İnönü Üniversitesi Tıp Fakültesi Turgut Özal Tıp Merkezi, Ortopedi ve Travmatoloji Anabilim Dalı, 44280 Malatya, Türkiye.
Objectives: In this study, we aimed to evaluate microvascular changes using nailfold capillaroscopy in patients who underwent digit replantation and revascularization.
Patients And Methods: A total of 46 patients (34 males, 12 females; mean age: 45.8±17.
The Relationship Between Blood Pressure and Heart Rate Response During Exercise Testing with Microcirculation Indices.
High Blood Press Cardiovasc Prev

First Department of Cardiology, School of Medicine, National and Kapodistrian University of Athens, Hippokration Hospital, Vas. Sofias 114, 11527, Athens, Greece.
Introduction: Hypertension is associated with changes in microcirculation, while increased blood pressure (BP) during exercise stress testing has been correlated with adverse outcomes.
Aim: To evaluate the relationship of microcirculation with exercise BP response in hypertensive individuals.
Methods: 105 hypertensive individuals underwent exercise stress testing and nail-fold videocapillaroscopy assessment, in order to evaluate the relationship of BP response to exercise with capillary density.
Nailfold videocapillaroscopy findings and associations with organ involvement in mixed connective tissue disease.

Service de Rhumatologie, Hôpital Cochin, AP-HP Centre Université Paris Cité, Paris, and INSERM U1016, Institut Cochin, CNRS UMR8104, Paris, France.
Objectives: To investigate nailfold videocapillaroscopy (NVC) abnormalities in mixed connective tissue disease (MCTD).
Methods: Patients with MCTD followed at the Rheumatology Department in Cochin Hospital (Paris, France) were identified based on individual record review. Diagnosis of MCTD required fulfillment of one of the three sets of classification criteria.
Blood flow dynamics in the arterial and venous parts of the capillary.

Although there is currently sufficient information on various parameters of capillary blood flow, including the average values of blood velocity, there is no data on the dynamics of velocity and the mechanisms of its modulation in various parts of the capillary. The main idea of this work is to develop a tool and image data processing to study the characteristics of the capillary blood flow dynamics. In this study, using the developed method of high-speed videocapillaroscopy, the red blood cells (RBC) velocities in the arterial and venous parts of the nailfold capillaries were compared and a time-frequency analysis of the dynamics of the velocity signals with the calculation of phase coherence was performed.

Department of Rheumatology, Affiliated Hospital of Nantong University, 20 Xisi Road, Jiangsu Province, Nantong, 226001, China.
Objectives: The clinical manifestations of dermatomyositis (DM) are diverse, nailfold video-capillaroscopy (NVC) can reflect microangiopathy, a process believed to contribute significantly to the clinical manifestations of DM. We aimed to explore the distinctive alterations and implications of nailfold capillary for evaluating disease progression in individuals with DM.
Methods: We gathered clinical data from 76 DM patients who underwent NVC in the Affiliated Hospital of Nantong University between September 2017 and September 2022.
