AbstractBecause of concerns about the high risk of perioperative complications, the feasibility of minimally invasive aortic valve replacement (MIAVR) for elderly patients remains controversial. Here, we review our results of MIAVR in octogenarians with aortic valve stenosis (AS). Between October 2012 and December 2017, 110 patients with AS underwent MIAVR via a right anterolateral mini-thoracotomy; 41 patients were octogenarian (Group O). The perioperative outcomes of these patients were compared with those of the 69 patients who were less than 80  years of age (Group Y). A preoperative contrast-enhanced computed tom...

ConclusionsRiociguat treatment was associated with increased RV stroke volume index and trends for improvement in myocardial remodelling in patients with CTEPH. A larger clinical study is warranted to observe the therapeutic benefits of riociguat on RV remodelling.RésuméContexteLes effets du traitement par le riociguat sur le métabolisme, la perfusion et le débit du ventricule droit (VD) chez les patients atteints d’hypertension pulmonaire thromboembolique chronique (HPTC) sont inconnus. Dans la présente étude, nous analysons les changements aux ventriculaires droits associ&e...

Conclusions Riociguat treatment was associated with increased RVSVI and trends for improvement in myocardial remodeling in CTEPH patients. A larger clinical study is warranted to observe the therapeutic benefits of riociguat on RV remodeling. Teaser Riociguat is an approved medical treatment for chronic thromboembolic pulmonary hypertension (CTEPH) patients. We studied the effects of riociguat treatment on right ventricular (RV) remodeling by means of magnetic resonance imaging (MRI) and positron emission tomography (PET). After 6 months of riociguat treatment in 6 CTEPH patients, RV function increased, fibrosis decreased ...

Sema3E/PlexinD1 inhibition is a therapeutic strategy for improving cerebral perfusion and restoring functional loss after stroke in aged rats. Neurobiol Aging. 2018 Jun 11;70:102-116 Authors: Zhou YF, Li PC, Wu JH, Haslam JA, Mao L, Xia YP, He QW, Wang XX, Lei H, Lan XL, Miao QR, Yue ZY, Li YN, Hu B Abstract Brain tissue survival and functional recovery after ischemic stroke greatly depend on cerebral vessel perfusion and functional collateral circulation in the ischemic area. Semaphorin 3E (Sema3E), one of the class 3 secreted semaphorins, has been demonstrated to be a critical regulator in embr...

This study indicates that frailty and other age-related diseases could be prevented and significantly reduced in older adults. Getting our heart risk factors under control could lead to much healthier old ages. Unfortunately, the current obesity epidemic is moving the older population in the wrong direction, however our study underlines how even small reductions in risk are worthwhile." The study analysed data from more than 421,000 people aged 60-69 in both GP medical records and in the UK Biobank research study. Participants were followed up over ten years. The researchers analysed six factors that could impa...
