Hi,
Welcome to icliniq.com.
First of all I would like to make it clear that raise in troponin level is not criteria whether a person will live for one to three years. Somebody has totally misguided you and you are getting panic unnecessarily. Secondly, I will clear your doubt step by step. But, before that I want to ask few questions. What is your age? Since how many times did you had episode of chest pain? If you are a smoker then please elaborate how much and since how long you had been smoking? What is your body stature obese, thin or normal? How much frequent you suffer from palpitations? When did gastritis was diagnosed? Had any kind of treatment apart form antacid? Did you suffer from GERD (gastroesophageal reflux disease)? Did palpitation or pain associated with meals? What is your life style, appetite, sleep, stress and physical activity? Have you ever get your blood pressure and lipid profile (cholesterol) done? Troponin is a kind of cardio-specific enzymes which get raised only when there is injury to myocardial muscle that is heart muscle. The reason could be a direct injury or ischemic injury due to lack of blood supply or anything else. I read your CT guided angiography report. It is suggestive of that you do not have any kind of blockade. So, you should not be so much panic as report goes in your favor. Once troponin level get raising it remain elevated for several days and in some person it take long time to become normal. According to your symptoms, I think that you could have unstable angina. It is a transient state of MI (small heart attack) in which artery supplying to your heart become narrow for time being and lead to release of troponin. According to report that is not permanent so nothing to worry. But, still we have to evaluate it properly. Glyceryl trinitrate - GTN spray will cause vasodilation (dilation of arteries of heart) and given in patient of unstable angina. Moreover, you do not get relieve too much as you also have a doubt about costochondritis. Both the things are contradicting each other. As you have described about some heart attack symptoms, my advise is to get a stress echo or TMT, lipid profile and ECG done. Also send me the details of your current medication. Till then I will advise you to take the following medicine. Take Tablet Aspirin 150 mg once daily after meal, Tablet Clopidogrel 75 mg once daily, Capsule Omeprazole 20 mg twice daily in empty stomach in the morning and before dinner, Tablet Propranolol 20 mg whenever you feel palpitations, Tablet Alprazolam 0.25 mg once daily at bed time, Tablet Multivitamin once daily for 15 days and Apply topical anti-inflammatory gel locally in the area of pain. You need to raise your good cholesterol level which is HDL (high-density lipoprotein) which is good for heart. If you are a non-vegetarian then fishes and fish oil which contain Omega-3 fatty acid to increase HDL levels. Some food product which can increase are whole grains, whole wheat products, almonds and nuts. Fibrates like Fenofibrate very useful. Niacin (Vitamin B3) is very useful in increasing HDL levels. Follow life style modifications like quit smoking, exercise and avoid oily food. There is nothing to get panic. So, do not think too much and do not believe in myths. Cheers and enjoy your life.
