Addressing Medication Non-adherence in Patients With Poorly Controlled Hypertension Using Urine Mass Spectrometry

* Hypertension is the single largest contributor to cardiovascular disease and death. While adequate control of hypertension reduces risk of disease, many patients have uncontrolled hypertension. This is often due to medication non-adherence. Left undetected, patients are prescribed additional medications, and referred to multiple specialists for investigations - leading to increased healthcare costs.
