Benefit of high cardiovascular health for incident cardiovascular events and mortality in elderly population


 
 
 There is consistent evidence of the association between ideal cardiovascular health and lower incident cardiovascular disease (CVD); however, most studies used a single measure of cardiovascular health.
 
 
 
 To examine the association of change in cardiovascular health with subsequent incident CVD and mortality in elderly population.
 
 
 
 In the Korea National Health Insurance Service-Senior (≥60 years) cohort, 312,736 participants who received national health check-ups between 2005–2012 were assessed for eligibility. Using the 7metrics of the American Heart Association (nonsmoking; and ideal levels of body mass index, physical activity, diet, blood pressure, fasting blood glucose, and total cholesterol), participants with 0 to 2, 3 to 4, and 5 to 7 ideal metrics were categorized as having low, moderate, and high cardiovascular health. Change in cardiovascular health over 2 years between 2005 and 2006 was considered.
 
 
 
 The study population included 162,149 participants without prior CVD or malignancy (median age at baseline, 69 [IQR 66–73] years; 91,408 [56.2%] women), of whom 59,887 had data about cardiovascular health change. Over a median follow-up of 5.8 (5.5–8.0) years, 5346 incident CVD events and 6035 death occurred. In multivariable analysis and compared with individuals with persistently low cardiovascular health (consistently low group, 7.9% of participants; CVD incident rate per 1000 person-years, 21.1 [95% CI, 19.4–23.0]), a lower CVD risk was observed in the consistently moderate group (38.7% of participants; absolute rate difference per 1000 person-years, −4.8 [95% CI, −5.5 to −4.1]; HR, 0.77 [95% CI, 0.70–0.85]), the moderate to high group (11.6% of participants; absolute rate difference per 1000 person-years, −7.7 [95% CI, −8.8 to −5.5]; HR, 0.62 [95% CI, 0.55–0.70]), the high to moderate group (11.2% of participants; absolute rate difference per 1000 person-years, −7.2 [95% CI, −8.3 to −5.9]; HR, 0.64 [95% CI, 0.56–0.72]), and the consistently high group (11.3% of participants; absolute rate difference per 1000 person-years, −10.2 [95% CI, −11.2 to −9.1]; HR, 0.51 [95% CI, 0.44–0.58]). A lower mortality risk was observed in the consistently moderate group, the moderate to high group, and the high to moderate or high groups.
 
 
 
 Among a group of elderly participants without CVD, there was benefit of moderate or high cardiovascular health for incident cardiovascular events and mortality.
