Aim: Central retinal artery occlusion (CRAO) leads to significant, non-painful loss of sight due to retinal infarction. Most CRAO patients have atherosclerotic risk factors. Pulse wave velocity (PWV) and Flow-mediated dilatation (FMD) can provide insights into the onset and development of atherosclerosis. This research aims to assess arterial stiffness measures and identify endothelial dysfunction in individuals with CRAO. Materials and Methods: 33 consecutive CRAO patients (63 ± 7 years, 21 men (63.6%)) were recruited in the study. 35 age/sex-matched participants were included as a control group. FMD and PWV were measured from the brachial artery, as indicators of endothelial dysfunction and atherosclerosis in the arterial wall, respectively. Additionally, the transthoracic echocardiographic parameters of the patients were investigated. Results: CRAO patients had significantly higher frequencies of hypertension, hyperlipidemia, and smoking status. Furthermore, the frequency of diabetes was also higher in the CRAO group, but this difference did not reach statistical significance. CRAO patients showed markedly elevated PWV and reduced FMD. However, no notable differences were observed between groups in terms of left ventricle systolic and diastolic functions. Conclusion: Our study showed that CRAO patients may have increased arterial stiffness and endothelial dysfunction. Systemic endothelial dysfunction and atherosclerosis may be linked to the development of CRAO. [ABSTRACT FROM AUTHOR]

Objective: During the COVID-19 pandemic, many patients have experienced cardiovascular complications, including a variety of arrhythmias. The aim of our study was to evaluate the acute electrocardiography (ECG) changes and post-COVID arrhythmia incidence in patients with acute COVID-19 infection. Patients and Methods: One hundred hospitalized COVID-19 patients were consecutively included. Patients were divided into two groups according to their troponin levels. Thirty subjects were included as controls. All patients underwent daily 12-lead ECG during hospitalization and were followed up for at least 12 months, by performing ECG and ambulatory ECG monitoring and questioning their symptoms at 3-month intervals. Results: Thirty-one patients had elevated high sensitive cardiac troponin I (hs-cTnI). These patients had significantly longer QT dispersion compared to COVID-19 patients with normal troponin levels and controls. Regardless of troponin elevation, COVID-19 patients had significantly longer Tp-e intervals and P wave (PW) durations compared to controls. During the follow-up period; palpitation, beta-blocker usage, and inappropriate sinus tachycardia were more common in the COVID-19 group with hs-cTnI than control group. Conclusion: COVID-19 causes prolongation in PW durations, Tp-e intervals, and QT dispersion during acute infection, which may lead to arrhythmias in these patients. The higher incidence of inappropriate sinus tachycardia in COVID-19 patients with elevated troponin levels may be a sign of myocardial involvement. [ABSTRACT FROM AUTHOR]

Introduction: Re-establishing "dipping" physiology significantly reduces cardiovascular events. The aim was to investigate the effect of timing of fixed dose triple antihypertensive combinations on blood pressure (BP) control. Methods: One hundred sixteen consecutive patients (62.7 ± 10.7 years, 38 men) with grade II hypertension were randomized into four groups. Group 1 and Group 2 patients were given angiotensin converting enzyme inhibitor-based triple antihypertensive pills to be taken in the morning or evening, respectively while Group 3 and Group 4 patients were given angiotensin receptor blocker (ARB) based triple antihypertensive pills to be taken in the morning or evening, respectively. All patients underwent 24-h ambulatory BP monitoring 1 month after the initiation of treatment. Results: There were not any significant differences in the characteristics, BP values and loads among groups. All patients in each group had good BP control. Dipping pattern in systolic BP was observed significantly less in Group 3 patients taking ARB in the morning (3 patients) compared to other groups (12 patients) in each group, [P = .025]. Similarly, dipping pattern in diastolic BP was observed significantly less in Group 3 patients (4 patients) compared to others (13 patients) in Group 1 and 15 patients in Group 2 and Group 4, [P = .008]. Nondipping pattern was significantly associated with taking ARB in the morning, even when adjusted by age, sex, and other comorbidities. Conclusion: Fixed dose triple antihypertensive drug combinations enable good BP control regardless of the timing of drug while ARB-based ones may be taken in the evening to ensure dipping physiology.

Background: Previous studies have shown that depression and anxiety were independent risk factors for hypertension. Non-dipper hypertension is associated with higher cardiovascular mortality. The aim of this study was to evaluate the anxiety and depression scores in patients with dipper and non-dipper hypertension. Methods: The study sample consisted of 153 hypertensive patients. All patients underwent 24-h blood pressure monitoring. Patients were classified into two groups according to their dipper or non-dipper hypertension status. We evaluated results of the Hospital Anxiety and Depression Scale between groups. Results: Seventy-eight patients (38 male, mean age: 51.6 ± 12.5 years) had dipper hypertension while 75 patients (27 male, mean age: 55.4 ± 14.1 years) had non-dipper hypertension ( p = 0.141, 0.072, respectively). Clinical characteristics were similar for both groups. Patients with non-dipper hypertension had significantly higher depression and anxiety scores compared to patients with dipper hypertension. Dipper and non-dipper status significantly correlated with anxiety ( p: 0.025, r: 0.181) and depression score ( p: 0.001, r: 0.255). In univariate analysis, smoking, alcohol usage, presence of diabetes, hyperlipidemia, anxiety score >8 and depression score >7 were predictors of dipper versus non-dipper status. In multivariate logistic regression analyses only depression score >7 was independent predictor of dipper versus non-dipper status (odds ratio: 2.74, confidence intervals: 1.41-5.37). A depression score of 7 or higher predicted non-dipper status with a sensitivity of 62.7% and specificity of 62.8%. Conclusion: Non-dipper patients have significantly higher anxiety and depression scores compared to dipper patients. Evaluation of anxiety and depression in patients with hypertension might help to detect non-dipper group and hence guide for better management. [ABSTRACT FROM AUTHOR]

Background: Coronary slow flow may not only affect the coronary arteries, but it may also be a vascular problem affecting the rest of the arterial system., Objective: The aim of this study was to determine peripheral arterial stiffness and the thickness of the choroid layer in patients with slow coronary flow., Methods: Fifty consecutive patients (age, 54.3 ± 11.4 years, 38 male) with coronary slow flow and 25 consecutive patients (age, 50.5 ± 9.9 years, 16 male) with normal coronary arteries both documented by coronary angiography were included. Arterial stiffness parameters were measured noninvasively using a Mobil-O-Graph arteriography system. The choroidal thickness was assessed using the enhanced depth imaging optical coherence tomography method., Results: The patients with coronary slow flow had significantly higher peripheral systolic blood pressure, peripheral pulse pressure, central pulse pressure, and pulse wave velocity (PWV) and significantly thinner choroidal thickness compared to the controls. Thrombolysis in myocardial infarction frame count was positively correlated with PWV (r: 0.237, p = 0.041) and negatively correlated with choroidal thickness (r: -0.249, p = 0.031). There was also a negative correlation between PWV and mean choroidal thickness (r: -0.565, p < 0.001). Linear regression analysis showed that coronary slow flow was an independent predictor of both PWV and choroidal thickness when adjusted by age and sex., Conclusions: The acceleration of average peripheral arterial PWV with a thinning of choroidal thickness in patients with coronary slow flow may support the idea that this phenomenon may be a coronary presentation of a systemic microvascular disorder., Competing Interests: All the authors declare no conflict of interest.
