To identify factors related to left ventricular diastolic dysfunction in hypertensive patients, and to create a scoring system from those related factors.
Design and method:
A cross sectional study was conducted in Tarakan General District Hospital North Borneo with hypertensive subjects on October 2016. Patients characteristics, all factors related to left ventricular diastolic dysfunction, and echocardiographic data were collected and analysed.
There were 132 total samples in this study, and left ventricular diastolic dysfunction was found in 40,2% samples. From logistic regression analysis, age more than 55 years old (OR 4.97, 95% CI 1.60–15.42), poor blood pressure control (OR 22.33, 95% CI 4.11–121.48), left ventricular hypertrophy (OR 4.23, 95% CI 1.14–15.72), and abnormal fasting plasma glucose (OR 13.24, 95% CI 2.89–60.67) were found to have a significant relation with left ventricular diastolic dysfunction and became a final model variables of scoring system. Left ventricular diastolic dysfunction scoring system could be generated from those variables final models. Calibration and internal validation tests for this scoring system showed good results.
A scoring system can be generated to detect left ventricular diastolic dysfunction in hypertensive patients.
