Prognostic Value of Left Ventricular End-Diastolic Pressure in Patients With Non-ST-Segment Elevation Myocardial Infarction

Tables

Table 1. Demographic, Hemodynamic and Laboratory Characteristics
 
LVEDP > 22 mm Hg (n = 109)LVEDP ≤ 22 mm Hg (n = 258)P value
Data are expressed as a number (percent) or median (interquartile range). LVEDP: left ventricular end-diastolic pressure; PCI: percutaneous coronary intervention; CABG: coronary artery bypass grafting; TIMI: thrombolysis in myocardial infarction; eGFR: estimated glomerular filtration rate. *Chronic kidney disease was defined as eGFR < 60 mL/min/1.73 m2.
