RESUMEN
Tricuspid mitral valve is a rare entity, distinct from isolated clefts of the mitral leaflets. Echocardiographically, it manifests as the presence of three commissures, separate papillary muscles and concordant atrioventricular or ventriculoarterial connections. Three-dimensional transesophageal echocardiography helps distinguish the three cusps from clefts. Herein, we present a case of tricuspid mitral valve that led to severe mitral regurgitation.

OBJECTIVE: Contrast-induced nephropathy (CIN) is a serious complication in patients with ST segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (p-PCI). An interarm systolic blood pressure difference (IASBD) ≥10 mmHg has been identified as an independent risk factor for cardiovascular disease and mortality. The aim of this study was to evaluate the predictive value of the IASBD for the risk of CIN in patients with STEMI who underwent p-PCI. METHOD: We prospectively investigated 2120 consecutive patients who were hospitalized with a diagnosis of STEMI and underwent p-PCI. A relative increase in serum creatinine levels of ≥ 25% or an absolute increase of ≥ 0.5 mg/dL from baseline within 72 h of contrast exposure was defined as CIN. The IASBD was calculated on admission to the emergency department. The risk of CIN was evaluated. RESULTS: The incidence of CIN was 6.6% (n = 139). The patients were divided into 2 groups based on the development of CIN. Age (p = .001), baseline creatinine levels (p < .001), DM (p < .001), HT (p < .001) and anemia (p = .001) were higher in patients with CIN. An IASBD ≥10 mmHg was noted in 13 (9.3%) patients in the CIN group and 83 (4.1%) (p = .001) in the non-CIN group (Table 1). According to the multivariate analysis, the IASBD was found to be a predictor of CIN development (OR: 2.36, 95% CI: 1.42-3.90, p: 0.001). CONCLUSION: The IASBD on admission can be a potential predictor of CIN development in patients with STEMI who underwent p-PCI.

Studies reported conflicting results on the effect of renin-angiotensin-aldosterone system (RAAS) blocker use on acute kidney injury (AKI) in patients undergoing elective coronary angiography but association in elderly patients with ST-elevation myocardial infarction (STEMI) is not known. Also, there are limited data on the effect of inflammatory markers on AKI. We aimed to investigate the effects of RAAS blocker pretreatment and inflammatory markers on AKI in this population. A total of 471 patients were compared according to presence of RAAS blocker pretreatment at admission. Conventional and inverse probability weighed conditional logistic regression were used to determine independent predictors of AKI. Mean age of the study group was 75.4 ± 7.1 years and 29.1% of the patients were female. AKI was observed in 17.2% of the study population. Weighted conditional multivariable logistic regression analysis revealed that AKI was associated with baseline creatinine levels and C-reactive protein/albumin ratio (CAR) (OR 2.08, 95% CI = 1.13-3.82, p = .02 and OR 1.19, 95% CI = 1.01-1.41, p = .04, respectively). No significant association was found between RAAS blocker pretreatment and AKI. CAR and elevated baseline creatinine levels were independent predictors of AKI in this patient group.

BACKGROUND: Malnutrition reflects the general condition of a patient including physical condition, protein turnover, and immune competence. Contrast-induced acute kidney injury (CI-AKI) is a disorder that adversely affects the prognosis of older adults. In our study, we aimed to show the relationship between CI-AKI and malnutrition status in elderly patients over 65 years of age with chronic coronary artery disease (CAD). METHODS: Study enrolled 360 consecutive patients with coronary angiography performed because of chronic coronary artery disease. Patients pre-procedural and post-procedural blood samples were taken and prognostic nutritional index (PNI), controlling nutritional status (CONUT) score, and geriatric nutritional risk index (GNRI) malnutrition scores were calculated. RESULTS: The median age of the patients included in the study was 69 (67-72, IQR) and CI-AKI was seen in 91 (25.2%) patients. Univariate regression analysis showed that age, diabetes mellitus, baseline creatinine, body weight-adapted contrast agent, haemoglobin, left ventricular ejection fraction, CONUT score, PNI score, and GNRI score were independent predictors of CI-AKI. In model 1, increase in CONUT score (2 to 5) (OR: 3.21 (2.11-4.88), in model 2, increase in PNI score (37.4 to 45) (OR: 0.34, (0.24-0.49)), and in model 3, increase in GNRI score (89.5 to 103.8) (OR: 0.55, (0.38-0.81)) were independently associated with the presence of CI-AKI. PNI showed better results than other models in discriminating the predictable capability for CI-AKI. CONCLUSION: Malnutrition assessment of elderly patients before performing diagnostic or interventional coronary procedures could help clinicians to identify patients with elevated risk for CI-AKI.

