The Role of Portable Biosensors in Early Diagnosis and Prevention of Cardiovascular Diseases

Cardiovascular diseases (CVDs) are the leading cause of death worldwide, highlighting the need for early and accessible detection strategies. Traditional diagnostics, such as ECGs and blood tests, often require clinical settings and may miss early indicators of disease. In contrast, portable biosensors offer real-time, continuous monitoring of biomarkers such as heart rate, blood pressure, and troponin levels. This study evaluates the effectiveness of biosensors in early CVD detection using simulated datasets and compares them with conventional diagnostic approaches. Findings suggest that biosensors improve sensitivity, patient compliance, and early diagnosis, potentially reducing mortality by up to 30%. The article also addresses adoption challenges and emphasizes the transformative role of biosensors in personalized digital health.
