Patient was educated on venous vasodilators and its mechanism of action as follows:
- Constricted or collapsed veins offer less capacitance, which increases the blood return to the heart.
- This can be detrimental in individuals with heart failure, as the heart is already in failure and cannot accommodate any extra load. This can worsen the condition of the heart.
- This situation can be helped with venous vasodilators, as 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.
- Reduced effort will lead to reduced workload and reduced oxygen demand by the heart muscle.
- This can help an individual with angina or cardiac failure, yet maintaining an optimal pumping activity of the heart.
