An angiogram is recommended by a cardiologist to check the flow of blood to one's heart and the areas, which are restricted by blockages, the intensity, and size of the blockages as well. The expert cardiologist shall also advise you about how you may prepare yourself for the angiogram. For instance, you may be asked to stop the dose of blood thinners other than aspirin before the angiogram procedure, you will be asked to abstain from eating as well as drinking even water a few hours before the process and you will also receive certain medications so that you may relax before the angiogram procedure begins. The process of angiogram would not take more than 30 to 45 minutes but in case the angiogram proceeds into angioplasty, then it may take about 1 to 2 hours. The image of the angioplasty report helps in assessing the percentage of the blockage and whether you need any immediate surgery or your blockages could be prevented and treated with cardio exercises and medications. Serious problems during the angiogram are very rare and there is nothing serious to be watchful about. Your cardiologist can advise you about what you should do and what you shouldn't after the treatment. It is generally advised to stay away from heavy work such as lifting weights, doing hard training and many others. The after-care treatment is also quite important and your cardiologist would be able to carve out a routine specifically based on your health conditions.
