负荷试验对诊断冠心病及判断其程度是很有价值的。1971年 Rochimis 等调查了73个医疗中心,指出负荷试验的死亡率为0.01%,发生心律失常与持续胸痛需住院者为0.04%。Stuart 等调查1400个医疗中心发现死亡率为0.005%,心律失常为4.78/10,000;心肌梗塞发生率为3.6/10,000;总并发症发生率为8.86/10,000,对并发症危险性的了解和采取必要的防护,可以说负荷试验是安全的方法。
Load test for the diagnosis of coronary heart disease and determine the extent of its very valuable. In 1971, Rochimis et al investigated 73 medical centers and pointed out that the mortality rate of stress test was 0.01%, arrhythmia and persistent hospital stay of 0.04% were required. Stuart et al. Investigated 1,400 medical centers and found a mortality rate of 0.005%, an arrhythmia of 4.78 / 10,000; a myocardial infarction rate of 3.6 / 10,000; and a total complication rate of 8.86 / 10,000, understanding and taking necessary risk of complications Protection, it can be said that the load test is a safe method.
