This study is looking at a new device called QuantaFlo HD. It measures blood flow in your finger during a forced breath to assess how well your heart and blood vessels are working (cardiovascular function). Researchers want to see if the QuantaFlo HD test results match up with a different heart test called an echocardiogram (Echo). You might be able to join if you are an adult (22 years or older) with a history of heart disease, peripheral artery disease (PAD), or at least two conditions like high blood pressure (hypertension), diabetes, or high cholesterol (hyperlipidemia). The study aims to enroll 600 people, but its current status is unclear.
