Background: Mitral annular flutter (MAF) is the most common left atrial macro‐reentrant arrhythmia following catheter ablation of atrial fibrillation (AF). The best ablation approach for this arrhythmia remains unclear. Methods: This single‐center, retrospective study sought to compare the acute and long‐term outcomes of patients with MAF treated with an anterior mitral line (AML) versus a mitral isthmus line (MIL). Acute ablation success, complication rates, and long‐term arrhythmia recurrence were compared between the two groups. Results: Between 2015 and 2021, a total of 81 patients underwent ablation of MAF (58 with an AML and 23 with a MIL). Acute procedural success defined as bidirectional block was achieved in 88% of the AML and 91% of the MIL patients respectively (p = 1.0). One year freedom from atrial arrhythmias was 49.5% versus 77.5% and at 4 years was 24% versus 59.6% for AML versus MIL, respectively (hazard ratio [HR]: 0.38, confidence interval [CI]: 0.17–0.82, p =.009). Fewer patients in the MIL group had recurrent atrial flutter when compared to the AML group (HR: 0.32, CI: 0.12–0.83, p =.009). The incidence of recurrent AF, on the other side, was not different between both groups (21.7% vs. 18.9%; p =.76). There were no serious adverse events in either group. Conclusion: In this retrospective study of patients with MAF, a MIL compared to AML was associated with a long‐term reduction in recurrent atrial arrhythmias driven by a reduction in macroreentrant atrial flutters.

- Abstract
Interatrial block (IAB) is defined as prolonged P-wave duration (≥ 120 ms) due to delayed conduction in the Bachmann bundle. This is readily identifiable using surface electrocardiogram (ECG). Advanced IAB can be classified as typical and atypical. Atypical IAB can be further categorized by (i) duration or (ii) morphology. In this report, we have identified a new pattern of atypical IAB with triphasic morphology of the P-wave in the inferior leads. Two clinical cases were evaluated including surface ECGs. P-wave durations and amplitudes were measured with digital calipers using ECG analysis software (MUSE, GE HealthCare). Comparisons were made using prior data to evaluate IAB and P-wave duration and morphology. A new pattern of atypical advanced IAB shows prolonged P-wave duration (P wave >160 ms) and triphasic morphology in all inferior leads with P +/+/− and P +/−/+, respectively. We speculate that triphasic P-waves in the inferior leads represent three moments of atrial depolarization; from right to left. This study describes a novel pattern of atypical advanced IAB. Further investigation regarding the increased risk of atrial fibrillation and stroke associated with this new pattern is warranted in the future. [ABSTRACT FROM AUTHOR]

