Summary

This study checks if a quick, non-invasive finger test (QuantaFlo HD) can detect early signs of heart dysfunction. Researchers will compare the finger test results with standard heart ultrasound measurements in 600 adults who have risk factors like high blood pressure or diabetes. The goal is to see if the finger test is accurate enough to be a simple screening tool for heart problems.
