U-shaped association of central pulse pressure with long-term prognosis after ST-segment elevation myocardial infarction

The relationship between central pulse pressure (CPP) measured at the time of primary percutaneous coronary intervention (PPCI) and long-term prognosis after ST-segment elevation myocardial infarction (STEMI) has not been investigated. CPP measurements were performed in 1348 patients with STEMI (327 women; mean age 62.5 ± 12.1 years) undergoing PPCI. Aortic systolic and diastolic blood pressure was measured before intervention. The primary outcome was 8-year all-cause mortality. The median [25–75th percentile] CPP value was 55.0 [43.0–70.0] mmHg. CPP correlated negatively with heart rate (P
