Implantation of a pacemaker is an expensive procedure and about one in three patients does not benefit from it. Therefore, it is important for doctors to know whom of the patients the pacemaker will (or will not) help.

Doctors at the Tyumen Cardiology Research Center set a goal to identify the signs by which candidates for implantation should be selected. They have created a special formula which one can use to predict how a particular patient would respond to a pacemaker installation. In order to work out the formula the researchers took into account sex, age, duration of the disease, data on the excitation of the ventricles (the more time it takes to excite the ventricles, the worse the course of the disease and the higher the mortality rate) and the delay of the discharge of blood from the aorta.

The scientists also took into account the level of natriuretic brain hormone that is released in response to the stimulation of the heart muscle cells; it is a recognized marker of the severity of chronic heart failure.

20,285 doctors and scientists from 35 countries participated in the congress in 2017, the press service of the Tomsk Research Medical Center reports.
