All patients with chronic obstructive pulmonary disease who received angiotensin-converting enzyme inhibitors or angiotensin receptor blockers for more than 90 days between 2000 and 2005 were recruited for this study.
Vitamin D receptor FokI and BsmI genotypes and the (I/D) angiotensin-converting enzyme (ACE) and bradykinin receptor (+9/-9) genotypes were identified in 107 patients with stable COPD [x +/- SD forced expiratory volume in 1 s (FEV(1)): 34.5 +/- 16.5] and 104 healthy, age-matched control subjects.
These findings suggest that the ability of oxygen administration to improve tissue oxygenation during exercise is associated with the ACE genotypes in COPD patients.
We previously showed that the D rather than the I polymorphic variant of the angiotensin-converting enzyme (ACE) gene is associated with preserved quadriceps strength in COPD.
In HHF, the increase in the use of heart failure (HF) medications at hospital discharge was greater in non-COPD than in COPD for angiotensin-converting enzyme inhibitors (+13.7% vs. +7.2%), beta-blockers (+20.6% vs. +11.8%) and mineralocorticoid receptor antagonists (+20.9% vs. +17.3%), thus widening the gap in HF treatment already existing between the two groups at admission.
Our meta-analytical findings demonstrated that the ACE gene I/D polymorphism was not associated with the risk of chronic obstructive pulmonary disease.
The DD genotype of the angiotensin converting enzyme gene is negatively associated with right ventricular hypertrophy in male patients with chronic obstructive pulmonary disease.
In this cross-sectional controlled study, we aimed to investigate the role of polymorphisms of the angiotensin-converting enzyme (ACE) and endothelial nitric oxide synthase (eNOS) genes on pulmonary hypertension (PH) in patients with chronic obstructive pulmonary disease (COPD).
We aimed to investigate the effects of endothelial nitric oxide synthase (eNOS A/B), angiotensin converting enzyme (ACE I/D) and serotonin transporter (5-HTT L/S) gene polymorphisms on development and severity of PH in COPD patients.
Effects of captopril administration on pulmonary haemodynamics and tissue oxygenation during exercise in ACE gene subtypes in patients with COPD: a preliminary study.
Albuminuria could identify patients with COPD in whom angiotensin-converting enzyme inhibitor therapy improves renal and lung function by reducing endothelial injury.
Angiotensin-converting enzyme (ACE) plays an important role in vascular remodeling in pulmonary hypertension, and ACE gene polymorphism is associated with exercise-induced pulmonary hypertension in Japanese patients with chronic obstructive pulmonary disease.
Similarly, there were no significant differences in AT, maximal O(2) uptake, maximal O(2) pulse, maximal dyspnoea index, ventilatory response (DeltaVE/DeltaVCO(2)), O(2) cost of ventilation (VO(2)/W/VE), end-tidal partial pressure of carbon dioxide at maximal exercise and maximal SaO(2) among the three ACE genotype COPD patients.
Fewer patients with COPD received β-blockers (adjusted odds ratio 0.66, 95% CI 0.59-0.74), angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (adjusted odds ratio 0.83, 95% CI 0.73-0.93), statins, anticoagulants, dual antiplatelets, and coronary interventions.
We have observed an association of the ACE D/D genotype with a large number of common diseases, including chronic renal failure due to non-insulin-dependent diabetes mellitus or hypertension, hypertensive peripheral vascular disease, and emphysema [chronic obstructive pulmonary disease (COPD)].
The review will, in particular, address the emerging evidence that ACE inhibition could have a beneficial effect on skeletal muscle function and cardiovascular co-morbidity in COPD patients.
These findings suggest possible association of the functional ACE D allele with altered vascular responses that may modulate development of distinct COPD symptoms.
