A randomized controlled clinical trial of prolonged balloon inflation during stent deployment strategy in primary percutaneous coronary intervention for ST-segment elevation myocardial infarction: a pilot study

Table 3 Cardiac magnetic resonance (CMR) data

Endpoint	PBSG (n = 30)	CDSG (n = 20)	P value
Infarct size (%LVM)	12.1 (4.5)	13.4 (3.9)	0.512
Presence of MVO-no. (%)	2/30 (6.7)	10/20 (50)	0.023
Presence of IMH-no. (%)	6/30 (20)	8/20 (25)	0.378
Myocardial salvage index	60.5 (22.1)	56.4 (20.1)	0.081
LVEF (%)	50.2 (7.5)	42.1 (6.3)	0.026

%LVM percentage of LV mass, MVO microvascular obstruction, IMH intramyocardial hemorrhage, LVEF left ventricular ejection fraction (The LVEF was calculated by subtracting the volume at end systole from the volume at end diastole and dividing the result by the volume at end diastole)
