A pharmacological stress take a look at using adenosine or regadenoson (Lexiscan) is a diagnostic process employed to evaluate blood stream to the guts muscle. This take a look at is usually carried out on people who’re unable to bear a standard train stress take a look at attributable to bodily limitations or different medical circumstances. The medicine, both adenosine or regadenoson, mimics the results of train by dilating the coronary arteries, thereby growing blood stream to the guts. A radioactive tracer is injected, and imaging, usually a nuclear scan, is carried out to visualise the distribution of blood stream. Areas with decreased blood stream could point out the presence of coronary artery illness.

This permits for early detection and intervention, doubtlessly stopping extra critical cardiac occasions. Traditionally, pharmacological stress checks utilizing brokers like dipyridamole had been developed as alternate options to train stress testing. Adenosine and regadenoson are extra selective, and regadenoson (Lexiscan) affords a shorter period of motion and extra handy administration, enhancing affected person consolation and take a look at effectivity.
