- W2612366461 abstract "Early diagnostics of chronic heart failure (CHF) offers great difficulties. In this investigation Echocardiography by taking into account the Golden section principle was used. 156 patients with arterial hypertension and coronary artery disease were examined. The change of sizes and volumes of the left ventricle (LV) and their relations is established. In the control group (n=37) end systolic diameter (ESD) 3,2±0,1, end systolic diameter (ESD)/ end diastolic diameter (EDD)0,632±0,002, end systolic volume (ESV)/ end diastolic volume (EDV) 0,373±0,003, end systolic volume (ESV)/systolic volume (SV) 0,589±0,01 and systolic volume (SV)/ end diastolic volume (EDV)0,632±0,003 of LV have been defined. The character of the change of these parameters depended on the degree of CHF. In the first group (n=44) with I class NYHA of CHF the reduction of ESD 2,83±0,14*, ESV/EDV 0,322±0,004, ESV/SV 0,481±0,014 and the increase SV/ESV0,677±0,004 were defined. In the second group (n=48) with II class NYHA of CHF normal volumes LV, the increased size of left atrium and ESD/EDD 0,656±0,002 were defined. The characteristic feature in the third group (n=25) with III class NYHA of CHF is the increase in the sizes and volumes LV and their relations at decrease SV/EDV 0,405±0,01 (ejection fraction). Low values SV/EDV 0,271±0,014 are revealed at patients of the third group (n=16) IV class NYHA of CHFwith the expressed increase in the other indicators." @default.
