Relation of Angiographic Thrombus Burden with Severity of Coronary Artery Disease in Patients with ST Segment Elevation Myocardial Infarction.

BACKGROUND We planned to investigate the relationship of thrombus burden with SYNTAX score in patients with ST elevation myocardial infarction (STEMI). MATERIAL AND METHODS We retrospectively enrolled 780 patients who underwent PPCI in our clinic due to STEMI. Clinical, laboratory, and demographic properties of the patients were recorded. Angiographic coronary thrombus burden was classified using thrombolysis in myocardial infarction (TIMI) thrombus grades. RESULTS Patients with high thrombus burden were older, with higher diabetes prevalence longer pain to balloon time, higher leukocyte count, higher admission troponin, and admission CK-MB concentrations. SYNTAX score was higher and myocardial perfusion grades were lower in patients with high thrombus burden. Multivariate logistic regression analysis revealed SYNTAX score as the strongest predictor of thrombus burden. ROC analysis demonstrated a sensitivity of 75.5%, specificity of 61.2%, and cut-off value of >14 (area under the curve (AUC): 0.702; 95% confidence interval [CI]: 0.773-0.874;P<0.001) for high thrombus burden. CONCLUSIONS SYNTAX score may have additional value in predicting higher thrombus burden besides being a marker of coronary artery disease severity and complexity.

Long-Term Cardiac Remodeling in Elite Athletes: Assessment by Tissue Doppler and Speckle Tracking Echocardiography.

AIMS: Currently, it remains unclear whether there are differences in the long-term physiologic and adaptive changes in an athlete's heart, varying by the type of exercise undertaken. In this study, we used standard and speckle tracking echocardiography (STE) to evaluate the long-term effects of cardiac remodeling, which persisted many years after retiring from professional sports (marathon running and wrestling). METHODS AND RESULTS: Twenty-four marathon runners, 25 wrestlers, and 24 healthy subjects were included in the study. Left ventricular (LV) strain (S) and strain rate (Sr) were evaluated by apical two- (2C), three- (3C), and four-chamber (4C) imaging. Global S and Sr were calculated by averaging the 3 apical views. The participants' mean age was comparable across the 3 groups. Weight, body mass index, LV mass, LV mass index, and relative diastolic wall thickness were higher in wrestlers than the other groups (P < 0.001). Systolic and diastolic functions, evaluated using conventional echocardiography, were comparable among the 3 groups. 2C, 3C, and 4C longitudinal strain (LS), global LS (GLS), and global Sr systolic filling (SrS) values were comparable between the marathon runners and control group; however, GLS, LS-2C, GLSrS, SrS-3C, and SrS-2C values were significantly increased in wrestlers compared with the control group. CONCLUSIONS: Myocardial changes in wrestlers and marathon runners who quit sports after an extensive period were evaluated using standard echocardiographic and STE parameters. Although they had stopped playing active sports more than 10 years earlier, both the structural and functional properties of the heart were maintained in wrestlers.

New inflammatory markers for prediction of non-dipper blood pressure pattern in patients with essential hypertension: Serum YKL-40/Chitinase 3-like protein 1 levels and echocardiographic epicardial adipose tissue thickness.

The aim of the present study was to investigate whether YKL-40 levels and epicardial adipose tissue (EAT) thickness were associated with non-dipping pattern in essential hypertension (HT). Age- and sex-matched 40 dipper hypertensive patients and 40 non-dipper hypertensive patients were included in the study. Non-dippers had significantly increased EAT thickness and higher YKL-40 and high-sensitivity C-reactive protein levels than dippers. Multivariate logistic regression analysis showed that the EAT thickness and serum levels of YKL-40 and high-sensitivity C-reactive protein were independent predictors of non-dipping pattern in essential HT. In essential HT, presence of non-dipping pattern is associated with increased inflammatory response.

