Higher C-Reactive Protein to Albumin Ratio Portends Long-Term Mortality in Patients with Chronic Heart Failure and Reduced Ejection Fraction.

Background and Objectives: In this study, we aimed to investigate the prognostic value of the C-reactive protein to albumin ratio (CAR) for all-cause mortality in patients with chronic heart failure with reduced ejection fraction (HFrEF). Materials and Methods: In total, 404 chronic HFrEF patients were included in this observational and retrospective study. The CAR value of each patient included in this analysis was calculated. We stratified the study population into tertiles (T1, T2, and T3) according to CAR values. The primary outcome of the analysis was to determine all-cause mortality. Results: The median follow-up period in our study was 30 months. In the follow-up, 162 (40%) patients died. The median value of CAR was higher in patients who did not survive during the follow-up [6.7 (IQR = 1.6-20.4) vs. 0.6 (IQR = 0.1-2.6), p < 0.001]. In addition, patients in the T3 tertile (patients with the highest CAR) had a higher rate of all-cause mortality [n = 90 cases (66.2%), p < 0.001]. Multivariate Cox regression analysis revealed that CAR was an independent predictor of mortality in patients with HFrEF (hazard ratio: 1.852, 95% confidence interval: 1.124-2.581, p = 0.005). In a receiver operating characteristic curve analysis, the optimal cut-off value of CAR was >2.78, with a sensitivity of 66.7% and specificity of 76%. Furthermore, older age, elevated N-terminal pro-brain natriuretic peptide levels, and absence of a cardiac device were also independently associated with all-cause death in HFrEF patients after 2.5 years of follow-up. Conclusions: The present study revealed that CAR independently predicts long-term mortality in chronic HFrEF patients. CAR may be used to predict mortality among these patients as a simple and easily obtainable inflammatory marker.

Association of ectatic non-infarct-related artery with 1-month stent thrombosis in patients with ST elevation myocardial infarction.

BACKGROUND: Ectatic infarct-related artery (IRA) has been shown to be associated with higher thrombus burden, no-reflow, stent thrombosis (ST) and major adverse cardiovascular events in patients with ST-elevation myocardial infarction (STEMI). The effect of ectatic non-IRA on ST without ectatic IRA is not known. We aimed to assess the effect of ectatic non-IRA presence on ST within 1 month after primary percutaneous intervention (pPCI) in patients with STEMI. METHODS: A total of 1541 patients with a diagnosis of STEMI and underwent pPCI between 2015 and 2020 were retrospectively included in the study. Patients with and without 1 month ST were compared. Penalised logistic regression method was used to assess the association between ST and candidate predictors due to the risk of overfitting. RESULTS: Median age of the study group was 56.5 (48.7 to 67.2) years. The Synergy between PCI with Taxus and Cardiac Surgery (SYNTAX) score, ectatic non-IRA presence and use of tirofiban were significantly higher in the ST group (18.2±9.9 vs 15.1±9.9, p=0.03; 25% vs 7.2%, p<0.001; 54.2% vs 30.5%, p<0.001; respectively). Significantly higher thrombus aspiration (14.3% vs 6.7%, p=0.03) and lower stent implantation (67.7% vs 84%, p<0.001) rates were observed in ectatic IRA group compared with ectatic non-IRA group. In multivariable analysis, ectatic non-IRA presence was independently associated with 1-month ST (OR 4.01, 95% CI 1.86 to 8.63, p=0.01). CONCLUSION: Ectatic non-IRA presence without ectatic IRA in patients with STEMI increases the risk of ST within the first month of pPCI.

Effects of RAAS blocker use on AKI in elderly hypertensive STEMI patients with propensity score weighed method.

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.

Evaluation of Low-density Lipoprotein Cholesterol Target Attainment Rates According to the 2016 and 2019 European Society of Cardiology/European Atherosclerosis Society Dyslipidemia Guidelines for Secondary Prevention in Patients with Acute Myocardial Infarction.

