I am 60 years of age, was recently diagnosed with stage 2 CHF and a mild MI, with minimal ischemic damage. Cardiac arteries and those in the neck completely b forest, normal cholesterol levels. I spent a week in hospital. Now I am home, maintaining a reduced (academic) schedule, fluid restriction of 1.5 ml daily, low sodium (≤1000 daily). I am experiencing debilitating fatigue and nausea with vomiting. I also feel dehydrated and have dark Udine in reduced amounts, despite prescribed diuretics. Do I need to revisit the ER now?
