Patients who received a combination of ticagrelor plus aspirin within 24 hours of undergoing coronary artery bypass grafting (CABG) had significantly improved saphenous vein graft patency rates 1 year post-procedure compared with those who only received aspirin, according to findings of the DACAB* trial.

Light exercise may improve mortality in ageing females

14 Jan 2018

Light-intensity and moderate-to-vigorous (MV) physical activity (PA) improve mortality in elderly females, a recent study has shown.

Using hip-worn triaxial accelerometers, the researchers measured the usual PA of 6,382 community-dwelling elderly females (mean age 786 years). They found that females in the second (relative risk [RR], 0.73; 95 percent CI, 0.57–0.93) and third (RR, 0.56; 0.41–0.76; p<0.001 for trend) tertiles of PA had significantly lower all-cause mortality compared with those in the lowest tertile.

The trend remained the same even when selecting only the high light-intensity PA. Those in the second (RR, 0.61; 0.47–0.78) and third (RR, 0.57; 0.42–0.76; p<0.001 for trend) tertiles of high light-intensity PA had significantly reduced all-cause mortality.

Higher MVPA (RR, 0.66 for second tertile; 0.51–0.84; RR, 0.46 for third tertile; 0.33–0.65; p<0.001 for trend) was likewise associated with lower all-cause mortality.

Exercise also improved mortality from different causes. Increasing intensities of high light-intensity PA and MVPA correlated significantly with lower risks of cardiovascular risk mortality (p<0.001 and p=0.005 for trend, respectively). All analyses were adjusted for accelerometer wear time and demographic variables, among others.

“The mortality benefit of light-intensity PA and MVPA appears to extend to all subgroups examined—obese, aged 80 [years] and older, with multimorbidity, and with low physical function,” researchers said, emphasizing the importance of PA in ageing females.