Ramadan interferes with circadian rhythms mainly by disturbing the routine patterns of feeding and smoking. The objective of this study was to investigate the circadian pattern of ST elevation acute myocardial infarction (STEMI) during the month of Ramadan. We studied consecutive STEMI patients 1 month before and after Ramadan (non-Ramadan group-NRG) and during Ramadan (Ramadan group-RG). The RG group was also divided into two groups, based on whether they chose to fast: fasting (FG) and non-fasting group (NFG). The time of STEMI onset was compared. A total of 742 consecutive STEMI patients were classified into 4 groups by 6 h intervals according to time-of-day at symptom onset. No consistent circadian variation in the onset of STEMI was observed both between the RG (P =.938) and NRG (P =.766) or between the FG (P =.232) and NFG (P =.523). When analyzed for subgroups of the study sample, neither smoking nor diabetes showed circadian rhythm. There was a trend towards a delay from symptom onset to hospital presentation, particularly at evening hours in the RG compared with the control group. In conclusion, there was no significant difference in STEMI onset time, but the time from symptom onset to hospital admission was significantly delayed during Ramadan. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Peripheral artery disease (PAD) is part of the systemic atherosclerotic process that is highly associated with cardiovascular diseases. Despite successful endovascular treatment (EVT) strategies, mortality and morbidity rates still remain higher in PAD patients. C-reactive protein (CRP) and albumin are biomarkers of inflammation and malnutrition that play key roles in the progression of peripheral arterial disease. In this study, we aimed to investigate the relationship between CRP-to-albumin ratio (CAR) and mortality and amputation-free survival in patients with PAD after successful EVT. Method: Our study enrolled 149 consecutive patients who underwent EVT on atherosclerotic obstruction of iliac, femoral, popliteal and/or below-knee arteries with the clinical features of PAD and/or chronic limb-threatening ischaemia between January 2015 and January 2020. Clinical and prognostic follow-up of patients had been done at the outpatient clinic and were collected from institution's medical records. Results: The mean follow-up period was 22 months (14–40). All-cause mortality and amputation rates of patients in the high CAR group were significantly higher than those in the low CAR group (21.3% vs. 6.8% and 18.7% vs. 5.4%, respectively). Kaplan–Meier survival analysis showed significantly better survival for patients in the low CAR group (log-rank p = 0.0058). In multivariate logistic regression analysis, CAR was found to be an independent predictor of amputation and all-cause mortality even after adjusting for other confounding risk factors. ROC curve analysis revealed the optimal cut-off value of CAR for predicting all-cause mortality and amputation to be >1.476 with a sensitivity of 48.5% and specificity of 94.0%. Conclusion: The inflammatory state reflected by CAR levels was strongly associated with all-cause mortality and amputation after EVT in patients with PAD. Furthermore, CAR was found to be an independent predictor of these clinical outcomes after adjusting for other clinically associated parameters. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Congenital myopathies (CMs) are a group of rare genetic muscle disorders. Cardiac involvement can be seen in these patients. We aimed to evaluate the myocardial strain parameters by 2D speckle-tracking echocardiography (STE) in patients with CM. Materials and Methods: Twenty-four patients with CM whose diagnosis was confirmed by genetic analysis or muscle biopsy were included in the study, and 48 patients were involved as a control group. Left ventricular ejection fraction (LVEF%) was calculated by biplane Simpson method, and myocardial strain analysis was performed by 2D STE. Results: The median age of the study population was 26 (19–35 interquartile range [IQR]) and 43 (60%) were women. In the analysis performed after the exclusion of two patients with multiminicore disease (MMD) who developed heart failure, although mild, LVEF% (62 [60–65 IQR] vs. 64 [63–66 IQR], P = 0.008) and right ventricular global longitudinal strain (RVGLS) were significantly lower in the CM group (−21.8 [−19.7, −24.9 IQR] vs. −23.9 [−22.4, −25.6 IQR], P = 0.0017). Left ventricular global longitudinal strain (LVGLS) was observed similarly in both groups (−19.9 [−18.7, −20.7 IQR] vs. −20.5 [−19.3, −21.9 IQR], P = 0.069). LVEF% (33 and 46), LVGLS (−7.5 and −10.7), and RVGLS (−14.9 and −16.1) values were low in two siblings with MMD. Conclusion: Although LVEF% and RVGLS were significantly lower in the CM group, LVGLS was similar. The decrease in RVGLS and LVEF% was mild, and heart failure was not observed in any patient except MMD patients who were not included in the analysis. [ABSTRACT FROM AUTHOR]

Aim: The number of diagnostic coronary angiography is increasing. Although previously thought that non-obstructive coronary artery disease (CAD) does not cause an increase in mortality risk, there is recently evidence that it increases mortality. In this study, we aimed to determine the mortality rates and possible predictors of all-cause death in long-term follow-up of patients who underwent coronary angiography (CAG) due to stable angina and whose SYNTAX score was zero including normal coronary arteries, minimal CAD or non-obstructive CAD, coronary slow flow, coronary artery aneurysms and ectasia. Materials and Methods: This study included 1489 patients who underwent CAG due to stable angina pectoris. In-hospital and post-discharge follow-up data were obtained. Patients' CAG images were evaluated and SYNTAX scores were calculated using the website calculator. Results: Among the 1489 patients, 64 (4.3%) all-cause deaths were observed during the 19 ± 1.1 months of follow up period. Although, no significant difference was observed between the 2 groups in terms of the presence of plaque in coronary arteries with a vessel diameter of ≤ 1.5 mm, the rate of patients with plaque in coronary arteries with a diameter of > 1.5 mm was significantly higher in the group of patients who died compared to the patients living (48 (75%) vs 842 (% 59.1), p = 0.011). The cumulative survival curve of the patients was obtained and in patients with coronary plaque in any of the coronary arteries with a vessel diameter of > 1.5 mm was significantly associated with worse survival. Conclusion: There was increase in all-cause mortality in patients who underwent CAG due to stable angina and who have at least one non-obstructive lesion in the coronary arteries > 1.5 mm. Therefore, appropriate risk classification, life style changes and appropriate medical follow-up may be important in these patients. [ABSTRACT FROM AUTHOR]

Introduction: This study aimed to evaluate the predictive role of the Geriatric Nutrition Risk Index in long-term mortality of very elderly patients with ST-segment elevation myocardial infarction and to compare it with the other known objective nutritional indices, namely the Prognostic Nutritional Index and Controlling Nutritional Status. Materials and Methods: A total of 212 eligible patients, aged 80 years or older, who were hospitalized with a diagnosis of ST-segment elevation myocardial infarction and underwent primary percutaneous coronary intervention were included in the study. Baseline patient characteristics, echocardiographic assessments, laboratory findings, and nutritional indices were assessed. Results: During the median follow-up period of 34 months, 60 (28.3%) allcause mortalities were identified, and event-free cumulative rates were 46.3%, 81.4%, and 90.1% for Geriatric Nutrition Risk Index <100.5, 100.5-112.6, and >112.6, respectively (log-rank test, p < 0.0001). Receiver operating characteristic curve comparison analysis revealed that the Geriatric Nutrition Risk Index was a better predictor than the Controlling Nutritional Status, Prognostic Nutritional Index, Body Mass Index, and serum albumin (p < 0.001 for each pairwise comparison of Receiver operating characteristic curves). Conclusion: It is important to evaluate malnutrition that is known to be associated with mortality in very elderly patients with ST-segment elevation myocardial infarction, who are more fragile than young people, and Geriatric Nutrition Risk Index -a simple and easy-to-calculate index-can be a guide in this regard.

