Association of Time in Target Range of Resting Heart Rate With Adverse Clinical Outcomes in Patients With Acute Coronary Syndromes After Percutaneous Coronary Intervention
Heart rate (HR) has been proved to be associated with major adverse cardiovascular events (MACE) in Acute coronary syndrome patients. However, the threshold value and clinical significance of time in target of resting heart rate (TTR-HR) remain insufficiently elucidated. Our study aimed to evaluate...

| Summary: | Heart rate (HR) has been proved to be associated with major adverse cardiovascular events (MACE) in Acute coronary syndrome patients. However, the threshold value and clinical significance of time in target of resting heart rate (TTR-HR) remain insufficiently elucidated. Our study aimed to evaluate the independent association between TTR-HR and cardiovascular outcomes in the follow-up study of ACS. A total of 1455 ACS patients who underwent percutaneous coronary intervention (PCI) and were admitted to 22 hospitals between 2019 and 2022 were enrolled and followed up for 12 months. MACE was defined as a composite of cardiac death, nonfatal recurrent myocardial infarction, ischemic-driven revascularization, and ischemic stroke. The association between TTR-HR and cardiovascular outcomes was assessed using Cox regression model. Compared to patients with TTR-HR 0–50% and >50%–75%, patients with TTR-HR > 75%–100% were older and less alcohol user, less likely to use diuretics and anti-diabetic drugs, these patients had less comorbidities of hyperlipidemia, diabetes, heart failure, and cardiac shock. After 12 months follow up, the incidence of MACE and composite endpoint but not mortality was higher in patients with TTR-HR 0–50% and >50%–75% than those with TTR-HR > 75%–100%. After multivariate adjustment, TTR-HR [hazard ratio = 2.11, 95% CI: 1.19–3.74, p = 0.01] was independently associated with composite endpoint. In summary, our study demonstrates that TTR-HR holds significant prognostic value, with TTR-HR > 75%–100% being independently associated with reduced composite endpoint risk in ACS patients following PCI. These findings emphasize the importance of effective heart rate control in ACS patients following PCI. |
