Figure 1 Comparison of the left ventricular (LV) mass index, plasma brain natriuretic peptide (BNP) level, and plasma atrial natriuretic peptide (ANP) level between the two groups. The vertical bars indicate the range of values. The middle horizontal bars indicate means, and the upper and lower horizontal bars indicate standard errors (SEM).

Figure 2 Comparison of plasma norepinephrine level, plasma renin activity, and plasma aldosterone level between the two groups. The vertical bars indicate the range of values. The middle horizontal bars indicate means, and the upper and lower horizontal bars indicate standard errors (SEM). DHF = diastolic heart failure.
