Figure 5 (A) Inverse correlation (y = –33.39x + 49.97) between the ratio of MMP-1 to TIMP-1 (log MMP-1:TIMP-1) measured in peripheral vein blood and ejection fraction in all subjects. (B) Direct correlation (y = 1.98x + 5.50) between log MMP-1:TIMP-1 measured in peripheral blood and left ventricular end-diastolic diameter in all subjects. EF = ejection fraction; LVEDD = left ventricular end-diastolic diameter; other abbreviations as in Figure 2.
