Evaluating the relationship between the pulse pressure and diastolic blood pressure index with quality of life and survival in patients with reduced ejection fraction heart failure at 6-month follow-up in Shahid Madani hospital

Abstract

It is believed that maintaining systolic blood pressure and diastolic blood pressure can increase the mentality and enjoyment of life along with the better performance of the heart in pumping blood, more studies need to investigate the relationship between blood pressure and pulse pressure on the quality of life and survival of patients with heart failure. In this study, the relationship between systolic blood pressure, diastolic blood pressure, and pulse pressure on the quality of life and survival of patients admitted to the HFrEF hospital in a 6-month follow-up was conducted. Methods: The present study is a cross-sectional descriptive study that has a prospective approach and was conducted during the year 2021 with the participation of patients hospitalized in Shahid Madani Hospital (Tabriz University of Medical Sciences). The sample size was determined based on the time limit of the study. First, written consent was obtained from patients with heart failure with EF less than 40%. In case of illiteracy, the consent was obtained by the researcher. After obtaining consent, systolic and diastolic blood pressure were measured before admission. Then the quality of life (QOL) sf36 form was given to the patients. QOL form, sf36 was read in illiterate patients. The patient's blood pressure was measured by the researcher with a Richter sphygmomanometer.. Results: The lower the systolic blood pressure (P˂0.00014), diastolic blood pressure (P˂0.009) and pulse pressure (P˂0.0005), the quality of life score (SF-36) will decrease significantly; Also, the other part of the results indicated that the lower the systolic blood pressure (P˂0.00001), diastolic blood pressure (P˂0.0003) and pulse pressure (P˂0.00001), the quality of life score (Minnesota) will decrease significantly. Six-month mortality was observed in 18 patients (22.5%) in the present study. Studies indicated that the mortality rate in pulse pressure in the range of less than 50 mm Hg and above 65 mm Hg is higher than other ranges; Also, the death rate in diastolic blood pressure is high in the range of less than 65 mm Hg and higher than 85 mm Hg.
