Assessment of right ventricular dysfunction in patients with mitral stenosis: A speckle tracking study.

J Clin Ultrasound 2020 Jun 3;48(5):269-274. Epub 2019 Dec 3.

Department of Cardiology, University of Health Sciences, Erzurum Education and Research Hospital, Erzurum, Turkey.

Purpose: Although it is affected at an early stage, there is a lack of studies investigating right ventricular (RV) function in patients with mitral stenosis (MS). We aimed to investigate the correlation between conventional echocardiographic variables and tricuspid annular plane systolic excursion (TAPSE), used as an indicator of RV dysfunction.

Methods: We enrolled 59 consecutive patients with MS and assigned them in group 1 if TAPSE ≤16, or group 2 if: TAPSE >16.

Results: The mean age of the patients was 42.2 ± 8 years, and 74.6% were females. In univariate analysis, maximal mitral valve gradient, mean mitral valve gradient, systolic pulmonary arterial pressure, RV strain, and RV strain rates were associated with RV dysfunction. In multivariate analysis, both strain variables were found to be independent predictors of RV dysfunction. Kaplan Maier survival analysis showed that patients with lower RV strain had more rehospitalization rate during the one-year follow-up period.

Conclusions: RV dysfunction is common in patients with MS and is associated with higher rehospitalization rate and morbidity. Evaluation of RV strain and strain rate for early detection of RV dysfunction and prediction of rehospitalization may be an appropriate approach in mitral stenosis.

The association between CRP / Albumin ratio and in-stent restenosis development in patients with ST-segment elevation myocardial infarction.

J Clin Lab Anal 2019 May 8;33(4):e22848. Epub 2019 Feb 8.

Department of Cardiology, Erzurum Training and Research Hospital, Erzurum, Turkey.

Background: Although interventional methods are the first-line treatment options in ST-segment elevation myocardial infarction (STEMI), the incidence of stent restenosis (SR) is frequent. We investigated the relationship between CRP/albumin ratio (CAR), a novel indicator of inflammatory response, and SR in this study.

Method: This study was carried out on the patients who underwent coronary angiography in our clinic between January 2017 and September 2017. Two groups were generated according to restenosis status (group 1: restenosis (-), group 2: restenosis (+)), and clinical biochemical and angiographical features were compared. As baseline demographic and angiographic characteristics are slightly different in two groups, propensity score matching analysis was performed to reduce bias. 45 SR patients were matched on a 1:1 basis were enrolled final cohort.

Results: The mean age of the patients was 55 ± 5.1 and 80% were male; Cox regression model was performed to demonstrate independent predictor of restenosis development; and during the one-year follow-up period, CAR (P < 0.001) was found an independent predictor of SR CONCLUSION: In this study, we demonstrate that there may be a strong relationship between SR development and CAR. We implied that inflammatory reaction may be an important diagnostic tool for prediction of SR development in STEMI patients.

The Comparison of Angiographic Scoring Systems With the Predictors of Atherosclerosis.

Angiology 2018 Feb 8;69(2):158-163. Epub 2017 Jun 8.

1 Department of Cardiology, University of Health Sciences, Erzurum Education and Research Hospital, Erzurum, Turkey.

Syntax score (SS) and Gensini score (GS) are used to determine the complexity and severity of coronary artery disease. Although there are some studies indicating the individual relationship of these scoring systems with the carotid intima-media thickness (cIMT) and epicardial fat tissue (EFT), there was no previous study that compared the SS and GS in that respect. We aimed to assess the relationship of SS and GS with predictors of atherosclerosis. We enrolled 522 patients. There were positive correlations between GS and SS tertiles with cIMT and EFT. According to multivariate linear regression analysis for GS, EFT (β: 0.035, t: 2.63, and P = .49) and cIMT (β: 0.339, t: 2.97, and P = .053) were not independently associated. For SS, EFT (β: 0.009, t: 6.5, and P = .006) and cIMT (β: 1.2, t: 10.1, and P = .001) were independently and significantly associated. We showed that the SS is significantly associated more with surrogate markers of atherosclerosis such as EFT and cIMT than the GS.

An isolated single L-II type coronary artery anomaly: A rare coronary anomaly.

