RESUMO
Objectives: Predictive risk scores have a significant impact on patient selection and assessing the likelihood of complications following interventions in patients with severe aortic stenosis (AS). This study aims to explore the utility of machine learning (ML) techniques in predicting 30-day major adverse cardiac events (MACE) by analyzing parameters, including the Global Registry of Acute Coronary Events (GRACE) score. Methods: This retrospective, multi-center, observational study enrolled 453 consecutive patients diagnosed with severe AS who underwent transcatheter aortic valve implantation (TAVI) from April 2020 to January 2023. The primary outcome was defined as a composition of MACE comprising periprocedural myocardial infarction (MI), cerebrovascular events (CVE), and all-cause mortality during the 1-month follow-up period after the procedure. Conventional binomial logistic regression and ML models were utilized and compared for prediction purposes. Results: The study population had a mean age of 76.1, with 40.8% being male. The primary endpoint was observed in 7.5% of cases. Among the individual components of the primary endpoint, the rates of all-cause mortality, MI, and CVE were reported as 4.2%, 2.4%, and 1.9%, respectively. The ML-based Extreme Gradient Boosting (XGBoost) model with the GRACE score demonstrated superior discriminative performance in predicting the primary endpoint, compared to both the ML model without the GRACE score and the conventional regression model [Area Under the Curve (AUC)= 0.98 (0.91-0.99), AUC= 0,87 (0.80-0.98), AUC= 0.84 (0.79-0.96)]. Conclusion: ML techniques hold the potential to enhance outcomes in clinical practice, especially when utilized alongside established clinical tools such as the GRACE score.
RESUMO
BACKGROUND: The role of speckle tracking in the assessment of right atrial (RA) deformation parameters has not been investigated yet. The purpose of this article is to establish the effects of normal pregnancy on RA mechanical changes obtained by 2-dimensional speckle-tracking echocardiography. METHODOLOGY: A total of 49 healthy pregnant women were included in the study. All participants were followed for each trimester and postpartum period, encompassing standard assessments of both RA and ventricular functions, as well as measurements of RA global peak atrial longitudinal strain (RA-Global-PALS) and RA global peak atrial contraction strain (RA-Global-PACS). Additionally, the RA segments were individually evaluated with respect to strain parameters. RESULTS: During pregnancy, the increased volume load resulted in elevated RA reservoir function, as indicated by RA-Global-PALS, and increased contraction parameter, as indicated by RA-Global-PACS. These changes were within physiological limits and reversible. Segmental analysis of the right atrium showed similar findings for regional PACS and PALS parameters. CONCLUSION: In this study, we established normal RA deformation parameters for healthy pregnancies. These data will aid in discerning various measures of RA phasic function in cardiovascular and systemic conditions among normal pregnant women. Moreover, they may offer insights into potential cardiac pathologies that may arise during the pregnancy.
RESUMO
The relationship between white coat hypertension (WCH) and anxiety remains not fully elucidated. This study aims to investigate the correlation between WCH and Templer's Death Anxiety Scale (T-DAS) questionnaire. Asymptomatic individuals with a familial history of sudden cardiac death or acute myocardial infarction within the last year, who presented at our cardiology outpatient clinic, were enrolled in this prospective, single-center, cross-sectional study. Among those with elevated blood pressure in the outpatient clinic setting, participants were categorized into normotensive and WCH groups through 24-hour ambulatory blood pressure monitoring. Demographic features, laboratory parameters, and T-DAS scores were documented. Logistic regression and sensitivity analyses were conducted to ascertain WCH occurrence. Among 324 consecutive participants, 90 were diagnosed with WCH. T-DAS scores were significantly elevated in the WCH subgroup, particularly among those seeking early medical attention following bereavement. Multivariable logistic regression highlighted gender, BMI, heart rate, T-DAS, and admission time as independent correlates of WCH. Significantly, T-DAS exhibited the third most substantial contribution to the regression analysis, following admission time and heart rate. The multivariable logistic regression analysis incorporating T-DAS exhibited high robustness, discrimination, fit, and calibration, with a Brier score of 0.106, adjusted R2 of 0.576, and C-statistic of 0.905 (95% CI: 0.871-0.940, p < 0.001). T-DAS, with a threshold of >8, demonstrated 48% sensitivity and 90% specificity in detecting WCH. Additionally, decision curve analysis verified that the model including T-DAS offers a net benefit in detecting WCH. This study unveils a potential association between WCH and death anxiety.

