The miniature components of an intra-aortic balloon pumping system (IABP) have been successfully developed in this laboratory and have been effectively tested both in vitro and in 32 in vivo experiments using small animals weighing 3.5--18 kg. It is reasonable to assume that IABP can be successfully employed for clinical use in infants and small children.
outcomes between ethnic groups in patients presenting with their first myocardial infarct (MI).Methods: New Zealand residents (20 years old) hospitalised with their first MI (2014)(2015)(2016)(2017), and who underwent coronary angiography, were identified from the All NZ Acute Coronary Syndrome Quality Improvement registry.Results: Of the 17,404 patients, European/other comprised 76% of the population, M aori 11.5%, Pacific 5.1%, Indian 4.3% and other Asian 2.9%. M aori and Pacific patients had a greater burden of cardiovascular risk factors, and were more likely to present with heart failure and advanced coronary disease. After adjustment for age-group and sex, M aori and Pacific had significantly higher all-cause mortality (HR 2.55, (95%CI 2.12-3.07) HR 2.98, (95%CI 2.34-3.81), compared with European/others. When adjusted for differences in clinical presentation, clinical history and cardiovascular risk factors the excess mortality risk for M aori and Pacific patients was significantly reduced, but a differential persisted (HR 1.77, (95%CI 1.44-2.19), HR 1.42, (95%CI 1.07-1.83)), which was not further reduced by adjustment for differences in treatment.
Conclusion:In NZ patients after their first MI there is a three-fold variation in 1-year mortality based on ethnicity. At least half of the inequity in outcomes for M aori, and threequarters for Pacific people, is associated with differences in potentially modifiable clinical factors.
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.
