The smoking level and the lung ventilatory function was measured on 30 patients with COPD (19 males, 11 females, mean aged 68.3+/-11.5) and 30 non-smoking controls (17 males, 13 females) without cardio-vascular and respiratory diseases at HuÕ Central Hospital. Results: There is not any correlation between respiratory function measurements and Doppler echocardiographic measurements. The smoking level as measured by packages per year has close correlation with the decrease in respiratory function (r = -0.73, p = 0.01). The combination of many Doppler echocardiographic measurements is helpful in evaluating the pulmonary hypertension in patients with COPD.

A study on 30 patients with COPD with average ages of 68,3+/-11,59 and 30 healthy people with the same age has shown that the arterial blood gas helped to classify the respiratory failure, especially in the acute crisis of COPD, indicate the oxygen therapy for improving the condition of oxygen deficiency but did not help to predict the pulmonary arterial pressure. There was a difference of volume equity dilatation time and AT between disease group and control. There was relatively to closely correlation between RVP, PAPm, PAPs.

A study on 40 patients with ages of 15-82 diagnosed as aortic valve stenosis by clinical symptoms, eletrocardiogram and echocardiography Doppler has shown that most of patients had aortic valve stenosis combining with mivtral stenosid. AVD in most of patients was reduced. The aortic valve stenosis influenced directly on the most of the left myocardial (85%) including the left myocardial thickness and dilatation.
