5.Methods: The serum BNP concentration of 102 CHF patients and 30 controls were measured by electrochemiluminoimmunoassay(ECLA),and left ventricular ejection fraction(LVEF) and cardiac index(CI) were detected by color Doppler. Thirty-one randomized patients in CHF group were examined by nuclide gated cardiac blood pool imaging in order to determine LVEF at rest.
6.The P terminal force V_1(PTFV_1)of 80 cases of elderly coronary heart disease(CHD)and 20 cases of elderly healthy persons were compared with those of the gated cardiac-blood pool imaging The results indicated that PTFV_1,the left ventricular ejection fraction(EF),the left ventricular peak filling rate(PFR)and the atrial systolic fraction(ASF)of the elderly CHD group were significantly different from those of the elderly healthy group.
