OBJECTIVE
Obstructive sleep apnea hypoxia syndrome (OSAHS) is an independent risk factor for coronary artery disease (CAD). Treatment of OSAHS improves clinical outcome in some CAD patients, but the relationship between OSAHS and CAD is complex. Microparticles (MPs) are shed by the plasma membrane
OBJECTIVE
To assess the influence of acute hypoxemia on the dimensions of diseased and nondiseased coronary arterial segments in humans.
METHODS
In 18 subjects (age 53 +/- 8 years) with known or suspected coronary artery disease, quantitative coronary angiography was performed before and after being
A disorder in the physiological structure of the sleep cycles (macrostructure) is known to occur both in patients with sleep apnoea (SA) and coronary heart disease (CHD). The study presented here was concerned with the problem whether the sleep structure in patients suffering from CHD and
OBJECTIVE
This study aimed to investigate the association of Hypoxia-inducible factor-1α (HIF-1α) C1772T and G1790A single nucleotide polymorphisms (SNPs) with: incidence, clinical type, severity of coronary atherosclerosis and coronary collaterals of coronary artery disease (CAD).
METHODS
The
OBJECTIVE
Marked variability exists in coronary artery collaterals in patients with ischemic heart disease. Although multiple factors are thought to play a role in collateral development, the contribution of genetic factors is largely unknown. Hypoxia inducible factor 1 (HIF-1), a transcriptional
The occurrence of breathing disorders and hypoxia during sleep was studied in 17 male patients with coronary artery disease, demonstrated by coronary angiography, who did not have symptomatic pulmonary disease. Thirteen patients (76 percent) experienced disordered breathing during sleep; of these,
Ischemic heart diseases are caused by narrowed coronary arteries that decrease the blood supply to the myocardium. In the ischemic myocardium, hypoxia-responsive genes are up-regulated by hypoxia-inducible factor-1 (HIF-1). Gene therapy for ischemic heart diseases uses genes encoding angiogenic
Sleep-disordered breathing (SDB) or short sleep duration and coronary artery disease (CAD) are related, yet, the prevalence of SDB and short sleep duration as well as their mechanism remain unknown. Enhanced vascular inflammation is also implicated as one of the pathophysiologic mechanisms in CAD.
BACKGROUND
Marked variability exists in coronary artery collaterals in patients with ischemic heart disease. Multiple factors are thought to play a role in collateral development; however, the contribution of hypoxia inducible factor-1alpha (HIF-1alpha), which is a transcriptional activator that
A major challenge in developing new treatments for myocardial infarction (MI) is an improved understanding of the pathophysiology of hypoxic tissue damage and the activation of endogenous adaptive programs to hypoxia. Due to the relevance of oxygen in metabolism, molecular adaptation to hypoxia
BACKGROUND
The increased expression of heme oxygenase-1 content, a stress-response protein, directly correlates with the incidence of coronary heart disease. Down-regulation of hypoxia inducible factor-1alpha activity, a major downstream effector of the signaling pathways activated by hypoxia,
The objective of the study was to evaluate the effects of intermittent hypobaric hypoxia (IHH) on plasma lipid concentrations of male coronary heart disease (CHD) patients. Forty-six male coronary patients were enrolled in the study. Thirty had a history of myocardial infarction and 16 had ischemic
BACKGROUND
Repeated exposure to intermittent normobaric hypoxia improves exercise tolerance in cardiac patients. Little is known on the effects of intermittent normobaric hypoxia-hyperoxia exposure in coronary artery disease (CAD) patients (New York Heart Association II-III).
OBJECTIVE
IHHT improves
Objective: To investigate the effects and mechanism of miR-145-5p on hypoxia/reoxygenation (H/R)-induced cardiac microvascular endothelial cell (CMEC) injury in coronary heart disease (CHD).
Patients and
BACKGROUND
Intermittent hypoxia has been suggested to increase exercise tolerance by enhancing stress resistance and improving oxygen delivery. Because the improvement of exercise tolerance reduces mortality in the elderly with and without coronary artery disease intermittent hypoxia might be a
