Z Geburtshilfe Neonatol 2021 Apr 9. Epub 2021 Apr 9.

Department of Cardiology, Pamukkale University, Denizli, Turkey.

Background: The aim of the current study is to compare electrocardiographic and echocardiographic changes in patients with severe preeclampsia (PE) and those with uncomplicated pregnancies.

Methods: This is a case-controlled prospective study consisting of 21 pregnant women with severe preeclampsia and a control group consisting of age- and gestational age-matched 24 healthy pregnant women. All patients underwent electrocardiographic and echocardiographic investigation.

Results: QRS intervals were shorter and PR intervals were longer in the PE group (QRS duration: 80 (60-120) ms and 80 (40-110) ms, p=0.035; PR duration: 160 (100-240) ms and 120 (80-200) ms, respectively; p=0.046). The left ventricular end-systolic diameters of the patients with severe PE group were significantly larger than the control group (31 (24-36) mm and 30 (24-33) mm, respectively; p=0.05). Similarly, posterior wall thickness values of the PE group were significantly higher compared to the control group (9 (7-11) mm vs. 8 (6-10) mm, respectively; p=0.020). Left ventricular mass (146.63±27.73 g and 128.69±23.25 g, respectively; p=0.033) and relative wall thickness values (0.385±0.054 and 0.349±0.046, respectively; p=0.030) were also higher in the PE group. In addition, patients with early-onset severe PE had significantly a higher left ventricular end-diastolic diameter and volume compared with late-onset PE patients.

Conclusions: The structural changes detected in the severe PE group suggest a chronic process rather than an acute effect. In addition, diastolic dysfunction and left ventricular remodeling are most marked in patients with severe early-onset PE.

Arterial stiffness measured by cardio-ankle vascular index is greater in non-obese young women with polycystic ovarian syndrome.

J Obstet Gynaecol Res 2021 Feb 4;47(2):521-528. Epub 2020 Nov 4.

Department of Obstetrics and Gynecology, Pamukkale University Medical School, Denizli, Turkey.

Aim: The association of metabolic abnormalities and polycystic ovarian syndrome (PCOS) has been documented, but few studies have focused on cardiovascular risk in these women. The aim of this study was to compare arterial stiffness by using the cardio-ankle vascular index (CAVI) in PCOS women with controls, and to evaluate whether any clinical or laboratory variables had independent associations with it.

Methods: A group of 160 women, matched for age and body mass index were recruited. Diagnosis of PCOS was made according to the Rotterdam criteria. Arterial stiffness using CAVI was evaluated in non-obese young woman, with and without PCOS.

Results: In the PCOS group (n = 80), 60 cases (75%) had findings of hyperandrogenism, 59 (73.8%) had ovulatory dysfunction, and 70 (87.5%) had an ultrasonographic appearance of polycystic ovaries. Women with PCOS had significantly higher mean CAVI values when compared to subjects without PCOS (5.78 ± 0.64 vs 5.28 ± 0.77, P < 0.001). Multiple regression analysis revealed that androgen excess was associated with increased arterial stiffness, independent of ovulatory dysfunction, polycystic ovaries, body mass index and age.

Conclusion: This data suggests that vascular compliance is decreased in young women with PCOS. Androgen excess is independently associated with increased arterial stiffness.

Molecular and Biochemical Parameters Related to Plasma Mannose Levels in Coronary Artery Disease Among Nondiabetic Patients.

Genet Test Mol Biomarkers 2020 Sep 6;24(9):562-568. Epub 2020 Aug 6.

Department of Cardiology, Faculty of Medicine, Pamukkale University, Denizli, Turkey.

Nondiabetic patients were studied to determine whether modest elevations in plasma mannose may be associated with a greater incidence of coronary artery disease (CAD). Plasma insulin, mannose, glucose, hexokinase 1-2, GLUT1-GLUT4 levels, and serum mannose phosphate isomerase enzyme levels were evaluated with respect to subsequent CAD using records from 120 nondiabetic CAD patients and 120 healthy volunteers. CAD was identified from myocardial infarction and new diagnoses of angina. Of 120 nondiabetic CAD patients studied, their plasma GLUT4 and HK1 levels were significantly lower than those of the control group. In addition, a significant increase in plasma mannose levels was found in the patient group compared to the control group. Our findings showed that elevated baseline mannose levels in plasma are associated with an increased risk of CAD over time.

