What is it about?
• I was able to create a data analysis comparison/ tool called a Pressure-Flow (PF) loop. It takes two measurements, the blood pressure inside the heart and the speed of the blood flowing out, and combines them into a single visual chart in real time. • I have tested this method in a laboratory setting by giving a heart-stimulating drug (Dobutamine) to track exactly how the heart's energy transfer changes when it is forced to work harder and faster. • I was able to prove that the heart's peak contraction and the peak blood flow do not happen at the same moment. Instead, the main artery (the aorta) temporarily stores some of that energy like a spring before pushing the blood forward.

Why is it important?
Right now, doctors evaluate heart health by looking at blood pressure and blood volume separately. This paper argues that doing so is like judging a car's engine by looking only at its fuel level or its top speed, rather than how well it transfers engine power to the wheels a very simple analogy. • This approach provides a much more accurate picture of "heart efficiency" (hydraulic energy transfer). • In the future, this framework could be turned into medical software to help doctors precisely spot heart failure, check if an artificial heart valve is working correctly, or see if a patient needs heart surgery.
Perspectives
• I believe that this measurement & change prove that the new "Pressure-Flow loop" framework is a superior way to look at heart health compared to older methods. Other scientists might look at the exact same data but have a different perspective on how useful the tool actually is. I am developing this further for the right ventricle and comparing different drugs.
