Measure
Active Arm
Patients will be discharged from the hospital with the telemedicine package. If the patient develops possible cardiac symptoms and seeks medical attention, the data provided by the telemedicine package will be acted upon, as appropriate, by the trial cardiology team. With remote follow up over the phone at 3, 6 and 9 months. Active Arm: Patient develops possible cardiac symptoms, takes an ECG, BP and oxygen saturation as per their training. Patient will receive a phone call by the trial cardiologist who will have access to a high-quality ECG trace, as well as blood pressure and oxygen saturations, and coupled with the clinical history, can decide on the most appropriate course of further management. With remote follow up over the phone at 3, 6 and 9 months.
Control Arm
Standard routine clinical care will be carried out, with remote follow up over the phone at 3, 6 and 9 months. Control Arm: Standard routine clinical care will be carried out, with remote follow up over the phone at 3, 6 and 9 months.

SECONDARY outcome

Timeframe: 3 months

Population: Analysis includes only participants who completed the SF-36 and SAQ-7 questionnaires at 3-month follow-up time and had corresponding baseline data. The number of participants analyzed is therefore smaller than the number originally assigned to each arm in the Participant Flow, due to non-return of mailed questionnaires and missed follow-up assessments.

Quality of life was assessed using the SF-36 and Seattle Angina Questionnaire-7 (SAQ-7). Both instruments generate domain scores from 0-100, with higher scores indicating better health status or angina-related quality of life. Questionnaires were completed at baseline (pre-discharge) and 3 months post-discharge, and follow-up scores were compared with baseline values.
