Cumulative Probability of Occurrence of Cardiac Complications in Type 2 Diabetes Mellitus Using Survival Analysis in Patients Referring to the Diabetes Clinic, Bu-Ali Hospital, Zahedan, Iran

Background and Aim:

 Cardiovascular complications in diabetes mellitus are one of the most common complications of this disease. The aim of this study was to determine the cumulative probability of occurrence of cardiac complications in type 2 diabetes mellitus using survival analysis in patients referring to the Diabetes Clinic, Bu-Ali Hospital, Zahedan, Iran.

This was a descriptive and analytical historical cohort study using the survival analysis method in 2020 on 410 patients referring to the Diabetes Clinic, Bu-Ali Hospital, Zahedan, Iran. Data were collected and analyzed using the SPSS-v21 software, the statistical tests being descriptive tests, followed by the Kaplan-Meier method and the Cox proportional hazards model of survival.

The results of this study showed that 122 individuals (29.7%) of the diabetic patients had cardiac complications. The median survival time (in months) of the occurrence of cardiac complications was found to be related to fasting and two-hour postprandial blood sugar levels (p<0.05). Further analysis of the data showed that two variables, namely fasting blood sugar and regular visits, remained in the final model of the multiple Cox regression.

The findings of this study showed that the cardiac complications of diabetes in the population studies are relatively high. Therefore, it is essential to plan and implement interventions aiming to change lifestyle and control regularly blood pressure, cholesterol and blood sugar in the patients in order to prevent the disease
