This study aims to evaluate the impact of two blood pressure management strategies—ambulatory blood pressure monitoring-guided medication and conventional daily single measurement—on the rehospitalization rates of heart failure patients in the intensive care unit. Heart failure patients from our intensive care unit were collected and evenly divided into two groups of 24 cases each according to the blood pressure management strategy. The ambulatory monitoring group collected 24-hour ambulatory blood pressure data and adjusted medication based on ambulatory blood pressure parameters; the conventional monitoring group measured blood pressure once daily and used medication based on the results. Statistical analysis compared the differences in ambulatory blood pressure parameters between the two groups, their correlation with cardiac function classification, and the differences in rehospitalization rates between the two groups. The results showed that the 24-hour SBP, DBP, and MBP changes in the ambulatory monitoring group were more significant during the day and night(P<0.05),with more precise adjustments of ambulatory blood pressure parameters and significantly higher rationality of drug use compared to the conventional monitoring group; the ambulatory monitoring group had a significant reduction in diurnal blood pressure variability(DBPV)and superior drug adjustment effects; ambulatory blood pressure parameters were significantly correlated with cardiac function classification, especially the daytime SBP and MBP, which showed statistical significance among patients with different cardiac function classifications(all P<0.05);in terms of rehospitalization rates, the ambulatory monitoring group was significantly lower than the conventional monitoring group(P<0.05).In summary, ambulatory blood pressure monitoring can effectively guide individualized medication for heart failure patients, improve blood pressure control, and significantly reduce rehospitalization rates.