Serum YKL-40/chitinase 3-like protein 1 level is an independent predictor of atherosclerosis development in patients with obstructive sleep apnea syndrome.

OBJECTIVE: The inflammatory process plays an important role in the development of cardiovascular complications in patients with obstructive sleep apnea syndrome (OSAS). YKL-40/chitinase 3-like protein 1 is a novel biomarker of systemic inflammation. This study aimed to investigate whether carotid intima-media thickness (CIMT), a useful marker for early atherosclerosis, is associated with serum YKL-40/chitinase 3-like protein 1 levels in patients with normotensive and nondiabetic OSAS. METHODS: The study included 40 OSAS patients and 40 age- sex- and body mass index-matched healthy controls. Serum YKL-40 levels were detected by enzyme-linked immunosorbent assay. CIMT was measured by B-mode ultrasound. RESULTS: The patients with OSAS had significantly increased CIMT and higher YKL-40 and high sensitivity C-reactive protein (hsCRP) levels than those of the controls. CIMT was strongly correlated with serum YKL-40 levels (r=0.694, p<0.001), hsCRP (r=0.622, p<0.001), age (r=0.525, p=0.001), and weakly correlated with apnea-hypopnea index (AHI) (r=0.365, p=0.021) and the percentage of recording time spent (PRTS) of oxygen saturation<90% (r=0.488, p=0.001). Moreover, it was detected that serum YKL-40 levels were strongly correlated with AHI (r=0.617, p<0.001), and weakly correlated with SaO2<90% of PRTS (r=0.394, p=0.012) and hsCRP (r=0.486, p=0.001). In multiple regression analyses, age and serum levels of YKL-40 and hsCRP were found to be independent predictors of CIMT. CONCLUSION: In patients with OSAS, CIMT was increased. This increase was associated with serum YKL-40 level. Increased serum level of YKL-40 may be an early predictor of atherosclerosis development in patients with OSAS.

Determination of correlation among heart rate variability, left atrium global strain, and nighttime blood pressure among patients with tinnitus.

BACKGROUND: We aimed to examine the correlation among nighttime blood pressure, heart rate variability, and left atrium peak systolic global longitudinal strain among patients with subjective tinnitus. MATERIAL AND METHODS: Eighty patients with tinnitus were assigned to Group 1 and 80 healthy individuals were assigned to Group 2. Clinical blood pressure measurements, ambulatory blood pressure monitoring, and Holter electrocardiography monitoring were performed. All of the cases included in the study were examined with conventional echocardiography and 2-dimensional speckle tracking echocardiography. RESULTS: Mean nighttime systolic blood pressure (130.3±5.4) and mean nighttime diastolic blood pressure (82.8±3.9) in Group 1 were higher than in Group 2 (125.1±5.4 and 80.7±4.7, respectively) (p<0.05). Mean heart rate in Group 1 was significantly lower than in Group 2 but there was no statistically significant difference between the groups in terms of heart rate variability parameters and left atrium peak systolic global longitudinal strain values (p>0.05). CONCLUSIONS: Nighttime systolic blood pressure and nighttime diastolic blood pressure were higher among the patients with tinnitus. In light of these results, we can conclude that both clinical blood pressure measurement and ambulatory blood pressure monitoring are important for patients with tinnitus.

Relationship of left atrial global peak systolic strain with left ventricular diastolic dysfunction and brain natriuretic peptide level in patients presenting with non-ST elevation myocardial infarction.