BACKGROUND: High-intensity statin (HIS) therapy is widely recommended for secondary prevention after an acute myocardial infarction (AMI). The 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) dyslipidemia guidelines have lowered the target low-density lipoprotein cholesterol (LDL-C) level, which necessitates a more frequent use of nonstatin therapies. OBJECTIVES: The objectives of the study were to investigate the rate of LDL-C target attainment for secondary prevention in AMI patients. METHODS: This retrospective investigation included 1360 patients diagnosed with AMI in a tertiary heart center. Lipid parameters were collected within 24 h of admission and within 1 year after discharge. The medications used were retrieved from medical records, and the lowest LDL-C levels after statin treatment were used to assess the effectiveness of the therapy. LDL-C target attainment was defined according to the 2016 ESC/EAS dyslipidemia guidelines as an LDL-C level of < 70 mg/dL and a ≥ 50% reduction from baseline. In addition, the rate of LDL-C target attainment according to the 2019 fromESC/EAS guidelines was defined as an LDL-C level of < 55 mg/dL and a ≥ 50% reduction baseline. RESULTS: In total, 502 (36.9%) and 247 (18.2%) patients reached the LDL-C targets according to the 2016 and 2019 ESC/EAS guidelines, respectively. The admission LDL-C levels were significantly lower and HIS treatment was used more frequently in patients who subsequently attained the LDL-C goal. Remarkably, 461 (34%) patients failed to reach the LDL-C goals despite HIS treatment. Only 27 (1.9%) patients were prescribed ezetimibe. CONCLUSION: The rate of LDL-C goal attainment in AMI patients was low, which indicates the need for combination statin and non-statin lipid-lowering therapies.

Change in Frequency and Predictors of Erectile Dysfunction With Changes in the International Index of Erectile Function-Erectile Function Domain Score in Patients With ST-Elevation Myocardial Infarction: A Prospective, Longitudinal Study.

BACKGROUND: Erectile dysfunction (ED) has been proposed as an early indicator for future coronary and peripheral vascular disease. AIM: We aimed to investigate the longitudinal change in proportion and predictors for ED with changes in erectile function domain (EFD) of the International Index of Erectile Function-15 (IIEF-15) in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PPCI). METHODS: Between December 2018 and June 2019, 286 male patients aged between 40 and 70 years who were treated with PPCI for STEMI were included. The patients were asked to complete the IIEF-EFD form 3 days after the procedure for the evaluation of baseline erectile functions. During follow-up 3 months after the index procedure, the patients were asked to refill the IIEF-EFD form. Both baseline and third-month IIEF-EFD scores were calculated, and the patients were classified into ED severity groups as per the IIEF-EFD scores. A linear mixed model was used to identify predictors of ED at 3 months. OUTCOMES: This study identifies the prevalence and predictors of ED with STEMI who underwent PPCI. RESULTS: The median age was 54 (range 48-61) years. The median IIEF-EFD scores at 3 days and 3 months were 25.5 (range 20.0-27.0) and 22.00 (range 18.25-25.00), respectively. Half of the patients were found to have ED with varying severity as per baseline IIEF-EFD scores. This rate increased to 79% at the 3-month follow-up visit. The IIEF-EFD scores of the patients decreased over time (P < .001). Advanced age (ß = -0.603, se = 0.192, P = .002), presence of three-vessel coronary artery disease (ß = -3.828, se = 0.783, P < .001), and diabetes (ß = -2.934, se = 0.685, P < .001) were found to be inversely associated with the IIEF-EFD scores. CLINICAL IMPLICATIONS: Advanced age, presence of three-vessel disease, and diabetes mellitus are the indicators of sexual rehabilitation needs in patients after STEMI. STRENGTHS & LIMITATIONS: This is the first study investigating the predictor variables for the development of ED after coronary artery disease treatment. The limitations include the lack of evaluation of anxiety and depression and the measurements of testosterone levels. CONCLUSION: The prevalence of ED was high among patients with coronary artery disease, and the frequency of ED increased during 3-month follow-up. Advanced age, three-vessel disease, and diabetes were significant predictors of ED with changes in IIEF-EFD score in patients with STEMI who underwent PPCI. Karabay E, Karsiyakali N, Cinier G, et al.

Long-term clinical outcomes and prognoses of ST-segment elevation myocardial infarction patients who present with tombstoning ST-segment elevation.

