Background: A link between preeclampsia (PE) and excessive maternal morbidity and mortality is a commonly recognized fact. Moreover, it has been suggested that chronic inflammatory state connected with PE contributes to accelerated atherosclerosis. There is also an association between PE and maternal cardiac remodeling and biventricular diastolic dysfunction. The aim of the study was to investigate the presence of impaired myocardial performance and increased arterial stiffness in patients who experienced a mild case of PE five years previously. Methods: The study included forty PE patients (40 women; mean age 33.75 +/- 7.95) and 27 healthy volunteers (27 women; mean age 36.44 +/- 10.45) Transthoracic echocardiography, including Doppler echocardiography combined with tissue Doppler imaging (TDI), and aortic stiffness index (AoSI), aortic distensibility (AoD), and aortic elastic modulus (AoEM) values were measured in each study participant. Results: There was a statistically significant increase in hsCRP, aortic stiffness index, and aortic elastic modulus in PE patients as compared to controls (2.43 +/- 1.91 vs. 3.80 +/- 2.06, p=0.007; 3.09 +/- 2.41 vs. 7.32 +/- 6.89, p=0.001; 2.89 +/- 2.11 vs. 7.00 +/- 6.83, p=0.001), while a significant decrease was observed in the aortic strain and distensibility (respectively, 22.35 +/- 15.99 vs. 12.24 +/- 9.22, p=0.005; 11.17 +/- 9.68 vs. 6.13 +/- 4.99, p=0.018). No differences between the two groups were observed with regard to the left ventricular myocardial performance index (MPI) (0.55 +/- 0.16 vs. 0.53 +/- 0.19, p=0.630). Conclusions: To the best of our knowledge, this has been the first study to demonstrate impaired aortic elasticity and unaffected myocardial performance index in patients with mild PE. Moreover, these effects turned out to be significantly correlated with inflammation.
Impaired Coronary Microvascular Function and Increased Intima-Media Thickness in Preeclampsia
(2014) Ciftci, Faika C.; Caliskan, Mustafa; Ciftci, Ozgur; Gullu, Hakan; Uckuyu, Ayla; Toprak, Erzat; Yanik, Filiz; https://orcid.org/0000-0002-6463-6070; https://orcid.org/0000-0003-2579-9755; https://orcid.org/0000-0002-2877-1232; 25455007; A-7318-2017; IXD-5147-2023; GRR-9885-2022
There is an association between preeclampsia (PE) and excessive morbidity and mortality. Some recent studies have revealed the presence of endothelial dysfunction in PE patients with inflammatory activity. Moreover, it has been argued that the chronic inflammatory state involved in PE leads to an acceleration in atherosclerosis. Accordingly, our goal in this study is to determine whether there is any coronary microvascular dysfunction and increase in the intima-media thickness in patients who had mild PE 5 years before, without the presence of any traditional cardiovascular risk factors. The study included 33 mild PE patients (mild preeclampsia is classified as a blood pressure (BP) of 140/90 mm Hg or higher with proteinuria of 0.3 to 3 g/d) whose mean age was 33.7 years old, and 29 healthy women volunteers whose mean age was 36.1 years old. Each subject was examined using transthoracic echocardiography 5 years after their deliveries. During the echocardiographic examination, coronary flow reserve (CFR) and carotid intima-media thickness (IMT) were measured. There was a statistically. lower CFR value in PE patients as compared with controls (2.39 +/- 0.48 vs. 2.90 +/- 0.49; P < .001). On the other hand, there was a significant increase in their IMT and high-sensitivity C-reactive protein (hs-CRP) values (respectively, 0.59 +/- 0.15 vs. 0.46 +/- 0.10; P < .001 and 3.80 +/- 2.10 vs. 2.33 +/- 1.79; P = .004). There was a negative correlation between the CFR values of the PE patients and hs-CRP (r = -0.568; P = .001) and IMT (r = -0.683, P < .001) results. We deteinfined in the study that there was impaired CFR and increased carotid IMT in patients with PE, and, moreover, that these adverse effects were significantly correlated with hs-CRP.

Polycystic Ovary Syndrome: The Correlation Between Renal Doppler Ultrasound and Laboratory Parameters
(2016) Karadeli, Elif; Uckuyu, Ayla; Ciftci, Faika Ceylan; Toprak, Erzat; Turhan, Erdem; Ozcimen, Emel; Niron, Emin Alp
Aim: To investigate whether there is alteration both right and left kidney lenght, parenchymal thickness, renal arterial, venous blood flow measurements in normotensive reproductive age women with polycystic ovary syndrome (PCOS). Material and Method: Forty women with PCOS according to Rotterdam criteria and thirty-six healthy volunteers women were included in our study. Hormonal, biochemical analysis, renal Doppler ultrasonography were performed and were investigated in terms of both left and right renal lenght, parenchymal thickness, peak systolic velocity (PSV), resistive index (RI), venous impedance index (VI), metabolic characteristics having insulin resistance, impaired glucose tolerance, serum lipid concentration. The student t test and pearson corelation test were used for statistical analysis. Results: The measurements for kidneys were not different between women with PCOS and healthy women. The peak systolic velocity of mean renal artery was lower in PCOS group. The mean renal venous impedance also was higher in PCOS group than control group. The mean renal resistive index was slightly higher in PCOS but not statistical significant. In bivariate corelation analyse including all patients, it was seen that BMI, WHR, level of serum fasting glucose, insulin, LDL, trigliserides were positively related with mean renal length and mean parenchymal thickness measurements. Discussion: We found that there was alterations kidney blood flow in normotensive reproductive age women with PCOS. This findings may indicate results of long term renal and cardiovascular complications of PCOS.
