Exercise stress testing (EST) is commonly used to evaluate chest pain, with some labs using 85% of age-predicted maximum heart rate (APMHR) as an endpoint for EST. The APMHR is often calculated using the formula 220-age. However, the accuracy of this formula and 85% APMHR as an endpoint may be questioned. Moreover, failing to reach 85% APMHR (known as chronotropic insufficiency) may also indicate poor cardiovascular prognosis, but measurements, such as percentage heart rate reserve (%HRR), maximum rate pressure product (MRPP), and the maximum metabolic equivalent of tasks (METs) reached during EST may provide better prediction of cardiovascular outcomes than not reaching 85% of APMHR. There is a need to incorporate comprehensive measurements to improve the diagnostic and prognostic capabilities of EST.
运动应激试验（EST）常用于评估胸痛，一些实验室将年龄预测最大心率（APMHR）的85%作为EST的终点。APMHR通常使用公式220 - 年龄来计算。然而，该公式以及85% APMHR作为终点的准确性可能受到质疑。此外，未能达到85% APMHR（称为变时性功能不全）也可能表明心血管预后不良，但EST期间达到的心率储备百分比（%HRR）、最大心率血压乘积（MRPP）以及最大代谢当量（METs）等测量指标，可能比未达到APMHR的85%能更好地预测心血管结局。需要纳入综合测量指标以提高EST的诊断和预后能力。
