Summary Although chronic infection with cytomegalovirus ( CMV ) is known to drive T lymphocytes toward a senescent phenotype, it remains controversial whether and how can cause coronary heart disease CHD ). To explore seropositivity or T‐cell populations associated immunosenescence were informative for adverse cardiovascular outcome in the very old, we prospectively analyzed peripheral blood samples from 751 octogenarians (38% males) Newcastle 85+ study their power predict survival during...

Abstract Background Comorbidity is common and has a substantial negative impact on the prognosis of patients with acute myocardial infarction (AMI). Whilst receipt guideline-indicated treatment for AMI associated improved prognosis, extent to which comorbidities influence provision its efficacy unknown. Therefore, we investigated association between survival seven comorbidities. Methods We used data 693,388 recorded in Myocardial Ischaemia National Audit Project (MINAP), 2003–2013. optimal...

Inherited genetic variation of mitochondrial DNA (mtDNA) could account for the missing heritability human longevity and healthy aging. Here, we show no robust association between common variants mtDNA frailty (an "unhealthy aging" phenotype) or mortality in 700, more than 85-year-old, participants Newcastle 85+ study. Conflicting data from different populations underscore our conclusion that there is currently compelling link inherited
