Effect of age on mortality in coronary artery bypass surgery in New York, 1991-1992.

abstract：BACKGROUND:Adenosine cardiac stress is widely used as an alternative to exercise testing during myocardial perfusion imaging (MPI). Dyspnea often accompanies the adenosine stress test. Although known asthmatic patients are excluded from this test because of the danger of bronchospasm, there is incomplete information re...
