Symptoms of heart disease include chest pain, shortness of breath, irregular heartbeats or palpitations, and fast heartbeat. Dizziness, weakness, sweating and nausea can also be symptoms of heart disease, according to WebMD. Anyone experiencing these symptoms should seek evaluation by a doctor right away.
The most common symptom of heart disease is chest pain, which is also called angina. Angina may feel like heaviness or pressure and discomfort in the chest, or it can be felt as pain, squeezing, burning or aching, notes WebMD. Angina can also be felt in the back, jaw, throat, neck, arms and shoulders.
Heart disease that is caused by abnormal heartbeats or heart arrhythmia has its own unique symptoms, although some are similar to traditional heart disease symptoms. Symptoms of heart arrhythmia include fluttering in the chest, slow or racing heartbeat, lightheadedness, discomfort in the chest, and shortness of breath, notes Mayo Clinic.
When heart disease is caused by weak heart muscle, which is known as dilated cardiomyopathy, symptoms include fatigue, irregular heartbeat, lightheadedness, breathlessness at rest and with exertion, and swelling of the feet, ankles and legs, according to Mayo Clinic.
Infections of the heart, including pericarditis, myocarditis and endocarditis, have a special set of symptoms, including fatigue, fever, weakness, swelling in the abdomen or legs, and cough, notes Mayo Clinic.
