The relationship between echocardiographic parameters and albumin bilirubin (ALBI) score in patients with isolated secundum type atrial septal defect.

BACKGROUND: It has been shown that the increase in volume and pressure in the right heart chambers increases liver stiffness. The Albumin-Bilirubin (ALBI) score is a useful and easy-to-use score for objectively assessing liver function. There is no information in the literature about changes in ALBI score in patients with atrial septal defect (ASD). The aim of our study is to investigate the changes in ALBI score and its clinical impact in patients with ASD. METHODS: Of the 206 analyzed patients, 77 were excluded. The remaining 129 patients with secundum type ASD with left to right shunt were divided into three groups; Group I (16 patients with Qp/Qs < 1.5 and defect diameter < 10 mm), Group II (52 patients with Qp/Qs > 1.5 and defect diameter 10-20 mm) and Group III (61 patients with Qp/Qs > 1.5 and defect diameter > 20 mm). The ALBI score was calculated based on serum albumin and total bilirubin levels using the following formula: ALBI = (log10 bilirubin [umol/L] * .66) + (albumin [g/L] * -.085). RESULTS: ALBI scores as well as total bilirubin levels, transaminases, and functional-structural heart abnormalities (increase in RA and RV dimensions, sPAP, ASD size and decrease in LVEF and TAPSE) showed a significant increasing trend from Group I to Group III (p < .001 for all comparisons). The mean ALBI scores for Group I, Group II, and Group III were -3.71 ± .37, -3.51 ± .25, and -3.27 ± .34, respectively. In multivariate linear regression analysis, ASD size, sPAP, RV-RA diameter were found to be significantly associated with increased ALBI score. CONCLUSION: The ALBI score offers a simple, evidence-based, objective, and discriminatory method of assessing liver function in patients with ASD. ASD size, sPAP, RV and RA diameters were significantly associated with ALBI score.

The association between the renal resistive index and the myocardial performance index in the general population.

OBJECTIVE: The renal resistive index (RRI) is the most described measure of renal hemodynamics. The myocardial performance index (MPI) is widely used to assess overall myocardial performance. In this study, we aimed to investigate the relationship between renal hemodynamics, assessed by the RRI, and cardiac functions, assessed by the MPI in the general population. METHODS: This single-center, cross-sectional study included a total of 302 consecutive patients who presented to our outpatient cardiology clinic between October 2019 and February 2020. All patients underwent transthoracic echocardiography and renal Doppler ultrasonography. The study population was divided into two groups: low RRI group (RRI ≤ 0.7, n = 236) and high RRI group (RRI > 0.7, n = 66). RESULTS: E/A ratio, left ventricular ejection fraction (LVEF), and the MPI were significantly higher in the high RRI group than in the low RRI group (61.3 ± 15.4 vs 55.3 ± 16.4, P = .010 for E velocity; 0.9 ± 0.3 vs 0.7 ± 0.2, P = .008 for E/A ratio; 57.7 ± 4.7 vs 53.2 ± 10.1, P = .029 for LVEF; 0.52 ± 0.1 vs 0.43 ± 0.1, P < .001 for the MPI). A stepwise linear regression analysis demonstrated that LVEF (ß = .123, P = .026), E velocity (ß = .221, P < .001), and the MPI (ß = .392, P < .001) were independently associated with the RRI. CONCLUSION: Left ventricular ejection fraction and intra-cardiac Doppler blood flow indices, including E velocity and the MPI, were significantly and independently associated with the RRI in the general population.

Increased frequency of fragmented QRS in patients with severe aortic valve stenosis.