BACKGROUND: In patients presenting with non-ST elevation myocardial infarction, we investigated the relationship of left atrial deformational parameters evaluated by 2-dimensional speckle tracking imaging (2D-STI) with conventional echocardiographic diastolic dysfunction parameters and brain natriuretic peptide level. MATERIAL AND METHODS: We enrolled 74 non-ST segment elevation myocardial infarction patients who were treated with percutaneous coronary intervention and 58 healthy control subjects. Non-ST segment elevation myocardial infarction patients had echocardiographic examination 48 h after the percutaneous coronary intervention procedure and venous blood samples were drawn simultaneously. In addition to conventional echocardiographic parameters, left atrial strain curves were obtained for each patient. Average peak left atrial strain values during left ventricular systole were measured. RESULTS: BNP values were higher in non-ST segment elevation myocardial infarction patients compared to controls. Mean left atrium peak systolic global longitudinal strain in Group 2 (the control group) was higher than in the non-ST segment elevation myocardial infarction group. Left atrium peak systolic global longitudinal strain was significantly correlated with left ventricular ejection fraction. There was a significant inverse correlation between left atrium peak systolic global longitudinal strain and brain natriuretic peptide level, left atrium volume maximum, and left atrium volume minimum. CONCLUSIONS: Our study shows that Left atrium peak systolic global longitudinal strain values decreased consistently with deteriorating systolic and diastolic function in non-ST segment elevation myocardial infarction patients treated with percutaneous coronary intervention. Left atrium peak systolic global longitudinal strain measurements may be helpful as a complimentary method to evaluate diastolic function in this patient population.

Speckle tracking echocardiographic analysis of left ventricular systolic and diastolic functions of young elite athletes with eccentric and concentric type of cardiac remodeling.

AIMS: In individuals who exercise regularly and for extended periods of time, some structural alterations in the heart, called the athlete's heart, develop in time. These alterations vary in type, can be eccentric or concentric, depending on the nature of exercise. Speckle tracking echocardiography (STE) is a novel, angle-independent method that accurately and reliably measures systolic and diastolic functions of the left ventricle (LV) with considerably lower inter-operator variability. METHODS AND RESULTS: Twenty-two marathon runners, 24 wrestlers, and 20 healthy sedentary individuals were included in the study. The average age of subjects is 17.5 ± 2.2 in marathon runners, 16.8 ± 1.9 in wrestlers, and 16.4 ± 1.8 in control group. The parameters of LV longitudinal strain (S), LV longitudinal strain rate systolic (SRS), LV longitudinal strain rate diastolic early filling (SRE), and longitudinal strain rate diastolic late filling (SRA) were evaluated by apical two-, three-, and four-chamber grayscale imaging using the global longitudinal strain (GLS) and GLS rate (GLSR). Conventional echocardiographic parameters demonstrated increased LV diameters and wall thickness in the marathon runners and increased wall thickness without increased LV diameters in the wrestlers. Systolic and diastolic functions were comparable between the marathon runners and wrestlers with conventional echocardiography. Analysis with STE, however, yielded higher systolic strain and strain rates in the athletes. Normalized GLS parameters and end-diastolic volume (EDV) were shown to be correlated. CONCLUSION: Overall, conventional echocardiography can detect some differences between young athletes with eccentric and concentric type of athlete's heart but it is incapable of revealing differences in intrinsic myocardial functions. However, analysis using STE demonstrated increased systolic functions in athletes commensurate with increased load, with unaltered diastolic functions.

Myringosclerosis as a predictor of the requirement for a permanent pacemaker in patients with drug-related atrioventricular block.

AIMS: Drug-related atrioventricular block (DR-AVB) may develop in patients with underlying latent degenerative conduction disorders, especially with antiarrhythmics and antihypertensives. Although, according to the current guidelines, reversal is achieved with cessation of the inducing agent, this is not the case for nearly half of the patients. The pathophysiological processes of DR-AVB and myringosclerosis include systemic inflammation and degeneration. This study investigated the role of myringosclerosis in predicting irreversible high-grade DR-AVB despite drug cessation. METHODS: This observational, non-randomized, prospective study involved 152 patients with high-grade DR-AVB, 72 of whom had reversible DR-AVB and 80 had irreversible DR-AVB and required permanent pacemakers. The patients' demographic, clinical, echocardiographic, and laboratory characteristics were recorded. Otoscopic tympanic membrane examinations for myringosclerosis were performed. RESULTS: There were no major differences in demographic, echocardiographic or laboratory characteristics between the two groups or previous medications. The median monitoring time with a temporary pacemaker was significantly longer in the irreversible than in the reversible group (5 [4-7] days vs. 2 [1-5] days; P<0.001). The incidence of myringosclerosis was significantly higher in the irreversible than in the reversible group (61.3% vs. 22.2%; P=0.001). Multivariate logistic regression analysis showed that myringosclerosis was an independent predictor of irreversible DR-AVB (odds ratio: 1.703, 95% confidence interval: 1.194-3.058; P=0.01). CONCLUSION: Myringosclerosis is a readily available, inexpensive, and non-invasive assessment and is a marker of inflammation and degeneration that can predict irreversible DR-AVB.

