N/A Background: 24-hour noninvasive ambulatory blood pressure monitoring (ABPM) has been shown to be superior to casual BP in predicting target organ involvement in patients with hypertension and assessing anti-hypertensive therapy. This study was done to examine the relation of BP decline from day to night to the echocardiographic parameters of left ventricular anatomy in unselected hypertensive patients and normotensive subjects undergoing 24-hour noninvasive ABPM. Methods: The effect of variation of blood pressure on the echocardiographic parameters of left ventricular hypertrophy were investigated in 71 consecutive subjects. (47 patients with essential hypertension and 24 healthy normotensive subjects). 24-hour noninvasive ambulatory blood pressure monitoring and cross-sectional and M-mode echocardiography were done to examine the relation between ABPM and echocardiographic LVH. Results: 24-hour ambulatory blood pressure was lower than casual blood pressure, and weak relation was noted particularly in patients with mild-to-moderate hypertension. The continuous monitoring of BP throughout day shows characteristic circadian pattern. The highest BP was recorded at 10 am and lowest value was at 2 am-4 am. Ambulatory daytime blood pressure (6 am-8pm) was higher 15% than night-time blood pressure (8 pm-6 am), The correlation coefficient of daytime systolic blood pressure was r=0.42 (p<0.01), twenty-four hours systolic BP was r=0.41 (p<0.05). The daytime and 24 hours systolic BP seems to be more closely related to LVH than night-time BP, but the correlation was not high enough in our study. Conclusion: 24-hour ambulatory blood pressure monitoring is more useful than casual BP in patients with hypertension, and LVH in echocardiography is more closely related to daytime and 24 hours systolic BP than night-time BP.

This study was conducted to evaluate the property of lipoprotein(a)[Lp(a)] as an acute phase reactant. Lp(a) consists of low density lipoprotein and apolipoprotein(a), specific glycoprotein. It is generally accepted that high concentration Lp(a) is an independent risk factor for cardiovascular disease. However, Lp(a) level cannot be lowered by nonpharmacologic and pharmacologic methods for hyperlipidemia. Although Lp(a) is thought to be an acute phase reactant, there is still controversy. A total 22 premenopausal women who underwent transabdominal hysterectomy with/without unilateral salphingoophorectomy were enrolled. Lp(a) and lipid profiles were measured before, at 1 week and at 1 month after operation. In contrast to other lipids, Lp(a) concentration was elevated by 96.7% from 18.1±2.6 ㎎/dL to 35.6±27.1 ㎎/dL at 1 week after operation. At 1 month, the concentration returned to basal level. Low density lipoprotein cholesterol was lowered only by 11.2%, and total cholesterol and high density lipoprotein cholesterol decreased after operation. In conclusion, Lp(a) is thought to be an acute phase reactant and this property might be involved in the pathogenesis of atherosclerosis.
