RESUMEN
PURPOSE: The presence of right ventricular dysfunction indicates a higher risk status in patients with pulmonary embolism (PE). The RV strain evaluated by speckle-tracking echocardiography seems to be more reliable method in the evaluation of RV dysfunction as compared to standard echocardiographic measures. In this study, we aimed to determine the value of myocardial-work indices in evaluating serial changes of RV function in acute PE. METHODS: Our study comprised 83 consecutive acute PE patients who admitted to our tertiary cardiovascular hospital. Echocardiography was performed within the first 24-hours of hospitalization, and RV and LV myocardial-work parameters were obtained along with standard echocardiographic parameters. The change in the RV/LVr detected on tomography was selected as the primary outcome measure, and its' predictors were analyzed with classical linear regression and a generalized additive model (GAM). RESULTS: Among the LV-RV strain and myocardial work parameters, the RV global longitudinal strain (GLS) has borderline statistical significance in predicting the RV/LVr change whereas the RV global work efficiency (RV-GWE) strongly predicted RV/LVr change (p: 0.049 and <0.001, respectively). CONCLUSION: In this study, classical linear regression and GAM analyses showed that RV-GWE seems to offer a better prediction of RV/LVr change in patients with acute PE.
RESUMEN
Introduction: Pericardial drainage can be performed either with pericardiocentesis or pericardial "window" in cases with hemodynamic compromise for therapeutic and diagnostic purposes. Awake single-port video-assisted thoracoscopic surgery (VATS) is an alternative to pericardial window (PW) that has been described only in case reports in the literature. We aimed to analyse a series of patients with chronic, recurrent and/or large pericardial effusions who underwent single-port VATS-PW opening without intubation. Patients and Methods: The PW was opened using awake single-port VATS in 20 of 23 patients referred to our clinic with recurrent, chronic and/or large pericardial effusion between December 2021 and July 2022. Demographic data, imaging modalities, treatment processes and pathological samples were analysed retrospectively. Results: The median age of 20 patients was 68 years (52-81). The mean body mass index was 29.1 ± 6.0 kg/m2 and mean pericardial fluid measurements with pre-operative transthoracic echocardiography (TTE) was 2,8 ± 0,9 cm. The mean operation time was 44 ± 13.0 min and mean peri-operative drainage was 700 ± 307 cc. On the 1st post-operative day, control TTE revealed ≤0.5 cm effusion in 18 (90%) patients and ≥0.5 cm in 2 (10%) patients. The median day of discharge or referral to the clinic where they are followed up was 1 (1-2). Conclusions: Awake single-port VATS could be used safely in all patient groups with pericardial effusion or tamponade as a diagnostic and therapeutic option. This technique has advantages, especially in patients with high surgical risk.
RESUMEN
A 34-year-old male with incessant drug-refractory atrial tachycardia (AT) was referred to our clinic for catheter ablation. The procedure began with endocardial activation mapping. The earliest endocardial activation site was in the right atrial appendage (RAA). The procedure continued with mapping of the left atrium through a transseptal approach. The earliest local activation was recorded at the anterior site of the right pulmonary veins. Radiofrequency (RF) ablation of both localizations was performed synchronously but failed to terminate the arrhythmia. The procedure continued with isolation of the RAA using cryoballoon but failed again due to the anomalous structure of the RAA. Then, epicardial RF ablation was attempted but failed. Finally, AT could only be terminated by surgical excision of the RAA.

BACKGROUND: Isolated pulmonary valve endocarditis is extremely rare, accounting for <2% of cases. Major predisposing factors are intravenous drug use, implanted cardiac devices, congenital heart diseases, and central venous catheters. Most patients respond well to appropriate antibiotherapy. AIM: We report a case with an isolated native pulmonary valve endocarditis due to methicillin-resistant staphylococcus-aureus infection which developed after a tooth abscess in a previously healthy non-drug user young male. After one week antibiotherapy, surgery was required due to acute severe pulmonary insufficiency and right heart-failure. After the operation, he had a multi-organ failure despite veno-arterial extracorporeal membrane oxygenation, antibiotherapy, and other supportive treatments, therefore the case concluded with mortality. DISCUSION AND CONCLUSION: Our case showed that pulmonary valve endocarditis may occur in patients without risk factors in case of portal of entry for bacteremia and it may carry worse prognosis than previously known. Virulence of the microorganism and vegetation size are the major predictors of prognosis. Pulmonary valve endocarditis should be kept in mind even in patients without any known risk factors.