BACKGROUND: The relation between body mass index (BMI) and coronary artery disease (CAD) extension remains controversial. A new score was developed to estimate body fat percentage (BFP) known as Relative Fat Mass (RFM) Index. This study aimed to evaluate the value of RFM Index in predicting the severity of the CAD, compared with other anthropometric measurements. METHODS: A total of 325 patients with chronic CAD were investigated. RFM, BFP, BMI and other anthropometric characteristics of patients were measured before angiography. CAD severity was determined by SYNergy between percutaneous coronary intervention with TAXus and cardiac surgery trial (SYNTAX) Score. The association between SYNTAX Score and variables was evaluated using linear regression models. In order to compare the model performance, R-squared (R2), Akaike's information criterion, Bayesian information criterion and root mean square error were used. RESULTS: Univariate linear regression outcome variable, SYNTAX was used to determine whether there was any relationship between variables. Independent variables were included in the multivariable linear logistic regression models. The analysis showed that in model 1, RFM (ß coefficient: 2.31 (0.90 to 3.71), p=0.001)), diabetes mellitus (ß coefficient: 3.72 (1.67 to 3.76), p=0.004)), haemoglobin (ß coefficient: -2.12 (-3.70 to -0.53), p=0.03) and age (ß coefficient: 1.83 (0.29 to 3.37), p=0.02)) were statistically significant. The adjusted R2 values in model 1 were higher than model 2 (BFP) and model 3 (BMI) (0.155, 0.137 and 0.130, respectively), and χ2 values of RFM were higher than BFP and BMI (10.5, 3.4 and 1.0, respectively). CONCLUSION: RFM Index is a more reliable and compatible marker of obesity in showing the severity of CAD compared to BMI.

OBJECTIVES: We aimed to determine the effects of normal pregnancy on left atrial (LA) mechanics using 2-dimensional speckle-tracking echocardiography. METHODS: A total of 47 healthy women with singleton pregnancies were prospectively enrolled in this study. A total of 4 visits, including each trimester and postpartum at 6 months, were planned. Echocardiographic studies were performed with a Vivid 7 device equipped with a 2.5-MHz transducer (GE Vingmed Ultrasound AS, Horten, Norway). RESULTS: Although the LA reservoir phase strain showed a gradual decrease from the first trimester to the third trimester during pregnancy, the measurements in the postpartum period were found to return to initial levels (mean ± SD: first trimester, 40.3% ± 11.7%; second trimester, 37.5% ± 12.9%; third trimester, 33.5% ± 9.0%; postpartum, 42.1% ± 11.1%; P < .001). The LA pump function strain was also parallel to the LA reservoir strain and gradually decreased from the first trimester to the third trimester during pregnancy, and it was observed that rose to the initial level in the postpartum period (first trimester, 16.7% ± 7.4%; second trimester, 14.8% ± 5.5%; third trimester, 12.7% ± 4.3%; postpartum, 15.8% ± 5.5%; P < .001). CONCLUSIONS: We prospectively determined normal reference values for LA deformation parameters using speckle-tracking echocardiography in each trimester and the postpartum period in healthy pregnancy. These reference values may help identify subclinical LA dysfunction in several cardiovascular or systemic conditions. According to this study, these parameters decreased toward the third trimester during pregnancy and recovered in the postpartum period.

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.

