Proportional pulse pressure to heart rate ratio for estimation of in-hospital course in admitted acute heart failure patients

Abstract

Heart failure is a common cardiovascular disease. Hospitalization and in-hospital events is common and these have significant effects on morbidity and mortality of the patients with heart failure. Finding methods which can detect the risk of complications during in-hospital course, could help management of these patients. It is very important to find methods which is simple, available, inexpensive and easy to use by physicians. In this study we want to evaluate the association between systolic blood pressure, diastolic blood pressure and heart rate with complications during in-hospital course. Methods: Patients admitted with acute heart failure diagnosis in Shahid Madani hospital were entered in this study (150 patients). Patients’ data including, age, sex, cause of heart failure, comorbidities, consumptive drugs, proportional pulse pressure to heart rate ratio, laboratory and echocardiogarphic findings, in-hospital course including, length of stay, mortality, use of inotrope drugs, mechanical ventilation and worsening renal function was recorded. The association between proportional pulse pressure to heart rate ratio with in-hospital course was defined using regression analysis. Results: Low proportional pulse pressure to heart rate ratio is associated with increased length of stay and increased in-hospital course mortality and events.
