bad breath sinus drops

I am 16 years old, I'm not sure if I have asthma and lung problems or a heart problem?
Sometimes I have trouble breathing, and I can not run long distances without having to breath. Sometimes I have bronchitis, but I'm not sure if it related. I use a regular inhaler that always helps my shortness of breath when it happens. Also cough a lot, a couple of times a day, the cough is not painful, and sometimes when coughing out mucus. I also have a stuffy nose and sinus headaches a lot. Is this a serious heart problem? Because a child in my school last year had the heart disease and heart just stopped randomly when running and died. Also, the smoke, but please do not give me lessons on it, I know how bad it is for me and I'm trying to quit, but if your answer is only will consist of a conference on smoking, no bother. In addition, when exercising or running long distances for a while, I start to cough and wheeze. Any non-conference answers?
Sounds more like a lung issue. Very unlikely to heart disease. Heart disease can present with difficulty breathe though. Other symptoms suggestive of heart disease would be chest pain, orthopnea (shortness of breath worse on lying down) and generalized swelling. It appears that you may have exercise-induced asthma. I know I want to hear, but I have to say. You need to stop smoking, but of course you already know. Ask your doctor, because the simple breathing tests (spirometry) can be used to assess asthma. Sometimes the stress test required. Shortness of breath may be secondary to other causes, such as deconditioning, or anemia (blood counts). Your doctor will determine if further evaluation is appropriate. Congestion nasal and sinus headaches may be seasonal allergies or chronic sinusitis. Asthma is more common in people with seasonal allergies. You can try antihistamines (Zyrtec, Claritin, Allergra, Benadryl) and decongestants (Sudafed) for these complaints. Sometimes a nasal spray may also help. Allergies can cause sinusitis post-nasal drip, which was coughed back out of the lungs. Talk to your doctor. Good luck.