OBJECTIVE: To investigate the presence of myocardial fibrosis determined by fragmented QRS in patients with severe aortic valve stenosis. SUBJECTS AND METHODS: Eighty-seven consecutive patients with severe aortic valve stenosis and 83 age- and gender-matched control subjects were enrolled into this study. Severe aortic valve stenosis was defined as an aortic valve area <1 cm(2), a Vmax >4 m/s, or a mean gradient ≥40 mm Hg. Fragmented QRS was assessed using a 12-lead electrocardiogram. RESULTS: Fragmented QRS was detected in 40 (46%) patients in the aortic valve stenosis group and in 15 (18%) control subjects (p < 0.001). In multivariate binary logistic regression analysis, the presence of aortic valve stenosis was the only independent factor associated with fragmented QRS (OR = 3.69; 95% CI 1.81-7.55, p < 0.001). CONCLUSION: A higher frequency of fragmented QRS was detected in patients with severe aortic valve stenosis compared to controls.

The Impact of Transcatheter or Surgical Defect Closure on Self-Reported Sleep Quality in Adults with Atrial Septal Defect.

OBJECTIVE: Sleep quality in those with cardiovascular disease is significantly lower than in the general population. This study aimed to explore the effect of transcatheter or surgical closure of atrial septal defect (ASD) on sleep quality. METHODS: One hundred nineteen adult patients with ASD who underwent transcatheter or surgical closure were included in the study. Sleep quality was investigated prospectively just before defect closure and six months after defect closure. Pittsburgh Sleep Quality Index (PSQI) was used to evaluate sleep quality of these patients. RESULTS: PSQI scores were similar in both groups before the procedure in patients who underwent both transcatheter and surgical closure. The PSQI scores six months after transcatheter closure was significantly improved compared to the PSQI score before transcatheter ASD closure (3.5 ± 2.0 vs. 6.9 ± 3.4, respectively; P<0.001). The PSQI scores six months after surgical ASD closure was significantly improved compared to the PSQI score before surgical closure (4.8 ± 2.1 vs. 7.1 ± 2.0, respectively; P<0.001). Total PSQI scores were also statistically different at six months after transcatheter and surgical closure (3.5 ± 2.0 vs. 4.8 ± 2.1, P=0.014). However, six months after both transcatheter and surgical closure, PSQI scores were significantly decreased in both groups which was more pronounced in patients who underwent transcatheter closure. CONCLUSION: Transcatheter or surgical closure of the defect may be beneficial in improving the sleep quality of adult patients with ASD. Delayed improvement of sleep quality after surgical closure may be an important advantage for transcatheter closure.

Assessment of transabdominal fat volumes as a predictor of prognosis in patients undergoing transcatheter aortic valve replacement.

Transcatheter aortic valve replacement (TAVR) has emerged as a well-established treatment option for eligible patients with severe aortic stenosis. This study aimed to investigate the correlation between abdominal fat tissue volumes, measured using computed tomography (CT), and all-cause mortality in patients undergoing TAVR. The study included 258 consecutive patients who underwent TAVR at a single center between September 2017 and November 2020. During the preoperative preparation, CT scans were used to perform a semi-quantitative measurement of abdominal fat components. Body mass index (BMI) for each participant was calculated. The relationship between fat parameters and overall survival was determined using multivariable Cox proportional hazards models. Participants had a mean age of 76.8 ± 7.8 years, of whom 32.9% were male. The median follow-up period was 12 months, during which 38 patients (14.7%) died. Both the survivor and non-survivor groups showed comparable risk factors. Regarding transabdominal fat volume parameters, deceased individuals exhibited significantly lower values. However, no significant differences were observed in BMI and transabdominal area measurements. Among transabdominal fat parameters, only subcutaneous fat volume [adjusted Hazard Ratio (aHR) = 0.83, p = 0.045] and total fat volume (TFV) [aHR = 0.82, p = 0.007] were identified as significant predictors of reduced all-cause mortality. Furthermore, TFV demonstrated the highest discriminative performance with a threshold of ≤ 9.1 L (AUC = 0.751, p < 0.001, sensitivity 71.1%, specificity 70.9%). Preoperative CT-based abdominal fat volume parameters, particularly TFV, can serve as potential predictors of survival in patients undergoing TAVR.

Real-Life Performance and Clinical Outcomes of Portico Transcatheter Aortic Valve with FlexNav Delivery System: One-Year Data from a Single-Center Experience.

