Why the study?
Do age, sex, and ischaemic heart disease predict survival in patients undergoing long-term cardiac pacing?
Do age, sex, and ischaemic heart disease predict survival in patients undergoing long-term cardiac pacing?
Age, sex, and the presence of ischemic heart disease are strong prognostic indicators for survival after pacemaker implantation, which can help clinicians match generator lifetimes to patient life expectancy.
Answers are grounded in this paper and cite their sources.
Age, sex and ischaemic heart disease were associated with survival after pacing; hypothesis-generating for matching generator life to patient expectancy.
The influence of age, sex, and overt ischaemic heart disease on survival after pacing was studied in a population of 427 patients. The median survival for the whole group was 7.75 years. Women between 55 and 74 years and men between 65 and 74 years enjoyed median survivals in excess of 10 years. Patients over 74 years and men with ischaemic heart disease had median survivals of the order of 5 years and 3 1/2 years, respectively. The findings may help to match generator lifetimes to patient-survival prospects.
