[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Since you are a active smoker, we should definitely rule out heart and lung diseases for your symptoms. So consult cardiologist and get done ECG, 2d echo and stress test (trade mill test) to rule out heart diseases. Get done chest x-ray and PFT (Pulmonary Function Test) to rule out lung diseases. If all these are normal then no need to worry about major heart and lung diseases. Sometimes stress and anxiety can also cause similar symptoms. So avoid stress and tension, be relaxed and calm. And please quit smoking as soon as possible because it is not a good habit. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