Aortic propagation velocity in the prediction of coronary artery disease severity.

AIMS: To investigate the association of the aortic propagation velocity (APV) with coronary artery disease (CAD) in patients with stable angina pectoris (SAP) through SYNTAX scores (SS). METHODS: The study population comprised 214 SAP subjects who received a coronary angiography. The APV and carotid intima-media thickness (CIMT) were examined and SS was calculated. Subjects were grouped following specific SS criteria: SS less than 22 (low) and SS greater than or equal to 22 (high). RESULTS: High SS subjects had lower APV compared to low SS [39.0 (32.0-51.7) vs. 55.0 (45.0-62.0) cm/s, respectively; P<0.001] and higher CIMT (0.86 ± 0.24 vs. 0.74 ± 0.21 mm, respectively; P<0.001). APV demonstrated a negative correlation with the CIMT (r=-0.239, P<0.001), age (r=-0.188, P=0.006) , and SS (r=-0.561, P<0.001) and showed a positive association with LV ejection fraction (r=0.163, P=0.017). APV, CIMT, diabetes, low-density lipoprotein cholesterol (LDL-C), and age were determined to be markers independently of a high SS. CONCLUSION: APV, CIMT, diabetes, LDL-C and age are independently linked to the CAD severity of SAP subjects. Decreased APV, an indicator of subclinical atherosclerosis, may independently help determine the severity of atherosclerotic CAD in SAP patients.

Sinus of Valsalva thrombosis causing peripheral embolism.

A 44-year-old woman was admitted with the diagnosis of peripheral arterial emboli. Peripheral angiography demonstrated total occlusion of the popliteal artery. The obstruction was successfully resolved with a Fogarty arterial embolectomy catheter. Both transthoracic and transesophageal echocardiography showed a mobile, round thrombus in the noncoronary sinus of Valsalva. The patient did not accept surgery, and anticoagulation with warfarin was initiated. One month after treatment, transthoracic echocardiography demonstrated disappearance of the thrombus in the noncoronary sinus of Valsalva. The patient did not experience any recurrent episode of systemic embolization. This is a rare case of peripheral embolism caused by a thrombus in the noncoronary sinus of Valsalva without aneurysm.

Predictors of left atrial remodeling in newly diagnosed hypertensive patients: a speckle-tracking echocardiographic study.

Endothelial dysfunction, oxidative stress, and increased inflammatory activity are the main pathophysiological mechanisms responsible for cardiac remodeling secondary to hypertension. Bilirubin has anti-oxidant, anti-inflammatory, and anti-fibrotic functions. This report's objectives are to determine whether Query identifiers of left atrial (LA) remodeling, total atrial conduction time (TACT) and LA reservoir strain (LARS), are associated with serum total bilirubin levels, and to identify the possible predictors of LA remodeling in newly diagnosed hypertensive subjects. One hundred thirty-four subjects were enrolled in this study. TACT was evaluated by tissue Doppler imaging, and LARS was calculated by speckle-tracking echocardiography. Laboratory parameters were recorded. The subjects were classified into two separate groups according to the median value of TACT and LARS. In patients with supramedian TACT, LA volume index (LAVI) and epicardial adipose tissue (EAT) thickness were higher, while LARS and LVGLS were lower. In subjects with inframedian LARS, TACT was longer, LAVI and EAT thickness were higher, and LVGLS was lower. Patients with supramedian TACT and inframedian LARS were older and had lower total bilirubin. Total bilirubin, EAT thickness, and age were predictors of TACT and LARS. Serum bilirubin levels may have a protective effect on the LA remodeling process in newly diagnosed hypertensive subjects.

