Dividing IgG against MDA-collagen type IV into quartiles showed that a high level of IgG against MDA-collagen type IV was associated with decreased risk of MI (OR 0. 61 (0. 400. 91) for 4thvs1st quartile, p=0. 002; Table2). IgG against native collagen type IV was present at detectable level in 17% of patients as opposed to 7% of controls (p < 0. 001). Controlling for major cardiovascular risk factors demonstrated that the presence of IgG against native collagen type IV was associated with myocardial infarction (OR 2 . 9 (1. 65. 4), p = 0. 001). Similarly, subjects in the highest quartile of IgM against native collagen type IV had increased risk of having suffered myocardial infarction (OR 3. 11 (1. 85. 4), p < 0. 001) after adjusting designed…
