Heart symptoms that should not be ignored include chest discomfort or sudden pains, anxiety, dizziness, extreme fatigue, and persistent coughing or wheezing, according to WebMD. A rapid or irregular pulse, shooting pains from the chest to the shoulders or the arms, and abdominal swelling are also symptoms of heart failure.
Individuals who experience nausea or a lack of appetite when accompanied by chest discomfort should not ignore the symptoms and contact a medical professional, suggests WebMD. Pain that comes and goes in the arms and between the shoulders is a sign of a heart problem that should be reported to a medical professional.
Shortness of breath during minimal exertion can indicate heart problems or chronic obstructive pulmonary disease, explains WebMD. Individuals who feel winded while resting should not ignore the symptom. Excessive sweating during minimal exertion is also a sign of heart problems. Individuals who break out into a cold sweat should report the symptom to a medical professional. Heart problems can also cause fluid to accumulate within the body, which causes swelling and sudden weight gain. Individuals with a loss of appetite and swelling in the abdomen, legs, ankles or feet should not ignore the discomfort or dismiss the pain.
