Official title

Pilot Study to Determine the Feasibility and Patient Acceptance of Therapeutic Drug Monitoring to Improve Medication Adherence

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The investigators will interview patients and providers of patients who have hypertension and are seen in cardiology clinic about ways to discuss therapeutic drug monitoring with patients. The investigators will use these interviews to crease discussion tools to discuss therapeutic drug monitoring. The investigators will then draw one venous blood sample in a different group of patients who are seen in interventional clinic for 1 month followup after PCI. The investigators will assay this blood for therapeutic drug monitoring and will provide the results to their providers for discussion at their regularly scheduled followup cardiology visit. The investigators will have the patients and providers fill out a survey afterwards to determine how they viewed therapeutic drug monitoring.
