Abstract/OtherAbstract:
BACKGROUND: Heart rate (HR) is a basic cardiovascular parameter. The relationship between (HR) and cardiovascular mortality and morbidity has been indicated in clinical trials and epidemiological studies.
OBJECTIVE: The evaluation of the relationship between HR upon hospital admission and the in-hospital prognosis in a group of patients with STEMI.
METHODS: The medical records of 927 patients (pts) were subject to retrospective analysis. The patients were classified on the basis of HR upon hospital admission: <60 bpm (75 pts), 70-79 bpm (245 pts), 80-89 bpm (172pts), 90-99 bpm (134 pts), and ≥100 bpm (132 pts). A group of patients with HR of 60-69bpm on hospital admission (169 pts) constituted a reference group. Patients with atrioventricular blocks and arrhythmias were excluded from the analysis. Early mortality and co-existing diseases were evaluated in the study population.
RESULTS: Patients with HR ≥90 bpm demonstrated heart failure symptoms considerably more often than patients with HR of 60-69 bpm (p = 0.0010). In-hospital mortality was significantly higher in patients with HR of more than 90 bpm and bradycardia. Relationship between HR and cardiovascular mortality is shown with a J-shaped curve.
CONCLUSIONS: 1. : HR is strictly correlated with the early cardiovascular mortality in a population of patients with STEMI. 2. Relationship between HR and early mortality is demonstrated by the J-shaped curve.