INTRODUCTION: Although patients with tombstoning ST-segment elevation (Tomb-ST) usually have poor in-hospital and short-term survival rates, no studies have examined the long-term clinical outcomes and prognosis of ST-segment elevation myocardial infarction (STEMI) patients who have this electrocardiographic pattern. Therefore, we aimed to evaluate the long-term clinical events and mortality of such patients in this study. METHODS: In this retrospective analysis, we included 335 consecutive patients who were diagnosed with acute anterior wall-STEMI from January 2015 to June 2018. The criteria for the definition of Tomb-ST were accepted as provided in a previous study. Endpoints of the study were the incidence of significant in-hospital and long-term major adverse clinical events (MACE) including the composite of total death, myocardial reinfarction, and hospitalizations due to heart failure. RESULTS: Patients who presented with Tomb-ST had significantly higher in-hospital and long-term mortality (10% [n = 12 patients] vs. 2.3% [n = 5 patients]; p < 0.001and 6.5% [n = 7 patients] vs. 1.9% [n = 4 patients]; p = .04, respectively). In a multivariate traditional and penalized Cox proportional hazard regression analysis, this type of electrocardiographic pattern was found as independent predictor of long-term MACE (Odds ratio [OR]: 3.82, 95% confidence interval [CI]: 1.91-7.63, p < .001 and OR: 4.36, 95% CI: 1.97-9.66, p < .001, respectively). CONCLUSION: In the present study, we observed that the presence of Tomb-ST might be an independent predictor of long-term MACE in STEMI patients. To the best of our knowledge, this is the first study to evaluate the long-term MACE of such patients.

A new electrocardiographic pattern indicating inferior myocardial infarction.

BACKGROUND: We identified a specific pattern that does not display contiguous ST-segment elevation (STE), indicating acute inferior myocardial infarction (MI) with concomitant critical stenoses on the other coronary arteries. We sought to define the frequency, underlying anatomic substrate, diagnostic power and prognostic implications of this pattern. METHODS: One thousand patients with a diagnosis of non-STEMI were enrolled as the study group. Within the same date range, all patients with inferior STEMI and 1000 patients, who had been excluded for MI (no-MI), were also enrolled. The coronary angiograms were reviewed by two interventional cardiologists, who were blinded to the ECGs. Echocardiographic wall motion bullseye displays and coronary angiography maps were constructed for each group. The dead or alive status was checked from the electronic national database. RESULTS: The final study population consisted 2362 patients. The prespecified ECG pattern was observed in 6.3% (61/966) of the non-STEMI cohort and 0.5% (5/1000) of no-MI patients. These patients had a larger infarct size as evidenced by 24-hour troponin levels, higher frequency of angiographic culprit lesion, and higher frequency of composite acute coronary occlusion endpoint compared to their non-STEMI counterparts. On the other hand, they had a similar in-hospital (5% vs. 4%, respectively; P = 0.675) and one-year mortality compared to the patients with inferior STEMI (11% vs. 8%, respectively; P = 0.311). CONCLUSION: We here define a new ECG pattern indicating inferior MI in patients with concomitant critical lesion(s) in coronary arteries other than the infarct-related artery. Patients with this pattern have multivessel disease and higher mortality.

The established electrocardiographic classification of anterior wall myocardial infarction misguides clinicians in terms of infarct location, extent and prognosis.

BACKGROUND: The currently used scheme for the classification of infarct location and extent in anterior myocardial infarction (MI) is intuitive rather than being evidence-based, and recent evidence suggests that it may be misleading both in anatomic and prognostic sense. MATERIAL AND METHODS: Consecutive patients with the diagnosis of anterior MI were enrolled. All electrocardiograms (ECG) were first classified according to established scheme and then reassessed using newer criteria for angiographic site of occlusion. The site of left anterior descending (LAD) occlusion was determined using multiple angiographic views. Clinic, echocardiographic and angiographic outcomes were compared. RESULTS: A total of 379 anterior MI cases were enrolled, final study population consisted of 267 patients. The established scheme did not predict infarct size or adverse outcomes. Location of the myocardium subtended by the occluded coronary network did not match with the anatomic location as ECG classification implies. Many high-risk patients with proximal LAD were classified as "anteroseptal", whereas the majority of the patients labeled as "extensive anterior MI" had in fact distal occlusions. On the other hand, expert interpretation was fairly accurate in predicting adverse outcomes and the site of angiographic involvement. CONCLUSION: Classifying patients according to the established scheme neither gives prognostic information nor accurately localizes infarction. It should be regarded as obsolete and its use should be abandoned. Instead, the extent of infarction can be inferred from newer criteria provided by the angiographic correlation studies.