Effect of invasive strategy on long-term mortality in elderly patients presenting with acute coronary syndrome.

Cardiovasc J Afr 2020 Sep/Oct;31(5):252-256. Epub 2020 Jun 22.

Cardiology Department, Pamukkale University Hospitals, Pamukkale, Denizli, Turkey.

Objective: The elderly have the highest incidence of cardiovascular disease and frequently present with acute coronary syndrome (ACS). In this study, our aim was to evaluate the effect of an invasive strategy on long-term mortality in patients of 80 years and older presenting with ACS.

Methods: Patients who were admitted to hospital with ACS were recruited using appropriate ICD codes in the computerised hospital data system. After exclusion of patients below 80 years old, the remaining 156 patients were involved in the final analyses. Ninety-four of 156 patients (60.3%) underwent coronary angiography and they constituted the invasive-strategy group, whereas the remaining 62 (39.7%) patients were treated medically and they constituted the conservative-strategy group.

Results: Median follow-up duration of patients was 8.5 (0-61) months. Total mortality at the end of the follow-up period was 24 (25.5%) patients in the invasive-strategy group and 30 (48.4%) in the conservative-strategy group (p = 0.006). According to Cox regression analysis, the invasive strategy (OR: 0.26, 95% CI: 0.12-0.56, p = 0.001), presentation with ST-segment elevation myocardial infarction (OR: 7.76, 95% CI: 1.74-34.57, p = 0.002), low ejection fraction below 40% (OR: 3.11, 95% CI: 1.43-6.76, p = 0.004), heart rate (OR: 0.98, 95% CI: 0.96-0.99, p = 0.013) and GRACE risk score between 150 and 170 (OR: 7.76, 95% CI: 1.74-34.57, p = 0.002) were related to long-term mortality.

Conclusions: Our results show the benefit of the invasive strategy on mortality rate in elderly patients over 80 years old and presenting with ACS.

Association of Disease Subtype and Duration with Echocardiographic Evidence of Pulmonary Hypertension in Myeloproliferative Neoplasm.

Med Princ Pract 2020 19;29(5):486-491. Epub 2020 Feb 19.

Department of Cardiology, Faculty of Medicine, Pamukkale University, Denizli, Turkey.

Background: Pulmonary hypertension (PH) can complicate the course of myeloproliferative neoplasms (MPNs). Echocardiography is a useful noninvasive screening test for PH in populations at risk. We aimed to investigate the echocardiographic evidence of PH and clinical characteristics of patients with MPNs.

Methods: This study included 197 patients with MPNs (mean age, 59 ± 14 years; females, 53%; mean disease duration, 3.4 ± 2.8 years). Clinical and laboratory characteristics, including JAK2V617F mutation status, were obtained. All participants underwent a comprehensive transthoracic echocardiographic examination. The echocardiographic evidence of PH was defined as systolic pulmonary artery pressure (SPAP) ≥40 mm Hg.

Results: Overall, 11 patients (5.5%) with SPAP ≥40 mm Hg had echocardiographic evidence of PH. Patients with myelofibrosis had echocardiographic evidence of PH more often than patients with other MPNs (p < 0.001). Disease duration since the diagnosis of MPNs was 6.7 ± 4.6 years in the PH group and 3.1 ± 2.5 years in the non-PH group (p < 0.001). There was a weak positive correlation between SPAP values and time since diagnosis (r = 0.236, p =0.001). JAK2V617F mutation was not associated with PH. In multivariate logistic regression analysis, the presence of myelofibrosis (odds ratio [OR]: 22.177, 95% CI: 4.480-109.790, p < 0.001), long disease duration (OR: 1.217, 95% CI: 1.024-1.447, p = 0.026), and high uric acid levels (OR: 1.868, 95% CI: 1.049-3.328, p = 0.034) were found to be related with the echocardiographic evidence of PH. Survival was worse in the PH group (p = 0.0001).

