Objective We investigated the relationship between the right cardiac system and increased pulmonary artery systolic pressure (PASP) in the elderly.Patients and Methods Echocardiography stable state data were available for 163 of 200 consecutive autopsied patients. Of these, PASP could be estimated by extrapolation from the maximum pressure gradient in tricuspid valve regurgitation from echocardiograms in 73 cases; however, 22 cases with secondary changes attributable to left cardiac insufficiency had to be excluded. We studied the remaining 51 patients in detail (16 men, 35 women, age 68-103 years; mean, 87.7±8.1). We investigated the following: echocardiographic and pathologic variables, age, sex, body mass index, the survival time (from echocardiography to autopsy), and the presence or absence of chronic pulmonary disease.Results
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