- Abstract
Background: Peripheral arterial disease is associated with increased cardiovascular mortality and morbidity. C-reactive protein and albumin are biomarkers of inflammation and malnutrition that play key roles in the pathophysiological pathways involved in the progression of atherosclerosis and peripheral arterial disease. In this study, we aimed to assess the relationship between C-reactive protein to albumin ratio and the suprapopliteal peripheral arterial disease severity and complexity as assessed by TransAtlantic Inter-Society Consensus-II (TASC-II) classification. Method: Our study enrolled 224 consecutive patients referred for peripheral angiography with the clinical features of possible peripheral arterial disease at a tertiary care center between January 2016 and September 2019. Level of disease and lesion characteristics were defined with reference to angiographic findings according to the TASC-II classification. Results: C-reactive protein/albumin ratio levels were significantly higher in TASC-II class C and D than in TASC-II class B patients with a median level of 1.8 to 2.1 vs 1.4, respectively (p = 0.018). In multivariate regression analysis, C-reactive protein to albumin ratio remained an independent predictor of severe peripheral arterial disease. The predictive performance of C-reactive protein to albumin ratio, C-reactive protein, and albumin were compared by Receiver Operating Characteristic curve analysis. C-reactive protein to albumin ratio surpassed C-reactive protein and albumin in predicting peripheral arterial disease severity and complexity. A level of C-reactive protein to albumin ratio > 0.14 predicted a higher grade of suprapopliteal TASC-II class with sensitivity and specificity of 68.2% and 56.0%, respectively. Conclusion: C-reactive protein to albumin ratio was strongly associated with peripheral arterial disease severity and complexity, as assessed by TASC-II classification. Also, C-reactive protein to albumin ratio was found to be a more accurate marker than C-reactive protein and albumin alone in predicting more severe and complex lesions in patients with peripheral arterial disease.

Objective: Acute kidney injury (AKI), which is prevalent in ST-segment elevated myocardial infarction (STEMI) patients who have undergone primary percutaneous coronary intervention (PCI), is associated with poor cardiovascular outcomes. As high pulse pressure (PP) is associated with adverse cardiovascular events, the present study's aim was to evaluate the relationship between fractional PP (PPf) and AKI in patients with STEMI who underwent primary PCI.Subjects and Methods: All laboratory findings as well as echocardiographic and angiographic data of 1,170 consecutive STEMI patients were retrospectively screened. PPf was calculated from the pressures invasively measured after sheath insertion and before performing coronary angiography.Results: From 1,170 eligible STEMI patients (mean age 56 years, 18.2% female), AKI developed in 143 (12.2%) patients. The PPf and pulsatility index were significantly higher in patients with AKI than those without (0.53 ± 0.10 vs. 0.61 ± 0.10, p < 0.001, and 0.80 ± 0.03 vs. 0.82 ± 0.03, p < 0.001, respectively). PPf was also found to be associated with AKI in univariable (OR 2.183, 95% CI 1.823-2.614, p< 0.001) and multivariable (OR 1.874, 95% CI 1.513-2.322, p < 0.001) analysis. In-hospital mortality was higher in patients with AKI than those without.Conclusion: Invasively measured PPf, which can be easily measured and has no additional cost in STEMI patients undergoing coronary intervention, is an independent predictor of AKI. In addition, PPf is superior to other blood pressure values and derivatives in AKI prediction. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background: The effect of favipiravir on the QTc interval during the treatment of Coronavirus Disease 2019 (COVID-19) patients is unclear. Thus, the current study objective was to evaluate any change in the QTc interval in patients who were hospitalized due to COVID-19 receiving favipiravir treatment.Method: Patients hospitalized with COVID-19 were assessed in this single-center retrospective study. 189 patients, whose diagnosis was confirmed using real-time PCR, were included in the study. The patients were divided into three groups: those using hydroxychloroquine (Group 1, n = 66), hydroxychloroquine plus favipiravir (Group 2, n = 66), and favipiravir only (Group 3, n = 57). The QTc interval was measured before treatment (QTc-B) and 48 h after (i.e., the median) starting treatment (QTc-AT).Results: The median age was 53 (39-66 IQR) and 97 (51%) of patients were female. The median QTc(Bazett)-change was 7 ms (p = 0.028) and 12 ms (p < 0.001) and in Group 1 and 2, respectively. In Group 3, the median QTc(Bazett)-change was observed as -3 ms and was not statistically significant (p = 0.247). In multivariable analysis, while there was a significant relationship between QTc-AT(Bazett) and hydroxychloroquine (β coefficient = 2687, 95%CI 2599-16,976, p = 0,008), there was no significant relationship with favipiravir (β coefficient = 0,180, 95% CI -6435-7724, p = 0,858). Similarly, there was a significant relationship between the QTc-AT interval calculated using the Fredericia formula and hydroxychloroquine (β coefficient = 2120, 95% CI 0,514-14,398, p = 0,035), but not with favipiravir (β coefficient = 0,111, 95% CI -6450- 7221, p = 0,911).Conclusion: In the ECG recordings received in the following days after the treatment was started in COVID-19 patients, there was a significant prolongation in the QTc interval with hydroxychloroquine, but there was no significant change with favipiravir.