OBJECTIVE: Due to the conflict in Syria since 2011, more than 3.5 million Syrian citizens reside in Türkiye. Because Syrian patients were underrepresented in previous studies on percutaneous coronary intervention (PCI) outcomes, we aimed to analyze the severity of coronary artery disease and in-hospital outcomes of PCI in this population. METHODS: We retrospectively analyzed 142 Syrian patients who underwent PCI at our center between June 2020 and October 2022 and compared the data with that of age- and sex-matched Turkish patients (n = 271) who also underwent PCI. We assessed comorbidities, coronary anatomy features, procedural complications, and in-hospital cardiovascular outcomes (Major Adverse Cardiac and Cerebrovascular Events, MACCE). RESULTS: The mean age of the study population was 57 ± 12 years, with 15% being female. Clinical indication and coronary anatomy features did not differ between the groups. However, the Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score was higher in Syrian patients compared to Turkish patients (16 [11-22] vs. 12 [8-20]; P < 0.001). Complex PCI rates, in-hospital bleeding and contrast nephropathy were similar in both groups. MACCE was comparable between Syrian and Turkish patients (13 [4.8%] vs. 13 [9.2%], P = 0.083). CONCLUSION: Comparable MACCE rates were observed in both ethnic groups undergoing PCI, despite a higher SYNTAX score in Syrian patients. Future research should investigate whether similar in-hospital MACCE rates are observed in other regions of Türkiye and whether long-term cardiovascular outcomes differ between Turkish and Syrian patients.

This study aimed to explore the potential association between the triglyceride-glucose index (TyG) and the atherogenic index of plasma (AIP)-both considered surrogate markers for atherosclerosis-and major adverse cardiovascular events (MACEs) in patients diagnosed with chronic coronary syndrome (CCS). We conducted a retrospective analysis, encompassing 715 consecutive patients with intermediate CCS risk, who presented at the outpatient clinic between June 2020 and August 2022. MACEs included non-fatal myocardial infarction, hospitalization for heart failure, cerebrovascular events, non-cardiac mortality, and cardiac mortality. The primary outcome was the composite occurrence of MACEs during the follow-up period. For time-to-event analysis of the primary outcome, we employed Kaplan-Meier plots and Cox proportional hazard models. The median age of the overall study population was 55 years, with a median follow-up duration of 17 months. Multivariate Cox regression analysis identified age, hypertension, Coronary Artery Disease-Reporting and Data System score, and TyG index as independent predictors of the primary outcome. Notably, individuals with high TyG levels exhibited a significantly higher primary outcome rate compared to those with low TyG levels (18.7% vs. 3.8%, p < 0.001). Similarly, patients with elevated TyG values demonstrated statistically higher rates of cerebrovascular events, hospitalizations for heart failure, non-fatal myocardial infarctions, non-cardiac mortality, and cardiac mortality. These findings suggest that TyG may serve as a predictive marker for adverse cardiovascular outcomes in patients with CCS.
RESUMO
AIM: Coronary slow flow phenomenon (CSFP) detected on coronary angiography (CA) has been related to poor prognosis. We sought to examine the relationship between thromboembolic risk scores, routinely used in cardiology practice, and CSFP. METHODS: This single-center, retrospective, case-control study comprised 505 individuals suffering from angina and had verified ischemia between January 2021 and January 2022. Demographic and laboratory parameters were obtained from the hospital database. The following risk scores were calculated; CHA2DS2-VASc, M-CHA2DS2-VASc, CHA2DS2-VASc-HS, R2-CHA2DS2-VASc, M-R2-CHA2DS2-VASc, ATRIA, M-ATRIA, M-ATRIA-HSV. The overall population was divided into two groups; coronary slow flow and coronary normal flow. Multivariable logistic regression was performed to compare risk scores between patients with and without CSFP. Pairwise comparisons were then undertaken to test performance in determining CSFP. RESULTS: The mean age was 51.7 ± 10.7 years, of whom 63.2% were male. CSFP was detected in 222 patients. Those with CSFP had higher rates of male gender, diabetes, smoking, hyperlipidemia, and vascular disease. All scores were higher in CSFP patients. Multivariable logistic regression analysis found that CHA2DS2-VASc-HS score was the most powerful determinant of CSFP among all risk schemes (for each one-point increase in score OR = 1.90, p < 0.001; for score of 2-3 OR = 5.20, p < 0.001; for score of >4 OR = 13.89, p < 0.001). Also, the CHA2DS2-VASc-HS score provided the best discriminative performance, with a cut-off value of ≥2 in identifying CSFP (AUC = 0.759, p < 0.001). CONCLUSION: We showed that thromboembolic risk scores may be associated with CSFP in patients with non-obstructive coronary architecture who underwent CA. The CHA2DS2-VASc-HS score had the best discriminative ability.

