Insights
Changes in pulse pressure (PP) during hospitalization after percutaneous coronary intervention (PCI) show a U-shaped association with cardiovascular outcomes. Careful blood pressure management is crucial for patients post-PCI.
Area of Science:
- Cardiology
- Vascular Medicine
- Clinical Outcomes Research
Background:
- Limited data exist on the prognostic value of pulse pressure (PP) changes during hospitalization for patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI).
- Understanding these changes is crucial for optimizing patient care and predicting cardiovascular events post-PCI.
Purpose of the Study:
- To examine the association between discharge pulse pressure (PP) and cardiovascular outcomes in patients who underwent PCI.
- To investigate the prognostic value of PP changes during hospitalization in this patient cohort.
Main Methods:
- A retrospective study of 8,708 patients who underwent PCI was conducted using the Clinical Deep Data Accumulation System (CLIDAS).
- Pulse pressure (PP) was measured before PCI and at discharge, with patients categorized into quintiles based on PP change.
- Major adverse cardiac or cerebrovascular events (MACCE), revascularization, and heart failure (HF) hospitalization were analyzed in relation to PP and its changes.
Main Results:
- A U-shaped relationship was observed between PP changes and the incidence of MACCE, revascularization, and HF hospitalization.
- Higher discharge PP was associated with an increased risk of MACCE (adjusted hazard ratio 1.41 in the highest quintile).
- Both significant decreases (Q1) and increases (Q5) in PP were linked to higher MACCE risk, indicating a U-shaped association.
Conclusions:
- The study demonstrates a significant U-shaped association between pulse pressure (PP) changes during hospitalization and cardiovascular outcomes in patients post-PCI.
- These findings highlight the importance of monitoring and managing blood pressure, specifically PP, during hospitalization for patients undergoing PCI to improve clinical outcomes.
Background:
Limited data exist on the prognostic value of changes in pulse pressure (PP, the difference between systolic and diastolic blood pressure) during hospitalization for patients with coronary artery disease who have undergone percutaneous coronary intervention (PCI).
Methods:
In the Clinical Deep Data Accumulation System (CLIDAS), we studied 8,708 patients who underwent PCI. We aimed to examine the association between discharge PP and cardiovascular outcomes. PP was measured before PCI and at discharge. Patients were divided into five groups (quintiles) based on the change in PPQ1 (-18.0 ± 9.9 mmHg), Q2 (-3.8 ± 2.6), Q3 (reference; 3.7 ± 2.0), Q4 (11.3 ± 2.6), and Q5 (27.5 ± 11.2). We then analyzed the relationship between PP change and outcomes.
Results:
The mean patient age was 70 ± 11 years, with 6,851 (78 %) men and 3,786 (43 %) having acute coronary syndrome. U-shaped relationships were observed for the incidence rates of major adverse cardiac or cerebrovascular events (MACCE, a composite endpoint of cardiovascular death, myocardial infarction, and stroke), revascularization, and hospitalization for heart failure (HF). After adjusting for confounding factors, higher PP at discharge was associated with an increased risk of MACCE (adjusted hazard ratio 1.41; 95 %CI, 1.06-1.87 in Q5 [73.9 ± 9.3 mmHg]). Evaluating PP change revealed a U-shaped association with MACCE (1.50; 1.11-2.02 in Q1 and 1.47; 0.98-2.20 in Q5). Additionally, Q5 had a higher risk for hospitalization for HF (1.37; 1.00-1.88).
Conclusions:
Our findings demonstrate a U-shaped association between changes in PP and cardiovascular outcomes. This data suggests the significance of blood pressure control during hospitalization for patients who have undergone PCI.