Significant progress has been made in both valves and delivery systems (DSs) for transcatheter aortic valve replacement (TAVR) procedures. We aimed to present one-year real-life data regarding TAVR procedures using Portico transcatheter heart valves (THVs) with new-generation, low-profile FlexNav DSs. This retrospective, single-center study enrolled 169 consecutive patients (mean age: 75.8 years, 68% females) with severe aortic stenosis undergoing TAVR with Portico THVs and FlexNav DSs between 2020 and 2021. We evaluated safety and efficacy outcomes, following the VARC-3 consensus, periprocedurally and at 30 days and 1 year. Procedural success was observed in 95.9% of cases, and no procedural mortality occurred. At 30 days, the rates of all-cause mortality, cardiovascular mortality, and neurological events were 4.7%, 3.6%, and 3.0%, respectively. Additionally, major vascular complications, acute kidney injury, and bleeding were recorded at rates of 11.2%, 14.8%, and 7.7%, respectively. The 1-year data showed all-cause mortality, cardiovascular mortality, and neurological event rates of 10.7%, 8.3%, and 7.7%, respectively. The moderate paravalvular leak and permanent pacemaker rates at 1 year were 2.6% and 12.2%, respectively. This real-life data provided evidence of positive outcomes and high technical success with Portico THVs and FlexNav DSs. Furthermore, we found low rates of mortality and neurological events, with satisfactory hemodynamic and functional results.

Relationship Between Work Mode, Time of Admission, and Mortality in St-Segment Elevation Myocardial Infarction: Results From the TURKMI Registry.

Treatment of acute myocardial infarction has evolved steadily. However, limited studies exist regarding the effect of all innovations on mortality. We aimed to investigate the effect of time of admission and work mode on 1-year outcomes in patients presenting with ST-segment elevation myocardial infarction (STEMI). Based on the TURKMI registry, we analyzed 735 STEMI patients recruited consecutively and prospectively from 50 PCI-capable cardiology clinics within a prespecified two-week period. Centers were categorized as "on-call" and "on-duty" according to their work mode. At 1-year follow-up, all-cause mortality and cardiovascular mortality were the primary outcomes. The secondary outcome was a composite of coronary revascularization, re-infarction/stroke, and recurrent angina. One-fifth of the participants (19.5%) were treated in the on-call group. All-cause mortality (7.9 vs 10.5%, aHR: 1.16, P = .650) and cardiovascular mortality rates (6.1 vs 9.1%, aHR: 1.35, P = .413) were similar between centers' modes of work. Likewise, both groups were equally likely to undergo coronary revascularization (P = .278), re-MI/stroke (P = .280), recurrent angina (P = .175), and the composite outcome of these components (P = .482). No significant difference was observed in primary outcomes between weekend and weekday admissions. In conclusion, we observed similar outcomes between the on-call and on-duty groups among STEMI patients.

The value of PRECISE-DAPT score and lesion complexity for predicting all-cause mortality in patients with NSTEMI.

BACKGROUND: We aimed to evaluate the prognostic effects of stroke risk scores (SRS), SYNTAX score (SX score), and PRECISE-DAPT score on mortality in patients with non-ST-segment elevation myocardial infarction (NSTEMI). Three hundred forty-three patients hospitalized with a diagnosis of NSTEMI and underwent coronary angiography (CAG) between January 1, 2022, and June 1, 2022, were included retrospectively in this single-center study. Patients' demographic, clinical and routine biochemical parameters were recorded. The scores (CHADS2, CHA2DS2-VASc, R2CHA2DS2-VASc, ATRIA, SX score, PRECISE-DAPT) of each patient were calculated. Participants were then divided into two groups by in-hospital status; all-cause mortality (+) and all-cause mortality (-). RESULTS: Overall, the mean age was 63.5 ± 11.8 years, of whom 63.3% (n = 217) were male. In-hospital mortality occurred in 31 (9.3%) patients. In the study population, those who died had significantly higher SX (p < 0.001), PRECISE-DAPT (p < 0.001), and ATRIA (p = 0.002) scores than those who survived. In logistic regression analysis, PRECISE-DAPT score [Odds ratio (OR) = 1.063, 95% CI 1.014-1.115; p = 0.012] and SX score [OR: 1.061, 95% CI 1.015-1.109, p = 0.009] were found to be independent predictors of in-hospital all-cause mortality among NSTEMI patients. In ROC analysis, the PRECISE-DAPT score performed better discriminative ability than the SX score in determining in-hospital mortality [Area under the curve = 0.706, 95% CI 0.597-0.814; p < 0.001]. CONCLUSIONS: During the hospital stay, both PRECISE-DAPT and SX scores showed better performance than SRS in predicting all-cause mortality among NSTEMI patients undergoing CAG. Aside from their primary purpose, both scores might be useful in determining risk stratification for such patient populations.

