RESUMEN

OBJECTIVE: Right ventricular (RV) overload findings affect the risk classification and treatment approach in acute pulmonary embolism (APE). Recently, it was reported that a new electrocardiography (ECG) parameter, terminal D1S + D3R (T-D1S + D3R) pattern, supported the diagnosis of APE. We aim to search the relationship between T-D1S + D3R pattern and right ventricular dilatation (RVD) in APE. METHODS: This single-centre, retrospective study was designed with patients aged > 18 years. We screened 267 patients who underwent transthoracic echocardiography (TTE) because of confirmed APE in our emergency department. This study included 72 patients with RVD and 139 patients without RVD [male 41.7%, median age 73,0 (20.8) years; 49.6% male, median age 64,0 (24.0) years]. We compared T-D1S + D3R between RVD (+) and RVD (-) groups. RESULTS: We determined that RVD (+) group had more patients with the T-D1S + D3R parameter than RVD (-) group [51 (70.8%) vs. 25 (18.0%), p < 0.001]. In the univariate logistic regression analyses S1Q3T3, (in)complete right bundle branch block (RBBB), T-D1S + D3R, D3-V1 T wave inversion (TWI), V1-3/4 TWI, V1-3/4 ST-segment elevation, and frontal QRS-T [f(QRS-T)] angle predicted RVD, while T-D1S + D3R, V1-3/4 ST-segment elevation, and f(QRS-T) angle remained independent predictors of RVD in patients with APE. CONCLUSIONS: T-D1S + D3R, a new ECG parameter, was an independent predictor of RVD in patients with APE.

RESUMEN

Heart failure (HF) is a clinical syndrome with various etiologies and presentations. The role of the inflammatory pathway in HF prognosis is not fully understood. We investigated the association between the systemic immune-inflammation index (SII) and HF complicated by right ventricular dysfunction (RVD) and whether the SII is related to compromised hemodynamic volume status. A total of 235 patients with HF with reduced ejection fraction (HFrEF) were enrolled and divided into 2 groups according to the presence of RVD. The relationship between the SII score, hemodynamic parameters, and clinical endpoints was evaluated. Higher SII scores and neutrophil counts (P < .001 and P = .017, respectively) were observed in the RVD group (n = 120). In the high SII score group (≥590.4), hospitalization and the need for positive inotrope treatment were significantly higher (P = .026 and P = .009, respectively), and left ventricular ejection fraction (LVEF) was significantly lower (P = .015). In addition, in the high SII score group, right heart catheterization values, including cardiac output and index, were significantly impaired compared with those in the lower SII score group. There was a significant negative correlation between the SII score and the LVEF, cardiac output, and cardiac index in the correlation analyses. A significant relationship was observed between indirect inflammation and RVD in patients with HFrEF. The hemodynamic volume status and functional capacity were impaired in patients with high SII scores. These results indicated that advanced HF with worse outcomes may be related to the inflammatory process.

RESUMEN

In patients with severe aortic stenosis, the data about the incidence of acquired thrombocytopenia according to the use of balloon-expandable or self-expandable valves are limited. We investigated the relationship between the post-transcatheter aortic valve replacement (TAVR) thrombocytopenia and the balloon-expandable or self-expandable valves. A total of 127 consecutive patients who underwent TAVR were retrospectively analyzed. Among the study population, 61 (48%) patients underwent TAVR with the balloon-expandable valve and the 66 (52%) patients with the self-expandable valve. Procedural success did not differ between the groups (P = .575). The access site complications and in-hospital mortality were the same across the groups (P = .225 and P = .466). However, paravalvular (PV) leaks were significantly higher in the self-expandable valve group (P = .007). Among all, 65 patients experienced thrombocytopenia, which was more frequent in the self-expandable valve group (63.6 vs 37.7%, P = .005). In multivariate analyses, admission platelet count, PV leak, and self-expandable valve deployment were the predictors of thrombocytopenia (P = .001, P = .002, and P = .021, respectively). The present study showed a higher incidence of acquired thrombocytopenia in the self-expandable valve group. Although the procedural success was similar between the groups, postprocedural PV leaks were more common in the self-expandable valve group.

