The effect of atherogenic plasma index on collateral development in patients with chronic coronary total occlusion
Aim: To demonstrate the correlation between coronary collateral circulation (CCC) and atherogenic plasma index (AIP), one of the factors associated with the formation of collateral vessels.
Methods: Hospital records of patients with chronic total occlusion (100% stenosis) in at least one coronary artery were evaluated. Triglycerides, HDL level, triglyceride/HDL ratio and atherogenic plasma index before coronary angiography were assessed for the 451 patients who met the study criteria.
Results: Comparison of the two groups in terms of laboratory findings showed that triglyceride/HDL ratio (5.04±3.13 vs 3.56±2.12, p<0.001) and AIP (0.63±0.25 vs 0.48±0.25, p<0.001) were higher with statistical significance in the weak collateral group. The ROC analysis revealed an association between weak collateral formation and atherogenic plasma index with 64.7% sensitivity and 66.2% specificity using a cut-off value of 0.58 for AIP. Accordingly, low AIP was found to be an independent predictor of good collateral artery formation.
Conclusion: This study suggests that a high atherogenic plasma index may be an independent factor associated with poor collateral formation
Comparison of the real-life clinical outcomes of warfarin with effective time in therapeutic range and NOACs: Insight from AFTER-2 Trial
BACKGROUND: We aimed to compare the long-term follow-up results of patients with atrial fibrillation (AF) who use vitamin K antagonist (VKA) with effective time in therapeutic range (TTR) and non-vitamin K antagonist oral anticoagulants (NOACs).
METHODS: A total of 1140 patients were followed at 35 different centers for five years. During the follow-up period, the INR values were studied at least 4 times a year and the TTR values were calculated according to the Roosendaal method. The effective TTR level was accepted as >60% as recommended by the guidelines. There were 254 patients in the effective TTR group and 886 patients in the NOACs group. Ischemic cerebrovascular disease/ transient ischemic attack (CVD/TIA), hemorrhagic CVD, and mortality were considered primary endpoints based on one-year and five-year follow-ups.
RESULTS: Ischemic CVD/TIA (3.9% vs. 6.2%; P = 0.17) and hemorrhagic CVD (0.4% vs. 0.5%, P = 0.69), the one-year mortality rate (7.1% vs. 8.1%; P = 0.59), five-year mortality rates (24% vs. 26.3%; P = 0.46) were not different between the effective TTR and NOACs groups during the follow-up respectively. The CHA2DS2-VASC score was similar between warfarin with the effective TTR group and NOACs group (3 [2–4] vs. 3 [2–4]; P = 0.17, respectively]. Additionally, survival free-time did not differ between the warfarin with effective TTR group and each NOAC in the Kaplan-Meier analysis (dabigatran, P = 0.59; rivaroxaban, P = 0.34; apixaban, P = 0.26; and edoxaban, P = 0.14).
CONCLUSION: There was no significant difference in primary outcomes between the effective TTR and NOAC groups in AF patients
Evaluation of Right Ventricular Global Longitudinal Strain in COVID-19 Patients After Intensive Care Unit Discharge
Background and Aim:Using two-dimensional speckle tracking echocardiography (2D-STE), the ventricular functions of hospitalized coronavirus disease-2019 (COVID-19) patients were assessed. However, there is limited information about cardiac functions in the first year after recovery from the intensive care unit (ICU). This research aims to assess the right ventricular functions of COVID-19 patients and their changes within the first year after ICU discharge using 2D-STE.Materials and Methods:The study was conducted prospectively. The study included 68 consecutive patients and 70 control patients. Echocardiography was performed in the ICU and the first year after discharge from the hospital. Right ventricular global longitudinal strain (RVGLS) was measured using the 2D-STE method.Results:The mean age of the study group was 48.67±8.10 and 37 (54.4%) patients were males. There were no substantial differences across the groups, including age, gender, body mass index, heart rate, diabetes, dyslipidemia, and smoking (P > 0.05). A substantially significant positive correlation was detected between right ventricular dimension (RAD) (r = 0.644, P < 0.001), right ventricular diastolic dimension (RVDD) (r = 0.573, P < 0.001), ferritin (r = 0.454, P < 0.001), D-dimer (r = 0.305, P = 0.011) values and RVGLS in the in-hospital and after-discharge first-year groups. The RVGLS values of the control, in-hospital, and after-discharge first-year groups were -20.36±3.06, -16.98±3.78, and -17.58±6.45, indicating a statistically significant difference across the groups (P < 0.001). Tricuspid annular plane systolic excursion was higher in the control group (P < 0.05).Conclusion:RVGLS was found to be depressed during the in-hospital period and showed no improvement in the 1 year post discharge
The effect of coronary slow flow on ventricular repolarization parameters
Introduction: Ischemia due to microvascular dysfunction may be responsible for the heterogeneity of ventricular
repolarization in coronary slow flow. To our knowledge, there is no study in which QT interval, Tp-Te interval,
index of cardiac-electrophysiological balance (iCEB), and frontal QRS-T angle were evaluated together in patients with CSF. In this study, we examined for the first time the relationship between all these myocardial
repolarization parameters and CSF.
Materials and methods: The study group included 178 patients (99 female, mean age: 50.6 ± 8.6 years) with
isolated CSF without stenotic lesions and with angiographically proven normal coronary arteries. The control
group included 120 patients (71 female, mean age: 49.3 ± 9.4 years) with normal coronary angiography. QRS
duration, QT interval, QTc interval, Tp-Te interval, Tp-Te/QT, Tp- Te/QTc, iCEB score, and frontal QRS-T angle
were calculated from 12‑lead ECGs.
