Heart Attack: Along with chest pain, a heart attack may cause shortness of breath, cold sweat, dizziness or lightheadedness, nausea, vomiting, and palpitations (irregular heartbeat). These symptoms indicate an urgent issue that requires hospitalization.
Gas Attack: Gas pain is usually accompanied by bloating, excessive burping, flatulence, and a feeling of fullness in the abdomen. It usually does not cause sweating, dizziness, or difficulty breathing, though it might cause anxiety (when people think it is heart related, often mimicking symptoms)