BACKGROUND AND AIM OF THE STUDY: Bicuspid aortic valve (BAV), one of the most common congenital cardiac abnormalities, is the result of abnormal aortic leaflet formation during valvulogenesis. Recent studies have reported BAV to be associated with abnormal aortic stiffness, which has a negative impact on left ventricular (LV) diastolic function. The study aim was to investigate the relationship between LV diastolic function, as measured with two-dimensional speckle tracking echocardiography (2D-STE), and arterial stiffness. METHODS: A total of 38 patients with isolated BAV, and 18 age- and gender-matched healthy controls were enrolled prospectively. Patients with aortic valve velocity > 1.7 m/s, more than mild aortic regurgitation (AR) and ascending aorta diameter > 3.6 cm (indexed diameter > 2.1 cm/m2) were excluded. BAV was classified as either anterior-posterior (AP) orientation or right-left (RL) orientation. The LV diastolic function (E/A and E/Em ratio), left atrial (LA) volume index (LAVI), LA systolic strain and strain rate (SR) was assessed using echocardiography. Strain measurements were reported as longitudinal LA strain during ventricular systole (LA-Res), strain during late diastole (LA-Pump), and also as SR during ventricular contraction (LA-SR(s)), during passive ventricular filling (LA-SR(E)), and during active atrial contraction (LA-SR(A)) from four-chamber views. Arterial stiffness was evaluated by measuring the aortic pulse wave velocity (PWV), wave reflection was assessed by measuring the central systolic blood pressure (cSBP), central pulse pressure (cPP) and augmentation index (AIx) with applanation tonometry. RESULTS: The aortic diameter at the proximal ascending aorta was larger in patients with BAV than in controls. Compared to controls, the E/Em ratio and LAVI were significantly higher in BAV patients. Although PWV was higher in BAV patients than in controls, no differences were found between the groups in terms of cSBP, cPP and AIx. The BAV group was observed to have significant lower LA-Res and LA-Pump strain values compared to controls. Significant correlations were identified between the PWV and echocardiographic parameters of LV diastolic function determinants, such as LA-Res and LA-Pump. However, there were no significant differences between BAV subgroups in terms of LV diastolic parameters and PWV. CONCLUSION: Patients with isolated BAV have early features of subclinical LV diastolic dysfunction, as measured with 2D-STE. In addition, aortic stiffness assessed by PWV was impaired. The LV diastolic parameters were related to aortic stiffness.

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.
RESUMEN
BACKGROUND: Papillary muscle free strain has not been evaluated previously in hypertrophic cardiomyopathy (HCMP) patients. Our aim was to evaluate free papillary muscle free strain in HCMP patients and to find whether it has a value for prediction of sudden cardiac death (SCD) risk score. METHODS: Transthoracic echocardiography with tissue Doppler imaging, 2-D speckle tracking imaging (STI) of 55 HCMP patients and 45 controls were performed. HCMP patients were further divided into two groups according to their SCD risk score. Patients with risk score of less than 6 points constituted low/intermediate risk group, whereas patients with risk score of greater or equal to 6 points constituted high risk group. RESULTS: Interventricular septum, posterior wall, and left ventricular mass index were significantly higher, whereas mitral E/A ratio was significantly lower in HCMP patients compared to controls. Longitudinal apical 4C, 2C, 3C, global longitudinal LV strain, anterolateral papillary muscle (ALPM), posteromedial papillary muscle (PMPM) free strain were significantly reduced in HCMP group compared to control group. Global longitudinal strain and ALPM free strain were significantly lower in patients with high SCD risk score (-14.6 (-17.4 - -13.1) vs -11.6 (-13.2 - -10.1), p = 0.001 and -17.1 (-20.3 - -14.0) vs -9.2 (-12.6 - -7.5), p<0.001, respectively. Global longitudinal strain and ALPM free strain were statistically significantly correlated with SCD risk score (r = 0.480, p<0.001 and r = 0.462, p<0.001, respectively). Global longitudinal strain value of -12.60% had a sensitivity of 73.3% and specificity of 82.5% for predicting high SCD risk score (AUC: 0.787, 95% CI: 00.643-0.930, p = 0.001). ALPM free strain value of -12.95% had 66.7% sensitivity and 77.5% specificity for predicting high SCD risk score (AUC: 0.766, 95% CI: 0.626-0.905, p = 0.003). CONCLUSION: Papillary muscle free strain was reduced in HCMP patients. It might be used in risk stratification of these patients.

