| dc.description.abstract | Cardiovascular disease is a disease that attacks the heart and blood
vessels. Many types of cardiovascular diseases, but the most famous are coronary
heart disease and stroke. Coronary heart disease is a disease that is the first cause
of death that occurs in the world caused by risk factors and the length of time of
survival of coronary heart disease patients, then using survival analysis with the
Cox Proportional Hazard model and Accelerated Failure Time model.
Comparison between Cox Proportional Hazard model and Accelerated Failure
Time model expedited time can be determined by the survival time with a safe
function, the hazard function and density function (comparison of income) of
each questioned duration of time with the help of different AIC policies and the
rate of deterioration. Estimation of the survival time of this cardiovascular case
is determined from the Cox Proportional Hazard’s hazard ratio model and the
Accelerated Failure Time’s time ratio model. The results showed that the
Accelerated Failure Time model was better than the Cox Proportional Hazard
model because the rate of deterioration and the AIC value was smaller than the
other models and related to risk factors, namely the age and status of diabetes
mellitus and the length of survival of the patient for 11 days obtained from the
estimation of the survival time distribution between the Cox Proportional Hazard
model and the Accelerated Failure Time model.
