There are many diagnostic tests available today which can show if you have heart or vascular disease. In individuals who have known heart or vascular disease these tests can show if there has been any progression.
If the goal is to evaluate your heart's rhythm then an electrocardiogram, Holter monitor, or event monitor may be indicated. If the size, structure, or function of your heart needs to be evaluated then an echocardiogram may be what you need. These tests can be very helpful if someone has high blood pressure, dizziness, palpitations, a murmur, edema (fluid retention), or shortness of breath, just to name a few.
If the goal is to rule out significant coronary artery disease then a stress test or a stress echocardiogram may be what you need. These tests are very helpful if someone is having chest pain, palpitations and/or significant shortness of breath while exercising.
If you would like to determine your current risk level for developing heart or vascular disease then a Carotid Intima-Media Thickness test (CIMT) is an excellant way to find out. This test is very helpful if someone has risk factors present such as a strong family history of heart or vascular disease, abnormal cholesterol and/or triglyceride levels, high blood pressure, diabetes, obesity, etc.
