Study of some components of the influence and formation of blood flow in patients with "slow flow".

Background: "Slow flow" is one very important concept in modern fundamental and clinical biomedicine. Slow coronary flow is indicative of delayed filling of the terminal coronary artery vessels, occurring in the absence of significant coronary stenosis. This group patient of patients exhibits a high incidence of disability and represents a significant financial and material burden for the state and the healthcare system in general.

Study of blood rheological parameters and NO in coronary artery disease patients with and without collaterals.

Background: In coronary artery disease (CAD), an alternative way of improvement of blood circulation in the ischemic area of the myocardium is coronary collateral circulation. Our study aimed to investigate the rheological parameters of blood and nitric oxide (NO) content in patients with various degrees of collateral development and the likelihood of the influence of blood fluidity on collateral angiogenesis.

Methods: We studied patients with stable CAD who underwent elective coronary angiography and a control group with the same mean age.