Aim: This work was designed to investigate the relationship between cardiac outcomes and Naples Prognostic Score (NPS) among heart failure (HF) patients. Materials & methods: This retrospective observational study enrolled 298 consecutive individuals hospitalized for New York Heart Association class 3-4 HF. The primary outcome was all-cause mortality. Secondary outcomes were rehospitalization and in-hospital death. Results: The high NPS group had a statistically greater rate of all-cause mortality (p < 0.001). In Cox regression analysis, integrating NPS considerably improved the performance of the full model over the baseline model (adjusted hazard ratio = 2.28; p = 0.004). Based on time-dependent receiver operating characteristic curve analysis, the NPS model outperformed the baseline and CONUT score models in discriminatory power in predicting the probability of survival. Conclusion: NPS was associated with short- and midterm mortality as well as rehospitalization.
Heart failure is a serious condition that affects millions of individuals around the world. This study was designed to investigate whether there is a relationship between Naples Prognostic Score (NPS) and worse outcomes in heart failure patients. A total of 298 patients with advanced heart failure were included in the study. Patients with a high NPS are more likely to pass away and need to be readmitted to the hospital. NPS also predicted survival more accurately than some other variables at an average of 15 months follow-up. In conclusion, NPS was found to be useful in predicting short- and medium-term mortality and readmissions in patients with advanced heart failure.

INTRODUCTION: Up to one-third of patients indicated for transcatheter aortic valve implantation (TAVI) may be unsuitable for transfemoral TAVI (TF-TAVI) according to manufacturers' recommendations and numerous professional societies. OBJECTIVE: This study aimed to investigate the predictive value of manufacturers' guidelines for major vascular access site complications using the Perclose ProGlide device. METHODS: Among 208 patients undergoing TF-TAVI, 144 patients (69.2%) were deemed eligible for TF-TAVI according to the manufacturer's instructions. A minimal lumen diameter (MLD) of the femoral artery below the manufacturer's specified limits and/or the presence of circumferential calcification were the reasons for ineligibility. Calcium score (CS), sheath-to-femoral artery ratio (SFAR) and MLD were estimated from computed tomography imaging. Vascular complications (VCs) (defined according to VARC-2 criteria) were retrospectively compared. RESULTS: Patients in the ineligible group had higher SFAR (1.13±0.15 vs. 0.88±0.107, p<0.001) and CS (1.66±0.99 vs. 1.24±0.73; p=0.003), and significantly lower MLD (7.72±1.03 vs. 6.31±0.96 mm; p<0.001) compared to the eligible group. Major (6.3% vs. 12.3%, p=0.13) and minor VCs (10.4% vs. 15.6%, p=0.29) were similar in the eligible and ineligible groups. The ineligible group had higher rates of rupture (0.7% vs. 6.3%; p=0.03). SFAR was the only independent predictor of major VCs (OR 469.1, 95% CI 4.95-44466.57, p=0.008). CONCLUSION: The TAVI team should not decide whether the patient is suitable for a femoral approach based solely on the manufacturer's criteria, and should incorporate additional factors that could be predictive of major VCs.

BACKGROUND: The failure rate of vascular closure devices remains a significant cause of major vascular complications in contemporary transcatheter aortic valve implantation practice. METHODS: This research aimed to evaluate use of the Angio-Seal device in a bailout context in the setting of incomplete hemostasis following use of dual Perclose ProGlide devices in patients undergoing transfemoral transcatheter aortic valve implantation. A total of 185 patients undergoing transfemoral transcatheter aortic valve implantation with either dual Per-close ProGlide (n = 139) or a combination of dual Perclose ProGlide and Angio-Seal (n = 46) were retrospectively analyzed. The baseline, procedural characteristics, and all outcomes (defined according to Valve Academic Research Consortium-2 criteria) were compared. RESULTS: No significant differences were seen between the dual Perclose ProGlide vs dual Perclose ProGlide+Angio-Seal groups with regard to the in-hospital Valve Academic Research Consortium-2 primary end points of major vascular complications (n = 13 [9.4%] vs n = 2 [4.3%]; P = .36), minor vascular complications (n = 13 [9.4%] vs n = 8 [14.7%]; P = .14), major bleeding (n = 16 [11.5%] vs n = 2 [4.3%]; P = .25), and minor bleeding (n = 9 [6.5%] vs n = 5 [10.9%]; P = .34), with higher rates of hematoma in the dual Perclose ProGlide+Angio-Seal group (n = 4 [2.9%] vs n = 5 [10.9%]; P = .044). CONCLUSION: Finding from the current study suggest that adjunctive Angio-Seal deployment may be feasible and safe, especially in patients with incomplete hemostasis following dual Perclose ProGlide use, and can be an optimal "bailout" procedure.

