Turkish cohort. METHODS: A total of 1015 hypertensive patients and coronary artery disease with left ventricular ejection fraction ≥ 40% were analyzed from 29 different centers in Turkey. Primary outcomes were the mean change in blood pressure and heart rate. Secondary outcomes were to assess the rate of reaching targeted blood pressure (<130/80 mmHg) and heart rate (<60 bpm) and the changes in the clinical symptoms (angina and dyspnea). Adverse clinical events and clinical outcomes including cardiovascular mortality, cardiovascular hospital admissions, or acute cardiac event were recorded. RESULTS: The mean age of the study population was 60.3 ± 11.5 years (male: 54.2%). During a mean follow-up of 6 months, the mean change in blood pressure was -11.2 ± 23.5/-5.1 ± 13.5 mmHg, and the resting heart rate was -12.1 ± 3.5 bpm. Target blood pressure and heart rate were achieved in 76.5% and 37.7% of patients. Angina and functional classifications were improved by at least 1 or more categories in 31% and 23.2% of patients. No serious adverse events related to nebivolol were reported. The most common cardiovascular side effect was symptomatic hypotension (4.2%). The discontinuation rate was 1.7%. Cardiovascular hospital admission rate was 5% and hospitalization due to heart failure was 1.9% during 6 months' follow-up. Cardiovascular mortality rate was 0.1%. CONCLUSION: Nebivolol was well tolerated and safe for achieving blood pressure and heart rate control in hypertensive patients with coronary artery disease and heart failure with preserved or mildly reduced ejection fraction.

BACKGROUND: Left ventricular hypertrophy (LVH) is potentially modifiable cardiovascular risk factor often overlooked in clinical practice. For this reason, we planned to LVH-TR (Left Ventricular Hypertrophy in Turkish Population) trial to determine the aetiological causes and demographic characteristics of LVH patients. METHODS: Our study was a multicentre, national, observational study and included 886 patients who applied to the cardiology clinics in 22 centres between February 2020 and August 2021. In the initial evaluation, the Fabry disease (FD) and cardiac amyloidosis (CA) algorithm was followed in patients whose definitive etiologic cause(s) could not be identified. RESULTS: The most common aetiological causes of LVH in our study were hypertension with a rate of 56.6%, heart valve disease with 8.2%, and hypertrophic cardiomyopathy with 7.5%. Athlete's heart was detected in eight patients, LV non-compaction was detected in four patients. The rate of LVH of unknown cause was 18.8%. FD was suspected in 143 patients, and CA was suspected in 16 patients. There were 43 (4.85%) patients with low α-galactosidase A enzyme levels. GLA gene mutation analysis was positive in 1.58% of all patients, and these patients were diagnosed with FD, and 15 (1.69%) patients were diagnosed with CA by endomyocardial biopsy method. CONCLUSION: In the aetiology of LVH, the rate of LVH of unknown cause was high. FD and CA should be considered primarily in this patient group. Early diagnosis of the disease by following the schemes leading to FD and CA was essential in starting treatment before the progression of the disease.

BACKGROUND: The European Society of Cardiology has recently defined heart failure (HF) patient group with a left ventricular ejection fraction (LVEF) of 41-49% as a different category with the term heart failure with mildly reduced ejection fraction (HFmrEF). In this study, we aimed to conduct a research about the correlation between left atrial volume index (LAVI) and atrial fibrillation in patients HFmrEF. METHODS: A total of 282 patients HFmrEF who were admitted to the cardiology department from three different centres were included in the study. The study was planned as multicenter, cross-sectional study. The patients were divided into two groups as sinus rhythm and atrial fibrillation based on their electrocardiographic findings. RESULTS: It was found out that Nt-ProBNP, LA area, LAVI, pulmonary artery pressure, and severe mitral regurgitation rates were significantly higher in the AF group (p < 0.001). ROC analysis resulting in LAVI > 30.5 had 64% sensitivity and 66% specificity in the predicting presence of AF (ROC area under the curve: 0.660, 95% CI: 0.587-0.733, p < 0.001). We also observed that the LA area being >16.55 predicting presence of AF with 60% sensitivity and 58% specificity (ROC area under the curve: 0.624, 95% CI: 0.549-0.699, p = 0.002). CONCLUSION: In the study conducted, we found a correlation between AF and LAVI values in patients in the HFmrEF group. If the LAVI value increases in the follow-up of this group of patients with echocardiography, close follow-up in terms of AF may allow the early control and treatment of AF-related incidents.