Bidirectional ventricular tachycardia (BVT) is a rare arrhythmia that is generally observed in patients with catecholaminergic ventricular tachycardia or digoxin overdose. Herein, we present a case of BVT and electrical storm (ES) in an acute ischemic heart failure patient that is typically induced by hypokalemia. The patient was in invasive mechanical ventilator (MV) support and hypokalemia was related to acute respiratory alkalosis and that caused refractory hypokalemia despite intravenous (IV) potassium replacement. We also discuss our approach to solve refractory hypokalemia caused by respiratory alkalosis.

BACKGROUND: The aim of this study was to explore the role of oxidative stress index (OSI), myeloperoxidase (MPO), and catalase (CAT) activity in cardiac allograft vasculopathy (CAV) in heart transplant recipients (HTRs). METHODS: The study enrolled a median age of 41 ± 9 years 47 recipients. The HTx patients were divided into two groups based on the presence CAV as follows: CAV(+) and CAV(-) group. Also, CAV(+) group were divided into two groups as mild/moderate to severe CAV. The OSI, MPO, and CAT activity were analyzed in both groups. RESULTS: The mean total antioxidant capacity (0.79 ± 0.46 vs 1.03 ± 0.33 µmol H2 O2 equiv/L) P = .043 was significantly lower and OSI, MPO, CAT activity were significantly higher in CAV(+) group (63 ± 38 vs 20 ± 16 arbitrary unit, P = .001; 398 ± 242 vs 139 ± 112 µg/L, P = .001; 51 ± 42 vs 26 ± 23 pmol/mg protein, P = .013, respectively). Also, mean OSI (38 ± 41 vs 93 ± 75, P = .05) were significantly higher in severe CAV(+) group. Recipient age, male gender, and low density lipoprotein-cholesterol were significantly higher in CAV(+) group. There was a moderate correlation between the CAV grade and OSI, MPO, and CAT levels in univariate analysis (r = .560, P = .002; r = .643, P = .007; r = .681, P = .001, respectively). CONCLUSION: An increase in the serum level of OSI, MPO, and CAT was associated with CAV in HTRs.

BACKGROUND: The use of the CHA2DS2-VASc scoring system and red cell distribution width (RDW) as post-op Atrial Fibrillation (POAF) predictors may be promising for the identification of patients that are at a higher risk of POAF. METHODS: A total of 358 patients (57 patients with POAF, and 301 patients with non-POAF ) with sinus rhythm undergoing a coronary artery bypass graft (CABG) operation were included in the study retrospectively. Preoperative RDW levels and electrocardiograms with sinus rhythm were recorded. Patients with at least one 12-lead electrocardiogram with atrial fibrillation in the postoperative period, with or without medical or electrical cardioversion, were considered to have postoperative atrial fibrillation. A CHADS2 and CHA2DS2-VASc score was calculated for all of the patients. RESULTS: RDW levels were significantly higher in POAF group. RDW levels were significantly correlated with CHADS2 ( r = 0.15, P = .007) and CHA2DS2-VASc (r = 0.19 P = .0001) scores. CHA2DS2-VASc scores were significantly higher in patients with POAF, whereas CHADS2 scores did not differ between groups. In multivariate analysis, left atrial diameter (LAD) (OR:2.44 [95% CI 1.16 - 5.1], P = .018), age (OR:1.04 [95% CI 1.01 - 1.08], P = .01), and RDW (OR:1.16 [95% CI 1.0 - 1.36], P = .05) were found to be predictive for POAF. The area under the receiver-operating characteristic curve of RDW was 0.65 (0.57 - 0.72, P = .0001) with 68.4% sensitivity and 51.2 % specificity to predict POAF. CONCLUSION: Our study showed that age, LAD, and the reduced probability of RDW are predictors of POAF, and that RDW is strongly associated with the thromboembolic risk as determined by CHADS2 and CHA2DS2-VASc scores.

