RESUMEN
OBJECTIVE: This study aims to assess the predictive value of the Systemic Immune Inflammation Index (SII) in determining in-stent restenosis (ISR) likelihood in patients with acute coronary syndrome (ACS) who have undergone percutaneous coronary intervention (PCI). METHODS: The study enrolled 903 ACS patients undergoing PCI, categorized into ISR (+) and ISR (-) groups based on control coronary angiography results. Demographic, clinical, laboratory, and angiographic-procedural characteristics were systematically compared. RESULTS: The ISR (+) group encompassed 264 individuals (29.2%), while the ISR (-) group comprised 639 individuals (70.8%). Patients had a mean age of 55.8â ±â 10.2 years, with 69% being male. The ISR (+) group had higher diabetes and smoking prevalence and notably larger stent dimensions. Lab parameters showed significantly elevated creatinine, total cholesterol, red cell distribution width, white blood cell and neutrophil counts, SII index and C-reactive protein (CRP) in the ISR (+) group, while lymphocyte levels were lower. Binary logistic regression identified stent diameter (odds ratio [OR]: 0.598, 95% confidence interval [CI]: 0.383-0.935; P â =â 0.024), stent length (OR: 1.166, 95% CI: 1.132-1.200; P â <â 0.001), creatinine (OR: 0.366, 95% CI: 0.166-0.771; P â =â 0.003), CRP (OR: 1.075, 95% CI: 1.042-1.110; P â =â 0.031), and SII index (OR: 1.014, 95% CI: 1.001-1.023; P â <â 0.001) as independent ISR predictors. CONCLUSION: The SII index exhibits potential as a predictive marker for ISR in ACS patients post-PCI, indicating systemic inflammation and heightened restenosis risk. Integrating the SII index into risk models could identify high-risk patients for targeted interventions.

BACKGROUND: Heart failure with preserved ejection fraction is a complex and heterogeneous clinical syndrome, poses significant diagnostic challenges. The HFA-PEFF [Heart Failure Association of ESC diagnostic algorithm, P (Pretest Assessment), E (Echocardiographic and Natriuretic Peptide score), F1 (Functional testing in Case of Uncertainty), F2 (Final Aetiology)] and H2FPEF [Heavy (BMI>30 kg/m2), Hypertensive (use of ≥2 antihypertensive medications), atrial Fibrillation (paroxysmal or persistent), Pulmonary hypertension (Doppler Echocardiographic estimated Pulmonary Artery Systolic Pressure >35 mm Hg), Elderly (age >60 years), Filling pressure (Doppler Echocardiographic E/e' >9)] scoring systems were developed to aid in diagnosing heart failure with preserved ejection fraction. This study aimed to assess the concordance and clinical accuracy of these scoring systems in the 'A comPrehensive, ObservationaL registry of heart faiLure with mildly reduced and preserved ejection fractiON' cohort. METHODS: A comPrehensive, ObservationaL registry of heart faiLure with mildly reduced and preserved ejection fractiON study was conducted as a multicenter, cross-sectional, and observational study; to evaluate a group of Heart failure with mildly reduced ejection fraction and heart failure with preserved ejection fraction patients who were seen by cardiologists in 13 participating centers across 12 cities in Türkiye. RESULTS: The study enrolled 819 patients with heart failure with preserved ejection fraction, with high probability heart failure with preserved ejection fraction rates of 40% and 26% for HFA-PEFF and H2FPEF scorings, respectively. The concordance between the 2 scoring systems was found to be low (Kendall's taub correlation coefficient of 0.242, P < .001). The diagnostic performance of both scoring systems was evaluated, revealing differences in their approach and ability to accurately identify heart failure with preserved ejection fraction patients. CONCLUSION: The low concordance between the HFA-PEFF and H2FPEF scoring systems underscores the ongoing challenge of accurately diagnosing and managing patients with heart failure with preserved ejection fraction. Clinicians should be aware of the strengths and limitations of each scoring system and use them in conjunction with other clinical and laboratory findings to arrive at an accurate diagnosis. Future research should focus on identifying additional diagnostic factors, developing more accurate and comprehensive diagnostic algorithms, and investigating alternative methods of diagnosis or stratification of patients based on different clinical characteristics.