Several studies have shown that high uric acid (UA) and low serum albumin (SA) values increase the risk of cardiovascular disease and mortality in ST-elevation myocardial infarction (STEMI). We determined whether the uric acid/albumin ratio (UAR) is a predictor of mortality in STEMI patients. All patients who presented at our center with a diagnosis of STEMI and underwent percutaneous intervention from 2015 to 2020 were screened consecutively; 4599 patients were included. A Cox proportional hazards model was used to evaluate UAR, and adjusted predictors obtained from laboratory findings and clinical characteristics contributed to mortality. Also, a regression model was presented with a directed acyclic graph (DAG). The median age of the patients was 58 years (IQR [interquartile range]: 50-67); 3581 patients (77.9%) were male. The incidence of mortality in the entire patient group was 11.9%. Median follow-up duration of all groups was 42 months. Multivariate Cox proportional regression (model-1) analysis showed age (increase 50 to 67 years; HR [hazard ratio]: 1.34, 95% CI 1.18-1.52) and UAR (increase 1.15-1.73; HR: 1.33, 95% CI 1.16-1.52) were associated with mortality. UAR may be a prognostic factor for mortality in STEMI patients and an easily accessible parameter to identify high-risk patients.

OBJECTIVE: Discontinuation of metformin treatment is a frequently used approach in clinical practice in diabetic ST-segment elevation myocardial infarction patients using metformin in order to reduce the risk of contrast-induced acute kidney injury. There is insufficient evidence in the literature to support this approach. The aim of this study is to determine whether the risk of contrast-induced acute kidney injury is different in diabetic ST-segment elevation myocardial infarction patients using metformin compared to those not taking metformin. METHODS: The population of the study consisted of patients who applied to our centers that are covered by this study with the diagnosis of ST-segment elevation myocardial infarction and underwent primary percutaneous intervention between 2014 and 2019. Three forty-three diabetic patients that met the study inclusion criteria were divided into 2 groups as who have been receiving metformin and who have not. Patients' creatinine values at admission and peak creatinine values were compared in order to determine whether they have developed contrastinduced acute kidney injury. The 2 groups were compared using conditional logistic regression analysis conducted with the inverse probability weighting method. RESULTS: Non-weighted classic multivariable logistic regression analysis revealed that metformin use was not associated with acute kidney injury. Weighted conditional multivariable logistic regression revealed that the increase in the risk of acute kidney injury was associated with baseline creatinine levels [odds ratio: 1.49 (1.06-2.10; 95% CI) P=.02] and that the increase in the risk of contrast-induced acute kidney injury was not associated with metformin usage [odds ratio: 0.92 (0.57-1.50, 95% CI) P=.74]. CONCLUSION: No statistically significant difference was found between the metformin and nonmetformin users among the diabetic ST-segment elevation myocardial infarction patients who underwent primary percutaneous intervention in the risk of contrast-induced acute kidney injury.

Background: Diabetes, hypertension, hyperlipidemia and smoking are associated with coronary artery disease and ST-elevation myocardial infarction (STEMI). However, patients without any classic risk factors have a higher mortality rate in the post-STEMI period. The aim of this study was to investigate the relationship between in-hospital mortality and creatinine/albumin ratio in patients with STEMI without modifiable risk factors. Materials & methods: All patients included in this study with a diagnosis of STEMI and who underwent primary percutaneous intervention between 2016 and 2020 were retrospectively analyzed. Patients were included in the standard modifiable cardiovascular risk factor (SMuRF) group if at least diabetes, hypertension, smoking or hyperlipidemia was present according to risk factors. Patients without these risk factors were considered the non-SMuRF group. Results: Creatinine/albumin ratio was found to be higher in non-SMuRF patients with mortality (p < 0.001). In multivariate logistic regression analysis, ejection fraction, hemoglobin and SMuRF were found to be inversely associated with in-hospital mortality (odds ratio [OR]: 0.48, 95% CI: 0.35-0.66, p < 0.001; OR: 0.70, 95% CI: 0.56-0.88, p = 0.002; OR: 0.57, 95% CI: 0.34-0.95, p = 0.03, respectively). Conclusion: The creatinine/albumin ratio can be used as a predictor of mortality in these patients; it can help identify high-risk patients beforehand.