BACKGROUND: The aim of this study was to assess whether epicardial fat thickness (EFT) is associated with the severity of heart failure in patients with nonischemic dilated cardiomyopathy (NICMP). METHODS: The study group was composed of 93 patients with NICMP and38 age- and sex-matched healty individuals as the control group. The EFT was identified during end-systole at the point on the free wall of the right ventricle. RESULTS: Patients with NICMP had significantly lower mean EFT than those in the control group (4.1 ± 0.8 vs. 6.1 ± 1.8 mm, P < 0.001). EFT was thinnest in patients with New York Heart Association (NYHA) functional class III or IV (3.5 ± 0.5, P < 0.001). There was a significant correlation between EFT, left ventricle EF (r = 0.540 P < 0.001), and B-type natriuretic peptide (BNP) (r = -0.695, P < 0.001) values in patients with NICMP. In addition, when EFT was corrected for BMI, EFT/BMI was lower in patients with NYHA functional class III-IV than patients with NYHA class I-II and control group (0.13 ± 0.01, 0.16 ± 0.02, 0.23 ± 0.04, respectively; P < 0.001). There was a significant correlation between EFT/BMI, left ventricle EF (r = 0.489, P < 0.001), and BNP (r = -0.549, P < 0.001) in patients with NICMP. In multivariate regression analysis, EFT (P = 0.009), BNP (P = 0.039), and left atrium volume index (P = 0.039) were independently associated with impaired functional status. CONCLUSION: Echocardiographic EFT is an inexpensive, simple, and readily available marker that may be used to asses the severity of chronic heart failure in patients with NICMP.

BACKGROUND: Currently available risk stratification models for acute pulmonary embolism (PE) include hemodynamic status, cardiac biomarkers, right ventricle (RV) dysfunction on imaging, and clinical scores. Focusing on the length-tension relationship of the ventricle might have a superior predictive capability over RV dysfunction in terms of mortality and classification of patients with acute PE. In this study, our hypothesis suggests that the tricuspid annular plane systolic excursion (TAPSE)/systolic pulmonary artery pressure (sPAP) ratio has superior predictive capability for in-hospital mortality in patients with acute PE compared to TAPSE or sPAP as distinct measures. METHODS: This single-center study comprised retrospectively evaluated 703 patients referred to our tertiary cardiovascular center with acute PE. We divided patients into quartiles based on the TAPSE/sPAP ratio. Different models were developed to quantify the predictive relationship between in-hospital death and echocardiographic measurements. A base model was created with variables including risk status and RV/LV ratio >1. Then, to evaluate the predictive contribution of each measurement; TAPSE/sPAP, TAPSE, and sPAP were sequentially added to the base model. After that, the performance of each model was evaluated. RESULTS: Predictive and discriminative power was the highest in model containing TAPSE/sPAP. There was still a significant inverse association between TAPSE/sPAP and the risk of in-hospital death even after adjusting for risk status and RV/LV ratio >1. Receiver operating characteristic curve analysis for TAPSE/sPAP revealed the best cut-off value as 0.34. CONCLUSION: The outcomes of our study reveal that the ratio of TAPSE/sPAP serves as a more potent predictor of mortality than either of the 2 measurements taken separately. The interpretation and utilization of the TAPSE/sPAP cut-off value in acute PE can assist in identifying patients at risk of deterioration and guide the consideration of more intensive treatment options across all risk groups.
