A dental professional, prior to start a dental surgery or treatment must be aware of the physiological state of the patient. This is important because the dental treatment of a medically compromised patient specially with cardiac abnormalities could result in severe complications. Moreover the awareness with cardially compromised patient helps an emergency dentist to decide the procedure that would be appropriate and precautions that are necessary. Also the drugs that a dentist prescribes could have severe cardiovascular effects. Therefore a treatment plan must be devised after cosidering all pros and cons of the condition.
