Evaluation of SCORE Cardiovascular Risk Scoring System in Non-Dipper and Dipper Normotensive Individuals

Objective: reduction of blood pressure (kb) by more than 10% over daytime measurements shows that circadian changes occur. the presence of this daily change is defined as the dipper kb pattern which is a normal finding. nondipper bp was shown to be significantly associated with organ damage and deadly non-fatal cardiovascular disease (kvh). the score risk system assesses the 10-year risk of the first lethal atherosclerotic event. the aim of this study was to investigate whether there is a relationship between non-dipper bp and score risk system in normotensive individuals. material-method: in this study, 100 consecutive patients who were normotensive were evaluated prospectively. 52 of them were in normotensive non-dipper group and 48 were in normotensive dipper group. non-dipper and dipper patient groups were determined according to akbi. according to score system, risk factors such as age, gender, smoking, systolic blood pressure (skb), total cholesterol (tk) and hdl cholesterol were used to calculate the risk of 10-year fatal kv event. results: score risk system was significantly higher in the non-dipper normotensive study group (p = 0,005). ldl and tk values were significantly higher in non-dipper group. in akbi, skb and diastolic kb (dkb) were significantly higher in non-dipper normotensive study group at night (p <0,001). although there was a moderate correlation between score risk ratio and day to night skb rate of change, there was a significant negative correlation and a negative but significant negative correlation with day and night dkb rate of change (r = 0,- 386, p <0,001; r = -0,294, p = 0,004). conclusions: in this study, there was a significant relationship between non-dipper patern and score risk system for the first time. the high probability of a 10-year fatal kv event calculated by the score risk system in the non-dipper patient group revealed the importance of follow-up with akbi in normotensive individuals.