RESUMEN
BACKGROUND: AngioJet rheolytic thrombectomy (ART) system has been widely used as a catheter-directed treatment (CDT) method in acute pulmonary embolism (PE), however, there has been a controversy regarding the safety of its use. In this systematic review and meta-analysis, we evaluated the efficacy and safety outcomes of ART in patients with PE. METHODS: Our meta-analysis have been based on search in the MEDLINE, EMBASE, and Cochrane Library for studies published up to August 2022. The primary outcomes were overall pooled rates of major bleeding (MB) and minor bleeding (mB), worsening renal function (WRF), bradycardia/conduction disturbance (BCD), and PE-related and all-cause mortality in patients who underwent ART. RESULTS: Among the 233 studies documented at initial search, 24 studies were eligible for meta-analysis, and a total of 427 PE patients who underwent ART were evaluated. Overall pooled rates of MB and mB were 9.6% (95% CI 5.9%-15.2%) and 9.2% (95% CI 6.1%-13.6%), transient BCD and WRF were 18.2% (95% CI 12.4%-26%) and 15% (95% CI 10%-21.8%), and PE-related death and all-cause death were 12.7% (95% CI 9.1%-17.3%) and 15% (95% CI 11%-20%), respectively. However, significant heterogeneity and some evidence of funnel plot asymmetry and publication bias were noted for MB, BCD and WRF, but not for PE-related death and all-cause death. CONCLUSION: Overall pooled rates of bleeding events, BCD and WRF episodes, PE-related death and all-cause death may be considered as encouraging results for efficacy and safety issues of ART utilization in specific scenarios of acute PE, and a reappraisal for black-box warning on ART seems to be necessary.
RESUMEN
OBJECTIVE: Pulmonary artery (PA) enlargement is a common finding in patients with severe pulmonary hypertension (PH) and may be associated with extrinsic compression of the left main coronary artery (LMCA-Co) and/or compression of the left recurrent laryngeal nerve resulting in hoarseness named as Ortner syndrome (OS). In this study, we evaluated the diagnostic impact of OS in predicting the PA aneurysm and significant LMCA-Co in patients with PH. METHODS: Our study population comprised retrospectively evaluated 865 with PH confirmed with the right heart catheterization between 2006 and 2022. Patients underwent coronary angiography due to several indications, including the presence of a PA aneurysm on echocardiography, angina symptoms, or the incidental discovery of LMCA-Co on multidetector computed tomography. The LMCA-Co is defined as diameter stenosis ³ 50% in reference distal LMCA segment on two consecutive angiographic planes. RESULTS: The LMCA-Co and hoarseness were documented in 3.8% and 4.3% of patients with PH, respectively. Increasing PA diameter was significantly associated with worse clinical, hemodynamic, laboratory, and echocardiographic parameters. The receiver operating curves revealed that the PA diameter >41 mm was cutoff for hoarseness (AUC: 0.834; sensitivity 69%, specificity 84%, and negative predictive value 98%), and PA diameter >35 mm was cutoff for LMCA-Co >50% (AUC: 0.794; sensitivity 89%, specificity 58 %, and negative predictive value 99%). An odds ratio of hoarseness for LMCA-Co was 83.3 (95% confidence interval; 36.5-190, P < 0.001) with 3.2% sensitivity, 98.7% specificity, and 59% positive and 98% negative predictive values. CONCLUSION: In this study, a close relationship was found between the presence of hoarseness and the probability of extrinsic LMCA-Co by enlarged PA in patients with severe PH. Therefore, the risk of LMCA-Co should be taken into account in patients with PH suffering from hoarseness.

BACKGROUND: Pulmonary embolism severity index and simplified pulmonary embolism severity index have been utilized in initial risk evaluation in patients with acute pulmonary embolism. However, these models do not include any imaging measure of right ventricle function. In this study, we proposed a novel index and aimed to evaluate the clinical impact. METHODS: Our study population comprised retrospectively evaluated 502 patients with acute pulmonary embolism managed with different treatment modalities. Echocardiographic and computed tomographic pulmonary angiography evaluations were performed at admission to the emergency room within maximally 30 minutes. The formula of our index was as follows: (right ventricle diameter × systolic pulmonary arterial pressure-echo)/(right ventricle free-wall diameter × tricuspid annular plane systolic excursion). RESULTS: This index value showed significant correlations to clinical and hemodynamic severity measures. Only pulmonary embolism severity index, but not our index value, independently predicted in-hospital mortality. However, an index value higher than 17.8 predicted the long-term mortality with a sensitivity of 70% and specificity of 40% (areas under the curve = 0.652, 95% CI, 0.557-0.747, P =.001). According to the adjusted variable plot, the risk of long-term mortality increased until an index level of 30 but remained unchanged thereafter. The cumulative hazard curve also showed a higher mortality with high-index value versus low-index value. CONCLUSIONS: Our index composed from measures of computed tomographic pulmonary angiography and transthoracic echocardiography may provide important insights regarding the adaptation status of right ventricle against pressure/wall stress in acute pulmonary embolism, and a higher value seems to be associated with severity of the clinical and hemodynamic status and long-term mortality but not with in-hospital mortality. However, the pulmonary embolism severity index remained as the only independent predictor for in-hospital mortality.

