Aims

Although several studies have shown that the right ventricular to pulmonary artery (RV-PA) coupling, assessed by the ratio between tricuspid annular plane systolic excursion and systolic pulmonary artery pressure (TAPSE/sPAP) using echocardiography, is strongly associated with cardiovascular events, its prognostic value is not established in acute coronary syndrome (ACS). We aimed to assess the in-hospital prognostic value of TAPSE/sPAP among patients hospitalized for ACS in a retrospective analysis from the prospective ADDICT-ICCU study.

Methods and results

A total of 481 consecutive patients hospitalized in intensive cardiac care unit [mean age 65 ± 13 years, 73% of male, 46% ST-elevation myocardial infarction (STEMI)] for ACS [either STEMI or non-STEMI (NSTEMI)] with TAPSE/sPAP available were included in this prospective French multicentric study (39 centres). The primary outcome was in-hospital major adverse cardiovascular events (MACEs) defined as all-cause death, resuscitated cardiac arrest, or cardiogenic shock and occurred in 33 (7%) patients. Receiver operating characteristic curve analysis identified 0.55 mm/mmHg as the best TAPSE/sPAP cut-off to predict in-hospital MACEs. TAPSE/sPAP &lt;0.55 was associated with in-hospital MACEs, even after adjustment with comorbidities [odds ratio (OR): 19.1, 95% confidence interval (CI) 7.78–54.8], clinical severity including left ventricular ejection fraction (OR: 14.4, 95% CI 5.70–41.7), and propensity-matched population analysis (OR: 22.8, 95% CI 7.83–97.2, all P &lt; 0.001). After adjustment, TAPSE/sPAP &lt;0.55 showed the best improvement in model discrimination and reclassification above traditional prognosticators (C-statistic improvement: 0.16; global χ2 improvement: 52.8; likelihood ratio test P &lt; 0.001) with similar results for both STEMI and NSTEMI subgroups.

Conclusion

A low RV-PA coupling defined as TAPSE/sPAP ratio &lt;0.55 was independently associated with in-hospital MACEs and provided incremental prognostic value over traditional prognosticators in patients hospitalized for ACS.
