Retrospective Analysis Of Clinical Data On Patients With Pulmonary Embolism In Recent40Years

Objective:To review the evolution and development results of clinical symptoms, signs, diagnosis and treatment and discuss the influence with gender and age on patients with pulmonary embolism in recent40Years, in order to improve the understanding of the disease.Methods:All pulmonary embolism cases which were hospitalized between July1973and February2012in the second hospital of Tianjin medical university were collected and reviewed retrosPEctively. Clinical data of all of the patient included the blood routine, liver function, arterial blood gas analysis, blood fat, D-dimer, elect-rocardiogram, echocardiography, lower limb vein ultrasound, the diagnosis of eme-rgency treatment or outpatient service, treatment and clinical outcome. All cases were divided with a decade interval into three groups:A (～1992), B (～2002), C (～2012). According to the age divided into two groups:the≥60years old group and the<60years old group. According to gender divided into male and female group.182cases of hospitalized patients with D-dimer check were analysed. According to guide [1], the cases were divided into two groups:the d-dimer positive group (≥0.5mg/L); The d-dimer negative group (<0.5mg/L). All data were collected by SPSS17.0.Results:276cases were enrolled, of which there were men cases146cases (52.9%), and women cases130(47.1%). Mean age was21-86(60.21±14.10) years old. Patients had an increasing tendency with the decade advancing, and the young patien-ts had generation decreases, esPEcially in recent ten years, without difference between the gender. The hospital stays were reduced with the decade advancing, the susPEcted PE of PE patients in outpatient and emergency were reduced with the decade advanci-ng because of the diagnosis technology progressing. The three signs of clinical symp-toms and the signs of the PE patients were reduced with the decade advancing, the PErcentage of male patients group was higher than female patients group. The PErce-ntage of the patients with complication of hypertension or diabetes were increased with the decade advancing, and there were more patients than the≥60years old group. There were more patients with the malignant tumor in the≥60years old group, male group, the d-dimer positive group. The patients with the surgery and injury history were increasing year by year, and the patients with bedridden history were decreasing, of which there were morn patients in the≥60years old group. The patients with the auxiliary examination, confirmed diagnosis, treated, improved, were increasing with the decade advancing.Conclusion:PE patients had an increasing tendency with the decade advancing. The three signs of clinical symptoms were reduced with the decade advancing.The PErcentage of the patients with complication of hypertension or diabetes were incre-ased with the decade advancing. The patients with the auxiliary examination, confi-rmed diagnosis, treated, improved, were increasing with the decade advancing.
