Daily clinical analysis of the treatment of elderly heart failure. The Daly whole treatment group showed a significant improvement in left ventricular ejection fraction after treatment, which was significantly different compared to the conventional treatment group. There were no significant changes in blood pressure in the two groups before and after treatment; cardiac function before and after treatment, ultrasound therapy accounted for 85.0%; Daly treatment group before treatment, cardiac function, echocardiography, Abercrombie and Fitch, blood pressure and heart rate are shown in Table 1. Table 12 treatment, the heart rate, blood pressure, cardiac function and echocardiography before and after comparison (interaction ± s) Note: and Daly treatment group before treatment, P < O. 01; after treatment with conventional therapy group, P < O. 05, P < 0013 discussed in recent years a large number of studies have shown that in CHF patients often enhanced sympathetic activity and renin-angiotensin-aldosterone system is activated, circulating catecholamines, the renin-angiotensin levels, on the one hand a direct result of systemic vasoconstriction, increased the heart before and after the load, damage to the myocardium, leading to myocardial dysfunction; the other hand, catecholamines by stimulating l3 receptors play a positive inotropic effect, but high concentrations, prolonged stimulation can reduce l3 the number of receptors. The appears f3 receptor down l3J. Several large randomized clinical trials have confirmed that the l3 blockers can reduce mortality in patients with heart failure 4l5j. Application l3-blockers can reduce plasma catecholamine levels, reducing myocardial oxygen consumption, reduce levels of angiotensin Ⅱ, reducing cardiovascular oxidative damage, reducing myocardial cell death and apoptosis, thereby improving heart function and slow the progression of the disease ~~ 6j. Daly, a full non-selective l3-blockers, in addition to blocking the , & Receptors, also blocked a. Receptors, smooth muscle relaxation in blood vessels to dilate significantly reduced preload and afterload of the heart, reducing myocardial tension, reducing the left ventricular internal diameter. The purpose of this study is to observe the Dali full efficacy in patients with CHF. We found that the Dali full treatment on the basis of the conventional treatment plus follow-up after 6 months of observation, Daly treatment group symptoms and heart function was improved significantly improve left ventricular ejection fraction, left ventricular end diastolic diameter reduced diameter, end-systolic, heart rate, and are superior to the conventional therapy group. This group had one cases of hypotension and worsening heart failure by reducing Daly dose and increase diuretic dosage symptoms improved. In this study, all patients had no half-way stopping the phenomenon. In short, on the basis of conventional therapy Daly treatment of CHF a significant effect, treatment and survival of great value.
