  • Difficulty breathing during daily activity or when lying flat
  • Swelling in your feet, ankles, legs, fingers or belly
  • Weight gain; three to five pounds over 24 hours
  • Increased urination at night and decreased urination during the day

  • Sudden or severe chest pain
  • Severe shortness of breath
  • Unexplained sweating or weakness
  • Trouble talking
  • Weak legs or arms
