BACKGROUND Although transradial access (TRA) is being increasingly used in interventional cardiology, there are concerns about a possible increase in radiation exposure (RE) as compared to transfemoral access (TFA). METHODS In this retrospective study, we aimed to compare RE during coronary angiography and percutaneous coronary intervention (PCI)(More)
BACKGROUND It is not clear if the downward trend in cardiovascular disease (CVD) observed for ages up to 85 years can be extended to the oldest old, those 85 years and above. METHODS AND FINDINGS This nationwide cohort study presents age specific trends of CVD as well as for myocardial infarction (MI) and stroke separately for the period 1994 to 2010 for(More)
BACKGROUND Life expectancy and time to first hospitalization have been prolonged, indicating that people live longer without needing hospital care. Life expectancy increased partially due to improved survival from severe diseases, which, however, could lead to a more fragile population. If so, time to a subsequent hospitalization could decrease.(More)
It is often taken for granted that an ageing population will lead to an increased burden for the health care sector. However, for several diseases of big public health impact the rates have actually come down for a substantial period of time. In this study we investigate how much the incidence rates for myocardial infarction (MI), stroke, and cancer will(More)
This paper investigates the relationship between early life biological and social factors, partnership history, and mortality risk. Mortality risks for Swedish men and women over age 50 in the Uppsala Birth Cohort born 1915-1929 were estimated using survival analysis. Relative mortality risk was evaluated through nested multiplicative Gompertz models for(More)
BACKGROUND Marital status, income, and education might influence the risk of esophageal and gastric cancer, but the literature is limited. A large study addressing subtypes of these tumors was used to clarify these associations. METHODS A nationwide, Swedish population-based cohort study from 1991 to 2010 included individuals who were 50 years old or(More)
OBJECTIVES To examine whether the first admission to hospital after the age of 60 has been postponed to higher ages for men and women in Sweden, in line with the shift in mortality. DESIGN This nationwide observational study was based on data obtained from national registries in Sweden. The study cohort was created by linking the Register of the Total(More)