A tale of two formulas: Differentiation of subtle anterior MI from benign ST segment elevation.

BACKGROUND: It may sometimes be difficult to differentiate subtle ST-segment elevation (STE) due to anterior myocardial infarction (MI) from benign variant (BV) STE. Recently, two related formulas were proposed for this purpose. However, they have never been tested in an external population. MATERIALS AND METHODS: Consecutive patients from May 2017 to January 2018, who were admitted with the diagnosis of acute anterior STEMI, were enrolled. Electrocardiograms were systematically reviewed and only subtle ones were included. First 200 consecutive patients with noncardiac chest pain were also enrolled as a control group. Relevant electrocardiographic parameters were measured. RESULTS: A total of 379 anterior MI and 200 BV-STE cases were enrolled during study period. A total of 241 patients in STEMI group were excluded for not matching subtleness criteria, four patients in control group were also excluded because of prior left-anterior descending artery intervention. The three-variable formula, with recommended cut-point of 23.5, had a sensitivity, specificity, and diagnostic accuracy of 73.9%, 86.7%, and 81.4%, respectively. The four-variable formula, with the published cut-point of 18.2, had a sensitivity, specificity, and diagnostic accuracy of 83.3%, 87.7%, and 85.9%, respectively. CONCLUSION: Three- and four-variable formulas with recommended cutoffs have a reasonable sensitivity, specificity, and diagnostic accuracy in differentiating subtle STEMI with BV-STE. Although both perform well, the four-variable formula has a higher sensitivity, specificity, and diagnostic accuracy and should be preferred.

An algorithm for the differentiation of the infarct territory in difficult to discern electrocardiograms.

BACKGROUND: In a minority of the patients presenting with ST-segment elevation (STE) myocardial infarction (MI), electrocardiogram (ECG) may show a balanced STE in both anterior and inferior lead groups and may cause diagnostic confusion about involved myocardial territory. In this study, we sought ECG clues which may facilitate discriminating (1) MI location and then (2) culprit artery in patients with difficult-to-discern ECGs. MATERIAL AND METHODS: Consecutive patients with the diagnosis of STEMI were scanned and patients with ECGs displaying both anterior and inferior STE were enrolled. ECGs with obvious ST elevation in either lead group and reciprocal ST-segment depression were excluded. Predictive power of several ECG variables has been analyzed and an algorithm has been constructed. RESULTS: A total of 959 STEMI cases were scanned, the final study population was consisted of 114 patients. Our algorithm for locating MI territory had a sensitivity, specificity, positive and negative predictive value of 72.1%, 92.5%, 91.7% and 74.2% for inferior versus anterior location, respectively (P < 0.001, φ = 0.652). As anterior MI was strictly reserved for left anterior descending (LAD) artery occlusion, these diagnostic values were also valid for discriminating circumflex artery [Cx]/right coronary artery [RCA] versus LAD as the culprit artery. In patients classified as having inferior MI, an STE in lead III greater than STE in lead II favored RCA over Cx as the culprit artery with a sensitivity, specificity, positive and negative predictive value of 97%, 46.6%, 80% and 87.5%, respectively (P < 0.001; φ = 0.544). CONCLUSION: Our algorithm can be used in difficult-to-discern ECGs for defining involved myocardial territory and culprit artery.

[Turkish Adult Risk Factor survey 2014: Overall mortality and coronary disease incidence in Turkey's geographic regions]. / TEKHARF 2014 taramasi ve Türkiye'de cografi bölgelere göre ölüm orani ile koroner hastalik insidansi.

