The levels of interleukin 1beta, interleukin 6, and interleukin 10 were elevated in the serum of patients with dementia. No statistically significant correlation was recorded in the interleukin levels among patients with Alzheimer's disease and vascular dementia. Also, no significant correlation was observed in the interleukin levels in the serum and the severity of dementia. However, a significant correlation was found between IL-6 and tumor necrosis factor-alpha (TNF-alpha) levels and age. The levels of IL-1beta and IL-6 were positively correlated with hypertension, and IL-2 levels were negatively correlated. No correlation was found between depressive symptoms and levels of cytokines in the serum.

Over the past two decades, blood flow restriction training (BFRT) has gained popularity not only in athletic performance training, but also with many researchers and physical therapists as an innovative rehabilitation tool. Blood flow restriction (BFR) exercise is a novel exercise modality in clinical settings, which induces muscle hypertrophy and increases strength with low to moderate training intensity through increased anabolic processes mediated by BFR (usually with cuff inflation). BFR limits arterial and venous blood flow and leads to blood pooling, which could increase the effects of exercise-induced training. Strength training at lower intensities (20–40% of maximum strength) in combination with BFR showed similar effects on muscle hypertrophy as training at 70% strength level without BFR. In this context, considering that periods of immobilization (or reduced functionality) due to pathology, injury, or surgery cause harmful effects on muscle mass and strength in both young and old people, muscular adaptations of occlusion exercise could be beneficial to the elderly and post-operative patients in rehabilitation regarding muscle regeneration. Furthermore, as this type of exercise does not require high loads, it might be a feasible method in cardiac rehabilitation. Therefore, this chapter aims to review all recent literature regarding the impact of low-load BFR resistance training in patients with cardiovascular pathologies on muscle strength and hypertrophy, vascular function, safety, cardiovascular responses, and inflammatory markers.

Therapeutic exercise is integral to the comprehensive rehabilitation of patients with cardiovascular disease and, as such, is recommended by the American Heart Association as a valuable and effective treatment method for such patients. The type of exercise applied to these patients is aerobic and resistance exercise with mild intensities and loads to avoid overloading the cardiovascular system. Blood flow restriction exercise is a novel exercise modality in clinical settings that has in many studies a similar effect on muscle hypertrophy, strength, and cardiovascular response to training at a 70% strength level without blood flow restriction. Since this exercise mode does not require high-intensity loads, it can be a safe method for improving muscle strength, cardiovascular endurance, and functionality in cardiovascular patients. Given that, the objective of this review is to assess and summarize existing evidence for the use of blood flow restriction in cardiovascular patients. A scoping review of existing clinical trials was conducted. Eleven studies were examined that suggested the use of blood flow restrictions in cardiovascular patients to achieve improvements in muscle strength, functionality, and cardiovascular parameters such as blood pressure decrease.
