Y52: Agents primarily affecting the cardiovascular system

Y52.0: Cardiac-stimulant glycosides and drugs of similar action

Cardiac-stimulant glycosides and drugs of similar action are substances that influence the function of the heart and the cardiovascular system. Often used in the treatment of cardiac disorders, these drugs work by increasing the force of the heart's contraction and slowing the rate of the heart's beat, improving blood flow and reducing symptoms like shortness of breath and fatigue associated with heart conditions. However, adverse reactions to these medications can occur which include nausea, loss of appetite, confusion, vision changes, and irregular heart rhythms. In particular, arrhythmias (abnormal heart rhythms) pose a considerable risk since they can lead to more serious heart conditions or even cardiac arrest. It is important to monitor the intake of these drugs consistently to manage these potential reactions.
