Abstract:
Objective To analyse the clinical feature of infective endocarditis (IE) in recent years.Methods Clinical profiles including age of onset,predisposing factor,clinical manifestation,blood culture and ultrasonic cardio gram (UCG) of 97 cases from Huashan Hospital in the recent 10 years were collected and analyzed retrospectively. Descriptive data were represented as mean ±standard deviation form.Positive rate was represented as percentage form.Fisher's exact test were used to determine two groups' comparison.Results The mean age of the population was (49±17)years.Seventy-three patients (75.3％) had background heart disease,the top 3 of which was rheumatic heart disease in 27 patients (27.8％),congenital heart disease in 23 patients (23.7％) and idiopathic mitral valve prolapse in 18 patients (18.6 ％).The most common clinical manifestation were fever (99.0％),murmurs (95.9％) and anemia (84.5％).Sixty-six patients (68.0％) had positive result of blood cultures. Streptococcus viridans,which was found in 28 patients with native valve endocarditis (42.4 ％),was still the most common pathogen.Staphylococcus,which was found in 18patients (27.3％),had an elevated ratio.Staphylococcus aureus was found in 10 patients (15.2％)and 3 of which were MRSA.Coagulase-negative staphylococcus was found in 8 patients (12.1 ％ ) and 2 of which were MRCNS. Drug-resistant bacteria was increased and pathogens were varied.Vegetations were found in 79 patients (81.4％) by UCG.ConclusionsClinical manifestation,predisposing factor and pathogen have changed in IE patients. Attaching importance to physical examination,multiple-time blood culture and UCG helps the diagnose of IE.