BACKGROUND: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial has been the largest study ever conducted among patients in Turkey regarding aspirin treatment. In the subgroup analysis of the hypertensive group of the Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial, we aimed to evaluate the physicians' adherence to current guidelines regarding their aspirin treatment preferences. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study trial is a cross-sectional and multicenter study conducted among 5007 consecutive patients aged ≥18 years. The study population consisted of outpatients on aspirin treatment (80-300 mg). The patient data were obtained from 30 different cardiology clinics of 14 cities from all over Turkey. In this subgroup analysis, patients were divided into 2 groups: the hypertensive group (n=3467, 69.3%) and the group without hypertension (n=1540, 30.7%) according to the 2018 European Society of Cardiology/ European Society of Hypertension Guidelines for the Management of Arterial Hypertension. RESULTS: Aspirin use for primary prevention was higher in patients with hypertension compared to patients without hypertension [328 (21.3%); 1046 (30.2%); P < .001]. Treatment with a dose of 150 mg aspirin (n=172, 5%) was mostly preferred by internists for hypertensive patients (n =226, 6.5%); however, a daily dose of 80-100 mg aspirin therapy (n=1457, 94.6%) was mostly prescribed by cardiologists (n=1347, 87.5%) for patients without hypertension. CONCLUSION: Aspirin was found to be used commonly among patients with hypertension for primary prevention despite the current European Society of Cardiology Arterial Hypertension Guideline not recommending aspirin for primary prevention in patients with hypertension.

INTRODUCTION: Pericardiocentesis is an invasive procedure performed to drain fluid from the pericardial cavity. AIM: We investigated the quality of videos about pericardiocentesis on YouTube and analysed their reliability and teaching properties, in the covid 19 period when online education has come to the fore. MATERIAL AND METHODS: We searched YouTube using the terms "pericardiocentesis, cardiac tamponade, pericardial effusion, pericardial effusion drainage, pericardial tamponade" for uploaded videos. We scored every video according to the questions we prepared using the guidelines about pericardiocentesis. We used the HONcode score, GQS score, and RELIABILITY score to assess the quality of videos. Two physicians independently and blindly classified videos as useful or misleading and rated them. RESULTS: A total of 168 videos were examined. After the application of exclusion criteria, 38 videos were evaluated. The pericardiocentesis checklist average score was 10.45 ±2.56. According to sources of videos, the average score for university or research hospital videos was 13.1 ±1.5, and videos whose source could not be identified had an average score of 7.5 ±2.0. According to the level of HONcode, 17 (44.7%) videos were low quality; according to GQS score, 8 (21.1%) videos were poor quality. The quality of university hospital uploads (ß-coefficient 3.960, p-value 0.004) were higher and statistically significant than other upload centres. CONCLUSIONS: The educational value of pericardiocentesis videos on YouTube are low. It is recommended that doctors and patients be aware of and adopt the developing technology, and they should prefer videos uploaded from university hospitals and educational hospitals.
RESUMEN
BACKGROUND: Grading the severity of aortic regurgitation (AR) is very important for clinical follow-up. In AR, left atrial (LA) mechanics can be affected in time and LA strain variations can be illuminating for the grading of AR. The purpose of this study is to determine whether the LA strain parameters are associated with the severity of AR or not. METHODOLOGY: Sixty-four consecutive patients with AR were included in this study. Patients divided into three groups as mild (n: 22), moderate (n: 15), or severe (n: 27). All patients' LA strain measurements were performed and results were compared between groups. RESULTS: Between the groups, LA reservoir (LA-Res) in the mild, moderate, and severe AR groups was 42.0 ± 18.0, 41.4 ± 14.8, and 29.2 ± 6.0, respectively (P: 0.002) and LA pump in the mild, moderate, and severe AR groups was 21.2 ± 8.7, 19.3 ± 7.4, and 13.1 ± 4.4, respectively (P < 0.001), different, while no difference was noticed on LA SRs, LA SRe, and LA SRa. CONCLUSION: This study showed that LA-Res and LA pump parameters of the patients with severe AR significantly decreased compared to those of the mild and moderate AR group. The grading of the LA mechanics in patients with chronic AR might provide a supplementary contribution to the present parameters in the grading of AR.
RESUMEN
OBJECTIVE: Mitral valve prolapse (MVP) is a heart valve anomaly that affects a considerable segment of the population. Studies of patients with isolated MVP have shown that aortic distensibility decreased as the aortic diameter increased. The aim of this study was to compare evaluations of aortic distensibility in MVP patients using both applanation tonometry and the conventional echocardiographic examination. METHODS: A total of 36 consecutive patients with MVP (16 male and 20 female) and 23 healthy controls (11 male and 12 female) were included in this study. The difference in aortic diameter and distensibility was examined using echocardiography and pulse wave velocity (PWV) was measured with applanation tonometry. RESULTS: According to the echocardiographic measurements, the aortic distensibility was lower in the MVP patients than in the control group (6.2±4.0 cm².dyn⻹.10â»6 vs. 10.0±5.2 cm². dyn⻹.10â»6; p=0.02). The PWV measured with applanation tonometry was significantly higher in the MVP patients than in the control group (9.0±2.4 m/s vs. 7.2±1.4 m/s; p=0.006). CONCLUSION: The results of this study showed that aortic distensibility was reduced in patients with isolated MVP compared with a healthy control group. There was a moderate negative correlation between the results of both methods.

