Hypertension Management in Cancer Patients

This is a 12-week prospective study with two phases. Participants will use the QardioArm device to obtain 3 separate blood pressure measurements per week (2 morning, 1 evening). The QardioArm device will only be used as a tool to gather data. In Phase 1 (Weeks 1-4), participants will self-monitor their blood pressure using the Qardio Bluetooth device. In Phase 2 (Weeks 5-12), we will implement the auto-messaging system triggered by a weekly average systolic blood pressure \>140 mm Hg or diastolic blood pressure \>90 mm Hg.