Relationship Between C-Reactive Protein to Albumin Ratio and Thrombus Burden in Patients With Acute Coronary Syndrome.

Increased coronary thrombus burden is known to be a strong predictor of adverse cardiovascular (CV) outcomes. C-reactive protein to albumin ratio (CAR) can be used as a surrogate marker of pro-inflammation which is closely related to prothrombotic state. We aimed to evaluate the association between CAR and coronary thrombus burden in patients who presented with acute coronary syndrome (ACS). Patients who presented with ACS and treated with primary percutaneous coronary intervention were included in the study. Patients were divided into 2 groups as high thrombus burden and low thrombus burden. The study population included 347 patients with non-ST-segment elevation myocardial infarction (169 [48.7%]) and ST-segment elevation myocardial infarction (178 [51.3%]). The CAR was significantly higher in patients with higher thrombus burden (24.4 [1.2-30.2] vs 31.9 [2.2-31.3], P < .001). Independent predictors for increased thrombus burden were higher CRP level (odds ratio [OR]: 0.047; 95% confidence interval [CI]: 0.004-0.486; P = .010), lower serum albumin level (OR: 0.057; 95% CI: 0.033-0.990; P = .049), higher CAR (OR: 1.13; 95% CI: 1.03-1.23; P = .008), higher neutrophil-lymphocyte ratio (OR: 1.18; 95% CI: 1.05-1.31; P = .004), and baseline troponin I level (OR: 1.06; 95% CI: 1.01-1.13; P = .017). Novel CAR can be used as a reliable marker for increased coronary thrombus burden that is associated with adverse CV outcomes.

Decreased left atrial strain parameters are associated with prolonged total atrial conduction time in lichen planus.

BACKGROUND: Lichen planus (LP) carries the increased risk of cardiovascular events as it is a chronic inflammatory disease. This study aimed at determining the relationship between total atrial conduction time (TACT), P-wave dispersion, and the left atrium (LA) global strain in the patients with LP. METHODS: Forty people as a control group and 40 patients with LP were included in this study. Patient assessed global longitudinal LA strain by two-dimensional speckle-tracking strain echocardiography. RESULTS: The global peak systolic LA myocardium strain during the left ventricular systole (LAGLSRs) and the global peak negative LA myocardial strain rate during the early ventricular diastole (LAGLSRe) values were significantly lower in the patients with LP in proportion to the control group according to the strain measurements (1.7 ± 0.07 vs. 1.9 ± 0.1%, p = 0.001; 1.23 ± 0.04 vs. 1.2 ± 0.08 s-1, p = 0.001), respectively. TACT value was found to be significantly longer (102.6 ± 6.3 ms) in the patients with LP than the control group (96.3 ± 5.3 ms, p = 0.001), considering the terms of the artial conduction features. CONCLUSION: This study demonstrated that the subclinical cardiac involvement in LP can determine the prolonged TACT and the impaired left atrial myocardial deformation values.

Determinants of Chronic Total Occlusion in Patients With Peripheral Arterial Occlusive Disease.

