Abstract
Objective: To investigate the effect of individualized antihypertensive therapy on the blood pressure and left ventricular hypertrophy (LVH) of hypertensive patients with coronary heart disease (CHD). Methods: We conducted a prospective study from Sep. 2014 to Dec. 2015 in Chinese PLA General Hospital. A total of 650 patients complicated with non-dipper or reverse-dipper hypertension and CHD were enrolled. All the participants were divided into non-dipper (n=259) and reverse-dipper (n=391) group according to their 24h ambulatory blood pressure monitoring (ABPM) reports. Patients who took short-acting antihypertensives changed their medicine to long-acting ones. Patients who had already taken long-acting antihypertensives switched to nighttime or added antihypertensives at night. Self-measured home blood pressure was recorded before going to bed and in the morning. All patients were regularly followed up by face-to-face surveys and clinic BP was recorded every 3 months. After 1 year's follow-up, the effect of individualized antihypertensive treatment on circadian rhythm of blood pressure was evaluated by 24h ABPM. The effect of individualized antihypertensive treatment on LVH was evaluated by echocardiography. Results: After 1 year's individualized antihypertensive therapy, the clinic BP and 24h ABPM of the patients were decreased. BP rhythm in 44% of the non-dipper and 57% of the reverse-dipper patients restored to normal. LVH were returned to normal in 44% of the non-dipper patients and and 48% of the reverse dipper patients, respectively. Left ventricular mass index (LVMI) were (59±12) kg/m(2.7) vs (48±10) kg/m(2.7) (P<0.01), and (63±13) kg/m(2.7) vs (48±11) kg/m(2.7) (P<0.01) respectively in non-dipper and reverse-dipper group before and after individualized antihypertensive treatment. Conclusion: Individualized antihypertensive intervention of abnormal blood pressure circadian rhythm can effectively restore the circadian rhythm of blood pressure and reverse LVH in hypertensive patients with CHD.