The Relationship Between PRECISE-DAPT Score and Spontaneous Reperfusion of Infarct-Related Artery in Patients with ST-Segment Elevation Myocardial Infarction.

OBJECTIVE: Spontaneous reperfusion (SR) presence and a low PREdicting bleeding Complications In patients undergoing Stent implantation and subsEquent Dual Anti Platelet Therapy (PRECISE-DAPT) score in patients with acute coronary syndrome have been associated with favorable clinical outcomes. This study aimed to investigate the relationship between SR and this score. METHODS: The study included 436 patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI). Thrombolysis in myocardial infarction (TIMI) III blood flow presence in the infarct-related artery (IRA) before primary percutaneous coronary intervention (PCI) was defined as SR. Patients were categorized into two groups based on the presence (n = 49) or absence (n = 387) of SR. The PRECISE-DAPT score was computed for each patient using the web-based calculator. RESULTS: The group with SR had a lower frequency of hyperlipidemia and a higher ejection fraction (EF) at admission. Conversely, the group without SR presented with higher values of glucose, troponin, creatine kinase-myocardial band (CK-MB), and PRECISE-DAPT score. The no-reflow phenomenon and elevated SYNergy between PCI with TAXUS and Cardiac Surgery (SYNTAX-I) scores were higher in the group without SR than in the one with SR. Multivariate regression analysis indicated that a high PRECISE-DAPT score was an independent predictor of the absence of SR (odds ratio: 0.96, P = 0.04). CONCLUSION: The PRECISE-DAPT score is an independent predictor of the presence of spontaneous reperfusion in patients who experienced STEMI.

Anaphylactic shock due to intravenous amiodarone.

A 24-year-old male patient was admitted to the coronary intensive care unit with atrial fibrillation with rapid ventricular response. He was given amiodarone (Cordarone 150 mg i.v., Sanofi-Aventis) intravenous loading dose of 300 mg in 100 mL dextrose 5% in water (D5W) over 1 hour, followed by a maintenance dose of 900 mg in 500 mL D5W for infusion up to 24 hours. At the emergency department, the patient was conscious and cooperative; his pretreatment arterial blood pressure was 120/80 mm Hg, and the arrhythmic tachycardia was 145 per minute. After intravenous amiodarone loading and half an hour into maintenance infusion, extreme perspiration, hypotension (blood pressure immeasurable), and mild cyanosis developed. The patient was conscious; his auscultation and pulse were normal. He was given physiologic serum and dopamine support. Approximately an hour later, the blood pressure was measurable. Infusion was terminated because of suspicion of an allergic reaction to acetylsalicylic acid or amiodarone. The allergic reaction observed was attributed to acetylsalicylic acid and amiodarone; infusion was resumed when the clinical situation worsened during the maintenance infusion. Once again, the patient was given physiologic serum (2000 mL), dopamine (20 mg/kg per minute), and, additionally, 250 mg of methyprednisolone sodium succinate intravenous, whereby the clinical condition improved within 20 minutes. Anaphylactic shock cases due to amiodarone are rare; it is important to take a history of drug-mediated anaphylaxis before prescribing amiodarone. An addition to a review of the literature regarding treatment of amiodarone-related anaphylactic shock cases had not been reported before.

