Review on Biosensor: A Diagnostic tool for cardiovascular diseases

For the last few years there has been a sudden increase in the occurrence of cardiovascular disease and it has been the constant reason for the increase in mortality rate all over the world. For the diagnosis of CVD, the earlier diagnostic tools used were ECG and immunoassay analysis which in turn delayed the results and caused more inconveniences. Hence to reduce the mortality rate it is better to create biomarkers using biosensors that can easily detect the heart rates and we can also quickly diagnose the presence of CVD. The Biomarkers are made of Biosensors which is an analytical device comprised of nanoparticles with novel bioelectronics and nanotechnology platforms. A variety of biosensor techniques are also available to diagnose the presence of CVD. This review mainly focuses on the basics of Biosensors, Traditional diagnostic tools for CVD, and the current trends followed using biosensors for the identification of CVD mainly Myocardial Infarction (heart attacks). .
