I want to find all patients who have had a diagnosis related to the circulatory system (ICD codes 390-459) as their principal diagnosis or admission diagnosis, with the first diagnosis occurring at any time, and the second diagnosis occurring on the same instance number but less than 136 hours and 12 minutes after the first diagnosis.