The impact of mitral stenosis on left atrial function assessed by two-dimensional speckle tracking echocardiography.

AIMS: The aim of this study is to investigate the effect of mitral stenosis (MS) on left atrial (LA) function using two-dimensional speckle tracking echocardiography (2DSTE). METHODS AND RESULTS: The study subjects consisted of 52 patients with asymptomatic MS and 52 control subjects. LA function was assessed using prototype speckle tracking software and manual tracking method. Maximal LA volume (LAVmax) and minimal LA volume (LAVmin) and LA volume before atrial contraction (LAVpre-a) were measured. Using these volumes, LA reservoir, conduit and booster pump fuction parameters were calculated. Indexed LAVmax, LAVmin, and LAVpre-a measurements via speckle tracking were highly correlated with manual tracing methods in both groups. Expansion index (67.8 ± 36.4 vs. 148.3 ± 44.2), diastolic emptying index (37.7 ± 12.9 vs. 58.0 ± 8.5), passive emptying (37.3 ± 14.1 vs. 70.4 ± 10.4) and passive emptying index (13.3 ± 6.3 vs. 41.3 ± 10.6) were decreased significantly in MS patients (P < 0.001). In contrast active emptying index (62.6 ± 4.1 vs. 29.5 ± 10.1) increased in MS group (P < 0.001) while active emptying (28.1 ± 13.0 vs. 28.3 ± 6.9) remained same among both groups. CONCLUSIONS: This is the first study relating LA volumes and function assessed by 2DSTE to MS. 2D speckle tracking analysis of LA volume is relatively easy and provides more detailed information regarding the changes in LA volumes during the cardiac cycle.

The association of dynamic thiol-disulphide balance with white-coat hypertension.

OBJECTIVE: Dynamic thiol-disulphide homeostasis is an indicator of the antioxidant system that interacts early with the oxidative environment. This study aimed to assess the dynamic thiol/disulphide balance in individuals with white-coat hypertension (WCH). METHODS: This cross-sectional study included a total of 117 individuals who presented to our outpatient cardiology clinic. Seventy patients were diagnosed with WCH. All blood samples were obtained from the patients after a minimum of 8 h of fasting, centrifuged immediately, stored in Eppendorf tubes, and protected at -80°C. RESULTS: The two groups were well-balanced in terms of age, gender, and BMI. Native thiol and total thiol levels were lower in the WCH group than in normotensive individuals. However, disulphide levels were higher in the former. Serum disulphide concentration positively correlated with 24-h SBP, and 24-h DBP. In backward stepwise logistic regression analysis, serum disulphide [odds ratio (OR) = 1.165 (1.089-1.245), 95% confidence interval (CI), P < 0.001] and serum total thiol levels [OR = 0.992 (0.984-1.000), 95% CI, P = 0.050] were independently associated with WCH. CONCLUSION: We demonstrated that dynamic thiol/disulphide balance shifted strongly towards disulphide formation due to thiol oxidation in patients with WCH.

HATCH Score for Predicting Mortality in COVID-19 Patients.

Background: We aimed to evaluate the relationship between HATCH score [hypertension, age >75 yr, previous transient ischemic attack (TIA) or stroke (doubled), chronic obstructive pulmonary disease, heart failure (doubled)] and in-hospital mortality in COVID-19 patients. Methods: Overall, 572 COVID-19 patients hospitalized between Mar 15 and Apr 15, 2020, were included in this multicenter retrospective study, in Turkey. The HATCH score of each patient was calculated. Mortality results were followed for 50 days. The patients were divided into 2 groups developing mortality (n=267) and non-mortality (n=305). Clinical outcomes were defined as in-hospital mortality improvement status. Results: HATCH scores in non-survivors of COVID-19 were significantly higher than in survivors (P<0.001). In logistic regression analysis, HATCH score (OR: 1.253, 95% CI: 1.003-1.565; P=0.047), platelet count (OR: 0.995, 95% CI: 0.993-0.998; P<0.001), C-reactive protein level (OR: 1.010, 95% CI: 1.007-1.013, P<0.001) and estimated glomerular filtration ratio (eGFR) level (OR: 0.963, 95% CI: 0.953-0.973; P<0.001) were independent predictors of in-hospital mortality in COVID-19 patients. Conclusion: The HATCH score is useful in predicting in-hospital mortality in patients hospitalized with COVID-19.

