Echocardiography Method Of Assessing Myocardial Contract Function In Essential Hypertention Of Different Remoldings

Left ventricular (LV) systolic performance has often been assessed mainly as the LV myocardial contract, pump and chamber function. When using endocardial fractional shortening (eFs) , relation between eFs and circumferential end-systolic stress (eFs-cEss) assess chamber function in patients with hypertension of four LV remoldings, it shows apart from eccentric hypertrophy, eFs,eFs-cEss of the rest three remoldings are overestimative, midwall fractional shortening (mFs) assessed contract function in four remoldings are lower than the controls especially in concentric hypertrophy patients. Data points for a substantial number are below the lower limits of normal control 95% confidence interval of the relation between mFs and cEss, of which were 60.3% concertric hypertrophy and 38.46% concentric remolding patients. These demenstrate that mFs, mFs-cEss can assess senstitively the LV systolic performance of patients with hypertension with different geometric remoldings. The LV eject force (F) of four remoldings is afterload-dependence and can't assess their systolic performance .
