| dc.description.abstract | Introduction:The term “cardiovascular diseases” (CVDs) refers to any disease affecting the heart or blood vessels. CVDs are the most common cause of death worldwide and the most responsible reason  for  10%  of  deaths  in  the  early  20th  century.  These  CVDs  can  emerge  as  myocardial infarction  or  ischemic  heart  disease,  stroke,  and  congestive  heart  failure.  For  diagnosing  CVDs, physical,  radiological  investigations,  and  laboratory  investigations  for  cardiac  enzymes  and  lipid profile are used. In clinical practices, cardiovascular risk prediction models are very important in the identification,  prevention,  and  staging  of  the  severity  of  CVDs.  Framingham  Risk  Score-coronary heart  disease,  Framingham  Risk  Score-cardiovascular  disease,  QRESEARCH-cardiovascular  risk algorithm,   Joint   British   Society   risk-calculator-3,   WHO/ISH   CVD   risk   prediction   charts,   and Atherosclerotic   Cardiovascular   Disease   risk-estimator   are   some   of   the   available   CVD   risk estimators. However, many of these estimators can be used only to evaluate individuals more than 40  years  and  to  assess  the  risk  for  10-years.   Therefore,  new  risk  estimators  are  needed  to overcome  the  deficiencies  of  the  available  risk  estimators.  Research  have  been  done  in  novel directions;  on  ratios  of  routinely  performing  hematological  and  biochemical  laboratory  parameters such as Neutrophil to Lymphocyte Ratio (NLR), Platelet to Lymphocyte Ratio (PLR), and Aspartate aminotransferase   to   Alanine   aminotransferase   ratio   (AST/ALT).   The   outcomes   indicate   a relationship between the above-said ratios and the risk for CVDs.  Conclusion:On  such  grounds,  this  review  describes  the  importance  of  developing  a  CVD  risk estimator by amalgamating some of the biochemical and hematological parameters, including NLR, PLR, and AST/ALT ratios, aiming to overcome the existing shortcomings | en_US |
