Despite the increase in the number of cardiovascular diseases worldwide, the number of new drugs to treat these diseases has been decreasing in the last decade. Current preclinical drug evaluation strategies, which use cell cultures and oversimplified animal models, cannot meet the growing demand for new and effective drugs. In the last decade, the development of microfluidic bioreactors and organ-on-chip systems to improve the drug screening process has been increasing significantly. These systems have shown many advantages over previous preclinical models. Despite all these advantages, keeping the oxygen concentration at the optimal physiological level in microfluidic systems has its own... 

In the last decade, the application of organ-on-chip systems to investigate the effectiveness and side effects of various drugs, modele diseases for different tissues has become noticed a lot because these systems are a promising approach to eliminate animal tests and clinical studies on different people. Current conventional methods for drug testing are expensive, time-consuming, and sometimes unreliable. Various organ-on-a-chip systems have been fabricated in order to mimic the conditions of different native tissues in the human body, but only the blood vessel has been considered in most of them while besides blood vessels, as a source to nourish cells, there are lymph vessels as a sink in... 

Cardiovascular diseases are one of the leading causes of death worldwide. Despite significant advances in therapeutic interventions for these diseases, the pathophysiology remains incompletely understood. Challenges in drug evaluation include the lack of appropriate clinical trials, such as conventional 2D cell cultures and animal studies, as well as the absence of model systems that can provide complex and patient-specific cardiac functions for diagnosis. Organ-on-a-chip devices have the potential to mimic the body's response to treatments by utilizing microscale cell culture fluid connections and creating realistic models of human organs of interest. Our objective is to develop a...
