Hi, welcome to our site. I am Dr Saumya Mittal, MD. Read your query. That is a very significant question and i appreciate your problem. I will try my best to answer your query Well the information is true. You need to understand that the heart attack occurs because the blood vessels supplying blood to the heart are compromised. They therefore are unable to supply too much blood to the heat muscles. More so when the need of blood is increased like in exercise. Therefore doctors suggest that the exercise should be avoided. The block or compromisation of the heart persists, short of surgery (stenting or CABG). The medicines we give are usually vasodilators and the try to keep the blood vessels open so that more flow of blood can occur through the compromised vessels. Thats why, another attack can happen, because the original cause of attack- the compromised vessel has not been treated. The pumping of the blood of course reduces after the heart attack, because the muscles are not working so effectively. If the healing is good, they may actually improve again. Suggest an angiography to evaluate the exact degree of the lesion. Meanwhile antiplatelets like aspirin and vasodilators like nitroglycerine should be continued (assuming there are no other contraindications to the medicines). I hope this helps you. Inform the reports mentioned above/if any other so I can be of help further. I have given you the answer to the maximum considering the information provided. The results of the tests could further enhance my answer to you. Please do understand that some details could be extracted from a detailed history and examination.
