P-wave duration and dispersion in patients with coronary slow flow and its relationship with Thrombolysis in Myocardial Infarction frame count

Aim: P-wave dispersion (PD), and duration has been reported to be associated with inhomogeneous and discontinuous propagation of sinus impulses. The aim of this study was to investigate the PD in patients with coronary slow flow (CSF) phenomenon

Assessment of P-wave duration and dispersion in patients with isolated coronary artery ectasia

Introduction: Coronary artery ectasia (CAE) is defined as localized or diffuse dilatation of the epicardial coronary arteries. We sought to determine whether isolated CAE may alter P-wave duration and dispersion (PD)

The effects of treatment with atorvastatin versus rosuvastatin on endothelial dysfunction in patients with hyperlipidaemia

Demir, Vahit/0000-0001-8349-6651WOS: 000457728400007PubMed: 29528361Introduction: Statins can reduce cardiovascular events and improve endothelial function, However. differences in the effect of statins on endothelial dysfunction have not been researched sufficiently. Here. we aimed to compare the effects of atorvastatin Versus rosuvastatin on endothelial function via flow-mediated ',aid endothelial-independent dilation. Methods: Hyperlipidaemic subjects on treatment with statins for one year (either 20 mg/day atorvastatin or 10 mg/day rosuvastatin) were enrolled in the study. In accordance with the literature, flow-mediated dilation (FMD) and nitrate-mediated endothelium-independent dilation (EID) were measured by ultrasonography on the right brachial artery of each subject. Baseline and final measurements were compa red to each group and between the groups. Results: One hundred and four subjects (50 atorvastatin and 54 rosuvastatin users) were enrolled in the study. Fifty-eight subjects were female. The groups were statistically similar in terms of age and body mass index, and haemoglobin, creatinine, total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein cholesterol levels. In each group, the mean final FMD and LID values were higher compared to their respective baseline values. but the mean changes in FMD and EID were statistically similar in both groups (p = 0.958 for FMD and 0.827 for EID). There was no statistically significant difference between the atorvastatin and rosuvastatin groups in terms of final FMD and EID values (p = 0.122 and 0.115. respectively). Conclusion: This study demonstrated that both one-year atorvastatin and rosuvastatin treatments significantly improved endothelial function, when assessed with FMD and FAD and measured by ultrasonography. However, the amount of improvement in endothelial dysfunction was similar in the two treatments