RESUMEN

Coronary artery aneurysms are rare findings in patients referred for coronary angiography. Their prevalence ranges between 0.2% and 6% in different case series. We describe a male patient with a huge left main coronary artery aneurysm causing exertional angina, which was diagnosed with coronary angiography. All of the left coronary system arose from the aneurysm. He underwent coronary angiography again, followed by multislice computed tomography with a three-dimensional reconstruction. Although there is no known standard treatment modality for such aneurysms, we planned medical therapy after consultation with the cardiovascular surgery department. The patient's first visit was in March 2013, and he was thereafter followed up until September 2016.

RESUMEN

BACKGROUND: Although tremendous advances have been made in preventative and therapeutic approaches in heart failure (HF), the hospitalisation and mortality rates for patients with HF is high. The aim of this study was to investigate the association between cystatin C and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels and in- and out-of-hospital mortality rates in acute decompensated HF (ADHF). METHODS: Between February 2008 and November 2011, 57 consecutive patients who were admitted with ADHF were included in this prospective study. These patients were clinically followed up every three months by means of visits or telephone interviews. The primary clinical endpoint of this study was any death from heart failure rehospitalisation and/or other causes. RESULTS: The subjects who died during the in-hospital follow up were younger than the survivors (47.4 ± 17.5 vs 60.8 ± 15.8, p = 0.043). There was a notable correlation between plasma cystatin C and NT-proBNP levels (r = 0.324, p = 0.014) and glomerular filtration rate (GFR) (r = -0.638, p < 0.001). Multivariate logistic regression analysis revealed that only cystatin C level [odds ratio (OR): 12.311, 95% confidence interval (CI): 1.616-93.764, p = 0.015] and age [OR: 0.925, 95% CI: 0.866-0.990, p = 0.023] were linked to in-hospital mortality rate. In the multivariate Cox proportional hazard model, only admission sodium level appeared as a significant independent predictor of death during the 36-month follow up [hazard ratio: 0.937, 95% CI: 0.880-0.996, p = 0.037]. CONCLUSION: Evaluation of admission cystatin C levels may provide a reliable prediction of in-hospital mortality, compared to estimated GFR or NT-proBNP levels among patients with ADHF. However, in this trial, during long-term follow up, only admission sodium level significantly predicted death.

RESUMEN

BACKGROUND AND AIM: In patients diagnosed with coronary artery disease (CAD), we aimed to determine the characteristics and risk factors of co-occurring musculoskeletal pain and examine its effects on functional capacity, psychological status and health-related quality of life. PATIENTS AND METHODS: A total of 100 patients with (n= 50) and without (n= 50) musculoskeletal pain were enrolled. All patients were assessed on sociodemographic and clinical properties. The Duke Activity Status Index (DASI), the Hospital Anxiety and Depression Scale (HADS) and the Short Form-36 (SF-36) were applied as clinical assessment scales. RESULTS: Patients with musculoskeletal pain were mostly female, and had a lower education level and annual income. The pain was mostly nociceptive, intermittent, sharp/stabbing in character, and located in the chest and spine. Having musculoskeletal pain resulted in lower levels on the DASI and all subgroups of the SF-36, and higher levels on the HADS. Female gender, lower education level and severity of emotional distress proved to be independent risk factors for the development of musculoskeletal pain. CONCLUSIONS: In CAD, the co-occurrence of musculoskeletal pain leads to a further decrease in health-related quality of life and functional status, and increased severity of anxiety and depression. This stresses the importance of the detection and optimal treatment of musculoskeletal pain in patients diagnosed with CAD.

RESUMEN

BACKGROUND: We aimed to investigate the accuracy of four algorithms in prediction of right ventricular outflow tract (RVOT) tachycardias in patients who successfully underwent radiofrequency catheter ablation. METHODS: Four algorithms; two with easy-applicability and having a memorable design (Dixit and Joshi), and two with more complex and detailed design (Ito and Zhang) were compared according to the predictive accuracy. RESULTS: Among 99 patients (mean age 36.5 ± 8.5 years, 39.4% male), there were 51 (51.5%) septal-located and 48 (48.5%) free-wall located RVOT tachycardia. Comparison of the predictive accuracy of the algorithms showed that Zhang (91.9%) was the best algorithm for prediction of either septal or free-wall located tachycardia. The second best algorithm was the Ito (77.7%) compared to Dixit (75.8%) and Joshi (70.7%). CONCLUSION: In patients with RVOT tachycardia, algorithms with a detailed design may predict the arrhythmia location better than the easy-applicable algorithms.