Conclusion: Our results suggest that patients with myelofibrosis are more likely to develop PH than other MPNs patients. Disease duration may predict the development of PH in MPN patients.

Genome-wide DNA Methylation Profiling of Blood from Monozygotic Twins Discordant for Myocardial Infarction.

In Vivo 2020 Jan-Feb;34(1):361-367

Department of Molecular, Cell and Developmental Biology, David Geffen School of Medicine, University of California, Los Angeles, CA, U.S.A.

Background/aim: This study aimed to measure the DNA methylation state of thousands of CpG islands in the blood of two monozygotic twins that were discordant for cardiovascular disease (CVD). Twin 1 had suffered myocardial infarction, while the other was healthy.

Patients And Methods: Since the aim of this study was to identify differentially methylated regions which might act as potential markers, reduced-representation bisulfite libraries were used for whole-genome methylation analysis.

Results: According to the analysis, 11 genes lipid droplet associated hydrolase (LDAH), apolipoprotein B (APOB), acyl-CoA synthetase medium chain family member 2A (ACSM2A), acyl-CoA synthetase medium chain family member 5(ACSM5), acyl-CoA synthetase family member 3 (ACSF3), carboxylesterase 1 (CES1), carboxylesterase 1 pseudogene 1 (CES1P1), AFG3 like matrix AAA peptidase subunit 2 (AFG3L2), iron-sulfur cluster assembly enzyme (ISCU), SEC14 like lipid binding 2 (SEC14L2) and microsomal triglyceride transfer protein (MTTP) were all hypomethylated in DNA from twin 2, the unaffected twin. Methylation changes were observed at different multiple loci between the twins, suggesting loci that are affected by disease status in identical genetic backgrounds.

Conclusion: This twin study may contribute significantly to the understanding of the genetic basis of CVD and resulting myocardial infarction. This approach may allow identification of possible target loci associated with aberrant epigenetic regulation in CVD.

Predictors of in-hospital mortality in very eldery patients presenting with acute coronary syndrome: A single-center study.

Turk Kardiyol Dern Ars 2019 01;47(1):38-44

Department of Cardiology, Pamukkale University Hospitals, Denizli, Turkey.

Objective: Acute coronary syndrome (ACS) has become more frequent in the elderly population due to increased life expectancy. The aim of this trial was to determine clinical and laboratory factors related to in-hospital mortality in patients over 80 years of age who presented with ACS.

Methods: A total 171 patients (86 men, median age 83 years) who were over 80 years of age and were hospitalized due to a diagnosis of ACS were enrolled in this study. The patients' demographic data, clinical features, and laboratory values were screened retrospectively from hospital records.

Results: During the follow-up period, 19 of 171 patients (11.1%) died. The causes of death were cardiogenic shock (n=6, 31.5%), acute renal failure (n=6, 31.5%), arrhythmia (n=4, 21%), and septic shock (n=3, 15.7%). ST-segment elevation myocardial infarction presentation was more common among those who died [14 (73.7%) vs. 31 (20.5%); p<0.001]. Patients who died during in-hospital follow-up also had higher peak troponin [3.1 ng/mL (7.2) vs. 0.3 ng/mL (1.6); p<0.001] and creatine kinase-MB levels [96.7 ng/mL (194) vs. 10.9 ng/mL (36.2); p<0.001]. The results indicated that a high Global Registry of Acute Coronary Events (GRACE) risk score [odds risk (OR): 1.074, 95% confidence interval (CI): 1.039-1.110; p<0.001], ejection fraction (EF) ≤40% (OR: 8.113, 95% CI: 1.101-59.773; p=0.040), or no use of an angiotensin-converting enzyme inhibitor (ACEI)/angiotensin receptor blocker (ARB) (OR: 0.075, 95% CI: 0.006-0.995; p=0.049) was significantly associated with in-hospital mortality.

Conclusion: Presentation with a high GRACE risk score, no use of an ACEI/ARB, and a low EF at admission were associated with in-hospital mortality in ACS patients more than 80 years old.