INTRODUCTION: Periprocedural myocardial necrosis, which can range from a low level elevation of cardiac biomarkers to a large myocardial infarction (MI), is a common complication after percutaneous coronary intervention (PCI). AIM: We hypothesized that insulin-like growth factor-1 (IGF-1) levels may play a protective role in myocardial injury after coronary stent placement and aimed to investigate the relationship between IGF-1 levels and plaque characteristics assessed by optical coherence tomography (OCT). MATERIAL AND METHODS: Between May 2015 and December 2015 we prospectively enrolled 74 patients with stable angina pectoris in whom single de novo coronary artery stenosis was present. PCI was performed according to standard methods. OCT was applied to all patients. TnT was analyzed at admission, before PCI and at 6, 12, 24 and 48 h after PCI. Serum IGF-1 was measured prior to PCI. RESULTS: A total of 25 (33.7%) patients had periprocedural myocardial injury or type 4a myocardial infarction, and 49 (66.2%) patients had no events. IGF-1 level and reference intimal thickness, medial thickness, and plaque fibrous cap thickness in OCT had strong correlations (r = 0.88, 0.80 and 0.88 respectively, p < 0.001). IGF-1 was an independent predictor of periprocedural myocardial injury or type 4a MI in univariate (OR = 0.929, 95% CI: 0.895-0.964, p < 0.001) and multivariate regression analysis (OR = 0.757, 95% CI: 0.575-0.998, p = 0.04). Based on ROC analysis, the best cut-off value of IGF-1 for predicting periprocedural myocardial injury or type 4a myocardial infarction was 144.5 ng/ml, with a maximum sensitivity of 88% and specificity of 77.6% (AUC = 0.80, 95% CI: 0.69-0.88, p < 0.0001). CONCLUSIONS: The results from this study indicate that low IGF-1 levels are associated with plaque instability assessed by OCT. Low IGF-1 levels may identify patients who are at increased risk for periprocedural myocardial injury/infarction.
RESUMEN
OBJECTIVE: The aim of this study was to describe the current status of aspirin use and the demographic characteristics of patients on aspirin for primary and secondary prevention of cardiovascular diseases. METHODS: The Appropriateness of Aspirin Use in Medical Outpatients: A Multicenter, Observational Study (ASSOS) trial was a multicenter, cross-sectional, and observational study conducted in Turkey. The study was planned to include 5000 patients from 14 cities in Turkey. The data were collected at one visit, and the current clinical practice regarding aspirin use was evaluated (ClinicalTrials.gov number NCT03387384). RESULTS: The study enrolled all consecutive patients who were admitted to the outpatient cardiology clinics from March 2018 until June 2018. Patients should be at least 18 years old, have signed written informed consent, and on aspirin (80-325 mg) therapy within the last 30 days. Cardiologists from the hospital participates in the study. Patients were divided into 2 categories according to presence or absence of atherosclerotic cardiovascular disease, namely secondary prevention group and primary prevention group, respectively. The appropriate use of aspirin in the primary and secondary prevention groups was assessed according to the European Society of Cardiology guidelines and US Preventive Services Task Force. The patients' gastrointestinal bleeding risk factors and colorectal cancer risk were evaluated. CONCLUSION: The ASSOS registry will be the most comprehensive and largest study in Turkey evaluating the appropriateness of aspirin use. The results of this study help understand the potential misuse of aspirin in a real-world setting.

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 ≥50âmL/min, urban living, existing dabigatran treatment, and HAS-BLED score of <3, whereas that of OT were creatinine clearance <50âmL/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.