OBJECTIVE: Vascular complications (VCs) contribute to increased morbidity and mortality in patients who have undergone transcatheter aortic valve implantation (TAVI); however, studies on their incidence and predictors show conflicting results. In this study, we sought to assess the incidence, impact, and predictors of VCs in transfemoral (TF) TAVI and also investigated the predictive role of manufacturer's size charts and a new predictor modified sheath-to-femoral artery ratio. METHODS: A total of 223 patients undergoing TF-TAVI were categorized into 2 groups. The patients were divided as eligible and ineligible according to the manufacturer's guidelines (MG), and the same patient cohort was dichotomized into eligible and ineligible on the basis of sheath-to-femoral artery ratio (SFAR) value of less than or greater than or equal to modified SFAR (md-SFAR). VCs (defined according to the Valve Academic Research Consortium II criteria) were retrospectively compared. RESULTS: According to the manufacturer's size charts, 65 patients were unsuitable; however, 35 patients were ineligible for TF-TAVI per the md-SFAR criteria. Although VCs occurred in 42 (18.8%) patients, 17 (27.7%) of those patients were classified as ineligible according to MG, whereas 14 (41.2%) were classified as ineligible in the md-SFAR group. In a multiple logistic regression analysis that included md-SFAR, MG, SFAR ≥1.05, peripheral artery disease, and minimum iliofemoral artery diameter, only md-SFAR was the independent predictor of VCs (odds ratio=3.71, 95% confidence interval=1.13-12.53, p=0.031). CONCLUSION: According to our results, md-SFAR might provide better patient selection to prevent VCs and improve outcomes in TF-TAVI procedures.

INTRODUCTION: The non-O phenotype of the ABO genotype has been linked with an increased risk of cardiovascular disease. Atrioventricular (AV) block (AVB) is defined as retardation or cessation in the route of an electrical impulse passing from the atria to the ventricles because of an anatomical or functional disruption in the conduction system. We aimed to interpret the association between blood group status and high-grade atrioventricular block (HAVB). MATERIAL AND METHODS: This study was implemented as a retrospective review of the recorded data of patients diagnosed with high-grade AV block and a control group. The study population consisted of 640 patients with HAVB and 570 control subjects. RESULTS: Presence of non-O blood group (p < 0.001) was significantly more prevalent in HAVB patients than in the control subjects. Blood group type was the sole independent predictor of HAVB in multiple regression analysis (p < 0.001, OR = 1.35, 95% CI: 1.08-1.57). Also, third-degree AVB had a higher incidence in the non-O blood subgroup and also non-O blood group was a predictor of third-degree AVB (p < 0.001, OR = 1.39, 95% CI: 1.13-1.69). The incidence of HAVB did not distinguish between the two Rh (D) groups. Rh (D) status did not have an impact on HAVB. CONCLUSIONS: This is the first study that has evaluated the potential relationship between HAVB and ABO blood groups. The main finding of this report is that patients with non-O blood group types have a higher risk for development of HAVB compared with O blood group patients.
RESUMO
OBJECTIVE: We aim to study left atrial (LA) strains in patients with hypertensive response to exercise (HRE) and determine their usefulness in predicting masked hypertension (HT). METHODS: Ninety-eight normotensive patients who had HRE were included and were divided into two groups after masked HT had been diagnosed by ambulatory blood pressure monitoring. Conventional echocardiographic parameters and two-dimensional speckle-tracking echocardiography-based LA strain parameters were compared. RESULTS: Patients with masked HT have higher left ventricle mass index (LVMI) (88.1±11.3 vs. 82.5±8.7 g/m, P<0.05), left atrium maximum volume index (LAVI) (34.5±5.1 vs. 30.2±5.6 ml/m, P<0.001), lower global longitudinal LA strain during ventricular systole (GLAs-res) (32.5±8.9 vs. 40.2±9.1%, P<0.001), and lower global longitudinal LA strain during late diastole (GLAs-pump) (15.8±4.1 vs. 18.1±5.8%, P<0.05). In univariate analysis, a good negative correlation was found between GLAs-res versus LAVI (r=-0.451, P<0.001), GLAs-res versus LVMI (r=-0.457, P<0.001) and a moderate negative correlation was present between GLAs-pump versus LAVI (r=-0.317, P<0.001) and GLAs-pump versus LVMI (r=-0.288, P<0.05). GLAs-res and LAVI were found to be independent predictors of masked HT. Receiver-operating characteristic analysis was carried out. Area under the curve to predict masked HT was 0.729 (95% confidence interval: 0.623-0.832, P<0.001). GLAs-res less than 33.1% predicted masked HT with 73% sensitivity and 61.5% specificity. CONCLUSION: LA strain parameters were impaired in patients with masked HT and can be used to predict the presence of masked HT in patients with HRE.