BACKGROUND: Left atrial (LA) strain is a robust measure of LA function and is a useful parameter to assess left ventricular filling pressure. While initially considered as a "load-independent" parameter of LA function, later studies have found that acute changes in LA preload may affect LA reservoir and contractile strains. Acute alterations in blood pressure (BP) induces a change in left ventricular (LV) filling pressure without imposing a volume load, thus providing an opportunity to assess the effects of the change in LA afterload on LA mechanics. This study aims to understand the effect of acute BP changes on LA strain. METHODS: A total of 40 patients admitted to the emergency department with hypertensive urgency were included. All patients underwent a comprehensive echocardiographic examination including measurement of LA reservoir, conduit and contractile strains. A repeat set of measurements were obtained after BP lowering. RESULTS: Average drop in mean BP following intervention was 18.1 ± 5.4%. LV end-systolic and end-diastolic volumes, as well as maximum and minimum LA volumes were decreased significantly after BP reduction. The absolute increases in reservoir and contractile strains were 2.3 ± 4.7% (7.9% ± 13.8% relative to baseline) and 2.5 ± 3.3% (13.5 ± 19.0% relative to baseline), respectively, with both changes being statistically significant (p = 0.003 for reservoir and p < 0.001 for contractile strains). There were no significant changes in conduit strain after BP intervention (p = 0.79). The change in both LA reservoir and contractile strains were more evident in those with a previous diagnosis of hypertension and those with a smaller degree of change in mean BP after intervention. CONCLUSION: In patients with an acute hypertension, lowering BP leads to an acute improvement in LA reservoir and contractile strains. Thus, acute changes in systemic BP should be considered when LA mechanics are evaluated.

OBJECTIVE: The aim of the present study was to investigate the association between the mean corrected thrombolysis in myocardial frame count and major adverse cardiovascular events in patients with the coronary slow-flow phenomenon. METHODS: A total of 98 patients with coronary slow-flow phenomenon who met inclusion cri- teria from 2015 to 2020 were retrospectively included in the analysis. The patients were ranked according to their mean corrected thrombolysis in myocardial frame count values and were divided into quartiles based on those. Group 1 consisted of patients who had a mean corrected thrombolysis in myocardial frame count value >36.68 (third quartile), while group 2 consisted of patients who had a mean corrected thrombolysis in myocardial frame count value ≤36.68 (first quartile+second quartile). Mortality and non-fatal cardiovascular complications were compared between the groups. RESULTS: Mean follow-up duration was 3.93 ± 1.50 years. Recurrent chest pain and major adverse cardiovascular events increased in group 1 compared to group 2 (P ≤ .001, P ≤ .001, respectively). Hypertension (odds ratio 2.627, P=.033), hyperlipidemia (odds ratio 2.469, P = .028) and mean corrected thrombolysis in myocardial frame count (odds ratio 1.106, P = .002) were independent predictors of recurrent chest pain according to Cox regression analysis. Although older age (odds ratio 1.125, P=.011), hypertension (odds ratio 6.081, P=.026), hyperlipidemia (odds ratio 12.308, P = 0.019), and mean corrected thrombolysis in myocardial frame count (odds ratio 1.476, P = .001) were found to be significantly related with major adverse cardiovascular events in patients with coronary slow-flow phenomenon, only mean corrected thrombolysis in myocardial frame count (odds ratio 1.161, P = .021) was an indepen- dent predictor of major adverse cardiovascular events in Cox regression analysis. CONCLUSION: Higher mean corrected thrombolysis in myocardial frame count could predict major adverse cardiovascular events in patients with the coronary slow-flow phenomenon.

