A risk scoring system for prediction of coronary heart disease based on multivariate analysis: development and validation.

Considering the multifactorial disposition and the need of primordial prevention of coronary heart disease (CHD), a risk scoring system for the prediction of CHD was devised at Govt Medical College, Nagpur, India.
