Embodiment Construction

[0020] The following descriptions of some representative embodiments are merely illustrative in nature and are not intended to limit the invention and its application or use. Throughout the specification, the term "value" refers to observed, recorded, measured or selected data. The term "fuzzy" refers to values ​​or non-values ​​whose value set bounds are not well defined. The term "fuzzy function" refers to a mathematical function representing fuzzy features. The terms "fuzzy engine" or "fuzzy sub-engine" refer to components that apply fuzzy functions to input values, these components may include processing steps or algorithms.

[0021] Now refer to Figure 1-5 , figure 1 is the cardiovascular disease risk fuzzy system 100 of the present invention.

[0022] The fuzzy system 100 includes risk factors 101 from people with type II diabetes as input to the fuzzy engine 103 . Risk factors 101 may be selected from: age, smoking status, systolic blood pressure, cholesterol leve...

Abstract

The present invention relates to a fuzzy system that provides a measure of global cardiovascular risk based on the risk factors associated with cardiovascular disease and stroke. The fuzzy system is of multiple input single output (MISO) wherein the inputs are the values of risk factors and the output is the measure of global cardiovascular risk.

Description

technical field [0001] The invention relates to the field of disease risk assessment, in particular to a fuzzy system for risk assessment of cardiovascular disease and stroke. Background technique [0002] Cardiovascular Disease (CVD) is a serious disease, which is one of the main causes of death. Although much is known about lifestyle risk factors and the pathogenesis of CVD, there are major gaps in understanding when it comes to specific populations. Much research is being devoted to overcoming these significant gaps. [0003] In 1948, the Framingham Heart Study (FHS) conducted a study that closely monitored the development of CVD in a large number of volunteers who had not yet shown obvious symptoms of CVD, heart attack or stroke , to identify common factors or features leading to CVD. The Framingham Heart Study continues to make important scientific contributions by enhancing its own research capabilities and leveraging its inherent resources. [0004] The Atheroscle...
