Case 2

The vasodilator and diuretic agents worked to reduce the right and left ventricular___________

Summary Introduction

To review:

The work of vasodilators and diuretics in the given case.


Vasodilators are the agents that help blood vessels to dilate or open. They affect the muscles present in the walls of arteries and veins and prevent them from narrowing so blood can flow easily. Furthermroe, these vasodilators are prescribed to the patients suffering from hypertension.

Please refer to Clinical Application Case-2 for further information.


Ventricular afterload is defined as the force with which the ventricles must work to pump blood during a systole. Vasodilators decrease elevated blood pressure by reducing the left ventricular afterload, which caused an elevated BP, while diuretics help in fluid secretion, thus decreasing the right ventricular afterload. Vasodilators and diuretics work to reduce the right and left ventricular afterloads, respectively.
