Tissue Doppler imaging measurements during the cooling trial

	Young		Older
Variable	Baseline	Cooling	Baseline	Cooling
ACC, cm/s2	132.45 ± 9.13	127.55 ± 10.65	137.81 ± 10.14	143.94 ± 9.36
Sm, cm/s	8.03 ± 0.39	7.91 ± 0.28	7.14 ± 0.30*	6.95 ± 0.35*
Em, cm/s	13.04 ± 0.60	12.95 ± 0.46	8.42 ± 0.79*	7.73 ± 1.17*
Am, cm/s	6.78 ± 0.38	6.68 ± 0.39	7.49 ± 0.87	7.91 ± 0.85

Values are means ± SE; n = 11/group. ACC, myocardial acceleration during isovolumic contraction; Sm, peak systolic mitral annulus velocity; Am, peak late diastolic mitral annulus velocity.