- Abstract
Objective: Many studies have examined the capability of electrocardiography (ECG) changes to predict the severity and prognosis of patients with acute pulmonary embolism (APE). RS time in ECG is potentially valuable in evaluating the prognosis of APE. In our study, we aimed to assess the predictive value of RS time, which is a novel electrocardiographic parameter of one-month mortality of APE.Methods: This retrospective study included 216 patients who were diagnosed with APE by pulmonary computed tomography angiography. RS time was measured from the ECG (inferolateral leads) at the time of hospital admission using a computer program (imagej.nih.gov/ij/). The patients were divided into two groups according to the median values of RS time: the group with RS time ≤ 60 msec (n:108) and the group with RS time > 60 msec (n:108). The groups were compared in terms of mortality.Results: In our study, the one-month mortality was 15.3% (33) in the patients hospitalized with APE. In the multivariate analysis, RS time prolongation (HR: 1.037; 95%CI: 1.005-1.065; p = .02) was independently correlated with mortality. The ROC curve analysis revealed that RS time > 64.8 msec predicted the one-month mortality in APE with a sensitivity of 68.6% and a specificity of 73.9% (AUC: 0.708; 95% CI: 0.643-0.768; p < .001).Conclusion: As a novel ECG parameter, RS time could be measured for each patient with APE. Prolongation of RS time could be a useful index for predicting the one-month mortality of patients diagnosed with APE. [ABSTRACT FROM AUTHOR]- Published

Background: Different arterial segments throughout the vascular system develop similar grades of atherosclerosis concomitantly. Urethral ischemia has been proposed as a cause of urethral stricture. Therefore, we aimed to investigate the relationship between coronary artery disease severity using a SYNTAX score and urethral stricture occurrence after urethral catheterization in patients with non--ST-segment-elevation acute coronary syndrome (ACS). Methods: This retrospective study consisted of 306 men with urethral catheters that were diagnosed with ACS and underwent coronary angiography between January 2016 and January 2018 in Kars Kafkas University and Osmaniye Government Hospital, Turkey. Hospital records were reviewed to collect the follow-up data of the patients regarding the occurrence of urethral stricture after urethral catheterization. The study population was divided into 2 groups according to urethral stricture development, and both groups were compared statistically. Results: SYNTAX scores were significantly higher in patients with urethral stricture than in those without urethral stricture (14.86±7.11 vs. 29.25±9.79; P<0.001). The SYNTAX score (OR=1.27; 95% CI: 1.16-1.39; P<0.001), diabetes, and serum albumin were found to be the independent predictors of urethral stricture. The receiver operating characteristic curve analysis showed that the cutoff value of the SYNTAX score for urethral stricture prediction was greater than 22.5, with 76.7% sensitivity and 85.1% specificity (AUC=0.88, 95% CI: 0.84-0.91; P<0.001). Conclusion: Coronary artery disease severity graded according to the SYNTAX score is an independent predictor of urethral stricture occurrence in ACS patients with a urethral catheter inserted.

Introduction and objectives: The aim of this study was to investigate the association of serum albumin (SA) level with long‐term prognosis in patients with acute pulmonary embolism (PE). Materials and methods: We retrospectively enrolled 269 patients with acute PE. The SA level was obtained within 12‐24 hours following admission. The primary endpoints were the incidence of short‐ and long‐term mortality in acute PE patients. The mean duration of the study follow‐up was 21 ± 19 months. Results: During the follow‐up period, short‐ and long‐term mortality rates were higher in patients who had low SA level compared to those who did not have. In multivariate Cox regression analysis, the SA level was found to be independently associated with long‐term mortality (HR: 0.47, 95%CI: 0.28‐0.78, P = 0.004). In receiver operating characteristics analysis, the SA level of ≤3.17 predicted long‐term mortality with a sensitivity of 77.5% and a specificity of 79.5% (area under the curve 0.82, 95%CI: 0.76‐0.87, P < 0.001). In addition, when the SA plus simplified pulmonary embolism severity index (sPESI) risk score compared to the sPESI risk score alone, it produced a net reclassification improvement of 0.22 with P < 0.001, that is a 22% improved classification. Conclusion: To the best of our knowledge, this is the first study to demonstrate that the low SA level is a strong and independent predictor for long‐term mortality in patients with acute PE.

