Effects of ligustrazine controlled release capsule in chronic pulmonary heart disease.

Before and after oral administration of ligustrazine controlled release capsule, pulmonary hemodynamics, right cardiac function, arterial blood gas and TXB2/6-keto-PGF1 alpha were studied in 16 patients with advanced cor pulmonale. The decrease of pulmonary arterial pressure and pulmonary vascular resistance, increase of cardiac output, improvement of right cardiac function and arterial blood gas were demonstrated after one course of treatment. The mechanism of these effects may be related to improvement of imbalance of TXB2/6-keto-PGF1 alpha. These results were in agreement with those of intravenous administration of ligustrazine, but no adverse reactions were found.

Pulmonary heart disease: pathophysiology, diagnostic signs, and therapy.

The anatomy and physiology of the pulmonary vasculature has been described with emphasis on several types of pulmonary hypertension and their pathophysiology. Treatment of pulmonary hypertension may be successful, especially when disease is related to emboli which respond to anticoagulant therapy. Relief of mitral valve obstruction is usually beneficial. Patients with abnormalities of blood PO2 and pH (especially in chronic obstructive lung disease) may be spared increased pulmonary pressure or may reverse existing pulmonary hypertension by giving up smoking, learning more efficient ventilatory methods, and when indicated, using supplemental oxygen, bronchodilators, digitalis, diuretics, or a combination of these.

[The value of transesophageal echocardiography for the diagnosis of pulmonary embolism with acute pulmonary heart disease].

Transoesophageal echocardiography is a method of visualising intracardiac thrombi and could therefore be useful for the diagnosis of pulmonary embolism, but its diagnostic value is unknown. The authors carried out a prospective study with this diagnostic tool in massive pulmonary embolism. The study protocol was to perform transthoracic echocardiography in patients with suspected acute pulmonary embolism and then to perform transoesophageal echocardiography when there were signs of acute cor pulmonale. The results of both echocardiographic investigations were compared with two reference radiological techniques: the spiral CT scan and/or pulmonary angiography. Fifty-six patients underwent transthoracic echocardiography. In the 34 patients with transthoracic echocardiographic signs of acute cor pulmonale, the positive predictive value of the investigation for pulmonary embolism was 91% and the negative predictive value was 54%. Twenty of these 34 patients underwent transoesophageal echocardiography. The sensitivity and specificity for the diagnosis of proximal embolism were 85% and 86% respectively. The limitations of the method were poor visualisation of the left pulmonary artery in which only one thrombus was detected, compared with 6 by spiral CT scan, and the absence of visualisation of lobar arteries. Consequently, the real sensitivity of transoesophageal echocardiography for visualisation of all thrombi in the pulmonary arteries in acute cor pulmonale was only 55%. In acute cor pulmonale, the diagnostic value of transoesophageal echocardiography is poor because the sensitivity for visualisation of intra-pulmonary arterial thrombi is low compared with other radiological techniques. However, in patients with proximal emboli in the right or main pulmonary artery, the diagnosis may be established in a few minutes without the need of other more invasive techniques. Nevertheless, normal transoesophageal echocardiography does not rule out the presence of proximal in the left pulmonary artery or distal emboli in the lobar arteries.

[Correction of hemodynamic disorders in phthisiologic surgical patients with chronic pulmonary heart disease in preoperative period].

The hypokinetic blood circulation was detected in 49% (from a total of 180) patients with different forms of pulmonary tuberculosis. Obvious initial signs of disorders in the function of the cardio-vascular system were diagnosed in one half of patients with the normal kinetic blood circulation. 48 patients underwent a preoperative treatment to correct the hemodynamic disorders. Isosorbide dinitrate (5 mg/day), verapamilhydrochlorid (240 mg/day), maleate enalapril (5 mg/day) and isosorbide dinirate (80 mg/day) were administered simultaneously. The preoperative preparation of patients lasted from 4 to 7 days. The cardiac beat, and the mechanical index of the functioning of the left ventricle essentially improved, while the total peripheral resistance significantly decreased due to all treatment schemes. Isosorbide dinitrate and verapamilhydrochlorid produced the most effect on the parameters of the central hemodynamics. The administration of all above preoperative preparation schemes in patients with pulmonary tuberculosis reduces the operation-anesthesiology risk.
