Patient was educated on mixed arterial and venous vasodilators as follows:
- Dilation of arteries results in decreased resistance for the heart, pumping blood into the arterial system. So, more amount of blood can be pumped by the heart with reduced effort. Reduced resistance in the arteries will lead to reduced blood pressure.
- Dilation of veins results in increased capacitance, where by, the veins can accommodate more blood volume. This reduces the blood return to the heart. The reduced volume of blood return to the heart can be pumped by the heart with reduced effort.
- These drugs by reducing the resistance offered by the arteries and increasing the capacitance of veins, contribute towards reducing the workload on the heart.
- These factors help an individual in cardiac failure to pump optimal amount of blood with reduced effort. Also, they help a heart function optimally at reduced blood and oxygen supply.
- So, mixed arterial and venous vasodilators can be used to manage individuals with hypertension, cardiac failure, and angina.