Association Between Morning Surge in Systolic Blood Pressure and SYNTAX Score I in Patients With Stable Coronary Artery Disease.

A high morning surge in systolic blood pressure poses a risk in people who have cardiovascular disease. We investigated the relationship between this phenomenon and the SYNTAX score I in patients who had stable coronary artery disease. Our single-center study included 125 consecutive patients (109 men and 16 women; mean age, 54.3 ± 9 yr) in whom coronary angiography revealed stable coronary artery disease. We calculated each patient's sleep-trough morning surge in systolic blood pressure, then calculated the SYNTAX score I. The morning surge was significantly higher in patients whose score was >22 (mean, 22.7 ± 13.2) than in those whose score was ≤22 (mean, 12.4 ± 7.5) (P <0.001). Forward stepwise logistic regression analysis revealed that morning surge in systolic blood pressure was the only independent predictor of an intermediate-to-high score (odds ratio=1.183; 95% CI, 1.025-1.364; P=0.021). To our knowledge, this is the first study to show an association between morning surge in systolic blood pressure and the SYNTAX score I in patients who have stable coronary artery disease.

Glasgow Prognostic Score as a Marker of Mortality after TAVI.

INTRODUCTION: The Glasgow prognostic score (GPS) reflects host systemic inflammatory response and has been reported to be significant as a prognostic indicator in cancer-bearing patients. The aim of this study was to evaluate the predictive value of GPS in outcomes of patients with severe aortic stenosis who were treated with transcatheter aortic valve implantation (TAVI). METHODS: The study population consisted of 79 patients who underwent TAVI due to severe aortic stenosis between January 2018 and March 2019 in our clinic. Echocardiographic and laboratory data were recorded before the procedure and GPS was scored as 0, 1, or 2, based on serum albumin and C-reactive protein levels. European System for Cardiac Operative Risk Evaluation II scoring system was used for risk stratification. The primary endpoints of the study were postoperative in-hospital mortality, hospitalization due to cardiac causes, or mortality within a year. RESULTS: The 79 patients were classified into two groups according to outcomes. Fifteen patients (19%) reached the primary endpoints at one year of follow-up. Compared to the patients who did not reach the endpoints, these 15 patients were not different in terms of age, preoperative mean gradient, and ejection fraction (P>0.05 for all). GPS was the only laboratory parameter with statistically significant difference between the groups (P=0.008) and multivariate analysis showed that GPS was independent predictor of primary endpoints (P=0.012, odds ratio 4.51, 95% confidence interval 1.39-14.60). CONCLUSION: GPS is an easy, noninvasive laboratory test which may be used as a predictive biomarker for outcomes in patients undergoing TAVI.

The relationship between serum rheumatoid factor level and SYNTAX score I in patients with acute myocardial infarction.

