But as the condition advances, signs and symptoms usually appear, including:  Breathlessness with activity or even at rest Swelling of the legs, ankles and feet Bloating of the abdomen due to fluid buildup Cough while lying down Difficulty lying flat to sleep Fatigue Heartbeats that feel rapid, pounding or fluttering Chest discomfort or pressure Dizziness, lightheadedness and fainting  Signs and symptoms tend to get worse unless treated. In some people, the condition worsens quickly; in others, it might not worsen for a long time.
