The Correlation Between Symptoms Severity of Left Ventricular Systolic Heart Failure and Tissue Doppler Indices (original) (raw)

Journal of Cardiology & Current Research

There are two types of heart failure patient's exercise performance methods: subjective and objective. The subjective methods include NYHA classification, various activity scales, and quality of life specific questionnaires. The objective methods include various modes of exercise testing to document submaximal exercise capacity (6-minute corridor walk test and anaerobic threshold analysis), as well as maximal exercise capacity (exercise time and maximal oxygen consumption measurement) [2]. A variety of noninvasive imaging modalities are available for assessment of patients with heart failure. These include echocardiography, TDI, radionuclide imaging, and cardiovascular magnetic resonance imaging (CMRI), without any correlation to symptoms severity of left ventricular systolic