RESUMEN

We evaluated the efficacy and safety of the fixed dose of 5000 IU unfractionated heparin (UFH) represented as peak activated clotting time (ACT) according to the body mass index (BMI) tertiles in patients undergoing diagnostic transradial coronary angiography (TRCA). A total of 422 patients were included in the present study, 84 in the normal weight group, 218 in the overweight group, and the 120 in the grades 1 and 2 obesity groups. Radial artery occlusion (RAO) was observed in 29 (6.8%) patients and the hematoma was observed in 43 (10.1%) patients. The rate of RAO and hematoma did not differ across the BMI tertiles ( P = .749 and P = .066). Also, peak ACT and procedure duration did not differ between the study groups ( P = .703 and P = .999). The only independent predictor of hematoma was sheath/radial artery diameter ( P = .011) and the independent predictors for RAO were peak ACT, sheath/radial artery diameter, and procedure duration ( P = .001, P = .028, and P < .001, respectively). In conclusion, a fixed dose of 5000 IU UFH is safe and effective regardless of the BMI in diagnostic TRCA procedure.

RESUMEN

OBJECTIVE: Transradial access is widely used for both diagnostic and interventional cardiac procedures. The use of transradial access offers several advantages, including decreased bleeding, fewer vascular complications, and reduced length of hospital stay and cost. However, the small size of the radial artery limits the size of the equipment that can be used via this approach. In this study we sought to investigate whether preprocedural manual heating of the radial artery facilitates radial artery puncture. METHODS: Patients undergoing transradial cardiac catheterization were randomized to subcutaneous nitroglycerin plus diltiazem or manual heating. The study endpoint was puncture score (score 1: easiest - puncture at first attempt; score 2: second attempt; score 3: third attempt; score 4: fourth attempt or more; score 5: puncture failed). RESULTS: Ninety consecutive patients were enrolled in the study, 45 allocated to the drug treatment group and 45 to the heating group. Patients underwent radial artery ultrasound before catheterization. Complications were rare: one hematoma (drug treatment group) and one radial artery occlusion (heating group). Baseline demographic and clinical characteristics were similar. Baseline radial artery diameter was similar in both groups (2.41±0.46 mm and 2.29±0.48 mm in the heating and drug treatment groups, respectively). However, the median puncture score was lower in the heating group (1; interquartile range 1-2) compared to the drug treatment group (2; interquartile range 1-3; p=0.001). CONCLUSIONS: Preprocedural manual heating of the radial artery facilitates radial artery puncture in patients undergoing transradial cardiac catheterization.

RESUMEN

OBJECTIVE: Despite recent advances in medical support and interventions, only 5% to 10% of patients with out-of-hospital cardiac arrest (OHCA) survive to discharge. In this study, factors related to neurologically favorable survival in patients with OHCA were analyzed. METHODS: A total of 129 patients who were admitted to hospital with OHCA were retrospectively enrolled. RESULTS: Sustained return of spontaneous circulation (ROSC) (ROSC lasting >20 min) was achieved in 29 (22.4%) patients. Percentage of cardiac arrests with ischemic etiology was significantly higher in successful ROSC group (p<0.001). In multivariate logistic regression analysis, cardiac arrest with ischemic etiology (p=0.004) and cardiopulmonary resuscitation (CPR) duration (p=0.013) were found to be independent predictors for ROSC. One-minute increment in CPR duration was associated with 1.202-fold increase in failure to achieve ROSC. Among patients with ROSC, 7 (5.4%) survived to hospital discharge, and 1-minute increment in CPR duration was associated with a 1.123-fold decrease in neurologically favorable survival (p=0.005). CONCLUSION: In patients with OHCA, ischemic etiology is associated with better ROSC rate compared to other reasons for cardiac arrest, and patients with prolonged CPR are less likely to survive.