Objective: An increased left atrial volume index (LAVI) is related to increased mortality in hemodialysis patients. In the present study, we evaluated the association between the LAVI and the P wave peak time (PWPT), a newly introduced electrocardiographic parameter, in hemodialysis patients.Methods: The study population was made up of 79 hemodialysis patients with a mean age of 53 ± 18 years (55.7% were males). These patients were divided into a normal LAVI (≤28 mL/m2) group (n = 45) and an increased LAVI (>28 mL/m2) group (n = 34). The demographic, clinical, laboratory, echocardiographic, and electrocardiographic variables of the groups were compared.Results: The P wave terminal force from lead V1, P wave dispersion and PWPTs obtained from leads V1 and D2 (PWPTD2) were significantly higher in the patients with increased LAVIs. In multivariable analysis, only the PWPTD2was an independent predictor of an increased LAVI (odds ratio = 1.117, 95% CI = 1.052-1.185, p < 0.001). The receiver-operating characteristic curve analysis showed that the best PWPTD2 cutoff value for predicting an increased LAVI was 60 ms, with a sensitivity of 76.5% and a specificity of 66.7% (area under the curve = 0.736, 95% CI = 0.625-0.829, p < 0.001).Conclusion: This study showed that a prolonged PWPTD2 was independently associated with an increased LAVI in hemodialysis patients. Therefore, measuring the PWPTD2 duration on an electrocardiogram may help define high-risk hemodialysis patients with increased LAVIs. [ABSTRACT FROM AUTHOR]- Published

Contrast-induced nephropathy (CIN) is a prevalent and serious complication after primary percutaneous coronary intervention (pPCI). Although the association between serum osmolarity and chronic kidney disease is well established, its relation to CIN in patients with ST-segment elevation myocardial infarction (STEMI) undergoing pPCI needs to be elucidated. We evaluated the predictive value of serum osmolarity for CIN development in patients with STEMI (n = 768) undergoing pPCI. Serum osmolarity on admission was calculated. The study population was divided into 2 groups according to CIN development, and both groups were compared according to clinical, laboratory, and demographic features, including the serum osmolarity. Serum osmolarity was significantly higher in patients with CIN than in those without CIN (278 [8] vs 284 [9]; P =.024). Serum osmolarity (odds ratio: 1.052; 95% confidence interval: 1.018-1.086; P =.002), hemoglobin, contrast media volume, creatinine on admission, basal SYNergy between PCI with TAXus and cardiac surgery II score, and left ventricular ejection fraction were found to be independent predictors of CIN. Serum osmolarity (given the simple calculation of this parameter on admission) can be useful to define patients with STEMI undergoing pPCI who are more likely to develop CIN. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Multi-vessel coronary artery disease (CAD) is associated with worse outcome in non-ST segment elevation myocardial infarction (NSTEMI) patients. Depending on the severity of CAD, there may be prolongation of atrial depolarization time as a result of left ventricular dysfunction and atrial ischemia. Therefore, we aimed to study whether the severity of CAD can be predicted with the P wave peak time (PWPT) in the electrocardiography (ECG) obtained during the diagnosis in NSTEMI patients.Method: A total of 162 patients were included. The coronary angiography records of all patients were analyzed and SYNTAX scores were calculated. Patients were divided into two groups, according to CAD severity. In addition to well-known P wave parameters, PWPT, defined as the time from the beginning of the P wave to its peak, was measured in the leads DII and V1.Results: The PWPTs in the leads DII and V1 were significantly longer in the group with severe CAD (71 ± 13 vs. 61 ± 12, p < 0.001, 63 ± 24 vs. 53 ± 18, p = 0.024, respectively). PWPT was found to be an independent predictor of severe CAD and the best cut-off value of PWPT in the lead DII was 69.6 ms with sensitivity of 58.3% and specificity of 78.9%.Conclusion: Our findings show that prolonged PWPT, which is a parameter easily obtainable from the ECG, is associated with severe CAD. Recognition of NSTEMI patients with severe CAD at the time of diagnosis before performing coronary angiography may be important for the planning of treatment. [ABSTRACT FROM AUTHOR]- Published