OBJECTIVE: To find out whether there is any correlation between the fractional flow reserve (FFR) that indicates the severity of coronary artery disease (CAD), and the HbA1c value in non-diabetic patients. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Cardiology, Dicle University, Turkey, from September 2015 to November 2019. METHODOLOGY: Patients who underwent elective FFR procedure were included in the study. There were two groups formed according to FFR lesion severity: FFR <0.8 group (75 patients), FFR >0.8 group (39 patients). HbA1c was compared between the two groups. The relationship between categorical variables was examined with Pearson Chi-square and Fisher's Exact test. ROC (Receiver operating characteristic) analysis was performed for the HbA1c the cut-off value. RESULTS: The two groups were similar in terms of mean age and male gender ratios (58.4±9.6 vs. 57.9 ± 10.8 years, p=0.794; 64% vs. 74.4%, respectively, p=0.262). HbA1c value was statistically higher in the group with FFR value <0.8 [(5.8 (IQR: 5.7-6.0)] compared to the group with FFR value ≥0.8 [(5.5 (IQR: 5.2-6.0, p = 0.002)]. The HbA1c cut-off value was determined as 5.55. The ideal HbA1c threshold value calculated by the Youden index had 88% sensitivity, and 53.85% specificity. CONCLUSION: HbA1c, which shows the long-term glycemic index in non-diabetic individuals, is associated with the severity of CAD determined by the fractional flow reserve. Key Words: Coronary artery disease, fractional flow reserve, HbA1c.

BACKGROUND AND AIMS: The Friedewald equation (LDL-Cf) is known to produce inaccurate estimations of low-density lipoprotein cholesterol (LDL-C) when triglycerides are high (>400 mg/dL) or LDL-C is low (<70 mg/dL). The Martin/Hopkins (LDL-Cmh) and Sampson (LDL-Cs) equations were developed to overcome these limitations, but few data are available to assess whether these equations offer incremental usefulness over LDL-Cf. Our aim was to understand whether there was any incremental usefulness of novel equations on decisions regarding patient management. METHODS: Four thousand one hundred and ninety-six cardiology patients who were included in a multicentre registry database were analysed. Each patient was assigned to a cardiovascular risk class using the SCORE (Systematic COronary Risk Evaluation) algorithm, and relevant European guidelines were used to assess LDL-C targets. RESULTS: Compared with LDL-Cmh and LDL-Cs, LDL-Cf was able to correctly identify 96.9%-98.08% of patients as within or outside the LDL-C target, respectively, and 1.95%-2.8% of patients were falsely identified as being within the LDL-C target. Kappa coefficients for agreement between LDL-Cf vs LDL-Cmh and LDL-Cf vs LDL-Cs were 0.868 and 0.918 (P < .001). For patients not on cholesterol-lowering drugs, the decision to initiate treatment would be different in 1.2%-1.8% of cases if LDL-Cs or LDL-Cmh were used, respectively. For those already on cholesterol-lowering drugs, decisions regarding treatment intensification would be different in 1.5%-2.4% of cases if LDL-Cs or LDL-Cmh were used. CONCLUSIONS: In most cardiology outpatients, the Friedewald equation has excellent agreement with the novel Martin/Hopkins and Sampson equations, and treatment decisions should not change in most patients.

