Cardiotonic effect
The cardiotonic effect, also known as positive inotropy, refers to the physiological action of increasing the force of myocardial contraction. This effect is crucial in treating conditions like heart failure, where the heart's pumping efficiency is compromised. Cardiotonic agents work through various mechanisms, including modulating intracellular calcium levels, to enhance cardiac output and improve circulatory function, ultimately leading to better tissue perfusion and reduced symptoms of cardiac insufficiency.