AIMS: The frontal QRS-T (fQRST) angle is associated with worse cardiovascular outcome. The study aimed to assess the effect of reverse dipping pattern on f(QRST) angle in newly diagnosed masked hypertensive (MH) patients. MATERIALS AND METHODS: Newly diagnosed 244 consecutive MH patients were included. According to dipping pattern, patients were grouped into three: dipper (n = 114), non-dipper (n = 106), and reverse dipper (n = 24) patterns. The f(QRST) angle, QT and corrected QT interval, and QT dispersion were measured from the 12-lead surface electrocardiogram and compared between groups. RESULTS: Of all, 51.2% (n = 125) were male. No gender difference was observed. Reverse dipper MH group had a significantly higher f(QRST) angle than the non-dipper and dipper MH groups (77.9 ± 8.6 vs. 32.4 ± 18.8 and 26.0 ± 18.5, respectively, p < .001). The cutoff value for f(QRST) angle of 51 predicts reverse dipping pattern (AUC: 0.84; 95% CI: 0.77-0.90; p < .001), with a sensitivity of 83% and a specificity of 78%. CONCLUSION: This study revealed that f(QRST) angle is gradually increased starting from the dipper, non-dipper to reverse dipper masked hypertensives. The f(QRST) angle appears as an easy marker for the detection and risk stratification of hypertensive patients.

BACKGROUND: The heart rate variability (HRV) is a non-invasive, objective and validated method for the assessment of autonomic nervous system. Although acute manifestations of COVID-19 were widely researched, long-term sequela of COVID-19 are still unknown. This study aimed to analyze autonomic function using HRV indices in the post-COVID period that may have a potential to enlighten symptoms of COVID long-haulers. METHODS: The 24-h ambulatory electrocardiography (ECG) recordings obtained >12 weeks after the diagnosis of COVID-19 were compared with age-gender-matched healthy controls. Patients who used drugs or had comorbidities that affect HRV and who were hospitalized with severe COVID-19 were excluded from the study. RESULTS: Time domain indices of HRV analysis (standard deviation of normal RR intervals in 24 h (SDNN 24 h) and root mean square of successive RR interval differences (RMSSD)) were significantly higher in post-COVID patients (p < 0.05 for all). Among frequency domain indices, high frequency and low frequency/high frequency ratio was significantly higher in post-COVID patients (p = 0.037 and p = 0.010, respectively). SDNN >60 ms [36 (60.0%) vs. 12 (36.4%), p = 0.028)] and RMSSD >40 ms [31 (51.7%) vs. 7 (21.2%), p = 0.003)] were more prevalent in post-COVID patients. Logistic regression models were created to evaluate parasympathetic overtone in terms of SDNN >60 ms and RMSSD >40 ms. After covariate adjustment, post-COVID patients were more likely to have SDNN >60 msn (OR: 2.4, 95% CI:1.2-12.8) and RMSSD >40 ms (OR: 2.5, 95% CI: 1.4-9.2). CONCLUSION: This study revealed parasympathetic overtone and increased HRV in patients with history of COVID-19. This may explain the unresolved orthostatic symptoms occurring in post-COVID period which may be associated with autonomic imbalance.