BACKGROUND: Although an adopted echocardiography algorithm based on tricuspid regurgitation jet peak velocity and suggestive findings for pulmonary hypertension has been utilized in the non-invasive prediction of pulmonary hypertension probability, the reliability of this approach for the updated hemodynamic definition of pulmonary hypertension remains to be determined. In this study, for the first time, we aimed to evaluate the tricuspid regurgitation jet peak velocity and suggestive findings in predicting the probability of pulmonary hypertension as defined by mean pulmonary arterial pressure > 20 mm Hg and > 25 mm Hg, respectively. METHODS: Our study group was comprised of the retrospectively evaluated 1300 patients (age 53.1 ± 18.8 years, female 62.1%) who underwent right heart catheterization with different indications between 2006 and 2018. All echocardiographic and right heart catheterization assessments were performed in accordance with the European Society of Cardiology/European Respiratory Society 2015 Pulmonary Hypertension Guidelines. RESULTS: Although tricuspid regurgitation jet peak velocity showed a significant relation with mean pulmonary arterial pressure in both definitions, suggestive findings offered a significant contribution only in predicting mean pulmonary arterial pressure ≥ 25 mm Hg but not for mean pulmonary arterial pressure > 20 mm Hg. In predicting the mean pulmonary arterial pressure > 20 mm Hg, tricuspid regurgitation jet peak velocity and suggestive findings showed an odds ratio of 2.57 (1.59-4.14, P <.001) and 1.25 (0.86-1.82, P =.16), respectively. In predicting the mean pulmonary arterial pressure ≥ 25 mm Hg, tricuspid regurgitation jet peak velocity, and suggestive findings showed an odds ratio of 2.33 (1.80-3.04, P <.001) and 1.54 (1.15-2.08, P <.001), respectively. The tricuspid regurgitation jet peak velocity > 2.8 m/s and tricuspid regurgitation jet peak velocity > 3.4 m/s were associated with 70% and 84% probability of mean pulmonary arterial pressure > 20 mm Hg and 60% and 76% probability of mean pulmonary arterial pressure ≥ 25 mm Hg, respectively. CONCLUSIONS: In contrast to those in predicting the mean pulmonary arterial pressure ≥ 25 mm Hg, suggestive findings did not provide a significant contribution to the probability of mean pulmonary arterial pressure > 20 mm Hg predicted by tricuspid regurgitation jet peak velocity solely. The impact of the novel mean pulmonary arterial pressure threshold on the echocardiographic prediction of pulmonary hypertension remains to be clarified by future studies.

BACKGROUND: A subset ofpatients found to have total occlusion of the culprit artery (TOCA), present with non-ST-segment elevation myocardial infarction (NSTEMI) and elevated biomarkers. The aim of this study is to assess the effect of the TOCA in patients presenting with NSTEMI. METHODS: This multicenter observational study was retrospectively conducted between 2015 and 2019. Thrombolysis in myocardial infarction (TIMI) flow grades 0-1 was defined as the TOCA. The primary end point included a combination of all-cause death, myocardial infarction, target vessel revascularization, stent thrombosis, and stroke. RESULTS: Of 3272 patients, TIMI 0-1 flow in the culprit artery was present in 488 (14.9%) patients. TOCA was more likely to be of thrombotic origin (54.1% vs. 10.3%; P < 0.001) and visible collaterals (22.5% vs. 4.4%; P < 0.001). The rates of 30-day (14.3% vs. 7.2%; P < 0.001) and 2-year (25% vs. 19.1%; P = 0.003) primary end points were significantly higher in TOCA patients. Fatal arrhythmias were remarkably higher at 30-day (8.6% vs. 4%; P < 0.001) and 2-year (9% vs. 5.2%; P = 0.001) follow-ups. Mechanical complications were also higher in patients with TOCA at 30 days (0.8% vs. 0.2%; P = 0.013). Moreover, TOCA (OR, 1.379; P = 0.001) was one of the independent predictors of MACCE in NSTEMI patients. CONCLUSION: The current data suggest that patients with TOCA in the context of NSTEMI are at higher risk of MACCE, fatal arrhythmias, and mechanical complications.

