Relationship between Blood Pressure Fluctuations and Cardiac Arrest Outcomes in Patients with Pre-Existing Hypertension

The effects of both increased blood pressure and blood pressure variability have significantly affected the survival and neurological outcome of out-of-hospital cardiac arrest (OHCA) patients. Our study presented a cross-sectional to evaluate and analysis outcomes of blood pressure fluctuations' effect on patients with hypertension in pre and post-cardiac arrest. A cross-sectional study involving one hundred and five hypertensive patients who are comprised of both sexes and aged between thirty-eight and seventy years diagnosed with various hospitals scattered all different hospitals in Iraq was performed from January 2023 to January 2024. Blood pressure measurements such as systolic and diastolic blood pressure taken prior to cardiac arrest activity at admission and after resuscitation were studied. When it pertains to the analysis of cardiac arrest outcomes, survival rates were calculated as to admissions to hospitals while also looking at neurological outcomes and in-hospital mortality. Our outcomes shown that almost patients had BMI with 28.7 ± 4.6 {kg/m2}, systolic blood pressure was 130.1 ± 10.3, diastolic blood pressure was 80.4 ± 8.6 after - Arrest (mmHg), survival to hospital admission got 64.76%, neurological outcome (CPC 1-2) got 31.43%. Mortality rate in hospitals had 35.24%. Our study indicates that high blood pressure causes a severe decline in the quality of life of patients with OHCA
