[Cardiovascular function in leptospirosis convalescents]

To study mechanisms of cardiovascular damage in leprospirosis convalescents.

Cardiovascular system was investigated in 121 leptospirosis convalescents at the age 17-58 years clinically, electrocardiographically and measuring troponin-T in blood serum.

6-12 months after leptospirosis 42.1% of patients who had leptospiral jaundice (88.4%) and bovine leptospirosis (21.6%) myocardial damages were revealed. In spite of disappearance of cardiac pain ECG readings did not return to normal. The myocardial damage has developed in the advanced stage of leptospirosis due to rhandomyolis: high concentration of myoglobin and troponin-T in the blood serum confirms this suggestion.

Clinical ECG readings as well as the level of troponin-T in the blood serum may be considered as the index of rehabilitation level in leptospirosis convalescents. It should be taken into consideration that 19.8% of the convalescents develop hypertension of renal genesis. This should be accounted for when planning prophylaxis and rehabilitation programs for young patients living in the North Caucasus--natural source of leptospirosis.
