| Abstract | For the estimation of left ventricular (LV) contractility, the fully noninvasive measurement of the maximum elastance (E/sub max/) from the steady-state single loop of end systolic pressure volume relation (ESPVR) is attempted. For 32 patients with coronary artery disease, we performed the gated myocardial SPECT with the simultaneous measurement of radial artery pressure using automated tonometer. The left ventricular volume generated from quantitative gated SPECT (QGS) program of SPECT and the central aortic pressure transferred from radial artery pressure measured by automated tonometer were used to make a pressure-volume (PV) loop. With a single PV loop, E/sub max/, was calculated using (1) single PV loop estimation method based on the consistency of normalized elastance curve and (2) regression method based on time-linearity of elastance, respectively. The values of E/sub max/ by the first method were distributed within the range (2.3-5.3) and showed the independence on calculation trials and initial condition for iterative calculation. Normalized elastance curves were consistent for all patients. The E/sub max/ and V/sub 0/ for PV data from sequential gated SPECT acquisition showed the consistent value, respectively (r=0.91 for E/sub max/, r=0.99 for V/sub 0/). The values of E/sub max/ by the second method were within (0.7-5.1) and showed the linear relationship (E/sub max normalized/=2.15/spl times/E/sub max linear/+0.45, r=0.64, p<0.001) with E/sub max/ by the first method. Despite of the lack of comparison with multiple PV loop method, we found the clinical feasibility of this fully noninvasive E/sub max/, estimation method. Therefore, we concluded that E/sub max/ obtained by this methods could be useful for assessment of LV contractility. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
