[Epidemiology of pulmonary embolism in patients with cardiac department].

Unlabelled: Pulmonary embolism (PE) is a blockage of the main artery of the lung or one of its branches by a embolic material. ZP is usually a manifestation of venous thromboembolism (VTE), which in addition to the ZP includes deep vein thrombosis. The aim of this study was to analyze the epidemiology of pulmonary embolism in patients in the cardiology department with regard to gender and age. Material for the study was the medical documentation of patients hospitalized in the Department of Cardiology Hospital Louis Rydygiera in Cracow in the period of 7 years (1 I 2004 - 31 December 2010). During this time 11,435 patients were hospitalized. The study included 67 (1.23%) patients (31 men, 36 women) aged 30 - 93 years (mean 70.3 years, SD 13.3) who were diagnosed with acute pulmonary embolism. Collected information on gender, age, body weight and coexisting disease. An analysis of the documentation in terms of symptoms on admission and the cause of pulmonary embolism.

Results: The study included 67 patients, aged 30 - 93 years (mean age 70.3 years, SD 13.3) including 31 males (mean age 71.7 years, SD 13.8) and 36 women (average age 69.1 years, SD 12.9). The incidence of pulmonary embolism was 6 people per 1000 hospital admissions (0.58%). The average age of women was lower compared to men (69.1 +/- 12.9 vs. 71.7 +/- 13.8 years). Among the most common coexisting diseases were coronary heart disease (44.8%), hyperlipidemia (40.3%) and varicose veins of the lower limbs (49.3%). The most common symptoms on admission were dyspnea (88.1%), chest pain (59.7%) and hypotension (44.8%). Among the predisposing factors for pulmonary embolism occurs most frequently in the history of surgery (55.2%), venous thrombosis of lower limbs (50.7%), smoking (34.3%). The median age was 70.3 years. Pulmonary embolism was significantly more common among older people (37.3% vs. 62.7%, p = 0.04) and in men (35.5% vs. 64.5%, p = 0.04) and women (38.9% vs. 61.1%, p = 0.04). Pulmonary embolism was reported most frequently in the age group between 70-79 years of age in the study group (43.3%).

Conclusions: 1. Pulmonary embolism occurs in 6 per 1000 patients hospitalized in the cardiology department. 2. Pulmonary embolism occurs most frequently in the age group 70-79 years. 3. The most common factors that causes pulmonary embolism are state after surgery and a history of deep vein thrombosis.
