Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. I understand your concern and would explain that heart attack symptoms are represented commonly by chest pain, dyspnea, and other associated symptoms. Generally speaking, when there is chest pain, the suspicions are raised about a possible heart attack. But in fact, the majority of chest pain is extra-cardiac in reality. Several causes like musculoskeletal disorders (inflammation/infection/injury), backbone degenerative disorders, pleural or pericardial inflammation, gastroesophageal reflux, gastritis, hiatal hernia, esophageal spasms, costochondritis, pulmonary embolism, and even shingles (representing by typical intercostal skin eruptions), etc. may be the reasons for heart attack - like symptomatology. It is a good news, as the ER doctors have excluded any possible cardiac implications or other serious health disorders. But, at the same time, it is important to properly differentiate the exact cause of her complaints. That s why a comprehensive clinical investigation should be done and additional medical tests performed. In case her clinical symptomatology keeps persisting, you should discuss with her attending doctor (internist) for a careful differential diagnosis. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Ilir Sharka