Intractable Rare Dis Res 2015 Nov;4(4):203-6

Department of Radiology, School of Medicine, Ataturk University, Erzurum, Turkey.

The incidence of congenital artery anomalies is 0.2-1.4%, and most are benign. Single coronary artery (SCA) anomalies are very rare. The right coronary artery (RCA) originating from the left coronary system is one such SCA anomaly, and the risk of sudden cardiac death (SCD) increases if it courses between the pulmonary artery and aorta and coexists with other congenital heart diseases. Additionally, coursing of the RCA between the great vessels increases the risk of atherosclerosis. We herein present the case of a 57 year-old man who was admitted to our cardiology outpatient clinic and diagnosed with an SCA anomaly in which the RCA arose from the left main coronary artery (LMCA) and coursed between the pulmonary artery and aorta. However a critical stenosis was not detected in imaging techniques, and myocardial perfusion scintigraphic evidence of ischaemia was found in a small area. Therefore, he was managed with conservative medical therapy.

Coronary Artery Disease Risk Factors, Coronary Artery Calcification and Coronary Bypass Surgery.

J Clin Diagn Res 2015 May 1;9(5):OC06-10. Epub 2015 May 1.

Faculty, Department of Cardiology, Istanbul Bilim University, Florence Nightingale Hospital , Department of Cardiology, Istanbul, Turkey .

Introduction: Atherosclerosis is an intimal disease which affects large and medium size arteries including aorta and carotid, coronary, cerebral and radial arteries. Calcium accumulated in the coronary arterial plaques have substantial contribution to the plaque volume. The aim of our study is to investigate the relationship between coronary artery disease (CAD) risk factors and coronary arterial calcification, and to delineate the importance of CACS in coronary artery bypass surgery.

Materials And Methods: The current study is retrospective and 410 patients admitted to our clinic with atypical chest pain and without known CAD were included. These individuals were evaluated by 16 slice electron beam computed tomography with suspicion of CAD and their calcium scores were calculated. Detailed demographic and medical history were obtained from all of the patients.

Results: In our study, we employed five different analyses using different coronary arterial calcification score (CACS) thresold levels reported in previous studies. All of the analyses, performed according to the previously defined thresold levels, showed that risk factors had strong positive relationship with CACS as mentioned in previous studies.

Conclusion: Coronary arterial calcification is part of the athero-sclerotic process and although it can be detected in atherosclerotic vessel, it is absent in a normal vessel. It can be concluded that the clinical scores, even they are helpful, have some limitations in a significant part of the population for cardiovascular risk determination. It is important for an anastomosis region to be noncalcified in coronary bypass surgery. In a coronary artery, it will be helpness for showing of calcific field and anostomosis spot.

The evaluation of the clinical utility of urocortin 1 and adrenomedullin versus proBNP in systolic heart failure.

Anatol J Cardiol 2017 Mar 25;17(3):184-190. Epub 2014 Dec 25.

Clinic of Cardiology, Erzurum Research and Training Hospital; Erzurum-Turkey.

Objective: Urocortin 1 (UCN1) has vasodilator, diuretic, and natriuretic effects, and its expression increases in heart failure (HF). Adrenomedullin (ADM) increases cardiac output and lowers blood pressure in healthy men and in patients with heart failure. The aim of the study was to determine UCN1 and ADM levels in patients with HF, to evaluate the relationship of UCN1 and ADM with various clinical parameters, and to assess UCN1 and ADM as diagnostic markers in HF, in comparison with pro-brain natriuretic peptide (pro-BNP).

Methods: We investigated serum levels of UCN1, ADM, and pro BNP in 86 consecutive patients with systolic HF [ejection fraction (EF) ≤45%] and 85 healthy controls. Serum UCN1, ADM, and pro-BNP levels were measured with the ELISA method. Transthoracic echocardiography was performed to determine left ventricular EF and pulmonary artery systolic pressure.