OBJECTIVE: Rheumatoid factor (RF) has been associated with an increased likelihood of developing coronary artery disease and cardiovascular mortality. This study aimed to evaluate the relationship between serum RF levels and SYNTAX score I (SSI) in patients with acute myocardial infarction. METHODS: This study included 418 consecutive patients who were diagnosed with acute myocardial infarction and underwent coronary angiography. The baseline serum RF levels of all patients were measured. The study population was divided into 2 groups, namely, ST-segment elevation myocardial infarction (STEMI) group (218 patients) and non-ST-segment elevation myocardial infarction (NSTEMI) group (200 patients). Each group was further divided into 2 subgroups, namely, SSI ≤22 group and SSI >22 group. RESULTS: In the STEMI group, RF levels were significantly higher in the SSI >22 group than that in the SSI ≤22 group (13.0 IU/mL [7.0-51.0 IU/mL] versus 11.0 IU/mL [4.0-37.0 IU/mL], respectively, p=0.002). In the NSTEMI group, RF levels were significantly higher in the SSI >22 group than that in the SSI ≤22 group (15.5 IU/mL [8.0-69.5 IU/mL] versus 13.0 IU/mL [4.0-36.0 IU/mL, respectively], p<0.001). Forward conditional logistic regression analysis demonstrated that neutrophil-to-lymphocyte ratio, total cholesterol level, positive RF, and left ventricular ejection fraction were independently associated with intermediate and high SSI in patients with STEMI. Furthermore, cardiac troponin T levels and positive RF were independently associated with intermediate and high SSI in patients with NSTEMI. CONCLUSION: Serum RF concentrations are independently associated with SSI in patients with acute myocardial infarction.

Impact of objective nutritional indexes on 1-year mortality after transcatheter aortic valve implantation: a prospective observational cohort study.

INTRODUCTION: The prognostic value of objective nutritional indexes has been demonstrated in many diseases. This study evaluated the prognostic value of these indexes in patients who underwent transcatheter aortic valve replacement (TAVI). MATERIAL AND METHODS: Totally, 119 consecutive patients who underwent TAVI between January 2016 and December 2018 were evaluated. All patients were followed-up for one year. Objective nutritional index (geriatric nutritional risk index [GNRI], prognostic nutritional index [PNI]) and controlling nutritional status [CONUT]) scores were calculated before TAVI. RESULTS: Mean age of the study population was 77.1 ± 7.8 years (59.7% female). During one-year follow-up, 31 (26.1%) deaths were observed. In a Kaplan-Meier analysis, mortality rates were significantly increased in patients with lower GNRI and PNI and higher CONUT scores (50.01% vs. 4.4%; p < .001, 48.1% vs. 15.2%; p < .001, 57.5% vs. 12.8%; p < .001, respectively). Pairwise comparisons of the ROC curves demonstrated that the GNRI score was a significantly better predictor of mortality than the PNI and CONUT scores (area under curve; 0.898, 0.664, and 0.722, respectively, for both; p < .001). According to Cox proportional hazard analyses, the GNRI (hazard ratio [HR]: 0.898) and STS (HR: 1.359) score were independently associated with increased 1-year mortality (for all p < .05). CONCLUSION: The GNRI, PNI and CONUT scores were associated with 1-year all-cause mortality in patients who underwent TAVI. The predictive value of the GNRI score was significantly better than the PNI or CONUT scores. Assessment of the GNRI should be considered before TAVI.

The Impact of Transcatheter Aortic Valve Implantation (TAVI) on Serum Apelin Levels in Patients with Aortic Valvular Stenosis.

INTRODUCTION: In this study, we aimed to investigate the impact of transcatheter aortic valve implantation (TAVI) on serum apelin levels in patients with severe symptomatic aortic valve stenosis (AS). METHODS: Forty-six consecutive patients (76.9±7.4 years, n=27 women) who underwent TAVI and 45 age- and sex-matched control subjects were included in the study. Echocardiographic parameters, serum apelin, pro-brain natriuretic peptide (Pro-BNP), and troponin I levels were compared between the groups. In addition, the preprocedural and first-month follow-up echocardiographic parameters and serum apelin values of TAVI patients were compared. RESULTS: Serum median troponin I and Pro-BNP levels were significantly higher and serum apelin levels were significantly lower in TAVI patients before TAVI procedure than in the control subjects (P<0.001, for all). Median troponin I and Pro-BNP levels were significantly decreased and apelin levels were significantly increased after TAVI procedure compared to the peri-procedural levels. There was a significant and moderate negative correlation between Pro-BNP and apelin levels measured before and after TAVI procedure. A statistically significant and strong negative correlation was found between aortic valve area and Pro-BNP level before TAVI procedure, while a statistically significant but weak positive correlation was found between valve area and apelin level. CONCLUSION: In our study, apelin levels were significantly lower and Pro-BNP levels were higher in AS patients compared with the control group. Moreover, after TAVI procedure, a significant increase in apelin levels and a significant decrease in Pro-BNP levels were observed. There was also a negative and moderate correlation between apelin and Pro-BNP levels.

