To analyze the level of plasma brain natriuretic peptide (BNP) and the related factors in the patients with chronic heart failure after anti heart failure treatment.

The subjects selected from our hospital in 45 cases of elderly patients with chronic heart failure from October 2014 to December 2016 in Guizhou Cancer Hospital, the clinical data of all patients were analyzed retrospectively, and the patients as the observation group, and 45 healthy persons in our hospital were selected as control group in this study. Two groups of subjects of systolic blood pressure, diastolic blood pressure, pulmonary congestion, pulmonary hypertension, compare the left ventricular ejection fraction, and affecting factors of the related results were analyzed.Comparison of the patients in the observation group before after anti heart failure treatment and treatment level of BNP patients, and to assess the resistance the treatment of heart failure.

There were significant differences in systolic blood pressure, diastolic blood pressure, pulmonary congestion, pulmonary hypertension and left ventricular ejection fraction between the two groups(P<0.05). The levels of BNP in the observation group were compared before and after treatment, and the difference was statistically significant before and after treatment (P<0.05).

Hypotension, pulmonary congestion and other related factors are independent risk factors of chronic heart failure. After the treatment of anti heart failure, the BNP level of patients can be significantly improved.