Results: UCN1 and ADM levels were higher in HF patients (446.2±145.7 pg/mL, p<0.001; 87.9±4.2 pg/mL, p<0.001 respectively). UCN1 was positively correlated with pro-BNP (r=0.963, p<0.001), ADM (r=0.915, p<0.001), and NYHA (r=0.879, p<0.001); ADM was positively correlated with pro-BNP (r=0.956, p<0.001) and NYHA (r=0.944, p<0.001). Receiver operating characteristic curves yielded an area under the curve of 1.00 (p<0.001) for UCN1, 1.00 (p<0.001) for ADM, and 0.99 (p<0.001) for pro-BNP in the diagnosis of HF.

Conclusion: UCN1 and ADM increase with worsening HF and left ventricular dysfunction. They may be used as diagnostic biomarkers in systolic HF, but the incremental value of measuring UCN1 and ADM in patients tested for pro-BNP is questionable.

Swallowed a needle stuck in heart.

Ulus Travma Acil Cerrahi Derg 2014 Jul;20(4):308-10

Department of Cardiovascular Surgery, Erzurum Region Training and Research Hospital, Erzurum, Turkey.

Cardiac tamponade (CT) is a clinical entity characterized by hemodynamic insufficiency resulting from increased intrapericardial pressure due to accumulation of contents such as serous fluid, blood, and pus. CT is a treatable cause of cardiogenic shock, which can be fatal unless diagnosed promptly. Dyspnea, chest pain, hypotension, tachycardia, pulsus paradoxus, raised jugular venous pressure, muffled heart sounds, decreased electrocardiographic voltage, and enlarged cardiac silhouette on chest X-ray are the major clinical signs in CT. Idiopathic or viral pericardititis, iatrogenic trauma during percutaneous coronary interventions or coronary artery bypass grafting, external trauma, malignancies, acute or chronic kidney disease, collagen vascular diseases, tuberculosis, radiation on the chest wall, hypothyroidism and aortic dissection are the etiologic factors. Herein, we present a case of surgically treated CT, which was diagnosed in the third day of ingestion of a sewing needle.

Assessment of the relationship between nondipping phenomenon and microvolt T-wave alternans.

Blood Press Monit 2015 Feb;20(1):2-7

aCardiology Department, Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Training and Research Hospital bCardiology Department, Acibadem University Hospital, Istanbul cCardiology Department, Regional Training and Research Hospital, Erzurum, Turkey.

Objective: The aim of this cross-sectional study was to evaluate microvolt T-wave alternans (MTWA) as a marker of myocardial electrical instability in normotensive and hypertensive individuals with either nondipper or dipper-type circadian rhythm of blood pressure.

Materials And Methods: The study group included a total of 181 patients: 118 hypertensive patients and 63 normotensive healthy volunteers [mean age 46 ± 8; 34 men (54%)]. The patients with hypertension were divided into two groups on the basis of their results of 24-h ambulatory blood pressure monitoring: 61 patients with dipper hypertension [mean age 46 ± 6; 32 men (52.5%)] and 57 patients with nondipper hypertension [mean age 48 ± 10; 36 men (63.2%)]. The MTWAs of all patients were analyzed using the time-domain modified moving average method by means of a treadmill exercise stress test.

Results: MTWA positivity was statistically significantly different between all groups. Left ventricular mass index, E/E', interventricular septum, posterior wall, 24-h systolic blood pressure and diastolic blood pressure, and night-time systolic blood pressure and diastolic blood pressure were correlated positively with MTWA. Left ventricular mass index and the presence of nondipper hypertension were determined to be independent predictors of MTWA positivity.

Conclusion: The blunting of the nocturnal decrease in blood pressure was associated with MTWA positivity in hypertensive patients.

Assessment of mean platelet volume and soluble CD40 ligand levels in patients with non-dipper hypertension, dippers and normotensives.

Clin Exp Hypertens 2015 27;37(1):70-4. Epub 2014 May 27.

Cardiology Department, Mehmet Akif Ersoy Thoracic and Cardiovascular Surgery Training and Research Hospital , Istanbul , Turkey .

Unlabelled: Abstract Objective: Patients with a lack of nocturnal decline in blood pressure (BP) are at an increased risk for cardiovascular events. Mean platelet volume (MPV) and soluble CD40 ligand (sCD40L) are accepted biomarkers of platelet activation and considered as a risk factor for cardiovascular disease. The aim of this study was to determine whether MPV and sCD40L levels are higher in non-dipper hypertensive (NDHT) patients than in dipper hypertensive (DHT) patients and healthy controls.