INTRODUCTION: In patients who have undergone interventional cardiac procedures, the risk of bleeding is higher than in patients who received conservative treatment due to multiple medications and comorbidities. AIM: This study aimed to evaluate the usefulness of the age, creatinine and ejection fraction (ACEF) score for predicting bleeding events and to compare short- and long-term clinical outcomes according to the ACEF score in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI) with bail-out tirofiban therapy (BOTT). MATERIAL AND METHODS: A total of 2,543 patients were included and divided into three groups according to the following ACEF score tertiles: T1 (ACEFlow ≤ 1.033), T2 (1.033 < ACEFmid ≤ 1.371), and T3 (ACEFhigh > 1.371). The main outcomes measured were the incidence rates of relevant bleeding events and mortality within 30 days and 3 years after the procedure. RESULTS: A total of 73 (2.9%) patients had Bleeding Academic Research Consortium bleeding events of grades 3, 4 or 5 and 104 (4%) patients died in a 30-day period. The ACEF score was effective at predicting 30-day bleeding (area under the receiver operating characteristic curve (AUC): 0.658, 95% confidence interval (CI): 0.579-0.737; p < 0.001), 30-day mortality (AUC = 0.701, 95% CI: 0.649-0.753; p < 0.001) and 3-year mortality (AUC = 0.778, 95% CI: 0.748-0.807; p < 0.001) events. Considering the ACEF score tertiles, T3 patients presented greater 30-day bleeding (1.6%, 2.8% and 4.1%; odds ratio (OR) = 2.56, 95% CI: 1.37-4.80), 30-day mortality (1.7%, 3.5% and 7.1%; OR = 4.53, 95% CI: 2.51-8.18) and 3-year mortality (6.4%, 11% and 19.8%; hazard ratio = 3.56, 95% CI: 2.58-4.91) risks. CONCLUSIONS: The ACEF score is a user-friendly tool with excellent predictive value for bleeding events and mortality in patients undergoing pPCI with BOTT.
RESUMEN
Mad honey intoxication (MHI) is a food-induced clinical condition that usually presents with cardiovascular symptoms and can lead to life-threatening arrhythmias if not diagnosed and treated early. No data exist in the literature on the presence of interatrial block (IAB) after food intoxication. In our study, we sought to investigate atrioventricular electrocardiography (ECG) parameters and determine the frequency of IAB in patients with MHI. In total, 76 patients diagnosed with MHI were included in our retrospective study. Twelve-lead ECGs were performed and participants were divided into two groups according to the presence of IAB in the reference ECG. The P maximum (Pmax), P minimum (Pmin), P dispersion (Pdisp), T peak to T end (Tp-Te) interval and QT dispersion (QTdisp) values were compared between the two groups. IAB was detected in 28 (35.5%) of 76 MHI patients included in the final analysis. Pmax duration (122 ± 8; p < 0.001) and PD (69 ± 11; p < 0.001) were significantly higher in the IAB ( +) group. During regression analysis, Pmax [odds ratio (OR) 1.158, 95% confidence interval (CI) 1.036-1.294; p = 0.010] and Pd (OR 1.086, 95% CI 1.001-1.017; p = 0.046) were independently associated with IAB. Pmax and Pd area under the receiver operating characteristic curve values for IAB prediction were 0.926 (95% CI 0.841-1,000; p < 0.001) and 0.872 (95% CI 0.765-0.974; p < 0.001), respectively. ECG changes are common in patients presenting with MHI. These patients need to be followed up clinically in terms of progression to arrhythmic events that may occur in the future.

BACKGROUND: An increase in short-term mortality can be found among older patients with hemodynamically stable acute pulmonary embolism (APE) who have signs of right ventricular (RV) dysfunction. AIMS: This study was designed to assess whether any difference exists among clinical, laboratory, electrocardiography and echocardiography parameters between older and younger patients diagnosed with APE. METHODS: The study sample included a total of 635 patients with confirmed APE who were divided into two groups of older (65 years and older) and younger (younger than 65 years) individuals. Comparisons were performed between these groups in terms of clinical, predisposing factors and laboratory, electrocardiographic and echocardiographic parameters. RESULTS: Analyses of 295 (46.4%) older and 340 (53.6%) younger patients diagnosed with APE were performed. Female sex, Pulmonary Embolism Severity Index score and baseline creatinine levels were higher in the older group. Also, the frequency of atrial fibrillation, RV outflow tract parasternal long-axis proximal diameter, RV end-diastolic diameter (RV-EDD) basal (apical four-chamber) and RV systolic pressure were significantly greater in older patients with APE. A total of 30 (4.7%) deaths were observed during the in-hospital period [21 (7.1%) older vs 9 (2.6%) younger patients; p < 0.01]. In the multivariate logistic regression analysis, age, white blood cell count (WBC), left ventricular ejection fraction (LVEF), RV-EDD basal and tricuspid annular plane systolic excursion (TAPSE) of less than 16 mm were found to be independently associated with in-hospital mortality. CONCLUSION: Older patients might experience greater rates of RV dilatation, RV dysfunction and atrial fibrillation during APE. In addition to age; elevated WBC, low LVEF, increased RV-EDD basal and TAPSE of less than 16 mm were independent predictors of mortality among study population.

