Study finds that the LS7 and LE8 scores predict all-cause and cardiovascular mortality with similar efficacy in the overall U.S. population. However, the PCE score is better at predicting mortality in individuals aged 40 to 79.
By Dr. Sanchari Sinha Dutta, Ph.D.May 5 2024 Scientists at the University of Alabama at Birmingham, USA, have conducted a study to compare the efficacy of Life’s Essential 8 scores and Life’s Simple 7 scores in predicting the risks of all-cause mortality and cardiovascular disease -related mortality in the general US population.Study: Association of Life’s Essential 8 and Simple 7 Scores With Mortality: Comparison With Pooled Cohort Equation.
In addition to these seven risk factors, sleep has been found to be significantly associated with cardiovascular disease and related mortality. Given the significance of sleep, the AHA has developed Life’s Essential 8 score, a new cardiovascular health metric that includes sleep as an additional component. The LE8 score also accounts for medication use.
Study design The study utilized the National Health and Nutrition Examination Survey data collected between 2007 and 2018. The NHANES recruits a nationally representative population to estimate population-level health and nutritional status in the US. Important observations The comparison between LS7 and LE8 scores was conducted on 21,721 individuals, representing approximately 157 million individuals in the US population.
During the average study follow-up period, the PCE-based model showed higher efficacy in predicting all-cause mortality and cardiovascular mortality in individuals aged 40 to 79, compared to LS7 and LE8 scores.
