Methods： Seventy-six patients and 30 normal subjects were first examined by echocardiography. Brachial artery dilatation induced by reactive hyperemia （DIRH） or nitroglycerin （DING） was detected using high-resolution ultrasonography. Results： DIRH was lower in patients with hypertension than in the controls, and the decrease in DIRH was greater in the patients with LVH than that in patients without LVH （4.36±2.54% vs 8.56 ± 1.87 %; P 〈 0.0001）. There were no significant differences in age, serum concentrations of total cholesterol, triglycerides or sugar, blood pressure and the brachial artery dilatation induced by nitroglycerin between the two groups （P 〉 0.05）. While there was no significant difference in DIRH between the patients with normal left ventricular geometry or cardiac remodeling, the patients showing either eccentric or concentric left ventricular hypertrophy had lower DIRH than the patients with normal left ventricular geometry or cardiac remodeling. The DIRH was the lowest in patients with concentric hypertrophy. Although bivariate analysis showed that the left ventricular mass index （LVMI） correlated well with the brachial artery dilatation induced by reactive hyperemia, diastolic blood pressure and mean blood pressure （r=-0.61, P 〈 0.0001; r=0.27, P 〈 0.05; r=0.31, P 〈 0.05, respectively）, a multivariate stepwise regression demonstrated that LVMI correlated only with the brachial artery dilatation induced by reactive hyperemia. Conclusion： Left ventricular hypertrophy was related to endothelial dysfunction in essential hypertension. The endothelial dysfunction might be basic and important in the progression of left ventricular hypertrophy.展开更多

LVH and diastolic dysfunction are associated with elevated sympathetic activity and increased morbidity and mortality. The effect of RD on LVH and LV function is unclear展开更多

All these conditions may affect left ventricular (LV) geometry, mass and diastolic function. The purpose of this study is to early detect these affections to improve heart failure prevention. Patients and methods: 134 women, affected by breast cancer, underwent to conventional transthoracic echocar-diography (TTE) and pulse wave tissue Doppler imaging (PW-TDI). A control group (CG) of 80 women unaffected by breast cancer, hypertension and diabetes was enrolled. Results: 54 of 134 women (40.2%), were affected by hypertension or diabetes too (Prone Group = PG), 8 by both, 80 (59.8%) were free (FG). Mean age of all patients was 45.4 years. The rates of LV eccentric hypertrophy and LV distolic dysfunction were statistically significant higher on FG group than controls, and on PG group than FG group. Conclusions: an abnormal LV diastolic function is more common among women affected by breast cancer after treatment than in general population, the same for LV eccentric hypertrophy but at a lower rate. 40% of women were affected by hypertension, diabetes or both, and as expected they have a higher rate of LV eccentric hypertrophy and diastolic dysfunction. This high prevalence of LV eccentric hypertrophy and diastolic dysfunction, on asymptomatic women, affected by breast cancer, is a predictor of heart failure;Doppler-echo techniques may be helpful in early diagnosis.展开更多