BACKGROUND: We evaluated the predictive value of electrocardiographic (ECG) findings for pulmonary hemodynamics assessed by right heart catheterization (RHC). METHODS: Our study population comprised 562 retrospectively evaluated patients who underwent RHC between 2006 and 2022. Correlations between ECG measures and pulmonary arterial systolic and mean pressures (PASP and PAMP) and pulmonary vascular resistance (PVR) were investigated. Moreover, receiver operating characteristic (ROC) curve analysis assessed the predictive value of ECG for pulmonary hypertension (PH) and precapillary PH. RESULTS: The P-wave amplitude (Pwa) and R/S ratio (r) in V1 and V2, Ra in augmented voltage right (aVR), right or indeterminate axis, but not P wave duration (Pwd) or right bundle branch block (RBBB) significantly correlated with PASP, PAMP, and PVR (P <.001 for all). The partial R2 analysis revealed that amplitude of R wave (Ra) in aVR, R/Sr in V1 and V2, QRS axis, and Pwa added to the base model provided significant contributions to variance for PASP, PAMP, and PVR, respectively. The Pwa > 0.16 mV, Ra in aVR > 0.05 mV, QRS axis > 100° and R/Sr in V1 > 0.9 showed the highest area under curve (AUC) values for PAMP > 20 mm Hg. Using the same cutoff value, Ra in aVR, Pwa, QRS axis, and R/Sr in V1 showed highest predictions for PVR > 2 Wood Units (WU). CONCLUSION: In this study, Pwa, Ra in aVR, right or indeterminate axis deviations, and R/Sr in V1 and V2 showed statistically significant correlations with pulmonary hemodynamics, and Ra in aVR, R/Sr in V2 and V1, QRS axis, and Pwa contributed to variance for PASP, PAMP, and PVR, respectively. Moreover, Pwa, Ra in aVR, QRS axis, and R/Sr in V1 seem to provide relevant predictions for PH and precapillary PH.

OBJECTIVE: Parallel to the aging of the world population, the complexity of patients with cardiac problems has increased, especially in intensive cardiology care units, and the importance of multidisciplinary care has become more evident. The aim of this study was to analyze the clinical characteristics and gender-related differences of patients hospitalized in a large intensive cardiology care unit. METHODS: This single-center, retrospective, cross-sectional study includes all hospitalizations in a large intensive cardiology care unit between January 2016 and March 2021. All data were obtained using data collection software and transferred to MEDULLA, Turkey's general database system. RESULTS: Of the 55 737 consecutive patients included in the analysis, 16342 (29%) were women. The mean age of males was 59.71 ± 12 years, and the mean age of females was 63.3 ± 14 years (P <.001). Over a period of 5 years, the most common reason for hospitalization in the intensive cardiac care unit was acute coronary syndrome. The number of acute coronary syndrome patients who underwent coronary angiography was found to be 17 478 (31%), of which 12 878 were males and 26.3% were female. The number of patients who underwent at least 1 stent implantation was 13 952 (80% of coronary angiography procedures), and 2960 (21%) were women. The second cause of hospitalization in the intensive cardiology care unit was arrhythmias (5654 patients [10%]) followed by advanced heart failure (932 patients [1.7%]). During follow-up in the intensive cardiology care unit, the percentage of development of multiorgan failure was found to be approximately 18%. The mortality rate was 7% in women, which was higher than in men (4%). While the most common cause of death was acute coronary syndrome, the highest rate of death was found in patients with advanced heart failure. Among the patients who died, the mean age of females was higher than that of males, and the length of hospital stay was longer. CONCLUSION: Although numerically the highest death rate was observed in male acute coronary syndrome patients, the highest mortality rate was found in patients with advanced heart failure. Due to the elderly population and the increase in the number of patients requiring multidisciplinary treatment, the development of multiorgan failure in intensive cardiology care units seems to be one of the most important causes of death. Although the number of females hospitalized in the intensive cardiology care unit is lower than that of males, the mean age and mortality rate were found to be higher than males.

