The　＂Life＇s　Essential　8＂　(LE8)　score　is　an　assessment　of　cardiovascular　health　recently　introduced　by　the　American　Heart　Association.　This　study　aimed　to　explore　the　correlation　of　the　total　LE8　score　and　its　individual　metrics　with　all-cause　and　cardiovascular　disease　(CVD)　mortality　in　patients　with　hypertension.　Data　from　10,556　hypertension　adults　were　retrieved　from　National　Health　and　Nutrition　Examination　Survey　(NHANES)　from　2005　to　2018.　After　a　median　follow-up　of　6.75　years,　patients　with　high　LE8　scores　(＞=　75　points)　showed　significantly　lower　mortality　rates　from　all　causes　and　CVD　(P　＜　0.001).　Cox　regression　analysis　indicated　that　high　LE8　scores　were　associated　with　a　40%　lower　risk　of　all-cause　[0.60(0.50-0.73)]　and　CVD　mortality　[0.60(0.43-0.83)]　compared　to　low　scores.　As　the　total　LE8　score　increased　linearly,　the　likelihood　of　all-cause　and　CVD　mortality　decreased,　with　a　potential　threshold　at　60　points.　Subgroup　analyses　revealed　that　diet,　sleep,　nicotine　exposure,　physical　activity,　and　blood　glucose　control　affected　both　types　of　mortality.　The　LE8　score　was　negatively　correlated　with　the　risks　of　all-cause　and　CVD　mortality　in　hypertensive　patients.　Life　interventions　and　management　of　physical　indicators　based　on　the　LE8　score　may　be　an　effective　way　to　improve　mortality　in　hypertensive　patients.
