Coronary artery calcium associated with prevalence of diastolic dysfunction: BMC

Of the individuals in the population, 7995 had CAC = 0, 4661 had 0 < CAC < 100, and 2537 had CAC > 100. Those with CAC = 0 had considerably lower prevalence ratios for definite and definite or probable DD than those with CAC = 100. The linear relationship between CAC and E/e′ was significant.

The adjusted HRs with 95% CI for mortality of CAC ≥100 without definite DD, CAC <100 with definite DD, and CAC ≥100 with definite DD were 2.56, 3.08, and 3.91, respectively, in comparison to CAC <100 without definite DD. Significant CAC was substantially linked to quicker development in definite DD over time, with a faster elevation of E/e′ during follow-up among subjects with at least two echocardiographic measures who did not have DD at the time of CAC assessment.

Overall, there was a significant correlation between CAC and DD in a general population that had a thorough health screening examination that included both a CAC scan and echocardiography at the same time. The risk of mortality was higher for patients with both subclinical measures than for those with only one.
