The influence of hypoxia on the activity of voltage-gated potassium channel in pulmonary artery smooth muscle cells (PASMCs) of rats and its roles in the pathogenesis of chronic pulmonary heart disease were investigated. Eighty male Sprague-Dawley rats were randomly allocated into control group
Total body potassium was measured in 12 patients with cor pulmonale, by determination of potassium-40, a naturally occurring radioisotope. In all subjects the observed value of total body potassium showed no significant depletion when compared with that predicted from height and age. All previous
Chronic cor pulmonale is defined as right heart hypertrophy or right ventricular dilatation and/or chronic right heart failure. There are many etiologies which largely determine mortality and drug therapy, but the common cause is increased right ventricular work from primary or secondary pulmonary
This paper reported the results of 24 hours continuous ECG, day time and overnight arterial blood gas/pH and serum electrolytes in 20 patients with cor pulmonale, in order to investigate the rule of changes of ventricular arrhythmias (VA). The results were as follows: (1) Incidence of VA in 24 hours
OBJECTIVE
To study efficiency and safety of application of perindopril (prestarium) in patients with chronic cor pulmonale (CCP).
METHODS
The trial included 26 patients with chronic obstructive pulmonary disease complicated with CCP and cardiac failure of NYHA class II-III. The study group of 16
BACKGROUND
Chronic hypoxia can cause pulmonary hypertension and pulmonary heart disease with high mortality. The signal transduction pathway of protein kinase C (PKC) plays an important role in chronic pulmonary hypertension. So it is necessary to investigate the effect of PKC on voltage-gated
Seventeen male patients with chronic obstructive airways disease in remission were separated into two groups according to arterial carbon dioxide tensions. Hypercapnia was associated significantly with hypoxia and increased red cell volume whereas normocapnia was not. Normocapnic patients were
Pulmonary arterial hypertension (PAH) is a rare and severe cardiopulmonary disease without curative treatments. PAH is a multifactorial disease that involves genetic predisposition, epigenetic factors, and environmental factors (drugs, toxins, viruses, hypoxia, and inflammation), which contribute to
Serum testosterone, follicle-stimulating hormone, luteinising hormone, and dihydro-epiandrosterone concentrations rose significantly in seven men studied during recovery from a severe exacerbation of chronic obstructive airways disease. Urinary 17-ketosteroids also rose significantly though serum
1. Body weight was measured through forty consecutive illnesses in seventeen patients with oedema in association with chronic bronchitis and hypoxia. All patients were taking diuretic drugs at the time. 2. Body weight increased little as peripheral oedema and a raised jugular venous pressure
Humans encounter hypoxia throughout their lives. This occurs by destiny in utero, through disease, and by desire, in our quest for altitude. Hypoxic pulmonary vasoconstriction (HPV) is a widely conserved, homeostatic, vasomotor response of resistance pulmonary arteries to alveolar hypoxia. HPV
The purpose of this study is to evaluate the safety and efficacy of 120-W potassium titanyl phosphate (KTP) laser vaporization in patients with benign prostatic hyperplasia (BPH) who also had cardiopulmonary diseases who were taking long-term anticoagulants and were at high risk of bleeding