OBJECTIVE: This study aimed to examine the overall and coronary mortality in the 2014 Turkish Adult Risk Factor Study survey, and the distribution of cumulative mortality and incident coronary heart disease (CHD) across 7 geographic regions. METHODS: Information on mode of death was appropriately obtained. Information collected from survivors was based on history, examination of the cardiovascular system and the Minnesota coding of electrocardiograms. Cox regression analyses were performed. RESULTS: Of the 1.323 participants to be surveyed, 87 were lost to follow-up, 753 examined, and 35 ascertained as deceased. In 448 subjects, verbal information alone was obtained regarding health status. Nineteen deaths were of coronary and cerebrovascular origin. Cumulative 24-year assessment of the entire cohort in the age bracket 45-74 years disclosed high coronary mortality, at 7.3 per 1000 person-years in men and 3.8 in women, and recorded a limited decline of 18% since the year 2000. Age-adjusted Cox regression analysis, comprising 614 deaths and 482 incident CHD over a follow-up of 9.6 years, revealed higher mortality rates in the Mediterranean region and in men in the Black Sea and Marmara regions. The age-adjusted CHD incidence was significantly higher in males of the Mediterranean and females of the Southeast regions. An estimated 400-420.000 incident CHD cases develop currently each year in Turkey. CONCLUSION: The generally high age-adjusted overall mortality in Turkey displays significant differences across geographic regions. Age-adjusted CHD incidence is not regressing sufficiently, and is especially high among men of the Mediterranean and women of the Southeast regions.

Silver Nanoparticle-Assisted Electrochemically Exfoliated Graphene Inks Coated on PVA-Based Self-Healing Polymer Composites for Soft Electronics.

Smart sensors with self-healing capabilities have recently aroused increasing interest in applications in soft electronics. However, challenges remain in balancing the sensors' self-healing and compatibility between their sensing and substrate layers. This study evaluated several self-healing polymer substrates and graphene ink-based strain-sensing coatings. The optimum electrochemically exfoliated graphene (e-graphene)/silver nanoparticle-coated tannic acid (TA)/superabsorbent polymer/graphene oxide (GO) blended poly(vinyl alcohol) polymer composites exhibited improvements of 47.1 and 39.2%, respectively, for the healing efficiency in a substrate crack area and in the graphene-based sensing layer due to conductive layer adhesion. While TA was found to improve healing efficiency on the coating surface by forming hydrogen bonds between the sensing and polymer layers, GO healed the polymer surface due to its ability to form bonds in the polymer matrix. The superabsorbent polymer was found to absorb excess water in e-graphene dispersion due to its host-guest interaction, while also reducing the coating thickness.

Assessment of Lipoprotein (a) Levels in Patients with Atherosclerotic Cardiovascular Disease: Single Center Experience from Türkiye.

OBJECTIVE: This study aims to evaluate the role of elevated lipoprotein (a) [Lp(a)] levels as a potential contributor to residual risk in individuals with atherosclerotic cardiovascular disease (ASCVD). Considering that approximately 90% of Lp(a) levels are genetically determined and can vary regionally, we assessed Lp(a) levels in a cohort of ASCVD patients from the Turkish population, where data is currently limited. METHODS: We conducted a retrospective analysis of data and Lp(a) measurements collected from individuals diagnosed with ASCVD at a single center. RESULTS: The analysis included Lp(a) levels of 1193 consecutive individuals. The mean Lp(a) level was 28.2 mg/dL, with a median of 16 mg/dL and an interquartile range (IQR) from the 25th to the 75th percentile, 7 mg/dL to 39 mg/dL. The highest recorded Lp(a) level was 326 mg/dL. Among the cases, 18.7% exhibited Lp(a) levels ≥ 50 mg/dL, 10.8% had levels ≥ 70 mg/dL, and 5.8% had levels ≥ 90 mg/dL. The mean levels of low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) were 132 ± 47 mg/dL and 212 ± 54 mg/dL, respectively. Lp(a) levels were significantly higher in females compared to males. Furthermore, the proportion of females with Lp(a) levels ≥ 90 mg/dL was higher than in males (11.4% vs. 1.4%; P < 0.01). Additionally, a modest but significant correlation was observed between Lp(a) levels and TC (r = 0.075, P = 0.01) as well as LDL-C (r = 0.106, P < 0.01). CONCLUSION: This study revealed that Lp(a) concentrations were higher in women and statin users among ASCVD patients and identified a weak but significant correlation between Lp(a) levels and both TC and LDL-C.

