چکیده
CHEST I 92 I 4 I OCTOBER, 1987 721 As part of an on-going population-based study of patients hospitalized with acute myocardial infarction (MI) in all 16 hospitals in the Worcester, Massachusetts Standard Metropolitan Statistical Area, temporal trends in the use of the pulmonary artery (PA) catheter were examined. Three thousand two hundred and sixty-three patients with validated acute MI during the calendar years 1975, 1978, 1981 and 1984 comprised the study population. There has been a consistent and significant increase in PA catheter use in patients with acute MI over time, from 7.2 percent in 1975, 13.8 percent in 1978, 14.8 percent in 1981 to 19.9 percent in 1984 (p<.OOl). Ninety-six percent ofpatients undergoing PA catheter investigation had either congestive heart failure (CHF), hypotension or cardiogenic shock. For the combined time periods, the in-hospital case fatality rate (CFR) for

متن کاملFactors associated with prehospital delay in patients with acute myocardial infarction
Introduction: Treatment of patients with acute myocardial infarction (AMI) is time related, so delay in treatment could affect prognosis. Recognizing pre-hospital or in-hospital delays in initiating treatment and reducing these factors is very efficacious in treatment of these patients. Methods: A cross sectional study was carried out on 227 patients with acute myocardial infarction. Demographi...
متن کاملPrognostic Impact of Thrombolysis in Myocardial Infarction Risk Index on Hospitalization Mortality of Patient with Acute Pulmonary Embolism
Introduction: Acute pulmonary embolism (PE) is one of the deadly cardiovascular diseases. One of the indexes proposed in these patients for risk stratification is the Thrombolysis in Myocardial Infarction (TIMI) risk index (TRI), which includes three parameters of systolic blood pressure, age, and heart rate. This study aimed to evaluate the predictive value of TRI on in-hospit...
