The target heart rate for esophageal natives is not explicitly defined in the provided studies, but based on the most recent and highest quality study, the focus should be on minimizing perioperative cardiac events and postoperative tachycardia, as seen in the study by 1. To calculate the target heart rate, one can use the general formula of 50-85% of the maximum heart rate, which is typically determined by subtracting the individual's age from 220.
- For example, if you're 40 years old, your maximum heart rate would be 180 beats per minute (220-40=180).
- Your target heart rate zone would then be 90-153 beats per minute (50-85% of 180). However, it's essential to consider the specific context of esophageal surgery and the potential risks associated with it, as highlighted in the study by 2, which emphasizes the importance of enhanced recovery after surgery (ERAS) programs in improving short-term outcomes. The study by 3 also supports the use of standardized clinical pathways to reduce postoperative complications and improve outcomes. In the context of esophageal natives, it's crucial to prioritize minimizing perioperative cardiac events and postoperative tachycardia, as seen in the study by 1, which demonstrated the beneficial effects of metoprolol in reducing these complications. Therefore, the target heart rate for esophageal natives should be individualized and based on the specific clinical context, taking into account the potential risks and benefits of different heart rate zones, as recommended by 1 and 2.