BACKGROUND: Acute type A aortic dissection (ATAAD) is one of the most mortal cardiovascular diseases and requires urgent diagnosis and surgery. The patient's clinical findings, complications, and patient's history are closely related to mortality rates. Cardiac surgery score (CASUS) is a scoring system which is calculated by considering the special pathophysiological conditions of patients undergoing cardiac surgery and predicts post-operative results with high accuracy. METHODS: Following the ethical approval from institutional ethics committee (ID: 2021/7/496), the data of consecutive 50 ATAAD patients who underwent emergent surgery in our hospital between January 1, 2019, and December 31, 2020, were evaluated. The Sequential Organ Failure Assessment and CASUS scores were calculated using the worst values of the daily laboratory and neurological status for both in admission to emergency department and during intensive care unit (ICU) follow-up period. The average and the total values of these scores were recorded for pre-operative, post-operative 1st day, and for the categorical data were defined as frequency and percentage. We used the Mann-Whitney U test for the independent continuous data comparisons and Pearson Chi-Square or Fisher exact test for categorical data comparison whole ICU period. Continuous data were presented as median and interquartile ranges (25-75th). RESULTS: The study comprised 50 patients, the rate of death was 34% (n=17). In total group, there were hypertension 72% (n=36), diabetes mellitus 24% (n=12), initial hemoglobin 12.5 g/dL (10.7-14.1, 25-75th), creatinine 1.09 mg/dL (0.85-1.33, 25-75th), and 72% (n=36) of these patients were male. The CASUSmean and SOFAmean scores were higher in the death-group when compared with the group who survived (12.9 [9.5-13.8, 25-75th], 3 [2-5, 25-75th]; 8 [6.1-9.2, 25-75th], 2.6 (2-4.5, 25-75th], p<0.001, respectively]. CASUSmean was independently associated with the 1-month mortality in model 1 (HR 1.25 [1.14-1.37] (p<0.001). CONCLUSION: According to our results increase in CASUS mean was the main predictor of 1 month mortality. When CASUS mean exceeds 8.3 the patient should be followed up more carefully for major adverse events including death.

BACKGROUND: Left ventricular systolic dysfunction (LVSD) may develop without coronary artery disease, hypertension (HT), or valvular pathologies in patients with diabetes mellitus (DM), which is defined as diabetic cardiomyopathy (DCM) and its pathophysiology is still unclear. Diabetic retinopathy (DR) is a microvascular complication of DM, and patients with DR have increased risk for the development of heart failure (HF). Two-dimensional speckle tracking echocardiography (2D-STE) evaluates longitudinal deformation in left atrium (LA) myocardium and previous studies utilizing 2D-STE have revealed the detrimental effects of DM on LA functions. Although some studies have shown the association between DR and left ventricle (LV) systolic functions, as far as the researchers of this study investigated, there is no study evaluating the relationship between LA deformation parameters and DR. Hence, we aimed to investigate the relationship between the presence and the degree of DR and LA deformation parameters. RESULTS: LA deformation parameters were analyzed in terms of LA reservoir, conduit, and contractile functions according to the degree of DR. LA reservoir strain value was 14.2 ± 3.6 in normal retina group, 12.2 ± 4.1 in non-proliferative diabetic retinopathy (NPDR) group, and 13 ± 3.7 in proliferative diabetic retinopathy (PDR) group (P = 0.04). LA contractile strain was 15.9 ± 6.8 in normal retina group, 13.1 ± 47.4 in NPDR group, and 9.9 ± 4.7 in PDR group (P < 0.001). LA conduit strain was 30.1 ± 6.6 in normal retina group, 25.3 ± 6.5 in NPDR group, and 22.9 ± 4.9 in PDR group (P < 0.001). Proportional odds regression for association between clinical data, echocardiographic parameters, and LA contractile strain function showed that increasing creatinine (from 0.7 to 1.0; OR 0.71; 95% CI 0.51-0.99; P = 0.04), DR presence (OR 0.24; 95% CI 0.11-0.50; P = 0.001), and increasing left atrial volume index (LAVI) (from 33.5 to 52.6; OR 0.62; 95% CI 0.43-0.89; P = 0.01) were associated with decreasing LA function; however, other variables indicated no association. CONCLUSIONS: Our results showed the relationship between LA deformation parameters and DR, although microvascular involvement is not a certainly defined cardiovascular risk factor. Further prospective studies are needed to determine the clinical importance of DR presence and its degree for deformation parameters.
