As per my understanding the patient is suffering from double vessel disease with the blockage of 90% and 67% .The line of treatment , medical or surgical that is angioplasty or CABG will only be decided by the cardiologist once he evaluates the patient completely .The treatment depends a lot on patient's general condition, associated comorbidities. Post treatment rehabilitation has to be kept in mind, healthy lifestyle, right eating, de-stressing will be of help along with regular follow up with doctor. Consult a cardiologist - Best Cardiologist in India. Hope you get the much needed support.