Introduction: The present study aimed to evaluate the potential utility of thrombosis in myocardial infarction (TIMI) risk index (TRI) for the prediction of stent thrombosis (ST) in ST elevation myocardial infarction (STEMI) patients who were treated with primary percutaneous coronary intervention (pPCI). Methods: This retrospective study was related to the clinical data of 1275 consecutive STEMI patients who underwent pPCI from January 2013 to January 2018. The TRI was calculated for each patient, and the following equation was used; TRI = heart rate x [age/10]2/systolic blood pressure. For the definition of ST, the criteria as proposed by the Academic Research Consortium were applied. Results: The incidence of ST was 3.2% (n=42 patients) in the study. The median value of the TRI was significantly elevated in patients with ST compared to those without ST (22 [17-32] vs. 16 [11-21], P <0.001, respectively). In a multivariate logistic regression analysis, the TRI was an independent predictor of ST (odds ratio [OR]: 1.061; 95% CI: 1.038-1.085; P <0.001). In a receiver operating characteristic curve analysis, the optimal value of the TRI for the prediction of ST was 25.8 with a sensitivity of 45.2% and a specificity of 86.4%. Conclusion: The present study finding has demonstrated that the TRI may be an independent predictor of ST in STEMI patients who were treated with pPCI. To the best of our knowledge, this is the first study in the literature in which the TRI and its relationship with ST was evaluated in STEMI patients treated with pPCI. [ABSTRACT FROM AUTHOR]

- Abstract
Left ventricular diastolic dysfunction (LVDD) is commonly seen in hypertensive patients, and it is associated with increased morbidity and mortality. Hence, the detection of LVDD with a simple, inexpensive, and easy-to-obtain method can contribute to improving patient prognosis. Therefore, we aimed to evaluate whether there was any association between the electrocardiographic P wave peak time (PWPT) and invasively measured left ventricular end-diastolic pressure (LVEDP) in hypertensive patients who had undergone coronary angiography following preliminary diagnosis of coronary artery disease. A total of 78 patients were included in this cross-sectional study. The PWPT was defined as the time from the beginning of the P wave to its peak, and it was calculated from the leads DII and VI . In all patients, LVEDP was measured in steady state. The PWPT in lead DII was significantly longer in patients with high LVEDP; however, there was no significant difference between groups in terms of PWPT in the lead VI . In multivariable analysis, PWPT in lead DII was found to be independent predictor of increased LVEDP (OR: 1.257, 95% CI: 1.094-1.445; P = 0.001). In receiver operating characteristic curve analysis, the optimal cut-off value of PWPT in the lead DII for prediction of elevated LVEDP was 64.8 ms, with a sensitivity of 68.7% and a specificity of 91.3% (area under curve: 0.882, 95% CI: 0.789-0.944, P < 0.001). In conclusion, this study result suggested that prolonged PWPT in the lead DII may be an independent predictor of increased LVEDP among hypertensive patients. [ABSTRACT FROM AUTHOR]

Background/aim: The number of patients with heart transplantation has dramatically increased in the last decade. Considerable studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarization and increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. We analyzed the dispersion of myocardial repolarization using electrocardiographic Tp-e interval and Tp-e/QTc ratio in patients with heart transplantation. Materials and methods: This observational study included 38 patients (12 female and 26 male) with heart transplantation and 38 wellmatched controls. From electrocardiograms, Tp-e interval and Tp-e/QTc ratio were calculated and compared between the 2 groups. Results: Noninvasive arrhythmia indicators including Tp-e interval (84.63 ± 14.17 ms vs 71.82 ± 7.47 ms, P < 0.001), Tp-e/QTc ratio (0.19 ± 0.04 vs 0.16 ± 0.02, P < 0.001) and QTc interval except QT interval were significantly higher in transplanted hearts compared to normal hearts. Conclusion: Patients with heart transplantation have increased myocardial dispersion of repolarization. [ABSTRACT FROM AUTHOR]

- Abstract
SYNTAX score II (SS-II) has a powerful prognostic accuracy in patients with stable complex coronary artery disease who have undergone revascularization; however, there is limited data regarding the prognosis of patients with ST segment elevation myocardial infarction (STEMI). The aim of this study is to examine both the predictive performance of SS-II in determining in-hospital and long term mortality of STEMI patients and to compare SYNTAX score (SS) and TIMI risk score (TRS). Consecutive 1912 STEMI patients treated with primary percutaneous coronary intervention (p-PCI) retrospectively reviewed, and the remaining 1708 patients constituted the study population after exclusion. The patients were divided into three groups according to increased SS-II value: low (n:562; SS-II ≤ 24.6); intermediate (n:563; 24.6 < SS-II < 34.4); and high tertile (n:583; SS-II ≥ 34.4). In-hospital and long term mortality rate from all causes (0 vs. 0.5 vs. 10.6% and 1.8 vs. 3.2 vs. 18.1% respectively, p ≤ 0.001) were significantly increased with SS-II tertiles and SS-II was found to be independent predictor of in-hospital and long term mortality (HR: 1.076 95% CI 1.060-1.092, p < 0.001) and (HR: 1.070 95% CI 1.050-1.090, p < 0.0001). The predictive power of SS-II, SS, and TRS were compared by ROC curve and decision curve analysis. SS-II surpassed SS and TRS in long-term and in-hospital mortality prediction. SS-II is a powerful tool to predict in-hospital and long-term mortality from all causes in STEMI patients treated with p-PCI. [ABSTRACT FROM AUTHOR]