This study evaluated the impact of the baseline estimated glomerular filtration rate (eGFR) on clinical and angiographic outcomes and long-term in-stent restenosis (ISR) rates in patients undergoing elective carotid artery stenting (CAS) procedures. Consecutive patients who underwent CAS were retrospectively enrolled (n = 456). At the end of 3 years of follow-up, patients who had died or were lost follow-up were excluded from the study and a final analysis was performed using data from the remaining 405 patients. The study population (n = 405) was divided into 3 tertiles based on the tertile values of the eGFR level (T1, T2, and T3); then, clinical and procedural characteristics and 3-year ISR rates were compared between the groups. An ISR of 50% was detected in 49 (12%) surviving patients. The 3-year ISR was higher among patients with the lowest eGFR values (T1) by 3.7 times (95% CI: 2.01-11.38) than that among patients with the highest eGFR values (T3). These significant relationships persisted following adjustment for confounders. A lower baseline eGFR level was significantly associated with an increased ISR rate. Decreased renal function may be a predictor of ISR after CAS using first-generation stents.

OBJECTIVES: Contrast-induced acute kidney injury (CI-AKI) is a life-threatening complication that leads to comorbidities and prolonged hospital stay lengths in the setting of peripheral interventions. The presence of some CI-AKI risk factors has already been investigated. In this study, we evaluated the predictors of CI-AKI after carotid artery stenting. METHODS: A total of 389 patients with 50% to 99% carotid artery stenosis who underwent carotid artery stenting were included in this study. Patients were grouped according to CI-AKI status. RESULTS: CI-AKI developed in 26 (6.6%) patients. Age, baseline creatinine level, neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were higher and estimated glomerular filtration rate, haemoglobin and lymphocyte count were lower in CI-AKI patients. In the multivariate regression analysis, the neutrophil-to-lymphocyte ratio triggered a 1.39- to 2.63-fold increase in the risk of CI-AKI onset (p < 0.001). CONCLUSIONS: The neutrophil-to-lymphocyte ratio may be a significant predictor of CI-AKI in patients with carotid artery stenting and higher neutrophil-to-lymphocyte ratio values may be independently associated with CI-AKI.

BACKGROUND: Despite the important role of some haematological parameters in tendency to thrombosis is known, their relationship with long-term stent thrombosis (ST) remains unclear. AIMS: This study aimed to investigate the association between the mean platelet volume (MPV) to platelet count (PC) ratio and long-term ST and mortality in patients with ST-segment-elevation myocardial infarction (STEMI) treated successfully by primary percutaneous coronary intervention (pPCI). METHODS: In a retrospective cohort study, according to their baseline MPV/PC ratios, 3667 consecutive STEMI patients undergoing pPCI were divided into three groups: tertile 1 (T1) (n = 1222, 0.357 ≥ MPV/PC ≥ 0.043), tertile 2 (T2) (n = 1222, 0.033 < MPV/PC < 0.043) and tertile 3 (T3) (n = 1223, 0.009 ≤ MPV/PC ≤ 0.032). Patients were followed up with for 5 years, focusing on ST and all-cause mortality outcomes. RESULTS: Patients with T1 displayed a greater 5-year ST rate, including a 2.76-fold greater (95% confidence interval 1.68-10.33) rate than that of patients with T3, who had the lowest rates and were used as the reference group. Meanwhile, the 5-year mortality rate was similarly higher among patients with T1 by 1.72 times (95% confidence interval 1.33-2.22) relative to that among patients with T3. These significant relationships persisted even after adjustment for all confounders. CONCLUSION: We found that higher MPV/PC ratios were associated with long-term ST and mortality. The MPV/PC ratio may constitute both a rapid and an easily obtainable parameter for identifying reliably high-risk patients who have undergone pPCI.

