Study: Texas Tech's CHAMP-HF pilot examining metabolic risk and nonischemic heart failure in Hispanic participants. 12
Design and measurements: This observational project proposed comparing Mexican American and non-Hispanic White patients with heart failure. Its question concerned the relationship between metabolic-syndrome risk factors and left-ventricular structure and function, including adjustment for blood pressure and coronary disease. 12
What is established: The inspected record is withdrawn, with an April 2015 update; no analyzed cohort or outcome estimate was verified. Its stated hypothesis is not proof of a biological or ethnic difference in cardiac function. This specific Texas Tech protocol must also be distinguished from other, larger heart-failure projects using the same CHAMP-HF acronym. 12