Chronic total occlusion (CTO) is a common finding in 40% of the patients with peripheral arterial disease (PAD). The aim of this study was to investigate the determinants of CTO in patients with PAD. The study included a total of 211 nonanemic patients with PAD. All patients were categorized according to the Fontaine classification. In lower extremity angiography cohorts, CTO- patients were designated as group 1 and CTO+ patients were designated as group 2. Patients with CTO had significantly higher red cell distribution width (RDW), neutrophil-lymphocyte ratio, uric acid, and high-sensitivity C-reactive protein compared to patients without CTO ( P ≤ .001, P = .036, P ≤ .001, and P = .015, respectively). Albumin, total bilirubin, and direct bilirubin were significantly lower in the patients with CTO compared to patients without CTO ( P = .023, P ≤ .001, and P = .049, respectively). Multivariate logistic regression analysis showed that RDW, uric acid, and total bilirubin were independent predictors of CTO in patients with PAD. We demonstrated that increased RDW and uric acid levels and lower total bilirubin values were independently associated with CTO in patients with PAD.

Beneficial Effects of Ozone Therapy on Oxidative Stress, Cardiac Functions and Clinical Findings in Patients with Heart Failure Reduced Ejection Fraction.

The aim of study was to determine the effects of ozone therapy on the oxidative stress, cardiac functions and clinical findings in patients with heart failure reduced ejection fraction (HFrEF). A total of 40 patients with New York Heart Association 2 and 3 HF with left ventricular ejection fraction (LVEF) <35%, and 40 subjects without HF as control group were included in the study. Patients with HFrEF were given additional ozone therapy of major and minor administrations along with conventional HF treatment for 5 weeks. Before and after ozone therapy, left ventricular end-systolic and end-diastolic volumes (LVESV, LVEDV) and the 6 minute walk distance (6MWD) and blood levels of the superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione peroxidase (GSHPx), malondialdehyde (MDA), nitric oxide (NO) and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured. Ozone therapy significantly reduced the serum levels of NO and MDA (p < 0.001, respectively) and significantly increased the levels of SOD, CAT, GSH and GSHPx (p < 0.001, respectively). LVEDV and LVESV were found to be significantly reduced; however, LVEF was not found to be significantly increased (p = 0.567). As the biochemical improvement marker of HF, NT-proBNP was significantly reduced (p < 0.001). The clinical HF improvement marker of 6 minute walk distance was also modestly increased (p < 0.001). Ozone therapy might be beneficial in terms of activating antioxidant system and merit further therapeutic potential to conventional HF treatment in patients with HFrEF.

Myocardial deformation and total atrial conduction time in the prediction of cardiac involvement in patients with pulmonary sarcoidosis.

AIMS: In this study, we aim to evaluate the left atrial global longitudinal strain (LAGLS), total atrial conduction time (TACT) and left ventricle (LV) functions in recently diagnosed pulmonary sarcoidosis (PS) patients. METHOD: Fifty recently diagnosed PS patients (group 1) and a control group of 50 healthy individuals (group 2) were evaluated in the study. Two-dimensional echocardiography images were obtained from LV apical 4-chamber (4C), long-axis (L) and 2-chamber (2C) views. Peak longitudinal strain and strain rate (SR) were obtained from 4C, L and 2C views. Mean values of the three views were calculated. LV global longitudinal strain and LV-SR torsion were determined as the net differences in the mean rotation between the apical and basal levels. LAGLS and TACT values were calculated. RESULTS: The study found that LAGLS was significantly lower in group 1 than in group 2 (P < 0.05). TACT was also significantly longer in group 1 than in group 2 (respectively group 1: 111.6 ± 15.1 ms; group 2: 103.4 ± 5.8 ms, P < 0.001). There was a significant moderate negative correlation between LAGLS and TACT (r = -0.36, P < 0.05). Patients with sarcoidosis had significantly lower LV longitudinal strain and SR measurements than the control group. Although LV basal rotation (LVR) values were similar in both groups, LVR-apical and LV-torsion (LVTR) values were significantly higher in the patient group (group 1). CONCLUSION: The identification of left atrial and left ventricular myocardial deformation using speckle tracking echocardiography in patients with PS allows subclinical LV dysfunction and subclinical electrophysiologic changes to be detected earlier.