BACKGROUND: Although aortic valve replacement (AVR) when successfully performed boasts low mortality rates in selected patients, prosthesis-patient mismatch (PPM) can be found in the majority of these individuals. Limited research is available supporting the benefit of two-dimensional speckle tracking echocardiography (2D-STE) in patients with severe PPM. This study sought to assess myocardial strain using 2D-STE to determine the relationship between subclinical left ventricular (LV) dysfunction and aortic PPM in patients undergoing AVR with preserved LV ejection fraction. MATERIAL AND METHODS: We retrospectively examined all consecutive patients with isolated AVR who presented to our center from 2005 to 2018. The data of 1086 patients were analyzed. Severe PPM was defined as an indexed effective orifice area of 0.65â¯cm2/m2 or less. As a result of the detailed assessment, 54 patients meeting the eligibility criteria were included in the study. Baseline data were collected and compared between the two groups of patients with severe PPM (nâ¯= 27) and those with normofunctional aortic prosthesis valve as a control group (nâ¯= 27). All patients underwent baseline echocardiography. Global longitudinal strain (GLS) and global circumferential strain (GCS) were evaluated by 2D-STE. RESULTS: When compared with controls, patients with severe PPM had significantly decreased GLS (18.6⯱ 2.9 vs. 21.4⯱ 2.1; pâ¯<â¯0.01) and GCS (17.2⯱ 3.6 vs. 21.7⯱ 2.1; pâ¯<â¯0.01) values. CONCLUSION: In addition to standard clinical and echocardiographic parameters, GLS and GCS suggest subclinical dysfunction and have incremental value in patients with severe PPM.

OBJECTIVE: The aim of this study was to assess the clinical characteristics of patients with heart failure and preserved ejection fraction (HFpEF) and atrial fibrillation (AF) and compare them with those of HFpEF patients without AF. METHODS: This study was a sub-group analysis of a multicenter, observational, and cross-sectional registry conducted in Turkey (ClinicalTrials.gov identifier: NCT03026114). Patients with HFpEF were divided into 2 groups: HFpEF with AF and HFpEF with sinus rhythm (SR), and the clinical characteristics of the groups were compared. RESULTS: In a total of 819 HFpEF patients (median age: 67 years; 58% women), 313 (38.2%) had AF. Compared to the patients with SR, those with AF were older (70 years vs 66 years; p<0.001) and more symptomatic, with a higher rate of classification as New York Heart Association functional class III-IV, paroxysmal nocturnal dyspnea, orthopnea, palpitations, fatigue, pulmonary crepitations, and peripheral edema. The hospitalization rate for heart failure was higher (28.4% vs 12.6%; p<0.001) in patients with AF, and participants with AF had higher level of N-terminal pro-B-type natriuretic peptide (887 pg/mL vs 394.8 pg/mL; p<0.001) and higher left atrial volume index level. Patients without AF had a higher burden of diabetes mellitus, obstructive sleep apnea, and coronary artery disease. The prescription rate of nondihydropyridine calcium blockers, digoxin, loop diuretics, and anticoagulant drugs was higher in the AF group. CONCLUSION: The results of this study revealed that in a large Turkish cohort with HFpEF, significant clinical differences were present between those with and without AF and. Further prospective studies are needed to clarify the prognostic implications of AF in this growing heart failure population in our country.

