Key result
High-intensity resistance training in post-MI/PCI patients produced a mean maximum rate-pressure product of 17,369, significantly below the safety threshold of 36,000 (P < 0.001).
Why the study?
To investigate the maximum rate-pressure product using continuous blood pressure monitoring during high-intensity resistance training in cardiac rehabilitation participants after myocardial infarction, percutaneous coronary intervention, or both.
Does high-intensity resistance training maintain rate-pressure products below established safety thresholds in phase 2 cardiac rehabilitation patients after MI or PCI?
Observational (n=34)

High-intensity resistance training appears hemodynamically safe for phase 2 cardiac rehabilitation patients post-MI/PCI, as maximum rate-pressure products remain well below established safety thresholds.
High-intensity resistance training appears safe post-MI/PCI; extends RCT evidence supporting its role in cardiac rehabilitation.
The purpose of this study was to investigate the maximum rate-pressure product of cardiac rehabilitation participants after myocardial infarction, percutaneous coronary intervention, or both during high-intensity resistance training (HI-RT) using continuous blood pressure monitoring. Thirty-four individuals exercised on the leg press machine while being monitored with a continuous blood pressure monitor. The maximum rate-pressure product was significantly lower than the established safety threshold of 36,000 (P < 0.001), with a mean of 17,369 and standard deviation of 6634. Only 2% of observations had a value ≥36,000. These results suggest that cardiac rehabilitation patients can perform HI-RT while keeping their rate-pressure products under the safety threshold of 36,000 after myocardial infarction/percutaneous coronary intervention. Performance of HI-RT exercises contributes to return to precardiac event occupations, and continuous blood pressure monitoring may be an effective tool in evaluating the safety of HI-RT in this patient population.

Brown et al. (2020) conducted an observational in Myocardial infarction or percutaneous coronary intervention (n=34). High-intensity resistance training (HI-RT) vs. Established safety threshold of 36,000 was evaluated on Maximum rate-pressure product (p=<0.001). High-intensity resistance training in post-MI/PCI patients produced a mean maximum rate-pressure product of 17,369, significantly below the safety threshold of 36,000 (P < 0.001).
