Cardiovascular diseases (CVDs) are one of the leading causes of mortality worldwide. Continuous monitoring and early detection are critical for effective treatment and prevention. This paper presents an IoT-enabled smart healthcare system designed for real-time cardiovascular monitoring. The proposed system integrates wearable sensors, cloud computing, and mobile applications to monitor vital parameters such as heart rate, blood pressure, and ECG signals. The system enables real-time data acquisition, processing, and alert generation for abnormal conditions. Experimental results demonstrate the efficiency, reliability, and scalability of the proposed system, making it suitable for remote healthcare applications