RESUMEN
Background: We aimed to determine the clinical, echocardiographic and hemodynamic correlates of syncope as a presenting symptom in pulmonary embolism and its impact on in-hospital and long-term outcomes. Methods: Between July 2012 and October 2019, a total of 641 patients with PE (277 males, 364 females; median age: 65 years; range, 51 to 74 years) in whom the diagnostic work-up and risk-based management were performed according to the current pulmonary embolism guidelines were retrospectively analyzed. Clinical, laboratory and imaging data of the patients were obtained from hospital database system. Results: Syncope was noted in 193 (30.2%) of patients on admission, and was associated with a significantly higher-risk status manifested by elevated troponin and D-dimer levels, a higher Pulmonary Embolism Severity Index scores, deterioration of right-to-left ventricular diameter ratio, right ventricular longitudinal contraction measures, the higher Qanadli score, and higher rates of thrombolytic therapies (p<0.001) and rheolytic-thrombectomy (p=0.037) therapies. In-hospital mortality (p=0.007) and minor bleeding (p<0.001) were significantly higher in syncope subgroup. Multivariate logistic regression analysis showed that higher Pulmonary Embolism Severity Index scores and right-to-left ventricular diameter ratio were independently associated with syncope, while aging and increased heart rate predicted in-hospital mortality. Malignancy and right-to-left ventricular diameter ratio at discharge, but not syncope, were independent predictors of cumulative mortality during follow-up. Conclusion: Syncope as the presenting symptom is associated with a higher risk due to more severe obstructive pressure load and right ventricular dysfunction requiring more proactive strategies in patients with pulmonary embolism. However, with appropriate risk-based therapies, neither in-hospital mortality nor long-term mortality can be predicted by syncope.
RESUMEN
Background: Acute coronary syndrome (ACS) remains a major cause of morbidity and mortality worldwide. Although obesity is a risk factor for ACS, decreased mortality has been shown in overweight individuals. This study aims to determine the association of body fat parameters such as body fat percentage (BFP), relative fat mass (RFM), and coronary thrombus burden with angiographic thrombotic grade in a series of patients presenting with ACS. Methods: Three hundred ninety patients who underwent percutaneous coronary intervention were enrolled in the study. BFP was calculated using the U.S. Navy formula. RFM index was calculated using gender, height, and waist circumference regardless of weight. Body mass index (BMI) is calculated as the weight in kilograms divided by the square of body length in meters (kg/m2). Two experienced interventional cardiologists reviewed coronary angiograms according to the TIMI thrombus scale. Patients were divided into groups according to thrombus classification and clinical status. Results: RFM, which is an anthropometric measurement parameter for obesity, was inversely related to thrombus burden in patients with ACS. There were no significant differences between ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) groups according to demographic, clinical characteristics, and coronary risk factors. Likewise, RFM, BFP, and BMI were comparable between the two groups. BFP and RFM were lower in patients with thrombus present STEMI group compared with no thrombus group. Thrombus presence was also compared in the NSTEMI group, and BMI, BFP, and RFM were lower in patients with thrombus present NSTEMI group. Conclusions: Our analysis demonstrated that RFM was better than BFP and BMI for predicting thrombus presence in patients with ACS.