Abstract: Background: The ratio of serum C‐reactive protein (CRP) to albumin has been proven to be a more accurate indicator than albumin and CRP levels alone in determining the prognosis of patients with cancer and critical illness. The aim of this study was to determine whether the CRP/albumin ratio (CAR) can be linked to imperfect reperfusion that can worsen the prognosis of ST‐elevation myocardial infarction (STEMI) in patients treated with primary percutaneous coronary intervention (pPCI). Materials and methods: A total of 1217 consecutive STEMI patients who achieved epicardial vessel patency with pPCI were recruited to this study. Results: The study population was divided into 2 groups: reflow (n = 874) and no‐reflow (NR) (n = 343) groups. The white blood cell count (WBC), neutrophil‐to‐lymphocyte ratio (NLR) and CAR (0.03 [0.01‐0.04] vs 0.06 [0.03‐0.12] (P < .001) were significantly higher in the NR group than in the reflow group, and these factors were found to be independent predictors of NR development. The best cut‐off value of CAR predicting NR was 0.59 with a sensitivity of 54.7% and specificity of 86.7. The predictive power of CAR surpassed that of CRP, albumin, WBC count and NLR in the receiver operator curve (ROC) curve comparison. Conclusion: No‐reflow can be predicted by systemic inflammation markers including WBC count, NLR and CAR measured from the blood sample obtained on admission. CAR has a higher clinical value than CRP, albumin level, WBC count and NLR in NR prediction. [ABSTRACT FROM AUTHOR]

- Abstract
High altitudes can cause hypobaric hypoxia, altering human physiology and the corresponding electrocardiogram (ECG). As part of the Altitude Nondifferentiated ECG Study (ANDES), this paper reviews ECG changes in subjects ascending to high altitudes. This review was conducted following PRISMA guidelines. PubMed, EMBASE, OVID Medline, and Web of Science were searched. 19 studies were ultimately included. Notable ECG changes at high altitudes include T wave inversion in the precordial leads and rightward QRS axis deviation in leads I, II and aVF. Less common findings were increases in P wave amplitude, QRS amplitude, and QTc interval. These ECG deviations typically self-resolved within 2-6 weeks following return to sea level. Consideration must be taken when interpreting ECG changes in individuals during ascent to, at, or upon return from high altitudes. Further large-scale studies are needed to elucidate temporal and altitude-dependent ECG patterns and establish reference standards for clinicians. Summary of physiological and ECG findings for human subjects ascending and acclimatizing to high altitudes with low levels of atmospheric oxygen. Created with BioRender.com.

- Abstract
Entrainment is an important tool for the diagnosis and location of reentry. The usefulness of this maneuver requires that, prior to cessation of ventricular pacing, the atrial rate accelerates to the ventricular pacing rate. Moreover, it is important to verify the continuation of the tachycardia following cessation of entrainment. The recognizing the last entrained atrial beat is utmost important to avoid erroneous A–A–V labeling. [ABSTRACT FROM AUTHOR]

Background: Rheumatic heart disease (RHD) is a serious health concern in developing countries. Rheumatic mitral stenosis (RMS) is the most long-term sequel in RHD. The neutrophil to lymphocyte ratio (NLR) is a novel marker, and a higher NLR has been associated with poor clinical outcomes in various cardiovascular disorders. We evaluated the availability of NLR to predict severity of mitral stenosis (MS) in patients with RHD. Methods: We analyzed 300 consecutive patients with RMS. The patients were divided into tertiles according to NLR: 0.85< NLR ⩽1.85 (n=100, tertile 1), 1.86⩽ NLR ⩽2.46 (n=100, tertile 2), and 2.47⩽ NLR ⩽7.08 (n=100, tertile 3). Patients with RMS were divided into three groups based on the degree of MS as mild, moderate, and severe MS. After the initial evaluation, 187 patients with moderate-to-severe RMS (Group 1) and 113 patients with mild RMS (Group 2) were reassessed. Results: The patients with severe RMS had significantly elevated NLR, mean platelet volume, and pulmonary artery systolic pressure values compared to patients with moderate and mild MS (P<0.001, P<0.001, P<0.001 respectively). Multivariate binary logistic regression analysis revealed that high levels of NLR was an independent predictor of severe RMS (odds ratio =0.68, P=0.008). Moderate-to-severe RMS incidence was significantly higher among patients in the tertile 3 (odds ratio =2.8, P=0.001). Conclusion: NLR is a new inflammatory marker and a simple, rapid, and easily accessible prognostic parameter that can be associated with severity of RMS in patients with RHD. [ABSTRACT FROM AUTHOR]

