I have been on warfarin longer than most (56+ years) I have a very old design aortic mechanical valve. My INR range has been 2.5-3.5 since the INR system was developed in the 1980s........and about 18 seconds PT(1.6 INR) before the INR system. I've never had an uncontrollable bleed that required more than first aid and/or some stitches. I've had one stroke (1974) due to a low INR and my ignorance of ACT that left me permanently partially blind.......that ain"t no fun. I only fear INR numbers below 2.0 and never let my INR stay around 2.0 or below. There is an old saying about bleeding and clots......" blood cells can be replaced but brain cells can't".Fewer bleeds with the lower INR. That counts minor and major bleeds.
But, 3x as many strokes, with the lower INR range.
BTW, with the full approval of my cardio and PCP I try to keep my INR at, or above 3. I fell about 3-4 months ago and broke three ribs......but didn't bruise. So much for that "old wives tale".
