Does every coronary blockage need a stent?

I am looking for clear information about coronary angiography. Does every coronary blockage need a stent?

Does every coronary blockage need a stent is a common cardiology question. The answer depends on your age, symptoms, medical history, medicines and overall cardiovascular risk. In general, coronary angiography should be interpreted in context rather than from one symptom, reading or test result alone. Treatment is individualized. Depending on the condition, management may include lifestyle changes, control of blood pressure, diabetes and cholesterol, prescription medicines, and in selected patients a procedure or surgery. Do not start, stop or change heart medicines without discussing it with the prescribing clinician, because drugs such as antiplatelets, anticoagulants, beta blockers and blood pressure medicines may have important benefits as well as bleeding, blood-pressure or heart-rate effects. Arrange medical review if symptoms are new, recurrent, worsening, occur with exercise, or are associated with fainting, significant breathlessness or chest discomfort. For people searching for information about coronary angiography, heart health, cardiology symptoms, heart disease prevention and cardiac tests, the safest approach is an individualized assessment rather than self-diagnosis from internet information. This information is educational and does not replace advice from a qualified doctor or cardiologist.