Post transcatheter aortic valve replacement ejection fraction response is predictor of survival among patients with whole range of systolic dysfunction.

AIMS: The objective of this study is to assess the prognostic effects of T ranscatheter aortic valve replacement (TAVR) on the patients with different degrees of left ventricular systolic (LVS) function and severe symptomatic aortic stenosis. Also examines the prognostic association of LV remodelling after TAVR. METHODS AND RESULTS: Patients stratified into four subgroups with respect to baseline LV ejection fraction (LVEF) (LVEF > 25%, LVEF 25%-40%, LVEF 41%-49% and LVEF ≥ 50%). We compared the baseline characteristics and temporal changes in echocardiographic parameters of the patients after TAVR, and determined all-cause mortality (ACM) in a follow-up period of mean 20.7 ± 15.8 months (up to 84). There were 495 patients at 8 centres. ACM was similar in all groups (28.1%, 29.5%, 22.5% and 24.1% respectively; p = .44). Immediately after TAVR, there was an improvement in LVEF (from 38.7 ± 9.4 to 44.9% ± 10.9%, p < .001). The percent change in LVEF (pDelta-EF) immediately after TAVR was more prominent in the patients with LVEF < 25% (48.1 ± 49.6, 21.9 ± 29.6), (8.4% ± 15.2%) and (2.1 ± 7)) (p < .01). Importantly, a 12% increase in absolute Delta-EF was observed in patients with LVEF< 25% with 100% sensitivity and 42.5% specificity for the prediction of ACM. CONCLUSION: This study shows that TAVR is beneficial in the whole range of LVS function, irrespective of the baseline EF. Early recovery in LVEF after TAVR is critical for survival, however, it seems to be more eye catching in the patients with advanced heart failure with reduced EF.

Short-term effect of levosimendan on free light chain kappa and lambda levels in patients with decompensated chronic heart failure.

To investigate the effects of levosimendan, a positive inotropic agent, on the new heart failure markers immunoglobulin free light chains kappa and lambda (FLC-kappa and FLC-lambda) in decompensated chronic heart failure (HF), 59 patients with New York Heart Association (NYHA) class III-IV HF were enrolled. Patients were randomized into levosimendan (n = 31) and standard HF treatment (n = 29) groups. Serum FLC-kappa and FLC-lambda, brain natriuretic peptide (BNP), and ejection fraction (EF) were measured before treatment and on the 5th day of treatment initiation. Forty-two percent of subjects were females (n = 25) and overall mean age was 64.1 +/- 10.7 years. FLC-kappa (P < 0.05) and FLC-lambda (P < 0.05) were significantly decreased in the levosimendan group compared to baseline, but no difference in either marker in the standard treatment group was observed. Pre- and post-treatment FLC-kappa/FLC-lambda ratios in both groups were similar, whereas FLC-kappa and FLC-lambda levels and the FLC-kappa/FLC-lambda ratio showed no significant correlation with NYHA class, brain natriuretic peptide (BNP) and ejection fraction (EF) levels; and BNP and EF changes after the treatment. Symptomatic improvement in the levosimendan group according to the NYHA class was significantly better than in the standard treatment group (P = 0.044). While 55.2% of patients in the levosimendan group showed a 1-degree shift to lower NYHA classes, 10.3% showed a 2-degree decrease. In conclusion, levosimendan caused short-term hemodynamic and symptomatic improvements, with a more pronounced decrease in FLC levels in patients with advanced decompensated HF.
