Why the study?
Several shortcomings of the American Heart Association Life's Simple 7 (LS7) metrics have been identified, prompting the development of a revised set of metrics whose national trends and associations with mortality needed evaluation.
Do revised Life's Simple 7 metrics improve the prediction of all-cause, cancer, and cardiovascular mortality compared to the original AHA metrics in US adults?
Do revised Life's Simple 7 metrics improve the prediction of all-cause, cancer, and cardiovascular mortality compared to the original AHA metrics in US adults?
A revised Life's Simple 7 metric incorporating modified criteria for weight, blood pressure, and diet provides stronger prognostic information for cancer mortality than the original AHA metrics.
No takes yet. Share an insight, caveat, or question.
Revised LS7 scores were associated with lower mortality; leaves open whether they improve prediction over original AHA metrics.
