Myocardial perfusion imaging with 99 mTc - tetrofosmin SPECT in breast cancer patients that received postoperative radiotherapy: a case-control study

Table 5 Multiple regression analysis in 46 female patients with breast cancer and 85 control females after myocardial perfusion imaging with T - SPECT).

Independent variable	SSS Beta	p	SRS Beta	p	ASSS Beta	p
Left BC versus controls	-0.26	0.0001**	-0.02	0.05*	-0.19	0.05*
Right BC versus controls	-0.21	0.045*	0.04	0.68	-0.06	0.59
Left BC versus Right BC	-0.09	0.54	-0.25	0.11	-0.21	0.17

Dependent variables: summed stress score (SSS); summed rest score (SRS); anterior wall stress score (ASSS)
The analysis was performed after controlling for hypertension, hyperlipidemia and family history of cardiovascular disease. BC: breast cancer patients; *: p ≤ 0.05; **: p ≤ 0.01.