Methods: 124 consecutive patients were included to this study. Patients were divided into three groups: NDHT patient group [n = 43; mean age 51.8 ± 6.6; 31 males (72.1%)]; DHT patient group [n = 41; mean age 50.2 ± 7.3; 22 males (53.7%)]; and normotensive group [n = 40; mean age 49.9 ± 6.7; 22 males (55%)]. Physical examination, laboratory work-up and 24-h ABPM were performed for all participants.

Results: The sCD40L and MPV levels were significantly higher in the NDHT group than in the DHT and normotensive groups (p < 0.05). In correlation analysis, MPV, 24-h systolic blood pressure (SBP), 24-h diastolic blood pressure (DBP), night-time SBP and night-time DBP were positively correlated with sCD40L.

Conclusion: Our study demonstrated that MPV and sCD40L levels were significantly higher in NDHT patients compared to DHT and normotensive patients. sCD40L levels were positively correlated with MPV, 24-h SBP, 24-h DBP, night-time SBP and night-time DBP.

Increased mean platelet volume associated with extent of slow coronary flow.

Cardiol J 2012 ;19(4):355-62

Department of Cardiology, Balikesir University, School of Medicine, Balikesir, Turkey.

Background: Slow coronary flow (SCF) is characterized by delayed opacification of epicardial coronary vessels. SCF can cause ischemia and sudden cardiac death. We investigated the association between presence and extent of SCF, and cardiovascular risk factors and hematologic indices.

Methods: In this study, 2467 patients who received coronary angiography for suspected or known ischemic heart disease were retrospectively evaluated between April 2009 and November 2010. Following the application of exclusion criteria, our study population consisted of 57 SCF patients (experimental group) and 90 patients with age- and gender-matched subjects who proved to have normal coronary angiograms (control group). Baseline hematologic indices were measured by the automated complete blood count (CBC) analysis. The groups were evaluated for cardiovascular risk factors and medications. Patients were categorized based on the angiographic findings of vessels with or without SCF. Moreover, patients with SCF were divided into subgroups relative to the extent of SCF.

Results: Among the 147 patients (mean age 52.7 ± 10.0, 53.7% male), mean platelet volume (MPV) ranged from 6.5 fL to 11.7 fL (median 7.9 fL, mean 8.1 ± 0.8 fL). Diabetes (OR = 3.64, 95% CI 1.15-10.43, p = 0.03), hypercholesterolemia (OR = 4.94, 95% CI 1.99-12.21, p = 0.001), smoking (OR = 3.54, 95% CI 1.43-8.72, p = 0.006), hemoglobin (OR = 1.69, 95% CI 1.22-2.36, p = 0.002), and MPV (OR = 2.52, 95% CI 1.43-4.44, p = 0.001) were found to be the independent correlates of SCF presence. Only MPV (OR = 2.13, 95% CI 1.05-4.33, p = 0.03) was identified as an independent correlate of extent of SCF.

Conclusions: Elevated baseline MPV value was found to be an independent predictor of the presence and extent of SCF.

Relation of red cell distribution width with presence and severity of coronary artery ectasia.

Clin Appl Thromb Hemost 2012 Sep 21;18(5):441-7. Epub 2012 May 21.

Department of Cardiology, Balikesir University, School of Medicine, Balıkesir, Turkey.

Red cell distribution width (RDW) is an index that has been shown to be an independent correlate of adverse outcomes in some cardiac conditions. Isolated coronary artery ectasia (CAE) is an abnormality of the coronary anatomy and can cause ischemia. We hypothesized that increased RDW would be associated with isolated CAE because both are associated with inflammation. In this study, 2345 patients who received coronary angiography were retrospectively evaluated. After exclusion, 75 patients with isolated CAE and 96 consecutive patients with normal coronary were included in the study. The severity of isolated CAE was determined according to the Markis classification. Baseline RDW was measured as part of the automated complete blood count. Red cell distribution width was observed to be an independent predictor of both presence and severity of isolated CAE. In conclusion, RDW is associated with both the presence and severity of isolated CAE.
