Analysis of clinical characteristics of 89 patients with infective endocarditis / 中国基层医药

ABSTRACT

Objective To improve the diagnosis and treatment of infective endocardits(IE)by exploring the causes,pathogenic microorganism,clinical characteristics and therapeutic results of patients with IE.Methods From January 2006 to January 2016,89 cases with IE in Ganzhou People's Hospital were collected,and the clinical charac-teristics were analyzed retrospectively.Results Among the IE patients,40.5%had congenital heart diseases,33.7%had rheumatic heart diseases,18.0% were post－PCI or operative endocarditis,and patients without basic cardiac diseases accounted for 7.9%.The most common clinical manifestations were fever (86.5%),followed by anemia (85.4%).The blood culture positive rate was 63.4%.Streptococci viridians were the most common causative organ-isms(44.2%),followed by coagulase －negative staphylococci(21.2%).Eighty－six patients received echocardio-graphy examination,vegetation was observed in 61cases (68.5%).The hospital mortality rate was 10.1%,mostly due to refractory congestive heart failure and sepsis.Conclusion Congenital heart disease showed an upward trend, rheumatic heart disease decreased significantly.Intermittent fever,anemia are the main clinical manifestations.Blood culture positive rate is not high,Streptococcus viridians is the most common causative organism.Echocardiography is the main basis for the diagnosis.