Background: In addition to proinflammatory properties, eosinophils can stimulate platelet activation and enhance prothrombotic pathways. In this study, we aimed to investigate the association between the eosinophil percentage (EOS%) and major adverse cardiac events (MACE) in patients with ST-segment elevation myocardial infarction (STEMI). Methods: This study enrolled a total of 1,909 patients who were diagnosed with STEMI. Ventricular arrhythmia, reinfarction, the need for cardiopulmonary resuscitation, target vessel revascularization, congestive heart failure, and cardiovascular mortality during index hospitalization were defined as MACE. Results: Three hundred and eighty patients (19.7%) reached the combined endpoint with MACE. The rates of inhospital mortality and MACE were significantly higher in low EOS% group as compared to high EOS% group (4% vs. 1.1%, p < 0.01 and 32.8% vs. 11.3%, p < 0.01, respectively). On multivariate logistic regression analyses, EOS% (OR = 0.44, p < 0.01) was found to be one of the independent predictors of MACE. The EOS% lower than 0.60 on admission predicted inhospital MACE with a sensitivity of 68% and a specificity of 72% (AUC: 0.684, p < 0.01). Conclusions: Low EOS% on admission may be associated with high inhospital MACE in STEMI patients. EOS% may be used as a novel biomarker for risk stratification of these patients.
RESUMEN
INTRODUCTION: This study aims to evaluate the effect of primary percutaneous coronary intervention (PCI) and thrombolytic therapy (TT) on the in-hospital adverse events, in-hospital and long-term mortality in patients over 65 years of age with acute ST-segment elevation myocardial infarction (STEMI). MATERIAL AND METHODS: A total of 111 retrospectively screened patients (73 males, mean age: 73.4 ±5.9 years) over 65 years of age with STEMI, who underwent TT or primary PCI, were included in the study. Patients' characteristics, in-hospital outcomes, and 6-month and 1-year mortalities were recorded. RESULTS: Our study was conducted with 111 patients over 65 years of age with STEMI (73 males, 38 females). Of the patients, 66 (59.5%) were treated with thrombolytics, and 45 (40.5%) patients underwent primary PCI. Door-to-needle time was 25.9 ±7.8 min in the TT group, whereas door-to-balloon time was 84.4 ±20.0 min in the PCI group. Time from symptom onset to hospital admission was 213.6 ±158.4 min in the thrombolytic group, and 166.8 ±112.8 min in the PCI group. Rescue PCI was performed in 7 (10.6%) patients in the TT group due to lack of reperfusion. Recurrent infarction was observed in 5 (7.6%) patients in the TT group and in 2 (4.4%) patients in the PCI group. Non-haemorrhagic stroke was observed in 1 (1.5%) patient in the thrombolytic-administered group and in 4 (8.9%) patients in the PCI group. No intracranial haemorrhage was observed in any patient. Major haemorrhage was observed in 4 (6.1%) patients in the TT group and in 4 (8.9%) patients in the PCI group. Six-month and 1-year mortalities were present in 15 (22.7%) patients and 19 patients in thrombolytic group, and 8 (17.8%) and 8 (17.8%) patients in the PCI group, respectively. Binary logistic regression analysis indicated that the patient's age was the only predictor for 1-year mortality (odds ratio (OR) = 1.1, 95% confidence interval (CI): 1.019-1.188, p = 0.015). CONCLUSIONS: Considering the in-hospital adverse outcomes, in-hospital mortality, and 6-month mortality rates, TT and primary PCI have similar effects in STEMI patients aged 65 years and over according to the results of our study. Although 1-year mortality was higher in the TT group, it was not statistically significant.
RESUMEN
OBJECTIVE: This study aimed to examine gender-based differences in epidemiology, clinical characteristics, and management of consecutive patients with heart failure with mid-range ejection fraction (HFmrEF) and heart failure with preserved ejection fraction (HFpEF). METHODS: The APOLLON trial (A comPrehensive, ObservationaL registry of heart faiLure with mid-range and preserved ejection fractiON) is a multicenter, cross-sectional, and observational study. Consecutive patients with HFmrEF or HFpEF who were admitted to the cardiology clinics were included (NCT03026114). Herein, we performed a post-hoc analysis of data from the APOLLON trial. RESULTS: The study population included 1065 (mean age of 67.1+-10.6 years, 54% women) patients from 11 sites in Turkey. Compared with men, women were older (68 years vs. 67 years, p<0.001), had higher body mass index (29 kg/m2 vs. 27 kg/m2, p<0.001), and had higher heart rate (80 bpm vs. 77.5 bpm, p<0.001). Women were more likely to have HFpEF (82% vs. 70.9%, p<0.001), and they differ from men having a higher prevalence of hypertension (78.7% vs. 73.2%, p=0.035) and atrial fibrillation (40.7% vs. 29.9%, p<0.001) but lower prevalence of coronary artery disease (29.5% vs. 54.9%, p<0.001). Women had higher N-terminal pro-B-type natriuretic peptide (691 pg/mL vs. 541 pg/mL, p=0.004), lower hemoglobin (12.7 g/dL vs. 13.8 g/dL, p<0.001), and serum ferritin (51 ng/mL vs. 64 ng/mL, p=0.001) levels, and they had worse diastolic function (E/e'=10 vs. 9, p<0.001). The main cause of heart failure (HF) in women was atrial fibrillation, while it was ischemic heart disease in men. CONCLUSION: Clinical characteristics, laboratory findings, and etiological factors are significantly different in female and male patients with HFmrEF and HFpEF. This study offers a broad perspective for increased awareness about this patient profile in Turkey.
