###Human: Is my shortness of breath due to infection of the heart? ###Assistant: Hello. I have carefully reviewed your detailed query. You definitely need an in-person cardiologist consultation for appropriate evaluation of the issues. Only EKG is not conclusive in such a case. We need to listen to the heart and then go for thorough physical exam. Tests may include but not limited to exercise stress test, echocardiography, thallium scan, chest X-ray, CT scan, angiography and others if needed. Once ruled out we can say with confidence if there is any issue that needs proper management. Yes, an infection can spread from the teeth and throat infection to heart and can be diagnosed. Blood work also helps in this regards to find out infectious agents in blood and due to infection, any changes in the blood. If there is blockage to any of the blood vessels supplying the heart, there are chances of shortness of breath and patient can be short of breath even talking for some time, little physical activity or climbing the stairs. Do not panic and just follow as directed by your primary care and go for cardiologist evaluation. Meanwhile, go for apicoectomy and keep in touch with your dentist. Hope it helps.
