ABSTRACT

Continuous monitoring of highly complex cardiovascular patients can provide valuable support for clinical decision-making, and wearable devices have emerged as promising allies in this scenario. This case report describes a patient with complex coronary artery disease, and recurrent episodes of nocturnal angina that persisted despite therapeutic optimization. After initiating monitoring with wearable devices and specialized follow-up, the integrated analysis of the monitored parameters, combined with the symptoms reported by the patient, raised suspicion of obstructive sleep apnea as a triggering factor for the anginal episodes. Subsequent diagnostic investigation confirmed this condition. This case illustrates how wearable devices, when combined with appropriate clinical interpretation
