Cardiovagal Function Measured by the Deep Breathing Test: Relationships With Coronary Atherosclerosis.

ABSTRACT: Background The cardiovagal function can be assessed by quantification of respiratory sinus arrhythmia (RSA) during a deep breathing test. However, population studies of RSA and coronary atherosclerosis are lacking. This population-based study examined the relationship between RSA during deep breathing and coronary atherosclerosis, assessed by coronary artery calcium score (CACS). Methods and Results SCAPIS (Swedish Cardiopulmonary Bioimage Study) randomly invited men and women aged 50 to 64 years from the general population. CACS was obtained from computed tomography scanning, and deep breathing tests were performed in 4654 individuals. Expiration-inspiration differences (E-Is) of heart rates were calculated, and reduced RSA was defined as E-I in the lowest decile of the population. The re