Relationship Between CHA2DS2-VASc Score on Admission and In-Hospital Major Adverse Cardiovascular Events in Patients Diagnosed With ST-Elevation Myocardial Infarction.

The CHA2DS2-VASc (congestive heart failure, hypertension, age, diabetes mellitus, stroke, vascular disease, sex) scoring system, which includes conventional risk factors of coronary artery disease, was originally created to quantify the risk of thromboembolism in patients with atrial fibrillation. This study evaluated the usefulness of this score to predict adverse outcomes in STEMI (ST-elevation myocardial infarction) patients without atrial fibrillation. Primary end points were identified as MACE (major adverse cardiovascular events) which included in-hospital death or cerebrovascular accident. MACE rate was 10% (193 patients). The CHA2DS2-VASc score was an independent predictor of MACE (95% CI, 2.31 [1.37-3.9]; P = .0016). Other independent predictors of MACE included heart rate (95% CI, 1.56 [0.97-2.50]; P = .0242), admission Killip class (95% CI, 24.19 [10.74-54.46]; P < .0001), admission creatinine level (95% CI, 1.54 [1.10-2.16]; P = .0024), peak CK-MB level (95% CI, 1.63 [0.98-2.70]; P = .0001), and no-reflow (95% CI, 2.45 [1.25-4.80]; P = .0085). A nomogram was developed to estimate the risk of in-hospital adverse outcomes for STEMI patients. The CHA2DS2-VASc score was an independent predictor of MACE in STEMI patients. Linear analysis of CHA2DS2-VASc score without dichotomization was the main difference of this study from others.

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

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

Ocular surface disorders in intensive care unit patients.

Patients in intensive care units (ICU) are at increased risk of corneal abrasions and infectious keratitis due to poor eyelid closure, decreased blink reflex, and increased exposure to pathogenic microorganisms. The aim of this retrospective study was to evaluate the ocular surface problems in patients who stayed in ICU more than 7 days and were consulted by an ophthalmologist. There were 26 men and 14 women with a mean age of 40.1 ± 18.15 years (range 17-74 years). Conjunctiva hyperemia, mucopurulent or purulent secretion, corneal staining, and corneal filaments were observed in 56.25%, 36.25%, 15%, and 5% of the eyes, respectively. Keratitis was observed in 4 patients (10%) who were treated successfully with topical antibiotics. Mean Schirmers test results were 7.6 ± 5.7 mm/5 min (median 6.5 mm/5 min) in the right, and 7.9 ± 6.3 mm/5 min (median 7 mm/5 min) in the left eyes. Schirmers test results were <5 mm/5 min in 40% of the subjects. The parameters did not show statistically significant difference according to mechanical ventilation, sedation, and use of inotropes. As ICU patients are more susceptible to develop dry eye, keratopathy, and ocular infections, they should be consulted by an ophthalmologist for early diagnosis of ocular surface disorders.

The Effect of Anesthesia Type Applied in Transcatheter Aortic Valve Implantation.

OBJECTIVE: Different results have been obtained in studies on the effect of anesthesia type applied during transcatheter aortic valve implantation on in-hospital outcomes. In this study, we aimed to investigate the association of the type of anesthesia with the lenght of stay in the intensive care unit and the need for inotropes in patients undergoing transcatheter aortic valve implantation. METHODS: A total of 140 patients who underwent transcatheter aortic valve implantation between January 2016 and January 2022 were retrospectively analyzed. The patients were divided into 2 groups as deep sedation and general anesthesia according to the type of anesthesia. RESULTS: The mean age of all patients was 78.5 ± 8.6 years, and 69 of the patients (49.3%) were female. Length of stay in intensive care unit, midazolam dosage, use of inotropic agents, and procedural hypotension were significantly lower in the deep sedation group than in the general anesthesia group [(1[1-2] vs. 1[1-2.5] days, P = 0.03), (2.1 ± 0.4 mg/kg vs. 2.3 ± 05, P = 0.02), (39 (37.9%) vs. 22 (59.5%), P = 0.02), (41 (39.8%) vs. 25 (67.6%), P = 0.004)]. General anesthesia was associated with increased use of inotropic agents during transcatheter aortic valve implantation compared to deep sedation (odds ratio = 2.93 95% CI = 1.18-7.30, P = 0.02). CONCLUSION: The use of inotropes is less in transcatheter aortic valve implantation procedures performed under deep sedation and length of stay in intensive care unit is shorter.