OBJECTIVES: The aim of this study was to assess whether NLR levels are associated with echocardiographic parameters, New York Heart Association (NYHA) functional class, or B- type natriuretic peptide (BNP) levels in patients with idiopathic dilated cardiomyopathy (DCM). DESIGN: Eighty-seven patients with idiopathic DCM were included prospectively from 2009 to 2014. Patients with acute decompensated heart failure and conditions that alter the total or differential white blood cell counts were excluded. Blood samples were collected before echocardiographic investigation on admission. RESULTS: There was a statistically significant correlation between neutrophil/lymphocyte ratio (NLR) and NYHA functional class (r = 0.68, p < 0.001), BNP levels (r = 0.61, p < 0.001) and various echocardiographic parameters. NLR was significantly higher in patients in NYHA functional class III or IV (n = 39) than among those categorized as NYHA class I or II (n = 48), (3.3 ± 1.0 vs 2.1 ± 0.6; p < 0.001). The NLR cutoff value predicting severe chronic HF was 2.25 with 82% sensitivity and 65% specificity (p < 0.001). On multivariate linear regression analysis NLR (p = 0.025), left ventricular end-diastolic volume (p = 0.041) and left atrial volume index (LAVI) (p = 0.001) were found to be independent positive predictors of BNP levels. CONCLUSION: Neutrophil/Lymphocyte ratio is associated with the severity of chronic heart failure in patients with idiopathic DCM.

Mitral valve aneurysms (MVAs) are rarely encountered in echocardiography laboratories. Although they are commonly associated with endocarditis of the aortic valve, various mechanisms have been suggested for the etiopathogenesis of MVAs associated with non-infectious conditions. 5,887 patients who underwent transesophageal echocardiography (TEE) between 2007 and 2012 were evaluated retrospectively for MVA. Mitral valve aneurysm is defined as a localized saccular bulging of the mitral leaflet towards the left atrium with systolic expansion and diastolic collapse. The color flow Doppler image of a perforation was described as a high-velocity turbulent jet traversing a valve leaflet in systole. We found that 12 of 5,887 patients (0.204 %) had MVA in TEE examinations. The mean age of patients with MVA was 53 years (range 21-80 years), including four females and eight males. Nine patients presented with symptoms of endocarditis. On TEE, aneurysms were located in the anterior mitral leaflet in 11 patients, and in the posterior mitral leaflet in one patient. Eight patients had severe, three had moderate, and one had trace mitral regurgitation. Of the nine patients with perforated leaflets, eight patients had severe and one patient had moderate mitral regurgitation. Aortic regurgitation was present in nine patients, being severe in three, moderate in two, mild in two, and trace in two patients. Two patients without severe mitral regurgitation were followed-up conservatively, while nine patients underwent surgery. Two patients died from septic shock, one in the postoperative period and the other one prior to surgery. Although MVAs occur during the course of aortic valve endocarditis and, in particular, due to aortic regurgitation jet, it should be borne in mind that they may develop as an isolated valvular pathology and may be misdiagnosed as chordal rupture, other cardiac masses, or vegetation. Thus, MVAs may not be so infrequent as they are thought; they may justify to be considered in the differential diagnosis of masses seen on the mitral valve on echocardiographic examination.