OBJECTIVES: Cardiovascular "risk" is an abstract concept that is frequently misunderstood by the general public. However, correct estimation of one's own cardiovascular risk is important as risk unawareness is associated with noncompliance with interventions aimed to reduce risk burden. Knowing the prevalence and factors linked with an increased probability of risk unawareness are therefore important to develop strategies aimed to increase risk awareness. Aims. To study prevalence of risk unawareness and to understand risk markers associated with risk underestimation and overestimation. Design. A total of 1716 participants were enrolled to the study in 33 centers across Turkey. Relevant demographic and clinical data were collected by direct interview. Cardiovascular risk of the participants was calculated using SCORE risk charts. Results. Ten-year risk for a fatal cardiovascular event was calculated as low in 633 (36.8%), intermediate in 513 (29.9%) and high-very high in 570 (33.2%) participants, respectively. According to these findings, 34.6% (n = 593) of the participants estimated their risk correctly, whereas 22.7% (n = 390) of the participants overestimated and 42.7% (n = 733) of the participants underestimated their risk. Male gender was the sole factor that was associated with an increased risk of underestimation, while having hypertension, significant valve disease or atrial fibrillation was associated with increased odds for risk overestimation. Conclusions. Only one-thirds of the sample was aware of their calculated risk for cardiovascular mortality and risk underestimation was the most common mode of risk unawareness, prompting concerns on the possible impact of the latter on adherence to the strategies aimed to reduce cardiovascular risk.

BACKGROUND: Infective endocarditis (IE) is an infection of the heart's endocardial surface. In recent years, nuclear imaging methods have gained importance in the diagnosis of IE. The present study aims to investigate the imaging potential of 99mTc-labeled vancomycin (99mTc-Vancomycin) as a new agent that would enable the diagnosis of IE in its early stages when it is difficult to diagnose or has small vegetation in the experimental rat model. METHODS: 99mTc-Vancomycin scintigraphy was evaluated for its accumulation in IE with Staphylococcus aureus performed in an experimental rat model. Serial planar scintigraphic and biodistribution analysis of infected vegetations are compared to rats with sterile vegetations. The heart was identified as an infected organ, the liver was identified as a non-infected organ and the heart/liver uptake ratio (T / NT ratio) was compared between infective endocarditis and sterile endocarditis groups. RESULTS: Planar scintigrams (in vivo measurements) showed more uptake in the heart of rats in the infective endocarditis group compared to the uptake in the heart of rats in the sterile endocarditis group, but this difference was not statistically significant (p>0.05). From the ex vivo measurements, the 99mTc-Vancomycin heart uptake increased significantly (p = 0.016), liver uptake was significantly decreased (p = 0.045) and the T/NT ratio was significantly higher (p = 0.014) in the infective endocarditis group compared to the sterile endocarditis group. CONCLUSION: In this experimental study, 99mTc-Vancomycin scintigraphy ensured the detection of ex vivo infected tissue in a rat model of IE. In addition, the absence of significant 99mTc-Vancomycin uptake in the sterile endocarditis group indicates that this agent targeted the infected tissue instead of the sterile inflammatory tissue. Finally, this agent should also be evaluated with animal- specific imaging devices.

OBJECTIVE: Radial endothelial dysfunction may occur after transradial coronary angiography (CAG). This study aimed to make a comparative evaluation of the radial endothelial functions before and after catheterization between three different radial access sites: left radial (LR) artery, left distal radial (LDR) artery, and right radial (RR) artery. METHODS: Seventy patients scheduled for elective transradial CAG and intervention from September 6, 2017 to March 6, 2018 were consecutively enrolled. Radial artery endothelial functions of the catheterization arm were measured by flow-mediated vasodilation (FMD) upon admission, at 24 hours, and 2 months following the procedure. RESULTS: LR access was used in 17 patients, whereas the LDR and the RR access were used in 27 and 26 patients, respectively. Basal radial diameters and FMD median values measured on the intervention arm were found to be similar between groups (LR 3.04±0.29 mm, 13.33%; LDR 2.79±0.31 mm; 13.64%; RR 2.74±0.29 mm; 12.52%, p=0.952). The radial vasodilation percentage change expressed as median decreased in all groups 24 hours after the procedure; however, the one with the LDR access was found to be significantly higher than with the LR (9.7% vs. 6.25% p=0.013) and the RR access (9.7% vs. 3.39 p<0.001). A partial recovery of endothelial functions was seen at 2 months after the procedure, approximating to basal values (11.11%; 12%; 10.62%, p=0.079, respectively). CONCLUSION: Radial artery functions deteriorate early after transradial catheterization. The LDR access seems safer than the other conventional radial access sites in terms of preservation of radial endothelial functions.