Blunt chest traumas mostly occur due to car accidents and can cause many cardiac complications such as septal rupture, free-wall rupture, coronary artery dissection or thrombosis, heart failure, arrhythmias, and chordae and papillary muscle rupture. One of the most serious complication is tricuspid regurgitation (TR), which can be simply diagnosed by physical examination and confirmed by echocardiography. We describe a 48-year-old female patient, diagnosed with severe TR 13 years after a blunt chest trauma due to a car accident. TR was diagnosed with transthoracic echocardiography and three dimensional transthoracic echocardiography had defined the exact pathology of the tricuspid valve. The patient underwent successful surgery with bioprosthetic valve implantation and was discharged at 6th postoperative day without any complication. The patient had no problem according to the follow-up one month and six months after operation. [ABSTRACT FROM AUTHOR]

The aim of this study is to investigate the impact of ticagrelor as compared to clopidogrel based dual antiplatelet therapy (DAPT) during post-discharge management on the incidence of left ventricular (LV) thrombus in patients with first acute anterior ST elevation myocardial infarction (STEMI). 641 patients who met the inclusion criteria were divided into two groups based on the receipt of either ticagrelor or clopidogrel based DAPT. Left ventricular thrombus was detected in 73 (11.4%) patients at the first month echocardiographic examination. Ticagrelor based DAPT was associated with significantly less incidence of LV thrombus when compared to clopidogrel [20 (7.4%) vs 53 (14.0%) OR: 0.50 (0.29–0.86)]. Penalized maximum likelihood estimation (PMLE) logistic regression analyses were performed to fourteen candidate variables for identifying the independent predictors of LV thrombus, ticagrelor (compared with clopidogrel) [OR: 0.53 (0.28–0.96), p = 0.039], body mass index (BMI) [OR: 0.58 (0.44–0.77), p < 0.001], KILLIP class (I vs II–IV) [OR: 0.35 (0.14–0.83), p = 0.017], age [OR: 1.22 (1.08–1.40), p < 0.001], poor postprocedural myocardial blush grade (MBG) [OR: 3.35 (1.32–8.15), p = 0.012] and LVEF predischarge [OR: 0.79 (0.72–0.86), p < 0.001] were found to be associated with LV thrombus. Our study demonstrated that the incidence of LV trombus was significantly lower with ticagrelor than clopidogrel-based DAPT during postdischarge treatment for anterior STEMI patients. • Left ventricular thrombus is a potential source of systemic embolization after STEMI. • Prophylactic treatment in addition to DAPT is not recommended after discharge. • Ticagrelor has faster and achieves more consistent P2Y12 inhibition than clopidogrel. • The incidence of left ventricular thrombus is lower with ticagrelor than clopidogrel.

• Considering the worse prognosis of elderly STEMI patients, an identifying the most suitable risk scoring system is crucial. • We observed that the Syntax Score (SS) II was an independent predictor of long-term mortality in octogenarians. • A ROC comparison showed that SSII was a better predictor of long-term mortality than SS, PAMI, TIMI, and GRACE risk scores. • The SSII may be a better predictor of mortality than other risk-scoring systems in octogenarians. The aim of this study was to evaluate the usefulness of the Syntax Score II (SSII) in predicting in-hospital and long-term mortality in octogenarians who presented with ST-segment elevation myocardial infarction (STEMI) and were treated with primary percutaneous coronary intervention (pPCI) in addition to compare SS II with other risk-scoring systems. We retrospectively enrolled 312 consecutive STEMI patients in the eighth decade of life or older who underwent pPCI. The octogenarians were divided into two groups according to their median SSII (low SSII ≤ 43.6 and high SSII > 43.6), and these groups were compared in terms of mortality. The performance of the SSII in predicting patients' outcomes was further compared with that of other well-known risk-scoring systems. In the study, the SSII was an independent predictor of long-term mortality (OR: 1.036 95% CI: 1.005–1.068; p = 0.024). Both in-hospital (20.8% vs. 1.2%; p < 0.001) and long-term mortality (45.0% vs. 11%; p < 0.001) were higher among the patients with a high SSII compared to those with a low SSII. An ROC curve comparison showed that SSII was a better predictor (AUC: 0.807; 95% CI: 0.750-0.863) of long-term mortality than SS, PAMI, TIMI, and GRACE risk scores but not CADILLAC. Based on the study findings, octogenarians with a high SSII had worse in-hospital and long-term survival. The SSII, which includes several clinical and anatomical parameters, may be a better predictor of mortality than other risk-scoring systems in octogenarians. [ABSTRACT FROM AUTHOR]