Results: There was no significant difference in demographic parameters between the two groups. Compared with
the control group, patients with CSF had significantly longer QTmax duration, QT dispersion, Tp-Te interval, and
higher iCEB score, wider frontal QRS-T angle.
Conclusion: In our study, we found that many of the ventricular repolarization parameters were adversely
affected in patients with CSF. Impaired parameters may be associated with the risk of malignant ventricular
arrhythmias
The prognostic value of ORBIT risk score in predicting major bleeding in patients with acute coronary syndrome
Background: The most significant adverse effect of antithrombotic medication in acute coronary syndrome (ACS) is major bleeding, which is related to increased mortality. Studies on ORBIT risk score in predicting major bleeding in ACS patients are limited.
Objective: This research aimed to examine whether the ORBIT score calculated at the bedside can identify major bleeding risk in patients with ACS.
Methods: This research was retrospective, observational, and conducted at a single center. Analyses of receiver operating characteristics (ROC) were utilized to define the diagnostic value of CRUSADE and ORBIT scores. The predictive performances of the two scores were compared using DeLong's method. Discrimination and reclassification performances were evaluated by the integrated discrimination improvement (IDI), and net reclassification improvement (NRI).
Results: The study included 771 patients with ACS. The mean age was 68.7 ± 8.6 years, with 35.3 % females. 31 patients had major bleeding. Twenty-three of these patients were BARC 3 A, five were BARC 3 B, and three were BARC 3 C. Bleeding history [OR (95 % CI), 2.46 (1.02-5.94), p = 0.021], hemoglobin levels [OR (95 % CI), 0.54 (0.45-0.63), p 74 years [OR (95 % CI), 1.03 (1.01-1.06), p = 0.039] were independent predictors of major bleeding. The ORBIT score was an independent predictor of major bleeding in the multivariate analysis: continuous variables [OR (95 % CI), 2.53 (2.61-3.95), p < 0.001] and risk categories [OR (95 % CI), 3.06 (1.69-5.52), p < 0.001]. Comparison of c-indexes for major bleeding events revealed a non-significant difference for the discriminative ability of the two tested scores (p = 0.07) with a continuous NRI of 6.6 % (p = 0.026) and an IDI of 4.2 % (p < 0.001).
Conclusion: In ACS patients, the ORBIT score independently predicted major bleeding
Usefulness of Eosinophil-Lymphocyte Ratio to Predict Stent Restenosis
Objective: Stent restenosis (SR) is an important complication of percutaneous coronary intervention. There are many studies explored the relation of eosinophils with SR, however, there is no data about relationship between eosinophil-lymphocyte ratio (ELR) and SR. In this study we aimed to investigate the relationship between the value of ELR on admission and SR.
Methods: The study was included 314 patients who had been applied a coronary stent implantation and they were admitted to cardiology clinic with stabile angina and underwent repeat coronary angiography. The data obtained from patients were analyzed retrospectively. The patient group was consisted of 197 patients who were diagnosed as SR, and the control group was consisted of 117 patients whose stents were patent angiographically.
Results: The groups were similar in terms of age, gender, hypertension, diabetes mellitus, LDL-C, HDL-C, platelet count, platelet-lymphocyte ratio (PLR), hemoglobin and left ventricle ejection fraction (LVEF). White blood cell (WBC), neutrophil, eosinophil, C-reactive protein (CRP), ELR and neutrophil-lymphocyte ratio (NLR) on admission were higher in the SR group compared to the controls. All patients were categorized into two groups according to ELR values and SR was more frequent in the high ELR group compared to low ELR group. An ELR value of ≥0.745 predicted SR with 64% sensitivity and 61% specifity.
Conclusion: In this study ELR was found statistically higher in SR patients compared to the controls. According to our data ELR as an inexpensive and easy method, may contribute to determination of high risk patients and increased ELR can be used as a predictor of SR
The effect of idiopathic premature ventricular complexes on left ventricular ejection fraction
Aim Current literature lacks a definitive threshold of idiopathic
premature ventricular complex (PVC) burden for predicting cardiomyopathy
(CMP). The main objective of the present study was to evaluate
relationship between the PVC burden and left ventricular ejection
fraction (LVEF).
Method This multicenter, cross-sectional study included 341 consecutive
patients with more than 1,000 idiopathic PVC in 24 hr of Holter
monitoring admitted to the cardiology clinics between January 2019 and
May 2019 in the nineteen different centers. The primary outcome was the
LVEF measured during the echocardiographic examination.
Result Overall, the median age was 50 (38-60) and 139 (49.4\%) were
female. Percentage of median PVC burden was 9\% (IQR: 4\%-17.4\%).
Median LVEF was found 60\% (55-65). We used proportional odds logistic
regression method to examine the relationship between continuous LVEF
and candidate predictors. Increase in PVC burden (\%) (regression
coefficient (RE) -0.644 and 95\% CI -1.063, -0.225, p < .001), PVC QRS
duration (RE-0.191 and 95\% CI -0.529, 0.148, p = .049), and age
(RE-0.249 and 95\% CI -0.442, -0.056, p = .018) were associated with
decrease in LVEF. This inverse relationship between the PVC burden and
LVEF become more prominent when PVC burden was above 5\%. A nomogram
developed to estimate the individual risk for decrease in LVEF.
Conclusion Our study showed that increase in PVC burden \%, age, and PVC
QRS duration were independently associated with decrease in LVEF in
patients with idiopathic PVC. Also, inverse relationship between PVC
burden and LVEF was observed in lower PVC burden than previously known
