ICU stays were for heart failure but not in the usual way. Hypertension made my lungs fill with fluid that compressed the heart. Got that under control TOO WELL=a follow up showed excessive potassium in my blood, so I had to go back in order to flush it out. Monitoring BP daily and most days are pretty good.
Unfortunately, all this happened just as I was re-learning to walk (cuz of knee problems). But I'm isolated and doing well considering.
