“…15 Baykan et al showed that both systolic and diastolic functions are impaired in patients with CSFP by tissue Doppler imaging analysis of mitral annular velocities. 16 Our study failed to show an association between slow flow and diastolic function. The differences in the studied populations may account for this discrepancy.…”

“…The relationship between CSFP and pro-BNP was not assessed previously. Baykan et al (24) evaluated diastolic function by tissue Doppler technique and found a positive correlation with mean TIMI frame count in patients with CSFP. In our study, the relationship a positive correlation between proBNP and TIMI frame count was determined in patients with CSFP supporting the results of Baykan et al (24).…”

Acute phase reactants in patients with coronary slow flow phenomenonKoroner yavaş akım fenomeni olan hastalarda akut faz reaktanları 416ABSTRACT Objective: In this study, we sought to investigate the serum levels of high sensitivity C-reactive protein (Hs-CRP), N-terminal pro-brain natriuretic peptide (NT proBNP), erythrocyte sedimentation rate, leukocyte, thyroid hormone and fibrinogen levels in patients with coronary slow flow phenomenon (CSFP). Methods: A total of 82 patients with angiographically proven normal coronary arteries and slow coronary flow in all three coronary vessels (45 males and 37 females, mean age 59±11 years) and 34 patients with normal coronary arteries and normal coronary flow (19 males and 15 females, mean age 56±10 years) with similar risk profiles were included in this cross-sectional observational study. Coronary flow rates of all patients and control subjects were documented by Thrombolysis In Myocardial Infarction (TIMI) frame count, serum level of Hs-CRP, NT proBNP, sedimentation, leukocyte, free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH) and fibrinogen levels were measured. Statistical analysis was performed using t test for independent samples, Chi-square test and Pearson correlation analysis.Results: Hs-CRP (0.88±0.86 vs 0.36±0.35 mg/L, p<0.001) and NT proBNP (117.83±163.2 vs 47.33±30.6 ng/ml, p<0.01) were found to be significantly higher in patients with coronary slow flow compared with normal control group. There were no significant differences regarding thyroid hormones, fibrinogen, sedimentation rate and leukocyte count between two groups. The mean TIMI frame counts were positively correlated (r=0.454, p=0.001 and r=0.554, p=0.001, respectively) with plasma Hs-CRP levels and NT-proBNP levels.

Giriş: Koroner yavaş akım (KYA) fenomeni anjiyografik olarak koroner arterleri normal olan veya tıkayıcı kritik darlığı olmayan hastalarda koroner anjiyografi sırasında distal koroner arterlere opak madde ulaşmasının yavaş olmasıdır. Gerilim (strain) görüntülemesi tekniği hem global hem de bölgesel kalp fonksiyonları değerlendirmesinde oldukça güvenilir bir yöntemdir. Bu çalışmada sol ventrikül diyastolik disfonksiyonunun en iyi girişimsel olmayan göstericisi olan sol atriyal strain değeri ile koroner yavaş akım arasındaki ilişkiyi araştırmayı planladık. Hastalar ve Yöntem:Hastanemizde Ocak 2016 ve Aralık 2016 tarihleri arasında koroner anjiyografi yapılmış ve KYA saptanan ardışık 38 hasta çalışmaya alınmıştır. Yaş ve cinsiyet açısından çalışma grubu ile benzerlik gösteren ve normal koroner arterler saptanan 37 hasta ise kontrol grubu olarak çalışmamıza dahil edilmiştir. Bulgular:Hastaların yaş ortalaması 52 ± 10.4 ve erkek cinsiyet oranı %54.1'dir. Kontrol grubu ile kıyaslandığında global pik atriyal longitidunal strain (PALS) ve pik atriyal kontraksiyon strain (PACS) değerlerinin KYA grubunda azaldığını bulduk (32.84 ± 8.06'ya karşı 38.49 ± 6.42, p= 0.001 ve < 0.001, sırasıyla). Bununla birlikte pik longitidunal straine ulaşma süresi (TPLS)'nin koroner yavaş akım tespit edilen hastalarda daha uzun olduğunu tespit ettik (445 ± 58'e karşı 407 ± 36, p= 0.001).Sonuç: Koroner yavaş akım ile sol ventrikül diyastolik disfonksiyonun ilişkili olduğu ve speckle trecking yöntemi ile ölçülen sol atriyal strain değerinin invaziv ölçümler kadar sol ventrikül doluş basıncını gösterdiği bilinmektedir. Biz çalışmamızda kolaylıkla uygulanabilen, ucuz ve girişimsel olmayan bir yöntem olan sol atrial strain parametresi ile koroner yavaş akım arasında pozitif bir ilişki saptadık.Anahtar Kelimeler: Speckle tracking; sol atriyal strain; koroner yavaş akım Relation Between Left Atrial Strain Function and Coronary Slow Flow Phenomenon Using Two-Dimensional Speckle-Tracking Echocardiography ABSTRACTIntroduction: Coronary slow flow (CSF) phenomenon is a clinical entity characterized by a slow, opaque material reaching distal coronary arteries in patients with normal or noncritical coronary artery diseases. Strain imaging techniques are reliable methods for evaluating both global and regional cardiac functions. In this study, we planned to investigate the relationship between left atrial strain (LAS), which is the best noninvasive demonstrator of left ventricle diastolic dysfunction, and CSF.Patients and Methods: Thirty-eight consecutive patients whose coronary angiography was performed and CSF was detected at our hospital between January and December 2016 were included in the study. Thirtyseven age and sex matched patients with normal coronary arteries were enrolled as a control group. Results:The median age was 52 ± 10.4 years, and 54.1% patients were male. Peak atrial longitudinal strain and peak atrial contraction strain were lower in the CSF group than in the control group (32.84 ± 8.06 vs. 38.49 ± 6.42, p= 0.001 and p< 0.001, respe...
