SUMMARY
OBJECTIVE:
Left atrium enlargement is common in hypertension due to left atrium inflammation. Monocyte to high-density lipoprotein cholesterol ratio, an inflammation marker that has become very popular in recent years, is associated with many cardiovascular diseases. The aim of this study is to investigate the monocyte to high-density lipoprotein cholesterol ratio level to predict the Left atrium enlargement in hypertensive patients.
METHODS:
A total of 216 participants (i.e., 115 hypertensive and 101 control group) were enrolled. Left atrial volumes and left atrial volume indexes were calculated using transthoracic echocardiography. The monocyte to high-density lipoprotein cholesterol ratio was calculated as the ratio of monocyte to high-density lipoprotein cholesterol levels.
RESULTS:
The left atrial volumes, left atrial volume indexes, and monocyte to high-density lipoprotein cholesterol levels were significantly higher in the hypertensive group than in the control group (43.3±12.4 versus 31.4±7.9, p<0.001; 22.9±5.8 versus 17.1±3.7, p<0.001; 11.4 [4.2-25.0] versus 8.4 [3.5-18.0], p<0.001, respectively). On the multivariate logistic regression analysis, monocyte to high-density lipoprotein cholesterol ratio (OR 1.38; 95%CI 1.20-1.57; p<0.001), (OR 1.28; 95%CI 1.16-1.42; p<0.001), age, and sex (female) were the independent predictors for hypertension.
CONCLUSIONS:
The increased monocyte to high-density lipoprotein cholesterol ratio level was associated with hypertension and increased left atrial volume indexes. The results of this study supported the presence of inflammation, measured with a readily available and inexpensive marker, in hypertensive patients and revealed the association with left atrial enlargement.
