BACKGROUND/PURPOSE: Appropriate patient selection for mechanical circulatory support following percutaneous coronary intervention (PCI) remains a challenge. This study aims to evaluate the role of coronary perfusion pressure and other left ventricular hemodynamics to predict cardiovascular collapse following PCI.
CONCLUSIONS: In hemodynamically stable patients presenting with ACS, LVEDP and coronary perfusion pressure are not predictive of in-hospital cardiovascular collapse.

METHODS/MATERIALS: We retrospectively analyzed all patients who underwent PCI for acute coronary syndrome (ACS) from 2003 to 2016. Coronary perfusion pressure was calculated for each patient and defined as the difference in mean arterial pressure and left ventricular end diastolic pressure (LVEDP). Logistic regression analysis was performed to determine predictor of composite outcome of in-hospital mortality, myocardial infarction (MI), congestive heart failure (CHF), and cardiogenic shock.
RESULTS: Nine hundred twenty-two patients were analyzed. Two-hundred twenty-eight (25%) presented with ST-elevation MI (STEMI) while 694 (75%) underwent PCI for unstable angina or non-Q-wave MI. The mean LVEDP was significantly higher in the STEMI patients (24+/-9 vs. 19+/-8mmHg, p<0.05) and perfusion pressure significantly lower (68+/-24 vs. 74+/-18mmHg, p<0.05). Eighty-seven (9.4%) reached the composite endpoint, and there was no difference between the STEMI and Not-STEMI groups. Neither LVEDP nor coronary perfusion pressure was a predictor of the composite outcome following multivariable logistic regression analysis for either STEMI or Not-STEMI patients. Increasing age, chronic renal insufficiency (CRI), CHF, and low left ventricular ejection fraction were predictors of the composite outcome for Not-STEMI patients, whereas only history of cerebrovascular accident and CRI were predictors for STEMI patients.
SUMMARY: The authors retrospectively analyzed 922 patients from a single center who underwent percutaneous coronary intervention (PCI) for acute coronary syndromes to evaluate the role of coronary perfusion pressure and other left ventricular hemodynamics to predict cardiovascular collapse following PCI. They found that neither coronary perfusion pressure nor left ventricular end diastolic pressure was predictive of in-hospital cardiovascular collapse.
