| Abstract | Background Collateral coronary flow may protect patients against myocardial ischemia. There is no data regarding the difference in collateral development in relationship to coronary dominance and potential influence on outcome. We aimed to investigate whether there is a relationship between coronary dominance, collateral development and influence on outcome. Methods The study population comprised all patients with single vessel disease and right or left coronary dominance (RD or LD), with a proximal stenosis above 90%. Demographic, clinical and angiographic data were compared in patients with RD and LD, as well as outcome. Results More patients with ST elevation myocardial infarction (STEMI) and RD demonstrated collaterals compared to LD (51% vs. 26%, p = 0.042) and had a higher Rentrop score (1.5 ± 0.6 vs. 1.0 ± 0, p < 0.05). Fewer patients died in the RD group (9% vs. 26% in the LD group, p = 0.018). In patients without STEMI, there was a tendency to more collateral development in the RD group (although this difference became significant in patients with totally occluded vessels 80% in RD vs. 57% in LD, p < 0.05). In addition, in this group of patients without STEMI, (as in the STEMI group), there were fewer deaths in the RD group over the study period (6% vs 18% in the LD group, p < 0.01). Conclusions Patients with single vessel disease and RD develop more collaterals than those with LD, and have a better outcome. In addition, in individuals with STEMI and single vessel disease with collaterals, those with RD have a higher Rentrop score. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
