Biomedical diagnostic research is becoming increasingly important in the
modern medical profession. Infectious disease inspection, initial detection, chronic
disease treatment, clinical services and well-being hunt down are the various
applications of biosensors. Advanced biosensor technology permits the identification of
the disease and the examination of the patient’s responses to medication. Sensor
technology is crucial for a broad range of low-cost and practicable developed medical
appliances. Biosensors offer many possibilities because they are unambiguous,
ascendable and capable of synthesizing procedures. Cardiovascular disease(CVD) is
now recognized as the leading cause of death. It is estimated that the number of people
dying from heart disease and stroke will approach 20 million by 2015. The risk event
of unexpected death associated with it can be minimized by recognizing the challenges
involved in its beginning, symptoms, and early detection. Therefore, this chapter aims
to provide an idea for the diagnosis and therapeutics of CVD. Biosensors, created to be
utilized as quick screening instruments to detect disease biomarkers early on and
classify the condition, are revolutionizing CVD diagnosis and prognosis. Biosensors
have become faster, more accurate, portable, and environmentally friendly diagnostic
equipment as a result of advances in interdisciplinary study domains.
