Whole blood and plasma viscosity were measured of 90 patients with chronic cerebrovascular disease (CVD) and 56 healthy individuals by Couette rotational viscometer Contraves Low Shear 30 at a steady flow. Plasma viscosity was measured with capillary viscometer of Ubbelohde type. Two subgroups of patients were investigated: 23 patients with transient ischemic attacks (TIAs) and 67 patients with chronic cerebral infarctions (CCI). They were compared with two control groups: 56 healthy individuals without risk factors for stroke and 37 randomly selected subjects with risk factors for stroke. It is established significant elevation of plasma viscosity in the patients with cerebral ischemia. The elevation of blood viscosity was most pronounced at shear rate of 94.5 s(-1). This comparison is confirmed by the criterion, using blood rigidity number h defined by the formula of Whittington and Harkness. Conclusion is drawn from our study that chronic ischemic cerebrovascular disorders are characterized with chronic hyperviscosity.

Background And Purpose: Numerous studies have demonstrated the effectiveness of Chinese medicine injections (CMIs) in treating diabetic lower extremity arterial disease (Dia-LEAD). However, with the variety of CMIs available, it has become challenging to determine the optimal choice for Dia-LEAD patients. This study aims to compare and rank the efficacy of CMIs for Dia-LEAD to provide references and evidence for clinicians in optimising drug selection.

Background: We aimed to contribute to the literature by exploring the possible relationship of PV with erectile dysfunction (ED), as in atherosclerosis-based vascular diseases.
Methods: Between October 2021 and December 2022, 99 patients who applied to the urology polyclinic with a complaint of ED were included in the study (Group 1). Fifty-two patients who applied with a complaint other than ED constituted the control group (Group 2).

Background: Therapeutic plasma exchange (TPE) is the primary intervention for treating symptomatic hyperviscosity from hypergammaglobulinemia, yet its efficacy for treating hyperviscosity related to hyperfibrinogenemia is unclear.
Objective: Define the safety and efficacy of TPE for critically ill COVID-19 patients with elevated blood viscosity from hyperfibrinogenemia.
Method: A prospective, randomized controlled trial in critically ill COVID-19 patients at a single US healthcare system.

Objective: This study aims to explore the effects of high-intensity interval training (HIIT) on plasma volume (PV) variations in obese women, with a focus on understanding how menopausal status and age influence these changes.
Methods: We enrolled fifty-nine obese women (perimenopausal and postmenopausal), aged approximately 56.6 years in a six-week HIIT program.