Body fat percentage and infarct size in patients with non-ST segment elevation myocardial infarction.

OBJECTIVE: Obesity is a global health problem that increases the risk of coronary artery disease (CAD). However in studies, it has been observed that when the disease develops, obese patients have a more favorable prognosis than leaner patients. This is called the "obesity paradox." This study aims to evaluate the effect of obesity assessed with body fat percentage (BFP) and relative fat mass (RFM) besides body mass index (BMI) on infarct size (IS) estimated from peak creatine kinase-MB (CK-MB) levels in patients with non-ST-segment elevation myocardial infarction (NSTEMI). METHODS: Patients with a diagnosis of NSTEMI who underwent coronary angiography between January 2017 and January 2022 were retrospectively evaluated. Patients without available anthropometric data to calculate BMI, BFP, and RFM and serial CK-MB measurements were excluded from the study. BMI was calculated using weight(kg)/(height[m])2 formula. Patients were dichotomized as obese (BMI≥30 kg/m2) and non-obese (BMI<30 kg/m2) to compare baseline characteristics. BFP and RFM were calculated from anthropometric data. Linear regression analysis was performed to define predictors of IS. RESULTS: Final study population consisted of 748 NSTEMI patients (mean age was 59.3±11.2 years, 76.3% were men, 36.1% of the patients were obese). Obese patients were more likely to be female, hypertensive, and diabetic. Smoking was less frequently observed in obese patients. Peak CK-MB levels were similar among groups. Obese patients had higher in-hospital left ventricular ejection fraction, and less severe CAD was observed in coronary angiographies of these patients. Multivariable regression analysis identified diabetes mellitus, systolic blood pressure, white blood cell count, hemoglobin, and BFP (ß=-4.8, 95% CI=-8.7; -0.3, p=0.03) as independent predictors of IS. CONCLUSION: Higher BFP is associated with smaller IS in NSTEMI patients. These findings support the obesity paradox in this patient group, but further, randomized controlled studies are required.

Successful Usage of FlexCath Steerable Catheter in Case of Atrial Septal Closure Device Comes Perpendicular to Interatrial Septum.

OBJECTIVE: Percutaneous closure of atrial septal defects is challenging in cases where the device is perpendicular to the septum during the procedure. Hence, different techniques, maneuvers, and auxiliary equipment may be required. We aimed to demonstrate the effectiveness of the FlexCath steerable catheter application in percutaneous closure of atrial septal defect cases in which the device was perpendicular to the septum. METHODS: Patients with atrial septal defect who presented to our clinic between January 2017 and December 2020 and were deemed eligible for percutaneous closure were included in the study. RESULTS: Atrial septal defects of 101 patients out of 110 patients were successfully closed using standard methods. Nine patients in whom it was seen if the device was perpendicular to the interatrial septum were successfully closed with FlexCath steerable catheter support. There was no statistically significant difference between patients in terms of age, gender, floopy rim, and multiple defects. In the group that was treated with FlexCath steerable catheter support, the aortic rim was smaller, and the defect diameter and the size of the atrial septal defects device were larger. The success of the procedure was 100% while using the flexcath steerable catheter in patients with the device perpendicular to the interatrial septum. There were no complica tions during the procedure. CONCLUSION: Percutaneous closure with FlexCath steerable catheter support in difficult cases with atrial septal defects was effective in those with the atrial septal closure device being per pendicular to the interatrial septum and was performed easily without any safety issues.
