Echocardiography - prognosis of the course of infectious endocarditisand long-term survival in this disease
Abstract
Aim. To determine prognostic opportunities of echocardiography (ECG) in infectious endocarditis (IE) basing on the assessment of microbial vegetations size and degree of valvular failure. Material and methods. Of 114 patients with definite IE (72 male, 42 female), 90 ones had primary and 24 secondary endocarditis. The prospective study included all the survivors in the IE active stage -78 patients. Results. Vegetations > 1 cm in size were detected in 50.8%patients, 1 cm and 1 cm, respectively. Valvular regurgitation of the first degree was in 17.5%, of the second degree - in 41.9%, thirdfourth degree - in 36.6% patients. Hospital lethality in mitral valve failure was 32.1%, in aortic and tricuspid failure - 17.8 and 11.4%, respectively. Conclusion. EchoCG was most effective for predicting thromboembolism and cardiac failure. Valvular regurgitation of the third-fourth degree significantly correlates with severe cardiac failure. ECG is less informative for predicting hospital lethality.
