Abstract
BACKGROUND: An increase in short-term mortality can be found among older patients with hemodynamically stable acute pulmonary embolism (APE) who have signs of right ventricular (RV) dysfunction. AIMS: This study was designed to assess whether any difference exists among clinical, laboratory, electrocardiography and echocardiography parameters between older and younger patients diagnosed with APE. METHODS: The study sample included a total of 635 patients with confirmed APE who were divided into two groups of older (65 years and older) and younger (younger than 65 years) individuals. Comparisons were performed between these groups in terms of clinical, predisposing factors and laboratory, electrocardiographic and echocardiographic parameters. RESULTS: Analyses of 295 (46.4%) older and 340 (53.6%) younger patients diagnosed with APE were performed. Female sex, Pulmonary Embolism Severity Index score and baseline creatinine levels were higher in the older group. Also, the frequency of atrial fibrillation, RV outflow tract parasternal long-axis proximal diameter, RV end-diastolic diameter (RV-EDD) basal (apical four-chamber) and RV systolic pressure were significantly greater in older patients with APE. A total of 30 (4.7%) deaths were observed during the in-hospital period [21 (7.1%) older vs 9 (2.6%) younger patients; p < 0.01]. In the multivariate logistic regression analysis, age, white blood cell count (WBC), left ventricular ejection fraction (LVEF), RV-EDD basal and tricuspid annular plane systolic excursion (TAPSE) of less than 16 mm were found to be independently associated with in-hospital mortality. CONCLUSION: Older patients might experience greater rates of RV dilatation, RV dysfunction and atrial fibrillation during APE. In addition to age; elevated WBC, low LVEF, increased RV-EDD basal and TAPSE of less than 16 mm were independent predictors of mortality among study population.
