Unadjusted and adjusted hazard ratios of left ventricular relaxation time constant (Tau) > 48 ms and peak early diastolic mitral annular velocity (e′) < 5.8 cm/s by Cox proportional hazards regression analysis.

	Unadjusted		Adjusted
		Model 1*	Model 2†	Model 3‡
Tau > 48 ms	2.57 (1.13–5.81)¶	2.45 (1.04–5.82)¶	3.12 (1.16–8.37)¶	3.23 (1.31–7.97)¶
e′ < 5.8 cm/s	3.47 (1.57–7.70)#	2.38 (1.03–5.52)¶	4.09 (1.75–9.57)#	3.81 (1.65–8.81)#

Data are represented as hazard ratio (95% CI).

*Adjusted for age, sex, hypertension, dyslipidemia, diabetes, and coronary revascularization after the index cardiac catheterization.

^†Adjusted for previous history of myocardial infarction, the number of coronary arteries narrowed, ejection fraction, systolic aortic pressure, and heart rate.

^‡Adjusted for use of β-blocker, angiotensin-converting enzyme inhibitors or angiotensin receptor blockers, calcium blocker, statin, and antiplatelet agents.
